    Aim of this review is to describe the role of clinical toxicology in the context of acute medicine. A special focus is put on antidotes and important aspects of diagnosis and therapy of acute intoxications. The data of the annual report of GIZ-Nord Poisons Centre is analyzed concerning the following aspects: what intoxications are relevant in acute medicine, are there special aspects in therapy, e.g. antidotes, and what antidotes are relevant? More over intoxication-related fatalities are analyzed. In 2015 the poisons centre was consulted in 33,000 cases of acute intoxications. The most important groups are drugs (e.g. antidepressants, beta blockers and calcium channel blockers), chemical products (e.g. products containing surfactant, corrosive substances and toxic alcohols like methanol), plants and recreational drugs. Intoxications are relevant in acute medicine. Some substances can cause fatal intoxications. Important antidotes are naloxone for opiods, acetylcystein for paracetamol, fomepizole and ethanol for toxic alcohols and diazepam for intoxications caused by chloroquine.

    Full Text Available Clozapine is an atypical antipsychotic drug prescribed for treatment-resistant schizophrenia. The risk of adverse hematologic, cardiovascular, and neurologic effects has tempered its use, and reports of overdoses remain rare. We report a case of accidental acute clozapine intoxication in a clozapine-naïve patient, who presented with symptoms mimicking acute stroke and later developed status epilepticus. Clozapine intoxication is a rare presentation in the emergency department with potential for iatrogenic harm if not correctly identified.

    Full Text Available The article is dedicated to the issue of intoxication in children. Acute accidental intoxication appears to be especially relevant for pediatric practice. Drugs, various chemicals frequently used in everyday life and in farming, as well as animal poisons, including snake poisons, may have a toxic effect on children. Specialists of professional associations of physicians “Russian Society of Emergency Medicine” and pediatricians “Union of Pediatricians of Russia” formulated and briefly described the main causes of acute intoxication in children, clinical manifestations and the most significant laboratory indicators of toxic manifestations for various substances, as well as therapy principles and algorithms for such conditions in compliance with principles of the evidence-based medicine. The article presents pathognomonic symptoms and peculiarities of drug intoxication, provides a description of mediator symptoms of intoxication with various substances, as well as the symptoms that may indicate toxic effect. The article contains a description of principles of correction of vital body functions, measures for removing toxic substances from the body and information on the main antidotes. Special attention is given to the most frequent types of intoxication (with organic acids, lye, naphazoline, paracetamol, snake poisons [viper bite]. The article lists stage of medical care rendering to children suffering from acute intoxication and presents prognosis and further management of pediatric patients suffering from such conditions.

    According to the best of our knowledge this is the first publication in medical literature about the acute intoxication with fenspiride. The two cases of a young female patients, intoxicated with Eurespal, were described. The orthostatic hypotonia with the blood pressure about 105-115/70 mm Hg in the horizontal position and 70-80/40 mm Hg in the sitting position was dominating. The heart rate was 100-110/min. when lying and 130-140/min. when sitting. The main symptoms were probably caused by inhibition of alpha1 adrenergic receptors. Main clinical manifestations make us reconsider the opinion about safety of fenspiride especially after acute intoxication.

    A subset of frequent users of emergency services are those who use the emergency department (ED) for acute alcohol intoxication. This population and their ED encounters have not been previously described. This was a retrospective, observational, cohort study of patients presenting to the ED for acute alcohol intoxication between 2012 and 2016. We collected all data from the electronic medical record. Frequent users for alcohol intoxication were defined as those with greater than 20 visits for acute intoxication without additional medical chief complaints in the previous 12 months. We used descriptive statistics to evaluate characteristics of frequent users for alcohol intoxication, as well as their ED encounters. We identified 32,121 patient encounters. Of those, 325 patients were defined as frequent users for alcohol intoxication, comprising 11,370 of the encounters during the study period. The median maximum number of encounters per person for alcohol intoxication in a one-year period was 47 encounters (range 20 to 169). Frequent users were older (47 years vs. 39 years), and more commonly male (86% vs. 71%). Frequent users for alcohol intoxication had higher rates of medical and psychiatric comorbidities including liver disease, chronic kidney disease, ischemic vascular disease, dementia, chronic obstructive pulmonary disease, history of traumatic brain injury, schizophrenia, and bipolar disorder. In this study, we identified a group of ED frequent users who use the ED for acute alcohol intoxication. This population had higher rates of medical and psychiatric comorbidities compared to non-frequent users.

    2002-07-01

    The object of this study was to investigate the genotoxic effect of acute overexposure to combustion products originating from coal or wood stoves in patients presenting with acute carbon monoxide intoxication. The authors analyzed the frequency of sister chromatid exchange and the carboxyhemoglobin concentration in 20 consecutive patients without a history of smoking or drug use who had been treated in the Emergency Care Unit of Istanbul Medical Faculty due to acute carbon monoxide intoxication. All of these cases were domestic accidents due to dysfunctioning coal or wood stoves. The results were compared with a control group of 20 nonsmoking, nondrug-using healthy individuals matched for age, sex, and absence of other chemical exposure. It was concluded that acute exposure to combustion products of wood or coal is genotoxic to DNA. Potential causes of genotoxicity include known mutagenic compounds present in coal or wood smoke and ash, oxygen radicals formed during combustion, as well as hypoxic and reperfusion injury mechanisms initiated by carbon monoxide intoxication.

  11. Acute interstitial nephritis with acetaminophen and alcohol intoxication

    Full Text Available Abstract Drug-induced acute interstitial nephritis (AIN represents a growing cause of renal failure in current medical practice. While antimicrobials and non-steroidal anti-inflammatory drugs are typically associated with drug-induced AIN, few reports have been made on the involvement of other analgesics. We report our experience in managing a 17-year-old female with AIN and subsequent renal injury following an acetaminophen overdose in conjunction with acute alcohol intoxication. It is well established that acetaminophen metabolism, particularly at high doses, produces reactive metabolites that may induce renal and hepatic toxicity. It is also plausible however, that such reactive species could instead alter renal peptide immunogenicity, thereby inducing AIN. In the following report, we review a possible mechanism for the acetaminophen-induced AIN observed in our patient and also discuss the potential involvement of acute alcohol ingestion in disease onset. The objective of our report is to increase awareness of healthcare professionals to the potential involvement of these commonly used agents in AIN pathogenesis.

  12. Lithium Intoxication

    Full Text Available Lithium has been commonly used for the treatment of several mood disorders particularly bipolar disorder in the last 60 years. Increased intake and decreased excretion of lithium are the main causes for the development of lithium intoxication. The influence of lithium intoxication on body is evaluated as two different groups; reversible or irreversible. Irreversible damage is usually related with the length of time passed as intoxicated. Acute lithium intoxication could occur when an overdose of lithium is received mistakenly or for the purpose of suicide. Patients may sometimes take an overdose of lithium for self-medication resulting in acute intoxication during chronic, while others could develop chronic lithium intoxication during a steady dose treatment due to a problem in excretion of drug. In such situations, it is crucial to be aware of risk factors, to recognize early clinical symptoms and to conduct a proper medical monitoring. In order to justify or exclude the diagnosis, quantitative evaluation of lithium in blood and toxicologic screening is necessary. Following the monitoring schedules strictly and urgent intervention in case of intoxication would definitely reduce mortality and sequela related with lithium intoxication. In this article, the etiology, frequency, definition, clinical features and treatment approaches to the lithium intoxication have been briefly reviewed.

  13. [Hospital morbidity and mortality of acute opiate intoxication].

    1990-09-22

    The records of 188 consecutive patients admitted for acute opiate intoxication were analyzed retrospectively to evaluate the morbidity and mortality of opiates. The most frequently used of these drugs were heroin (127 cases) and methadone (41 cases). In 79 cases the opiate was associated with another psychodepressant, usually benzodiazepines, alcohol or barbiturates. Forty-seven percent of the patients were admitted in deep coma, with respiratory arrest in almost every case. The complications observed in 49 patients were: aspiration of gastric contents (n = 24), rhabdomyolysis (n = 22), often associated with myocarditis (n = 13), pulmonary edema (n = 16), convulsions (n = 10), left ventricular dysfunction (n = 5) and lesions of the peripheral nervous system (n = 4). All patients survived, except one who died of cardiac arrest before admission. It is concluded that acute opiate intoxication treated in hospital has an excellent prognosis for life provided no cardiac arrest occurs prior to admission. One quarter of the patients require prolonged stay in an intensive care unit because of complications. The other patients, even when deeply comatose on admission, spend less than 1 day in hospital owing to the specific antagonist available.

    Severe acute lead intoxications are rare and are associated with accidental or purposeful ingestion. There were only few cases of severe to fatal poisonings reported in literature in children. We report a case of acute lead intoxication in a child with extremely high lead blood level of 20.4 micromol/L (422.7 microg/dL), who was treated with chelation and in whom significant organ dysfunction did not develop. Documented significant high level above 3.37 micromol/L (corresponding to 70 microg/dL) in this patient persisted for approximately 24 h. Adequate, single or combined chelatation therapy in early phase of acute lead poisoning is essential for the further patient's outcome.

    Traumatic and nontraumatic rhabdomyolysis can lead to acute renal failure (ARF), and acute alcohol intoxication can lead to multiple abnormalities of the renal tubules. We examined the effect of acute alcohol intoxication in a rat model of rhabdomyolysis and ARF. Intravenous injections of 5 g/kg ethanol were given to rats over 3 h, followed by glycerol-induced rhabdomyolysis. Biochemical parameters, including blood urea nitrogen (BUN), creatinine (Cre), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and creatine phosphokinase (CPK), were measured before and after induction of rhabdomyolysis. Renal tissue injury score, renal tubular cell expression of E-cadherin, nuclear factor-κB (NF-κB), and inducible nitric oxide synthase (iNOS) were determined. Relative to rats in the vehicle group, rats in the glycerol-induced rhabdomyolysis group had significantly increased serum levels of BUN, Cre, GOT, GPT, and CPK, elevated renal tissue injury scores, increased expression of NF-κB and iNOS, and decreased expression of E-cadherin. Ethanol exacerbated all of these pathological responses. Our results suggest that acute alcohol intoxication exacerbates rhabdomyolysis-induced ARF through its pro-oxidant and inflammatory effects.

    Full Text Available Abstract Objective: To review the screening, diagnosis, evaluation, and treatment of intoxication by alcohol and other drugs in children and adolescents in the emergency scenario. Data source: This was a narrative literature review. Data summary: The detection of this problem in the emergency room can be a challenge, especially when its assessment is not standardized. The intentional and episodic use of large amounts of psychoactive substances by adolescents is a usual occurrence, and unintentional intoxication is more common in children younger than 12 years. The clinical picture in adolescents and children differs from that in adults and some particularities are important in the emergency scenario. After management of the acute condition, interventions targeting the adolescent at risk may be effective. Conclusion: The diagnosis and treatment of intoxication by alcohol and other drugs in adolescents and children in the emergency scenario requires a systematic evaluation of the use of these drugs. There are few specific treatments for intoxication, and the management comprehends support measures and management of related clinical complications.

    Full Text Available Unintentional drug intoxication is still a major cause of morbidity and mortality in young children. In order to study the epidemiological pattern of childhood drug poisoning in Golestan province, all cases diagnosed with poisoning from 1997 to 2002 in the only pediatric hospital in province were recruited. During this period 563 cases of poisoned children were hospitalized in Taleqani hospital, of these 305 cases were due to drug poisoning. Opium was responsible for more than half of the poisoning cases, and 91% of deaths, among drug intoxicated children. Metoclopramide, benzodiazepines, tricyclic antidepressants and anticonvulsants were among the other frequent causes of poisoning. Neurological symptoms were the most prominent symptoms of poisoning and more than 80% of cases showed some neurological symptoms. Mortality rate among the cases was 3.6% and of total of 11 deaths, 10 were poisoned with opium. About 61% of cases were hospitalized between 24-48 hrs. Most of the poisoning cases in young children were unintentional and in many cases, their parents played a critical role in their intoxication. This role specially is crucial in infants and children under one year of age. Parents in Golestan province use opium widely for symptomatic treatment of routine illnesses in their young children and overdose of opium may cause severe intoxication and even death of the child.

  2. Effects of topiramate and other anti-glutamatergic drugs on the acute intoxicating actions of ethanol in mice: modulation by genetic strain and stress

    2008-01-01

    Compounds with anti-glutamatergic properties currently in clinical use for various indications (e.g., Alzheimer's disease, epilepsy, psychosis, mood disorders) have potential utility as novel treatments for alcoholism. Enhanced sensitivity to certain acute intoxicating effects (ataxia, sedative) of alcohol may be one mechanism by which anti-glutamatergic drugs modulate alcohol use. We examined the effects of six compounds (memantine, dextromethorphan, haloperidol, lamotrigine, oxcarbazepine, topiramate) on sensitivity to acute intoxicating effects of ethanol (ataxia, hypothermia, sedation/hypnosis) in C57BL/6J mice. Analysis of topiramate was extended to determine the influence of genetic background (via comparison of the 129S1, BALB/cJ, C57BL/6J, DBA/2J inbred strains) and prior stress history (via chronic exposure of C57BL/6J to swim stress) on topiramate's effects on ethanol-induced sedation/hypnosis. Results showed that one N-methyl-D-aspartate receptor (NMDAR) antagonist, memantine, but not another, dextromethorphan, potentiated the ataxic but not hypothermic or sedative/hypnotic effects of ethanol. Haloperidol increased ethanol-induced ataxia and sedation/hypnosis to a similar extent as the prototypical NMDAR antagonist MK-801. Of the anticonvulsants tested, lamotrigine accentuated ethanol-induced sedation/hypnosis, while oxcarbazepine was without effect. Topiramate was without effect per se under baseline conditions in C57BL/6J, but had a synergistic effect with MK-801 on ethanol-induced sedation/hypnosis. Comparing inbred strains, topiramate was found to significantly potentiated ethanol's sedative/hypnotic effects in BALB/cJ, but not 129S1, C57BL/6J or DBA/2J strains. Topiramate also increased ethanol-induced sedation/hypnosis in C57BL/6J after exposure to chronic stress exposure. Current data demonstrate that, with the exception of MK-801 and haloperidol, the compounds tested had either no significant or assay-selective effects on sensitivity to acute

    Balance control when standing upright is a complex process requiring input from several partly independent mechanisms such as coordination, feedback and feedforward control, and adaptation. Acute alcohol intoxication from ethanol is recognized as a major contributor to accidental falls requiring medical care. This study aimed to investigate if intoxication at 0.06 and 0.10% blood alcohol concentration affected body alignment. Mean angular positions of the head, shoulder, hip, and knee were measured with 3D-motion analysis and compared with the ankle position in 25 healthy adults during standing with or without perturbations, and with eyes open or closed. Alcohol intoxication had significant effects on body alignment during perturbed and unperturbed stance, and on adaptation to perturbations. It induced a significantly more posterior alignment of the knees and shoulders, and a tendency for a more posterior and left deviated head alignment in perturbed stance than when sober. The impact of alcohol intoxication was most apparent on the knee alignment, where availability of visual information deteriorated the adaptation to perturbations. Thus, acute alcohol intoxication resulted in inadequate balance control strategies with increased postural rigidity and impaired adaptation to perturbations. These factors probably contribute to the increased risk of falling when intoxicated with alcohol.

  4. [Abuse, dependence and intoxication of substances].

    2015-09-01

    As for substance-related disorders, there were several differences between ICD-10 and DSM-IV, however, the concept of "dependence" had been essential for both criteria. DSM-5 published in 2013 had erased dependence. This confuses us. It is important to recognize dependence again. "Abuse" is the self-intake behavior of drug against the social norms. Repeated abuse results in dependence. Dependence is a state of loss of control against drug use due to craving. Abuse can produce "acute intoxication", and repeated abuse under dependence can produce "chronic intoxication". It is important to understand abuse, dependence and "intoxication" based on their relationship from the point of time course.

    2012-05-01

    Full Text Available Background: Acute opium intoxication is one of the most common causes of poisoning in children in Iran. Although most cases are accidental, traditional misuse of opium for symptomatic therapy of various childhood diseases also contributes to high rate of opium intoxication in Iran. Cases: Here, we report two cases of opium intoxication in infants resulted from transdermal application of opium on burned skin. To our knowledge this is the first case report of intoxication from transdermal misuse of opium. Conclusion: Health care providers should be aware about signs and symptoms of opium intoxication in children. Opium intoxication should be suspected in each child with history of a recent burn injury that presented with decreased level of consciousness.

    Ethanol (EtOH) intoxication inhibits glucose transport and decreases overall brain glucose metabolism; however, humans with long-term EtOH consumption were found to have a significant increase in [1- 11 C]-acetate uptake in the brain. The relationship between the cause and effect of [1- 11 C]-acetate kinetics and acute/chronic EtOH intoxication, however, is still unclear. [1- 11 C]-acetate positron emission tomography (PET) with dynamic measurement of K 1 and k 2 rate constants was used to investigate the changes in acetate metabolism in different brain regions of rats with acute or chronic EtOH intoxication. PET imaging demonstrated decreased [1- 11 C]-acetate uptake in rat brain with acute EtOH intoxication, but this increased with chronic EtOH intoxication. Tracer uptake rate constant K 1 and clearance rate constant k 2 were decreased in acutely intoxicated rats. No significant change was noted in K 1 and k 2 in chronic EtOH intoxication, although 6 of 7 brain regions showed slightly higher k 2 than baseline. These results indicate that acute EtOH intoxication accelerated acetate transport and metabolism in the rat brain, whereas chronic EtOH intoxication status showed no significant effect. In vivo PET study confirmed the modulatory role of EtOH, administered acutely or chronically, in [1- 11 C]-acetate kinetics and metabolism in the rat brain. Acute EtOH intoxication may inhibit the transport and metabolism of acetate in the brain, whereas chronic EtOH exposure may lead to the adaptation of the rat brain to EtOH in acetate utilization. [1- 11 C]-acetate PET imaging is a feasible approach to study the effect of EtOH on acetate metabolism in rat brain. Copyright © 2017 by the Research Society on Alcoholism.

    Full Text Available Abstract Introduction Acute intoxication with drugs of abuse in children is often only the tip of the iceberg, actually hiding chronic exposure. Analysis using non-conventional matrices such as hair can provide long-term information about exposure to recreational drugs. Case presentation We report the case of a one-month-old Caucasian boy admitted to our pediatric emergency unit with respiratory distress and neurological abnormalities. A routine urine test was positive for opiates, suggesting an acute opiate ingestion. No other drugs of misuse, such as cocaine, cannabis, amphetamines or derivatives, were detected in the baby's urine. Subsequently, hair samples from the baby and the parents were collected to evaluate the possibility of chronic exposure to drug misuse by segmental analysis. Opiates and cocaine metabolites were detected in hair samples from the baby boy and his parents. Conclusions In light of these and previous results, we recommend hair analysis in babies and children from risky environments to detect exposure to heroin and other drug misuse, which could provide the basis for specific social and health interventions.

    This paper reports results of an analysis of the association between alcohol intoxication and injection and sexual HIV risk behaviors among 557 Hispanic heroin and cocaine injectors, not in treatment, who were recruited in poor communities in Puerto Rico. Subjects were part of a longitudinal prevention-intervention study aimed at reducing drug use and HIV risk behaviors. Participants reported a high prevalence of co-occurring conditions, particularly symptoms of severe depression (52%) and severe anxiety (37%), measured by Beck's Depression Index and Beck's Anxiety Index, respectively. Alcohol intoxication during the last 30 days was reported by 18% of participants. Associations were found between alcohol intoxication and both injection and sexual risk behaviors. In the bivariate analysis, subjects reporting alcohol intoxication were more likely to inject three or more times per day, pool money to buy drugs, share needles, and share cotton. They were also significantly more likely to have a casual or paying sex partner and to have unprotected sex with these partners. After adjustment, sharing needles and cotton, having sex with a paying partner or casual partner, and exchanging sex for money or drugs were significantly related to alcohol intoxication. HIV prevention programs, to be effective, must address alcohol intoxication and its relation to injection and sexual risk behaviors as a central issue in HIV prevention among drug injectors.

    The objective was to describe the population utilizing a sobering center for public alcohol intoxication and compare between single-visit users, repeat users, and high users. We conducted a secondary analysis of 1,271 adults cared for in a sobering center from July 2014 to June 2015. We divided the population into three groups-single use (one visit), repeat users (two to five visits), and high (six or more) users-and evaluated demographics, lifetime health diagnoses utilizing the Elixhauser Comorbidity Index, rates of public service utilization including ambulance and emergency department, and related costs. The population was primarily male, middle-aged, and ethnically diverse. Compared to single-visit users (n = 869), repeat (n = 287) and high users (n = 115) were older, were more likely to be currently homeless, and had spent more time homeless. Repeat and high users had significantly higher rates of hypertension, liver disease, diabetes, depression, psychoses, and drug abuse diagnoses compared to single-visit users. In addition to sobering visits, utilization of ambulance and ED and related costs were significantly greater for the high users compared to repeat and single-visit users. From an overall heterogeneous population, more frequent utilizers of the sobering center, both high and repeat users compared to low users, had significantly greater prevalence of chronic disorders, service utilization, and homelessness. Findings indicate that a sobering center can have a prominent role in the care for those with acute alcohol intoxication, particularly those individuals with chronic public intoxication who are likewise homeless. Further longitudinal research could offer important insights as to the population served over time, investigating changes in utilization and efforts toward health and housing stabilization. © 2017 by the Society for Academic Emergency Medicine.

    Acute drug intoxication is a medical emergency considering its potential interference with vital functions. All 157 cases with drug overdose admitted to the emergency department of the "Inselspital" in Berne over 183 days between July 1989 and June 1990 were analyzed retrospectively. In the vast majority of cases heroin overdose was involved. In mixed poisonings with heroin mostly flunitrazepam and alcohol contributed to the clinical picture, less commonly cocaine. There were very few intoxications with cocaine alone. A practical approach to the management of patients with certain or suspected drug intoxication presenting with coma and depressed respiration is proposed. In the therapy of acute intoxications with opiates and benzodiazepines there are specific antagonists available. In contrast, therapy of cocaine overdose remains symptomatic. The medical complications of acute heroin and cocaine intoxications are discussed separately.

    Full Text Available Spontaneous bladder rupture is a rare condition that can be followed by an acute alcohol intoxication and can be associated with significant morbidity and mortality. We report a case diagnosed in a alcoholic young male who was admitted to our emergency room for epigastric pain. The case demonstrates the difficulties with diagnosis and the need for physicians who work in an emergency room to be aware of this condition.

    Full Text Available Introduction. ‘Body packer’ syndrome with severe intoxication or sudden death may happen in persons who smuggle drugs in their body cavities. In case of lethal outcome when carrying cocaine, it is important, but sometimes difficult to determine whether death was due to intoxication or due to other causes. Therefore, it is necessary not only to quantify cocaine and its metabolites in biological material, but also based on their distribution in body fluids and tissues to conclude whether it is acute intoxication. We described a well-documented case of fatal poisoning in a body packer and post mortem distribution of the drug in biological samples. Case report. A 26-year-old man was brought to hospital with no vital signs. Resuscitation measures started at once, but with no success. Autopsy revealed 66 packets of cocaine in his digestive tract, one of which was ruptured. Hyperemia of the most of all internal organs and pulmonary and brain edema were found. High concentrations of cocaine, its metabolites benzoylecgonine and ecgonine methyl ester, as well as cocaine adulteration levamisole were proven in the post mortem blood and tissues by liquid chromatography-mass spectrometry (LC-MC method with selective-ion monitoring. Conclusion. The ratio of cocaine and its metabolites concentrations in the brain and blood obtained by LC-MS method can be used for forensic confirmation of acute intoxication with cocaine.

    Acute fish liver intoxication, including hypervitaminosis A and hypervitaminosis D, may result from the ingestion of certain fish livers. The typical symptoms of hypervitaminosis A include nausea, headache, blurred vision, and cutaneous manifestations, such as flushing, vesicles formation, and desquamation. Hypervitaminosis D may result in hypercalcemia. We report a case of acute fish liver intoxication with systemic and cutaneous manifestations. A 63-year-old male presented to the clinic with generalized desquamation and multiple clear-fluid filled flaccid vesicles after eating approximately two fist-sized portions (about 300-400 g) of cooked seerfish (Scomberomorus spp.) liver. Laboratory examination showed a high serum level of vitamin A and D, and hypercalcemia. Fish liver consumption from particular fish may result in acute hypervitaminosis A and D. In patients with skin detachment or blister formation, headache, drowsiness, and other symptoms and signs consistent with hypervitaminosis A and/or hypercalcemia, a history of fish intake should be sought, and a serum level of vitamin A and D should be measured.

    While uncommon, ingestion of ethanol-based hand sanitizers by children may be associated with significant intoxication. We report the case of a 7-year-old with acute alcohol intoxication following hand sanitizer ingestion. Alcohol elimination in this patient followed zero-order kinetics with a clearance rate of 22.5 mg/kg/h, consistent with the limited pharmacokinetic information available for children who experience alcohol intoxication from more traditional sources.

  17. Effects of Acute Alcohol Intoxication on Empathic Neural Responses for Pain

    Directory of Open Access Journals (Sweden)

    Yang Hu

    2018-01-01

    Full Text Available The questions whether and how empathy for pain can be modulated by acute alcohol intoxication in the non-dependent population remain unanswered. To address these questions, a double-blind, placebo-controlled, within-subject study design was adopted in this study, in which healthy social drinkers were asked to complete a pain-judgment task using pictures depicting others' body parts in painful or non-painful situations during fMRI scanning, either under the influence of alcohol intoxication or placebo conditions. Empathic neural activity for pain was reduced by alcohol intoxication only in the dorsal anterior cingulate cortex (dACC. More interestingly, we observed that empathic neural activity for pain in the right anterior insula (rAI was significantly correlated with trait empathy only after alcohol intoxication, along with impaired functional connectivity between the rAI and the fronto-parietal attention network. Our results reveal that alcohol intoxication not only inhibits empathic neural responses for pain but also leads to trait empathy inflation, possibly via impaired top-down attentional control. These findings help to explain the neural mechanism underlying alcohol-related social problems.

  18. The effects of acute alcohol intoxication on the cognitive mechanisms underlying false facial recognition.

    Colloff, Melissa F; Flowe, Heather D

    2016-06-01

    False face recognition rates are sometimes higher when faces are learned while under the influence of alcohol. Alcohol myopia theory (AMT) proposes that acute alcohol intoxication during face learning causes people to attend to only the most salient features of a face, impairing the encoding of less salient facial features. Yet, there is currently no direct evidence to support this claim. Our objective was to test whether acute alcohol intoxication impairs face learning by causing subjects to attend to a salient (i.e., distinctive) facial feature over other facial features, as per AMT. We employed a balanced placebo design (N = 100). Subjects in the alcohol group were dosed to achieve a blood alcohol concentration (BAC) of 0.06 %, whereas the no alcohol group consumed tonic water. Alcohol expectancy was controlled. Subjects studied faces with or without a distinctive feature (e.g., scar, piercing). An old-new recognition test followed. Some of the test faces were "old" (i.e., previously studied), and some were "new" (i.e., not previously studied). We varied whether the new test faces had a previously studied distinctive feature versus other familiar characteristics. Intoxicated and sober recognition accuracy was comparable, but subjects in the alcohol group made more positive identifications overall compared to the no alcohol group. The results are not in keeping with AMT. Rather, a more general cognitive mechanism appears to underlie false face recognition in intoxicated subjects. Specifically, acute alcohol intoxication during face learning results in more liberal choosing, perhaps because of an increased reliance on familiarity.

    The incidence and clinical aspects of seizures remain to be elucidated in patients with acute pesticide intoxication. The present study included subjects who ingested pesticide with the intention of committing suicide and were treated at Soonchunhyang University Hospital (Cheonan, Korea) between January 2011 and December 2014. We analyzed the incidence and characterized the type and frequency of seizure, from the medical records of 464 patients with acute pesticide intoxication, according to the pesticide class. The effect of seizure on the clinical outcome was assessed. The incidence of seizure was 31.5% in patients who ingested glufosinate ammonium {2-amino-4-[hydroxyl (methyl) phosphinoyl] butyrate; ammonium DL-homoalanin-4-yl (methyl) phosphinate}, followed by those who ingested pyrethroid (5.9%) or glycine derivatives (5.4%). All of the seizures developed between 12 and 24 h of pesticide ingestion and had ceased by 72 h after seizure initiation, following treatment with antiseizure medication. Generalized tonic-clonic seizures were the most commonly observed (85.7% of the cases). Multivariable logistic regression analysis showed that the effect of seizure on mortality was not statistically significant. In conclusion, glufosinate ammonium herbicide is the most common seizurogenic pesticide class. Seizure itself was not a risk factor for mortality in patients with acute glufosinate ammonium intoxication.

    A paucity of corroborative psychological and psychiatric evidence may be inhibiting detection of drug intoxication suicides in the United States. We evaluated the relative importance of suicide notes and psychiatric history in the classification of suicide by drug intoxication versus firearm (gunshot wound) plus hanging/suffocation-the other two major, but overtly violent methods. This observational multilevel (individual/county), multivariable study employed a generalized linear mixed model (GLMM) to analyze pooled suicides and undetermined intent deaths, as possible suicides, among the population aged 15 years and older in the 17 states participating in the National Violent Death Reporting System throughout 2011-2013. The outcome measure was relative odds of suicide versus undetermined classification, adjusted for demographics, precipitating circumstances, and investigation characteristics. A suicide note, prior suicide attempt, or affective disorder was documented in less than one-third of suicides and one-quarter of undetermined deaths. The prevalence gaps were larger among drug intoxication cases than gunshot/hanging cases. The latter were more likely than intoxication cases to be classified as suicide versus undetermined manner of death (adjusted odds ratio [OR], 41.14; 95% CI, 34.43-49.15), as were cases documenting a suicide note (OR, 33.90; 95% CI, 26.11-44.05), prior suicide attempt (OR, 2.42; 95% CI, 2.11-2.77), or depression (OR, 1.61; 95% CI, 1.38 to 1.88), or bipolar disorder (OR, 1.41; 95% CI, 1.10-1.81). Stratification by mechanism/cause intensified the association between a note and suicide classification for intoxication cases (OR, 45.43; 95% CI, 31.06-66.58). Prior suicide attempt (OR, 2.64; 95% CI, 2.19-3.18) and depression (OR, 1.48; 95% CI, 1.17-1.87) were associated with suicide classification in intoxication but not gunshot/hanging cases. Without psychological/psychiatric evidence contributing to manner of death classification, suicide by

    Haloperidol decanoate is a typical antipsychotic drug used as maintenance therapy for schizophrenia and mood disorders formulated as an ester for intramuscular injection. Cases of oral haloperidol decanoate intoxications have not been described in literature. In this report, we present for the first time a case of an oral ingestion of haloperidol decanoate of a young woman who presented to the emergency department following an intentional oral ingestion of 1 ampoule of haloperidol decanoate 100mg. At presentation, she had a bilateral rest tremor of both hands and mild hypothermia. No other obvious signs of an intoxication were observed. She was treated with a single dose of activated charcoal and laxative and was admitted to the intensive care for rhythm monitoring and observation. During the night the QTc interval increased to 453ms, but stayed within the normal range. Haloperidol plasma levels increased as well, but also stayed within therapeutic ranges. These findings indicate that treatment with oral activated charcoal was sufficient to prevent any serious events. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Alcohol addiction and intoxication are major health problems worldwide. Acute alcohol intoxication is well reported in adults and adolescents but less frequently reported in children of younger ages. We report three anonymized cases of pediatric ethanol exposure and illustrate the different mechanisms of intoxication. In all cases, a focused history is the key to prompt diagnosis and timely management. Physicians should be aware of this potential poison in children presented with acute confusional or encephalopathic state. In contrast, neonates with ethanol intoxication may present with nonspecific gastrointestinal symptomatology. Urgent exclusion of sepsis, electrolyte imbalance, drug intoxication, and surgical abdominal condition is critical. Using these illustrated cases, we performed a narrative literature review on issues of exposure to ethanol-containing substances and ethanol intoxication in children. In conclusion, a high level of suspicion and interrogation on ethanol or substance use are essential particularly in the lactating mother for an accurate and timely diagnosis of ethanol intoxication to be made.

    It was reported that the tiron had good therapeutic effects on small animals with acute uranium intoxication. The tiron's therapeutic effects as a first aid on large animals (38 dogs) with acute uranium poisoning are reported in this paper. Indices reflecting its effect were as follows: excretion rate of uranium from the dogs, several appropriate biochemical tests, clinical manifestations, histo-pathological changes of kidney and liver, and also the mortality of dogs. The results showed that the tiron or a combination of tiron and NaHCO 3 has a good therapeutic effect as a first aid on the dogs receiving lethal dose of uranyl nitrate

    It is shown that the response of the endocrine system (iodine-absorbing and hormone-secreting fUnctions of the thyroid) as studied by the radioactive iodine test may be a reasonably versatile indicator of the response of the thyroid component of the endocrine system to acute intoxication of the organism. Trials of this test using seven chemical substances have confirmed that the radioiodine test is a sufficienty universal method to be used in setting sanitary and hygienic standards for permissible levels of chemical substances

    1999-01-01

    To analyse MR findings of various involving sites and the relation between such findings and clinical outcome, the authors retrospectively reviewed MR images of acute carbon monoxide intoxication. In 12 patients, MR images obtained from several hours to 12 days after acute carbon monoxide intoxication were reviewed. The images were analysed with regard to involved sites, symmetricity, signal intensity, and the presence or absence of hemorrhage, and the relationship between MR findings and clinical outcome; the presence of delayed encephalopathy was then determined. The globus pallidus(n=9), white matter(n=3), [centrum semiovale(n=2), periventricular white matter(n=1)] and gyrus(n=6) [inferior temporal gyrus(n=2), cingulate gyrus(n=1), precentral gyrus(n=1), hippocampal gyrus(n=1), parahippocampal gyrus(n=1)] were typically involved, and there was also involvenent of the corpus callosum(n=3), thalamus(n=2) and midbrain(n=2). All lesions of the globus pallidus, thalamus, midbrain and temporal lobe were bilaterally symmetric. In all these cases, subtle or prominent low signal intensity was seen on spin-echo T1WI, and high signal intensity on PDWI and T2WI. Some lesions of the globus pallidus(n=1), thalamus(n=1) and midbrain(n=1) were associated with hemorrhage, which occurred during the early subacute stage and was seen on high/low signal intensity T1/T2WI images. Acute cerebral(n=1) and cerebellar(n=1) infarctions were also seen. Cerebral white matter involvement correlated with poor clinical outcome, and in two cases, delayed encephalopathy developed. In these cases of acute carbon monoxide intoxication, the globus pallidus, white matter, cortex and hippocampus were frequently involved, and there was also involvement of various sites such as the corpus callosum, thalamus and midbrain. Lesions of the temporal lobe, thalamus and midbrain were bilaterally symmetric. The involvement of cerebral white matter and the presence of delayed encephalopathy can influence

    2017-05-01

    Full Text Available Purpose: Several criteria have been suggested to estimate the intoxication severity, yet so far no system of clinical criteria has been developed to determine the duration of hospitalisation. The forecast is linked to the influence of the extended corrected QT interval and GCS (Glasgow Coma Scale on the frequency of the developing acute pulmonary insufficiency and lethality. The average duration of hospital treatment is also crucial. First of all, it is determined by the intoxication severity and lasts from 3 to 26 days. The aim of this study is to develop an individual forecast about the duration of hospitalisation for patients suffering from acute exogenous intoxication with organophosphorus pesticides (OPP. Materials/Methods: The subjects are 160 patients. We use statistical regression analysis to study the significance of 5 of the most typical clinical indicators of organophosphorus intoxication on the duration of hospitalisation: type of conscience, presence of spasms, pulmonary oedema, shock and multi-organ insufficiency syndrome (MOIS. To forecast the treatment length, we obtain simplified mathematical expressions in the form of score estimates. Results: The significance of the clinical indicators “MOIS”, “conscience” and “spasm” has been confirmed. A forecast matrix that gives the opportunity to forecast the personal duration of hospital treatment for each patient has been built.

    To describe acute toxicity of recreational drugs including novel psychoactive substances. We included all cases presenting at the emergency department (ED) of the University Hospital of Basel, Switzerland, between October 2013 and September 2014 with acute toxicity due to self-reported recreational drug use or with symptoms/signs consistent with acute toxicity. Isolated ethanol intoxications were excluded. Intoxications were confirmed with immunoassays and liquid chromatography coupled with mass spectrometry (LC-MS/MS), which also detected novel psychoactive substances. Among the 47,767 attendances at the ED, 216 were directly related to acute toxicity of recreational drugs. The mean patient age was 31 years and 69% were male. Analytical drug confirmation was available in 180 cases. Most presentations were related to cocaine (36%), cannabis (31%), opioids (13%), 3,4-methylenedioxy-methamphetamine (MDMA, 9%), other amphetamines (7%), benzodiazepines (7%), and lysergic acid diethylamide (LSD, 5%). The substances most commonly detected analytically were cannabis (37%), cocaine (33%), opioids (29%), benzodiazepines (21%), and amphetamines including MDMA (13%). Notably, there were only two cases of novel psychoactive substances (2,5-dimethoxy-4-bromophenethylamine [2C-B] and pentylone). The most frequent symptoms were tachycardia (31%), anxiety (27%), nausea or vomiting (23%), and agitation (22%). Severe complications included myocardial infarction (2), psychosis (10), seizures (10), and 1 fatality. Most patients were discharged home (68%), 8% were admitted to intensive care and 9% were referred to psychiatric care. Medical problems related to illicit drugs mostly concerned cocaine and cannabis and mainly involved sympathomimetic toxicity and/or psychiatric disorders. ED presentations associated with novel psychoactive substances appeared to be relatively rare.

  13. Case report of acute vitamin D intoxication in an infant

    2014-01-01

    Full Text Available Introduction. Vitamin D intoxication represents a rare and potentially serious pathological condition caused by the excess of calcium and phosphorus. We are presenting an infant with vitamin D intoxication due to excessive daily administration, as well as therapeutic procedures that prevented its adverse effects. Case Outline. A 1.5-month-old female infant, born at term, exclusively breastfed and without any complaints and abnormalities of physical findings, was observed due to the data that during the preceding month, by her mother’s mistake, she had received about 200,000 IU of vitamin D3. Laboratory analyses showed a high serum level of 25(OHD (>400 nmol/L and calcium (2.72 mmol/L, lowered PTH (6.6 pg/ml and high urinary calcium/creatinine ratio (1.6, while other findings, including urotract ultrasonography image, were within normal limits. Treatment based on the discontinuation of vitamin D administration, infant’s forced water intake, as well as the application of 2-month prednisolone and 4-month phenobarbitone and furosemide, resulted in complete normalization of the laboratory indicators of vitamin D overdose, as well as the prevention of its adverse effects. Conclusion. By timely recognition and adequate treatment, including triple therapy with prednisolone, phenobarbitone and furosemide, adverse effects of acute vitamin D intoxication can be prevented.

    Acute or subacute bipallidal lesion, an uncommon radiological feature produced by metabolic disorders or poisoning, has never been attributed to ethylene glycol (EG) intoxication. This 50-year-old Afro-Caribbean alcoholic man had unexplained loss of consciousness. Blood tests showed osmolar gap. Drug screening was positive for EG at 6.06 mmol/l. Brain CT revealed bilateral pallidal haemorrhage. Pallidal haematoma, which could be related to deposition of oxalate crystals issued from EG metabolism, should lead to toxicological screening.

    Acute or subacute bipallidal lesion, an uncommon radiological feature produced by metabolic disorders or poisoning, has never been attributed to ethylene glycol (EG) intoxication. This 50-year-old Afro-Caribbean alcoholic man had unexplained loss of consciousness. Blood tests showed osmolar gap. Drug screening was positive for EG at 6.06 mmol/l. Brain CT revealed bilateral pallidal haemorrhage. Pallidal haematoma, which could be related to deposition of oxalate crystals issued from EG metabolism, should lead to toxicological screening.

    Over a 10-year period (1998-2007) all deaths in Sweden classified by forensic pathologists as fatal drug poisonings (N = 6894) were retrieved from a toxicology database (TOXBASE) belonging to the National Board of Forensic Medicine. The deaths were further classified as suicides N = 2288 (33%), undetermined N = 2260 (33%) and accidental N = 2346 (34%). The average age (± SD) of all victims was 49.1 ± 15.9 years and men 47.4 ± 15.6 years were 5-year younger than women 52.2 ± 15.8 years (p intoxications) was found in 22% of all poisoning deaths (p intoxication deaths were mostly ethanol-related (N = 976) and the mean and median blood-alcohol concentration (BAC) was 3.06 g/L and 3.10 g/L, respectively. The BAC decreased as the number of additional drugs in blood increased from 2.15 g/L with one drug to 1.25 g/L with 6 or more drugs. The mean (median) concentrations of non-alcohol drugs in mono-intoxication deaths were morphine (N = 93) 0.5mg/L (0.2mg/L), amphetamine (N = 39) 2.0mg/L (1.2mg/L), dextropropoxyphene (N = 33) 3.9 mg/L (2.9 mg/L), dihydro-propiomazine (N = 32) 1.6 mg/L (1.0mg/L) and 7-amino-flunitrazepam (N = 28), 0.4 mg/L (0.3mg/L). Elevated blood morphine in these poisoning deaths mostly reflected abuse of heroin as verified by finding 6-monoacetyl morphine (6-MAM) in the blood samples. When investigating drug poisoning deaths a comprehensive toxicological analysis is essential although the results do not reveal the extent of prior exposure to drugs or the development of pharmacological tolerance. The concentrations of drugs determined in post-mortem blood are one element in the case. The autopsy report, the police investigation, the findings at the scene and eye-witness statements should all be carefully considered when the cause and manner of death are determined.

    A toxicoproteomic study was performed on liver of rats treated with retrorsine (RTS), a representative hepatotoxic pyrrolizidine alkaloid at a toxic dose (140 mg/kg) known to cause severe acute hepatotoxicity. By comparing current data with our previous findings in mild liver lesions of rats treated with a lower dose of RTS, seven proteins and three toxicity pathways of vascular endothelial cell death, which was further verified by observed sinusoidal endothelial cell losses, were found uniquely associated with retrorsine-induced hepatotoxicity. This toxicoproteomic study of acute pyrrolizidine alkaloid intoxication lays a foundation for future investigation to delineate molecular mechanisms of pyrrolizidine alkaloid-induced hepatotoxicity.

    Full Text Available Abstract Lead is a significant occupational and environmental hazard. Battery industry is one of the settings related to lead intoxication. Published information on the use of oral chelating agents for the treatment of anaemia in the context of acute lead intoxication is limited. The patient was a 33 year immigrant female worker in a battery manufacture for 3 months. She complained for malaise that has been developed over the past two weeks. Pallor of skin and conjunctiva was the only sign found in physical examination. The blood test on admission revealed normochromic anaemia. Endoscopic investigation of the gastrointestinal system was negative for bleeding. The bone marrow biopsy was unrevealing. At baseline no attention has been paid to patient's occupational history. Afterwards the patient's occupational history has been re-evaluated and she has been screened for lead intoxication. The increased levels of the lead related biomarkers of exposure and effect confirmed the diagnosis. The patient received an oral chelating agent and an improvement in clinical picture, and levels of haematological and lead related biochemical parameters have been recorded. No side effect and no rebound effect were observed. This case report emphasizes the importance of the occupational history in the context of the differential diagnosis. Moreover, this report indicates that lead remains a significant occupational hazard especially in the small scale battery industry

METHODS: In the study is an investigation of outbreak. In the study used to face-to-face interviews with patients, parents of patients, menagers and teachers of school and the records of the health foundations and school and the laboratory works. RESULTS: Cases of acute pesticide intoxication first began appearing on 5 May 2008. During the course of the pesticide intoxication 51 cases were determined, though there were no fatalities. All cases are students of the Vali Saim COTUR RBPES. It has 1695 students. All cases, 35 (68.6% were females and 16 (31.4% males, and median age 11 (min=8, max=14. Intoxication was highest level as 84.3% in cases at the age of 11. The cause of the intoxication was agriculture medicine (pesticide contamination of the school’s drinking water. CONCLUSION: In order to prevent pesticide poisoning, it is necessary to be very careful with pesticide application especially in rural areas. Substances that are least toxic to human and environment, and are licenced and most effective to pests must be used, sensitive people, especially children, must be kept away. More attempts should be made for raising the awereness of zone managers and farmers in order to prevent intoxications. Even if there is important improvement in intoxication management, the most effective method is prevention of poisoning. [TAF Prev Med Bull 2009; 8(3.000: 199-206

We are reporting two cases of TMJ dislocation resulted from acute severe intoxication with pure propranolol (PPL for the first time. Bilateral TMJ dislocation happened in two patients who were admitted to intensive care unit with diagnosis of severe acute PPL toxicity. Clinical diagnosis of TMJ dislocation was obtained by physical examination. Successful reduction was performed for both patients without subsequent recurrence in two weeks following hospital discharge. Both of our subjects had no previous history of lower jaw dislocation. There was not any risk factor for dislocation such as convulsion during admission period, recent face trauma, or oral manipulation by the medical team. This study showed that TMJ dislocation may occur after severe acute PPL toxicity probably due to spastic contraction of the lateral pterygoid muscle. This is against previously mentioned hypothesis that stated masseteric muscles contraction as the main cause of a bilateral dislocated TMJ.Keywords: propranolol, toxicity, temporomandibular joint dislocation

    In the last time the alcohol consumption among children and adolescents is a big theme in all kind of media. The ethanol consumption among children and adolescents has risen during the last years, but also new hazardous drinking patterns like "binge-drinking" are increasing. These drinking episodes are responsible for many hospital presentations of children and adolescents with acute ethanol intoxication. This study is a retrospective analysis of 173 patients admitted to the university children hospital of Leipzig due to acute ethanol intoxication during the period 1998-2004. Investigated parameters were: socio-demographic factors, clinical presentation and management as well as quantity and type of alcohol. During the years 1998-2004 the rate of alcohol intoxicated patients in this study increased, from 1998-2003 at about 171.4%. Totally 173 patients with an average age of 14.5 years were admitted to the university children hospital. There were significantly more boys than girls. The mean blood alcohol concentration of these patients was 1.77%. Some of the patients had severe symptoms. 62 were unconscious, 2 were in coma and at least 3 patients had to be ventilated. A difference between socioeconomic groups could be observed by comparing the different school types. 44.8% of the patients went to the middle school. Furthermore 17 patients of this study had mental disorders or psychosocial problems and were therefore in psychological or psychiatric treatment. In this study a significant influence of social classes or psychosocial problems on alcohol consumption such as binge-drinking leading to acute ethanol intoxication could not be found. Alarming is the increasing number of ethanol intoxicated patients, the young age, the high measured blood ethanol concentrations and the severe symptoms of these patients. This is the reason why early and intensive prevention strategies are required.

