    Thinners, including aromatic hydrocarbons such as toluene, xylene, and N-hexane, are widely used in industry for the production of plastics, varnish, paint, and glue. Use of these toxic agents frequently leads to chronic intoxication caused by abuse or misuse of solvents, which are usually taken in through inhalation. Thinners may have neurotoxic, myotoxic, hepatotoxic, nephrotoxic, and cardiotoxic systemic effects. The patient described in this report attempted to commit suicide by injecting 10 cc thinner into the left hemithorax. Acute chemical empyema developed at the left hemithorax. No bacterial growth was noted in empyema liquid and blood samples. Empyema was treated with tube thoracostomy, and full remission was observed after 33 d. No systemic toxic signs were noted, other than a low level of hepatotoxicity. Although pleural effusion, atelectasis, and pleural thickening were observed at the acute phase on computed tomography (CT) of the thorax, only pleural thickening persisted on CT of the thorax after 1 y. Investigators could not find a documented case of parenteral use of thinners in the medical literature.

    In this study, we evaluated the acute clinical and para-clinical abnormalities arising from paint thinner (PT) poisoning in children. Data were collected from 2008 to 2013, and sourced from the medical records of PT-intoxicated children and through questionnaires. A total of 42 children were enrolled in the study. The mean age was 37.2±2.4 months. The participants ranged from10 to 96 months of age; with a median age of 3 months; and a modal age of 24 months. The sex ratio in the study was 22 males (64.9%) to 20 females (35.1%). Clinical biochemistry results of participants revealed the significant presence of alkaline phosphatase (ALP, 569.25±151.58U/L), and lactate dehydrogenase (LDH, 576.14±164.97 IU/L). Arterial blood gas (ABG) analysis was also carried out. Chest X-ray predominantly revealed right side alveolar air space consolidation. These results confirmed hepatotoxicity and pneumonia in PT-intoxicated children. The study also revealed that positive outcomes were achieved in patients with early treatment and management. In addition, the current finding confirmed the timely transfer of the victim to the poisoning center.

    We report six cases of chronic manganese intoxication in workers at a ferromanganese factory in Taiwan. Diagnosis was confirmed by assessing increased manganese concentrations in the blood, scalp, and pubic hair. In addition, increased manganese levels in the environmental air were established. The patients showed a bradykinetic-rigid syndrome indistinguishable from Parkinson's disease that responded to treatment with levodopa.

    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.

Chronic impact of sodium tetraborate on an organism resulted into increase in the relative weight of a spleen in comparison with body weight that led to increase in weight coefficient of a spleen. Increase in the relative area of all functional zones (periarterial zone, the germinal center, mantle and marginal zones) of lymphoid slug of a white pulp is established. Decrease of an index a red/white pulp, as a result of increase of the area of a white pulp in response to chronic intoxication of an organism is revealed. During the after intoxication period as a result of decrease in immune tension there occured decrease of body weight and decrease in the area of a white pulp. During this period there was a reliable decrease of the area of lymphoid slug and decrease in the area of its functional zones (a periarterial zone, the center of manifolding, mantle and marginal zones).

    Volatile substances are used widespread, especially among young people, as a cheap and easily accessible drug. Tetrachloroethylene is one of the solvents exerting effects on the central nervous system with experiences of disinhibition and euphoria. The case presented is that of a 27-year-old female, found dead by her father at home with cotton swabs dipped in the nostrils. She was already known for this type of abuse and previously admitted twice to the hospital for nonfatal acute poisonings. The swabs were still soaked in tetrachloroethylene. Toxicological and histological investigations demonstrated the presence of an overlap between chronic intake of the substance (with high concentrations in sites of accumulation, e.g., the adipose tissue, and contemporary tissue damage, as histologically highlighted) and acute intoxication as final cause of death, with a concentration of 158 mg/L in cardiac blood and 4915 mg/kg in the adipose tissue. No other drugs or medicines were detected in body fluids or tissues, and to our knowledge, this is the highest concentration ever detected in forensic cases. This peculiar case confirms the toxicity of this substance and focuses on the importance of complete histological and toxicological investigations in the distinction between chronic abuse and acute intoxication.

    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.