    Tetramethylenedisulfotetramine (TETS) is a potent convulsant poison for which there is currently no approved antidote. The convulsant action of TETS is thought to be mediated by inhibition of type A gamma-aminobutyric acid receptor (GABA A R) function. We, therefore, investigated the effects of post-exposure administration of diazepam, a GABA A R positive allosteric modulator, on seizure activity, death and neuroinflammation in adult male Swiss mice injected with a lethal dose of TETS (0.15 mg/kg, ip). Administration of a high dose of diazepam (5 mg/kg, ip) immediately following the second clonic seizure (approximately 20 min post-TETS injection) effectively prevented progression to tonic seizures and death. However, this treatment did not prevent persistent reactive astrogliosis and microglial activation, as determined by GFAP and Iba-1 immunoreactivity and microglial cell morphology. Inhibition of soluble epoxide hydrolase (sEH) has been shown to exert potent anti-inflammatory effects and to increase survival in mice intoxicated with other GABA A R antagonists. The sEH inhibitor TUPS (1 mg/kg, ip) administered immediately after the second clonic seizure did not protect TETS-intoxicated animals from tonic seizures or death. Combined administration of diazepam (5 mg/kg, ip) and TUPS (1 mg/kg, ip, starting 1 h after diazepam and repeated every 24 h) prevented TETS-induced lethality and influenced signs of neuroinflammation in some brain regions. Significantly decreased microglial activation and enhanced reactive astrogliosis were observed in the hippocampus, with no changes in the cortex. Combining an agent that targets specific anti-inflammatory mechanisms with a traditional antiseizure drug may enhance treatment outcome in TETS intoxication. - Highlights: • Acute TETS intoxication causes delayed and persistent neuroinflammation. • Diazepam given post-TETS prevents lethal tonic seizures but not neuroinflammation. • A soluble epoxide hydrolase inhibitor alters

    Ethanol is commonly overused psychoactive substance in Poland and all around the world. It causes addiction, which occurs as a result of its chronic administration. One of the main symptoms of addiction is hunger due to psychoactive substance that prevents interruption of its adoption and contributes to relapse drinking. Acute poisoning with ethyl alcohol and alcohol withdrawal syndrome are diseases causing a potential danger to life. The prevalence of use and abuse of alcoholic beverages is a potential risk, causing health problems, including permanent damage of the central and peripheral nervous system and socio-economic problems. The aim of this study is to analyze certain aspects of the socio-economic situation of the patients hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome in 2010. 299 patients history was evaluated, among which 161 were treated for acute intoxication with ethanol and 138 due to alcohol withdrawal syndrome. Objects of interest were elements of subjective tests including: marital status of patients, their education and professional activity and the problem of homelessness. The study group consisted of 299 patients in age from 16 to 77 years, hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome. It was found that the largest group consisted of patients remaining married (42.81%) and unmarried (30.43%). Alcohol abuse affects people of all levels of education. In the present study, most patients had a vocational education (37.79%) and medium (23.08%). Patients were analyzed in terms of economic activity, among which about 40% were unemployed. In the whole group more than 10% of those were homeless. Ethyl alcohol intoxication and alcohol withdrawal represents a significant hazard. As a result of reliance, patients lose control of alcohol consumption and they

    Full Text Available Lithium is frequently used as a mood stabilizer in patients with mood disorders. Lithium has a narrow therapeutic index and high toxicity. Predisposing factors for intoxication are advanced age, diet disturbances, comorbid medical conditions affecting heart, kidneys or central nervous system and polypharmacy. CASE REPORT: Here we present a case of a 74-year-old woman with a history of Parkinson’s disease, hypertension and bipolar disorder. She was using quetiapine, valsartan with hydrochlorothiazide and levodopa with carbidopa. She presented with altered mental status and muscle rigidity. The patient was admitted with acute lithium intoxication after her second dose of treatment. Blood lithium level increased to 3.58 mEq/L. The woman was hospitalized in the Internal Medicine Intensive Care Unit. With hydration, her symptoms resolved and her lithium level returned to normal after 118 hours. CONCLUSIONS: Prescribing physicians and emergency room physicians should be aware of conditions which may cause a decreased threshold for intoxication.

    Betel quid use and abuse is wide spread in Asia but the physiological basis of intoxication and addiction are unknown. In subjects naïve to the habit of betel quid intoxication, the psychological and physiological profile of intoxication has never been reported. We compared the effect of chewing gum or chewing betel quid, and subsequent betel quid intoxication, on psychological assessment, prospective time interval estimation, numerical and character digit span, computerized 2 choice tests and mental tasks such as reading and mathematics with concurrent monitoring of ECG, EEG and face temperature in healthy, non-sleep deprived, male subjects naïve to the habit of chewing betel quid. Betel quid intoxication, dose dependently induced tachycardia (max 30 bpm) and elevated face temperature (0.7°C) (Pbetel quid intoxication. Betel quid intoxication strongly influenced the psychological aspects of perception such as slowing of the prospective perception of passage of a 1 minute time interval in 8 subjects (Pbetel quid intoxication in 10 subjects. The prevalence of betel quid consumption across a range of social and work settings warrants greater investigation of this widespread but largely under researched drug.

Some viral infections, vaccines and neuroimmunologic disorders are the most common causes of AC. Opium poisoning is an unusual cause of this condition. Case presentation A 2-year-old girl was referred with loss of consciousness. She was ataxic just a few minutes after opium ingestion and after 1 hour, she became unconscious. We only found pinpoint pupils. After naloxone drip, her condition had been better but she was still obtunded and her urine was positive for opium products (morphine. MRI of the brain showed marked bilateral cerebellar swelling that respond to high-dose steroid dramatically. Conclusion This case shows that opium intoxication should be considered as a rare cause of acute cerebellitis in children.

    A case of lead exposure resulting from the accidental ingestion of a lead-containing solution is reported. Because of clinical management rapidly performed through chelation therapy by 2,3-dimercaptopropane sulfonate sodium and meso-2,3-dimercaptosuccinic acid, blood lead levels of this 51-year-old patient were moderate (412.9 μg/L) and no clinical symptoms were observed. Numerous blood and urine samples were collected for kinetic analysis of lead elimination. However, we report the first case in which hair samples were analyzed to determine the excretion level of lead after acute intoxication.

    γ-hydroxybutyrate (GHB) is a drug of abuse that causes euphoria, anxiolysis and hypnosis. The recent rise in the recreational intake of GHB, as well as its association with “drug rape”, has turned the attention to GHB in acute hospital settings. Acutely admitted GHB intoxicated patients may display...... available. As a basis for understanding the clinical features of GHB intoxication and abuse, we here review the pharmacological and neurophysiological knowledge about GHB, which stems from decades of clinical and basic GHB research. Also, we discuss the latest discoveries in the quest for distinct GHB...... receptors in the brain, and their possible implications for future therapies of GHB abuse....

    Full Text Available Purpose: Poisoning with drugs occupies a leading position among the causes of acute intoxications. Etiological distribution of medicated poisoning in different countries, even if they are adjacent, is different. In the most studies it was reported that the highest incidence of poisoning is with benzodiazepines or other psychoactive drugs. A retrospective analysis of acute poisoning with benzodiazepines and other hypnotic drugs in the Varna region for 25 years period – from 1991 to 2015 was carried out. Material and Methods: The number of patients who received hospital treatment after poisoning with benzodiazepines is 1741, and those with other hypnotics is 293, representing respectively 26.37% and 4.44% of all drug intoxications. Results: The share of poisoning with benzodiazepines and hypnotics compared to all acute intoxications is 11.66%. They are more common in women – 1566 (77%. Men are 468 (23%, the ratio of men to women was 3.34:1. The largest number of intoxications is in the age group up to 24 years - 1123 (55.2%, and only 4.1% of patients over 60 years. Intentional suicide attempts are 1896 (93.2%. Death is registered in 8 (0.4% patients.

    Sterile abscess formation in the dog is accompanied by a large increase in output of urinary nitrogen and also by a small but definite increase in the blood non-protein nitrogen. All this nitrogenous material of course is derived from body protein injury and autolysis. Septic inflammation in the dog (pleurisy, pneumonia, peritonitis, etc.) likewise shows a distinct rise in the blood non-protein nitrogen. This rise is not often so great as that frequently observed in the intoxication of intestinal obstruction. Many acute infections in man (septicemia, peritonitis, pneumonia, etc.) show a definite rise in the non-protein nitrogen and urea nitrogen of the blood; some cases show a very great rise above normal (over 100 mg. of non-protein nitrogen per 100 cc. of blood). There may be no anatomical change in the kidney beyond the familiar picture of cloudy swelling. This does not exclude the possibility of some transient functional derangement of the kidney epithelium. Certain obscure intoxications in man may show a considerable rise in the non-protein nitrogen of the blood, indicating a large amount of protein disintegration. These findings must be taken into account in any clinical analysis and interpretation of high non-protein nitrogen of the blood in pathological conditions.

    In current societies, the risk of toxic liver damage has markedly increased. The aim of the present work was to carry out further research into the mechanism(s) of liver mitochondrial damage induced by acute (0.8 g/kg body weight, single injection) or chronic (1.6 g/ kg body weight, 30 days, biweekly injections) carbon tetrachloride – induced intoxication and to evaluate the hepatoprotective potential of the antioxidant, melatonin, as well as succinate and cranberry flavonoids in rats. Acute intoxication resulted in considerable impairment of mitochondrial respiratory parameters in the liver. The activity of mitochondrial succinate dehydrogenase (complex II) decreased (by 25%, p 4 displayed obvious irreversible impairments. Long-term melatonin administration (10 mg/kg, 30 days, daily) to chronically intoxicated rats diminished the toxic effects of CCl 4 , reducing elevated plasma activities of alanine aminotransferase and aspartate aminotransferase and bilirubin concentration, prevented accumulation of membrane lipid peroxidation products in rat liver and resulted in apparent preservation of the mitochondrial ultrastructure. The treatment of the animals by the complex of melatonin (10 mg/kg) plus succinate (50 mg/kg) plus cranberry flavonoids (7 mg/kg) was even more effective in prevention of toxic liver injury and liver mitochondria damage. Highlights: ► After 30-day chronic CCl 4 intoxication mitochondria displayed considerable changes. ► The functional parameters of mitochondria were similar to the control values. ► Melatonin + succinate + flavonoids prevented mitochondrial ultrastructure damage. ► The above complex enhanced regenerative processes in the liver.

  1. Impairment of autophagy: From hereditary disorder to drug intoxication

    At first, the molecular mechanism of autophagy was unveiled in a unicellular organism Saccharomyces cerevisiae (budding yeast), followed by the discovery that the basic mechanism of autophagy is conserved in multicellular organisms including mammals. Although autophagy was considered to be a non-selective bulk protein degradation system to recycle amino acids during periods of nutrient starvation, it is also believed to be an essential mechanism for the selective elimination of proteins/organelles that are damaged under pathological conditions. Research advances made using autophagy-deficient animals have revealed that impairments of autophagy often underlie the pathogenesis of hereditary disorders such as Danon, Parkinson's, Alzheimer's, and Huntington's diseases, and amyotrophic lateral sclerosis. On the other hand, there are many reports that drugs and toxicants, including arsenic, cadmium, paraquat, methamphetamine, and ethanol, induce autophagy during the development of their toxicity on many organs including heart, brain, lung, kidney, and liver. Although the question as to whether autophagic machinery is involved in the execution of cell death or not remains controversial, the current view of the role of autophagy during cell/tissue injury is that it is an important, often essential, cytoprotective reaction; disturbances in cytoprotective autophagy aggravate cell/tissue injuries. The purpose of this review is to provide (1) a gross summarization of autophagy processes, which are becoming more important in the field of toxicology, and (2) examples of important studies reporting the involvement of perturbations in autophagy in cell/tissue injuries caused by acute as well as chronic intoxication

    Full Text Available Acute agitation occurs in a variety of medical and psychiatric conditions, and the management of agitated, abusive, or violent patients is a common problem in the emergency department. Rapid control of potentially dangerous behaviors by physical restraint and pharmacologic tranquillization is crucial to ensure the safety of the patient and health-care personnel and to allow diagnostic procedures and treatment of the underlying condition. The purpose of this article (the second in a 2-part series is to review published data on the efficacy and safety of antipsychotic medications currently available for managing situations of this type. Arrhythmias caused by QT-prolonging drugs occur infrequently, and multiple factors are often involved, including concomitant use of other drugs affecting the same pathway (most antipsychotic drugs prolong the QT interval by blocking potassium IKr current in HERG channels of myocardial cells, electrolyte disorders and, possibly, genetic predisposition. Judicious use of typical antipsychotics (mainly haloperidol and benzodiazepines (mainly lorazepam, given intramuscularly alone or in combination, has proved to be safe and effective for controlling acute motor agitation related to psychiatric illness; cocaine, methamphetamine, and ethanol toxicity; ethanol withdrawal; and other factors. They are still widely used and are particularly useful when limited data are available on the patient’s history of cardiovascular disease, current use of medication, and/or the likelihood of illicit drug or alcohol intoxication; when the diagnosis involves medical comorbidity or intoxication; or when there is no specific treatment (e.g., personality disorders, learning disabilities, mental retardation, organic brain damage. If rapid tranquillization is necessary before a formal diagnosis can be made and there are uncertainties regarding the patient’s medical history, lorazepam is often considered the first-line drug of choice.

    Background: Metformin is a biguanide antihyperglycemic agent that decreases insulin resistance. It is removed through renal mechanisms and its clearance is reduced in renal failure. Metformin ingestion should always be considered in the differential diagnosis of any patient with metabolic acidosis and increased lactate level. Hemodialysis and continuous veno-venous hemofiltration (CVVH) are both efficient methods to treat metformin intoxication and correct metabolic abnormalities. Patient 1: A 63-year-old man with type 2 diabetes mellitus presented to emergency department (ED) of Lodi (Italy) for dyspnea. He also reported having diarrhea for 10 days. Initial investigations revealed metabolic acidosis with hyperlactatemia and hypoglycemia (54 mg/dL), metformin concentration was 41 μg/mL (normal value <4 μg/mL). His hemodynamic condition became rapidly unstable and hypotension worsened despite CVVH being performed. Death occurred in 24 h. Patient 2: A 76-year-old man with type 2 diabetes mellitus presented to ED of Lodi for dyspnea. He referred a recent surgery amputation of the left foot's fifth phalanx for osteomyelitis, in levofloxacin therapy. Initial investigations revealed metabolic acidosis with hyperlactatemia and severe hypoglycemia (20 mg/dL). Two hemodialysis sessions were performed with complete normalization of the serum concentration of metformin. In our two cases the genesis of metformin intoxication was clear, powered by acute renal failure, but less obvious was the etiology of acute renal damage responsible for metformin accumulation. Damage due to renal hypoperfusion or the direct toxic effect of metformin should be considered. Additionally, for the second patient, we can also hypothesize that interstitial nephritis was exacerbated by levofloxacin.

  5. Neurological aspects of lead intoxication

    This study gives a survey over the medical and scientific literature on lead intoxications, which were published until 1979. Neurologic aspects are of particular interest. At present dramatic cases of lead intoxications occur only rarely. However, there are numerous studies about cases of chronical, partly subclinical intoxications. This chronical type of lead intoxication can become manifest clinically as relatively vague symptoms, for example vertigos, insomnia, headaches and weakness. Contrary to this, serious encephalopathies, even with fatal outcome, and polyneuropathies with typical paresis of the radial nerve are preferably observed in acute lead intoxications. Besides the numerous sources of intoxication, also the different opinions found in literature are discussed, concerning the effects of lead on the human body. The fact that there are differing opinions about the limiting value of the blood-lead level at which intoxication symptoms have to be expected, becomes apparent when the determined blood-lead level values are compared and evaluated. Besides the description of general intoxication effects, the discussion of the neurologic aspects found in literature - not only those concerning the central, but also the peripheral system - are preferably concerned. Reports about neuropsychical alterations due to lead exposure, which are mainly found in children, supplement the numerous descriptions of the macroscopic and microscopic alterations of the nervous system provoked by lead. Finally the therapeutic and prophylactic measures given in the literature are discussed.

    Full Text Available Abstract Introduction Most trauma patients are drunk at the time of injury. Up to 2% of traumatized patients develop sepsis, which considerably increases their mortality. Inadequate wound healing of the colonic repair can lead to postoperative complications such as leakage and sepsis. Objective To assess the effects of acute alcohol intoxication on colonic anastomosis wound healing in septic rats. Methods Thirty six Wistar rats were allocated into two groups: S (induction of sepsis and AS (alcohol intake before sepsis induction. A colonic anastomosis was performed in all groups. After 1, 3 or 7 days the animals were killed. Weight variations, mortality rate, histopathology and tensile breaking strength of the colonic anastomosis were evaluated. Results There was an overall mortality of 4 animals (11.1%, three in the group AS (16.6% and one in the S group (5.5%. Weight loss occurred in all groups. The colon anastomosis of the AS group didn’t gain strength from the first to the seventh postoperative day. On the histopathological analysis there were no differences in the deposition of collagen or fibroblasts between the groups AS and S. Conclusion Alcohol intake increased the mortality rate three times in septic animals. Acute alcohol intoxication delays the acquisition of tensile strength of colonic anastomosis in septic rats. Therefore, acute alcohol intoxication before sepsis leads to worse prognosis in animal models of the abdominal trauma patients.

    The use of cannabis as both a therapeutic agent and recreational drug is common, and its availability is increasing as a result of legalization in many countries. Among older children, the manifestations of cannabis intoxication are numerous and include both neurological and systemic manifestations that are frequently non-specific. There have been only a few reports detailing cannabis intoxication in infants and toddlers. We describe three infants who presented to the emergency department with encephalopathic signs without prominent systemic manifestations. During the initial interview of caregivers, no history of exposure to neurotoxic agents was obtained. All three patients were subsequently diagnosed with cannabis intoxication based on urine toxic screens for delta-9-tetrahydrocannabinol (THC). The infants recovered with supportive care that included fluids and monitoring. The non-specific symptomatology of cannabis intoxication in infants together with the wide differential for unexplained acute onset encephalopathy may delay diagnosis and lead to inappropriate procedures and interventions such as antimicrobial treatments and imaging studies. Healthcare personnel of emergency rooms, urgent care centers, and general clinics should be aware of the potential risk of cannabis ingestion in young infants. A thorough medical history and toxic screen are warranted in all infants with unexplained decreased sensorium.

    Betel quid use and abuse is wide spread in Asia but the physiological basis of intoxication and addiction are unknown. In subjects naïve to the habit of betel quid intoxication, the psychological and physiological profile of intoxication has never been reported. We compared the effect of chewing gum or chewing betel quid, and subsequent betel quid intoxication, on psychological assessment, prospective time interval estimation, numerical and character digit span, computerized 2 choice tests and mental tasks such as reading and mathematics with concurrent monitoring of ECG, EEG and face temperature in healthy, non-sleep deprived, male subjects naïve to the habit of chewing betel quid. Betel quid intoxication, dose dependently induced tachycardia (max 30 bpm) and elevated face temperature (0.7°C) (Pchewing gum (max 12 bpm and 0.3°C) in 12 subjects. Gross behavioral indices of working memory such as numerical or character digit span in 8 subjects, or simple visual-motor performance such as reaction speed or accuracy in a two choice scenario in 8 subjects were not affected by betel quid intoxication. Betel quid intoxication strongly influenced the psychological aspects of perception such as slowing of the prospective perception of passage of a 1 minute time interval in 8 subjects (Pincreased arousal (Pchewing gum by betel quid intoxication in 10 subjects. The prevalence of betel quid consumption across a range of social and work settings warrants greater investigation of this widespread but largely under researched drug. PMID:21909371

    Full Text Available Introduction: In some intoxicated patients, cerebrospinal fluid (CSF is examined due to the prolonged loss of consciousness, focal neurologic findings, and fever of unknown origin. We aimed to evaluate the probable relationship between the different toxicity causes and the CSF indices in poisoned patients and determine if they could predict the patients’ outcome. Methods: All patients who had been admitted to the toxicology intensive care unit of Loghman-Hakim hospital between March 2006 and March 2011 and had undergone lumbar puncture (LP were included into this retrospective study. The patients’ demographic data and results of CSF evaluation (level of glucose, lactate dehydrogenase, protein, and white blood cells in CSF fluid were evaluated. The data was analyzed using SPSS software version 17. Results: A total of 111 patients were evaluated. Mean age of the patients was 37±15 years. Thirteen (11.7% had deceased. No relation was found between the cause of poisoning (medication involved and the changes in CSF indices. A statistically significant difference was found between the survivors and non-survivors in terms of CSF protein, LDH, and WBC. However, such a difference was not detected between these two groups regarding CSF glucose. Conclusion: In intoxicated patients with prolonged decreased level of consciousness or prolonged fever, early evaluation of CSF can help early diagnosis of complications such as meningitis and prompt treatment. Also, high level of protein, LDH, and WBC in the CSF can predict higher mortality rates in these patients.

The aim of the present work was to carry out further research into the mechanism(s) of liver mitochondrial damage induced by acute (0.8 g/kg body weight, single injection) or chronic (1.6 g/ kg body weight, 30 days, biweekly injections) carbon tetrachloride – induced intoxication and to evaluate the hepatoprotective potential of the antioxidant, melatonin, as well as succinate and cranberry flavonoids in rats. Acute intoxication resulted in considerable impairment of mitochondrial respiratory parameters in the liver. The activity of mitochondrial succinate dehydrogenase (complex II) decreased (by 25%, p < 0.05). Short-term melatonin treatment (10 mg/kg, three times) of rats did not reduce the degree of toxic mitochondrial dysfunction but decreased the enhanced NO production. After 30-day chronic intoxication, no significant change in the respiratory activity of liver mitochondria was observed, despite marked changes in the redox-balance of mitochondria. The activities of the mitochondrial enzymes, succinate dehydrogenase and glutathione peroxidase, as well as that of cytoplasmic catalase in liver cells were inhibited significantly. Mitochondria isolated from the livers of the rats chronically treated with CCl{sub 4} displayed obvious irreversible impairments. Long-term melatonin administration (10 mg/kg, 30 days, daily) to chronically intoxicated rats diminished the toxic effects of CCl{sub 4}, reducing elevated plasma activities of alanine aminotransferase and aspartate aminotransferase and bilirubin concentration, prevented accumulation of membrane lipid peroxidation products in rat liver and resulted in apparent preservation of the mitochondrial ultrastructure. The treatment of the animals by the complex of melatonin (10 mg/kg) plus succinate (50 mg/kg) plus cranberry flavonoids (7 mg/kg) was even more effective in prevention of toxic liver injury and liver mitochondria damage

    The changes of urine porphyrin content are studied in albino rats with experimental acute uranium intoxication (single intraperitoneal injection of uranyl acetate, 7.0 mg/kg bodyweight). The observations have been conducted in the course of 10 days. It is found that both in control and in treated animals the urine is practically free from uroporphyrin. The delta-aminolevulinic acid content varied within broad limits, but the differences from control animals is statistically insignificant. A significant increase in urine porphobilinogen is observed, with a maximum on the second and eigth day after treatment. Coproporphyrin was significantly reduced since the first day of the experiment. All these changes seem to be due to impaired excretory capacity of the kidneys against the background of developing nitrogen retention and overall intoxication of the animal organism. Another possible explanation is that uranyl acetate inhibits some enzymes responsible for the transformation of porphobilinogen into uroporphyrin. (Ch.K.)

    The protective potential of diethyl barbituric acid sodium salt is studied, in comparison with that of acetazolamide, on kidneys under acute uranium intoxication. Experiments involved rats given intraperitoneal injections with uranyl acetate on 12 successive days up to a total dose of 0.5, 2.0 or 7.0 mg/kg. The resulting effects are measured by chemical assays of serum and urine for alkaline and acid phosphatase and histochemical assays for phosphatase activities in kidneys, kinetics being followed over a 30-day period after total dose administration. Protection of kidneys from toxic uranium effects was found to be of about the same degree with sodium diethyl barbiturate as with acetazolamide. (A.B.)

    Bupropion, an amphetamine-like dual mechanism drug, is approved and increasingly used for the treatment of major depression, and its use is associated with a dose-dependent risk of epileptic seizures. Suicide attempts are frequent in major depression and often an overdose of the drugs available is ingested. Therefore, it is important to be aware of the clinical course, including EEG and neurological symptoms, as well as treatment and prognosis of bupropion intoxication. We report on the clinical and EEG course of a women who ingested 27 g of bupropion in a suicide attempt. Myoclonic seizures were followed by generalized tonic-clonic seizures and coma associated with EEG burst-suppression and brief tonic seizures. Active carbon and neuro-intensive care treatment, including respiratory support, were given. Within three days, the patient returned to a stable clinical condition with a mildly encephalopathic EEG. In conclusion, bupropion intoxication requires acute intensive care treatment and usually has a good prognosis, however, misinterpretation of the clinical and EEG presentation may lead to errors in management.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

    Full Text Available The purpose of this study was to evaluate the effectiveness of a succinic acid derivate, a substrate metabolic agent cytoflavin in patients with acute poisoning with synthetic psychoactive drugs.Materials and methods. A retrospective evaluation of effectiveness of a combined intensive care treatment protocol for 622 patients with acute narcotic poisoning (methadone and synthetic cannabinoids was carried out. All patients were divided into two groups. The main group (112 patients, median age 38.2±12.0 years included patients who, in addition to the basic treatment, received cytoflavin by intravenous drop infusion, 20–40 ml diluted in 400–500 ml of 10% glucose, for 5 days. Patients of the reference group (510 subjects, median age 37.6±14.1 years received treatment according to the «classical scheme». In addition to conventional examination, all patients underwent duplex scanning of cerebral vessels, examination of changes in the cerebral blood circulation and electroencephalogram findings. The severity of somatic disorders was assessed using criteria of the Glasgow coma scale. The severity of the asthenic syndrome was assessed according to the MFI-20 scale.Results. Compared to patients who received a standard therapy, patients of the main group had a significantly more rapid recovery from coma (by 1.5-fold: 23.5±3.1 days, versus 15.1±3.0 days, respectively, P0.05; the duration of psychotic disorders was shorter (by 1.8-fold: 15.5±4.2 hours vs 8.3±2.5 hours., respectively, P0.05, and the intensity of asthenic syndrome (by 2.8-fold: 64.1±3.3 rel. units vs 23.0±4,9 rel. units, respectively, P0.05 was also lower.Conclusion. Inclusion of cytoflavin in a protocol of a complex treatment of patients with synthetic drugs poisoning increased the effectiveness of the therapy. Data demonstrate that inclusion of the drug can be recommended for treatment of acute synthetic narcotic poisoning.

    Although the toxicity of lead and zinc to birds is widely recognized by veterinarians and bird owners, these metals are frequently found in the environments of pet and aviary birds, and intoxications are common. Clinical signs exhibited by intoxicated birds are often nonspecific, which makes early diagnosis difficult. Fortunately, lead and zinc analyses of whole blood and serum or plasma, respectively, are readily available and inexpensive; elevated concentrations can confirm intoxication. Once diagnosed, intoxication can be effectively treated by (1) preventing further exposure, (2) administering chelating drugs, and (3) providing symptomatic and supportive care.

  18. [Can one talk of benzodiazepine "drunkenness"? About acute benzodiazepine intoxication, without suicidal or mortiferous tendencies].

    2012-02-01

    When we refer to "drunkenness", more often than not, we think of alcohol or cannabis being the instigator rather than pharmacological drugs, even if outside the toxic origins, "drunkenness" may also occur without any substance intake: one can be drunk on love, poetry, music and even mania. Benzodiazepine "drunkenness" is not a classical notion in medicine. But the concept of addictology allows one to enlarge different approaches and to consider the relationship with psychoactive substances according to the same references. So, in a single fashion, between use and misuse, is it possible to resort to the same concepts for pharmacological drugs, including "drunkenness"? Any intake of a psychoactive substance, limited in time, which will take the consumer some time to recover from, can be called simple use, intoxication or drunkenness. Intoxication is rather a classical medical concept linked with poisoning, and hence the toxicological aspects prevail particularly through the concept of a toxidrome. However, little research has been done on "drunkenness" in other medical aspects, neither psychological aspects nor sociological aspects. If poisoning is defined as soon as a poison is introduced into the body, the intoxication arises after a threshold (that toxicology usually defines), but no means are available to measure the onset of the inebriation, neither any ingested amounts nor any toxic concentration in the body. It is hard to define "drunkenness" simply. At first, it is most often seen as a pathology in medicine, unlike in every day life. "Drunkenness" can be the result of physiological disturbances, notably through the effects of substances and can therefore be the manifestation of a cerebral dysfunction. Alternatively, it can arise from a variation of emotional or sensorial stimuli. If the feelings associated with drunkenness are positive and pleasant a repetition will occur in the search to reproduce enjoyable effects in reference to neurophysiological models

The activity of the glucose metabolism enzyme phosphoenolpyruvate carboxykinase (PEPCK, which had been diminished by the porphyrinogenic treatment, was restored by 45% when animals were pre-treated with Mel. Mel abolished the modest decrease in glucose 6-phospatase (G6Pase activity caused by AIA/DDC treatment. The oxidative status of lipids was attenuated by Mel treatment in homogenates by 47%, whereas no statistically significant AIA/DDC-induced increase in thiobarbituric acid reactive substances (TBARS was observed in microsomes after Mel pre-treatment. We hypothesize that Mel may be scavenging reactive species of oxygen (ROS that could be damaging lipids, PEPCK, G6Pase and ferrochelatase (FQ. Additionally, Mel administration resulted in the repression of the key enzyme ALA-S, and this could be due to an increase in glucose levels, which is known to inhibit ALA-S induction. The consequent decrease in levels of the heme precursors ALA and PBG had a beneficial effect on the drug-induced porphyria. The results obtained open the possibility of further research on the use of melatonin as a co-treatment option in acute porphyria.

    Full Text Available Selenium (Se is an essential trace element in human and animal nutrition. It is also widely utilized in industrial processes. Reports of acute selenium toxicity in humans are rare. We report a case of a 23-year-old female who consumed about 100 mL of liquid selenite broth and presented with severe nausea, vomiting, abdominal pain, hematemesis and acute renal failure (ARF. The serum selenium level was significantly increased. Gastro-duodenoscopy revealed severe corrosive gastritis. Renal biopsy showed features of acute tubular necrosis (ATN, affecting primarily the proximal tubules. The patient was managed with gastric lavage, blood transfusions, infusion of fresh frozen plasma (FFP and platelet concentrates and hemo-dialysis. The patient was discharged five weeks after admission and her renal functions reco-vered completely by eight weeks after admission. She continues to be on regular follow-up for any possible sequelae of mucosal corrosive damage. This case highlights a case of selenium intoxication from selenite broth resulting in ARF and corrosive gastritis. The recovery was complete.

    Acute and chronic intoxication with solvents is found both as an occupational hazard and as self-inflicted in addicts to solvent. Objective demonstration of such brain tissue changes is difficult with conventional imaging methods, and in most cases findings are negative. In a preliminary study, the brains of eight patients (aged 28-62 years) exposed to aggressive solvents for 1-27 years were examined with magnetic resonance imaging. All of the patients showed brain atrophy of varying extent, and seven of eight patients (all except the youngest and least exposed) had brain lesions that somewhat resembled dymyelinating changes (focal and confluent periventricular and deep white matter lesions, brain stem and cerebellar lesions); one patient showed cloudy, poorly defined lesions

    Full Text Available Opioid intoxications and overdose are associated with high rates of morbidity and mortality. Opioid overdose may occur in the setting of intravenous or intranasal heroin use, illicit use of diverted opioid medications, intentional or accidental misuse of prescription pain medications, or iatrogenic overdose. In this review, we focused on the epidemiology of illict opioid use in the United States and on the mechanism of action of opioid drugs. We also described the signs and symptoms, and diagnoses of intoxication and overdose. Lastly, we updated the reader about the most recent recommendations for treatment and prevention of opioid intoxications and overdose.

    Peter G Osborne

    Full Text Available Betel quid use and abuse is wide spread in Asia but the physiological basis of intoxication and addiction are unknown. In subjects naïve to the habit of betel quid intoxication, the psychological and physiological profile of intoxication has never been reported. We compared the effect of chewing gum or chewing betel quid, and subsequent betel quid intoxication, on psychological assessment, prospective time interval estimation, numerical and character digit span, computerized 2 choice tests and mental tasks such as reading and mathematics with concurrent monitoring of ECG, EEG and face temperature in healthy, non-sleep deprived, male subjects naïve to the habit of chewing betel quid. Betel quid intoxication, dose dependently induced tachycardia (max 30 bpm and elevated face temperature (0.7°C (P<0.001 above the effects observed in response to chewing gum (max 12 bpm and 0.3°C in 12 subjects. Gross behavioral indices of working memory such as numerical or character digit span in 8 subjects, or simple visual-motor performance such as reaction speed or accuracy in a two choice scenario in 8 subjects were not affected by betel quid intoxication. Betel quid intoxication strongly influenced the psychological aspects of perception such as slowing of the prospective perception of passage of a 1 minute time interval in 8 subjects (P<0.05 and perceived increased arousal (P<0.01 and perceived decreased ability to think (P<0.05 in 31 subjects. The EEG spectral profile recorded from mental states associated with open and closed eyes, and mental tasks such as reading and eyes closed mental arithmetic were significantly modified (P<0.05 relative to chewing gum by betel quid intoxication in 10 subjects. The prevalence of betel quid consumption across a range of social and work settings warrants greater investigation of this widespread but largely under researched drug.

    When in cases of patients with severe intoxication aspiration is suspected clinically, an X-ray image of the thorax is made in order to prevent that atelectases or inflammatory pulmonary infiltrations remain undetected, in addition, an X-ray image of the abdomen should be made in each in which the swallowed preparation has not been identified, because our investigations have proved that any drugs of any kind with an absorption coefficient above 0.23 are radiologically detectable, when the resorption process is not finished yet. In shadow-producing pharmaceuticals these abdominal X-ray images allow not only the examination and supervision of the toxic resorption of an enterally taken preparation, but also the possible identification of the type the drug belongs to. Moreover, information about quantity, resorption, and localisation of the tablets being somewhere in the gastrointestinal tract can be obtained. (orig.) [de

    Full Text Available The paper presents the clinical results of a double-blind, randomized, placebo-controlled multicenter phase III study evaluating the clinical efficacy and safety of Ingavirin® capsules 30 mg at a daily dose of 60 mg for the treatment of influenza and other acute respiratory viral infections (ARVI in 7–12-year-old children.The study included 310 children of both sexes. The study participants took Ingavirin® 60 mg/day or placebo for 5 days. The drug was shown to be effective in normalizing temperature and alleviating intoxication and catarrhal syndromes just at day 3 of therapy. Ingavirin® was demonstrated to considerably reduce the risk of bacterial complications of ARVI/influenza, which require antibiotic therapy, which is important for clinical use in children. This clinical trial has shown the high safety and tolerance of the drug. Ingavirin® contributes to accelerated virus elimination, shorter disease duration, and lower risk of complications.

    Full Text Available Cocaine is a commonly abused illicit drug that causes significant morbidity and mortality. The most severe and common complications are seizures, ischemic strokes, myocardial infarction, and acute liver injury. Here, we demonstrated that acute cocaine intoxication promoted seizure along with acute liver damage in mice, with intense inflammatory infiltrate. Considering the protective role of the endocannabinoid system against cell toxicity, we hypothesized that treatment with an anandamide hydrolysis inhibitor, URB597, or with a phytocannabinoid, cannabidiol (CBD, protects against cocaine toxicity. URB597 (1.0 mg/kg abolished cocaine-induced seizure, yet it did not protect against acute liver injury. Using confocal liver intravital microscopy, we observed that CBD (30 mg/kg reduced acute liver inflammation and damage induced by cocaine and prevented associated seizure. Additionally, we showed that previous liver damage induced by another hepatotoxic drug (acetaminophen increased seizure and lethality induced by cocaine intoxication, linking hepatotoxicity to seizure dynamics. These findings suggest that activation of cannabinoid system may have protective actions on both liver and brain induced by cocaine, minimizing inflammatory injury promoted by cocaine, supporting its further clinical application in the treatment of cocaine abuse.

    Prolonged exposure to gamma-hydroxybutyric acid (GHB) would cause drug intoxication in which impaired cognitive function results from enhanced hippocampal oxidative stress may serve as a major symptom in this deficiency. Considering melatonin possesses significant anti-oxidative efficacy, this study aimed to determine whether melatonin would successfully promote the nuclear factor erythroid 2-related factor 2 and antioxidant responsive element (Nrf2-ARE) signaling, depress oxidative stress, and rescue hippocampal bioenergetics and cognitive function following drug intoxication injury. Adolescent rats subjected to 10 days of GHB were received melatonin at doses of either 10 or 100 mg/kg. Time-of-flight secondary ion mass spectrometry, biochemical assay, quantitative histochemistry, [ 14 C]-2-deoxyglucose analysis, together with Morris water maze were employed to detect the molecular signaling, oxidative status, bioenergetic level, as well as the cognitive performances, respectively. Results indicated that in GHB-intoxicated rats, enhanced oxidative stress, increased cholesterol level, and decreased anti-oxidative enzymes activities were detected in hippocampal regions. Intense oxidative stress paralleled well with reduced bioenergetics and poor performance in behavioral testing. However, in rats treated with melatonin following GHB intoxication, all above parameters and cognitive function were gradually returned to nearly normal levels. Melatonin also remarkably promoted the translocation of Nrf2 from cytoplasm to nucleus in a dose-dependent manner, thereby increased the Nrf2-ARE signaling-related downstream anti-oxidative enzymes activities. As melatonin effectively rescues hippocampal bioenergetics through depressing the oxidative stress by promoting Nrf2-ARE molecular machinery, this study thus highlights for the first time that clinical use of melatonin may serve as a therapeutic strategy to improve the cognitive function in unsuspecting victims suffered from

  10. Primary Screening for Proteins Differentially Expressed in the Myocardium of a Rat Model of Acute Methamphetamine Intoxication

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The mechanism of myocardial injury induced by the cardiovascular toxicity of methamphetamine (MA has been shown to depend on alterations in myocardial proteins caused by MA. Primary screening of the expression of myocardial proteins in a rat model of MA intoxication was achieved by combining two-dimensional electrophoresis and mass spectrometry analyses, which revealed a total of 100 differentially expressed proteins. Of these, 13 displayed significantly altered expression. Moreover, Western blotting and real-time reverse transcription quantitative polymerase chain reaction analyses of several relative proteins demonstrated that acute MA intoxication lowers protein expression and mRNA transcription of aldehyde dehydrogenase-2 and NADH dehydrogenase (ubiquinone 1 alpha subcomplex subunit 10. In contrast, MA intoxication elevated the protein expression and mRNA transcription of heat shock protein family B (small member 1. By combining behavioral assessments of experimental rat models with the histological and pathological changes evident in cardiomyocytes, a mechanism accounting for MA myocardial toxicity was suggested. MA alters the regulation of gene transcription and the subsequent expression of certain proteins that participate in myocardial respiration and in responding to oxidative stress, resulting in myocardial dysfunction and structural changes that affect the functioning of the cardiovascular system.

    Although, in the laboratory, most acute adverse effects of cocaine are dose-dependent and alcohol potentiates some of these effects, there are few observational studies, and scarce awareness that the risk of acute cocaine intoxication (ACI) can increase as the amounts of cocaine and alcohol consumed increase. Our objectives were to assess if the risk of ACI increases with the level cocaine use, both in chronic and binge use; and also to determine whether it increases when a cocaine binge is combined with binge drinking or with regular excessive drinking. Hypotheses were evaluated using logistic regression and case-crossover analyses in a sample of 720 young regular cocaine users who did not regularly use heroin, recruited at drug scenes in 2004-2006. All data on ACI, predictor and confounding variables were obtained through a computer-assisted personal interview. The annual prevalence of ACI was 21%. In the last year 10.3% of the participants reported cocaine binges (≥ 0.5 g in 4 h). ACI risk increased considerably in the 4 h following a cocaine binge (odds ratio = 34.6; 95% confidence interval 11.5-170.8). Also, it increased with increases in the average level of cocaine used over a long period and when users regularly drank excessively. Finally, the results suggest that the high risk of ACI associated with cocaine binge may increase even more when combined with binge drinking. Awareness of the dose-dependent effect of cocaine on ACI risk, as well as the possible synergistic effect of alcohol, ought to be incorporated into preventive and care strategies. © 2012 Australasian Professional Society on Alcohol and other Drugs.

    Determining the manner of death in medicolegal death investigations can be difficult. The investigator relies on many facets of death investigation, including the circumstances of death and autopsy examination. A study was designed to analyze whether the intoxication status of the decedent could be used as another tool in death investigations. The intoxication status of violent (nonoverdose or poisoning) suicides and homicides was retrospectively reviewed and compared. A total of 625 deaths were identified, including 366 suicides and 259 homicides. Age, sex, cause of death, and intoxication status, including the specific drugs present, were analyzed. Gunshot wounds were the most common cause of death in both groups, with hanging being the second most common cause in suicides and sharp force injuries in homicides. Analysis found that although the overall intoxication status for suicides versus homicides did not differ significantly, certain drugs were more prevalent in one group over the other. Specifically, illicit drugs, that is, heroin, cocaine, and methamphetamine, were more likely to be present in homicides, whereas antidepressants or antipsychotics, benzodiazepines, and zolpidem were more common in suicides.

    Acute poisoning of chemical etiology is a significant global public health problem. The aim of this study was the analysis of the toxicoepidemiological structure of psychopharmacological drugs poisoning in Azerbaijan. We collected and analyzed the data on all cases of acute poisoning by psychopharmacological drugs (codes of categories T42/T43 ICD-10) undergoing inpatient treatment at the Center of Clinical Toxicology in Baku, Azerbaijan in 2009-2016. The total number of patients with acute intoxication by psychopharmacological drugs was 3,413, which was 48.3% of all cases of poisoning by drugs, medicaments and biological substances (T36-T50). The predominance of women was registered in all age groups. 1114 patients or 32.6% were in 15-24 years old age group. The highest percentage of poisonings at category T42 of ICD-10 were benzodiazepine-type drugs (35.8%), and at category T43 - antipsychotic and neuroleptic drugs (19.2%). In the structure of benzodiazepine poisoning, the first and second ranked places belonged to phenazepam (71.0%) and clonazepam - 16.6%. In addition, another 120 cases (5.5%) of poisonings in the T42 cohort were caused by "Z drugs", which have similar therapeutic effect to benzodiazepines (zolpidem and zopiclone). Among the antipsychotic and neuroleptic poisonings, thioridazine, trifluoperazine, levomepromazine, chlorpromazine, and periciazine accounted for 91% of all cases of intoxication in this cohort. Barbiturates, in view of their toxicity and narrow range of therapeutic dosages, now lost their importance as antiepileptic and hypnotic drugs. Only 4.9% of all cases of poisoning, classified under category T42, was due to the use of barbiturates (mainly phenobarbital). Poisonings with iminostilbenes were presented by carbamazepine poisoning only. Most patients in this cohort received this anticonvulsant drug as prescribed by a doctor. Acute intoxications by tricyclic antidepressants in 91.5% were presented by cases of amitriptyline poisoning

    Atropa belladonna is a poisonous plant also called deadly nightshade. Its roots, leaves and fruits contain alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion with other berries. Atropa belladonna acute intoxication is a severe condition, it's should be considered in the presence of anti-cholinergic toxidrome, the differential diagnosis include other plants or psychoactive drugs containing atropine. The treatment is mainly symptomatic including gastrointestinal decontamination with activated charcoal. In severe cases, physostigmine can be used as an antidote. We report the case of 11 year old girl with Atropa belladonna poisoning which was administrated in a therapeutic purpose as a remedy to jaundice. The child presented essentially a central anti-cholinergic syndrome. She was admitted in the intensive care unit, the progression was favorable with symptomatic treatment.

    Clinical observations indicate that large oral doses of castor oil are effective in reducing the time of coma resulting from acute intoxication with lipophilic drugs. It has been further suggested that the rate of removal of these drugs from the body is increased by castor oil. In order to investigate the effect of castor oil on the disposition of lipophilic drugs, five dogs were given toxic doses of methyprylon by intravenous infusion. Each dog was treated with a large oral dose of castor oil in a cross-over fashion. No significant difference was observed in the sleep times of the dogs treated with castor oil, or in the methyprylon pharmacokinetics compared to controls. It was concluded that castor oil does not affect the disposition of methyprylon.

    Traditional bath salts contain a combination of inorganic salts like Epsom salts, table salt, baking soda, sodium metaphosphate, and borax that have cleansing properties. Since 2010, there have been rising concerns about a new type of substance abuse in the name of "bath salts." They are beta-ketone amphetamine analogs and are derivates of cathinone, a naturally occurring amphetamine analog found in the "khat" plant (Catha edulis). Effects reported with intake included increased energy, empathy, openness, and increased libido. Serious adverse effects reported with intoxication included cardiac, psychiatric, and neurological signs and symptoms. Not much is known about the toxicology and metabolism of these compounds. They inhibit monoamine reuptake (dopamine, nor epinephrine, etc.) and act as central nervous system stimulants with high additive and abuse potential because of their clinical and biochemical similarities to effects from use of cocaine, amphetamine, and 3,4-methylenedioxy-N-methylamphetamine. Deaths associated with use of these compounds have also been reported. We report a case of acute kidney injury associated with the use of "bath salt" pills that improved with hemodialysis. © 2012 The Authors.

In this secondary analysis of existing data, we examined event-specific associations between self-report measures of tobacco smoking and breath alcohol concentration (BrAC) readings obtained from 424 patrons exiting on-premise drinking establishments. In a multivariable logistic regression analysis, acute alcohol intoxication was positively associated with same-night incidents of smoking tobacco, adjusting for the effects of established smoking practices and other potential confounders. This investigation is the first known study using data collected in an on-premise drinking setting to link alcohol intoxication to specific incidents of tobacco smoking.