    A case of optic neuropathy induced by thinner sniffing is reported. A 17-year-old girl, who had been sniffing a lacquer thinner for three months, suffered acute blindness followed by optic atrophy. Brain computed tomography revealed symmetrical low attenuation areas in the bilateral putamen. An analysis of the thinner by gas chromatography showed that its major components in a vaporized state were methyl alcohol and metyhl acetate. The optic neuropathy was induced by these solvents. In the diagnosis of the intoxication of mixed organic solvents, the measurement of each solvent in its vapor phase is considered to be quite important.

    To document the biochemical and pathologic features of vitamin D intoxication in lynx and to characterize mineral metabolism in healthy lynx, blood samples were obtained from 40 captive lynx that had been receiving excessive (approximately 30 times the recommended dose) vitamin D3 in the diet, and from 29 healthy free ranging lynx. Tissue samples (kidney, stomach, lung, heart and aorta) were collected from 13 captive lynx that died as a result of renal disease and from 3 controls. Vitamin D intoxication resulted in renal failure in most lynx (n = 28), and widespread extraskeletal calcification was most severe in the kidneys and less prominent in cardiovascular tissues. Blood minerals and calciotropic hormones in healthy lynx were similar to values reported in domestic cats except for calcitriol which was higher in healthy lynx. Changes in mineral metabolism after vitamin D intoxication included hypercalcemia (12.0 ± 0.3 mg/dL), hyperphosphatemia (6.3 ± 0.4 mg/dL), increased plasma calcidiol (381.5 ± 28.2 ng/mL) and decreased plasma parathyroid hormone (1.2 ± 0.7 pg/mL). Hypercalcemia and, particularly, hyperphosphatemia were of lower magnitude that what has been previously reported in the course of vitamin D intoxication in other species. However, extraskeletal calcifications were severe. The data suggest that lynx are sensitive to excessive vitamin D and extreme care should be taken when supplementing this vitamin in captive lynx diets.

    Background The continuous exposure to inorganic mercury vapour in artisanal small-scale gold mining (ASGM) areas leads to chronic health problems. It is therefore essential to have a quick, but reliable risk assessing tool to diagnose chronic inorganic mercury intoxication. This study re-evaluates the state-of-the-art toolkit to diagnose chronic inorganic mercury intoxication by analysing data from multiple pooled cross-sectional studies. The primary research question aims to reduce the currently used set of indicators without affecting essentially the capability to diagnose chronic inorganic mercury intoxication. In addition, a sensitivity analysis is performed on established biomonitoring exposure limits for mercury in blood, hair, urine and urine adjusted by creatinine, where the biomonitoring exposure limits are compared to thresholds most associated with chronic inorganic mercury intoxication in artisanal small-scale gold mining. Methods Health data from miners and community members in Indonesia, Tanzania and Zimbabwe were obtained as part of the Global Mercury Project and pooled into one dataset together with their biomarkers mercury in urine, blood and hair. The individual prognostic impact of the indicators on the diagnosis of mercury intoxication is quantified using logistic regression models. The selection is performed by a stepwise forward/backward selection. Different models are compared based on the Bayesian information criterion (BIC) and Cohen`s kappa is used to evaluate the level of agreement between the diagnosis of mercury intoxication based on the currently used set of indicators and the result based on our reduced set of indicators. The sensitivity analysis of biomarker exposure limits of mercury is based on a sequence of chi square tests. Results The variable selection in logistic regression reduced the number of medical indicators from thirteen to ten in addition to the biomarkers. The estimated level of agreement using ten of thirteen medical

    Background/Aims We assessed twelve cases of suspected chronic pesticide intoxication, with medically unexplained physical symptoms. Methods Complete blood cell count (CBC), blood chemistry, routine urinalysis, chest X-ray, ECG, gastrofiberscopy, abdominal ultrasonography, neuroselective sensory nerve conduction threshold, and psychological assessment were performed on 12 farmers who believe themselves to have suffered from chronic pesticide intoxication. Results No specific abnormalities were observed on CBC, routine urinalysis, chest X-ray, ECG, gastroscopy, abdominal ultrasonography, or peripheral nerve conduction velocity test. They persistently manifested helplessness, depression, and anxiety. The results of both psychological assessment and general physical examination revealed the following clinical features: depression (8 cases), multiple chemical hypersensitivity syndrome (2 cases), alcoholism (1 case), and religious preoccupation (1 case). Conclusion In those living in the western rural area of South Korea, depression is a prominent ongoing presentation in pesticide-exposed farmers, in addition to unexplainable physical symptoms.