    The effect of increasing the time interval between acute uranium exposure and chelation therapy was studied in male Swiss mice. Gallic acid, 4,5-dihydroxy-1,3- benzenedisulfonic acid (Tiron), diethylenetriaminepentaacetic acid (DTPA), and 5-aminosalicylic acid (5-AS) were administered ip at 0, 0.25, 1, 4, and 24 hr after sc injection of 10 mg/kg of uranyl acetate dihydrate. Chelating agents were given at doses equal to one-fourth of their respective LD50 values. Daily elimination of uranium into urine and feces was determined for 4 days after which time the mice were killed, and the concentration of uranium was measured in kidney, spleen, and bone. The excretion of uranium was especially rapid in the first 24 hr. Treatment with Tiron or gallic acid at 0, 0.25, or 1 hr after uranium exposure significantly increased the total excretion of the metal. In kidney and bone, only administration of Tiron at 0, 0.25, or 1 hr after uranium injection, or gallic acid at 1 hr after uranium exposure significantly reduced tissue uranium concentrations. Treatment at later times (4 to 24 hr) did not increase the total excretion of the metal and did not decrease the tissue uranium concentrations 4 days after uranyl acetate administration. The results show that the length of time before initiating chelation therapy for acute uranium intoxication greatly influences the effectiveness of this therapy

    Full Text Available Delayed encephalopathy (DE is a neuropsychiatric syndrome that can arise generally within 20 days of acute carbon monoxide (CO intoxication after apparent recovery and involves variable degrees of cognitive deficits, personality changes, movement disorders and focal neurologic deficits. We report a 35-year-old female patient with delayed encephalopathy due to CO intoxication, presenting with cognitive impairment and mild parkinsonism despite receiving hyberbaric oxigen therapy (HBO. Magnetic resonance imaging showed abnormal signal intensity and decreased diffusivity at both caudate nuclei and globus pallidus. She continued to receive additional HBO therapy and complete recovery was reached within six months. The positive effect of early HBO therapy of selected patients in reversing the acute effects of CO intoxication is appearant. We here also review the beneficial effect of HBO in preventing or limitating the late neurocognitive deficits associated with severe CO intoxication

    To assess the relationship between ambulance attendances, emergency department (ED) presentations and hospital admissions for acute alcohol intoxication and the timing of public holidays, sporting and social events. Time-series analysis was used to explore trends in intoxication in the context of major events. Population of Melbourne, Victoria, Australia between 2000 and 2009. All patients attended by ambulance, presenting to hospital EDs, or admitted to hospital who were classified as acutely alcohol intoxicated. Analysis of daily numbers of presentations for acute alcohol intoxication associated with major events were undertaken, including lead and lag effects. Analyses controlled for day of week and month of year to address temporal and seasonal variations. Alcohol intoxication presentations were significantly elevated the day before all public holidays, with intoxication cases on the day of public holidays only higher on New Year's Day (ambulance 6.57, 95% confidence intervals (CI): 3.4-9.74; ED 3.34, 95% CI: 1.28-5.4) and ANZAC Day (ambulance 3.71, 95% CI: 0.68-6.75). The Australian Football League (AFL) Grand Final (ED 2.37, 95% CI: 0.55-4.19), Commonwealth Games (ED 2.45, 95% CI: 0.6-4.3) and Melbourne Cup Day (ambulance 6.14, 95% CI: 2.42-9.85) represented the sporting events with significant elevations in acute intoxication requiring medical attention. The last working day before Christmas was the only social event where a significant increase in acute intoxication occurred (ambulance 8.98, 95% CI: 6.8-11.15). Acute alcohol intoxication cases requiring ambulance, emergency department and hospital in-patient treatment increase substantially on the day preceding public holidays and other major social events. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    The increase in agricultural activity that Chile experienced in the past 20 years resulted in a boost in the use of pesticides. Despite pesticides' productivity benefits, they caused health problems such as the increased frequency of episodes of acute poisoning, which constitutes a relevant problem in terms of occupational health. The Chilean authorities require several preventive measures at workplaces, which are not always implemented, increasing the risk of intoxications in farmers. So far in Chile, there are no studies concerning the public health care expenses associated with acute work-related pesticide intoxications. From the societal perspective, there are costs involved if the worker needs to take sick leave and families incur costs to take care of their sick members. This study aimed to determine the costs associated with health care services used by people who suffered from work-related acute pesticide poisoning, as well as the economic costs for the families of the workers involved, and finally the costs of these episodes for the employer/industrial sector. This study considered a 3-year period (January 2009 to December 2011). Three sources of data were reviewed: reported cases at the Regional Health Authority, for the profile of the intoxications; registers of patients attended in public hospitals, for data on costs of health care services; and public information of living conditions nationwide. The overall costs of a single case depend on the severity of intoxication, days of sick leave, and type of health care needed. Most cases (77%) would be ambulatory and would be assisted at an emergency room, with an average cost of US $330 per case. Those cases that might need hospitalization (23%) and, therefore, more days off work have an average cost of US $1158 per case. Taking into account the number of patients reported each year in the country, the cost per annum would be about US $185,000, but considering the underreporting of intoxications and

    Usage of enterosorbents in treatment of almost all types of acute and chronic disorders accompanied with endogenous intoxication syndrome takes on special significance. The critical point of endogenous intoxication pathogenesis is dysfunction of microbiocenosis and intestinal barrier. The necessity of enterosorbents usage is very high due to their efficacy, safety and wide availability. Smectite dioctaedric (diosmectite), which has been successfully used in clinical practice for a long period...

    Full Text Available Background: Aluminum phosphide as a fumigant is extensively used for wheat preservation from rodents and bugs especially in silos worldwide. There is increasing number of acute intoxication with this potentially lethal compound because of its easy availability. We have tried to locate predictors of poor prognosis in patients with aluminum phosphide intoxication in order to find patients who need more strict medical cares. Methods: All cases of aluminum phosphide intoxication that had been referred to our hospital during April 2008 to March 2010 were studied by their medical dossiers. Pertinent data including vital signs, demographic features, clinical and lab findings, and incidence of any complication were collected and analyzed by the relevant statistical methods. Results: Sixty seven cases of aluminum phosphide intoxication were included in the study. 44.8% of them were male. 97% of cases were suicidal. Mean amount of ingestion was 1.23+/- 0.71 tablets. Mortality rate was 41.8%. ECG abnormality and need for mechanical ventilation had negative relation with outcome. Conclusion: Correlation between some findings and complications with outcome in aluminum phosphide intoxication can be used as guidance for risk assessment and treatment planning in the patients.

    Coffee, tea, chocolate and caffeinated drinks are the main sources of caffeine, which is consumed in almost all ages and socioeconomic levels. Caffeine acts as a non-selective adenosine receptor antagonist in the central nervous system. Its main effects are as psychostimulant, acting in addition on the respiratory, muscular and cardiovascular systems. Basically, caffeine is metabolized by the hepatic cytochrome P-450 1A2 enzymes (CYP1A2). Several drugs can interact with its metabolism. The observed interindividual differences of its effects can be explained by variations in its metabolism. The main therapeutic use of caffeine is bronchodilator in respiratory diseases. Other possible uses are under investigation. Acute or chronic consumption of caffeine can induce several adverse effects, including intoxication that can be lethal. Finally, caffeine can be considered a drug of abuse. It has positive reinforcing actions, produces tolerance, and a withdrawal syndrome after stopping its consumption. Caffeine can cause different mental disorders such as dependence, which is not included in the DSM-IV-R, withdrawal syndrome and intoxication. Depending on its use, caffeine can be considered a nutrient, a drug or a drug of abuse.

    The relationship between exposure duration, COHb, blood glucose, pyruvate and lactate and the severity of intoxication was investigated in a group of 39 cases of acute CO poisoning treated in the Clinical Toxicology Center in Lodz, Poland. On the basis of clinical criteria the patients were classified into cases of mild, moderate, severe and very severe CO poisoning. COHb and carbohydrate metabolites were estimated in venous blood taken immediately after admission of the patient to hospital prior to treatment. The severity of intoxication did not correlate with blood COHb; variation in exposure duration seems to be responsible for this phenomenon. Severe and very severe poisonings were associated with longer exposures and were accompanied by a markedly higher blood lactate level, compared to mild and moderate cases. Blood pyruvate depended less than lactate on the severity of intoxication. Blood glucose depended neither on exposure duration nor on the severity of intoxication. Among the carbohydrate metabolic parameters studied, blood lactate determination can be helpful in the evaluation of the severity of CO poisoning in man.

  10. Nonacetaminophen Drug-Induced Acute Liver Failure.

    2018-05-01

    Acute liver failure of all causes is diagnosed in between 2000 and 2500 patients annually in the United States. Drug-induced acute liver failure is the leading cause of acute liver failure, accounting for more than 50% of cases. Nonacetaminophen drug injury represents 11% of all cases in the latest registry from the US Acute Liver Failure Study Group. Although rare, acute liver failure is clinically dramatic when it occurs, and requires a multidisciplinary approach to management. In contrast with acetaminophen-induced acute liver failure, non-acetaminophen-induced acute liver failure has a more ominous prognosis with a lower liver transplant-free survival.

    1994-01-01

    A series of 100 murderers was examined to discern patterns of substance abuse and intoxication in relation to homicidal events. More than half of the study subjects were found to be actively abusing drugs at the time of their crime, and almost half were intoxicated. Alcohol was the drug most often abused. Demographic and other discriminating factors were utilized to examine the hypothesis that murderers do not constitute a homogeneous population and that subgroups differ in their abuse patterns. Cluster analytic techniques were applied to the study population. Utilizing a set of 13 proximate causal factors, a typology of seven distinct homicide profiles was created. Two of the seven profiles exhibited extremely high abuse and intoxication rates, three others intermediate rates, and two profiles very low rates. Moreover, different substances were prime offenders in different profiles. These findings demonstrate that substance abuse is an important etiological contributor in some types of murderer but not in all types.

    A study of amoxicillin pharmacokinetics was conducted in healthy goats and goats with chronic lead intoxication. The intoxicated goats had increased serum concentrations of liver enzymes (alanine aminotransferase and γ-glutamyl transferase), blood urea nitrogen, and reactivated δ-aminolevulinic acid dehydratase compared to the controls. Following intravenous amoxicillin (10 mg/kg bw) in control and lead-intoxicated goats, elimination half-lives were 4.14 and 1.26 h, respectively. The volumes of distribution based on the terminal phase were 1.19 and 0.38 L/kg, respectively, and those at steady-state were 0.54 and 0.18 L/kg, respectively. After intramuscular (IM) amoxicillin (10 mg/kg bw) in lead-intoxicated goats and control animals, the absorption, distribution, and elimination of the drug were more rapid in lead-intoxicated goats than the controls. Peak serum concentrations of 21.89 and 12.19 μg/mL were achieved at 1 h and 2 h, respectively, in lead-intoxicated and control goats. Amoxicillin bioavailability in the lead-intoxicated goats decreased 20% compared to the controls. After amoxicillin, more of the drug was excreted in the urine from lead-intoxicated goats than the controls. Our results suggested that lead intoxication in goats increases the rate of amoxicillin absorption after IM administration and distribution and elimination. Thus, lead intoxication may impair the therapeutic effectiveness of amoxicillin.

  14. Content of carbon monoxide in the tissues of rats intoxicated with carbon monoxide in various conditions of acute exposure

    Energy Technology Data Exchange (ETDEWEB)

    Sokal, J.A.; Majka, J.; Palus, J.

    1984-12-01

    Tissue carbon monoxide (CO) content was investigated in rats severely intoxicated with CO under various exposure conditions: 1% CO for 4 min, 0.4% CO for 40 min and 0.12% CO for 12 h. Extravascular CO was determined in the heart and skeletal muscles immediately after termination of exposure, and carboxymyoglobin (MbCO) percent saturation was calculated. Total brain CO was estimated immediately after termination of exposure and after the time periods of restitution. After the same exposure conditions, MbCO percent saturation was higher in the heart than in skeletal muscle. In both types of muscle, saturation on myoglobin (Mb) with CO depended on blood carboxyhemoglobin (HbCO) level and not on the duration of exposure. The time course of CO elimination was the same for blood and brain, irrespective of CO exposure conditions. The results obtained showed that acute CO intoxication induced by long duration exposures did not involve CO accumulation in the tissues.

    During the course of investigation of two infants with seizure disorders it was discovered that both had been given large amounts of a preparation of borax and honey which resulted in chronic borate intoxication. In one child a profound anemia developed as well. The symptoms of chronic borate intoxication are different from those of the acute poisoning with which we are more familiar. The borax and honey preparations are highly dangerous and should no longer be manufactured or distributed for sale. ImagesFIG. 1FIG. 2 PMID:4691106

    The ferric chloride intoxication is frequently caused by accident. Its toxicity is generally underrated, which can lead to fatal evolution or irreversible consequences. In this case, the caustic condition of the substance is related to the toxic properties of iron. A 36-year-old male patient arrives by ambulance indicating sensory deterioration. He presents erosive injuries in the buccal cavity and in the oropharynx, brownish teeth and metabolic acidosis. Toxicology tests and ferritin blood dosage are requested, which show a result from 1400 mg/dl. The symptoms are interpreted as acute iron intoxication. Due to the unfavorable evolution of his condition, an abdominal and pelvic CT scan are performed, which show extensive pneumoperitoneum and free fluid in the abdominal cavity. An exploratory laparotomy, a total gastrectomy with esophagostomy and feeding jejunostomy, washing and drainage due to perforated gastric necrosis caused by caustic ingestion are performed. In our country, there is a high rate of intoxication caused by iron compounds, although it is not statistically measured. Nevertheless, the ferric chloride intoxication is extremely infrequent. The ingestion of this product leads to complications, which are associated with the iron concentration and its condition as a caustic agent. The surgical indications in the presence of intoxication caused by iron compounds are: stomach evacuation of iron, gastric necrosis, perforation or peritonitis and stenosis. Early or prophylactic gastrectomy is contraindicated. However, if complications that require immediate surgical intervention arise, there should be no hesitation and the corresponding procedure should be performed.

    Increased of proinflammatory cytokines levels, including interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha) on severe acute pancreatitis causes vasodilatation, increased permeability of the wall, accumulation of fluid in lung tissue and pleural sinuses. Transudate from acute parapancreatyc clusters of hot liquid and abdomen falls into the chest cavity through microscopic defects in the diaphragm due to the formation of pathological pleural-peritoneal connections or the relevant pressure gradient between the abdominal and pleural cavities. Remediation and removal of acute parapancreatyc clusters combined with the use of a multicomponent drug infusion therapy Cytoflavin provide a reduction in the frequency of pulmonary complications of acute pancreatitis from 48.3 to 31.0%. Use of the drug Cytoflavin reduces the severity of endogenous intoxication and mortality from acute lung injury from 12.9 to 6.1%.

    Xylazine is not a controlled substance; it is marketed as a veterinary drug and used as a sedative, analgesic and muscle relaxant. In humans, it could cause central nervous system depression, respiratory depression, bradycardia, hypotension, and even death. There have been publications of 43 cases of xylazine intoxication in humans, in which 21 (49%) were non-fatal scenarios and 22 (51%) resulted in fatalities. Most of the non-fatal cases required medical intervention. Over recent years xylazine has emerged as an adulterant in recreational drugs, such as heroin or speedball (a cocaine and heroin mixture). From the 43 reported cases, 17 (40%) were associated with the use of xylazine as an adulterant of drugs of abuse. Its chronic use is reported to be associated with physical deterioration and skin ulceration. Literature shows some similar pharmacologic effects between xylazine and heroin in humans. These similar pharmacologic effects may create synergistic toxic effects in humans. Therefore, fatalities among drug users may increase due to the use of xylazine as an adulterant. Xylazine alone has proven harmful to humans and even more when it is combined with drugs of abuse. A comprehensive review of the literature of non-fatal and fatal xylazine intoxication cases including those in which the substance was used as adulterant is presented, in order to increase the awareness in the forensic community, law enforcement, and public health agencies.

    It is now well documented that postnatal exposure to certain chemicals has been reported to increase the risk of autism spectrum disorder. Propionic acid (PA), as a metabolic product of gut microbiotaandas a commonly used food additive, has been reported to mediate the effects of autism. Results from animal studies may help to identify environmental neurotoxic agents and drugs that can ameliorate neurotoxicity and may thereby aid in the treatment of autism. The present study investigated the ameliorative effects of natural bee pollen against acute and sub-acute brain intoxication induced by (PA) in rats. Twenty-four young male Western Albino ratswere enrolled in the present study. They were classified into four equal groups, eachwith6 rats. The control group received only phosphate buffered saline; the oral buffered PA-treated groups (II and III) received a neurotoxic dose of 750 mg/kg body weight divided in 3 dose of 250 mg/kg body weight/day serving asthe acute group and 750 mg/kg body weight divided in 10 equal dose of 75 mg/kg body weight/day as the sub-acute group. The fourth group received 50 mg bee pollen for 30 days after PA-acute intoxication. The obtained data showed that the PA-treated groups demonstrated multiple signs of brain toxicity, as indicated by a depletion of serotonin (5HT), dopamine and nor-adrenaline, together withan increase in IFN-γ and caspase 3. Bee pollen was effective in ameliorating the neurotoxic effect of PA. All measured parameters demonstrated minimal alteration in comparison with thecontrol animal than did those of acute and sub-acute PA-treated animals. In conclusion, bee pollen demonstrates anti-inflammatory and anti-apoptotic effects while ameliorating the impaired neurochemistry of PA-intoxicated rats.

    Purpose: To quantify the correlation between fat content of an acute alcohol intoxication and the difference of computer tomography attenuation value in dual-energy CT in comparison to biochemical triglyceride analysis and to evaluate qualitatively the value of DECT in the diagnosis of fatty liver caused by ethanol-dosage in rats. Materials and Methods: DECT at 140 kV and 80 kV was performed on 20 rats before and two days after the administration of 3 ml of 50 % ethanol. The CT attenuation value in the livers at 140 kV, 80 kV and the differences between them in Hounsfield units (ΔH) were collected. Parts of the liver (100 mg) were measured in biochemical triglyceride analysis as the reference standard. A blood sample was also taken to measure specific liver enzymes. Results: Linear correlation between biochemical triglyceride analysis and CT density of ΔH was found (r = 0.949). 140 kV attenuation data were between 44 HU and 61.3 HU, 80 kV attenuation data were between 58.4 HU and 64.7 HU, and ΔH data were between 3.4 HU and 14.4 HU (p ≤ 0.037). The biochemical triglyceride analysis data were between 7.1 mg/g and 41.1 mg/g. The hepatic enzymes serum aspartate (ASAT) aminotransferase and alanine aminotransferase (ALAT) were elevated in all rats. ASAT correlated directly with ΔHU (r = -0.86). Conclusion: DECT provides a non-invasive method to determine and evaluate hepatic fat content after acute alcohol intoxication. It provides the possibility to detect and quantify the hepatic fat content of liver graft. (orig.)

    Comparative study of the ability of the sodium salt of diethylbarbituric acid and acetazolamide to protect the kidneys is conducted under conditions of acute uranium intoxication in rats. The parameters studied are alkaline and acid phosphatase activities in the serum and urine and phosphatase activity in the kidneys (histochemically as described by Gomori) followed up until the 30th day after the total uranyl acetate dose was reached (2 or 7 mg per kg bodyweight). Either compound exerted only minor effect on serum alkaline phosphatase activity. Sodium diethylbarbiturate induced distinct fluctuations in urinary alkaline phosphatase activity throughout the entire study period, but the differences never reached statistical significance. Acetazolamide caused essential decrease in urinary alkaline phosphatase activity. In either case renal tissue protection from the action of the uranyl ion may be suggested. This assumption is supported by the histochemical analysis. The compounds appeared to have no effect on serum acid phosphatase activity which showed high variability both in control and in treated rats. (Ch.K.)

    Cyanobacterial blooms and hepatotoxic microcystins (MCs) usually occur in summer, constituting a sanitary and environmental problem in Salto Grande Dam, Argentina. Water sports and recreational activities take place in summer in this lake. We reported an acute case of cyanobacterial poisoning in Salto Grande dam, Argentina, which occurred in January 2007. Accidentally, a young man was immersed in an intense bloom of Microcystis spp. A level of 48.6 μg·L(-1) of microcystin-LR was detected in water samples. Four hours after exposure, the patient showed nausea, abdominal pain and fever. Three days later, dyspnea and respiratory distress were reported. The patient was hospitalized in intensive care and diagnosed with an atypical pneumonia. Finally, a week after the exposure, the patient developed a hepatotoxicosis with a significant increase of hepatic damage biomarkers (ALT, AST and γGT). Complete recovery took place within 20 days. This is the first study to show an acute intoxication with microcystin-producing cyanobacteria blooms in recreational water.

    Pulmonary toxicity of lead was studied in rats after an intraperitoneal administration of lead acetate at a dose of 25 mg/kg. Three consecutive days of treatment increased lead content in the whole blood to 2.1 µg/dl and in lung homogenate it attained 9.62 µg/g w.w. versus control values of 0.17 µg/dl and 0.78 µg/g w.w., respectively. At the ultrastructural level, the effects of lead toxicity were observed in lung capillaries, interstitium, epithelial cells and alveolar lining layer. Accumulation of aggregated platelets, leucocytic elements and monocytes was found within capillaries. Interstitium comprised a substantial number of collagen, elastin filaments and lipofibroblasts. Lamellar bodies of type II pneumocytes contained phospolipid lamellae, which stratified into an irregular arrangement. Pulmonary alveoli were filled with macrophages. The extracellular lining layer of lung alveoli was partially destroyed. This study provided evidence that acute lead intoxication affects the whole lung parenchyma and by impairing production of the surfactant might disturb the regular respiratory function.

    Acute cadmium intoxication affects glutathione S-transferase (GST) in rat liver. It has been found that 24 h after i.p. cadmium administration to rats, at a dose of 2.5 mg CdCl 2 kg -1 body weight, the activity of this enzyme in liver cytosol increased by 40%. A less stimulatory effect persisted till 48 h and thereafter the enzyme activity normalized. Since, GST isoenzymes belong to different classes in mammalian tissues, we used quantitative immunoassays to verify which family of GST isoenzymes is influenced by this intoxication. Only alpha-class glutathione S-transferase (α-GST) proteins were detected in rat liver cytosol and their level increased by about 25%, 24 h after cadmium treatment. No pi-GST isoforms were found in liver cytosol from either normal or cadmium-treated rats. Co-administration of actinomycin D with cadmium normalized both the protein level and the activity of α-GST, suggesting that some effect occurs on enzyme transcription of these isoenzymes by this metal. On the other hand, it seems unlikely that the stimulatory effect is due to the high level of peroxides caused by lipid peroxidation, since Vitamin E administration strongly reduced the TBARS level, but did not cause any GST activity decrease

    Full Text Available Valproic acid is a commonly used antiepileptic drug which causes intoxication easily due to its narrow therapeutic window. Here, we present a child with valproic acid poisoning who responded to hemodialysis. A 14-year-old male patient with epilepsy and mental motor retardation was admitted to the pediatric intensive care unit due to valproic acid intoxication. Plasma valproic acid level was 710 µg/mL. The patient’s vital signs were stable and a decrease was observed in the valproic acid and ammonia levels with supportive treatment at the beginning. On the third day of the admission, hemodynamic and mental status of the patient deteriorated, plasma ammonia and lactate levels elevated, thus, we decided to perform hemodialysis. After hemodialysis, the patient’s hemodynamic status and mental function improved in conjunction with the reduction in valproic acid, ammonia and lactate levels. Thus he was transferred to the pediatric ward. Hemodialysis may be considered an effective treatment choice for severe valproic acid intoxication. Here, it was shown that hemodialysis may also be effective in patients with deteriorated general status under supportive treatment in the late phase of valproic acid intoxication.

    We present the case histories, autopsy findings and toxicology findings of two fatal intoxications involving the designer drug, butyryl fentanyl. The quantitative analysis of butyryl fentanyl in postmortem fluids and tissues was performed by an ultrahigh-performance liquid chromatography tandem mass spectrometry method. In the first case, butyryl fentanyl was the only drug detected with concentrations of 99 ng/mL in peripheral blood, 220 ng/mL in heart blood, 32 ng/mL in vitreous humor, 590 ng/mL in gastric contents, 93 ng/g in brain, 41 ng/g in liver, 260 ng/mL in bile and 64 ng/mL in urine. The cause of death was ruled fatal intoxication by butyryl fentanyl. In the second case, butyryl fentanyl was detected along with acetyl fentanyl, alprazolam and ethanol. The butyryl fentanyl concentrations were 3.7 ng/mL in peripheral blood, 9.2 ng/mL in heart blood, 9.8 ng/mL in vitreous humor, 4,000 ng/mL in gastric contents, 63 ng/g in brain, 39 ng/g in liver, 49 ng/mL in bile and 2 ng/mL in urine. The acetyl fentanyl concentrations were 21 ng/mL in peripheral blood, 95 ng/mL in heart blood, 68 ng/mL in vitreous humor, 28,000 ng/mL in gastric contents, 200 ng/g in brain, 160 ng/g in liver, 330 ng/mL in bile and 8 ng/mL in urine. In addition, the alprazolam concentration was 40 ng/mL and the ethanol concentration was 0.11 g/dL, both measured in peripheral blood. The cause of death in the second case was ruled a mixed drug intoxication. In both cases, the manner of death was accident. PMID:27339481

    Alcohol and cannabis use have been implicated in aggression. Alcohol consumption is known to facilitate aggression, whereas a causal link between cannabis and aggression has not been clearly demonstrated. This study investigated the acute effects of alcohol and cannabis on subjective aggression in alcohol and cannabis users, respectively, following aggression exposure. Drug-free controls served as a reference. It was hypothesized that aggression exposure would increase subjective aggression in alcohol users during alcohol intoxication, whereas it was expected to decrease subjective aggression in cannabis users during cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21), and controls (n = 20) were included in a mixed factorial study. Alcohol and cannabis users received single doses of alcohol and placebo or cannabis and placebo, respectively. Subjective aggression was assessed before and after aggression exposure consisting of administrations of the point-subtraction aggression paradigm (PSAP) and the single category implicit association test (SC-IAT). Testosterone and cortisol levels in response to alcohol/cannabis treatment and aggression exposure were recorded as secondary outcome measures. Subjective aggression significantly increased following aggression exposure in all groups while being sober. Alcohol intoxication increased subjective aggression whereas cannabis decreased the subjective aggression following aggression exposure. Aggressive responses during the PSAP increased following alcohol and decreased following cannabis relative to placebo. Changes in aggressive feeling or response were not correlated to the neuroendocrine response to treatments. It is concluded that alcohol facilitates feelings of aggression whereas cannabis diminishes aggressive feelings in heavy alcohol and regular cannabis users, respectively.

    Full Text Available Abstract Background Plenty of information related to alcoholism can be found in the literature, however, the studies have mostly dealt with the predominance of male alcoholism and data related to addiction in women are desperately scarce and difficult to find. Basic demographic data focusing on the impact of acute alcohol intoxication on the circumstances of death and social behaviour in the alcohol addicted female population are needed especially in the prevention of alcohol related mortality. Methods A retrospective forensic autopsy study of all accidental deaths due to alcohol intoxication over a 12-year period was performed in order to evaluate the locations, circumstances, mechanisms and causes of death. Results A sample of 171 cases of intoxicated women who died due to blood alcohol concentration (BAC equal to or higher than 2 g/kg was selected. Among them 36.26% (62/171 of women died due to acute alcohol intoxication (AAI. We noted an increase in the number of deaths in women due to AAI from 2 in 1994 up to 5 in 2005 (an elevation of 150% between the years 1994-2005. The age structure of deaths in women due to BAC and AAI followed the Gaussian distribution with a dominant group of women aged 41-50 years (45.16% and 35.09% respectively. The most frequent place of death (98% among women intoxicated by alcohol was their own home. The study suggests a close connection between AAI and violence against women. Conclusions The increasing number of cases of death of women suffering from AAI has drawn attention to the serious problem of alcoholism in women in the Slovak Republic during the process of integration into "western" lifestyle and culture.

    Drugs of abuse stimulate striatal dopamine release and activate reward pathways. This study examined the impact of alcohol and cannabis marketing on the reward circuit in alcohol and cannabis users while sober and intoxicated. It was predicted that alcohol and cannabis marketing would increase striatal activation when sober and that reward sensitivity would be less during alcohol and cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21) participated in a mixed factorial study involving administration of alcohol and placebo in the alcohol group and cannabis and placebo in the cannabis group. Non-drug users (n = 20) served as between group reference. Brain activation after exposure to alcohol and cannabis marketing movies was measured using functional magnetic resonance imaging and compared between groups while sober and compared with placebo while intoxicated. Implicit alcohol and cannabis cognitions were assessed by means of a single-category implicit association test. Alcohol and cannabis marketing significantly increased striatal BOLD activation across all groups while sober. Striatal activation however decreased during intoxication with alcohol and cannabis. Implicit associations with cannabis marketing cues were significantly more positive in alcohol and cannabis users as compared with non-drug using controls. Public advertising of alcohol or cannabis use elicits striatal activation in the brain's reward circuit. Reduction of marketing would reduce brain exposure to reward cues that motivate substance use. Conversely, elevated dopamine levels protect against the reinforcing potential of marketing. © 2016 Society for the Study of Addiction.

    Providing effective pain management to acutely intoxicated trauma patients represents a challenge of balancing appropriate pain management with the risk of potential respiratory depression from opioid administration. The objective of this study was to quantify the incidence of respiratory depression in trauma patients acutely intoxicated with ethanol who received opioids as compared with those who did not and identify potential risk factors for respiratory depression in this population. Retrospective medical record review was conducted for subjects identified via the trauma registry who were admitted as a trauma activation and had a detectable serum ethanol level upon admission. Risk factors and characteristics compared included demographics, Injury Severity Score, Glasgow Coma Score, serum ethanol level upon arrival, urine drug screen results, incidence of respiratory depression, and opioid and other sedative medication use. A total of 233 patients were included (78.5% male). Patients who received opioids were more likely to have a higher Injury Severity Score and initial pain score on admission as compared with those who did not receive opioids. Blood ethanol content was higher in patients who did not receive opioids (0.205 vs 0.237 mg/dL, P = .015). Patients who did not receive opioids were more likely to be intubated within 4 hours of admission (1.7% vs 12.1%, P = .02). Opioid administration was not associated with increased risk of respiratory depression (19.7% vs 22.4%, P = .606). Increased cumulative fentanyl dose was associated with increased risk of respiratory depression. Increased cumulative fentanyl dose, but not opioid administration alone, was found to be a risk factor for respiratory depression. Copyright © 2015 Elsevier Inc. All rights reserved.

    We present a case of acute carbon monoxide (CO) intoxication in a previously healthy 13-year-old girl, who was found in the bathroom, unconscious and with the gas-burning hot water thank operating. The neuroradiological study showed bilateral, symmetrical cortical and subcortical parietooccipital and temporal lesions as well as damage to the basal lymph nodes. These lesions were related to the anoxic situation induced by this type of intoxication. Clinicoradiological follow-up included CT and MR sequences over a period of 10 months. In this cases, we stress the greater sensitivity of MR in the early detection of the characteristic lesions in this situation and we analyze the evolution of the process. (Author)

    To identify prevalence of alcohol and drug use and intoxication at work. A total of 9,828 Australian workers ≥14 years old. Australia 2007. Work-place alcohol use and drug use, intoxication at work, industry and occupation of employment. Secondary analysis of a large nationally representative survey involving descriptive and weighted multivariate logistic regressions. Differential patterns were identified by drug type, worker characteristics and occupational setting, controlling for demographic variables. Nearly 9% of workers surveyed (8.7%) usually drank alcohol at work and 0.9% usually used drugs at work. Attending work under the influence of alcohol was more prevalent (5.6%) than attending work under the influence of drugs (2.0%), and significantly more likely among young, male, never married workers with no dependent children. Hospitality industry workers were 3.5 times more likely than other workers to drink alcohol and two to three times more likely to use drugs at work or attend work under the influence of alcohol or drugs. Other high-risk industries and occupations included construction, financial services, tradespersons and unskilled workers. More than one in 20 Australian workers admit to having worked under the influence of alcohol and almost one in 50 report attending work under the influence of psychoactive drugs. The rates are higher for some industries, such as the hospitality industry, than others. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Full Text Available The chemical control of rodents with anticoagulant products, especially derivatives of the coumarin chemical group, is legally authorised in Brazil. These products provide effective control and are safe for humans. However, the use of illegal 'rodenticides' has increased in many Brazilian cities recently, accompanied by increased numbers of suicides, homicides, and intoxications. The National Toxicology Information System (Sinitox registers the number of rodenticide intoxications, including suicides, but does not differentiate between the legal and illegal rodenticides. Intoxications by rodenticides outnumber those by illicit drugs and pesticides. A survey of data from 2005-2011 revealed an average of about 3,800 intoxications per year, about 60% of which were suicides. Many of these intoxications probably involved illegal rodenticides, some with unknown chemical compositions, which confound the data on rodenticide intoxication. This evaluation of Sinitox data highlighted the need to ensure the proper use of the term 'rodenticide' when registering intoxication cases. Intoxication by-products that are not rodenticides, but are erroneously used for this purpose, should be classified separately to improve the quality of information.

    The emergence of a large number of new psychoactive substances (NPSs) in recent years poses a serious problem to clinical and forensic toxicologists. Here we report a patient who administrated ca. 500mg of 3-MMC (3-methyl-N-methylcathinone) and 400mg of 5-APB (5-(2-aminopropyl)benzofuran) in combination with 80g of ethyl alcohol. The clinical manifestations included agitation, seizures, hypertension, tachycardia, hyperthermia and bradycardia. The patient did not recover and died around 4h after the use of drugs. The cause of death was acute cardiovascular collapse that occurred following mixed intoxication with NPSs and alcohol. Toxicological analysis of post-mortem blood revealed 3-MMC and 5-APB in concentrations of 1.6μg/mL and 5.6μg/mL, respectively. Moreover, the serum alcohol concentration was 1.4g/L in ante-mortem sample collected 1h after admission to the hospital. This is the first report on blood concentration of 3-MMC and 5-APB in fatal intoxication. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

MÉTODOS: a partir de dados secundários do Sistema Nacional de Informações Tóxico-Farmacológicas (SINITOX foram analisadas as freqüências por classe terapêutica, seguimento e circunstâncias, dos casos de intoxicação em menores de cinco anos, nos anos de 1997 e 1998 em São Paulo e Rio Grande do Sul. RESULTADOS: no Brasil, foram registrados no período, 151.000 casos de intoxicações humanas. Quase um terço pôde ser associado a medicamentos, sendo que cerca de 40.000 casos ocorreram entre crianças menores de cinco anos. O maior número de casos correspondeu aos descongestionantes nasais, analgésicos, broncodilatadores, anticonvulsivantes, anti-histamínicos e contraceptivos orais. Os descongestionantes nasais, anticonvulsivantes, anti-histamínicos e expectorantes foram responsabilizados pelos óbitos. Conforme o SINITOX as principais circunstâncias dos eventos foram o acidente individual, o erro de administração e o uso terapêutico. CONCLUSÕES: as intoxicações medicamentosas representam um grave problema de saúde pública, que necessita intervenções no campo da prevenção e da promoção. Isto demonstra a necessidade de ações educativas, junto à população para reduzir o número de acidentes e injurias.

    This study presents the case of a 4-year-old healthy child admitted to the paediatric ward for suspected accidental intoxication due to ingestion of narcoleptic drugs (methylphenidate, sertraline and quetiapine), taken on a regular basis by his 8-year-old brother affected by Asperger syndrome.Intoxication can be objectively assessed by measurements of drugs and metabolites in biological matrices with short-term (blood and urine) or long-term (hair) detection windows. At the hospital, the child's blood and urine were analysed by immunoassay (confirmed by liquid chromatography-mass spectrometry), and sertraline and quetiapine and their metabolites were identified. The suspicion that the mother administered drugs chronically prompted the analysis of six, consecutive 2-cm segments of the child's hair, using ultra-high performance liquid chromatography-tandem mass spectrometry, thereby accounting for ingestion over the previous 12 months. Quetiapine was found in the first four segments with a mean concentration of 1.00 ng/mg ± 0.94 ng/mg hair while sertraline and its metabolite, desmethyl-sertraline, were found in all segments with a mean concentration of 2.65 ± 0.94 ng/mg and 1.50 ± 0.94 ng/mg hair, respectively. Hair analyses were negative for methylphenidate and its metabolite (ritalinic acid). Biological matrices testing for psychoactive drugs disclosed both acute and chronic intoxication with quetiapine and sertraline administered by the mother.

    Full Text Available Usage of enterosorbents in treatment of almost all types of acute and chronic disorders accompanied with endogenous intoxication syndrome takes on special significance. The critical point of endogenous intoxication pathogenesis is dysfunction of microbiocenosis and intestinal barrier. The necessity of enterosorbents usage is very high due to their efficacy, safety and wide availability. Smectite dioctaedric (diosmectite, which has been successfully used in clinical practice for a long period of time, is of an increased interest among the natural enterosorbents. The main quality of diosmectite is its restoration effect on the microbiocenisis and intestinal barrier function, and with a high degree of evidence-based efficacy and safety.

    Full Text Available Benzene is a widely spread chemical health risk factor. Our research goal was to examine the nervous system state and the blood system state under benzene intoxication during an experiment. An acute experiment was performed on 45 white mice with 5-fold poisoning with benzene; a chronic one was performed on 72 rabbits being under inhalation exposure to benzene during 4 months, its concentrations increasing and fluctuating. We determined the following blood parameters: number of reticulocytes, eosinophils, basocytes, and erythrocytes; erythrocytes sedimentation rate; blood clotting period; blood clot retraction; plasma re-calcification period; plasma tolerance to heparin; prothrombin time; prothrombin index; fibrinogen concentration; blood fibrinolytic activity; acetylcholine and choline esterase contents. We also determined adrenalin, noradrenalin, dopamine, and dihydroxyphenylalanine contents in urine. Acute experiments results revealed that one-time exposure to benzene exerted a narcotic effect on the central nervous system which had an excitation phase and inhibition phase. Under a repeat exposure to benzene animals' drug intoxication was shorter. And here neutrophils / leucocytes gradient first increased to 139.5 % from its standards value and then when down under consequent intoxications. We detected relevant changes in morphological picture of animals' peripheral blood and their central and vegetative nervous system under chronic exposure to intermittent and increasing benzene concentrations. So, our research revealed that effects exerted by benzene in small concentrations led to apparent shifts in white blood and catecholamines (adrenalin, noradrenalin, dopamine, and dihydroxyphenylalanine. We also detected certain signs that cate-cholamines endogenous reserves (dihydroxyphenylalanine were depleted and, and also signs of eosinophils-basocytes disso-ciation; such prognostic signs were considered to be unfavorable as it was exactly at that

    New drugs of abuse continue to emerge, including synthetic cannabinoids, synthetic cathinones, and hallucinogens. It is important to recognize their individual psychopharmacologic properties, symptoms of intoxication, and symptoms of withdrawal. Providers must be vigilant of acute medical or psychiatric complications that may arise from use of these substances. Treatment of the patient also includes recognition of any substance use disorders as well as comorbid psychiatric disorders. Although pharmacologic treatments for substance use disorder (of the drugs included in this article) are limited, there are a variety of psychotherapeutic modalities that may be of some benefit.

    Full Text Available The objective was to determine the rate of potential drug-drug interactions in prescriptions for elderly diagnosed with Acute Coronary Syndrome in a teaching hospital. This is an exploratory, descriptive study that analyzed 607 prescriptions through databases to identify and classify the interactions based on intensity (major, moderate or minor, the mechanism (pharmacokinetic or pharmacodynamics and documentation relevance. We detected 10,162 drug-drug interactions, distributed in 554 types of different combinations within the prescribed drugs, and 99% of prescriptions presented at least one and a maximum of 53 interactions; highlighting the prevalence of major and moderates ones. There was a correlation between the number of drug-drug interactions and the number of prescribed drugs and the hospitalization time. This study contributes for the delimitation of a prevalence pattern in drug-drug interactions in prescriptions for Acute Coronary Syndrome, besides subsidizing the importance of the effective implementation of the Clinical Pharmacy in teaching hospitals.

    Cocklebur (Xanthium strumarium) fed to feeder pigs was associated with acute to subacute hepatotoxicosis. Cotyledonary seedings fed at 0.75% to 3% of body weight or ground bur fed at 20% to 30% of the ration caused acute depression, convulsions, and death. Principle gross lesions were marked serofibrinous ascites, edema of the gallbladder wall, and lobular accentuation of the liver. Acute to subacute centrilobular hepatic necrosis was present microscopically. The previously reported toxic principle, hydroquinone, was not recovered from the plant or bur of X. strumarium. Authentic hydroquinone administered orally failed to produce lesions typical of cocklebur intoxication but did produce marked hyperglycemia. Carboxyatractyloside recovered from the aqueous extract of X. strumarium and authentic carboxyatractyloside, when fed to pigs, caused signs and lesions typical of cocklebur intoxication. Marked hypoglycemia and elevated serum glutamic oxaloacetic transaminase and serum isocitric dehydrogenase concentrations occurred in pigs with acute hepatic necrosis that had received either cocklebur seedlings, ground bur or carboxyatractyloside.

    Thallium intoxication was reported in cases with accidental ingestion, suicide attempt, and criminal adulteration. Reported cases were mostly one-time ingestion, therefore, the clinical course of divisional ingestion has not been fully known. Here, we report a case with two-step thallium intoxication manifesting as tardily accelerated neurologic deterioration. A 16-year-old adolescent was cryptically poisoned with thallium sulfate twice at an interval of 52days. After the first ingestion, neurologic symptoms including visual loss, myalgia, and weakness in legs developed about 40days after the development of acute gastrointestinal symptoms and alopecia. After the second ingestion, neurologic symptoms deteriorated rapidly and severely without gastrointestinal or cutaneous symptoms. Brain magnetic resonance imaging exhibited bilateral optic nerve atrophy. Nerve conduction studies revealed severe peripheral neuropathies in legs. Thallium intoxication was confirmed by an increase in urine thallium egestion. Most of the neurologic manifestations ameliorated in two years, but the visual loss persisted. The source of thallium ingestion was unraveled afterward because a murder suspect in another homicidal assault confessed the forepast adulteration. This discriminating clinical course may be attributable to the cumulative neurotoxicity due to the longer washout-time of thallium in the nervous system than other organs. It is noteworthy that the divisional thallium intoxication may manifest as progressive optic and peripheral neuropathy without gastrointestinal or cutaneous symptoms. Copyright © 2016 Elsevier Ltd.

    The high risk behavior of intoxicated drivers, impaired reaction time, lack of seat belt use, and increased incidence of head injury raises questions of whether pre-hospital use of alcohol leads to a higher injury severity score and worse clinical outcomes. We therefore compared intoxicated and non-intoxicated drivers of motor vehicle crashes with respect to outcome measurements and also describe the resources utilized to achieve those outcomes at our Level 1 trauma center. Retrospective descriptive study (Jan 2002-June 2007) of our trauma registry and financial database comparing intoxicated drivers with blood alcohol levels (BAC) > 80 mg/dl (ETOH > 80) with drivers who had a BAC of 0 mg/dl (ETOH = 0). Drivers without a BAC drawn or who had levels ranging from 1 mg/dL to 80 mg/dL were excluded. Data was collected on demographic information (age, gender, injury severity score or ISS), outcome variables (mortality, complications, ICU and hospital LOS, ventilator days) and resource utilization (ED LOS, insurance, charges, costs, payments). p 80; stratified chi square. Out of 1732 drivers, the combined study group (n = 987) of 623 ETOH = 0 and 364 ETOH > 80 had a mean age of 38.8 +/- 17.9, ISS of 18.0 +/- 12.1, and 69.8%% male. There was no difference in ISS (p = 0.67) or complications (p = 0.38). There was a trend towards decreased mortality (p = 0.06). The ETOH = 0 group had more patients with a prolonged ICU LOS (>/= 5 days), ventilator days (>/= 8 days), and hospital LOS (> 14 days) when compared to the ETOH > 80 group (p 80 group tended to be self pay (4.9% vs. 0.7%, p pay, less likely to have charges > $50K, and less likely to pay >/= 90% of the charges. Further research using multivariable analysis is needed to determine if these apparent outcomes differences are driven by acute intoxication, and the tendency for endotracheal intubation and ICU admission, rather than injury severity.

    The influence of blood alcohol level (BAL) on outcome remains unclear. This study investigated the relationships between BAL, type and number of diffuse axonal injury (DAI), intraventricular bleeding (IVB) and 6-month outcome. This study reviewed 419 patients with isolated blunt traumatic brain injury. First, it compared clinical and radiological characteristics between patients with good recovery and disability. Second, it compared BAL among DAI lesions. Third, it evaluated the correlation between the BAL and severity of IVB, number of DAI and corpus callosum injury lesions. Regardless of BAL, older age, male gender, severe Glasgow Coma Scale score (injury lesions. Acute alcohol intoxication was not associated with type and number of DAI lesion, IVB and disability. This study suggested that a specific type of traumatic lesion, specifically lesion on genu of corpus callosum and IVB, might be more vital for outcome.

    Self-report studies indicate that cannabis could increase sexual desire in some users. We hypothesized that intoxication increases activation of brain areas responsive to visual erotica, which could be useful in the treatment of hypoactive sexual desire disorder, a condition marked by a lack of sexual desire. The aim of this study is to assess the aphrodisiacal properties of cannabis. We conducted an open-randomized study with 21 heterosexual casual cannabis users. A 3T MRI was used to measure brain activation in response to erotic pictures. Blood samples were collected to determine the serum levels of cannabinoids, cortisol and prolactin. Participants were grouped according to whether they had ever experienced any aphrodisiacal effects during intoxication (Group A) or not (Group non-A). Intoxication was found to significantly increase activation in the right nucleus accumbens in the Group A while significantly decreasing activation in the Group non-A. There was also a significant interaction between the group and intoxication, with elevated prolactin in the Group non-A during intoxication. No intoxication-related differences in subjective picture evaluations were found. Cannabis intoxication increases activation of the right nucleus accumbens to erotic stimuli. This effect is limited to users whose prolactin is not elevated in response to intoxication. This effect may be useful in the treatment of low sexual desire.

    Patients frequently arrive in emergency departments (EDs) after being resuscitated from opioid overdose. Autopsy studies suggest that multidrug intoxication is a major risk factor for adverse outcomes after acute heroin overdose in patients. If this is true, there may be high-risk drug combinations that identify patients who require more intensive monitoring and prolonged observation. Our objective was to determine the impact of co-intoxication with alcohol, cocaine, or CNS depressant drugs on short-term adverse event rates in patients resuscitated from acute opioid overdose. Data were extracted from the database of a prospective opioid overdose cohort study conducted between May 1997 and 1999. Patients were prospectively enrolled if they received naloxone for presumed opioid overdose. Investigators gathered clinical, demographic, and other predictor variables, including co-intoxicants used. Patients were followed to identify prespecified adverse outcome events occurring within 24 h, and multiple logistic regression was used to determine the association of concomitant drug use on short-term adverse event rates. Of 1155 patients studied, 58 (5%) had pure opioid overdose and 922 (80%) reported co-intoxicants, including alcohol, cocaine, and CNS depressants. Overall, out of 1056 patients with known outcome status there were 123 major adverse events (11.6%) and 194 minor adverse events (18.4%). After adjustment for age, gender, HIV status, cardiovascular disease, pulmonary disease and diabetes, we found that coadministration of alcohol, cocaine, or CNS depressants, alone or in combination, was not associated with increased risk of death or adverse events during the 24 h follow-up period. In patients resuscitated from acute opioid overdose, short-term outcomes are similar for patients with pure opioid overdose and multidrug intoxications. A history of cointoxication cannot be used to identify high-risk patients who require more intensive ED monitoring or prolonged

    Full Text Available OBJECTIVE: To determine the severity of dapsone (DDS acute intoxication – an uncommon medical event – using clinical and laboratory parameters. METHODS: Two hundred and seventy four patients with acute DDS intoxication, aged 1 month to 50 years old, were studied and classified into four age groups. Clinical evaluation was assessed through a protocol and correlated with laboratory parameters. Spectrophotometric methods were used to analyze methemoglobinemia (MHbp and dapsonemia (DDSp.

    Full Text Available Background: Acute rhinosinusitis that usually caused by Streptococcus pneumoniae becomes the reason why patients seek for medical care. Drugs resistance in Streptococcus pneumoniae is increasing worldwide. This study was conducted to determine drugs resistance of Streptococcus pneumonia from acute rhinosinusitis in Dr. Hasan Sadikin General Hospital. Methods: A descriptive laboratory study was conducted in June–October 2014 at the Laboratory of Microbiology Faculty of Medicine Universitas Padjadjaran. The sample was taken using nasopharyngeal swabbing from 100 acute rhinosinusitis patients in Dr. Hasan Sadikin General Hospital and planted on tryptic soy agar containing 5% sheep blood and 5 μg/ml of gentamicin sulphate and then incubated in 5% CO2 incubator at 37°C for 24 hours. The identification of Streptococcus pneumonia was performed by optochin test. The susceptibility test against Streptococcus pneumoniae was done using disk diffusion method.The antibiotic disks were trimethoprim-sulfamethoxazole, oxacillin, levofloxacin, azithromycin, and doxycycline. Results: Out of 100 samples, 8 of them were tested positive for Streptococcus pneumoniae. Three of Streptococcus pneumoniae isolates died with unknown reason after it were stored at -80 .The drugs resistance test showed the resistance of Streptococcus pneumonia to oxacillin, azithromycin and trimethoprim were 6, whereas levofloxacin and doxycycline are 4. Conclusions: Streptococcus pneumonia drugs resistance in acute rhinosinusitis shows the resistance of Streptococcus pneumoniae to oxacillin, azithromycin and trimethoprim are 6, whereas the resistance to levofloxacin and doxycycline are 4.

    Full Text Available Objective. To characterize the clinical and demographic profile of patients hospitalized due to drug intoxication at an intensive care unit (ICU of a teaching hospital between 2004 and 2010. Methodology. In this descriptive study, information was collected from the hospitalized patients, as informed by a Toxicology Care Center (CAT in Paraná (Brazil. The clinical files were checked and information was collected about age, gender, toxic agents and intoxication circumstances, comorbidities and clinical outcomes. Results. Sixty-two patients were included in the study, with a mean age of 58 years and 77% male. Alcohol was the substance related to most hospitalizations (77%, followed by psychoactive drugs (14% and marihuana and crack (5% each. The main comorbidities were bronchopneumonia due to aspiration (37%, alcohol-related liver cirrhosis (24% and traumatic brain injury (19%. The most frequent intoxication circumstances were chronic abuse (79%, attemptive suicide (19% and acute abuse (4.9%. Thirty-nine percent of the patients died during hospitalization. Conclusion. The results show a concerning reality, as most of the patients are men of economically active age, who were intoxicated by a legal substance like alcohol, with a relevant number of deaths. Nurses need to pay particular attention to this health problem, in the context of which they play a fundamental role as educators with a view to the encouragement of healthy lifestyles.

    Synthetic androgens (i. e., anabolic-androgenic steroids) are the primary component to the majority of problematic appearance and performance enhancing drug (APED) use. Despite evidence that these substances are associated with increased risk for aggression, violence, body image disturbances, and polypharmacy and can develop a pattern of chronic use consistent with drug dependence, there are no formal definitions of androgen intoxication. Consequently, the purpose of this paper is to establish a testable theory of androgen intoxication. We present evidence and theorize that synthetic androgen intoxication can be defined by a pattern of poor self-regulation characterized by increased propensity for a range of behaviors (e.g., aggression, sex, drug seeking, exercise, etc.) via androgen mediated effects on general brain arousal. This theory posits that androgens reduce threshold for emotional reactivity, motor response, and alertness to sensory stimuli and disrupt inhibitory control over the behaviors associated with synthetic androgen use. These changes result from alteration to basic neurocircuitry that amplifies limbic activation and reduces top-down cortical control. The implications for this definition are to inform APED specific hypotheses about the behavioral and psychological effects of APED use and provide a basis for establishing clinical, legal, and public health guidelines to address the use and misuse of these substances.

    To describe the treatment of ibuprofen intoxication with therapeutic plasma exchange in a dog (TPE). A 13-year-old male neutered mixed breed dog presented after ingesting approximately 200 mg/kg of ibuprofen. Treatment consisted of supportive medical therapy with IV fluids, gastrointestinal protectants, antiemetics and prostaglandin analogs, and TPE. A cycle of TPE was performed over 180 minutes, achieving 1.5 plasma volume exchanges. During therapy, heparinized blood and effluent samples were collected. Ibuprofen concentrations were determined in the samples by high-pressure liquid chromatography. Post TPE, the dog was continued on supportive medical therapy and was discharged 96 hours after the overdose. This report describes the use of TPE as an adjunct for ibuprofen intoxication. An 85% reduction in plasma ibuprofen concentration occurred and recovery from a potentially lethal ingestion of ibuprofen was achieved with TPE and supportive care. TPE should be considered when presented with acute ibuprofen intoxication due to the rapid and efficacious nature of therapy. © Veterinary Emergency and Critical Care Society 2017.

    2014-05-01

    The aim of the study was to explore differences and similarities between the various non-natural manners of death (accident, suicide, homicide) regarding toxicological findings in illicit drug users. Medicolegal autopsy reports from the Institute of Forensic Medicine University of Oslo concerning deaths from 2000 to 2009 were investigated. Those aged 20-59 whose manner of death was non-natural and who tested positive for any narcotic drug (morphine/heroin, amphetamines, ecstasy, cannabis, LSD, PCP, and high levels of GHB in addition to methadone and buprenorphine) were selected. All substance findings were registered and categorized (narcotics, ethanol, and medicinal products). Of the 1603 autopsies that met the selection criteria, 1204 were accidental intoxications, 122 accidents other than intoxication, 114 suicides by intoxication, 119 non-intoxication suicides, and 44 victims of homicide. Poly drug use was found in all manners of death. The drug profile as well as the mean number of substances (illicit drugs and medicinal products) varied from 2.9 to 4.6 substances per case, depending on the manner of death. Intoxication suicides had the highest number of substances and a total drug profile similar to accidental intoxications. Non-intoxication suicides had a total drug profile similar to homicide and accidents other than intoxication. The number of substances found per case increased during the decade, mainly due to increased findings of methadone, cannabis, amphetamines, and benzodiazepines. Methadone findings increased much more than buprenorphine. Methadone was found 20 times more often than buprenorphine in accidental intoxication cases. In summary, poly drug findings are common in adults who suffer a non-natural death while using illicit drugs. The different manners of death have some specific characteristics and significant differences regarding drug profile. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The antidotal efficacies of chelators during acute cadmium intoxication has previously been examined in experiments where both a soluble cadmium salt and the chelator were administered parenterally. In the present study, PA, DMSA and related compounds were studied as oral antidotes during oral CdCl 2 intoxication. According to the antagonistic effects noted on mortality, peristaltic toxicity and intestinal cadmium uptake, the relative efficacies of the compounds tested were: DMSA>PAD>DMPS>MSA>PA>NAPA. None of the chelators induced major changes in the organ distribution of absorbed cadmium, in particular no increased cerebral deposition of cadmium. This study indicates that, in oral cadmium intoxication in humans, orally administered DMSA would be likely to offer protection against the local toxicity of cadmium in the gastrointestinal tract as well as to reduce the risk of systemic toxicity of absorbed cadmium.

Colchicine inhibits the deposition of uric acid crystals and is an inhibitor of mitosis. Nausea, vomiting, abdominal pain, and diarrhea, with a massive loss of fluid and electrolytes are the first clinical symptoms of colchicine poisoning. Stomach lavage and rapid gastric decontamination with activated charcoal are crucial. An acute dose of about 0.8 mg/kg of colchicine is presumed to be fatal. We report the clinical outcomes of two different cases of colchicine intoxication for attempted suicide. The dose required for morbidity or mortality varies significantly. The dose of 1 mg/kg in the first case was directly related with mortality, while the dose of 0.2 mg/kg in the second was related with survival. The other difference between the patients was the time of arrival to hospital after ingestion. This period was 4 hours for case 1 and only 1, hour for case 2. The initiation of treatment later than 2 hours after ingestion of colchicine may significantly impair treatment because the absorption time for colchicine after oral administration is about 30–120 minutes. The rising lactate level and high anion gap metabolic acidosis in our patient (case 1 were attributed to lactic acidosis, so hemodialysis was performed, and the duration of hemodialysis was prolonged. Lactic acidosis in the first case was one of the reasons for mortality. The most important parameters which define the chance of survival are the dose of ingested drugs and the arrival time to hospital after ingestion. The patients must be monitored closely for lactic acidosis

    This study includes all deaths among drug addicts in the years 1991 (n = 219) and 1992 (n = 214) investigated at the three institutes of forensic medicine in Denmark. The results are compared with deaths among drug addicts in 1984-1985. The number of deaths among drug addicts increased by approximately 50% in 1991-1992 compared with 1984-1985. The increase was most significant among drug addicts over 35 years of age. The cause of death was intoxication in three-quarters of the cases in 1991-1992. In half of these cases heroin/morphine had caused death, while intoxications caused by methadone accounted for approximately 30% of the cases. In the metropolitan area the frequency of methadone intoxications increased significantly compared with 1984-1985, whereas the number of heroin/morphine intoxications did not change. Outside the metropolitan area, however, a significant increase in heroin/morphine intoxications was noticed. In all parts of the country the number of propoxyphene intoxications decreased to a few annual cases. The most commonly used drugs of abuse were heroin/morphine, diazepam and methadone, often in combination with alcohol.

    Although scarce, the data about acute poisonings with psycho-active substances during the period of socioeconomic crisis in Bulgaria indicate the appearance and increase of the use of inhalants, prescribed and over-the-counter medications and the increase of acute poisoning rate with heroin. To ascertain some characteristics of acute poisonings with psycho-active substances in Plovdiv region from 01.01.1990 to 31.12.2000. The whole caseload of 571 acute poisonings with psycho-active substances in Plovdiv region (8.8% of the population of the country) between 1990 and 2000, treated in the only Clinic of Toxicology in the region is studied retrospectively. The variables gender, age, type of psycho-active substance (DSM-IV criteria), grade of severity, duration of use, times of poisoning and some differences between alcohol and opioid poisonings are investigated. Acute poisoning with psycho-active substances are 5.43% of all intoxications. The moderate grade of severity (48.5%), alcohol (62.8%) and opioid (15.3%) intoxications, debut poisoning (86.8%) and poisonings occurring in the initial period of use predominate. An increase of acute poisonings with psycho-active substances in the last third of the studied period (1990-2000) is established--severe forms (2.59 times) and recidivistic intoxication (4 times). Alcohol and opioid poisonings predominate among severe intoxications. The hospital stay is relatively short--1.75 +/- 0.67 and hospital lethality is 1.6%. 1. The moderate grade of severity, alcohol and opioid intoxications (especially in the severe grade cases), occurrence in the initial period of use and relatively short hospital stay predominate in acute poisonings with psycho-active substances in the period of socioeconomic crisis. Hospital lethality (1.6%) is ascertained only in severe alcohol intoxication. 2. An increase of acute poisonings with psycho-active substances--severe forms, mild forms and recidivistic intoxications is established in the last

    Episodes of agitation are frequent in intoxicated patients who have a substance use disorder, a psychiatric disorder or both (dual diagnosis). For managing the agitation, it is necessary to act promptly in a safe environment and addressing any underlying etiology. Inhaled loxapine improves symptoms of agitation in adults with psychiatric disorders (eg, schizophrenia) within 10 minutes of administration. Recently, some reports have documented the usefulness of loxapine in dual diagnoses patients with agitation. However, the efficacy of loxapine in intoxicated patients has not been deeply addressed. This report describes a case series of 12 patients (with addiction or dual disorder) who received inhaled loxapine for symptoms of psychomotor agitation during intoxication with different substances (eg, alcohol, cannabis, or cocaine) at 1 center in Spain. Data from 12 patients were reviewed, 5 patients were attended at the emergency room, 4 at the addiction and dual diagnosis unit, and 3 were treated during hospitalization for detoxification. All patients were under effects of substances. They had substance use disorder (including cannabis, cocaine, alcohol, hypnotics, and hallucinogens), and almost all (90%) presented 1 or more psychiatric disorders. One dose of inhaled loxapine was effective in 9 patients (75%), and in 3 patients, a second dose was required. Only mild dizziness was reported in 1 patient after the second dose. The acute agitation was effectively and quickly managed with inhaled loxapine in all intoxicated patients and enabled the appropriate clinical evaluation of the agitated state and the patient's management.

    This analysis presents the prevalence of substance use among young adolescents. The extent to which factors such as peer behaviour, parenting practices and school commitment and achievement are associated with drinking to intoxication and other drug use is investigated. The data are from the 1998/99 National Longitudinal Survey of Children and Youth. Analysis is based on a cross-sectional file from 4,296 respondents aged 12 to 15. Prevalence estimates for alcohol and drug use were calculated by sex. Logistic regression models were fitted to estimate the odds of drinking to intoxication and drug use, adjusted for socio-demographic factors, peer and parent substance use, parenting practices, school commitment/attachment, emotional health and religious attendance. In general, drinking to intoxication and drug use were more common among 14- and 15-year-olds than among 12- and 13-year-olds. The odds of drinking to intoxication and drug use were highest among adolescents whose friends used alcohol or drugs or were often in trouble, who reported low commitment to school, or whose parents had a hostile and ineffective parenting style.

    Toluene, formerly known as toluol, is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is sometimes also used as an inhalant drug for its intoxicating properties. It has potential to cause multiple effects in the body including death. I report a case of a 27-year-old male, chronic spray paint sniffer, who presented with severe generalized muscle weakness and developed acute respiratory failure requiring ventilatory support. Toluene toxicity was confirmed with measurement of hippuric acid of 8.0 g/L (normal <5.0 g/L). Acute respiratory failure is a rare complication of chronic toluene exposure that may be lethal if it is not recognized immediately. To our knowledge, this is the second case of acute respiratory failure due to toluene exposure.

    Determine the relationship of subjective intoxication to blood alcohol concentration (BAC) and examine whether patron and event-level characteristics modify the relationship of BAC to subjective intoxication. An in-situ systematic random sample of alcohol consumers attending night-time entertainment districts between 10pm and 3am on Friday and Saturday nights in five Australian cities completed a brief interview (n=4628). Participants reported age, sex, and pre-drinking, energy drink, tobacco, illicit stimulant and other illicit drug use that night, and their subjective intoxication and BAC were assessed. Male and female drinkers displayed equally low sensitivity to the impact of alcohol consumption when self-assessing their intoxication (BAC only explained 19% of variance). The marginal effect of BAC was not constant. At low BAC, participants were somewhat sensitive to increases in alcohol consumption, but at higher BAC levels that modest sensitivity dissipated (actual BAC had less impact on self-assessed intoxication). The slope ultimately leveled out to be non-responsive to additional alcohol intake. Staying out late, pre-drinking, and being young introduced biases resulting in higher self-assessed intoxication regardless of actual BAC. Further, both energy drinks and stimulant use modified the association between BAC and perceived intoxication, resulting in more compressed changes in self-assessment as BAC varies up or down, indicating less ability to perceive differences in BAC level. The ability of intoxicated patrons to detect further intoxication is impaired. Co-consumption of energy drinks and/or stimulant drugs is associated with impaired intoxication judgment, creating an additional challenge for the responsible service and consumption of alcohol.

Currently neuroprotective and neuroregenerative effects of lithium are of interest as in case of acute brain injury, also in chronic neurodegenerative diseases such as dementia, alcoholism, Alzheimer disease, etc. [1–5]. In clinical practice use of lithium preparations is limited due to difficult adjustment of drug dosage, necessity of monitoring its concentration in blood, side effects development as a result of accumulation of lithium in a body. For the purpose of improvement of pharmacologic properties lithium is combined with other agents (for example modifying sorbent thus it can produce longer-term and more harmless (less side reactions effect in the long view. Lithium immobilization on sorption basis will allow to use sorbent as detoxicant and carrying agent of drugs to body. The purpose of the work is studying the effect of the lithium – containing sorbent on terms of behavioral reactions under chronic alcohol intoxication model.Materials and methods. During the work we used nonlinear mice – males, which weight 25–30 g (180 animals. Chronic alcohol intoxication was precipitated via 40% proof spirit injections (oral supplementation in quantity of 3 g/kg during 2 weeks, additionally mice drunk 5% proof spirit from drinking bowl. Each experimental group consisted of 10 animals. Study drugs were inserted inside while ethanol injecting. Control animals were inserted 0,9% salin solution. Emotional state of animals was assessed through forced swim test, short – term memory assessment was performed through conditioned passive avoidance reflex. Effect of chronic alcohol intoxication on the parameters of conditioned reflex activity was measured every 7 days.Results. It was found that the investigated lithium-containing sorbent increases: the number of mice are trained passive avoidance reflex, remembering percent of electric shock

    Intravenous lead administration to dogs produced an acute syndrome of lead intoxication charcterized by depression, vomiting, anorexia and weight loss. The effect of chelation therapy with calcium disodium ethylene diamine tetraacetate, penicillamine or both was determined by serially monitoring changes in blood lead and urine delta-aminolevulinic acid. Following therapy, blood lead values were significantly lower in chelated dogs than non-treated lead exposed dogs on days 7 and 10. Urine delta-aminolevulinic acid at day 7 was significantly higher in untreated lead exposed dogs than in other groups. There was no significant difference in blood lead or urine delta-aminolevulinic acid between lead intoxicated dogs which underwent the indicated chelation therapy protocols. There was, however, a trend for higher urinary delta-aminolevulinic acid excretion in those intoxicated dogs undergoing calcium disodium ethylene diamine tetraacetate therapy as opposed to those undergoing penicilamine therapy. There was no significant correlation between blood lead and urinary delta-aminolevulinic acid previous to lead exposure. However, after lead exposure significant correlation was present at days 4, 7, 10 and 14. Certain lead exposed dogs following chelation therapy were noted to have normal blood lead levels but elevated urinary delta-aminolevulinic acid suggesting that blood lead does not always correlate with metabolic effects of lead in the body. Urinary delta-aminolevulinic acid was therefore recommended as an additional laboratory parameter which improved assessment of lead exposure in dogs, particularly in determining adequacy of chelation therapy.

    A red fox (Vulpes vulpes) and a European badger (Meles meles) were found dead on a golf-course in October 1997 near Stockholm (Sweden). At necropsy, both animals were obese and the main finding was acute circulatory collapse. Theobromine intoxication was suspected as chocolate waste was available at a nearby farm and no other cause of death could be detected. Gastric contents and samples of liver from both animals were analyzed by reversed-phase high pressure liquid chromatography for the presence of methylxanthines. Theobromine and caffeine were detected in gastric contents and theobromine was identified in the liver samples from both animals. This appears to be the first report of theobromine intoxication in the red fox and the European badger.

    Paraquat is considered to be the main pesticide involved in accidental and intentional poisoning, and is responsible for a high rate of morbidity and mortality. The aim of this study is to present a comprehensive bibliometric analysis of paraquat intoxication-related research. Data was retrieved in March 2017 from the Scopus database. An overview of the research on paraquat intoxication was presented alongside the information related to several bibliometric indicators, such as research trends, countries with their h-index, collaboration, hot issues, top-cited publications, journals, and institutions. There were 1971 publications related to paraquat intoxication in the Scopus database that were published between 1966 and 2015. There was increasing research output in the field of paraquat intoxication during the period 2006-2015. The USA published the highest number of publications (n = 338), followed by Japan with 228 publications, and China with 159 publications. The USA and the UK achieved the greatest h-index values (h-index values of 49 and 31, respectively). The USA also achieved the highest number of publications involving international collaboration, with 55 publications, followed by the UK, with 18 publications. The most prevalent topics in this field were "acute paraquat intoxication," "toxic effects of paraquat to the lung," and "mechanism of paraquat toxicity." Although a substantial amount of research has been produced on paraquat intoxication for most developed countries, there are research gaps regarding the international research agenda in this research area. The findings could be applied for prioritizing and organizing future research efforts related to paraquat toxicity. © 2018 Wiley Periodicals, Inc.

    In Japan, synthetic drugs have emerged since late 2000s, and cases of emergency visits and fatal traffic accidents due to acute intoxication have rapidly increased. The synthetic drugs gained popularity mainly because they were cheap and thought to be "legal". The Japanese government restricted not only production and distribution, but also its possession and use in April 2014. As the synthetic drug dependent patients have better social profiles compared to methamphetamine abusers, this legal sanction may have triggered the decrease in the number of synthetic drug dependent patient visits observed at Kanagawa Psychiatric Center since July 2014. Treatment of the synthetic drug dependent patients should begin with empathic inquiry into the motives and positive psychological effects of the drug use. In the maintenance phase, training patients to trust others and express their hidden negative emotions through verbal communications is essential. The recovery is a process of understanding the relationship between psychological isolation and drug abuse, and gaining trust in others to cope with negative emotions that the patients inevitably would face in their subsequent lives.

    Full Text Available Drug-induced acute necrotizing pancreatitis is a rare adverse event, although it has been reported in association with different drugs, including non-steroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and analgesic agents commonly used in rheumatology. In different reviews of the pancreotoxicity of drugs, infliximab and etanercept are mentioned among all medications implicated in drug-induced pancreatitis, but clinical cases of acute pancreatitis complicating treatment with these anti-TNF-α agents have been exceptionally reported. We describe a patient with ankylosing spondylitis treated with etanercept, who developed an acute fulminant necrotizing pancreatitis that resulted in death. Doctors should pay close attention to patients taking biologic drugs in which a complaint of abdominal pain lasting for several days with no apparent cause may require a prompt referral for medical consultation.

    Full Text Available Background: Homoeopathic drugs are frequently recommended in day to day life as therapeutic agents by homoeopathic practitioners. However, safety of homoeopathic drugs remains a challenge because of the high variability of chemical components involved. Aim: The objective of the present study was to investigate the acute, subacute, and chronic oral toxicity of different homoeopathic drugs (Ferrum phosphoricum 3X, Ferrum phosphoricum 6X, Calcarea phosphoricum 6X, and Magnesium phosphoricum 6X in experimental models. Materials and Methods: In acute oral toxicity study, homoeopathic drugs were administered orally at 2000mg/kg body weight, and animals were observed for toxic symptoms till 10 days as per the OECD guidelines. For subacute and chronic toxicity study, homoeopathic drugs were administered for 28 and 180 days, respectively, as per the OECD guidelines. At the end of 28 and 180 days, the animals were sacrificed and toxicity parameters were assessed. Histopathological evaluation of different organs was also performed to assess any toxicity. Results: In acute toxicity study, no mortality was found at a dose of 2000 mg/kg which indicates that oral LD50of homoeopathic drugs were more than 2000 mg/kg. The administration of drugs at a dose of 70 mg/kg body weight for 28 and 180 days did not produce any significant change in haematological and biochemical parameters of male and female rats as compared to normal control group. No pathological changes were observed in histology of various organs of treated rats as compared to normal control animals. Conclusion: These homoeopathic drugs are safe & produce no toxicity when administered for longer duration.

    Full Text Available Objective: to examine the capacities of pharmacological correction of impairments in oxygen-transporting systems and metabolic processes with perfluorane and cytoflavin in critically ill patients with acute intoxication with neurotropic poisons.Subjects and methods. Metabolic sequels of severe hypoxia, free radical processes, and endogenous intoxications were studied in 62 patients with the severest acute intoxication with neurotropic poisons.Results. The studies have established that hypoxia and metabolic changes lead to the development of endotoxicosis. Intensifying endotoxicosis in turn enhances hypoxic lesion. Thus, the major task of intensive care is to restore oxygen delivery and to diminish metabolic disturbances and endotoxicosis. Ways of correcting hypoxia and metabolic disturbances are considered in the severe forms of acute poisoning.

    Investigation of hydroxylamine sulfate toxicity mechanism in vivo and estimation of α-tocopherol acetate and methylene blue efficiency in poisoning treatments. In vivo experiments were conducted on 102 Wistar Han rats. The experiments investigated the hematotoxic and oxidative stress effects of hydroxylamine sulfate in acute and subacute toxicity treatment of animals. Electron Spin Resonance was used for quantitative determination of blood and liver tissue parameters alterations after intoxication. The osmotic fragility of erythrocytes, lipid peroxidation intensity and level of SH-groups in liver of rats were determined by established biochemical assays. Hydroxylamine sulfate cause an acute hematotoxicity and oxidative stress in vivo as demonstrated by the appearance of free oxidized iron in blood, reduced glutathione content and increased lipid peroxidation in liver. The experimental studies showed the formation of Hb-NO, MetHb in erythrocytes and as well of stable complex of reduced iron (Fe(2+)) with hydroxylamine sulfate. Methylene blue treatment does not reduce the Hb-NO or MetHb levels in intoxicated animals while administration of α-tocopherol acetate reduces substantially lipid peroxidation. Oxidative stress is a key mechanism of acute hematotoxicity caused by hydroxylamine sulfate. Methylene blue is not suitable antidote in case of hydroxylamine intoxication.

    The changes in the particular number of animals in two groups of 40 rats each subjected to intoxication experiments with beryllium sulphate was investigated. The two investigations had very different characteristics. In the case of chronic intoxication there was a marked lethality over given time intervals. In the case of subacute intoxication the number of animals decreased with time. It was found empirically that this change can be described by an exponential relationship which lends itself to statistical interpretation. (author)

    Objective: To assess the extent of drug induced nephrotoxicity in laboratory animals for determining the role and extent of iatrogenic kidney damage in patients exposed to nephrotoxic drugs in various clinical setups. Study Design: Randomized control trail. Place and Duration of study: Pharmacology department and animal house of Army Medical College from Jan 2011 to Aug 2011. Material and Methods: Thirty six mixed breed rabbits were used in this study. Animals were randomly divided into six groups consisting of six rabbits in each. Groups were named A, B, C, D, E and F. Group A was control group. Group B was given 0.9% normal saline. Group C rabbits were given acute nephrotoxic single dose of amphotericin B deoxycholate. Group D received 0.9% normal saline 10ml/kg followed by amphotericin B infusion. Group E was injected acute nephrotoxic regimen of cyclosporine and amphotericin B infusion. Group F received saline loading along with acute nephrotoxic regimen of cyclosporine and amphotericin B infusion. Results: Biochemical and histopathological analysis showed significant kidney injury in rabbits exposed to acute nephrotoxic doses of amphotericin B and cyclosporine. Toxicity was additive when the two drugs were administered simultaneously. Group of rabbits with saline loading had significantly lesser kidney damage. Conclusion: Iatrogenic acute kidney damage is a major cause of morbidity in experimental animals exposed to such nephrotoxic drugs like amphotericin B and cyclosporine, used either alone or in combination. Clinical studies are recommended to assess the extent of iatrogenic renal damage in patients and its economic burden. Efficient and cost effective protective measure may be adopted in clinical setups against such adverse effects. (author)

    This study examines the physiologic effects of prolonged conducted electrical weapon (CEW) exposure on alcohol-intoxicated adult subjects. Adult volunteers were recruited at a TASER International training conference. All subjects ingested mixed drinks until clinical intoxication or until a minimum breath alcohol level of 0.08 mg/dL was achieved. Blood samples for venous pH, Pco(2), bicarbonate, and lactate were measured in all subjects at baseline, immediately after alcohol ingestion, immediately after exposure to a 15-second TASER X26 discharge (Taser International Inc, Scottsdale, AZ), and 24 hours post-alcohol ingestion. Laboratory values were compared at sampling times using repeated-measure analysis of variance. A focused analysis comparing time points within groups was then performed using paired t tests. Twenty-two subjects were enrolled into the study. There was a decrease in pH and bicarbonate and an increase in lactate after alcohol ingestion. There was a further increase in lactate and drop in pH after CEW exposure. No subject experienced a significant adverse event. All values had returned to baseline levels at 24 hours except lactate, which demonstrated a small but clinically insignificant increase. Prolonged continuous CEW exposure in the setting of acute alcohol intoxication has no clinically significant effect on subjects in terms of markers of metabolic acidosis. The acidosis seen is consistent with what occurs with ethanol intoxication or moderate exertion. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    Psychosis can be associated with acute recreational drug and novel psychoactive substance (NPS) toxicity. However, there is limited data available on how common this is and which drugs are most frequently implicated. We describe a European case series of psychosis associated with acute recreational drug toxicity, and estimate the frequency of psychosis for different recreational drugs. The European Drug Emergencies Network (Euro-DEN) collects data on presentations to Emergency Departments (EDs) with acute recreational drug and NPS toxicity at 16 centres in ten countries. Euro-DEN data from October 2013 through September 2014 was retrospectively searched, and cases with psychosis were included. The proportion of cases with psychosis per drug was calculated in the searched Euro-DEN dataset. Psychosis was present in 348 (6.3 %) of 5529 cases. The median (interquartile range) age was 29 (24-38) years, 276 (79.3 %) were male and 114 (32.8 %) were admitted to psychiatric ward. The drugs most commonly reported were cannabis in 90 (25.9 %) cases, amphetamine in 87 (25.0 %) and cocaine in 56 (16.1 %). More than one drug was taken in 189 (54.3 %) cases. Psychosis was frequent in those ED presentations involving tryptamines (4/7; 57.1 %), methylenedioxypyrovalerone (MDPV) (6/22; 27.3 %), methylphenidate (6/26; 23.1 %), lysergic acid diethylamide (LSD) (18/86; 20.9 %), psilocybe mushrooms (3/16; 18.8 %), synthetic cannabinoid receptor agonists (4/26; 15.4 %) and amphetamine (87/593; 14.7 %), but less common in those involving mephedrone (14/245; 5.7 %), methylenedioxymethamphetamine (MDMA) (20/461; 4.3 %) and methedrone (3/92; 3.3 %). Amphetamine was the most frequent drug associated with psychosis when only one agent was reported, with psychosis occurring in 32.4 % of these presentations. The frequency of psychosis in acute recreational drug toxicity varies considerably between drugs, but is a major problem in amphetamine poisoning. In rapidly changing drug markets and

    Sterile abscess formation in the dog is accompanied by a large increase in output of urinary nitrogen and also by a small but definite increase in the blood non-protein nitrogen. All this nitrogenous material of course is derived from body protein injury and autolysis. Septic inflammation in the dog (pleurisy, pneumonia, peritonitis, etc.) likewise shows a distinct rise in the blood non-protein nitrogen. This rise is not often so great as that frequently observed in the intoxication of intestinal obstruction. Many acute infections in man (septicemia, peritonitis, pneumonia, etc.) show a definite rise in the non-protein nitrogen and urea nitrogen of the blood; some cases show a very great rise above normal (over 100 mg. of non-protein nitrogen per 100 cc. of blood). There may be no anatomical change in the kidney beyond the familiar picture of cloudy swelling. This does not exclude the possibility of some transient functional derangement of the kidney epithelium. Certain obscure intoxications in man may show a considerable rise in the non-protein nitrogen of the blood, indicating a large amount of protein disintegration. These findings must be taken into account in any clinical analysis and interpretation of high non-protein nitrogen of the blood in pathological conditions. PMID:19868253

    Xingnaojing Injection (XNJI) is a modern Chinese formula came from famous Chinese medicine An Gong Niu Huang Pill. XNJI has been used for treatment of cerebral diseases and stroke in China, and is approved by the State Food and Drug Administration of China for the treatment of acute alcohol intoxication (AAI). XNJI belongs to the ethnopharmacological family of medicines. In this study, we investigated the mechanisms of the XNJI effect on AAI. To investigate the effects of XNJI on glutamate, gamma-aminobutyric acid (GABA) and related receptor in lateral hypothalamic area (LHA) of AAI rat. Adult male Sprague-Dawley rats were implanted with microdialysis probes in LHA. Rats were randomly divided into control, model, 1.36mg/kg XNJI, 0.68mg/kg XNJI and 0.34mg/kg XNJI groups. During microdialysis, baseline samples were collected from 1h to 2.5h; thereafter, the rats were given an intraperitoneal injection of 52% ethanol, 5.2g/kg, or saline for control group. Twenty minutes later, three doses of XNJI was given by unilateral injection respectively, while saline for control and model groups, and samples were collected for the next 4h. The extracellular glutamate and GABA levels were measured in the LHA by a high performance liquid chromatography coupled with fluorescence detector (HPLC-FLU). The expression levels of related receptors N-methyl-d-aspartate receptor (NR) subunit NR2A, NR2B and GABAA were analyzed by reverse transcription polymerase chain reaction (RT-PCR). Ethanol (5.2g/kg) significantly decreased the extracellular levels of glutamate and increased extracellular GABA in LHA. On the other hand ethanol significantly decreased NR2A and NR2B mRNAs expression, and increase GABAA mRNA expression. XNJI could increase the extracellular level of glutamate and decrease that of GABA; moreover, induced an increase in NR2A and NR2B mRNA expression, and a decrease in GABAA mRNA expression in LHA. The current changes in glutamate, GABA and mRNA expressions of related

    Full Text Available Encephalitis presents with seizures in the acute phase and increases the risk of late unprovoked seizures and epilepsy. This study aimed to evaluate the effect of antiepileptic drugs in pediatric patients with acute seizures due to encephalitis and epilepsy.Cases of acute pediatric encephalitis between January 2000 and December 2010 were reviewed. Clinical data, including onset at age, seizure type, seizure frequency, effects of antiepileptic drugs, and prognosis were analyzed.During the study period, 1038 patients (450 girls, 588 boys were enrolled. Among them, 44.6% (463 had seizures in the acute phase, 33% had status epilepticus, and 26% (251 developed postencephalitic epilepsy. At one year of follow-up, 205 of the 251 patients with postencephalitic epilepsy were receiving antiepileptic drugs while 18% were seizure free even after discontinuing the antiepileptic drugs. Among those with postencephalitic epilepsy, 67% had favorable outcomes and were using <2 anti-epileptic drugs while 15% had intractable seizures and were using ≥ 2 antiepileptic drugs. After benzodiazepines, intravenous phenobarbital was preferred over phenytoin as treatment of postencephalitic seizures in the acute phase. For refractory status epilepticus, high-dose topiramate combined with intravenous high-dose phenobarbital or high-dose lidocaine had less side effects.Children with encephalitis have a high rate of postencephalitic epilepsy. Phenobarbital and clonazepam are the most common drugs used, alone or in combination, for postencephalitic epilepsy.

    Full Text Available Acute digoxin intoxication is a life-threating condition associated with severe cardiotoxicity. Female gender, age, low lean body mass, hypertension, and renal insufficiency may worsen the prognosis. Arrhythmias caused by digitalis glycosides are characterized by an increased automaticity coupled with concomitant conduction delay. Bidirectional tachycardia is pathognomonic of digoxin intoxication, but it is rarely observed. An 83-year-old woman was admitted to the Emergency Department after self-administration of 5 mg of digoxin i.v. for suicidal purpose. Her digoxin serum concentration was 17.4 ng/mL. The patient developed a bidirectional tachycardia and the Poison Control Center of the hospital provided digoxin immune fab. Bidirectional tachycardia quickly reversed and the patient remained stable throughout the hospital stay. This case shows that a multiple disciplinary approach, involving cardiologists and toxicologists, is essential for the management of digoxin intoxication. The optimal treatment of this rare event depends on the clinical conditions and on the serum drug concentration of the patient. Digoxin immune fab represents a safe, effective, and specific method for rapidly reversing digitalis cardiotoxicity and should be started as soon as the diagnosis is defined.

    Techniques of fetal monitoring, including fetal blood sampling in utero, were employed to study the physiological effects of acute maternal carbon monoxide intoxication on nine term-pregnant female rhesus monkeys exposed to 0.1 to 0.3% inspired carbon monoxide over 1 to 3 hr. The mothers tolerated carboxyhemoglobin levels exceeding 60% without clinical sequelae, whereas the fetuses promptly developed profound hypoxia upon exposure of the mothers to CO. The fetal COHb levels rose only gradually over 1 to 3 hr, and thus contributed only slightly to the development of early fetal hypoxia. The fetal hypoxia was associated with bradycardia, hypotension, and metabolic and respiratory acidosis. Severity of intrauterine hypoxia was closely correlated with the appearance of brain damage. Brain swelling associated with hemorrhagic necrosis of the cerebral hemispheres (severe brain damage) appeared only in fetuses whose arterial oxygen content was reduced below 1.0 ml/100 ml for at least 45 min during the maternal CO intoxication.

    Background The leading cause of injury death among adults in Connecticut (CT), USA is drug poisonings. We analyzed the epidemiology and geographic distribution of opioid-involved accidental drug-involved intoxication deaths (“overdoses”) in CT over an 11-year period. Methods We reviewed data from 1997 to 2007 on all adult accidental/undetermined drug intoxication deaths in CT that were referred to the Office of the Chief Medical Examiner (OCME). Regression analyses were conducted to uncover risk factors for fatal opioid-involved intoxications and to compare heroin- to prescription opioid- and methadone-involved deaths. Death locations were mapped to visualize differences in the geographic patterns of overdose by opioid type. Results Of the 2900 qualifying deaths, 2231 (77%) involved opioids. Trends over time revealed increases in total opioid-related deaths although heroin-related deaths remained constant. Methadone, oxycodone and fentanyl, the most frequently cited prescription opioids, exhibited significant increases in opioid deaths. Prescription opioid-only deaths were more likely to involve other medications (e.g., benzodiazepines) and to have occurred among residents of a suburban or small town location, compared to heroin-involved or methadone-involved deaths. Heroin-only deaths tended to occur among non-Whites, were more likely to involve alcohol or cocaine and to occur in public locations and large cities. Conclusions The epidemiology of fatal opioid overdose in CT exhibits distinct longitudinal, risk factor, and geographic differences by opioid type. Each of these trends has implications for public health and prevention efforts. PMID:21131140

    Caffeine is widely available in beverages and over-the-counter products; however, in large doses, it can lead to lethal arrhythmia. This study aims to clarify the characteristics of caffeine intoxication-related deaths in Tokyo, Japan. Among the 4754 forensic autopsy cases between 2008 and 2013 in which a toxicological investigation was performed, cases in which the blood concentration of caffeine exceeded toxic levels (15 μg/ml) were selected (N = 22). We examined subjects' ages, medical histories, direct/underlying causes of death, and manner of death. We also assessed concurrent drug substance detection and identified the origin of the caffeine. More than 60% of the subjects were between the ages of 20 and 49 years (n = 14, 63.6%). Sixteen cases (72.7%) showed a history of psychiatric diseases such as depression and sleep disorders. The underlying cause of death for all cases except two was caffeine intoxication, and manner of death was classified as undetermined (n = 11), accidental (n = 7), suicide (n = 2), or others (n = 2). Toxicological analysis revealed the presence of ingredients common to analgesics/cold remedies in 12 cases (54.5%). The origin of the caffeine was identified in 11 cases (50.0%); the proportion of identification was significantly lower among the cases in which analgesic/cold remedy ingredients were not detected (20.0%). Caffeine intoxication-related deaths mainly occurred in young and middle-aged persons with common psychiatric diseases. Psychiatrists should take note of caffeine dependence while diagnosing common psychiatric symptoms. In half of the cases, the origin of the caffeine was unidentified; nevertheless, dietary sources or over-the-counter drugs containing caffeine were suspected. As it becomes easier to obtain caffeinated products, continuous monitoring of the number of deaths from caffeine intoxication, in addition to detailed investigations of the caffeine's origin, will be necessary.

  20. Psychiatric and Medical Management of Marijuana Intoxication in the Emergency Department

    Full Text Available We use a case report to describe the acute psychiatric and medical management of marijuana intoxication in the emergency setting. A 34-year-old woman presented with erratic, disruptive behavior and psychotic symptoms after recreational ingestion of edible cannabis. She was also found to have mild hypokalemia and QT interval prolongation. Psychiatric management of cannabis psychosis involves symptomatic treatment and maintenance of safety during detoxification. Acute medical complications of marijuana use are primarily cardiovascular and respiratory in nature; electrolyte and electrocardiogram monitoring is indicated. This patient’s psychosis, hypokalemia and prolonged QTc interval resolved over two days with supportive treatment and minimal intervention in the emergency department. Patients with cannabis psychosis are at risk for further psychotic sequelae. Emergency providers may reduce this risk through appropriate diagnosis, acute treatment, and referral for outpatient care.

    Technetium-99m pyrophosphate (Tc-PYP) imaging was performed in five patients with acute renal failure associated with nontraumatic rhabdomyolysis. Four patients had phencyclidine intoxication and one had viral pneumonia. During the acute phase, marked uptake of pyrophosphate was seen in all patients in several muscle groups, but always in the thigh adductors. The results show that phencyclidine intoxication can result in diffuse muscle uptake of Tc-PYP without overt evidence of muscle injury. Tc-PYP imaging may provide a clue to the cause of acute renal failure in patients with suspected rhabdomyolysis in whom elevations of serum creatine phosphokinase concentrations are equivocal.

  7. Acute Respiratory Failure in Acute Poisoning by Neutrotropic Substances

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV. The patients were divided into 3 groups: 1 those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2 those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3 seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.

    This article describes a case of massive mortality among horses which was probably due to intoxication by pyrrolizidine alkaloids from Heliotropium indicum. Over 4 years more than 75% of a population of about 110 horses on a farm in Costa Rica died after showing nervous neurological symptoms. Two clinical manifestations were encountered, an acute and a chronic one, both with a fatal outcome. Pathological findings in 2 horses coincided with those reported in the literature for intoxication by pyrrolizidine alkaloids and were not specific for VEE. However Venezuelan equine encephalitis (VEE) was the main differential diagnosis and could not completely be excluded because this disease was endemic in the region and VEE titres were found to be high. Taxonomic and toxicological investigations implicated Heliotropium indicum as the most probable principal cause of the intoxication.

    Full Text Available Carbon tetrachloride (CCl4 is an efficient but highly toxic solvent, used in households and commercially in the industry under regulatory surveillance to ensure safety at the working place and to protect the workers’ health. However, acute unintentional or intentional intoxications by CCl4 may rarely occur and are potentially life-threatening. In this review article, therapy options are discussed that are based on a literature review of traditional poisoning cases and the clinical experience with 16 patients with acute poisoning by CCl4. Among various therapy options, the CO2-induced hyperventilation therapy will be considered in detail as the most promising approach. This special therapy was developed because only around 1% of the intoxicating CCl4 is responsible for the liver injury after conversion to toxic radicals via microsomal cytochrome P450 2E1 whereas 99% of the solvent will leave the body unchanged by exhalation. Therefore, to enhance CCl4 elimination through the lungs, CO2 is added to the inspiration air at a flow rate of 2–3 L min−1 in order to achieve hyperventilation with a respiratory volume of 25–30 L min−1. Under this therapy, the clinical course was favorable in 15/16 patients, corresponding to 93.8%. In essence, patients with acute CCl4 intoxication should be treated by forced ventilation.

    For 101 hospitalized patients where clinical symptoms of a glucosidine intoxication as a consequence of oral digoxin treatment were noted, serum digoxin levels were determined using a RIA kit of the Boehringer company (I-125 tracer, solid phase tube separation technique) on a fasted stomach prior to oral drug administration. An ECG was performed simultaneously and in addition kidney function parameters and electrolyte levels were determined. An anamnesis and clinical examination of the patients were also conducted. Interferences in the RIA method and gastro-intestinal illness resulting in changes in resorption behaviour were excluded. The group of patients showed collectively an average serum digoxin level of 2.9 +- 0.9 ng/ml with a range from 1.8 to 6.8 ng/ml, which was statistically significantly higher than the average value for 101 patients receiving long-term oral medication but without symptoms of glycosidine intoxication. According to the manufacture's specifications for the RIA kit, values > 2.0 ng/ml are considered as toxic, with values between 1.6 and 2.0 ng/mg falling into a ''grey zone''. A correlation was found between toxic serum values with changes in ECG pattern and subjective clinical symptoms of intoxication. A limitation of kidney function was responsible for the high serum glycoside levels in 62% of the patients. It was shown that the differing response of patients towards digitalis medication, above all in the case of long-term therapy, warrants an RIA determination of serum glycoside values in order to adjust the digoxin dose to individual requirements.

    Full Text Available Local treatment of 30 preschool children suffe­ring from acute respiratory diseases, acute catarrhal tonsillopha­ryngitis was conducted using the drug Horlospas for Children, which is a metered dose spray containing sea salt, colloidal silver, chlorhexidine bigluconate, marigold and sage extracts, eucalyptus and mint essential oils. A notable acceleration of inflammation regression and a significant decrease in the number of complications after acute respiratory disease were registered. The use of combined drug Horlospas for Children has reduced the number of catarrhal tonsillopharyngitis episodes in the winter, even in sickly children of preschool age.

    To study the lead excretion effect of the chelator Zn-DTPA on the lead intoxication mice, inductively coupled plasma mass spectrometry (ICP-MS) was applied to detect the lead content of biological samples. The acute lead intoxication mice model was established by injecting lead acetate intraperitoneally with the dose of 1 mg. Zn-DTPA was administered intraperitoneally to mice once daily for five consecutive days 4 h after intoxication. Control group, model group, combination of Zn-DTPA and Ca-DTPA group were evaluated at the same time. The urine was collected every day. The mice were sacrificed in batches in the 2rd, 4th, 6th day. Biological samples including urine, whole blood, femur and brain were prepared and nitrated. Lead concentration was detected by ICP-MS. The result showed that Zn-DTPA could increase lead content in urine markedly and reduce lead content in blood, femur and brain.

    In acute psychiatric services, rapid and accurate detection of psychoactive substance intake may be required for appropriate diagnosis and intervention. The aim of this study was to investigate the relationship between (a) drug influence as assessed by physicians and (b) blood drug concentrations among patients admitted to acute psychiatric wards. We also explored the possible effects of age, sex, and psychotic symptoms on physician's assessment of drug influence. In a cross-sectional study, the sample comprised 271 consecutive admissions from 2 acute psychiatric wards. At admission, the physician on call performed an overall judgment of drug influence. Psychotic symptoms were assessed with the positive subscale of the Positive and Negative Syndrome Scale. Blood samples were screened for a wide range of psychoactive substances, and quantitative results were used to calculate blood drug concentration scores. Patients were judged as being under the influence of drugs and/or alcohol in 28% of the 271 admissions. Psychoactive substances were detected in 56% of the blood samples. Altogether, 15 different substances were found; up to 8 substances were found in samples from 1 patient. Markedly elevated blood drug concentration scores were estimated for 15% of the patients. Physician's assessment was positively related to the blood drug concentration scores (r = 0.52; P < 0.001), to symptoms of excitement, and to the detection of alcohol, cannabis, and amphetamines. The study demonstrates the major impact of alcohol and drugs in acute psychiatric settings and illustrates the challenging nature of the initial clinical assessment.