    Four workers chronically exposed to elemental mental mercury in a lampsocket manufacturing factory were studied. The clinical manifestations were severe in one, mild in another, and suspicious in the remaining two. Correlation between severity of clinical features and increased urinary mercury concentrations was found. The time weighted average mercury concentrations were 0.945 mg/m3 and 0.709 mg/m3 for two workers in one room and 0.225 mg/m3 in the other. After stopping exposure, the workers recovered spontaneously or with D-penicillamine treatment within six months. It is concluded that recovery from chronic elemental mercury intoxication may be complete when patients are removed early from the exposure environment. The hazard of mercury intoxication in recycling of waste substances is emphasised. PMID:8199670

    Hyperkinésie volitionnelle is one of the involuntary movements discriminated from intention tremor. It occurs idiopathically and with cerebral infarction, head trauma, brain tumors, multiple sclerosis, hepatolenticular degeneration and polyneuropathy. Here, we report a case of toluene intoxication presenting hyperkinésie volitionnelle. A 28-year-old painter noticed a tremor of the upper extremities on December 1979. The tremor occurred both in posture and in voluntary movements. The tremor gradually developed and appeared in the legs in May 1980. Slight titubation of the trunk and head was marked in sitting posture. He showed staggering of gait. On August 1980, he exhibited slurred speech. He was admitted to the Department of Neurology of Chiba University Hospital on January 19th, 1981. Neurological examination revealed slight mental deterioration, pendular nystagmus, bradylalia, 4-5 c/s violent postural tremor of the upper extremities, action myoclonus, head and truncal titubation, mild leg tremor in sitting posture. The tremor increased terminally on finger to nose testing, and showed fast, coarse, convulsive movement (movement oppositionniste). But there was no dysmetria. The involuntary movements, above mentioned, were summarized as hyperkinésie volitionnelle. Muscle tone was hypotonic. Muscle weakness and atrophy were not seen. Deep tendon reflexes were all exaggerated, but there was no pathological reflex. He showed wide-based ataxic gait. Sensory and autonomic functions were normal. Blood, urine and cerebrospinal fluid analysis appeared normal. Electroencephalography showed 40-50 microV, 9-10 c/s alpha waves with a few fast waves.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background Patients with carbon monoxide (CO) intoxication may develop ongoing neurological and psychiatric symptoms that ebb and flow, a condition often called delayed encephalopathy (DE). The association between morphologic changes in the brain and neuropsychological deficits in DE is poorly understood. Methods Magnetic resonance imaging and neuropsychological tests were conducted on 11 CO patients with DE, 11 patients without DE, and 15 age-, sex-, and education-matched healthy subjects. Differences in gray matter volume (GMV) between the subgroups were assessed and further correlated with diminished cognitive functioning. Results As a group, the patients had lower regional GMV compared to controls in the following regions: basal ganglia, left claustrum, right amygdala, left hippocampus, parietal lobes, and left frontal lobe. The reduced GMV in the bilateral basal ganglia, left post-central gyrus, and left hippocampus correlated with decreased perceptual organization and processing speed function. Those CO patients characterized by DE patients had a lower GMV in the left anterior cingulate and right amygdala, as well as lower levels of cognitive function, than the non-DE patients. Conclusions Patients with CO intoxication in the chronic stage showed a worse cognitive and morphologic outcome, especially those with DE. This study provides additional evidence of gray matter structural abnormalities in the pathophysiology of DE in chronic CO intoxicated patients. PMID:24083408

    Forensic medical diagnostics of ethanol poisoning, alcohol abstinence, and chronic alcoholic intoxication of the mesocorticolimbic dopaminergic system remains an unresolved problem and encounters difficulties. This situation is due not only to the marked vulnerability of the neurons of the dopaminergic system but also to the fact that its mechanisms are poorly understood. The objective of the present work was to substantiate and develop diagnostic criteria for ethanol poisoning, alcohol abstinence, and chronic alcoholic intoxication of the neurons both in the mesocorticolimbic dopaminergic system and in other brain regions. The object of the study was the brain of healthy adult subjects who died from alcohol intoxication (in the period of ethanol resorption) and under conditions of alcohol abstinence (completion of the abstinence course). The purpose of the study was to elucidate factors responsible for the different degree of damage to the neurons of various identification groups (intact, hypochromic, picnomorphic, shadow) and macrogliocytes. The cells of all these types were counted at an area of 0.25 sq. mm within 4 squares each having a side of 250 mcm in length. The absolute and relative number of neurons in each group as well as the number of polyneuronal satellite cells per one intact neuron was determined. It was shown that alcohol intoxication is associated with acute swelling of and severe damage to brain neurons caused by the combination of such factors as toxic effect of ethanol, excessive production of catecholamines, and functional overstrain of dopaminergic neurons. The severity of acute alcohol damage to the neurons decreased with the distance from the mid-brain dopaminergic nuclei. Restoration of neurons during alcohol abstinence was due to compensatory activation of interactions between neurons and glial cells. It decreased in the sequence from the paranigral nucleus of the ventral portion of mesencephalic tegumentum to the medial portion of the