    Full Text Available Abstract Background Cannabis intoxication is related to a number of physical and mental health risks with ensuing social costs. However, little attention has been given to the investigation of possible pharmacological interactions in this condition. Objective To review the available scientific literature concerning pharmacological interventions for the treatment of the acute effects of cannabis. Methods A search was performed on the Pubmed, Lilacs, and Scielo online databases by combining the terms cannabis, intoxication, psychosis, anxiety, and treatment. The articles selected from this search had their reference lists checked for additional publications related to the topic of the review. Results The reviewed articles consisted of case reports and controlled clinical trials and are presented according to interventions targeting the physiological, psychiatric, and cognitive symptoms provoked by cannabis. The pharmacological interventions reported in these studies include: beta-blockers, antiarrhythmic agents, antagonists of CB-1 and GABA-benzodiazepine receptors, antipsychotics, and cannabidiol. Conclusion Although scarce, the evidence on pharmacological interventions for the management of cannabis intoxication suggests that propanolol and rimonabant are the most effective compounds currently available to treat the physiological and subjective effects of the drug. Further studies are necessary to establish the real effectiveness of these two medications, as well as the effectiveness of other candidate compounds to counteract the effects of cannabis intoxication, such as cannabidiol and flumazenil.

    Using a social transmission of food preference paradigm in rats, we previously demonstrated that ethanol (EtOH) exposure during adolescence, as either an observer (interaction with an intoxicated conspecific) or demonstrator (intragastric infusion with EtOH), altered the reflexive odor-mediated responses to the drug. The 2 modes of exposure were equivalent in the magnitude of their effects. Human adolescents, however, are likely to experience the drug in a social setting as both an EtOH observer and demonstrator. That is, both interacting with an intoxicated peer and experiencing EtOH's postingestive consequences in conjunction with hematogenic olfaction. Therefore, we tested whether combined adolescent exposure as both an observer and demonstrator differed from either form of individual experience. Beginning on postnatal day (P) 29, naïve rats received EtOH or water exposures in a social interaction paradigm as either an observer, a demonstrator, or combined experience (where each animal in the interaction was, itself, an observer and demonstrator). Exposures occurred 4 times, once every 48 hours. On P37, the reflexive behavioral response to EtOH odor was tested, using whole-body plethysmography. The odor-mediated responses of adolescent EtOH observers, demonstrators, and combined exposure animals all significantly differed from controls. Compared to controls, however, the magnitude of the behavioral effect was greatest in the combined exposure animals. Moreover, combined exposure as both an EtOH observer and demonstrator significantly differed from either form of individual EtOH experience. EtOH's component chemosensory qualities are known to be central contributors to its acceptance and increases in the acceptability of EtOH's odor, resulting from a social transmission experience, are predictive of enhanced EtOH avidity in adolescence. Our findings demonstrate that combined exposure as an observer and demonstrator, within a socially relevant framework, may

    We report a rare case of serious voluntary intoxication by laboratory thallium monobromate combined with alcohol intake by a 24-years old man. The diagnosis of thallium intoxication was based on history, nonspecific but typical clinical symptoms including gastrointestinal complaints, painful polyneuropathy, alopecia, and confirmed by the finding of increased thallium concentration in the urine. The treatment, performed at the due time, consisted of decontamination of the stomach by irrigation, administration of active charcoal and Prussian blue, correction of water and mineral dysbalance, symptomatic treatment, and led to complete recovery.

    Full Text Available HIV-1 acute infection, recent infection and transmitted drug resistance screening was integrated into voluntary HIV counseling and testing (VCT services to enhance the existing surveillance program in San Francisco. This study describes newly-diagnosed HIV cases and characterizes correlates associated with infection.A consecutive sample of persons presenting for HIV VCT at the municipal sexually transmitted infections (STI clinic from 2004 to 2006 (N = 9,868 were evaluated by standard enzyme-linked immunoassays (EIA. HIV antibody-positive specimens were characterized as recent infections using a less-sensitive EIA. HIV-RNA pooled testing was performed on HIV antibody-negative specimens to identify acute infections. HIV antibody-positive and acute infection specimens were evaluated for drug resistance by sequence analysis. Multivariable logistic regression was performed to evaluate associations. The 380 newly-diagnosed HIV cases included 29 acute infections, 128 recent infections, and 47 drug-resistant cases, with no significant increases or decreases in prevalence over the three years studied. HIV-1 transmitted drug resistance prevalence was 11.0% in 2004, 13.4% in 2005 and 14.9% in 2006 (p = 0.36. Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTI was the most common pattern detected, present in 28 cases of resistance (59.6%. Among MSM, recent infection was associated with amphetamine use (AOR = 2.67; p<0.001, unprotected anal intercourse (AOR = 2.27; p<0.001, sex with a known HIV-infected partner (AOR = 1.64; p = 0.02, and history of gonorrhea (AOR = 1.62; p = 0.03.New HIV diagnoses, recent infections, acute infections and transmitted drug resistance prevalence remained stable between 2004 and 2006. Resistance to NNRTI comprised more than half of the drug-resistant cases, a worrisome finding given its role as the backbone of first-line antiretroviral therapy in San Francisco as well as worldwide.

    Drug abuse is associated with a variety of neurological complications. The use of certain recreational drugs shows a marked temporal association with the onset of both haemorrhagic and ischaemic strokes, the majority of which develop within minutes to 1 h after the administration of the index drug. Delayed onset of stroke has also been observed. Acute, severe elevation of blood pressure, cardiac dysrhythmias, cerebral vasospasm, vasculitis, embolization due to infective endocarditis or dilated cardiomyopathy, embolization due to foreign material injected with the diluents under non-sterile conditions and 'street drug' contaminants with cardiovascular effects have been suggested as possible underlying mechanisms. Rupture of aneurysms and arteriovenous malformations have been detected in up to half of the patients with haemorrhagic stroke due to cocaine abuse. The less common findings reported have included a mycotic cerebrovascular aneurysm in a patient with infective endocarditis and haemorrhagic stroke. In addition to stroke, cocaine seems to provoke vascular headache. Seizures precipitated by recreational drug abuse are usually caused by acute intoxication in contrast to the withdrawal seizures encountered in subjects with alcohol abuse. Movement disorders and cerebral atrophy correlating with the duration of abuse have been described. Snorting of organic solvents may cause encephalopathy. Cases of spongiform leukoencephalopathy in heroin addicts have also been reported. Peripheral neuropathy is occasionally precipitated by drug poisoning after intravenous administration. Impurities of the drug, risky administration techniques, and the use of mixtures of various drugs, frequently with simultaneous alcohol drinking, should be taken into account when assessing the background of the adverse event as well as the overall lifestyle of the addicted subjects.

    2008-11-01

    For the first time since the year 2000 the number of death due to substance abuse of illegal drugs has increased in Germany in 2007 (+8 % compared to 2006). Emergency situations due to drug abuse are frequent, particular in big cities. They may be, however, difficult to diagnose and/or treat for an emergency physician on scene because of a lack of diagnostic tools, the local and personal surroundings, and the unknown number and nature of drugs. Many drug intoxications must be considered suicidal. On the other hand, drug intoxications may mask (other) life-threatening conditions. Emergency situations due to withdrawal offer the possibility to motivate patients to take advantage of specialist-guided abstinence programs.

    Full Text Available The present project was carried out to study the effects of acute and chronic mercury intoxication in Grass carp (Ctenopharyngodon idella. For acute phase experiment, 48 fish were divided into four equal groups (A, B, C and D. Groups B, C and D were given HgCl2 at sublethal dose as 0.4, 0.5 and 0.6 mg/L, respectively, while group A acted as control. Skin, gills and kidneys were isolated from the fish after 48 and 96 hours for pathological studies. For chronic phase, 72 fish were divided into five groups (E, F, G, H and I, containing 12 fish each except group E which contained 24 fish. Groups F, G, H and I were given HgCl2 at sublethal dose of 0.3 mg/L for 4, 8, 12 and 16 days, respectively, while group E acted as control. Skin, gills and kidneys were isolated from each group (F, G, H and I after 4, 8, 12 and 16 days respectively for pathological studies. During chronic phase in the treatment groups normal histology of epidermis was disturbed with increased number of immature cells. Overall, skin layers were atrophied and withered. Histopathology of gills showed hyperplasia of epithelial cells of gill filaments, fusion of secondary lamellae giving a club shaped appearance of filaments and contraction and sloughing of respiratory epithelium in groups F, G, H and I. Histopathological examination of kidneys also showed a wide range of toxicity lesions and destruction in treatment groups (F, G, H and I. Disintegration and disorganization of cells of both renal and haemopoitic systems including dilatation of capillaries and thickening of basal lumen were observed. Mild to sever tubular epithelial degeneration, karyolysis, dilation and shrinkage of Bowman’s capsule and glomerulus were also observed. In chronic phase experiment, fish showed clinical signs including restlessness, difficult breathing, fin flickering and jerky movements. Suppressed growth rate was also observed in treatment groups (F, G, H and I. During acute phase, after 48 hours, these

    Full Text Available Introduction: The available legal regulations in Poland do not define the concentration thresholds enabling to differentiate between the states of “after-use” versus “under the influence” of a drug, as it is in the case of alcohol. The aim of the study was to analyse jurisdiction in cases regarding the evaluation of the effects of intoxicating agents and ethanol-like intoxicants and to identify ambiguities and gaps in the applicable regulations leading to problems in preparing expert opinions. Material and methods: The material included the opinions of experts in the field of toxicology and forensic medicine made by the Department of Forensic Medicine in Lublin in the years 2009–2011 and records obtained in the process of inquiry from the regional prosecutor’s offices and courts in 52 cases. Results : Amongst 52 cases in which the ordered toxicology examinations demonstrated the presence of intoxicating agents in drivers’ blood (tetrahydrocannabinols in 39 and amphetamine in 21 cases in 2 cases petty offence proceedings were instituted (Art. 87 of the Petty Offence Code although high concentrations of xenobiotics indicated the state of being “under the influence” of a narcotic drug (Art. 178a of the Penal Code. Three cases were discontinued despite expert opinions that the drivers were at least in the after-narcotic use state. In only 3 cases were witnesses asked to provide testimony about the circumstances of the driver’s conduct. Conclusions : The analysis has demonstrated that judicial bodies expect forensic expertise based exclusively on toxicological examination results; when expert findings are inconclusive, they only administer litigations opportunistically applying the principle of the presumption of innocence understood literally. Considering the above, threshold values of “use” and “influence” of the most commonly detected drugs should be urgently determined.

    Increasing rates of opioid abuse, particularly fentanyl, may lead to more presentations of unusual effects of opioid toxicity. Diffuse alveolar hemorrhage is a rare complication of fentanyl overdose. A 45-year-old male presented in hypoxic respiratory failure secondary to diffuse alveolar hemorrhage requiring intubation. Comprehensive drug screening detected fentanyl without exposure to cocaine. Further history upon the patient's recovery revealed exposure to snorted fentanyl powder immediately prior to presentation. Diffuse alveolar hemorrhage is a potential, though rare, presentation of opioid intoxication. Recognition of less common complications of opioid abuse such as diffuse alveolar hemorrhage is important in proper management of overdoses.

    Our previous findings revealed that increased oxidative stress, apoptosis and necrosis were implicated in acute fluoride (F - ) induced cardiac dysfunction apart from hypocalcemia and hyperkalemia. Cardiac intermediate filaments (desmin and vimentin) and cytoskeleton linker molecule vinculin plays an imperative role in maintaining the architecture of cardiac cytoskeleton. In addition, AMPK is a stress activated kinase that regulates the energy homeostasis during stressed state. The present study was aimed to examine the role of cytoskeletal proteins and AMPK signaling molecules in acute F - induced cardiotoxicity in rats. In order to study this, male Wistar rats were treated with single oral doses of 45 and 90mg/kgF - for 24h. Acute F - intoxicated rats showed declined cytoskeletal protein expression of desmin, vimentin and vinculin in a dose dependent manner compared to control. A significant increase in phosphorylation of AMPKα (Thr172), AMPKß1 (Ser108) and Acetyl-coA carboxylase (ACC) (Ser79) in the myocardium and associated ATP deprivation were found in acute F - intoxicated rats. Further, ultra-structural studies confirmed myofibril lysis with interruption of Z lines, dilated sarcoplasmic reticulum and damaged mitochondrion were observed in both the groups of F - intoxicated rats. Taken together, these findings reveal that acute F - exposure causes sudden heart failure by altering the expression of cytoskeletal proteins and AMPK signaling molecules.

    Full Text Available Acute renal failure is a life threatening condition. Nonsteroidal antiinflammatory drugs (NSAIDs and cephalosporins are widely used postoperative drugs. NSAID-induced acute renal failure has been reported in the past. In this case, drug interaction and decompensated state of the patient precipitate the condition. NSAIDs inhibit prostaglandins synthesis and thus aggravate ischemia to the kidney that is already facing volume crisis due to surgery. Due to renal dysfunction, plasma ceftriaxone level increases due to decrease clearance and it also acts as nephrotoxic by unknown mechanism. On the other hand, ceftriaxone on its interaction with diclofenac for renal tubular clearance also increases the level of diclofenac and thus further aggravate the ischemia. It is a reversible condition with excluding diclofenac from the treatment regimen and giving adequate hydration to the patient. This highlights the importance of hydration and knowledge of drugs interactions in a postsurgical patient.

    There is no specific toxicological screening of clinical laboratory parameters in clinical toxicology when it comes to acute exogenous poisoning. To determine routine clinical laboratory parameters and indicators for assessment of vital functions in patients with acute intoxications. One hundred and fifty-three patients were included in the present study. They were hospitalized in the Department of Clinical Toxicology at St. George University Hospital, Plovdiv for cerebral toxicity inducing medication (n = 45), alcohol (n = 40), heroin abuse (n = 33). The controls were 35. The laboratory tests were conducted in compliance with the standards of the clinical laboratory. We used the following statistical analyses: analysis of variance (the ucriterion of normal distribution, the Student's t-test, dispersion analysis based on ANOVA) and non-parametric analysis. Based on the routine hematological parameters with statistically significant changes in three groups of poisoning are: red blood cells, hematocrit, hemoglobin (except alcohol intoxication) and leukocytes. We found statistically significant changes in serum total protein, sodium and bilirubin. The highest statistical significance is the increased activity of AST and ALT. We present a model for selection of clinical laboratory tests for severe acute poisoning with modern equipment under standardized conditions. The results of the study suggest that the clinical laboratory constellation we used can be used as a mandatory element in the diagnosis of moderate and severe intoxication with the mentioned toxic substances.

    The effects of ingesting ethanol have been shown to be somewhat variable in humans. To date, there appear to be but few universals. Yet, the question often arises: is it possible to determine if a person is intoxicated by observing them in some manner? A closely related question is: can speech be used for this purpose and, if so, can the degree of intoxication be determined? One of the many issues associated with these questions involves the relationships between a person's paralinguistic characteristics and the presence and level of inebriation. To this end, young, healthy speakers of both sexes were carefully selected and sorted into roughly equal groups of light, moderate, and heavy drinkers. They were asked to produce four types of utterances during a learning phase, when sober and at four strictly controlled levels of intoxication (three ascending and one descending). The primary motor speech measures employed were speaking fundamental frequency, speech intensity, speaking rate and nonfluencies. Several statistically significant changes were found for increasing intoxication; the primary ones included rises in F0, in task duration and for nonfluencies. Minor gender differences were found but they lacked statistical significance. So did the small differences among the drinking category subgroups and the subject groupings related to levels of perceived intoxication. Finally, although it may be concluded that certain changes in speech suprasegmentals will occur as a function of increasing intoxication, these patterns cannot be viewed as universal since a few subjects (about 20%) exhibited no (or negative) changes.

    All drug-associated deaths from 1989 to 2000 were analysed at the Institute of Forensic Medicine in Cologne. Information concerning sex, gender, drug consumption, time, place and circumstances of death were analysed. A number of 605 cases were recorded; in 518 cases a toxicological analysis was possible and in 171 an autopsy was performed. When it was possible to determine the cause of death form the information available, acute drug intoxication was recorded in 65%. Heroin head the list of identified substances. Sixty-three percent of the specimens showed a combination of several substances, especially a combination of morphine, benzodiazepines, other medications and alcohol. In comparison with other studies the percentage of methadone-positive specimens is low, even though the proportion of specimens positive for methadone increased from 1989 to 2000. This analysis is discussed using background information concerning the management of substitution therapy and the available literature.

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. © 2014 Pharmacotherapy Publications, Inc.

    Full Text Available Many patients are admitted to the intensive care unit (ICU for acute intoxication, serious complication of overdose, or withdrawal symptoms of illicit drugs. An acute withdrawal of drugs with addiction potential is associated with a sympathetic overactivity leading to marked psychomimetic disturbances. Acute intoxication or withdrawal of such drugs is often associated with life-threatening complications which require ICU admission and necessitate prolonged sedative analgesic medications, weaning from which is often complicated by withdrawal and other psychomimetic symptoms. Dexmedetomidine, an alpha-2 (α2 agonist, has been used successfully to facilitate withdrawal and detoxification of various drugs and also to control delirium in ICU patients. Herein, we report a case of a chronic opioid abuse (heroin patient admitted with acute overdose complications leading to a prolonged ICU course requiring sedative-analgesic medication; the drug withdrawal-related symptoms further complicated the weaning process. Dexmedetomidine infusion was successfully used as a sedative-analgesic to control the withdrawal-related psychomimetic symptoms and to facilitate smooth detoxification and weaning from opioid and other sedatives.

    A descriptive retrospective study of acute intoxication cases registered at the Complexo Hospitalario de Pontevedra (CHOP) between January 2005 and December 2008 was performed to find out the number and types of poisoning cases treated, their distribution according to patient's sex and age, chronology, type of toxic agents involved, intentionality, history, symptoms, clinical development, treatment and toxicological analysis used for diagnosis. Data were recorded using Clinica and IANUS software and consulting all paper records of patients with symptoms of poisoning. Data from a total of 1893 patients with a mean age of 35.6 ± 17.6 years (66% men) were included. Highest rates of poisoning were recorded on Saturdays and Sundays during the summer months (June, July and August). Drugs of abuse were the most common toxic agents (70.4%), ethyl alcohol accounting for 61% of these cases, which often involved males and with people with high degrees of dependency. In second place was poisoning resulting from the abuse of medical drugs, more commonly associated with females, and involving benzodiazepines in 73.2% of cases. The majority of these intoxications were intentional, and suicide attempts accounted for 18.8%. The problems most commonly resulting from the poisoning were neurological, and mortality rate was just 0.2%.

    Full Text Available In February 2012, 100% mortality was reported in a herd with 79 local sheep that were kept around of Abhar, Northwest of Iran. The ration for adult sheep was daily mixed (40 kg straw, 25 kg wheat and 2 kg Vit-C premix and accidentally 1 500 g of salinomycin (Salinomycin 12% Premix; Aras Bazar Laboratories, Iran had been added to the ration (22388 mg/kg = 22388 ppm and overnight was fed to herd. At the morning, 78 sheep were founded dead and one of them showed convulsive seizures. Postmortem examination revealed pulmonary congestion and edema, hemorrhages in abomasum, large pale kidney and white streak lines in myocardium. Main histopathologic lesions were extensive subepicardial and intercardiomyofibers hemorrhages, extensive cardiomyolysis and myocarditis in heart, severe hyperemia and extensive acute tubular necrosis (ATN in kidneys and focal necrosis and retention of bile cholangitis in the liver. In this study, on the basis of the history, observation of the ionophore remnant in the ration, clinical signs, gross and histopathological findings, acute salinomycin intoxication is definitely diagnosed.

    Full Text Available Cholinesterase activity in blood of laboratory rats was monitored. Rats were intoxicated with paraoxon at dosis of 0 – 65 – 125 – 170 – 250 – 500 nmol. The 250 nmol dose was found to be the LD50. An electrochemical sensor was found useful to provide information about cholinesterase activity. The decrease of cholinesterase activity was correlated to intoxication symptoms and mortality level. It was found that the symptoms of intoxication are not observed while at least 50% of cholinesterase activity in blood remains. The minimal cholinesterase activity essential to survival is around 10%, when compared with the initial state. No changes in levels of low moleculary weight antioxidants were observed.

    2014-04-01

    Full Text Available Alcohol intoxication and ischemic injury of skeletal muscles often accompany each other. It is shown that patients hospitalized with chronic alcoholism develop muscle fatigue. Skeletal muscle dysfunction in alcohol-dependent patients is caused by ethanol-associated myofibrillar atrophy and metabolic disbalance, while compression-ischemic lesions result from unconsciousness of the patient, in case of taking the critical alcohol dose. Therefore, the aim of this study is to discover typical m. gastrocnemius (cap. med. tetanic kinetics changes in alcohol intoxicated rats with experimentally induced vascular ischemia of hindlimb muscles under conditions of low-frequency progressive muscle fatigue. Experiments were carried out on 10 young male Wistar rats (149.5 ± 5.8 g kept under standard vivarium conditions and diet. The investigation was conducted in two phases: chronic (30 days and acute (3 hours experiment. All surgical procedures were carried out aseptically under general anesthesia. Ishemic m. gastrocnemius (cap. med. tetanic kinetic changes and force productivity in alcohol intoxicated rats were investigated in the isometric mode, with direct electrical stimulation. The fatigue of m. gastrocnemius (cap. med. was evaluated by three characteristic criteria: the first sag effect, the secondary force rise, the second sag effect. There have been 10 similar experiments: 5 series in each study group with 10 tetanic runs in each series. The highest amplitude of the native m. gastrocnemius (cap. med. tetanus relative to isoline was taken as 100% force response. The same pattern of m. gastrocnemius (cap. med. low-frequency fatigue development was found in both rat groups under study. It is evidenced by the absence of substantial m. gastrocnemius (cap. med. tetanus kinetics differences in alcohol intoxicated rats, compared with non-alcohol intoxicated rats during fatigue test. However, the appreciable m. gastrocnemius (cap. med. tetanic force reduction

    Full Text Available Drug-induced hepatotoxicity most commonly manifests as an acute hepatitis syndrome and remains the leading cause of drug-induced death/mortality and the primary reason for withdrawal of drugs from the pharmaceutical market. We report a case of acute liver injury in a 12-year-old Hispanic boy, who received a series of five antibiotics (amoxicillin, ceftriaxone, vancomycin, ampicillin/sulbactam, and clindamycin for cervical lymphadenitis/retropharyngeal cellulitis. Histopathology of the liver biopsy specimen revealed acute cholestatic hepatitis. All known causes of acute liver injury were appropriately excluded and (only drug-induced liver injury was left as a cause of his cholestasis. Liver-specific causality assessment scales such as Council for the International Organization of Medical Sciences/Roussel Uclaf Causality Assessment Method scoring system (CIOMS/RUCAM, Maria and Victorino scale, and Digestive Disease Week-Japan were applied to seek the most likely offending drug. Although clindamycin is the most likely cause by clinical diagnosis, none of causality assessment scales aid in the diagnosis.

    Lead is an environmental toxin and its effects are principally manifested in the brain. Glial and neuronal changes have been described during development following chronic or acute lead intoxication, however, little is known about the effects of chronic lead intoxication in adults. In this study we evaluated immunohistochemically the glial and dopaminergic systems in adult male Wistar rats. 0.5% (v/v) lead acetate in drinking water was administrated chronically over a 3-month period. Hypertrophic immunoreactive astrocytes were observed in the frontal cortex and other brain structures of the treated animals. Analysis of the astroglial features showed increased number of astrocyte cell bodies and processes in treated rats, an increase confirmed by Western blot. Particular distribution of glial fibrillary acidic protein immunoreactivity was observed within the blood vessel walls in which dense immunoreactive glial processes emanate from astrocytes. Glial changes in the frontal cortex were concomitant with reduced tyrosine hydroxylase immunoreactive neuronal processes, which seem to occur as a consequence of significantly reduced dopaminergic neurons within the nucleus of origin in the substantia nigra. These glial and neuronal changes following lead intoxication may affect animal behavior as evidenced by reduced locomotor activity in an open field test. These findings demonstrate that chronic lead exposure induces astroglial changes, which may compromise neuronal function and consequently animal behavior. Copyright © 2010 Elsevier GmbH.

    2016-04-01

    Full Text Available The Price of Eternal Vigilance: Women and Intoxication by Michelle McClellan. The author argues that the “cultural meaning of intoxication is shaped profoundly by the reality that we seem to only hear about it from women who have given it up.” This is a problem when it obscures the reasons why women seek out alcohol. Resisting the seemingly inevitable trajectory of addiction and recovery narratives, McClellan introduces the concepts of “dry” and “wet” feminism to draw attention to both the cultural expectations women face and the ways that intoxication might serve as a form of resistance. By refusing to see intoxication as a sort of false consciousness from which women must awake, McClellan demonstrates that it reflects female ambivalence about mothering, sexuality, and pleasure itself.

    Experimental analogue methods were used to study how acute alcohol intoxication in parents influences their perceptions of and reactions to child behaviors, as well as their strategies for management of those behaviors. All participating parents had a grade school-aged son, but in half the cases this target child had a diagnosed externalizing disorder, whereas for the remaining half neither the target son nor any other offspring of the parents evidenced any psychopathology. Equal numbers of married fathers, married mothers, and single mothers from each of these groups received either alcoholic or nonalcoholic beverages prior to videotaped interactions with male child confederates who, depending on condition, enacted behaviors characteristic of either normal boys or boys with attention deficit hyperactivity/conduct/oppositional defiant disorders (ADHD/CD/ODD). Results indicated that intoxicated parents rated their ADHD/CD/ODD child partners as less deviant than did sober parents. Alcohol intoxication caused all participant groups to exhibit less attention and productive work and more commands, indulgences, and off-task talk in the interactions. Implications for better understanding of the role of psychosocial factors in the correlation between adult drinking problems and childhood behavior disorders are discussed.

    HIV infection and drugs of abuse such as methamphetamine (METH), cocaine, and alcohol use have been identified as risk factors for triggering inflammation. Acute phase proteins such as C-reactive protein (CRP) and serum amyloid A (SAA) are the biomarkers of inflammation. Hence, the interactive effect of drugs of abuse with acute phase proteins in HIV-positive subjects was investigated. Plasma samples were utilized from 75 subjects with METH use, cocaine use, alcohol use, and HIV-positive alone and HIV-positive METH, cocaine, and alcohol users, and age-matched control subjects. The plasma CRP and SAA levels were measured by ELISA and western blot respectively and the CD4 counts were also measured. Observed results indicated that the CRP and SAA levels in HIV-positive subjects who are METH, cocaine and alcohol users were significantly higher when compared with either drugs of abuse or HIV-positive alone. The CD4 counts were also dramatically reduced in HIV-positive with drugs of abuse subjects compared with only HIV-positive subjects. These results suggest that, in HIV-positive subjects, drugs of abuse increase the levels of CRP and SAA, which may impact on the HIV infection and disease progression.

    Psychomotor stimulants are frequently used by humans to intensify the subjective experience of different types of social interactions. Since psychomotor stimulants enhance metabolism and increase body temperatures, their use under conditions of physiological activation and in warm humid environments could result in pathological hyperthermia, a life-threatening symptom of acute drug intoxication. Here, we will describe the brain hyperthermic effects of MDMA, MDPV, and methylone, three structurally related recreational drugs commonly used by young adults during raves and other forms of social gatherings. After a short introduction on brain temperature and basic mechanisms underlying its physiological fluctuations, we will consider how MDMA, MDPV, and methylone affect brain and body temperatures in awake freely moving rats. Here, we will discuss the role of drug-induced heat production in the brain due to metabolic brain activation and diminished heat dissipation due to peripheral vasoconstriction as two primary contributors to the hyperthermic effects of these drugs. Then, we will consider how the hyperthermic effects of these drugs are modulated under conditions that model human drug use (social interaction and warm ambient temperature). Since social interaction results in brain and body heat production, coupled with skin vasoconstriction that impairs heat loss to the external environment, these physiological changes interact with drug-induced changes in heat production and loss, resulting in distinct changes in the hyperthermic effects of each tested drug. Finally, we present our recent data, in which we compared the efficacy of different pharmacological strategies for reversing MDMA-induced hyperthermia in both the brain and body. Specifically, we demonstrate increased efficacy of the centrally acting atypical neuroleptic compound clozapine over the peripherally acting vasodilator drug, carvedilol. These data could be important for understanding the potential

    Full Text Available Acute pancreatitis is a sudden inflammation of pancreas where its enzymes autodigest the gland. Two main causes of acute pancreatitis are alcoholism and billiar calculosis. Treatment consists of preventing dehydration, analgesia, decrease of pancreatic exocrine function, enteral nutritional support , respiratory and renal function support and surgery. The patient presents with abdominal pain that lasts for few days and is followed by vomiting. Laboratory tests first revealed abnormal values of blood count and pancreas enzymes (leucocytes -19,7 x 109/L, hematocrit - 0,32, amylase - 52569 IU/L, lypase - 4750 IU/L, CRP - 152 IU/L, albumins - 25 g/L, followed by abnormal values of liver enzymes (AST - 80 IU/L, ALT - 127 IU/L, GGT - 362 IU/L. Further diagnostic procedures showed billiary calculosis, pleural effusion and acute pancreatitis with ascites. No surgery was performed, due to the lack of infect ion and the signs of the patient going into recovery. It was observed that not all diagnostic procedures that exist in the protocol of treatment, such as ERCP or biopsy of pancreatic t issue with microbiological investigation, were performed. Considering the rules of rat ional drug therapy, as well as the protocols that are to be applied in Clinical center 'Kragujevac' in Kragujevac, it was observed that some drugs (antibiotics and albumin were not used in a proper manner, i.e. in compliance with the protocol, which increased the cost of the treatment without improving the patient health or shortening the hospital stay.

    The toxic effect of organophosphorus compounds (OPC) is based on inhibition of acetylcholinesterase (AChE), enzyme which plays an important physiological role in the cholinergic nervous system. The drug therapy on intoxication with OPC included mainly combination of cholinesterase reactivators and cholinolytics. There is no single AChE reactivator having the ability to sufficiently reactivate inhibited enzyme due to the high variability of chemical structure of the inhibitors. The classic oximes have antidote effect against intoxication with sarin, Vx and tabun, but are not effective against soman. HI-6 (Bulgarian ampoule form T oxidin ) has an effect against sarin, soman and Vx, and to a lesser degree against tabun. In order to improve the treatment of poisoning with highly toxic OPC, in ours laboratory we synthesized a variety of mono- and dioximes. We use different numbers of pyridinium or heterocyclic rings, different length and shape of the connecting chain between pyridinium or pyridinium-heterocyclic rings; different number and position of the oxime groups at the pyridinium rings and others. The investigations of some authors and our research showed that the compounds which present a combination between HI-6 and TMB-4 have a better antidote activity against tabun intoxications. The important finding of this study is that we synthesized complex compounds, reactivators of cholinesterase activity (including HI-6) with AMP / ATP and polycarboxilats, which have prolonged action in organism compared with original oximes. Pharmacokinetic studies showed that they are eliminated more slowly. The antidotal efficacy of these compounds after soman poisoning in rats was similar like that of the original oximes. The same tendency showed and the other pharmacological (blood pressure, EKG, breathing, neuromuscular transmission), and biochemical (ChE) investigations. (author)

    To develop the Intoxicated Personality Scale (IPS). Data were collected from 436 college students via an online survey. Through an iterative measurement development process, the resulting IPS was created. The 5 subscales (Good Time, Risky Choices, Risky Sex, Emotional, and Introvert) of the IPS positively related to alcohol consumption, alcohol problems, drinking motives, alcohol expectancies, and personality. The results suggest that the Intoxicated Personality Scale may be a useful tool for predicting problematic alcohol consumption, alcohol expectancies, and drinking motives.

    Cannabis intoxication in toddlers is rare and mostly accidental. Our objectives were to focus on the characteristics and management of children under the age of 6 years who were admitted to our emergency department with cannabis poisoning reported as accidental by parents, and to point out the need to consider accidental cannabis ingestions as an indicator of neglect. The medical records of children hospitalized for cannabis poisoning in a pediatric emergency department from January 2007 to November 2012 were retrospectively evaluated. Data collected included age, sex, drug ingested, source of drug, intentional versus accidental ingestion, pediatric intensive care unit or hospital admission, treatment and length of hospital stay, toxicology results, and rate of child protectives services referral. Twelve toddlers (4 boys and 8 girls; mean age, 16.6 months) were included. All had ingested cannabis. Their parents reported the ingestion. Seven children experienced drowsiness or hypotonia. Three children were given activated charcoal. Blood screening for cannabinoids, performed in 2 cases, was negative in both, and urine samples were positive in 7 children (70%). All children had favorable outcomes after being hospitalized from 2 to 48 hours. Nine children were referred to social services for further assessment before discharge. Cannabis intoxication in children should be reported to child protection services with the aim of prevention, to detect situations of neglect and at-risk families. Legal action against the parents may be considered. Accidental intoxication and caring parents should be no exception to this rule.

    Many substances can affect the central nervous system, and may cause patients to become critically ill. Acute central neurotoxicologic syndromes associated with drugs of abuse are usually caused by an overdose of sedative-hypnotic agents (including alcohol) or opioids, withdrawal from sedative-hypnotic agents, or an overdose of anticholinergic or sympathomimetic agents. Clinical findings are often syndromic, making physical examination the most important diagnostic tool in the approach to the patient with an unknown ingestion. Treatment focusses on supportive care as the most important intervention for all such patients, augmented by antidotal therapy when appropriate. © 2017 Elsevier B.V. All rights reserved.

  1. Recreational drug discovery: natural products as lead structures for the synthesis of smart drugs.

    Appendino, Giovanni; Minassi, Alberto; Taglialatela-Scafati, Orazio

    2014-07-01

    Covering: up to December 2013. Over the past decade, there has been a growing transition in recreational drugs from natural materials (marijuana, hashish, opium), natural products (morphine, cocaine), or their simple derivatives (heroin), to synthetic agents more potent than their natural prototypes, which are sometimes less harmful in the short term, or that combine properties from different classes of recreational prototypes. These agents have been named smart drugs, and have become popular both for personal consumption and for collective intoxication at rave parties. The reasons for this transition are varied, but are mainly regulatory and commercial. New analogues of known illegal intoxicants are invisible to most forensic detection techniques, while the alleged natural status and the lack of avert acute toxicity make them appealing to a wide range of users. On the other hand, the advent of the internet has made possible the quick dispersal of information among users and the on-line purchase of these agents and/or the precursors for their synthesis. Unlike their natural products chemotypes (ephedrine, mescaline, cathinone, psilocybin, THC), most new drugs of abuse are largely unfamiliar to the organic chemistry community as well as to health care providers. To raise awareness of the growing plague of smart drugs we have surveyed, in a medicinal chemistry fashion, their development from natural products leads, their current methods of production, and the role that clandestine home laboratories and underground chemists have played in the surge of popularity of these drugs.

    Thiamine and benfotiamine are vitamin B1 and pro-vitamin B1 substances, respectively. Vitamin B1 plays an essential role in energy metabolism, and its deficiency leads to neurologic and cardiovascular pathologies, as seen in alcoholics. This study presents new data about the effects of thiamine hydrochloride or benfotiamine treatment given to rats with acute alcohol intoxication, on the distribution of thiamine and its phosphate esters in liver, plasma and erythrocytes. The treatments were effective in increasing thiamine levels in plasma, erythrocytes and liver cells. The benfotiamine-treated group had its total plasma thiamine increased by 100%. In erythrocytes, thiamine levels were 4- and 25-fold higher in the groups treated with thiamine and benfotiamine, respectively, compared with the untreated groups. Liver thiamine was increased by 60% in the treated groups compared with the untreated groups. Thus, we verified the high bioavailability especially of benfotiamine within 6h of ethanol administration. Copyright © 2013 Elsevier B.V. All rights reserved.

    2017-12-01

    The goal of this article was to provide an overview of the literature available on carbon dioxide intoxication. Articles were included based on their focus on medical or physiological effects of carbon dioxide. Studies related to decompression sickness were excluded. Mechanisms of carbon dioxide poising (both as an asphyxiant and as a toxicant) were described. Our review suggested that precautions are needed when handling dry ice or while working in confined spaces. Pre-hospital responders also need to pay attention for the possible diagnosis of CO 2 intoxication for their own safety. When confronted with a victim, he/she should be removed from the dangerous area as fast as possible and oxygen should be administered. Without adequate treatment, victims may show acute reduced cognitive performance, respiratory failure, and circulatory arrest. Therefore, carbon dioxide poisoning is a rare but not to miss diagnosis in the emergency department.

  4. Effects of experimental amitraz intoxication in cats

    2007-10-01

    Full Text Available This work studied the effects of experimental amitraz intoxication in cats. Sixteen cats were randomly divided equally into two groups: amitraz group - animals received 1.5% amitraz at 1mg/kg IV; and the control group - animals without amitraz. Physiological parameters from blood, cardiorespiratory system, and sedation indicators were quantified over time up to 360 minutes. Blood profile, urea, creatinine, alananine aminotransferase and aspartate aminotransferase were not affected by amitraz. Sedation, loss of reflexes, hypothermia, bradycardia, bradyarrhythmia, hypotension, bradypnea, mydriasis, besides transitory hyperglycemia, hypoinsulinemia and decrease of cortisol levels were observed in cats experimentally exposed to amitraz. The alpha2-adrenergic effects induced by amitraz intoxication in cats are very similar to the same effects reported in others species, contributing with more information about this type of intoxication to veterinary toxicology.

    In an attempt to discover new possibilities for advertising in uncluttered environments marketers have recently begun using ambient advertising in, for instance, bars and pubs. However, advertising in such licensed premises have to deal with the fact that many consumers are under the influence of alcohol while viewing the ad. This paper examines the effect of alcohol intoxication on attention to and memory for advertisements in two experiments. Study 1 used a forced exposure manipulation and revealed increased attention to logos under alcohol intoxication consistent with the psychopharmacological prediction that alcohol intoxication narrows attention to the more salient features in the visual environment. Study 2 used a voluntary exposure manipulation in which ads were embedded in a magazine. The experiment revealed that alcohol intoxication reduces voluntary attention to ads and leads to a significant reduction in memory for the viewed ads. In popular terms consuming one or two beers reduces brand recall from 40 to 36% while being heavily intoxicated further reduces brand recall to 17%.

    Full Text Available Drug reaction with eosinophilia and systemic symptoms (DRESS or drug-induced hypersensitivity is a severe adverse drug-induced reaction. Aromatic anticonvulsants, such as phenytoin, phenobarbital, and carbamazepine, and some drugs, can induce DRESS. Atypical crystalluria can be seen in patients treated with amoxycillin or some drugs and can cause acute renal failure. We describe a 66-year-old man who presented fever and rash and acute renal failure three days after starting amoxycillin. He was also using phenytoin because of cerebral metastatic lung cancer. Investigation revealed eosinophilia and atypical crystalluria. The diagnosis of DRESS syndrome was made, amoxicillin was stopped, and dose of phenytoin was reduced. No systemic corticosteroid therapy was prescribed. Symptoms began to resolve within three to four days. The aim of this paper is to highlight the importance of microscopic examination of urine in a case with acute renal failure and skin lesions to suspect DRESS syndrome.

    Background We aimed to characterize the content of leading YouTube videos related to alcohol intoxication and to examine factors associated with alcohol intoxication in videos that were assessed positively by viewers. Methods We systematically captured the 70 most relevant and popular videos on YouTube related to alcohol intoxication. We employed an iterative process to codebook development which resulted in 42 codes in 6 categories: video characteristics, character socio-demographics, alcohol depiction, degree of alcohol use, characteristics associated with alcohol, and consequences of alcohol. Results There were a total of 333,246,875 views for all videos combined. While 89% of videos involved males, only 49% involved females. The videos had a median of 1646 (IQR 300-22,969) “like” designations and 33 (IQR 14-1,261) “dislike” designations each. Liquor was most frequently represented, followed by beer and then wine/champagne. Nearly one-half (44%) of videos contained a brand reference. Humor was juxtaposed with alcohol use in 79% of videos, and motor vehicle use was present in 24%. There were significantly more likes per dislike, indicating more positive sentiment, when there was representation of liquor (29.1 vs. 11.4, p = .008), brand references (32.1 vs. 19.2, p = .04), and/or physical attractiveness (67.5 vs. 17.8, p < .001). Conclusions Internet videos depicting alcohol intoxication are heavily viewed. Nearly half of these videos involve a brand-name reference. While these videos commonly juxtapose alcohol intoxication with characteristics such as humor and attractiveness, they infrequently depict negative clinical outcomes. The popularity of this site may provide an opportunity for public health intervention. PMID:25703135

    Kupper, Jacqueline; Reichert, Cornelia

    2009-05-01

    Ingestions of plants rarely lead to life-threatening intoxications. Highly toxic plants, which can cause death, are monkshood (Aconitum sp.), yew (Taxus sp.) and autumn crocus (Colchicum autumnale). Lethal ingestions of monkshood and yew are usually suicides, intoxications with autumn crocus are mostly accidental ingestions of the leaves mistaken for wild garlic (Allium ursinum). Severe intoxications can occur with plants of the nightshade family like deadly nightshade (Atropa belladonna), angel's trumpet (Datura suaveolens) or jimsonweed (Datura stramonium). These plants are ingested for their psychoactive effects. Ingestion of plant material by children most often only causes minor symptoms or no symptoms at all, as children usually do not eat great quantities of the plants. They are especially attracted by the colorful berries. There are plants with mostly cardiovascular effects like monkshood, yew and Digitalis sp. Some of the most dangerous plants belong to this group. Plants of the nightshade family cause an anticholinergic syndrome. With golden chain (Laburnum anagyroides), castor bean (Ricinus communis) and raw beans (Phaseolus vulgaris) we see severe gastrointestinal effects. Autumn crocus contains a cell toxin, colchicine, which leads to multiorgan failure. Different plants are irritative or even caustic to the skin. Treatment is usually symptomatic. Activated charcoal is administered within one hour after ingestion (1 g/kg). Endoscopic removal of plant material can be considered with ingestions of great quantities of highly toxic plants. Administration of repeated doses of charcoal (1-2 g/h every 2-4 hours) may be effective in case of oleander poisoning. There exist only two antidotes: Anti-digoxin Fab fragments can be used with cardenolide glycoside-containing plants (Digitalis sp., Oleander). Physostigmine is the antidote for severe anticholinergic symptoms of the CNS. Antibodies against colchicine, having been developed in France, are not available at

  11. Drunk, but not blind: the effects of alcohol intoxication on change blindness.

    2013-03-01

    Alcohol use has long been assumed to alter cognition via attentional processes. To better understand the cognitive consequences of intoxication, the present study tested the effects of moderate intoxication (average BAC between .071 and .082) on attentional processing using complex working memory capacity (WMC) span tasks and a change blindness task. Intoxicated and sober participants were matched on baseline WMC performance, and intoxication significantly decreased performance on the complex span tasks. Surprisingly, intoxication improved performance on the change blindness task. The results are interpreted as evidence that intoxication decreases attentional control, causing either a shift towards more passive processing and/or a more diffuse attentional state. This may result in decreased performance on tasks where attentional control or focus are required, but may actually facilitate performance in some contexts. Copyright © 2013 Elsevier Inc.

    1982-01-01

    The renal function was assessed of 12 patients with professional lead intoxication by radioisotope examination methods. In six patients changes on the radionephrographic curve were observed, showing flattening and shift of the peak of the curve, and prolongation of the secretory and excretory phases. The phase scintiscan displayed a slowed down uptake of the radioactive substance and pathological persistance of activity in the kidneys. The impairment of renal functions proved to be reversible. The authors consider rad+oisotope examinations to be an appropriate approach permitting evaluation of renal functions during lead intoxication, as well as helping to assess the deployment of persons who had suffered from intoxication, to workplaces where there is danger of exposure to lead.

  13. EFFECT OF ACUTE RENAL FAILURE ON KIDNEY AMIDINOTRANSFERASE ACTIVITY

    Directory of Open Access Journals (Sweden)

    Jelenka Nikolic

    2004-04-01

    Full Text Available L-Arginine-:glycine amidinotransferase (EC 2.1.4.1 catalyzes the transfer of an amidino group from arginine to glycine to form guanidinoacetate, precursor in creatine synthesis. The kidneys are major site of the creatine synthesis and primary target organs for mercury toxicity. In evaluation of molecular mechanisms of mercury chloride intoxication relating to creatine metabolism we have investigated the enzyme activity in kidney tissue after mercury chloride administration. Acute renal failure was induced by i.p administration of mercury chloride in a dose of 3 mg/kg to male Spraque Dawley rats weighing about 200 g. The results of our study indicate an acute renal failure 24 hours after mercury chloride administration. Urea and creatinine levels in blood plasma were significantly elevated compared to control group (p<0.001. Amidinotransferase activity in kidney tissue was depressed, while, in plasma of intoxicated rats activity of enzyme was increased (p<0.001. The obtained results indicate that mercury chloride has strong nephrotoxic effect. Depressed amidinotransferase activity and decreased production of guanidinoacetate, initial product in creatine synthesis, may be implicated in neurotoxicity, cardiotoxicity and muscle damage in mercury intoxication, because creatine and its phosphorylated form creatine phosphate play an important role in the energy metabolism.

  14. Non-medical use of prescription drugs among illicit drug users: A case study on an online drug forum.

    2017-01-01

    The non-medical use of prescription drugs is a growing phenomenon associated with increasing health-related harms. However, little is known about the drivers of this process among illicit drug users. Our aim is to show how the qualities of pharmaceutical drugs, pharmaceutical related knowledge, online communities sharing this knowledge and medical professionals mediate and transform the consumption behaviour related to pharmaceutical drugs. The data consist of discussion threads from an online drug use forum. Using actor network theory (ANT), we analysed translations that mediate the online user community's relationship with pharmaceutical drugs. Differences in experienced drug effects are explained both as a process of 'learning' and as differences in brain chemistry at the receptor level. Both science- and experience-based information are shared on best practices to optimise use, avoid adverse health effects and maximise the experience of intoxication. The expanded context of doctors' practices places stress on the medical framework for drug use. Our analysis shows how the non-medical use of psychoactive pharmaceuticals relates to joint, medicalised ideas of bodies as sites of medical experimentation, as well as to the collective process of constructing 'pharmaceutical competences' in user networks. Understandings of intoxication have increasingly been permeated with the pharmacological and scientific logic of knowledge. The forum works as a platform for harm reduction inspired exchange of knowledge. However, the user community's knowledge sharing practices can generate a shared perception of a sufficient or even superior drug use experience and knowledge. This may lead to overdoses and other risky behaviour, and thereby contribute to increased harms related to non-medical use of prescription drugs. Copyright © 2016 Elsevier B.V. All rights reserved.