    In two unrelated boys, 5.3 and 3.8 years of age with hereditary fructose intolerance, apparently isolated growth retardation (-2.71 S.D. and -2.40 S.D.) occurred after infancy, even though acute symptomatic fructose intoxication was prevented by restriction of dietary fructose. When more stringent restriction of dietary fructose was instituted (approximately 40 mg per kilogram of body weight per day), growth velocity increased from the 25th to the 97th percentile in one child and from well below the 3d to above the 75th percentile in the other. When restriction of dietary fructose was experimentally relaxed (from 10 to 250 mg per kilogram per day), neither boy had symptoms, hypoglycemia, or evidence of hepatic or renal dysfunction, but both had sustained hyperuricemia and hyperuricosuria and increases in the plasma concentration and urinary excretion of magnesium. We conclude that in patients with hereditary fructose intolerance, clinically important chronic fructose intoxication can occur after infancy without causing symptoms of acute fructose intoxication and can be expressed as an apparently isolated, reversible retardation of somatic growth with a continuing disorder of adenine nucleotide metabolism, characterized in part by recurrently increased rates of degradation of adenine nucleotides.

    The aim of the study was to evaluate the effect of red wine polyphenols extract Provinols™ on the development of cardiovascular injury in the model of carbon tetrachloride (CCl4) intoxication. We followed the thoracic aorta vasoactivity and left ventricle nitric oxide (NO) synthase activity in male Wistar rats. In the preventive experiment lasting for 12 weeks the control group, the group receiving CCl4 (0.5 ml/kg) two times a week subcutaneously, the group receiving Provinols™ (30 mg/kg/day) in drinking water and the group receiving CCl4+Provinols™ was used. In the recovery experiment, the initial 12 weeks of CCl4 treatment were followed by 3 weeks of spontaneous recovery or recovery with Provinols™. CCl4-intoxication resulted in the injury of vasoactivity which was demonstrated by the inhibition of acetylcholine-induced relaxation as well as noradrenaline-induced contraction. In the preventive as well as recovery experiment administration of polyphenols refreshed endothelium-dependent relaxant response and normalized inhibited contraction to adrenergic stimuli. Provinols™ treatment significantly increased NO-synthase activity in all groups. The results revealed beneficial effects of red wine polyphenols on vascular function injured by chronic CCl4 intoxication. The correction of endothelial function seems to be attributed to the activation of NO pathway by polyphenols.

    Myelopathy in chronic toluene intoxication is rare. We present obvious lesions of the spinal cord on MRI in a 30-year-old Japanese man with chronic toluene intoxication. He had abused toluene for more than 10 years, and developed visual impairment, horizontal nystagmus, pyramidal tract signs, postural tremor, Romberg's sign, and sensory disturbance below the level of Th 2 dermatome. Anti-HTLV-1 antibody titer and vitamin B12 level in the serum were within normal limits. Biochemical analysis showed no increase of very long chain fatty acids. Cerebrospinal fluid showed no abnormal findings. Auditory brainstem response showed delay of I-V interpeak latency. Somatosensory evoked potential with the median nerve stimulation showed delay of N13-N20 central conduction time, which was later followed by absence of N14-N20 components. On MRI in T2 weighted image, marked high intensity was demonstrated in the posterior limbs of the internal capsule, and in the posterior columns and lateral tracts from the cervical through the upper thoracic cord. Cerebral lesions probably reflect demyelination and axonal degeneration produced by chronic toluene abuse. Spinal cord lesions seem to be secondary to nerve fiber changes more proximal to the nerve cell bodies.

    A temporal fall of zinc protoporphyrin (ZPP) levels in whole blood was observed in 51 patients with occupational chronic lead intoxication who were removed from exposure, treated with intravenous calcium disodium edetate (EDTA), and followed for periods up to 2273 days. ZPP levels fell, with a mean half-life of 68 days, to a mean baseline level of 36 micrograms/dl of whole blood. The baseline ZPP level was positively associated with the length of exposure (p less than .01) and the blood lead half-life (p less than .001). The amount of EDTA received had no apparent effect on ZPP levels. These data suggest that the fall of ZPP levels is largely a function of red blood cell turnover. The baseline ZPP level appears to be a useful biologic index of the biologically active pool of lead for at least two years after removal from exposure.

    As the number of diagnostic and therapeutic gastrointestinal endoscopies is increasing, and there is an increase in number of patients taking blood thinners, we are seeing more and more patients on blood thinners prior to endoscopic procedures. Gastrointestinal bleeding or thromboembolism can occur in this category of patients in the periendoscopic period. To better manage these patients, endoscopists should have a clear concept about the various blood thinners in the market. Patients’ risk of thromboembolism off anticoagulation, and the risk of bleeding from endoscopic procedures should be assessed prior to endoscopy. The endoscopic procedure should be done when it is safe to do it. PMID:27668068

    Expression of genes encoding the individual subunits of ionotropic GABAA receptor was assessed after acute and chronic intoxication of rats with ethanol. The chronic 1-month-long exposure to ethanol signifi cantly decreased (by 38%) expression of Gabrb1 gene in the hippocampus. Acute exposure to ethanol elevated expression of genes Gabrb1 (by 1.7 times), Gabra1 (by 3.8 times), and Gabra4 (by 6.5 times), although it diminished expression of Gabra2 gene by 1.4 times. In preliminarily alcoholized rats, acute intoxication with ethanol enhanced expression of genes Gabrb1 and Gabra5 by 1.7 and 8.7 times, respectively. There was neither acute nor chronic effect of ethanol on expression of gene Gabra3.

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.

    Patients with tropical ataxic neuropathy (TAN) have been shown to have chronic cyanide intoxication. Glucose tolerance test data in a group of 88 patients with TAN and 88 matched controls who were studied several years ago were analysed. A standard glucose tolerance test (SGTT) with 50 gm dextrose preceded by 50 mgs cortisone acetate orally 8 1/2 and 2 hours before the tests were performed. The SGTT was considered abnormal if the capillary blood glucose at 0.60 and 120 were greater than 120, 200 and 140 mg/100 ml (6.6, 11.1, 7.8 mmol/l) respectively. Capillary blood glucose considered abnormal for CGTT were 205 and 155 mg/100 ml at 60 and 120 (113 and 8.6 mmol/I) respectively. The SGTT was abnormal in 1 of the TAN patients and 2 controls while CGTT was abnormal in 9 TAN patients and 7 controls. However, all controls with abnormal CGTT were older than 50 years while only 1 TAN patient was older than 50 and 6 were 30 years or younger (p = 0.0105), Fischer's probability test. The results suggest a greater statistical risk for subjects with TAN 30 years or younger to have an abnormal CGTT. While this does not predict the future development of diabetes, our observation indicates the need for better designed prospective studies among such patients in developing countries.

    Chronic alcohol intoxication (CAI) increases both morbidity and mortality of stroke patients. Despite the high prevalence of CAI and ischemic stroke, studies addressing their comorbidity and/or protective alternatives remain scarce. Thus, the influence of CAI on both stroke outcome and minocycline treatment (recognized for its neuroprotective effect) was investigated. Female Wistar rats (35 days old) were treated with water or ethanol (6.5 g/kg/day, 22.5% w/v) for 55 days. Then, focal ischemia was induced by endothelin-1 in the motor cortex. Two hours later, four doses of 50 mg/kg of minocycline every 12 hours followed by five doses of 25 mg/kg every 24 hours were administered. Behavioral performance (open field and rotarod tests) and immunohistochemical (cellular density, neuronal death, and astrocytic activation) and biochemical (lipid peroxidation and nitrite levels) analyses were performed. CAI increased motor disruption, nitrite and lipid peroxidation levels, and neuronal loss caused by ischemia, whereas it reduced the astrogliosis. Minocycline was effective in preventing the motor and tissue damage caused by stroke. However, these effects were attenuated when CAI preceded stroke. Our data suggest that CAI beginning in adolescence contributes to a worse outcome in ischemic stroke survivors and reduces the benefits of minocycline, possibly requiring adjustments in therapy.