    2009-07-01

    Some intoxications are more specifically linked to the Aquitaine region than to other regions of France, due to environmental circumstances (fauna, flora, climate) or traditional activities (gastronomy). Three types of intoxications are particular in this area. Pine processionary caterpillar envenomations (Thaumetopoea pityocampa), a Southern Europe pinewood parasite, are frequently encountered in the Landes' forest. They are responsible of ocular and/or skin lesions with urticaria or contact dermatitis, seldom associated with immediate IgE hypersensitivity. According to the south Atlantic coastal region geology and the marine streams, venomous marine animals are mainly located in Charente-Maritime for jellyfish, in Gironde and in Landes for weeverfish and in Atlantic Pyrenees for sea anemone. Usually not dangerous, first-aid workers treat most cases of these envenomations. Some endemic mushrooms (Tricholoma auratum) which grow on the dunes of the Atlantic coastal region, are usually considered as very good comestibles, but were recently responsible for serious intoxications: T.auratum was responsible of several cases of rhabdomyolysis, without neurological involvement, nor renal or hepatic lesion. Three deaths were notified. Animal studies confirmed the responsibility of the mushrooms.

  20. Acute diarrhea in children

    Directory of Open Access Journals (Sweden)

    Radlović Nedeljko

    2015-01-01

    Full Text Available Acute diarrhea (AD is the most frequent gastroenterological disorder, and the main cause of dehydration in childhood. It is manifested by a sudden occurrence of three or more watery or loose stools per day lasting for seven to 10 days, 14 days at most. It mainly occurs in children until five years of age and particularly in neonates in the second half-year and children until the age of three years. Its primary causes are gastrointestinal infections, viral and bacterial, and more rarely alimentary intoxications and other factors. As dehydration and negative nutritive balance are the main complications of AD, it is clear that the compensation of lost body fluids and adequate diet form the basis of the child’s treatment. Other therapeutic measures, except antipyretics in high febrility, antiparasitic drugs for intestinal lambliasis, anti-amebiasis and probiotics are rarely necessary. This primarily regards uncritical use of antibiotics and intestinal antiseptics in the therapy of bacterial diarrhea. The use of antiemetics, antidiarrhetics and spasmolytics is unnecessary and potentially risky, so that it is not recommended for children with AD.

    2016-10-01

    The aim of this study was to evaluate possible beneficial effects of treatment with thiamine or benfotiamine in an animal model of acute ethanol intoxication. Thirty male Wistar rats were separated at random into three groups of 10 animals each: Ethanol (E), Ethanol treated with thiamine (T) and Ethanol treated with benfotiamine (BE). Rats were gavaged with single dose of ethanol (5g/kg, 40% v:v). After 30min of ethanol gavage the animals were treated with thiamine or benfotiamine. Six hours after first gavage, the animals were euthanized and blood and liver samples were collected for ethanol and oxidative stress biomarkers quantification. Serum ethanol levels were higher in animals treated with thiamine or benfotiamine while hepatic alcohol levels were higher in animals of the group treated with benfotiamine comparing to controls or thiamine treated groups. The lipid peroxidation biomarkers were diminished for the groups treated with thiamine or benfotiamine comparing to E animals. Concerning protein oxidative damage parameters, they were enhanced for animals treated with benfotiamine in relation to other groups. In conclusion, the treatment with thiamine or benfotiamine even 30min after the massive dose of ethanol has proven to be beneficial against liver damage. Improved results were obtained with benfotiamine in relation to oxidative damage from aqueous compartments. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available This article refers to the phenomenon of an increasing number of people abusing drugs in the 20th century. In addition to the natural types of narcotics there are many other semi-synthetic and fully synthetic substances made available to the market by chemical and pharmaceutical industries. The use of narcotics and psychoactive substances usually causes adverse and often irreversible health effects. In Department of Laboratory Diagnostics of the Institute of Occupational Medicine and Environmental Health in Sosnowiec tests for presence of drugs are among routinely conducted analyses. The presence of drugs has been revealed in 898 cases between the years 2004 and 2008. On top of the list of the most frequently detected narcotics were: amphetamine, cannabis, opiates, methamphetamine and cocaine. At the same time the most popular psychoactive substances are atropine, scopolamine and psilocybin. Additionally, the laboratory analyses indicated in many cases the presence of derivatives of benzodiazepines, trycyclic antidepressants and alcohol. Regional Centre of Acute Intoxication in Sosnowiec, Poland, hospitalized 78 patients due to overdose of drugs, narcotics or psychoactive substances as a result of experimenting with such substances. Half of the hospitalized cases patients have tried to commit suicide; one of the attempts has led to death. According to patients’ history their problems with reaching out for the use of psychoactive substances and narcotics were mainly caused by socio-psychological disorders.

    The information available on the incidence and the characteristics of patients with acute renal failure (ARF) related to drugs is scarce. To estimate the incidence of drug-related ARF in hospitalised patients and to compare their characteristics with those of patients with ARF due to other causes. We selected a prospective cohort of patients with ARF during hospital admission (July 2010-July 2011). Information on patients' demographics, medical antecedents, ARF risk factors, ARF severity according to the RIFLE classification and hospital drug administration was collected. We analysed the relationship of drugs with the ARF episodes using Spanish Pharmacovigilance System methods and algorithm. A total of 194 cases had an episode of hospital-acquired ARF. The median age of patients was 72 years [IQR 20]; 60% were men. The ARF incidence during hospitalization was 9.6 per 1,000 admissions. According to the RIFLE classification, a risk of kidney damage or kidney injury was present in 77.8% of cases. In 105 (54.1%) cases, ARF was drug-related; the drugs most frequently involved were diuretics, agents acting on the renin-angiotensin system, immunosuppressants, β-blocking agents, calcium channel blockers, contrast media and non-steroid anti-inflammatory drugs. Patients with drug-related ARF had more multi-morbidity, fewer ARF risk factors and lower mortality. Half of ARF episodes during hospitalisation were drug related. Patients with drug-related ARF had higher cardiovascular morbidity than those with ARF related to other causes, but they had a lower frequency of ARF risk factors and mortality.

    In an attempt to discover new possibilities for advertising in uncluttered environments marketers have recently begun using ambient advertising in, for instance, bars and pubs. However, advertising in such licensed premises have to deal with the fact that many consumers are under the influence of alcohol while viewing the ad. This paper examines the effect of alcohol intoxication on attention to and memory for advertisements in two experiments. Study 1 used a forced exposure manipulation and revealed increased attention to logos under alcohol intoxication consistent with the psychopharmacological prediction that alcohol intoxication narrows attention to the more salient features in the visual environment. Study 2 used a voluntary exposure manipulation in which ads were embedded in a magazine. The experiment revealed that alcohol intoxication reduces voluntary attention to ads and leads to a significant reduction in memory for the viewed ads. In popular terms consuming one or two beers reduces brand recall from 40 to 36% while being heavily intoxicated further reduces brand recall to 17%. PMID:24723899

    Accidental intoxications in children are frequent but most of them are without serious consequences. We describe herein the case of a young girl who drank 100 mg of a topical hair lotion with minoxidil. On arrival, she had no symptoms except flush on the face and ears. Four and half hours after ingestion, tachycardia appeared with a pulse above 170 beats per min with hypotension at 76/24 mmHg. The heart rate remained between 170 and 190 beats per min for 12 h and then lowered to between 140 and 160 beats per min. Thirty-six hours after ingestion, the heart beat was at 140 beats per min. Minoxidil is a strong vasodilator used first in the 1970s for severe hypertension. It produces hypotension by direct arteriolar vasodilatation. Only a few cases of minoxidil intoxication have been described in the literature, including only one pediatric case. This young boy had only tachycardia of 160 beats per min for 40 h. Most serious cases have been described in adults. They suffered long-lasting tachycardia, hypotension, and ECG changes. Most patients need a bolus of normal saline fluid and some with hemodynamic problems need vasoactive drugs such as dopamine and/or phenylephrine. All patients need to be under medical supervision for a long time because of the product's very long action. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    We aimed to characterize the content of leading YouTube videos related to alcohol intoxication and to examine factors associated with alcohol intoxication in videos that were assessed positively by viewers. We systematically captured the 70 most relevant and popular videos on YouTube related to alcohol intoxication. We employed an iterative process to codebook development which resulted in 42 codes in 6 categories: video characteristics, character socio demographics, alcohol depiction, degree of alcohol use, characteristics associated with alcohol, and consequences of alcohol. There were a total of 333,246,875 views for all videos combined. While 89% of videos involved males, only 49% involved females. The videos had a median of 1,646 (interquartile range [IQR] 300 to 22,969) "like" designations and 33 (IQR 14 to 1,261) "dislike" designations each. Liquor was most frequently represented, followed by beer and then wine/champagne. Nearly one-half (44%) of videos contained a brand reference. Humor was juxtaposed with alcohol use in 79% of videos, and motor vehicle use was present in 24%. There were significantly more likes per dislike, indicating more positive sentiment, when there was representation of liquor (29.1 vs. 11.4, p = 0.008), brand references (32.1 vs. 19.2, p = 0.04), and/or physical attractiveness (67.5 vs. 17.8, p < 0.001). Internet videos depicting alcohol intoxication are heavily viewed. Nearly, half of these videos involve a brand-name reference. While these videos commonly juxtapose alcohol intoxication with characteristics such as humor and attractiveness, they infrequently depict negative clinical outcomes. The popularity of this site may provide an opportunity for public health intervention. Copyright © 2015 by the Research Society on Alcoholism.

    Chemotherapeutic drug efflux via the P-glycoprotein (P-gp) transporter encoded by the MDR1/ABCB1 gene is a significant cause of drug resistance in numerous malignancies, including acute leukemias, especially in older patients with acute myeloid leukemia (AML). Therefore, the P-gp modulators that block P-gp-mediated drug efflux have been developed, and used in combination with standard chemotherapy. In this paper, the capacity of zosuquidar, a specific P-gp modulator, to reverse chemoresistance was examined in both leukemia cell lines and primary AML blasts. The transporter protein expressions were analyzed by flow cytometry using their specific antibodies. The protein functionalities were assessed by the uptake of their fluorescence substrates in presence or absence their specific modulators. The drug cytotoxicity was evaluated by MTT test. Zosuquidar completely or partially restored drug sensitivity in all P-gp-expressing leukemia cell lines tested and enhanced the cytotoxicity of anthracyclines (daunorubicin, idarubicin, mitoxantrone) and gemtuzumab ozogamicin (Mylotarg) in primary AML blasts with active P-gp. In addition, P-gp inhibition by zosuquidar was found to be more potent than cyclosporine A in cells with highly active P-gp. These in vitro studies suggest that zosuquidar may be an effective adjunct to cytotoxic chemotherapy for AML patients whose blasts express P-gp, especially for older patients

    To characterize the clinical and clinicopathologic effects and evaluate outcome associated with oleander toxicosis in New World camelids. Retrospective case series. 11 llamas and 1 alpaca. Medical records from a veterinary medical teaching hospital from January 1, 1995, to December 31, 2006, were reviewed. Records of all New World camelids that had detectable amounts of oleandrin in samples of serum, urine, or gastrointestinal fluid were included in the study. Descriptive statistics were used to evaluate the history, physical examination findings, clinicopathologic data, and outcome of affected camelids. 11 llamas and 1 alpaca met the inclusion criteria of the study. Either oleander plants were present where the camelids resided (n = 7) or oleander plant material was identified in the hay fed to the camelids (5). One llama was dead on arrival at the hospital, and another was euthanized upon admission because of financial concerns. Of the 10 treated camelids, 9 had evidence of acute renal failure, 7 had gastrointestinal signs, and 4 had cardiac dysrhythmias on initial evaluation. The overall mortality rate was 25%, but the mortality rate for the 10 camelids that were medically treated was 10%. In New World camelids, oleander intoxication was associated with a triad of clinical effects (ie, renal, gastrointestinal, and cardiovascular dysfunction). Oleander intoxication often represented a herd problem but carried a fair to good prognosis if treated promptly. Oleander toxicosis should be considered a differential diagnosis in sick camelids.

    Full Text Available Objective: The term “Ataxia” is used to denote disturbances of the body posture and its movement that are normally controlled by the cerebellum. frontal lobes and the posterior columns of the spinal cord. The initial symptom and the most prominent feature of ataxia is abnormal gait which is characterized by lurching and wide base walking. Knowing that, the acute ataxia is among those problems that brings very soon the child to pediatrics neurology department and in view of lack of any survey in this neid in our country, we decided to investigate the etiology of acute ataxia in Islamic Republic of Iran. Materials & Methods: Our patients were recruited from 100 children who were brought to neurology service of Mofid children hospital with the chief complaint of acute ataxia over 2 years period. (sep 2001 to sep 2003. All of those 100 patients were admitted and required investigations were performed. Results: Results of our workup revealed that the most common cause of acute ataxia is acute cerebellar one, which all of them preceded by viral febrile illness. The second frequent cause of acute. Ataxia is due to drug intoxication, which commonly was observed between 2 – 4 years period. Conclusion: The remaining etiologies in descending frequency were as follow, Infectious polyneuropathy, Migraine, Opsoclonus – Myoclonus, Brain tumor, ADEM,MS and Epilepsy.

    With increases in globalization, cultural remedies from Chinese, Ayurvedic, Arab and other traditions have become more available to international consumers, offering unfamiliar "Natural Health Products" (NHP), used as alternative medicine or supplementary medicine. Contamination with toxic ingredients including lead, mercury, arsenic, and other toxic elements has been documented in several of these products from various parts of the globe, particularly from some parts of Asia and the Orient. We have been following this development in the last 6 years and have analyzed n  = 20 such products (60 analyses) from patients with intoxication symptoms in a pilot study, showing alarming high concentrations of mercury and/or lead (the first one in "therapeutic" doses). 82 % of the studied NHP contained lead concentrations above the EU limit for dietary supplements. 62 % of the samples exceeded the limit values for mercury. Elevated blood lead and mercury levels in patients along with clinical intoxication symptoms corroborate the causal assumption of intoxication (s). We present one detailed clinical case report of severe lead and mercury intoxications and give an overview about blood concentration related symptoms and signs of n  = 41 case reports of mercury intoxications of the German monitoring BfR-DocCenter. For NHP there is evidence on a distinct toxicological risk with alarming low awareness for a possible intoxication which prevents potentially life-saving diagnostic steps in affected cases. In many cases patients do not communicate the events to their physicians or the local health authority so that case reports (e.g. the BfR-DocCentre) are missing. Thus, there is an urgent need to raise awareness and to initiate more suitable monitory systems (e.g. National Monitoring of Poisonings) and control practice protecting the public.

  20. Risk factors for the development of pneumonia in acute psychotropic drugs poisoning

    2005-01-01

    Full Text Available Background/Aim. Pneumonia is the most frequent complication in acute psychotropic drugs poisoning, which results in substantial morbidity and mortality, but which also increases the costs of treatment. Risk factors for pneumonia are numerous: age, sex, place of the appearance of pneumonia, severity of underlying disease, airway instrumentation (intubation, reintubation, etc. The incidence of pneumonia varies in poisoning caused by the various groups of drugs. The aim of this study was to determine the incidence and risk factors for pneumonia in the patients with acute psychotropic drugs poisoning. Methods. A group of 782 patients, out of which 614 (78.5% with psychotropic and 168 (21.5% nonpsychotropic drug poisoning were analyzed prospectively during a two-year period. The diagnosis of pneumonia was made according to: clinical presentation, new and persistent pulmonary infiltrates on chest radiography, positive nonspecific parameters of inflammation, and the microbiological confirmation of causative microorganisms. To analyze predisposing risk factors for pneumonia, the following variables were recorded: sex, age, underlying diseases, endotracheal intubation, coma, severity of poisoning with different drugs, histamine H2 blockers, corticosteroids, mechanical ventilation, central venous catheter. The univariate analysis for pneumonia risk factors in all patients, and for each group separately was done. The multivariate analysis was performed using the logistic regression technique. Results. Pneumonia was found in 94 (12.02% of the patients, 86 of which (91.5% in psychotropic and 8 (8.5% in nonpsychotropic drug poisoning. In the psychotropic drug group, pneumonia was the most frequent in antidepressant (47%, and the rarest in benzodiazepine poisoning (3.8%. A statistically significant incidence of pneumonia was found in the patients with acute antidpressant poisoning (p < 0.001. Univariate analysis showed statistical significance for the

    We review the evaluation and treatment of patients with drug addictions complicated by other acute or chronic diseases from the perspective of the hospital setting. The spectrum of drug addiction's complications is broad and in many instances it is predetermined by the abuse substance and its administration route. Some complications of intravenous drug addiction have dramatically decreased in the last few years as a result of a better knowledge of hygienic customs and after the implementation of some health interventions such as the provision of sterile injectable devices. Two highly prevalent infections --HIV/AIDS and hepatitis C-- remain from the period in which most HIV infections owed to the intravenous use of heroin. Of note, these two infections largely account for the survival and quality of life of those who quit their addiction. On the other hand, it is still common the hospitalization of patients with both alcohol dependence and intercurrent diseases in whom their drug addiction may pass unnoticed. Other common situations include the treatment of acute patients with cocaine addiction and psychiatric comorbidity, patients under methadone therapy and, in general, all those cases in which, in emergency, ordinary hospital wards and specialized units, a wide differential diagnosis is raised when there is a coexistence of signs and symptoms common to an addiction, infection and/or intoxication. An integral vision of drug addiction and its complications, as well as the clinical evaluation of all health problems, is fundamental for the prognosis and treatment of these patients.

  2. A Cohort Approach to Real-Time Detection of Acute HIV Infections Among People Who Inject Drugs in St. Petersburg, Russia.

    To detect acute HIV infections (AHIs) in real time among people who inject drugs (PWID) in St. Petersburg, Russia and to test the feasibility of this approach. Prospective cohort study. One hundred seronegative or acutely HIV-infected at screening PWID were enrolled and followed until the end of the 12-month pilot period. Each participant was evaluated, tested, and counseled for HIV monthly. Two HIV tests were used: HIV antibody and HIV RNA PCR. If diagnosed with AHI, participants were followed weekly for a month; then, monthly for 3 months; and then, quarterly for the duration of the follow-up period. HIV risk behavior was assessed at each study visit. Most enrolled PWID were 30-39 years old, male, completed high school or more, not employed full-time, heroin users, and frequently shared injection paraphernalia. AHI prevalence at screening was 1.8% [95% confidence interval (CI): 0.4, 5.5]. Three participants with AHI at enrollment represented 3% (95% CI: 0.6, 8.5) of the 100 participants who consented to enroll. Among the HIV-uninfected participants (n = 97), the AHI incidence over time was 9.3 per 100 person-years. Persons with AHI were more likely to report alcohol intoxication within the prior 30 days. This was the first study to detect AHI using a cohort approach. The approach proved to be feasible: recruitment, retention, AHI detection, and virological endpoints were successfully reached. A cost analysis in a real-world setting would be required to determine if this strategy could be brought to scale. The study revealed continued high HIV incidence rate among PWID in St. Petersburg, Russia and the importance of prevention and treatment programs for this group.

    This study reviewed the perceptions and strategies of drug users and nurses with regard to pain management in acute care settings. Drug users present unique challenges in acute care settings with pain management noted to be at best suboptimal, at worst non-existent. Little is known about why and specifically how therapeutic effectiveness is compromised. Qualitative: constructivist grounded theory. A constructivist grounded theory approach incorporating a constant comparative method of data collection and analysis was applied. The data corpus comprised interviews with drug users (n = 11) and five focus groups (n = 22) of nurses and recovering drug users. Moral relativism as the core category both represents the phenomenon and explains the basic social process. Nurses and drug users struggle with moral relativism when addressing the issue of pain management in the acute care setting. Drug users lay claim to expectations of compassionate care and moralise via narration. Paradoxically, nurses report that the caring ideal and mutuality of caring are diminished. Drug users' individual sensitivities, anxieties and felt stigma in conjunction with opioid-induced hyperalgesia complicate the processes. Nurses' and hospitals' organisational routines challenge drug user rituals and vice versa leading both protagonists to become disaffected. Consequently, key clinical issues such as preventing withdrawal and managing pain are left unaddressed and therapeutic effectiveness is compromised. This study provides a robust account of nurses' and drug users' struggle with pain management in the acute care setting. Quick technological fixes such as urine screens, checklists or the transient effects of (cognitive-based) education (or training) are not the answer. This study highlights the need for nurses to engage meaningfully with this perceptibly 'difficult' group of patients. The key aspects likely to contribute to problematic interactions with this patient cohort are outlined so that

    Electronic music and dance events in nightclubs attract patrons with heavy alcohol/drug use. Public health concerns are raised from risks related to these behaviors. Practices associated with increased risk in these club settings need to be identified. The relationship between club management practices and biological measures of patrons' alcohol/drug use is examined. Observational data from 25 events across six urban clubs were integrated with survey data (N = 738 patrons, 42.8% female) from patrons exiting these events, 2010-2012. Five indicators of club management practices were examined using mixed model regressions: club security, bar crowding, safety signs, serving intoxicated patrons, and isolation. Analyses revealed that serving intoxicated patrons and safety signs were related to substance use. Specifically, serving intoxicated patrons was related to heavy alcohol and drug use at exit, while safety signs were marginally related to less exit drug use. CONCLUSIONS/IMPORTANCE: Findings indicate observable measures in nightclubs provide important indicators for alcohol/drug use, suggesting practices to target. Study strengths include the use of biological measures of substance use on a relatively large scale. Limitations and future directions are discussed.

    Full Text Available Tellurium compounds may be cytotoxic to different cells types. Thus, this work evaluated the effect of diphenyl ditelluride ((PhTe2, an organotellurium commonly used in organic synthesis, on the morphology of liver, kidney, and lung. Adult mice were acutely (a subcutaneous single dose: 250 μmol/kg or subchronically (one daily subcutaneous dose: 10 or 50 μmol/kg for 7 and 14 days exposed to (PhTe2. Afterwards, the histological analyses of liver, kidney, and lungs were performed. Liver histology revealed that the hepatocytes of mice subchronically exposed to (PhTe2 presented cytoplasmic vacuolization, hydropic degeneration, and hyperchromatic nuclei. Subchronic exposure to 50 μmol/kg (PhTe2 also caused hepatic necrosis. Microvesicular and macrovesicular steatosis were identified in liver of mice acutely exposed to (PhTe2. Acute and subchronic intoxication with (PhTe2 induced changes on epithelial cells of renal tubules, namely, loss of brush border and cytoplasmatic vacuolization. Atrophy and hypertrophy, cast proteinaceous formation, and acute tubular necrosis were also identified in renal tissue. Mice subchronically exposed to 50 μmol/kg (PhTe2 developed intra-alveolar edema and alveolar wall congestion in some areas of lungs. Acute exposure to (PhTe2 did not cause histological changes in lungs. Our data show that (PhTe2 may be considered a histotoxic agent for liver, kidney, and lung.

    Because of the paucity of information on the epidemiology of acute poisoning requiring intensive medical care, all such patients treated on the medical intensive care unit of the university hospital in Frankfurt am Main, Germany, between January 1993 and December 1999, were retrospectively evaluated. Of the total of 6211 patients, 147 (80 women, 67 men, mean age 41 years, 2,3 %) were treated for acute intoxication in the intensive care unit. Reasons for admission to the intensive care unit were the need for ventilator treatment or intensive monitoring of vital functions. 52 % of the patients (n = 76) had attempted suicide, most of them using anti-depressive drugs (n = 19), paracetamol (n = 16), or benzodiazepines (n = 9). Two patients (2,6 %) died. 48 % of the patients (n = 71) were admitted because of accidental poisoning. Leading toxic agents in this group were heroin (n = 19), alcohol (n = 18) and digitalis (n = 12). 11 patients had taken herbicides, animal poisons or chemicals used at work or for house cleaning. In this cohort, three i. v. drug abusers (4,2 %) had died. Depending on the agents used, a variety of treatments (charcoal, antidots, extracorporal therapy) were undertaken. Due to excellent care in the prehospital phase and in the emergency room the number of patients requiring treatment on the intensive care unit was rather low. The mortality was in the range of other reports.

    Full Text Available Objective: to define the specific features of the psychological status of patients with acute mandibular injury, to compare a psychological reaction to injury in different age groups and in persons with signs of alcohol addiction. Subjects and methods. The study enrolled 37 patients of both sexes over 15 years of age. The patients were distributed by age and chronic alcohol intoxication. Psychological parameters were determined using personality questionnaires: Spielberg-Hanin, Zung, GHQ-28, and Wein ones. Results. The patients with mandibular injury were found to have higher levels of situational and personality anxiety. A state of depression as a response to acute mandibular injury of reactive genesis was found in 29.8% of cases. Autonomic dysfunction occurred in 62.2% of the patients with mandibular fractures. Occult pathopsychological states were detected in 35.1% of the study group patients. Conclusion. The main found peculiarities of the psychological status of the patients with acute mandibular injury were high anxiety and the considerable incidence of autonomic dysfunction syndrome. There were no great age differences in psychological status and the direction of reactions. The patients with chronic alcohol intoxication more frequently developed a depressive state, but the autonomic dysfunction syndrome was just less often encountered and pathopsychological states were less frequently found. Key words: acute low anxiety depression alcohol abuse, psychological status.

    Full Text Available Spontaneous intoxication in 34 horses after ingesting freshly harvested maize that was to be used for ensiling and heavily contaminated with young Datura stramonium plants, is described. The clinical status of all horses was monitored for 7 days, and included body (rectal temperature, respiratory and heart rates, colour and moistness of visible mucosae, changes in pupil size, appetite, thirst, general behaviour, locomotion, sensory perceptions, urination and defaecation. The intoxication was accompanied by altered clinical status, namely mild hyperthermia, tachycardia, polypnoea, dyspnoea and shallow breathing, mydriasis, dry oral, rectal, vaginal and nasal mucosae, acute gastric dilatation and severe intestinal gas accumulation, anorexia to complete refusal of feed, decreased or absent thirst, absence of defaecation and urination. As a result of the treatment, the clinical parameters normalised between days 2 and 5. Necropsies and pathological studies were performed on two horses that died, revealing toxic liver dystrophy, cardiac lesions and substantial dystrophic and necrotic processes in the kidneys. The observed clinical signs, the pathomorphological changes and the applied therapy could be used in the diagnosis, differential diagnosis, prognosis and treatment of Jimson weed intoxication.

    Full Text Available Objective: to determine the nature and specific features of development of endogenous intoxication in pregnant women with arterial hypertension. Subjects and materials. Humoral extracellular fluid volume regulation, partial renal functions, placental hormonal function, membranous lipid peroxidation activity, antiradical defense, the parameters of central hemodynamics, endogenous intoxication, and a biochemical coagulogram were studied and differential blood count with the leukocytic ratio indices was estimated in 172 pregnant females with arterial hypertension and 54 healthy pregnant ones in the third trimester. The statistical package «Stadia» was applied. Results. Arterial hypertension caused by pregnancy was ascertained to involve pathogenetically different types: low-, normal-, and high-renin ones. In pregnant women with arterial hypertension, the general pathogenetic homeostatic changes were placental hormonal imbalance, activated membranous lipid peroxidation, impaired lymph outflow, sodium and water retention, hepatic and renal failure, and endogenous intoxication. Conclusion. Placental ischemia appearing as placental hormonal imbalance (extrarenal pressor system was accompanied by a compensatory humoral response: arterial hypertension and metabolic disturbances. Changes in medium-weight molecule 280, leukocytic intoxication index, erythrocytic sorption capacity, and Paramecium test, by confirming the presence of endogenous intoxication in pregnant females with arterial hypertension, were caused by a type of arterial hypertension (by the hemodynamic profile and the type of impaired partial renal functions. Key words: pregnancy, arterial hypertension, endogenous intoxication.

    Chronic thinner intoxication is one of the most serious social problems among teenagers and young adults in Japan. The purpose of this study was to evaluate clinical characteristics of patients with thinner intoxication who had positive MR findings. During the past 4 years, cranial MR imaging of 85 patients (51 males and 34 females) with chronic thinner intoxication was done at a national psychiatric hospital. The MR imaging was performed on a 1.0-T scanner with use of standard pulse sequences including fluid-attenuated inversion recovery (FLAIR). The established characteristic MR findings of chronic thinner intoxication were observed in 8 of the 85 patients: 4 males and 4 females. The female patients tended toward emaciation and were approximately 5 years younger than the male patients. Six of the 8 patients had severe neurological symptoms such as cerebellar ataxia and decreased visual acuity. In contrast, only 3 of 77 (4%) patients with normal MR findings had mild neurological abnormalities such as tremor. If patients with chronic thinner intoxication have significant neurological symptoms, MR imaging should be performed for evaluation of brain abnormalities. Emaciated female patients may be particularly vulnerable to neurological damage caused by thinner intoxication. (orig.)

    Background/Aim. Pneumonia is the most frequent complication in acute psychotropic drugs poisoning, which results in substantial morbidity and mortality, but which also increases the costs of treatment. Risk factors for pneumonia are numerous: age, sex, place of the appearance of pneumonia, severity of underlying disease, airway instrumentation (intubation, reintubation, etc). The incidence of pneumonia varies in poisoning caused by the various groups of drugs. The aim of this study was to det...

    Acute fluoride (F - ) toxicity is known to cause severe cardiac complications and leads to sudden heart failure. Previously, we reported that increased myocardial oxidative damage, apoptosis, altered cytoskeleton and AMPK signaling proteins associated with energy deprivation in acute F - induced cardiac dysfunction. The present study was aimed to decipher the status of myocardial heat shock proteins (Hsps-Hsp27, Hsp32, Hsp40, Hsp60, Hsp70, Hsp90) and heat shock transcription factor 1 (Hsf1) in acute F - -intoxicated rats. In order to study the expression of myocardial Hsps, male Wistar rats were treated with single oral doses of 45 and 90 mg/kg F - for 24 h. The expression levels of myocardial Hsps were determined using RT-PCR, western blotting, and immunohistochemical studies. Acute F - -intoxicated rats showed elevated levels of both the transcripts and protein expression of Hsf1, Hsp27, Hsp32, Hsp60, and Hsp70 when compared to control. In addition, the expression levels of Hsp40 and Hsp90 were significantly declined in a dose-dependent fashion in F - -treated animals. Our result suggests that differential expression of Hsps in the rat myocardium could serve as a balance between pro-survival and death signal during acute F - -induced heart failure.

    2013-01-01

    Full Text Available Resulting from direct toxicity on the bowel mucosa, nonsteroidal anti-inflammatory drug (NSAID-induced colitis is an underestimated although potentially serious condition. Plain abdominal radiographs and multidetector computed tomography allow to identify a right-sided acute colitis with associated pericolonic inflammation, progressively diminished changes along the descending and sigmoid colon, and rectal sparing, consistent with the hypothesized pathogenesis of NSAID colitis. Increased awareness of this condition should reduce morbidity through both prevention and early recognition. High clinical suspicion and appropriate patient questioning, together with consistent instrumental findings, negative biochemistry, and stool investigations should help physicians not to miss this important diagnosis.

    To find drugs suitable for repositioning for use against leukemia, samples from patients with chronic lymphocytic, acute myeloid and lymphocytic leukemias as well as peripheral blood mononuclear cells (PBMC) were tested in response to 1266 compounds from the LOPAC 1280 library (Sigma). Twenty-five compounds were defined as hits with activity in all leukemia subgroups (<50% cell survival compared with control) at 10 μM drug concentration. Only one of these compounds, quinacrine, showed low activity in normal PBMCs and was therefore selected for further preclinical evaluation. Mining the NCI-60 and the NextBio databases demonstrated leukemia sensitivity and the ability of quinacrine to reverse myeloid leukemia gene expression. Mechanistic exploration was performed using the NextBio bioinformatic software using gene expression analysis of drug exposed acute myeloid leukemia cultures (HL-60) in the database. Analysis of gene enrichment and drug correlations revealed strong connections to ribosomal biogenesis nucleoli and translation initiation. The highest drug–drug correlation was to ellipticine, a known RNA polymerase I inhibitor. These results were validated by additional gene expression analysis performed in-house. Quinacrine induced early inhibition of protein synthesis supporting these predictions. The results suggest that quinacrine have repositioning potential for treatment of acute myeloid leukemia by targeting of ribosomal biogenesis

  20. Sanctified madness: the God-intoxicated saints of Bengal.

    1985-01-01

    The saintly madman is a familiar character in South Asia. To outer appearances he is no different from a lunatic, but the mad saint comes to be revered because his idiocy is popularly believed to arise from a different cause than ordinary madness. The common psychopath neglects social conventions because his consciousness is dimmed by incapacity; the saintly madman also breaches convention, but does so because his heightened consciousness has liberated him from the bonds of convention that entrap ordinary people. In the terms of Hinduism, he has tasted the divine nectar of God-realization and has returned to the human realm intoxicated by the experience. In this paper two popular God intoxicated saints of Bengal are discussed. The question is posed whether 'God intoxication' can be considered a culture-bound syndrome of Bengal. The concept of 'culture bound syndrome' is found to be too narrow to encompass the most significant issues to arise from reflection on the characteristics of the God intoxicated. These larger issues have to do with the relationship between cultural practices and models and mental states (whether deviant, as implied by the term 'syndrome' although deviance does not always carry the negative connotation implicit in 'syndrome', or normal). It is suggested that all cultures culture a limited range of mental states and thus the questions posed by the notion of culture bound syndromes are subsumed by larger questions about the relationship of all mind-states to the socio-cultural environment which conditions them. The conclusion is that God intoxication is indeed a uniquely Bengali mental condition, with variants throughout South Asia and kinship to other mystical states, but that the concept of 'syndrome' is not useful.

    Full Text Available Aim: The aim of this study was to retrospectively analyse demographic and epidemiologic characteristics, clinical course, laboratory results and prognosis of patients who were admitted to Haseki Training and Research Hospital Intensive Care Unit due to intoxication between 24.11 2007 and 21.02.2013. Methods: We evaluated age, gender, types of intoxication (accident, suicide, etiology, length of stay, mortality rate, duration of mechanical ventilation, and blood pressure, heart rate and symptoms at the time of admission. Patients who took multiple drugs were recorded. Liver and kidney function tests, blood glucose, complete blood count parameters, electrolytes and arterial blood gas values at the time of admission were evaluated. Results: A total of 59 cases of intoxication were studied. 59.7% of patients were male, 42.4% were female. The mean age was 32±13 years. 86.4% of cases occurred due to suicide attempts and 13.6%, accidentally. In our study, it was found that the most common intoxication agents were paracetamol and amitriptyline, and the most common cause of death was methyl alcohol intoxication. Conclusion: Our results showed that a significant portion of the intoxication cases admitted to the intensive care unit were young adults who attempted suicide by overdosing on drugs.

  4. GHB Pharmacology and Toxicology: Acute Intoxication, Concentrations in Blood and Urine in Forensic Cases and Treatment of the Withdrawal Syndrome

    The illicit recreational drug of abuse, γ-hydroxybutyrate (GHB) is a potent central nervous system depressant and is often encountered during forensic investigations of living and deceased persons. The sodium salt of GHB is registered as a therapeutic agent (Xyrem®), approved in some countries for the treatment of narcolepsy-associated cataplexy and (Alcover®) is an adjuvant medication for detoxification and withdrawal in alcoholics. Trace amounts of GHB are produced endogenously (0.5-1.0 mg/L) in various tissues, including the brain, where it functions as both a precursor and a metabolite of the major inhibitory neurotransmitter γ-aminobutyric acid (GABA). Available information indicates that GHB serves as a neurotransmitter or neuromodulator in the GABAergic system, especially via binding to the GABA-B receptor subtype. Although GHB is listed as a controlled substance in many countries abuse still continues, owing to the availability of precursor drugs, γ-butyrolactone (GBL) and 1,4-butanediol (BD), which are not regulated. After ingestion both GBL and BD are rapidly converted into GHB (t½ ~1 min). The Cmax occurs after 20-40 min and GHB is then eliminated from plasma with a half-life of 30-50 min. Only about 1-5% of the dose of GHB is recoverable in urine and the window of detection is relatively short (3-10 h). This calls for expeditious sampling when evidence of drug use and/or abuse is required in forensic casework. The recreational dose of GHB is not easy to estimate and a concentration in plasma of ~100 mg/L produces euphoria and disinhibition, whereas 500 mg/L might cause death from cardiorespiratory depression. Effective antidotes to reverse the sedative and intoxicating effects of GHB do not exist. The poisoned patients require supportive care, vital signs should be monitored and the airways kept clear in case of emesis. After prolonged regular use of GHB tolerance and dependence develop and abrupt cessation of drug use leads to unpleasant

    The recreational usage of dextrometorphan, the popular antitussive medicine, has become alarming in Poland. The euphoric and hallucinogenic activity of this drug manifests after high doses, usually ranging from 225 to 1500 mg that may lead to acute poisoning. Currently, dextrometh-orphan is considered as addictive substance. In this article we describe the symptoms of acute dextrometorphan poisoning that have been observed in 11 patients, aged between 16 and 31 years that have been treated in the Department of Toxicology and Internal Diseases Raszeja Hospital in Poznan. In the course of intoxication the most frequent symptom was balance disturbation (12.50%), impaired motoric coordination (11.36%), confusion (11.36%) and papillary dilation (11.36%). Agitation (9.09%), tachycardia (7.95%), hallucinations (6.82%), disartria (5.68%) and hypertension (4.55%) were less common. The doses of dextromethorphan ranged from 4.28 to 16.67 mg/kg. All the patients were treated symptomatically. They recovered without sequelae and were discharged after 1-3 days of hospitalization.

    The amount of necrotic myocardium following acute coronary artery occlusion influences both the early and long-term consequences of myocardial infarction. Experiments, however, indicate that several drugs given early after the occlusion can substantially alter final infarct size. Clinical assessment of the effects of these drugs poses difficulties and an awareness of the limitations of existing methods is essential for their successful application. This discussion is restricted largely to the advantages and disadvantages of the three main methods currently used for assessing acute myocardial infarct size:-praecordial electrocardiographic mapping, serial estimates of serum creatine kinase activity, and radionuclide scintigraphy.

    Chronic exposure to cadmium (Cd) results in bicarbonaturia, leading to metabolic acidosis. To elucidate the mechanism(s) by which renal bicarbonate reabsorption is inhibited, we investigated changes in renal transporters and enzymes associated with bicarbonate reabsorption in Cd-intoxicated rats. Cd intoxication was induced by subcutaneous injections of CdCl 2 (2 mg Cd/kg per day) for 3 weeks. Cd intoxication resulted in a significant reduction in V max of Na + /H + antiport with no changes in K Na in the renal cortical brush-border membrane vesicles (BBMV). Western blotting of BBM proteins and indirect immunohistochemistry in renal tissue sections, using an antibody against Na + /H + exchange-3 (NHE3), showed a diminished expression of NHE3 protein in the BBM. Reverse transcription-polymerase chain reaction (RT-PCR) analysis revealed that NHE3 mRNA expression was reduced in the renal cortex. The activity of carbonic anhydrase IV (CA IV) in BBM was not changed. The protein abundance of Na + -HCO 3 - cotransporter-1 (NBC1) in whole kidney membrane fractions was slightly attenuated, whereas that of the Na + -K + -ATPase α-subunit was markedly elevated in Cd-intoxicated animals. These results indicate that Cd intoxication impairs NHE3 expression in the proximal tubule, thereby reducing the capacity for bicarbonate reabsorption, leading to bicarbonaturia in an intact animal

    Objective: To investigate the imaging of CT and MRI in brain damage caused by methanol intoxication from false wine, and to study the relations between imaging manifestation and different degrees of the methanol intoxication. Method: Thirty nine cases with methanol intoxication from false wine were retrospectively reported, The latent period of these patients was 0-4 days, and the average latent period of these patients was 0.5 days, All cases were performed by serology examination, brain CT scan, and four cases performed by MRI scan after average 2.5 days (range, 1-6 days) the onset of methanol intoxication. Results: Six cases showed hyperintense signals in bilateral putamen, two cases also showed hyperintense signals in biolateral subcortex white substance regions. Four cases showed hyperintense signals in unilateral internal capsule. One case showed hyperintense changess in subcortex white substance regions. Our study showed the positive correlation between CT features and the amount of methanol and stage of clinic manifestation(χ 2 =4.232, P 2 =0.001, P>0.05). Conclusions: MRI was better than CT in finding early brain damage caused by methanol intoxication from false wine. The characteristic finding changes of the patients was showed mainly in in bilateral putamen, Prognosis for the patients combined with subcortex white substance lesion wasn't hopeful. (authors)

    We investigated the changes in key parameters of carbohydrate and lipid metabolism, which correspond to the clinical picture that accompanies the development of prediabetic condition on the background of chronic alcohol intoxication. From the analysis of glycemic curves obtained during the insulin-glucose test, a speed of glucose uptake by peripheral tissues increased at the 1st day (1.5 fold) and the third day (1.3 fold) of administration of alcohol solution. At the later periods, at 7 and 11 days of ethanol administration, a decreased rate of glucose uptake in animals with chronic alcohol intoxication was detected. We also detected an increased content of serotonin in the blood serum and a decreased (1.2 fold) serotonin content in rat brain during the whole period of development of chronic alcohol intoxication.

    2007-01-01

    Full Text Available Objective: to study the specific features of the diagnosis and treatment of endothoxicosis as a manifestation of postresus-citative disease in acute exogenous poisoning.Subjects and methods. Clinical, laboratory, and statistical methods of the diagnosis of endotoxicosis complicating the course of acute poisoning by narcotics, psychopharmacological agents, and cauterants, as well as complex physicochemical detoxification were applied to 554 patients.Results. The study pathology has been ascertained to have 3 developmental stages — from functional (primary to developed and terminal clinical and laboratory manifestations as multiple organ dysfunctions. The best therapeutic results are achieved by effective therapeutic measures just in early-stage endotoxicosis, by substantially reducing the rates of death and pneumonia and the time of the latter’s resolution. The major contribution to the reduction in the rate of death due acute poisoning is associated with physicochemical detoxification that considerably lessens the influence of the intoxication factors of postresuscitative disease.Conclusion. When diagnosing endotoxicosis in patients with acute endogenous intoxication, it is necessary to keep in mind a whole spectrum of typical changes in endotoxicosis markers and homeostatic parameters: hematologi-cal, blood rheological, lipid peroxidation/antioxidative systems, which should be timely corrected by the basic efferent artificial detoxification techniques (hemosorption, hemodiafiltration, hemofiltration, by compulsorily employing physio-and chemohemotherapy (laser-ultraviolet hemotherapy, sodium hypochlorite infusion.

    Star fruit (SF) is a commonly available fruit produced and eaten in tropical and subtropical countries. Since 1993, various reports have described neurotoxicity after eating SF, but this clinical condition remains unfamiliar. We aimed to describe this clinical entity, the role of renal dysfunction in this disorder, treatment strategies, and prognosis of patients with SF intoxication. We conducted a search of PubMed and Google Scholar databases from 1993 to 2016. We included reports describing patients with a clear history of SF ingestion with acute symptoms. We described the demographic characteristics, reported SF intake, treatments used, and outcomes. We reviewed totally 126 patients (male:female = 1.5:1) from 33 articles with mean age 54.4 ± 11 (range: 30-84). The most common symptom was hiccups (65%), whereas confusion and seizure were the most common symptoms associated with mortality (42% and 61%, respectively). Pre-intoxication renal function also affected mortality. While there was no mortality in patients with normal renal function (NRF), the mortality of patients among reported cases with chronic renal insufficiency and end-stage renal disease undergoing dialysis were 36% and 27%, respectively. With the inclusion of patients reported to have NRF, the overall mortality was 24%. Consistently, the number of SF consumed was substantially higher in the patients with NRF than those with renal functional impairment. The most common treatment strategy was hemodialysis (59%). Patients with impaired renal function were at higher risks of SF intoxication. Severe neurologic symptoms mandate immediate medical intervention because of the association between their occurrence and high mortalities. Toxin removal through dialysis, rather than symptomatic relief, seems to be beneficial to patient survival. Early and continuous dialysis appears to alleviate severe symptoms and prevent symptom rebounds.

  15. Gender differences in natural language factors of subjective intoxication in college students: an experimental vignette study.

    Examining the natural language college students use to describe various levels of intoxication can provide important insight into subjective perceptions of college alcohol use. Previous research (Levitt et al., Alcohol Clin Exp Res 2009; 33: 448) has shown that intoxication terms reflect moderate and heavy levels of intoxication and that self-use of these terms differs by gender among college students. However, it is still unknown whether these terms similarly apply to other individuals and, if so, whether similar gender differences exist. To address these issues, the current study examined the application of intoxication terms to characters in experimentally manipulated vignettes of naturalistic drinking situations within a sample of university undergraduates (n = 145). Findings supported and extended previous research by showing that other-directed applications of intoxication terms are similar to self-directed applications and depend on the gender of both the target and the user. Specifically, moderate intoxication terms were applied to and from women more than men, even when the character was heavily intoxicated, whereas heavy intoxication terms were applied to and from men more than women. The findings suggest that gender differences in the application of intoxication terms are other-directed as well as self-directed and that intoxication language can inform gender-specific prevention and intervention efforts targeting problematic alcohol use among college students.

    A wide range of commonly abused drugs have effects on the noradrenergic neurotransmitter system, including alterations during acute intoxication and chronic use of these drugs. It is not established, however, that individual differences in noradrenergic signaling, which may be present prior to use of drugs, predispose certain persons to substance abuse. This paper puts forth the novel hypothesis that elevated noradrenergic signaling, which may be raised largely due to genetics but also due to environmental factors, is an etiological factor in the abuse of a wide range of substances, including alcohol, nicotine, marijuana, heroin, cocaine, and caffeine. Data are reviewed for each of these drugs comprising their interaction with norepinephrine during acute intoxication, long-term use, subsequent withdrawal, and stress-induced relapse. In general, the data suggest that these drugs acutely boost noradrenergic signaling, whereas long-term use also affects this neurotransmitter system, possibly suppressing it. During acute withdrawal after chronic drug use, noradrenergic signaling tends to be elevated, consistent with the observation that norepinephrine lowering drugs such as clonidine reduce withdrawal symptoms. Since psychological stress can promote relapse of drug seeking in susceptible individuals and stress produces elevated norepinephrine release, this suggests that these drugs may be suppressing noradrenergic signaling during chronic use or instead elevating it only in reward circuits of the brain. If elevated noradrenergic signaling is an etiological factor in the abuse of a broad range of substances, then chronic use of pharmacological agents that reduce noradrenergic signaling, such as clonidine, guanfacine, lofexidine, propranolol, or prazosin, may help prevent or treat drug abuse in general.

    Despite the risks involved when mixing alcohol with casual sexual activity, the majority of college students engage in hookups, and the majority of those hookups involve alcohol. This study focused on the protective role college students' peers can play and the situational factors that might influence their willingness to intervene when a close friend is about to hook up intoxicated. Drawing on the theory of planned behavior (TPB), this study investigated differences in students' (N = 1270) attitudes, norms, perceived behavioral control, and intentions to persuade a close friend not to engage in a hypothetical drunken hookup using a 2 (friend sex) × 2 (participant sex) × 2 (sober/intoxicated) factorial design. Results indicated significant differences in the TPB variables. Participants intended to intervene with female friends, but not male friends, and women were more likely to intervene than men. Participants in the sober condition had stronger intentions to intervene than those in the intoxicated condition, but this effect was driven by increases in men's intentions when sober. Implications for theory and prevention programming are discussed.