    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 < 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

    Flame deriving from paint thinner is not a rare cause of burns in Morocco and we thus considered it useful to conduct an epidemiological survey of paint thinner flame burns (PTFB) in the National Burns Centre (NBC) in the Ibn-Rochd University Hospital Centre in Casablanca, Morocco. The research covered the 10-month period from September 2007 to June 2008.The aim of our work was to present the characteristic features of such burns in order to prevent them by increasing public knowledge regarding the risks involved in using paint thinner, i.e. burns in particular. During the period in question, we colligated 17 cases of PTFB out of a total number of 356 patients admitted to the NBC for acute burns of all aetiologies. The patients' average was 32 yr and they were nearly all male (16 men/1 woman), with past histories of drug addiction and/or delinquency. They were all of low-level socioeconomic class and lived mainly in shanty towns. The burn was often secondary to street violence (92% of the cases).The mean burn surface area was 23% and the burns were often deep and located mainly in the upper limbs and the trunk.

    The aim of our work was to analyze the hemorheological parameters following partial hepatectomy in rats with chronic Al-intoxication (Al). Male Wistar rats were randomly assigned into four experimental groups (n=6 each one): Sham (rats subjected to simulated surgery); Al+Sham; Partial Hepatectomy (animals subjected to 65% liver resection) and Al+Partial Hepatectomy. Our results show that both Partial Hepatectomy and Al treatment produce a decrease of plasma cholesterol level, which showed a negative association with Rigidity Index increase (r(s)=-0.6475, p<0.05). The increase of Rigidity Index observed in Partial Hepatectomy, Al+Sham and Al+Partial Hepatectomy could be related to the increase of the proportion of non-discocytic erythrocytes, particularly stomatocytes, which determines a diminution of the Morphological Index. In the Altreated groups, greater changes in Rigidity Index and Morphological Index were observed. The relative viscosity of blood at a standard haematocrit of 40% was increased in Partial Hepatectomy, Al+Sham and Al+Partial Hepatectomy as compared to Sham, due to erythrocyte rigidity. On the other hand, we observed that the increase of plasma fibrinogen concentration correlates with augmentation of plasma viscosity (r(s)=0.689, p=0.004) for all the experimental groups studied. The results indicate that both administration of Al and Partial Hepatectomy induce microcytic hypocromic anaemia in the rats reflected by a significant decrease of haematocrit, mean corpuscular volume and mean corpuscular haemoglobin concentration. From these results, we conclude that in partially hepatectomized, Al-overloaded rats the decrease in erythrocyte deformability may be an important factor leading to the installation of anaemia.

  15. Chronic barium intoxication disrupts sulphated proteoglycan synthesis: a hypothesis for the origins of multiple sclerosis.

    PubMed

    2004-01-01

    High level contamination by natural and industrial sources of the alkali earth metal, barium (Ba) has been identified in the ecosystems/workplaces that are associated with high incidence clustering of multiple sclerosis (MS) and other neurodegenerative diseases such as the transmissible spongiform encephalopathies (TSEs) and amyotrophic lateral sclerosis (ALS). Analyses of ecosystems supporting the most renowned MS clusters in Saskatchewan, Sardinia, Massachusetts, Colorado, Guam, NE Scotland demonstrated consistently elevated levels of Ba in soils (mean: 1428 ppm) and vegetation (mean: 74 ppm) in relation to mean levels of 345 and 19 ppm recorded in MS-free regions adjoining. The high levels of Ba stemmed from local quarrying for Ba ores and/or use of Ba in paper/foundry/welding/textile/oil and gas well related industries, as well as from the use of Ba as an atmospheric aerosol spray for enhancing/refracting the signalling of radio/radar waves along military jet flight paths, missile test ranges, etc. It is proposed that chronic contamination of the biosystem with the reactive types of Ba salts can initiate the pathogenesis of MS; due to the conjugation of Ba with free sulphate, which subsequently deprives the endogenous sulphated proteoglycan molecules (heparan sulfates) of their sulphate co partner, thereby disrupting synthesis of S-proteoglycans and their crucial role in the fibroblast growth factor (FGF) signalling which induces oligodendrocyte progenitors to maintain the growth and structural integrity of the myelin sheath. Loss of S-proteoglycan activity explains other key facets of MS pathogenesis; such as the aggregation of platelets and the proliferation of superoxide generated oxidative stress. Ba intoxications disturb the sodium-potassium ion pump--another key feature of the MS profile. The co-clustering of various neurodegenerative diseases in these Ba-contaminated ecosystems suggests that the pathogenesis of all of these diseases could pivot upon a