    Following a line of work we studied 1,140 acute poisoning (AP) attended at the Internal Medicine Emergency Department at 12 de Octubre Hospital, Madrid, in 1997. The incidence increased up to 157/100,000 inhabitants. Mean age was 36 years (SD: 15 y), median, 32 years. Self-inflicted AP: 1,052 cases (92%); the suicide attempt was the most common type (509, 48%). Among males, the alcoholic intoxication (332, 59%) predominated. Among accidental AP (88 cases), 90% occurred at home. Poisons: drugs. Drugs were used for 78% of suicide attempts. The relative incidence of benzodiazepines increased (47%) and that of antidepressive drugs decreased (11%). A remarkable increase in the "other drugs" group was noted, as well as the association of drugs and non-drugs (10%). Alcohol use increased significantly (249 cases more than in 1994), as well as drugs although to a lesser extent, breaking the trend observed in the last few years. Cocaine is now the most common (among women heroin is still the leading cause); 5 AP were caused by synthesis drugs (extasis, MDMA) and an increase was observed with "other drugs". suicide attempts: depression (30%) and previous attempts (19%); ethylism: alcoholism (40%); AP with other drugs: drug abuse (52%). Admitted to ICU: 1.4%. The mortality rate decreased to 0.08%.

    Changes in rectal and toe temperatures were measured in 16 patients who had been intoxicated with short-acting barbiturates. The lowest temperatures observed in the group of 16 patients averaged 35.5 +/- 2.0 degrees C. In 11 patients, the interval between intoxication and admission was documented. There was a significant correlation (r = 0.83) between the time of estimated intoxication and hypothermia. Patients who were admitted soon after the ingestion of the barbiturates had the lowest rectal temperatures. These observations indicate that hypothermia is a usual clinical sign in the initial period after intoxication with a short-acting barbiturate. Except for 2 patients, rectal temperature exceeded 38 degrees C during the interval of recovery with the maximum rectal temperature averaging 39.0 +/- 0.8 degrees C. Hyperthermia was not related to infection of the airways, lungs, urinary tract, or bloodstream. In 11 patients, pathogenic organisms were recovered from the airway and/or urine, but there was no difference in the highest rectal temperature in these patients (39.0 +/- 0.9 degrees C) when compared with 5 patients from whom no pathogenic organisms were recovered (39.2 +/- 0.7 degrees C). Accordingly, there was no evidence that hyperthermia was due to infection. The skin temperatures of the ventrum of the first toe were not typically decreased during hypothermia. To the contrary, increases in skin temperatures were often observed during hypothermia. These observations provide evidence of altered thermoregulation with increased surface heat loss accounting for the hypothermia in the early course and heat conservation with hyperthermia during the later course of intoxication by short-acting barbiturates.

    Of 38 children investigated between 1966 and 1971 who had a blood lead concentration greater than 37 μg/100 ml eight had encephalopathy and one died; all these eight had a blood lead concentration of 99 μg/100 ml or above. Blood lead levels are related to haemoglobin concentrations and anaemia is common in children with blood lead concentrations of 37-60 μg/100 ml, levels previously accepted as harmless. Children with blood lead concentrations greater than 60 μg/100 ml show radiological evidence of lead intoxication, and treatment for this should be considered when blood lead concentration exceeds 37 μg/100 ml. Children presenting with unexplained encephalopathy should be radiographed for evidence of lead intoxication. ImagesFIG. 2FIG. 1 PMID:4691065

  6. Paraquat intoxication and associated pathological findings in three dogs in South Africa

    Directory of Open Access Journals (Sweden)

    June H. Williams

    2016-11-01

    Full Text Available Paraquat is a bipyridylium non-selective contact herbicide commonly used worldwide. When ingestion occurs by humans and animals either accidentally, intentionally or maliciously, paraquat selectively accumulates in the lungs resulting in the production of oxygen-free radicals, causing membrane damage and cell death. Intoxicated subjects typically show progressive and fatal pulmonary haemorrhage, collapse and oedema. In individuals surviving the acute phase, pulmonary fibrosis develops. Gastrointestinal-, renal- and central nervous system clinical signs may also occur. Owing to the lack of effective treatment and absence of an antidote, the prognosis is poor. The clinical presentation, clinicopathological findings and treatment are briefly described of three dogs from one South African household, intoxicated with paraquat. Macroscopic and microscopic lesions in one dog that was necropsied, as well as pulmonary ultrastructure are detailed and illustrated for academic reference. All dogs presented with tachypnoea and dyspnoea 2–3 days after accidental paraquat ingestion. Treatment was aimed at reducing gastrointestinal absorption, enhancing elimination by diuresis and avoiding further oxidative damage by administration of antioxidants. All dogs, however, became progressively hypoxic despite treatment and were euthanised. Paraquat toxicity should be a differential diagnosis in dogs with unexplained progressive respiratory and gastrointestinal signs and renal failure. The local veterinary profession should be aware of accidental or intentional paraquat toxicity of animals. Existing literature, variations possible in canine clinical signs, measured parameters, lesions, as well as possible treatments, promising experimental antidotes and management options are discussed.

    Liver is the main site in the body for intense metabolism and excretion. A number of chemicals and drugs which are used routinely cause liver damage. The present study investigates the antihepatotoxic effect of Physalis peruviana whole ripe fruit, water and ethanol extracts of fruit in normal as well as in carbon tetrachloride (CCl(4)) intoxicated rats. The CCl(4) treated rats showed marked elevation in liver enzymes: alanine transaminse, aspratate transaminase, alkaline phosphatase, lactate dehydrogenase and other biochemical parameters: bilirubin, creatinine and urea, thus indicating liver injury. Whereas animal treated/fed with various preparations of Physalis peruviana showed significant lowering effect (pPhysalis peruviana showed highest activity in both rat models while ripe fruit and ethanol extract showed moderate activity compared to standard drug.

    Preventive measures in Central Europe were successful in suppressing both occupational and environmental lead exposure so that they did not constitute a severe public health problem. However, rare lead intoxications still appear. We report on lead intoxication in four family members where the source was removed lead ceiling paint. The symptoms of the lead intoxication started several weeks after removal and the inhalational exposure to the minimum dust residues lasted for more than three months before the poisoning was diagnosed. Father developed anaemia and saturnine colics. He and his two daughters received antidotal treatment which had to be repeated in the children. Finally, all recovered completely.Lead intoxication may be easily overlooked due to the unspecific symptoms. It is necessary to think of this rare poisoning which may be caused by old paints, historical ceramics and lead shots, in addition to commercial products imported from abroad.

    Objective: Due to depressant effects of methanol on the central nervous system, brain computed tomography (CT) scan has been introduced as a diagnostic device in methanol intoxication. The authors aimed to present brain CT findings in patients with acute methanol intoxication and to determine signs associated with death. Materials and methods: This cohort study involved 42 consecutive patients with acute methanol intoxication. Inclusion criteria were consisted of characteristic clinical presentation of methanol poisoning, and metabolic acidosis with increased anion and osmolar gaps. Brain CT scans without contrast medium were obtained. To determine the association between the CT findings and death, the chi-square test or the Fisher's exact test, odds ratio (OR) and its 95% confidence interval (95% CI) were calculated. Results: Twenty-eight patients (66.6%) had a total of 55 abnormal findings on brain CT, in which bilateral putaminal hypodense lesions was the most common manifestation (27 cases, 96.4%). Putaminal hemorrhage with varying degrees was observed in 7 patients (25%). Six patients (21.4%) had low attenuation lesions in the subcortical white matter of the insula. A significant association was observed between putaminal hemorrhage (OR = 8, 95% CI = 1.187-53.93, P = 0.018) and subcortical necrosis of the insula (OR = 11, 95% CI = 1.504-80.426, P = 0.007) with death. Conclusion: In addition to clinical and laboratory findings, presence of putaminal hemorrhage and insular subcortex white matter necrosis are associated with a poor clinical outcome in patients with methanol poisoning.

    Full Text Available Objectives: Carbon monoxide is a potentially fatal form of poisoning. The exact incidence is unclear, due to cases being undiagnosed or reported as fewer than the real number. Hyperbaric oxygen therapy (HBOT is of proven efficacy in the treatment of CO intoxication.The purpose of this study was to describe the general characteristics of carbon monoxide (CO intoxications presenting to the emergency department and to investigate troponin I values and the effectiveness of hyperbaric oxygen therapy (HBOT in these patients. Material and methods: Patients presenting to the emergency department with CO intoxication over one year and patients with such intoxications receiving HBOT were examined retrospectively. Results: One hundred seventy-one patients were included; 140 (81.9% were poisoned by stoves, 18 (10.5% by hot water boilers and 10 in (5.8% by fires. COHb levels were normal in 49 of the 163 patients whose values were investigated, and were elevated in 114 patients. Mean COHb value was 16.6. Troponin I values were investigated in 112 patients. These were normal in 86 patients and elevated in 26. Mean troponin I value was 0.38 ng/ml. One hundred twenty-three of the 171 patients in the study were discharged in a healthy condition after receiving normobaric oxygen therapy, while 48 patients received HBOT. Forty-two (87.5% of the patients receiving HBOT were discharged in a healthy condition while sequelae persisted in five (10.4%. One patient died after 15 session of HBOT. Conclusion: Although elevated carboxyhemoglobin confirms diagnosis of CO intoxication, normal levels do not exclude it. Troponin I levels may rise in CO intoxication. No significant relation was observed between carboxyhemoglobin and receipt of HBOT. A significant correlation was seen, however, between troponin I levels and receipt of HBOT.

    Alcohol intoxication among spectators at sporting events and related problems, such as violence, are of great concern in many countries around the world. However, knowledge is scarce about whether or not alcohol is served to obviously intoxicated spectators at licensed premises inside and outside the sporting arenas, and if obviously intoxicated spectators are allowed entrance to these events. The objective of this study was therefore to examine the occurrences of overserving at licensed premises inside and outside arenas, and of allowed entry of obviously intoxicated spectators into arenas. An observational study assessing the rate of denied alcohol service and denied entry to arenas of trained professional actors portraying a standardized scene of obvious alcohol intoxication (i.e., pseudo-patrons) was conducted. The scene was developed by an expert panel, and each attempt was monitored by an observer. The settings were 2 arenas hosting matches in the Swedish Premier Football League in the largest city in Sweden and 1 arena in the second largest city, including entrances and licensed premises inside and outside the arenas. The rates of denied alcohol service were 66.9% at licensed premises outside the arenas (n = 151) and 24.9% at premises inside the arenas (n = 237). The rate of denied entry to the arenas (n = 102) was 10.8%. Overserving and allowed entry of obviously alcohol-intoxicated spectators are problematic at sporting events in Sweden and may contribute to high overall intoxication levels among spectators. The differences in server intervention rates indicate that serving staff at licensed premises inside the arenas and entrance staff are not likely to have been trained in responsible beverage service. This result underscores the need for server training among staff at the arenas. Copyright © 2017 by the Research Society on Alcoholism.

    Synthetic biology holds promise to engineer systems to treat diseases. One critical, yet underexplored, facet of designing such systems is the interplay between the system and the pathogen. Understanding this interplay may be critical to increasing efficacy and overcoming resistance against the system. Using the principles of synthetic biology, we engineer a strain of Escherichia coli to attract and intoxicate the nematode Caenorhabditis elegans. Our bacteria are engineered with a toxin module, which intoxicates the nematode upon ingestion, and an attraction module, which serves to attract and increase the feeding rate of the nematodes. When independently implemented, these modules successfully intoxicate and attract the worms, respectively. However, in combination, the efficacy of our bacteria is significantly reduced due to aversive associative learning in C. elegans. Guided by mathematical modeling, we dynamically regulate module induction to increase intoxication by circumventing learning. Our results detail the creation of a novel nematicidal bacterium that may have application against nematodes, unravel unique constraints on circuit dynamics that are governed by C. elegans physiology, and add to the growing list of design and implementation considerations associated with synthetic biology.

    Plant intoxications account for 5% of all intoxication cases according to French anti-poison centers. We report an uncommon case of intoxication with deadly nightshade (Atropa belladonna) in a 2-year-old child. The child presented at the ER with an atropinic syndrome, both central and peripheral, after ingestion of wild berries a few hours before. The fruit and leaves brought in by the mother allowed the anti-poison center to identify belladonna, in agreement with clinical findings. The child was kept in the intensive care unit for 48 h and progression was favorable with symptomatic treatment. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    Synthetic cannabinoids are designer drugs that mimic the effect of cannabis, which has become popular with young drug users. These drugs have a similar chemical structure and pharmacologic effects as marijuana, but seem to be more potent. These substances have been banned by the US Drug Enforcement Agency in 2010. Prior to 2010, these drugs were perceived as "safer" by the general population. Synthetic cannabinoids cause effects similar to marijuana making the subjects euphoric. However, they act as full, rather than partial, agonist at the receptor sites causing more severe side effects such as severe agitation, seizures, acute renal failure, and lactic acidosis.

    Full Text Available The aim of this study was to evaluate HRV in children requiring intensive care unit stays due to TCA poisoning between March 2009 and July 2010. In the time-domain nonspectral evaluation, the SDNN (P<0.001, SDNNi (P<0.05, RMSDD (P<0.01, and pNN50 (P<0.01 were found to be significantly lower in the TCA intoxication group. The spectral analysis of the data recorded during the first 5 minutes after intensive care unit admission showed that the values of the nLF (P<0.05 and the LF/HF ratio (P=0.001 were significantly higher in the TCA intoxication group, while the nHF (P=0.001 values were significantly lower. The frequency-domain spectral analysis of the data recorded during the last 5 minutes showed a lower nHF (P=0.001 in the TCA intoxication group than in the controls, and the LF/HF ratio was significantly higher (P<0.05 in the intoxication group. The LF/HF ratio was higher in the seven children with seizures (P<0.001. These findings provided us with a starting point for the value of HRV analysis in determining the risk of arrhythmia and convulsion in TCA poisoning patients. HRV can be used as a noninvasive testing method in determining the treatment and prognosis of TCA poisoning patients.

    Acute heart failure (AHF) is a major burden disease, with a complex physiopathology, unsatisfactory diagnosis, treatment and a very poor prognosis. In the last two decades, a number of drugs have progressed from preclinical to early and late clinical development, but only a few of them have been approved and added to a stagnant pharmacological armamentarium. We have reviewed the data published on drugs developed for AHF since early 2000s, trying to recognise factors that have worked for a successful approval or for the stoppage of the program, in an attempt to delineate future trajectories for AHF drug development. Our review has identified limitations at both preclinical and clinical levels. At the preclinical level, the major shortcoming is represented by animal models looking at short-term endpoints which do not recapitulate the complexity of the human disease. At the clinical level, the main weakness is given by the disconnect between short-term endpoints assessed in the early stage of drug development, and medium-long-term endpoints requested in Phase 3 for regulatory approval. This is further amplified by the lack of validation and standardisation of short- and long-term endpoints; absence of predictive biomarkers; conduct of studies on heterogeneous populations; and use of different eligibility criteria, time of assessments, drug schedules and background therapies. Key goals remain a better understanding of AHF and the construction of a successful drug development program. A reasonable way to move forward resides in a strong collaboration between main stakeholders of therapeutic innovation: scientific community, industry and regulatory agencies.

  1. ROLE OF ENTEROSORPTION IN COMPREHENSIVE THERAPY FOR ACUTE RESPIRATORY DISEASES COMBINED DAMAGE TO WITH GASTROINTESTINAL TRACT DISEASE

    Full Text Available The frequency of acute respiratory infections remains high in childhood. It is impossible to identify etiology most accurately in each particular case. However, according to multiple studies, viruses, their associations with each other and bacteria prevail as causative agents. In addition, it is quite often that a respiratory infection, especially in minor children, is combined with a condition of the gastrointestinal tract. Apart from symptomatic and antiviral therapies in these cases, as the authors of this article demonstrated, it is advisable to use enterosorbents. This tactics results in a decreased level of intoxication, lower intensity and duration of diarrheal syndrome, i.e. more speedy recovery.Key words: acute respiratory infections, condition of gastro tract, intoxication, diarrheal syndrome, treatment, enterosorbents, children.

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

    Full Text Available The most important reasons of acute pancreatitis (AP are benign biliary tract diseases, metabolic diseases and alcoholism. Some drugs also(sulfonamides, thiazides, lysinopril, captopril, estrogens and tetracyclines can induce AP. We herein report four cases of AP patients who were using different drugs. The first case was 73 years old male patient who has been using zofenopril for 4 weeks and the second patient was 24 years old female who was using furosemide after her pregnancy. Third one was using valsartan for one month. Fourth patient was using lysinopril for six weeks and resulted in AP. All patients had no known risk factors for pancreatitis. After cessation of the drugs, four patients recovered in a few days without any complications. AP due to zofenopril was firstly reported in our manuscript in the literature.

    Intoxication with Aconitum napellus is rare in our regions. Aconite alkaloids can cause ventricular arrhythmia by a prolonged activation of sodium channels. Because the margin of safety is low between the analgesic and toxic dose, intoxication is not rare when Aconite is used in herbal medicine. We present a case in which a 39-year-old male was accidentally intoxicated with Aconite. Even though no antidote or adequate therapy is available he was successfully resuscitated.

    Full Text Available Aims: To help clinicians to identify the severity of Alcohol Use Disorders (AUD from optimal thresholds found for recommended scales. Especially, taking account of the high prevalence of alcohol dependence among patients admitted to the Emergency Department (ED for acute alcohol intoxication (AAI, we propose to define thresholds of severity of dependence based on the AUDIT score.Methods: All patients admitted to the ED with AAI (blood alcohol level >0.8g/L, in a two-month period, were assessed using the CAGE, RAPS-QF and AUDIT, with the alcohol dependence/abuse section of the Mini International Neuropsychiatric Interview (MINI used as the gold standard. To explore the relation between the AUDIT and the MINI the sum of the positive items on the MINI (dependence as a quantitative variable and as an ordinal parameter were analyzed. From the threshold score (TS found for each scale we proposed intervals of severity of Alcohol Use Disorders (AUDs. Results: The mean age of the sample (122 males, 42 females was 46 years. Approximately 12 % of the patients were identified with alcohol abuse and 78 % with dependence (DSM-IV. Cut points were determined for the AUDIT in order to distinguish mild and moderate dependence from severe dependence. A strategy of intervention based on levels of severity of AUD was proposed. Conclusion: Different thresholds proposed for the CAGE, RAPS4-QF and AUDIT could be used to guide the choice of intervention for a patient: brief intervention, brief negotiation interviewing or longer more intensive motivational intervention.

  9. Peganum harmala L. Intoxication in a Pregnant Woman

    Full Text Available Peganum harmala L. is a plant widely distributed in the Mediterranean region. It is commonly used in traditional medicine in Morocco as sedative and abortifacient but exposes users to the risk of overdose and poisoning. The pharmacologically active compounds of this plant include a number of β-carboline and quinazoline alkaloids responsible of its pharmacological and toxicological effects. We report the case of a 24-year-old woman, 22 weeks pregnant, intoxicated with the seeds of Peganum harmala L. On admission, she had disturbance of consciousness, uterine contraction, and oliguria. Laboratory tests revealed renal failure and liver injury, and she benefited then from hemodialysis. During hospitalization, she was intubated after deterioration of consciousness and presented a spontaneous expulsion of the fetus. After extubation, she kept unusual sequelae: cerebellar ataxia and peripheral polyneuropathy. Physicians in regions using Peganum harmala L. as traditional medicine must be able to detect symptoms of its toxicity, in order to establish early gastrointestinal decontamination. The prognosis of this intoxication is variable; most cases can be managed successfully; but in high doses of intoxication, evolution can be fatal.

    Full Text Available Abstract Background Pesticide use and its consequences are of concern in Bolivia due to an intensive and increasing use. Methods To assess the magnitude and reasons for occupational pesticide intoxication, a cross-sectional study with interviews and blood-tests was performed among 201 volunteer farmers from 48 villages in the temperate and subtropical valleys in the eastern part of the Andes Mountains in Bolivia. Of these 171 male farmers using pesticides in their agricultural production were used in the statistical analysis, including linear- and logistic regression analysis. Results This study documented a frequent use of the most toxic pesticides among farmers who have had almost no instructions in how to use pesticides and protect themselves against the dangers of intoxication, reflected in the hazardous practices used when handling pesticides. Symptoms of intoxications were common in connection with spraying operations. The risk of experiencing symptoms and the serum cholinesterase activity were influenced by whether or not organophosphates were used and the number of times sprayed. The experience of symptoms was moreover influenced by the hygienic and personal protective measures taken during spraying operations while this had no influence on the serum cholinesterase level. Conclusion The study showed that occupational pesticide intoxications were common among farmers and did depend on multiple factors. Pesticide use is probably one of the largest toxicological problems in Bolivia, and a coordinated action by authorities, society and international bodies is needed to limit the number of intoxications and the environmental pollution.

  11. Chronic intoxication with copper in sheep: prophylaxis and treatment

    Energy Technology Data Exchange (ETDEWEB)

    Tomov, A

    1964-01-01

    In the period 1961-1962 chronic intoxication of sheep with copper was observed on 7 farms, the number of sheep totaling about 9000. In one of the flocks intoxication occurred after feeding the sheep for a long time with aftermath collected from orchards which had been sprinkled with copper compounds. The aftermath was proven to contain from 11 to 17 mg. per cent of copper. The other flocks were put to pasture in vineyards after the grapes had been gathered. Intoxication in these flocks was caused by vineleaves. No accumulation of copper through the soil was established in the investigated fresh grass found in the vineyards and which the sheep had also grazed. From 36 to 81 mg. per cent of copper was established in the livers of dead sheep. In order to protect the sheep from this intoxication, 100-200 mg. of ammonium or sodium molybdate and 5-10 g. of sodium sulfate were used in the case of each sheep daily for 2-3 weeks. The concentrated fodder of the sheep was moistened with an aqueous solution of these compounds. A very good prophylactic effect was obtained. At the same time oats, maize, oilcakes and others, which constitute a fodder rich in fats, were eliminated from the food rations of the sheep. The above substances, given at larger doses simultaneously with vitamin B/sub 12/ were also used for the treatment of diseased sheep, and of 10 ill sheep, 7 recovered.

  12. Methamphetamine and MDMA: ‘Safe’ drugs of abuse

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Methamphetamine and MDMA have been called safe drugs of abuse. Worldwide there is an increased consumption of these drugs, which has become a focus of research in South Africa. As the number of methamphetamine users has increased in many African countries, it is essential that emergency care practitioners are able to diagnose and manage intoxication with methamphetamine, MDMA, and other derivatives. The most common presentations include restlessness, agitation, hypertension, tachycardia, and headache while hyperthermia, hyponatraemia, and rhabdomyolysis are among the most common serious complications. Most deaths are secondary to hyperthermia complicated by multiple organ failure. A number of laboratory analyses should be obtained if locally available. We provide a review of the current recommended general and specific management approaches. Benzodiazepines are the first line therapy for hyperthermia, agitation, critical hypertension, and seizures. Patients with serious complications are best managed in an intensive care unit if available. Emergency centres should create protocols and/or further train staff in the recognition and management of intoxication with these ‘not so safe’ drugs.

  14. Indolealkylamines: biotransformations and potential drug-drug interactions.

    Yu, Ai-Ming

    2008-06-01

    Indolealkylamine (IAA) drugs are 5-hydroxytryptamine (5-HT or serotonin) analogs that mainly act on the serotonin system. Some IAAs are clinically utilized for antimigraine therapy, whereas other substances are notable as drugs of abuse. In the clinical evaluation of antimigraine triptan drugs, studies on their biotransformations and pharmacokinetics would facilitate the understanding and prevention of unwanted drug-drug interactions (DDIs). A stable, principal metabolite of an IAA drug of abuse could serve as a useful biomarker in assessing intoxication of the IAA substance. Studies on the metabolism of IAA drugs of abuse including lysergic acid amides, tryptamine derivatives and beta-carbolines are therefore emerging. An important role for polymorphic cytochrome P450 2D6 (CYP2D6) in the metabolism of IAA drugs of abuse has been revealed by recent studies, suggesting that variations in IAA metabolism, pharmaco- or toxicokinetics and dynamics can arise from distinct CYP2D6 status, and CYP2D6 polymorphism may represent an additional risk factor in the use of these IAA drugs. Furthermore, DDIs with IAA agents could occur additively at the pharmaco/toxicokinetic and dynamic levels, leading to severe or even fatal serotonin toxicity. In this review, the metabolism and potential DDIs of these therapeutic and abused IAA drugs are described.

    Baclofen is an agonist of peripheral and central B gamma-aminobutyric acid receptors, whose activation causes a myorelaxation and a powerfull depression of the central nervous system. Moreover, it has an action against addiction, in reducing craving. Commercialized since 1975 in France, to control muscle spasticity due to medullar affection or multiple sclerosis, it receives a temporary recommendation of use in march 2014, as a last-line adjuvant treatment in alcohol withdrawal. Beyond its therapeutic use, baclofen is involved in many self-induced intoxications. We report the case of a patient who develops, after a massive ingestion of baclofen (supposed dose ingested: 1 200 mg), a hypotonic and calm coma, requiring her admission in our intensive care unit, and then a status epilepticus.

    We describe the case of a 50-year-old man with a fatal intoxication after accidental massive oral ingestion of manganese. The patient presented with lethargy, diffuse abdominal pain, vomiting, and profuse diarrhea after ingesting Epsom salts (magnesium sulfate heptahydrate) during a liver cleansing diet. Despite intensive care management with intubation, prone position ventilation, continuous venovenous hemofiltration, and multiple transfusions, he progressed to refractory shock with multiple organ dysfunction resulting in death within 72 h. Similar patients arrived at several hospitals with identical epidemiology (all had ingested the same salt obtained in the same place). Clinical and forensic investigations (X-ray diffraction) discovered that the supplier had mistakenly prepared the salts with hydrated manganese sulfate instead of magnesium sulfate heptahydrate. The results enabled the other patients to be successfully treated for hydrated manganese sulfate intoxication with life support in the intensive care unit and chelation therapy (EDTA). We describe the clinical presentation of acute manganese poisoning and alert professionals to the risk of an increasingly popular diet. This case demonstrates the importance of collaboration between clinicians, pathologists, and forensic scientists to resolve a difficult-to-diagnose case. Copyright © 2012 Elsevier Ireland Ltd.

  18. Transition between acute and chronic hepatotoxicity in mice is associated with impaired energy metabolism and induction of mitochondrial heme oxygenase-1.

    Directory of Open Access Journals (Sweden)

    Aniket Nikam

    Full Text Available The formation of protein inclusions is frequently associated with chronic metabolic diseases. In mice, short-term intoxication with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC leads to hepatocellular damage indicated by elevated serum liver enzyme activities, whereas only minor morphological changes are observed. Conversely, chronic administration of DDC for several weeks results in severe morphological damage, characterized by hepatocellular ballooning, disruption of the intermediate filament cytoskeleton, and formation of Mallory-Denk bodies consisting predominantly of misfolded keratins, Sqstm1/p62, and heat shock proteins. To evaluate the mechanistic underpinnings for this dichotomy we dissected the time-course of DDC intoxication for up to 10 weeks. We determined body weight change, serum liver enzyme activities, morphologic alterations, induction of antioxidant response (heme oxygenase-1, HO-1, oxidative damage and ATP content in livers as well as respiration, oxidative damage and the presence and activity of HO-1 in endoplasmic reticulum and mitochondria (mtHO-1. Elevated serum liver enzyme activity and oxidative liver damage were already present at early intoxication stages without further subsequent increase. After 2 weeks of intoxication, mice had transiently lost 9% of their body weight, liver ATP-content was reduced to 58% of controls, succinate-driven respiration was uncoupled from ATP-production and antioxidant response was associated with the appearance of catalytically active mtHO-1. Oxidative damage was associated with both acute and chronic DDC toxicity whereas the onset of chronic intoxication was specifically associated with mitochondrial dysfunction which was maximal after 2 weeks of intoxication. At this transition stage, adaptive responses involving mtHO-1 were induced, indirectly leading to improved respiration and preventing further drop of ATP levels. Our observations clearly demonstrate principally different

    Alcohol sales to intoxicated patrons are illegal and may lead to public health issues such as traffic crashes and violence. Over the past several decades, considerable effort has been made to reduce alcohol sales to underage persons but less attention has been given to the issue of sales to obviously intoxicated patrons. Studies have found a high likelihood of sales to obviously intoxicated patrons (i.e., overservice), but little is known about efforts by enforcement agencies to reduce these sales. We conducted a survey of statewide alcohol enforcement agencies and local law enforcement agencies across the US to assess their strategies for enforcing laws prohibiting alcohol sales to intoxicated patrons at licensed alcohol establishments. We randomly sampled 1,631 local agencies (1,082 participated), and surveyed all 49 statewide agencies that conduct alcohol enforcement. Sales to obviously intoxicated patrons were reported to be somewhat or very common in their jurisdiction by 55 % of local agencies and 90 % of state agencies. Twenty percent of local and 60 % of state agencies reported conducting enforcement efforts to reduce sales to obviously intoxicated patrons in the past year. Among these agencies, fewer than half used specific enforcement strategies on at least a monthly basis to prevent overservice of alcohol. Among local agencies, enforcement efforts were more common among agencies that had a full-time officer specifically assigned to carry out alcohol enforcement efforts. Enforcement of laws prohibiting alcohol sales to obviously intoxicated patrons is an underutilized strategy to reduce alcohol-related problems, especially among local law enforcement agencies.

    Body packers are persons who smuggle illegal drugs by swallowing condoms or plastic cylinders containing such substances. Body stuffers are drug dealers or drug abusers who swallow illegal drugs in an effort to conceal evidence during an arrest or in fear of being arrested. We report four cases and discuss management. Asymptomatic body packers may be managed conservatively with laxatives and water-soluble contrast medium. This method allows an accurate follow-up with abdominal radiography. If patients develop abdominal pain or signs and symptoms of intoxication, surgical intervention should be considered. Both types of patients should be monitored carefully.

  3. Population Analysis of Pharmacogenetic Polymorphisms Related to Acute Lymphoblastic Leukemia Drug Treatment

    Directory of Open Access Journals (Sweden)

    Marcela A. Chiabai

    2012-01-01

    Full Text Available This study aimed to evaluate in the Brazilian population, the genotypes and population frequencies of pharmacogenetic polymorphisms involved in the response to drugs used in treatment of acute lymphoblastic leukemia (ALL, and to compare the data with data from the HapMap populations. There was significant differentiation between most population pairs, but few associations between genetic ancestry and SNPs in the Brazilian population were observed. AMOVA analysis comparing the Brazilian population to all other populations retrieved from HapMap pointed to a genetic proximity with the European population. These associations point to preclusion of the use of genetic ancestry as a proxy for predicting drug response. In this way, any study aiming to correlate genotype with drug response in the Brazilian population should be based on pharmacogenetic SNP genotypes.

    2014-05-01

    Sodium nitrite (NaNO2) is a precursor to a variety of organic compounds (pharmaceuticals, dyes and pesticides), but it is best known as a food additive. The aim of the study is to investigate the influence of acute (i.p.) treatment of Wistar rats with NaNO2 (at the dose of 50 mg/kg b.w.) on the blood rheological properties and erythrocyte hematometric indices (Hb, HCT, RBC, MCV, RDW, MCH, MCHC). The significant differences were not found in the whole blood viscosity (WBV) values of the control and NaNO2-treated groups. The changes in the erythrocyte hematometric indices were statistically significant for RDW, MCHC and MCH at the 1st hour, five- and ten days after NaNO2 administration. Interestingly, at the day 5th of the NaNO2 treatment we obtained statistically significant lower values for the RBC count, Hb, HCT, RDW, as well as elevated indices MCV (no statistically significant), MCH, MCHC. The results obtained indicate that hemorheological and hematometric parameters examined should be monitored in cases of acute exposure to nitrites — for the purposes of clinical toxicology. The quantitative values of hematometric indices reported in our experimental model could be suitable for predicting NaNO2 intoxication and methemoglobinemia in animals and humans.

    Carbon monoxide (CO) intoxication is usually a serious condition, which can result in neurological disturbances or death. In some patients with CO intoxication, but not usually, a biphasic pattern can be seen. In this condition, after antitoxic treatment, patients may completely recover and after a short recovery period, neurological and/or psychiatric symptoms appear again. This condition is known as delayed encephalopathy and its occurrence rate is between 0.06% and 11.8%. Herein, we report a case with delayed encephalopathy after CO intoxication, which began with neurological symptoms and continued with obsessive-compulsive disorder, depression, kleptomania, and psychotic disorder. The 41-year-old female patient had no psychiatric or neurological symptoms or disorders prior to CO intoxication. Increased signal intensity changes in the basal region of the left temporal lobe (including the cortex and subcortical white matter), globus pallidus (bilateral), and cerebellar cortical and subcortical white matter (bilaterally symmetrical) was detected on axial T2-weighted magnetic resonance imaging (MRI). In addition, there were atrophic changes in both cerebellar hemispheres. To the best of our knowledge, this is the first case of kleptomania described after CO intoxication in the literature. We discuss the organic etiology of kleptomania and the other psychiatric symptoms of this patient in the light of recent research. We concluded that the kleptomania seen in this patient was related to concurrent lesions in the temporal lobe and globus pallidus; in other words, her kleptomania may have been related to dysfunction simultaneously seen in both the temporolimbic and frontal-subcortical circuits.

  7. Unpacking intoxication, racialising disability.

    Science.gov (United States)

    Chen, Mel Y

    2015-06-01

    This article examines concepts whose strictly medical applications have only partly informed their widespread use and suggests that demonstrably shared logics motivate our thinking across domains in the interest of a politically just engagement. It considers exchanges between the culturally complex concepts of 'toxicity' and 'intoxication', assessing the racialised conditions of their animation in several geopolitically--and quite radically--distinct scenarios. First, the article sets the framework through considering the racial implications of impairment and disability language of 'non-toxic' finance capital in the contemporary US financial crisis. Shifting material foci from 'illiquid financial bodies' to opiates while insisting that neither is 'more' metaphorically toxic than the other, the article turns to address the role of opium and temporality in the interanimations of race and disability in two sites of 19th-century British empire: Langdon Down's clinic for idiocy, and China's retort on opium to Queen Victoria. The article concludes with a provocation that suggests yet another crossing of borders, that between researcher and researched: 'intoxicated method' is a hypothetical mode of approach that refuses idealised research positions by 'critically disabling' the idealised cognitive and conceptual lens of analysis.

    Full Text Available Acute stenosing laryngotracheitis is the most common cause of the upper respiratory tract obstruction in children at the age of 6 months to 6 years old. It is the rapidly occurring syndrome, consisting of barking cough, hoarseness, stridor. The disease can be associated with development of respiratory failure and asphyxia, so pediatricians and emergency care doctors must be well aware of rational pharmacotherapy of this condition. The review contains the descriptions of the drugs, which efficacy is confirmed by convincing evidence database.

    Fasting has been recently discovered to improve overall health, but its beneficial effects in the presence of hepatic insufficiency have not been proven. The influence of fasting on the metabolism, immunological aspects, and oxidative stress of 40 male carbon tetrachloride (CCl4)-intoxicated Wistar rats was investigated in the present study. The rats were divided into four groups, including a placebo group, CCl4-intoxicated rats, which were injected subcutaneously with 1.0 ml/kg of CCl4 solution, a fasting group, which was fasted 12 h/day for 30 days, and a fourth group, which was injected with CCl4 and fasted. The metabolism, immunity, and oxidative stress improved in CCl4-intoxicated rats fasted for 12 h/day for 30 days, as evidenced in significant increase (p fasting improved metabolism, immunity, and oxidative stress in CCl4-intoxicated rats. Thus, fasting during Ramadan is safe for patients with hepatic disorders, as the prophet Mohammed (S) said "Keep the fast, keep your health". © The Author(s) 2014.

    A young man was sent to our emergency unit because he had suffered from vomiting and cold sweating for 2 days. At the time he was admitted, he had no acute abdominal pains or gastrointestinal symptoms, and a physical examination revealed nothing but a faster heart rate and moist, flushing skin. The patient had worked for 6 years at a plastic bottle-recycling factory, but none of his co-workers had the same symptoms. Nevertheless, because the plant also recycled pesticide bottles, we suspected organophosphate pesticide intoxication. The patient's plasma acetylcholinesterase level was checked, revealing 1498.6 microU/L (normal range: 2,000-5, 000) on the first day and 1,379 microU/L on the second day. Upon questioning, the patient recalled that one of his shoe soles had been damaged and that his foot had been wet from walking all day in rain collected on the factory floor on the day that his symptoms first occurred. We conducted a study in the change of preshift and postshift acetylcholinesterase levels among six of his co-workers on a rainy day. We used the Wilcoxon signed rank test to compare the preshift and postshift plasma acetylcholinesterase levels; no significant difference was revealed (p = 0.600), leaving contamination via the damaged shoe sole suspect. We reviewed the literature on organophosphate intoxication; pesticide bottle-recycling factories were reported to be at a low risk of organophosphate toxicity in the working environment. However, because the potential risk of intoxication is still present, protective equipment such as clothing, gloves, and water-proof shoes should be worn, and employees should be educated on the potential risks.

    The livers of two groups of rabbits exposed to longer lasting intoxidation, one with benzine vapors and the other one with ethyline vapors, were subjected to examination in an electron microscope twice; immediately after the completion of intoxication and then 3 months later. In both groups there were found: dilatation of the perinuclear spaces, a symptom of nucleolus segregation, dilation of the ergastoplasm, features of cristolysis of mitochondria and the absence of glycogen. These changes were more intensive in the animals intoxicated with ethyline. 3 months after the completion of the process of petrol intoxication the following was observed: persistence of the majority of the changes as well as accumulation of glycogen and hypertrophy of the smooth endoplasmatic reticulum. These changes were more intensified in animals intoxicated with ethyline.

    Full Text Available Acute intoxications in adolescents and adults are mostly associated with intentional or accidental ingestions. Intoxications are commonly seen in children aged between 1 and 5 years and most of the cases are associated with accidental intake. In most of the children, no clinical symptoms related to intoxication are observed or only mild effects can develop. The main route of drug elimination is through kidneys. Absolute clearance in children is often lower than in adults but weight-adjusted clearance is higher. Depending on more rapid elimination in children the plasma half-life of the drug might be shorter in children than in adults. A shorter elimination half-life means that plasma steady-state is achieved with repeated doses. It is important to prevent childhood intoxications, and the use of child-resistant packaging and adequate supervision together with the secure storage of household substances are the basis of prevention of accidental childhood intoxications. Intoxications represent one of the most common medical emergencies in children, and epidemiological characteristics vary in different countries. Therefore, special epidemiological surveillance is necessary for each country to determine the problem according to which preventive measures should be taken. Early awareness and taking appropriate therapeutic measures seems to be effective in the reduction of mortality rate. The major and most common non-pharmacological chemical intoxications in childhood have been reviewed here with the intent of helping health-care professionals, particularly pediatricians to recognize and reduce the risk of harmful childhood intoxications.

  17. Ammonia intoxication

    Data is presented which shows that there is a relation between ammonia concentration in the blood and state of consciousness. The concentrations of GTP and ATP also relate both to the ammonia concentration in blood and the state of consciousness. The rate of protein synthesis in the brain as measured by the percent of intracellular counts that are incorporated into protein is also related to ammonia concentration. These findings of energy depletion and depressed synthesis resulting from energy depletion suggest that the primary lesion in ammonia intoxication involves the Krebs cycle. The greater effect of ammonia on GTP than on ATP metabolism supports the view that the primary site of action of ammonia is at the glutamate dehydrogenase-ketoglutarate reduction step - and is consistent with previous work on this subject.

    The chick embryo chorioallantoic membrane (CAM) is a preclinical model widely used for vascular and anti-vascular effects of therapeutic agents in vivo. In this study, we examine the suitability of CAM as a predictive model for acute toxicology studies of drugs by comparing it to conventional mouse and rat models for 10 FDA-approved anticancer drugs (paclitaxel, carmustine, camptothecin, cyclophosphamide, vincristine, cisplatin, aloin, mitomycin C, actinomycin-D, melphalan). Suitable formulations for intravenous administration were determined before the average of median lethal dose (LD50) and median survival dose (SD(50)) in the CAM were measured and calculated for these drugs. The resultant ideal LD(50) values were correlated to those reported in the literature using Pearson's correlation test for both intravenous and intraperitoneal routes of injection in rodents. Our results showed moderate correlations (r(2)=0.42 - 0.68, PLD(50) values obtained using the CAM model with LD(50) values from mice and rats models for both intravenous and intraperitoneal administrations, suggesting that the chick embryo may be a suitable alternative model for acute drug toxicity screening before embarking on full toxicological investigations in rodents in development of anticancer drugs.

    1978-02-01

    Incorporation of /sup 55/Fe and of (/sup 14/C) glycine was studied in control embryos and mothers and in those which had received lead in the diet from day 7 of pregnancy. Incorporation of Fe into heme of embryonic liver which increases markedly for controls on day 17 of pregnancy was depressed greatly and showed no such increase in lead-intoxicated embryos. These embryos were retarded in growth but had normal heme concentrations in body and liver. Incorporation of glycine into embryonic heme and proteins was not affected. Data on incorporation in the mothers are also presented. It is thought that the impaired synthesis of heme in lead-intoxicated embryos limits their body growth during the late phase of pregnancy.

    Clinical symptoms and outcomes of uraemic patients ingesting star fruit are quite variable and may progress to death. The purpose of the present report was to discuss the neurotoxic effects of star fruit intoxication in uraemic patients and to present the efficacy of different therapeutic approaches. We studied a total of 32 uraemic patients who had ingested star fruit. Before the intoxication episodes, 20 patients were on regular haemodialysis, eight were on peritoneal dialysis and four were not yet undergoing dialysis. Two patients were analysed retrospectively from their charts, 17 were directly monitored by our clinic and 13 were referred by physicians from many areas throughout the country, allowing us to follow their outcome from a distance. Intoxicated patients were given different therapeutic approaches (haemodialysis, peritoneal dialysis and supportive treatment), and their outcomes were analysed. The most common symptoms were persistent and intractable hiccups in 30 patients (93.75%), vomiting in 22 (68.7%), variable degrees of disturbed consciousness (mental confusion, psychomotor agitation) in 21 (65.6%), decreased muscle power, limb numbness, paresis, insomnia and paresthesias in 13 (40.6%) and seizures in seven (21.8%). Patients who were promptly treated with haemodialysis, including those with severe intoxication, recovered without sequelae. Patients with severe intoxication who were not treated or treated with peritoneal dialysis did not survive. Haemodialysis, especially on a daily basis, is the ideal treatment for star fruit intoxication. In severe cases, continuous methods of replacement therapy may provide a superior initial procedure, since rebound effects are a common event. Peritoneal dialysis is of no use as a treatment, especially when consciousness disorders ensue.

  5. Acute poisoning with emamectin benzoate.

    Yen, Tzung-Hai; Lin, Ja-Liang

    2004-01-01

    Emamectin benzoate is the 4'-deoxy-4'-epi-methyl-amino benzoate salt of avermectin B1 (abamectin), which is similar structurally to natural fermentation products of Streptomyces avermitilis. Emamectin benzoate is being developed as a newer broad-spectrum insecticide for vegetables and has a very low application rate. The mechanism of action involves stimulation of high-affinity GABA receptors and a consequent increase in membrane chloride ion permeability. Animal studies indicate a wide margin of safety because mammalian species are much less sensitive due to lower GABA receptor affinities and relative impermeability of the blood-brain barrier. Notably, the literature has not reported human exposure resulting in toxicity. This paper describes a case of acute poisoning with Proclaim insecticide (Syngenta, Taiwan), consisting of 2.15% w/w emamectin benzoate in 2, 6-bis (1, 1-dimethylethyl)-4-methyl-phenol and 1-hexanol. The clinical manifestation was transient gastrointestinal upset with endoscopy-proven gastric erosion and superficial gastritis, mild central nervous system depression, and aspiration pneumonia. No specific antidote exists for emamectin benzoate intoxication; this patient was treated successfully with gastric lavage, administration of activated charcoal, and empiric antibiotics. Drugs that enhance GABA activity such as barbiturates and benzodiazepines were avoided.

    The purpose of the present study was to evaluate the toxicological aid and efficiency of preventive measures and methods in treatment of acute exogenous intoxications in hospitals in Tbilisi in 1990-2005. Structure of poisoning accidents in Tbilisi, its trends in last decade is analyzed and explained. The data were obtained in Georgian National Center for Disease Control and Medical statistics in Tbilisi. The study revealed that total number of hospitalizations due to acute poisoning in Tbilisi exceeded the number of hospitalizations due to acute myocardial infarction. In 1992-1994 Georgia was in severe social-economic crisis: the cases of acute poisoning increased and the number of hospitalizations had been reduced with concomitant longer hospital stay (in 1992--10.7 hospital days; in 1993-1994--13.7 hospital days), and higher mortality (in 1992--4%; in 1993--5.5%; 1994--5.2%). Low hospitalization rates in 1992-1994 should be explained by late patient referral to hospitals. Longer hospital stay was available due to free hospital care at that time. In 1995 with termination of free medical care number of hospitalized patients with acute intoxication raised annually; hospital stay shortened and mortality rate decreased. In 2003 mortality was reduced by 0.74% in Tbilisi. The prevalence of acute alcoholic intoxication incidence was noticed. Therefore hospital stay decreases. High prevalence of acute alcoholic intoxication was explained by the growth of alcohol consumption; lack of quality control of beverage production resulting in huge amount of unconditioned and counterfeit substances in the market, etc. As to poisonings due to medical substances 42% of cases were intoxications with anticonvulsants, sedative and psychotropic preparations; 17% with cardiovascular drugs; and 10% with narcotic substances. It was found, that poisoning incidence and their outcome significantly depend on social-economical conditions in Georgia. Measures to improve toxicology care in the

    The acute toxicity of cannabinoids is said to be low and there is little public awareness of the potentially hazardous cardiovascular effects of cannabis, e.g. marked increase in heart rate or supine blood pressure. We describe the cases of two young, putative healthy men who died unexpectedly under the acute influence of cannabinoids. To our knowledge, these are the first cases of suspected fatal cannabis intoxications where full postmortem investigations, including autopsy, toxicological, histological, immunohistochemical and genetical examinations, were carried out. The results of these examinations are presented. After exclusion of other causes of death we assume that the young men experienced fatal cardiovascular complications evoked by smoking cannabis.