    Enzymatic activity of Ca2+-dependent calpain proteases as well as the content and gene expression of μ-calpain (activated by micromolar calcium ion concentrations), calpastatin (inhibitor of calpains), and titin (substrate for calpains) were investigated in cardiac muscles of rats subjected to chronic alcoholization for 3 and 6 months. There was no increase in the "heart weight/body weight" parameter indicating development of heart hypertrophy in the alcoholized rats, while a decreasing trend was observed for this parameter in the rats after 6-month modeling of alcoholic cardiomyopathy, which indicated development of atrophic changes in the myocardium. Fluorometric measurements conducted using the Calpain Activity Assay Kit did not reveal any changes in total calpain activity in protein extracts of cardiac muscles of the rats alcoholized for 3 and 6 months. Western blot analysis did not show reliable changes in the contents of μ-calpain and calpastatin, and SDS-PAGE did not reveal any decrease in the titin content in the myocardium of rats after the chronic alcohol intoxication. Autolysis of μ-calpain was also not verified, which could indicate that proteolytic activity of this enzyme in myocardium of chronically alcoholized rats is not enhanced. Using Pro-Q Diamond staining, changes in phosphorylation level of titin were not detected in cardiac muscle of rats after chronic alcoholization during three and six months. A decrease in µ-calpain and calpastatin mRNA content (~1.3-fold, p ≤ 0.01 and ~1.9-fold, p ≤ 0.01, respectively) in the myocardium of rats alcoholized for 3 months and decrease in calpastatin mRNA (~1.4-fold, p ≤ 0.01) in animals alcoholized for 6 months was demonstrated using real-time PCR. These results indicate negative effect of chronic alcohol intoxication on expression of the abovementioned genes.

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

    It is established in experiments on noninbred rats that the use of imunofan (20 mg/kg daily) and polyoxidonium (150 mg/kg daily) for 7 days on the background of chronic intoxication with organophosphorus agent VX (0.01 LD50, single daily treatment for 30 days) resulted in almost complete recovery of phagocytic-metabolic activity of neutrophils, the content of lysozyme, cationic protein of platelet, and levels of proinflammatory cytokines TNFa, IL-1b and IL-6 in the blood. The administration of T-activin (20 mg/kg daily for 7 days) restores these parameters insignificantly. The maximum overall stimulatory effect was produced by polyoxidonium, while the minimum effect was observed for T-activin.

    In artisanal small-scale gold mining, mercury is used for gold-extraction, putting miners and nearby residents at risk of chronic metallic mercury vapor intoxication (CMMVI). Burden of disease (BoD) analyses allow the estimation of the public health relevance of CMMVI, but until now there have been no specific CMMVI disability weights (DWs). The objective is to derive DWs for moderate and severe CMMVI. Disease-specific and generic health state descriptions of 18 diseases were used in a pairwise comparison survey. Mercury and BoD experts were invited to participate in an online survey. Data were analyzed using probit regression. Local regression was used to make the DWs comparable to the Global Burden of Disease (GBD) study. Alternative survey (visual analogue scale) and data analyses approaches (linear interpolation) were evaluated in scenario analyses. A total of 105 participants completed the questionnaire. DWs for moderate and severe CMMVI were 0.368 (0.261–0.484) and 0.588 (0.193–0.907), respectively. Scenario analyses resulted in higher mean values. The results are limited by the sample size, group of interviewees, questionnaire extent, and lack of generally accepted health state descriptions. DWs were derived to improve the data basis of mercury-related BoD estimates, providing useful information for policy-making. Integration of the results into the GBD DWs enhances comparability.

    The histotoxic effects of chronic cyanide insult on heart, lung and pancreatic tissues, and some corroborative enzyme and metabolite changes were studied in New Zealand White rabbits using colorimetric, enzymatic and histochemical methods. Two groups of rabbits were fed for 10 months on either pure growers mash or grower mash +702 ppm inorganic cyanide. There were no significant differences in time-course profiles of serum amylase and fasting blood glucose between the cyanide-fed group and control. Pancreatic islet and heart histologies showed no pathological changes, and there were no significant differences in both serum and heart aspartate transaminase activities between the two groups. However, there were significant decreases (P<0.01) in alkaline phosphatase activity in the lungs of the cyanide-fed group, with corresponding significant (P<0.05) increases in the serum activity of the enzyme. Histological examination of lung tissue of the cyanide-treated rabbits revealed focal areas of pulmonary oedema and necrosis. These results suggest the existence of variabilities in tissue susceptibilities to the toxic effect of chronic cyanide exposure. It would appear that chronic cyanide exposure may not predispose to diabetes in the presence of adequate protein intake.