    Generic drugs have been advocated to decrease the proportion of healthcare costs devoted to drugs, but are still underused. To assess citizens' preferences for brand name drugs (BNDs) compared with generic drugs for treating acute and chronic conditions. A questionnaire with eight hypothetical scenarios describing four acute and four chronic conditions was developed, with willingness to pay (WTP) determined using a payment card system randomized to ascending (AO) or descending order (DO) of prices. The questionnaire was distributed with an explanation sheet, an informed consent form and a pre-stamped envelope over a period of 3 weeks in 19 community pharmacies in Lausanne, Switzerland. The questionnaire was distributed to every third customer who also had health insurance, understood French and was aged ≥16 years (up to a maximum of ten customers per day and 100 per pharmacy). The main outcome measure was preferences assessed by WTP for BNDs as compared with generics, and impact of participants' characteristics on WTP. Of the 1800 questionnaires, 991 were distributed and 393 returned (pharmacy participation rate = 55%, subject participation rate = 40%, overall response rate = 22%); 51.7% were AO and 48.3% DO. Participants were predominantly women (62.6%) and of median age 62 years (range 16-90). The majority (70%) declared no WTP for BNDs as compared with generics. WTP was higher in people with an acute disease than in those with a chronic disease, did not depend on the type of chronic disease, and was higher in people from countries other than Switzerland. Most citizens visiting pharmacies attribute no added value to BNDs as compared with generics, although some citizen characteristics affected WTP. These results could be of interest to several categories of decision makers within the healthcare system.

  10. High-dose alcohol intoxication differentially modulates cognitive subprocesses involved in response inhibition.

    Aside from well-known physiological effects, high-dose alcohol intoxication (a.k.a. binge drinking) can lead to aversive social and legal consequences because response inhibition is usually compromised under the influence of alcohol. Although the behavioral aspects of this phenomenon were reported on extensively, the underlying neurophysiological mechanisms mediating this disinhibition are unclear. To close this gap, we used both behavioral and neurophysiological measures (event-related potentials, ERPs) to investigate which subprocesses of response inhibition are altered under the influence of high-dose alcohol intoxication. Using a within-subject design, we asked young healthy participants (n = 27) to complete a GO/NOGO task once sober and once intoxicated (approximately 1.2‰). During intoxication, high-dose alcohol effects were highest in a condition where the participants could not rely on automated stimulus-response mapping processes during response inhibition. In this context, the NOGO-P3 (ERP), that likely depends on dopaminergic signaling within mesocorticolimbic pathways and is thought to reflect motor inhibition and/or the evaluation of inhibitory processes, was altered in the intoxicated state. In contrast to this, the N2 component, which largely depends on nigrostriatal dopamine pathways and is thought to reflect inhibition on a pre-motor level, was not altered. Based on these results, we demonstrate that alcohol-induced changes of dopaminergic neurotransmission do not exert a global effect on response inhibition. Instead, changes are highly subprocess-specific and seem to mainly target mesocorticolimbic pathways that contribute to motor inhibition and the evaluation of such. © 2014 Society for the Study of Addiction.

  12. Cannabis use: a perspective in relation to the proposed UK drug-driving legislation.

    Science.gov (United States)

    Wolff, Kim; Johnston, Atholl

    2014-01-01

    With regard to THC (Δ(9)-tetrahydrocannabinol), the main psychoactive constituent identified in the plant Cannabis sativa L, several facts are indisputable. Cannabis remains the most commonly used drug in the UK among those who reported driving under the influence of illegal drugs in the previous 12 months. There is a significant dose-related decrement in driving performance following cannabis use; raised blood THC concentrations are significantly associated with increased traffic crash and death risk. When cannabis and alcohol are detected together, there is a greater risk to road safety than when either drug is used alone. Patterns of use are important when interpreting blood concentration data: Smoking infrequently a single cannabis cigarette leads to peak plasma THC concentrations (21-267 µg/L) causing acute intoxication. In habitual, daily users, plasma THC concentrations range from 1.0 to 11.0 µg/L and are maintained by sequestration of the drug from the tissues. These facts undoubtedly make setting thresholds for drug-driving legislation difficult but there is clearly a case for cannabis. Determining minimum blood THC concentrations at which a driver becomes sufficiently impaired to be unable to safely drive a vehicle is of particular concern given the increasing medicinal use of the drug. Internationally legislation for driving under the influence of drugs (DUID) is based on either a proof of impairment or a per se approach. For the latter this can be either zero-tolerance or based on concentration limits such as those used for alcohol. The different approaches are considered against current scientific evidence.

    Full Text Available Introduction and objectives: drug use is associated with multiple complications with an increase in morbidity, with death by acute drugs reactions (ADR being the most serious. A large percentage of the prison population has problems associated with drug additions, and substance abuse is also a common internal problem of penal institutions, despite their control measures. The goal of this study is to analyse the prevalence of ADR in penitentiaries, deceased sociodemographic characteristics as well as the circumstances in which they are produced. Material and methods: All deaths by ADR between 2001-2010 in Galicia are studied, in particular, those deaths that took place inside prisons. Results: In the whole sample (n=510 male (90.6%, single (46.1% with an average age of 35.8 and with a prevalent factor of long experience in drug abuse. Thirty seven of them died in Penal/Correctional Institutions, representing 7.3% of the total sample. The characteristics of this population subtype were similar to the total sample (average age: 34.7 years; 89.2% were males but we found significant differences regarding the substances detected. Discussion: ADR is the most frequent cause of death among drug addict convicts in prisons. The pattern of the detected substances in the toxicological analysis as well as the socio-demographic characteristics can help to establish a higher risk profile and preventive measures.

    Brief interventions encourage college students to eat more before drinking to prevent harm (Dimeff et al., 1999), although many women decrease their caloric intake (Giles et al., 2009) and the number of eating episodes (Luce et al., 2012) prior to drinking alcohol. Participants were 37 undergraduate women (24.3% Caucasian) who were recruited from a local bar district in the Midwest. This study examined whether changes in eating after intending to drink interacted with dietary restraint to predict accuracy of one's intoxication. Results indicated that changes in eating significantly moderated the relationship between dietary restraint and accuracy of one's intoxication level. After eating more food before intending to drink, women higher in restraint were more likely to overestimate their intoxication than women lower in restraint. There were no differences between women with high levels and low levels of dietary restraint in the accuracy of their intoxication after eating less food before intending to drink. Future research would benefit from examining interoceptive awareness as a possible mechanism involved in this relationship. Published by Elsevier Ltd.

    Drug abuse is a widespread problem affecting both teenagers and adults. Nitrous oxide is becoming increasingly popular as an inhalation drug, causing harmful neurological and hematological effects. Some gas chromatography-mass spectrometry (GC-MS) methods for nitrous oxide measurement have been previously described. The main drawbacks of these methods include a lack of sensitivity for forensic applications; including an inability to quantitatively determine the concentration of gas present. The following study provides a validated method using HS-GC-MS which incorporates hydrogen sulfide as a suitable internal standard allowing the quantification of nitrous oxide. Upon analysis, sample and internal standard have similar retention times and are eluted quickly from the molecular sieve 5Å PLOT capillary column and the Porabond Q column therefore providing rapid data collection whilst preserving well defined peaks. After validation, the method has been applied to a real case of N2O intoxication indicating concentrations in a mono-intoxication. Copyright © 2015 Elsevier B.V. All rights reserved.

    2013-06-01

    Renal failure secondary to acetaminophen poisoning is rare and occurs in approximately 1-2 % of patients with acetaminophen overdose. The pathophysiology is still being debated, and renal acetaminophen toxicity consists of acute tubular necrosis, without complication if treated promptly. Renal involvement can sometimes occur without prior liver disease, and early renal manifestations usually occur between the 2nd and 7th day after the acute acetaminophen poisoning. While therapy is exclusively symptomatic, sometimes serious metabolic complications can be observed. The monitoring of renal function should therefore be considered as an integral part of the management of children with acute, severe acetaminophen intoxication. We report 3 cases of adolescents who presented with acute renal failure as a result of voluntary drug intoxication with acetaminophen. One of these 3 girls developed severe renal injury without elevated hepatic transaminases.

    Moringa oleifera extract (Lam) has many antioxidant and protective properties. Objective: to investigate the antioxidant activities of Lam in counteracting the high oxidative stress caused by acute sub-lethal aluminium phosphide (AlP) intoxication in rat heart. These activities will be detected by histopathological examination and some oxidative stress biomarkers. a single sub-lethal dose of Alp (2 mg/kg body weight) was administered orally, and Lam was given orally at a dose (100 mg/kg body weight) one hour after receiving AlP to rats. aluminium phosphide caused significant cardiac histopathological changes with a significant increase in malondialdehyde (MDA); lipid peroxidation marker; and a significant depletion of antioxidant enzymes (catalase and glutathione reductase). However, treatment with Lam protected efficiently the cardiac tissue of intoxicated rats by increasing antioxidants levels with slight decreasing in MDA production compared to untreated group. This study suggested that Moringa oleifera extract could possibly restore the altered cardiac histopathology and some antioxidant power in AlP intoxicated rats, and it could even be used as adjuvant therapy against AlP-induced cardiotoxicity.

    Little is known about catatonia associated with lead intoxication. A retired printing house worker man presented with one week history of refusal to eat and mutism. He was treated with possible diagnosis of catatonia with administration of Lorazepam 3 mg P.O. daily. Significant improvement occurred after 48 hours. In further examinations, there was no evidence of physical and mental disorders while impairment in neuropsychiatry test, identification of Dohle body, basophilic stippling and toxic granulation in peripheral blood smear and blood lead level of 12.8 mug/dl were recorded. Possibly, lead intoxication results in changes in neurotransmitter system that leads to catatonia. Lorazepam improves patient's condition through changes in this system.

    Somatomedin activity was measured in 21 lead-intoxicated children to determine whether plumbism interferes with the processes of statural (bone) growth. Somatomedin activity was measured both by the rabbit coastal cartilage bioassay and by radioimmunoassay of somatomedin-C. Compared to values in normal children, both the bioassay and radioimmunoassay somatomedin activity was increased. The degree of body lead burden was so extensive that the 21 study children required chelation therapy. Following EDTA or BAL + EDTA chelation therapy, the overall somatomedin activity of these children with plumbism further increased significantly. In contrast, measures of body lead burden--including blood lead levels--decreased after treatment in all lead-intoxicated youngsters. We conclude that plumbism is associated with increased somatomedin activity. Hence the increased somatomedin activity may explain why clinical experience fails to find any long-term deleterious effect of saturnism on statural (bone) growth. Possible mechanisms underlying the increased somatomedin activity in the lead-intoxicated children remain to be defined

    Full Text Available Acute ethanol intoxication increases the production of reactive oxygen species (ROS. Hemorrhagic shock with subsequent resuscitation (H/R also induces ROS resulting in cellular and hepatic damage in vivo. We examined the role of acute ethanol intoxication upon oxidative stress and subsequent hepatic cell death after H/R. 14 h before H/R, rats were gavaged with single dose of ethanol or saline (5 g/kg, EtOH and ctrl; H/R_EtOH or H/R_ctrl, resp.. Then, rats were hemorrhaged to a mean arterial blood pressure of 30±2 mmHg for 60 min and resuscitated. Two control groups underwent surgical procedures without H/R (sham_ctrl and sham_EtOH, resp.. Liver tissues were harvested at 2, 24, and 72 h after resuscitation. EtOH-gavage induced histological picture of acute fatty liver. Hepatic oxidative (4-hydroxynonenal, 4-HNE and nitrosative (3-nitrotyrosine, 3-NT stress were significantly reduced in EtOH-gavaged rats compared to controls after H/R. Proapoptotic caspase-8 and Bax expressions were markedly diminished in EtOH-gavaged animals compared with controls 2 h after resuscitation. EtOH-gavage increased antiapoptotic Bcl-2 gene expression compared with controls 2 h after resuscitation. iNOS protein expression increased following H/R but was attenuated in EtOH-gavaged animals after H/R. Taken together, the data suggest that acute EtOH-gavage may attenuate H/R-induced oxidative stress thereby reducing cellular injury in rat liver.

Due to its serious adverse systemic effects, overdose must be recognized and treated. We report a case of an 18-year-old female who ingested 18 mg (~0.4 mg/kg of colchicine in a suicide attempt. The patient’s clinical manifestations included abdominal cramps, vomiting, pancytopenia, hypocholesterolemia, and rhabdomyolysis. Two unique manifestations of toxicity in this patient were profound and persistent, severe hypertriglyceridemia and electrolyte imbalance, mainly hypophosphatemia, with no other evident cause except the colchicine intoxication. Following intensive supportive treatment, including ventilator support, N-acetylcysteine, granulocyte colony stimulating factor, electrolyte repletion, and zinc supplementation, the patient made a complete recovery. Colchicine intoxication is a severe, life-threatening situation that should be followed closely in intensive care units. Severe changes in body functions can rapidly develop, as previously described in the literature. To our knowledge, this extremely elevated triglyceride level has never been reported without the administration of propofol, and requires further evaluation.

    Results. We have examined 80 children aged from 6 months to 3 years with acute obstructive bronchitis, and 40 age-matched children with acute nonobstructive bronchitis. The factors of high risk were determined and the mathematical model for predicting bronchial obstruction in acute bronchitis was created. Father’s age over 38 years, intrauterine growth restriction, maladjustment syndrome, early artificial feeding, genetic predisposition to atopy, passive smoking, fever in the postvaccination period, history of acute obstructive bronchitis and number of its episodes more than 2, paratrophia became prognostically significant. Fever up to 37.7 °C, mild intoxication syndrome up to 3 days, slow nasal breathing, IL-13 within 4.05–6.71 pg/ml and the relative number of lymphocytes expressing NF-kB less than 49.8 % were also associated with the development of bronchial obstruction in acute bronchitis.

  6. Mens Rea and Methamphetamine: High Time for a Modern Doctrine Acknowledging the Neuroscience of Addiction.

    2017-04-01

    In American criminal law, actus non facit reum, nisi mens sit rea, "an act does not make one guilty, without a guilty mind." Both actus reus and mens rea are required to justify criminal liability. The Model Penal Code's (MPC) section on culpability has been especially influential on mens rea analysis. An issue of increasing importance in this realm arises when an offensive act is committed while the actor is under the influence of drugs. Several legal doctrines address the effect of intoxication on mental state, including the MPC, limiting or eliminating its relevance to the mens rea analysis. Yet these doctrines do not differentiate between intoxication and addiction. Neuroscience research reveals that drug addiction results in catastrophic damage to the brain resulting in cognitive and behavioral deficits. Methamphetamine addiction is of particular interest to criminal law because it causes extensive neural destruction and is associated with impulsive behavior, violent crime, and psychosis. Furthermore, research has revealed important distinctions between the effects of acute intoxication and addiction. These findings have implications for the broader doctrine of mens rea and, specifically, the intoxication doctrines. This Note argues for the adoption of an addiction doctrine that acknowledges the effect of addiction on mens rea that is distinct from doctrines of intoxication.

    Four cases of attempts to smuggle narcotics (marijuana, heroin, and cocaine) by swallowing a large number of drug-filled foreign bodies (condoms and capsules) and hiding them from customs authorities in the gastrointestinal canal during transit are described. This is compared with a psychiatric patient who swallowed 48 Vicks Inhalers. Drug smuggling by swallowing condoms or capsules containing narcotics is now a worldwide ethical-legal problem. It also is of therapeutic and prognostic importance as this may lead to such emergencies as mechanical obstruction, rupture of the drug-containing foreign bodies, and life-threatening intoxication of the carrier.

Authors examined 93 patients stratified into three groups (acute poisoning with ethanol in patients with chronic alcoholism, without chronic alcoholism and those treated with reamberin). The presence of chronic alcoholism significantly augmented metabolic disturbances and influenced the disturbance of oxygen-transport function and free-radical processes in patients with acute intoxication with ethanol. Using of reamberin in the complex intensive therapy led to the decrease in metabolic disorders, which improved the clinical course of acute poisoning with ethanol in patients with chronic alcoholism.

    Lead is an important toxic metal found in industrial communities. Due to the industrialization in the recent decade in Thailand, lead intoxication as a toxicant-related disorder becomes a new public health problem. A retrospective study on clinical presentation of hospitalized patients with diagnosis of lead intoxication during year 1990-1999 in King Chulalongkorn Memorial hospital, the largest Thai Red Cross Society Hospital, was performed. All 14 cases diagnosed with lead intoxication were identified in our series. Average age of the subjects was 25.55 +/- 21.93 years old. Male predominance was detected in our series (male:female = 12:2). Two main groups of subjects as; (1) childhood aged below 10 years old (male:female = 4:2) and (2) adult aged between 24 and 60 years old (n = 8, all male), can be identified. For the first group, the clinical presentations were convulsion (n = 3), unexplained anemia (n = 1), attention deficit (n = 1) and asymptomatic (n = 1), respectively. All of the subjects in this group presented the history of living at the old battery plant area. Five of the six cases came from the same village. For the second group, the clinical presentations were unexplained abdominal pain (n = 5), chronic renal failure (n = 1), unexplained anemia (n = 1) and asymptomatic (n = 1), respectively. Most of the subjects (75%) in this group presented the history of working in the battery plant for more than 10 years. Another case presented the history of gunshot and residual bullet in the bone marrow. The other one left is an interesting case with the history of prolonged usage of ritual pill and holy paper incineration. Like other studies, battery plant had strong relation with the lead intoxication. Although the total identified cases are rather few, there may be more undetected asymptomatic lead intoxication cases in the community. Specific control of lead resulted from battery plant and monitoring of the workers as public health strategies are still

    Chronic and acute alcohol use are highly associated risk factors for suicides worldwide. Therefore, we examined suicide cases with and without alcohol use disorder (AUD) using data from the SNSF project "Suicide in Switzerland: A detailed national survey". Our investigations focus on correlations between acute and chronic alcohol use with reference to suicide and potential interactions with the methods of suicide. We used data from the SNSF project in which all cases of registered completed suicide in Switzerland reported to any of the seven Swiss institutes of legal and forensic medicine between 2000 and 2010 were collected. We extracted cases that were tested for blood alcohol to use in our analysis. We compared clinical characteristics, blood alcohol concentrations, and methods of suicide in cases with and without AUD. Out of 6497 cases, 2946 subjects were tested for acute alcohol use and included in our analysis. Of the latter, 366 (12.4%) persons had a medical history of AUD. Subjects with AUD significantly had higher blood alcohol concentrations and were more often in medical treatment before suicide. Drug intoxication as method of suicide was more frequent in cases with AUD compared to NAUD. Overall, we found a high incidence of acute alcohol use at the time of death in chronic alcohol misusers (AUD). The five methods of suicide most commonly used in Switzerland differed considerably between individuals with and without AUD. Blood alcohol concentrations varied across different methods of suicide independently from the medical history in both groups. Copyright © 2017 Elsevier B.V. All rights reserved.

    Nicotine intoxication is a rare cause of death and can lead to brain death after respiratory arrest and hypoxic-ischemic encephalopathy. To our knowledge, no previous reports regarding organ donation after nicotine intoxication have been described. We present a successful case of kidney donation after brain death caused by subcutaneous nicotine overdose from liquid nicotine from an e-cigarette cartridge in an attempted suicide. Both kidneys were transplanted successfully with immediate graft function, and both recipients were discharged at postoperative day 9 with normal plasma creatinine levels. Graft function has remained excellent in follow-up. This case suggests that kidneys from a donor with fatal nicotine intoxication may be successfully used for kidney transplantation in the absence of other contraindications for donation.

    Previous laboratory research on alcohol absorption has found that substitution of artificially sweetened alcohol mixers for sucrose-based mixers has a marked effect on the rate of gastric emptying, resulting in elevated blood alcohol concentrations. Studies conducted in natural drinking settings, such as bars, have indicated that caffeine ingestion while drinking is associated with higher levels of intoxication. To our knowledge, research has not examined the effects of alcohol mixers that contain both an artificial sweetener and caffeine, that is, diet cola. Therefore, we assessed the event-specific association between diet cola consumption and alcohol intoxication in bar patrons. We sought to determine whether putative increases in blood alcohol, produced by accelerated gastric emptying following diet cola consumption, as identified in the laboratory, also appear in a natural setting associated with impaired driving. We conducted a secondary analysis of data from 2 nighttime field studies that collected anonymous information from 413 randomly selected bar patrons in 2008 and 2010. Data sets were merged and recoded to distinguish between energy drink, regular cola, diet cola, and noncaffeinated alcohol mixers. Caffeinated alcohol mixers were consumed by 33.9% of the patrons. Cola-caffeinated mixed drinks were much more popular than those mixed with energy drinks. A large majority of regular cola-caffeinated mixed drink consumers were men (75%), whereas diet cola-caffeinated mixed drink consumers were more likely to be women (57%). After adjusting for the number of drinks consumed and other potential confounders, number of diet cola mixed drinks had a significant association with patron intoxication (β = 0.233, p 0.05). Caffeine's effect on intoxication may be most pronounced when mixers are artificially sweetened, that is, lack sucrose which slows the rate of gastric emptying of alcohol. Risks associated with on-premise drinking may be reduced by greater

    To determine age-related patterns of drug use initiation, drug sequencing and treatment entry among regular psychostimulant users. Cross-sectional study of 269 regular psychostimulant users, administered a structured interview examining onset of use for major licit and illicit drugs. The mean age at first intoxication was not associated with age or gender. In contrast, younger age was associated with earlier ages of onset for all of the illicit drug classes. Each additional year of age was associated with a 4 month increase in onset age for methamphetamine, and 3 months for heroin. By the age of 17, those born prior to 1961 had, on average, used only tobacco and alcohol, whereas those born between 1986 and 1990 had used nine different drug classes. The period between initial use and the transition to regular use, however, was stable. Age was also negatively correlated with both age at initial injection and regular injecting. Onset sequences, however, remained stable. Consistent with the age-related patterns of drug use, each additional year of age associated with a 0.47 year increase in the age at first treatment. While the age at first intoxication appeared stable, the trajectory through illicit drug use was substantially truncated. The data indicate that, at least among those who progress to regular illicit drug use, younger users are likely to be exposed to far broader polydrug use in their teens than has previously been the case. © 2012 Australasian Professional Society on Alcohol and other Drugs.

    The economic, social and health costs associated with alcohol and other drug use, including medicines, impact on the Australian community profoundly. Many Australians use alcohol and other drugs (AODs) on a regular basis and a significant number experience problems at some time. There are about 25,000 drug-related deaths annually, the majority of which are related to alcohol and tobacco use. Many young people die or are injured as a direct result of alcohol intoxication, accidental overdose and related problems, and significant numbers of elderly people are hospitalised, permanently incapacitated or suffer avoidable trauma through adverse drug reactions and side-effects of medications. It is estimated that at least 25 per cent of acute hospital beds hold patients with alcohol-related problems directly associated with the medical diagnosis, and there are comparable numbers of people needing social and other forms of assistance at some time. Despite the preventative nature of many AOD problems and the call for harm reduction, timely intervention and support for the thousands of Australians attending hospitals, community health and mental health services, nurses are yet to effectively assist the community in preventing and responding to the range of AOD problems. Nursing policy, guidelines and clinical expertise are required to assist the community in addressing this issue. Undergraduate, postgraduate and continuing education have a vital role to play in providing the profession with the knowledge, skills and research base to meet this challenge.

    Full Text Available Preclinical research documents that, aside from the primary and secondary reinforcing effects of nicotine intake itself, nicotine also acutely enhances the reinforcing efficacy of non-drug reinforcers (“rewards”. Study of these effects in humans has largely been overlooked, but very recent findings suggest they may have clinical implications for more fully understanding the persistence of tobacco dependence. This overview first outlines the topic and notes some recent human studies indirectly addressing nicotine effects on related responses (e.g., subjective ratings, explaining why those findings do not directly confirm enhancement of behavioral reinforcement per se due to nicotine. Then, the methodology used in the subsequently presented studies is described, demonstrating how those studies specifically did demonstrate enhancement of reinforced responding for non-drug rewards. The main section focuses on the limited controlled research to date directly assessing nicotine’s acute reinforcement-enhancing effects in humans, particularly as it relates to reinforced behavioral responding for non-drug rewards in non-human animal models. After detailing those few existing human studies, we address potential consequences of these effects for dependence and tobacco cessation efforts and then suggest directions for future research. This research indicates that nicotine per se increases responding in humans that is reinforced by some rewards (auditory stimuli via music, visual stimuli via video, but perhaps not by others (e.g., money. These reinforcement-enhancing effects in smokers are not due to dependence or withdrawal relief and can be restored by a small amount of nicotine (similar to a smoking lapse, including from e-cigarettes, a non-tobacco nicotine product. Future clinical research should examine factors determining which types of rewards are (or are not enhanced by nicotine, consequences of the loss of these nicotine effects after quitting

It was revealed that in lead intoxication degenerative disorders occur in all parts of the intervertebral disc of rats, affecting both the structure of the annulus fibrosus and the nucleus pulposus. At the same time degenerative changes of the annulus fibrosus can be expressed in disturbance of foliation, due to the appearance of cracks in plates and between them, banding of collagen fibers, reducing the density of fibrochondrocytes. In the nucleus pulposus fragmentation of syncytium structure occurs as well as disturbance of the interconnection between notochordal cells.

    Inorganic lead intoxication has emerged as an important and challenging clinical problem owing to increased awareness of lead and enhanced surveillance of exposed individuals. However, recognition may not be very difficult when there is an obvious history of exposure. Our interest began a few years ago when we could trace an outbreak, following a patient who was admitted with colickly abdominal pain, convulsions, and coma. After that, 16 more cases were identified and characterized. All patients recovered completely after adequate chelation therapy. Although the clinical picture of lead intoxication is pleomorphic, the increased awareness of gastroenterologists in this subject may possibly bring chronically complaining difficult patients to an earlier, unexpected, and fairly treatable disease.

    1981-01-01

    Four cases of attempts to smuggle narcotics (marijuana, heroin, and cocaine) by swallowing a large number of drug-filled foreign bodies (condoms and capsules) and hiding them from customs authorities in the gastrointestinal canal during transit are described. This is compared with a psychiatric patient who swallowed 48 Vicks Inhalers. Drug smuggling by swallowing condoms or capsules containing narcotics is now a worldwide ethical-legal problem. It also is of therapeutic and prognostic importance as this may lead to such emergencies as mechanical obstruction, rupture of the drug-containing foreign bodies, and life-threatening intoxication of the carrier.

    Full Text Available BACKGROUND - Synthetic cannabinoids in smoking mixtures (such as Spice or as raw powder are sold for recreational use as an alternative to herbal cannabis (hashish and marijuana. Although clinical case studies have documented an array of side effects, there is also information available at Internet based drug discussion forums. AIM - Our study investigates experiences of side effects from use of synthetic cannabinoids, as described and anonymously shared on Swedish online discussion forums. METHODS - A systematic search yielded 254 unique and publicly available self-reports from the Swedish forum flashback.org. These texts were analysed thematically, which resulted in 32 sub-themes, which were combined into three overarching themes. RESULTS & CONCLUSION - The experiences of negative side effects were described as (1 Adverse reactions during acute intoxication; (2 Hangover the day after intoxication; (3 Dependency and withdrawal after long-term use. The first theme was characterized by an array of fierce and unpredictable side effects as tachycardia, anxiety, fear and nausea. The acute intoxication reactions were congruent with the side effects published in clinical case studies. The day after intoxication included residual effects of dullness, apathy, nausea and headache. Long-term use resulted in dependency and experiences of being emotionally numb and disconnected. Furthermore, withdrawal was described as sweating, shaking, loss of appetite and insomnia. Both the hangover and the long-term effects have previously been given little scientific attention and need to be investigated further. Drug related Internet discussion forums constitute an overlooked source of information which can aid in the identification of previously unknown risks and effects

    Interleukin (IL)-38, a member of the IL-1 family, shows high homology to IL-1 receptor antagonist (IL-1Ra) and IL-36 receptor antagonist (IL-36Ra). Its function in interstitial lung disease (ILD) is still unknown. To determine the expression pattern of IL-38 mRNA, a panel of cDNAs derived from various tissues was analyzed by quantitative real-time PCR. Immunohistochemical reactivity with anti-human IL-38 monoclonal antibody (clone H127C) was evaluated semi-quantitatively in lung tissue samples from 12 patients with idiopathic pulmonary fibrosis/usual interstitial pneumonia (IPF/UIP), 5 with acute exacerbation of IPF, and 10 with anticancer drug-induced ILD (bleomycin in 5 and epidermal growth factor receptor-tyrosine kinase inhibitor in 5). Control lung tissues were obtained from areas of normal lung in 22 lung cancer patients who underwent extirpation surgery. IL-38 transcripts were strongly expressed in the lung, spleen, synoviocytes, and peripheral blood mononuclear cells, and at a lower level in pancreas and muscle. IL-38 protein was not strongly expressed in normal pulmonary alveolar tissues in all 22 control lungs. In contrast, IL-38 was overexpressed in the lungs of 4 of 5 (80%) patients with acute IPF exacerbation and 100% (10/10) of the patients with drug-induced ILD. IL-38 overexpression was limited to hyperplastic type II pneumocytes, which are considered to reflect regenerative change following diffuse alveolar damage in ILD. IL-38 may play an important role in acute and/or chronic inflammation in anticancer drug-induced lung injury and acute exacerbation of IPF. Copyright © 2017 The Japanese Respiratory Society.

  15. Acute drug treatment in the early C. elegans embryo.

    Directory of Open Access Journals (Sweden)

    Ana Carvalho

    Full Text Available Genetic and genome-wide RNAi approaches available in C. elegans, combined with tools for visualizing subcellular events with high-resolution, have led to increasing adoption of the early C. elegans embryo as a model for mechanistic and functional genomic analysis of cellular processes. However, a limitation of this system has been the impermeability of the embryo eggshell, which has prevented the routine use of small molecule inhibitors. Here, we present a method to permeabilize and immobilize embryos for acute inhibitor treatment in conjunction with live imaging. To identify a means to permeabilize the eggshell, we used a dye uptake assay to screen a set of 310 candidate genes defined by a combination of bioinformatic criteria. This screen identified 20 genes whose inhibition resulted in >75% eggshell permeability, and 3 that permeabilized embryos with minimal deleterious effects on embryo production and early embryonic development. To mount permeabilized embryos for acute drug addition in conjunction with live imaging, we combined optimized inhibition of one of these genes with the use of a microfabricated chamber that we designed. We demonstrate that these two developments enable the temporally controlled introduction of inhibitors for mechanistic studies. This method should also open new avenues of investigation by allowing profiling and specificity-testing of inhibitors through comparison with genome-wide phenotypic datasets.

    The web-based open sale of unregulated new psychoactive substances (NPS) has shown a steady increase in recent years. Analysis of drug products sold as NPS is useful to confirm the true chemical contents, for comparison with the substances detected in corresponding body fluids, but also to study drug trends. This work describes the examination of 251 drug products that were randomly submitted for analysis in 173 cases of suspected NPS-related intoxications in the Swedish STRIDA project in 2010-2015. Of the products, 39% were powders/crystals, 32% tablets/capsules, 16% herbal materials, 8% liquids, 1% blotters, and 4% others. The analysis involved tandem mass spectrometry and nuclear magnetic resonance spectroscopy. In 88 products (35%), classic psychoactive substances, prescription pharmaceuticals, dietary supplements, or doping agents were found; however, in none of these cases had an NPS-related intoxication been indicated from product markings or patient self-reports. Another 12 products tested negative for psychoactive substances. The remaining 151 products contained 86 different NPS (30% contained ≥2 substances). In 104 drug products, a specific NPS ingredient was indicated based on labelling (69%) or patient self-report; in 92 cases this was also analytically confirmed to be correct. Overall, the NPS products submitted for analysis in the STRIDA project showed a high degree of consistency between suspected and actual content (88%). The results of related urine and/or blood analysis further demonstrated that the patients commonly (89%) tested positive for the indicated NPS, but also revealed that polysubstance intoxication was common (83%), indicating use of additional drug products.

    Preventing alcohol-related harm in drinking environments is a growing international priority. Factors relating to the physical, social and staffing environments in bars can contribute to increased alcohol consumption and harm. Understanding the relationships between such factors and intoxication in European drinking environments is critical to developing appropriate interventions. We undertook a quantitative observational study in 60 bars in four European cities, in The Netherlands, Slovenia, Spain and the UK (n = 237 observational visits). Using a structured observational schedule, researchers recorded characteristics of the bar environment and rated customer intoxication levels. All physical bar characteristics showed associations with intoxication before interactions between them were controlled for. Hierarchical modelling found significant independent associations between intoxication and use of plastic glassware, promotion of non-alcoholic drinks (often energy drinks), permissive environments, poor washroom facilities, the presence of a dance floor, customer sexual activity/competitiveness and later observational time. Findings suggest that prevention efforts should focus on raising and enforcing managerial standards in bars. While harm reduction measures such as plastic glassware are often promoted for high risk bars, such measures are inadequate to address public health concerns and insufficient to demonstrate social responsibility.

    The efficacy and tolerability of nimesulide, a non-steroidal anti-inflammatory drug (NSAID) 100 mg twice daily were compared with diclofenac 75 mg b.i.d. in short term treatment of acute shoulder (acute subdeltoid bursitis and bicipital tendinitis) in adult patients. In this double-blind (double-dummy), randomised, parallel group study over two weeks, 122 patients were included. The Mann-Whitney statistics revealed therapeutic equivalence of both treatments with a slight superiority for nimesulide. The tolerability of nimesulide, judged by investigators and patients and analysed statistically, was superior to that of diclofenac. Thus, the benefit-risk relationship was better for the test drug than for the reference drug.

    Disturbance of cochlear microcirculation is considered to be the final common pathway of various inner ear diseases. Hyperfibrinogenemia causing increased plasma viscosity is a known risk factor for sudden sensorineural hearing loss and may lead to a critical reduction of cochlear blood flow. The aim of this study was to evaluate the effect of a substantial reduction of plasma fibrinogen levels by drug-induced defibrinogenation for the treatment of acute hearing loss in vivo. Acute hearing loss was induced by hyperfibrinogenemia (i.v. injection of 330 mg/kg BW fibrinogen), using a guinea pig animal model. Parameters of cochlear microcirculation and hearing thresholds were quantified by intravital microscopy and evoked response audiometry. After obtaining baseline values, the course of hearing loss and disturbances of microcirculation were investigated under influence of intravenous defibrinogenation therapy (ancrod), corticosteroid, or placebo treatment, using 5 animals/group. Acute hyperfibrinogenemia caused hearing loss from 10 ± 7 to 26 ± 10 dB SPL at baseline. Drug-induced reduction of fibrinogen levels showed a significant increase of cochlear microcirculation (1.6-fold) and recovered hearing threshold (11 ± 6 dB SPL). Placebo or corticosteroid treatment had no effect on hearing loss (35 ± 7 dB SPL and 32 ± 18 dB SPL, respectively). Acute hyperfibrinogenemia resulted in hearing loss. Drug-induced reduction of elevated fibrinogen levels caused an increase in cochlear blood flow and a decrease in hearing thresholds. Placebo or corticosteroid treatment had no effect. Reduction of plasma fibrinogen levels could serve as a clinical treatment option for acute hearing loss.

    Several soil ingestion studies have indicated that some children ingest substantial amounts of soil on given days. Although the EPA has assumed that 95% of children ingest 200 mg soil/day or less for exposure assessment purposes, some children have been observed to ingest up to 25-60 g soil during a single day. In light of the potential for children to ingest such large amounts of soil, an assessment was made of the possibility for soil pica episodes to result in acute intoxication from conta...

    This experiment examined relationships among adulthood victimization, sexual assertiveness, alcohol intoxication, and sexual risk-taking in female social drinkers (N=161). Women completed measures of sexual assault and intimate partner violence history and sexual assertiveness before random assignment to 1 of 4 beverage conditions: control, placebo, low dose (.04%), or high dose (.08%). After drinking, women read a second-person story involving a sexual encounter with a new partner. As protagonist of the story, each woman rated her likelihood of condom insistence and unprotected sex. Victimization history and self-reported sexual assertiveness were negatively related. The less sexually assertive a woman was, the less she intended to insist on condom use, regardless of intoxication. By reducing the perceived health consequences of unprotected sex, intoxication indirectly decreased condom insistence and increased unprotected sex. Findings extend previous work by elucidating possible mechanisms of the relationship between alcohol and unprotected sex - perceived health consequences and situational condom insistence - and support the value of sexual assertiveness training to enhance condom insistence, especially since the latter relationship was robust to intoxication.

    Introduction. As blood concentration measurement of commonly abused alcohol is readily available, the equation was proposed in previous publication to predict the change of their concentration. The change of ethylene glycol (EG) concentrations was studied in a case of intoxication to estimate required time for hemodialysis (HD) using linear regression. Case Report. A 55-year-old female with past medical history of seizure disorder, bipolar disorder, and chronic pain was admitted due to severe agitation. The patient was noted to have metabolic acidosis with elevated anion gap and acute kidney injury, which prompted blood concentration measurement of commonly abused alcohol. Her initial EG concentration was 26.45 mmol/L. Fomepizole therapy was initiated, soon followed by HD to enhance clearance. Discussion. Plotting of natural logarithm of EG concentrations over time showed that EG elimination follows first-order kinetics and predicts the change of its concentration well. Pharmacokinetic review revealed minimal elimination of EG by alcohol dehydrogenase (ADH) which could be related to genetic predisposition for ADH activity and home medications as well as presence of propylene glycol. Pharmacokinetics of EG is relatively well studied with published parameters. Consideration and application of pharmacokinetics could assist in management of EG intoxication including HD planning.

    The benzodiazepine/GABA (gammaaminobutyric acid) receptor complex was investigated during severe ethanol intoxication and withdrawal in the rat. The intragastric intubation technique was used to establish physical ethanol dependence in the animals. Cerebral cortex from male Wistar rats was studied 1) after 31/2 days of severe ethanol intoxication, 2) during the ethanol withdrawal reaction and 3) in a control group. The effect of GABA-ergic activation by muscimol and THIP (4,5,6,7-tetrahydroisoxazole(5,4-c)pyridin-3-01) on 3 H-diazepam binding was unchanged during ethanol intoxication and withdrawal, as was the affinity constant (Ksub(D)) and the maximal number of binding sites (Bsub(max)) for 3 H-flunitrazepam. In conclusion, the benzodiazepine/GABA receptor complex is unlikely to play any causual part in physical ethanol dependence. (author)

    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy. © 2014 Elsevier B.V.

    Accidental and intended Ricinus communis intoxications in humans and animals have been known for centuries but the causative agent remained elusive until 1888 when Stillmark attributed the toxicity to the lectin ricin. Ricinus communis is grown worldwide on an industrial scale for the production of castor oil. As by-product in castor oil production ricin is mass produced above 1 million tons per year. On the basis of its availability, toxicity, ease of preparation and the current lack of medical countermeasures, ricin has gained attention as potential biological warfare agent. The seeds also contain the less toxic, but highly homologous Ricinus communis agglutinin and the alkaloid ricinine, and especially the latter can be used to track intoxications. After oil extraction and detoxification, the defatted press cake is used as organic fertilizer and as low-value feed. In this context there have been sporadic reports from different countries describing animal intoxications after uptake of obviously insufficiently detoxified fertilizer. Observations in Germany over several years, however, have led us to speculate that the detoxification process is not always performed thoroughly and controlled, calling for international regulations which clearly state a ricin threshold in fertilizer. In this review we summarize knowledge on intended and unintended poisoning with ricin or castor seeds both in humans and animals, with a particular emphasis on intoxications due to improperly detoxified castor bean meal and forensic analysis.

    1984-01-01

    Dietary levels of 0.6 to 0.8% magnesium in a corn-soy basal were rachitogenic. These rickets appeared most like phosphorus deficiency. Bone Ca/P ratios were numerically quite low implying a lack of transformation from amorphous calcium phosphate to hydroxyapatite. Bone alkaline phosphatase activity was elevated. Additional dietary phosphorus ameliorated, but could not overcome the rachitogenic effects of magnesium. Tibial dyschondroplasia (TD), induced by elevated dietary P, was decreased by high levels of dietary Mg, but with no decrease in plasma phosphorus. Anticoccidial ionophores fed in conjunction with a moderate dietary challenge of Mg (0.48%) produced no clear changes in plasma calcium or Mg, but did interact to reduce body weight. The diarrhea caused by magnesium intoxication is not due to hyperosmotic loads of Mg per se. Rather, Cl was observed to be the major ionic constituent of the gut osmotic load implying different gut ionic fluxes in control versus magnesium intoxicated chicks. These data imply that the cathartic action of Mg is due to hypersecretion of the gut. Effects mediated or modified by the CNS changed in magnesium intoxicated chicks. Such chicks appeared cold and stayed near the heat. When startled, they exhibited extreme avoidance behavior and seizures similar to epilepsy and/or Cl deficiency. Brain tissue Mg content did not concomitantly increase. Whether these effects are due to central signals is unclear.

    Yellow phosphorus is a toxic substance used in the production of firework cracker, fireworks, ammunition and agricultural dung. When ingested, it shows its effects mainly in the liver, the kidneys, and the brain. A four-year-old girl had died as a result of acute hepatic failure caused by ingesting a firework cracker. The case showed high levels of hepatic enzymes, along with non-specific signs such as nausea, vomiting and diarrhea. Autopsy revealed diffuse microvesicular steatosis in the liver and disseminated degeneration in the proximal tubules of the kidneys. In cases with concomitant hepatorenal failure and cardiovascular collapse, death is inevitable. However, when only hepatic failure develops, hepatic transplantation may be lifesaving. Although intoxication from ingesting yellow phosphorus has a very high rate of mortality, forensic cases are extremely rare in the literature.

    Full Text Available Abstract Background Methylene bis(thiocyanate (MBT is a microbiocidal agent mainly used in industrial water cooling systems and paper mills as an inhibitor of algae, fungi, and bacteria. Case presentation We describe the first case of severe intoxication following inhalation of powder in an industrial worker. Profound cyanosis and respiratory failure caused by severe methemoglobinemia developed within several minutes. Despite immediate admission to the intensive care unit, where mechanical ventilation and hemodialysis for toxin elimination were initiated, multi-organ failure involving liver, kidneys, and lungs developed. While liver failure was leading, the patient was successfully treated with the MARS (molecular adsorbent recirculating system procedure. Conclusion Intoxication with MBT is a potentially life-threatening intoxication causing severe methemoglobinemia and multi-organ failure. Extracorporeal liver albumin dialysis (MARS appears to be an effective treatment to allow recovery of hepatic function.

    Full Text Available Objective: The aim of the study is to analyze the general aspects of cases with carbon monoxide intoxication in order to improve the approach to future patients. Material and Methods: The hospital records of 84 children (mean age 4.71±2.64 years; 48 male, 36 female who had been admitted to Paediatric Emergency Department for carbon monoxide intoxication between October 2007 and February 2009, were retrospectively evaluated in a descriptive analysis.Results: The source of carbon monoxide intoxication was heaters, waterheaters and fi re in 82.1%, 7.1% and 6% of cases, respectively. There was a statistically signifi cant difference between the carboxyhemoglobin levels of the patients according to the clinical classifi cation (p<0.05. The intoxication caused by heaters was observed signifi cantly in November, December and January (p<0.001, between 16:00-24:00 hours (p<0.001 and among more than one member of a family (p<0.001. A medium level correlation was detected between the treatment approach and clinical classifi cation (r=0.50, p<0.001. Conclusion: Carbon monoxide intoxication, in the presented series, was found to develop accidentally; mostly in the Winter season; during night hours when the family members gathered together. The carboxyhemoglobin levels were appropriate with the developing clinical findings. Carboxyhemoglobin level solely was not enough for achieving the diagnosis and planning the treatment.

    The risk assessment of residues of veterinary drugs in food is a field that continues to evolve. The toxicological end-points to be considered are becoming more nuanced and in light of growing concern about the development of antimicrobial resistance, detailed analysis of the antimicrobial activity of the residues of veterinary drugs in food is increasingly incorporated in the assessment. In recent years, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has refined its approaches to provide a more comprehensive and fit-for-purpose risk assessment. This publication describes in detail the consideration of acute and chronic effects, the estimation of acute and chronic dietary exposure, current approaches for including microbiological endpoints in the risk assessment, and JECFA's considerations for the potential effects of food processing on residues from veterinary drugs. JECFA now applies these approaches in the development of health-based guidance values (i.e. safe exposure levels) for residues of veterinary drugs. JECFA, thus, comprehensively addresses acute and chronic risks by using corresponding estimates for acute and chronic exposure and suitable correction for the limited bioavailability of bound residues by the Gallo-Torres model. On a case-by-case basis, JECFA also considers degradation products that occur from normal food processing of food containing veterinary drug residues. These approaches will continue to be refined to ensure the most scientifically sound basis for the establishment of health-based guidance values for veterinary drug residues.

    Though a majority of cases of lead intoxication come from occupational exposures, traditional and folk remedies have also been reported to contain toxic amounts of lead. We present a large series of patients with lead poisoning due to intake of Ayurvedic medicines, all of whom presented with unexplained abdominal pain. This was a retrospective, observational case series from a tertiary care center in India. The charts of patients who underwent blood lead level (BLL) testing as a part of workup for unexplained abdominal pain between 2005 and 2013 were reviewed. The patients with lead intoxication (BLLs >25 μg/dl) were identified and demographics, history, possible risk factors, clinical presentation and investigations were reviewed. Treatment details, duration, time to symptomatic recovery, laboratory follow-up and adverse events during therapy were recorded. BLLs were tested in 786 patients with unexplained abdominal pain and high levels were identified in 75 (9.5%) patients, of which a majority (73 patients, 9.3%) had history of Ayurvedic medication intake and only two had occupational exposure. Five randomly chosen Ayurvedic medications were analyzed and lead levels were impermissibly high (14-34,950 ppm) in all of them. Besides pain in abdomen, other presenting complaints were constipation, hypertension, neurological symptoms and acute kidney injury. Anemia and abnormal liver biochemical tests were observed in all the 73 patients. Discontinuing the Ayurvedic medicines and chelation with d-penicillamine led to improvement in symptoms and reduction in BLLs in all patients within 3-4 months. The patients presenting with severe recurrent abdominal pain, anemia and history of use of Ayurvedic medicines should be evaluated for lead toxicity. Early diagnosis in such cases can prevent unnecessary investigations and interventions, and permits early commencement of the treatment.

    Full Text Available Cadmium (Cd is a well-known nephrotoxic agent. Cd-induced renal dysfunction has been considered as one of the causes leading to the development of hypertension. The correlation between Cd concentration in blood and urine and cardiovascular diseases has been discussed in many epidemiological studies. A therapy with chelating agents is utilized for the treatment of toxic metal intoxication. Herein we present novel information indicating that monensin (applied as tetraethylammonium salt is a promising chelating agent for the treatment of Cd-induced renal and cardiac dysfunction. The study was performed using the ICR mouse model. Adult ICR male mice were divided into three groups with six animals in each group: control (received distilled water and food ad libitum for 28 days; Cd-intoxicated (treated orally with 20 mg/kg b.w. Cd(II acetate from day 1 to day 14 of the experimental protocol, and monensin treated group (intoxicated with Cd(II acetate as described for the Cd-intoxicated group followed by oral treatment with 16 mg/kg b.w. tetraethylammonium salt of monensic acid for 2 weeks. Cd intoxication of the animals resulted in an increase of the organ weight/body weight indexes. Cd elevated significantly creatinine and glucose level in serum. Monensin treatment improved the organ weight/body weight ratios. The therapy of the Cd-intoxicated animals with monensin ameliorated the creatinine and glucose level in serum and decreased the concentration of the toxic metal ions in the heart and kidneys by 54 % and 64 %, respectively