  4. Does the thrifty phenotype result from chronic glutamate intoxication? A hypothesis.

    PubMed

    Hermanussen, Michael; Tresguerres, Jesus A F

    2003-01-01

    The thrifty phenotype hypothesis proposes that the epidemiological associations between poor fetal and infant growth and the subsequent development of the metabolic syndrome, result from the effects of poor nutrition in early life. The present review however, considers an opposite explanation. We hypothesize that fetal over-nutrition plays a major role in the development of the metabolic syndrome. We found evidence that the thrifty phenotype may be the consequence of fetal hyperglutamatemia. Maternal glutamate (GLU) reaches the fetal circulation, as part of the materno-fetal glutamine-glutamate exchange. Glutamine is absorbed from the maternal circulation, and deaminated for nitrogen utilization, resulting in a fetal production of GLU. GLU is extracted as it returns to the placenta. When the umbilical plasma flow is low, GLU may be trapped in the fetal circulation, and reaches neurotoxic levels. Administering GLU to newborn rodents completely destructs arcuate nucleus neurons, and results in permanently elevated plasma leptin levels that fail to adequately counter-regulate food intake. Chronic fetal exposure to elevated levels of GLU may be caused by chronic maternal over-nutrition or by reduced umbilical plasma flow. We strongly suggest abandoing the flavoring agent monosodium glutamate and reconsidering the recommended daily allowances of protein and amino acids during pregnancy.

    Pulmonary problems are among the most common chronic complications of sulfur mustard (SM) intoxication and adversely affect patients' quality-of-life. The present trial investigated the impact of immunotherapy with interferon (IFN)-γ on quality-of-life, respiratory symptoms, and circulating immunologic and oxidative parameters in patients suffering from chronic SM-induced complications. Patients (n = 15) were administered IFNγ (100 μg) every other day for a period of 6 months. Assessment of quality-of-life [using St. George respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT) indices], the severity and frequency of respiratory symptoms, and serum levels of immunologic [including interleukin (IL)-2, IL-4, IL-6, IL-10, IFNγ, calcitonin gene related peptide (CGRP), matrix metallopeptidase (MMP)-9, and tumor necrosis factor (TNF)-α], oxidative stress [malondialdehyde (MDA) as well as total and reduced glutathione, and catalase and superoxide dismutase (SOD) activity], and fibrogenic [transforming growth factor (TGF)-β] parameters were performed at baseline and at trial end. The results indicated that IFNγ therapy is associated with improvements in SGRQ (p < 0.001) and CAT (p < 0.001) scores, decreased severity of cough (p = 0.001), dyspnea (p < 0.001), and morning dyspnea (p < 0.001), reduced frequency of sputum production (p < 0.001) and hemoptysis (p < 0.001), and elevated FEV1 (p = 0.065). Serum levels of IL-4 (p < 0.001), IL-6 (p < 0.001), IL-10 (p < 0.001), CGRP (p < 0.001), MMP-9 (p = 0.001), TNFα (p < 0.001), TGFβ (p < 0.001) and MDA (p = 0.001) were decreased while those of IL-2 (p < 0.001), IFNγ (p < 0.001), and both total (p = 0.005) and reduced glutathione (p = 0.061) increased by the end of the trial. It was concluded that IFNγ has favorable effects on the quality-of-life and alleviates respiratory symptoms in patients suffering from chronic SM

    Frequency and nosological attribution of demyelinating polyneuropathies in patients with diabetes mellitus and alcoholism were determined. Eighty-six inpatients with alcoholic (n=46) and diabetic (n=40) polyneuropathy were examined clinically and using electroneuromyography (ENMG). A demyelinating pathogenetic variant was identified by clinical and ENMG data in 27 (31%) patients. Nine patients (33%) had dysimmune polyneuropathies (acute and chronic inflammatory demyelinating polyneuropathy). Polyneuropathies were specified as toxic/metabolic with the prevalence of a demyelinating component within the main disease in 18 (67%) patients. Clinical and ENMG-signs of the demyelinating variant of alcoholic and diabetic neuropathy are presented. The efficacy of the antioxidant berlition was shown for toxic/metabolic polyneuropathies while the addition of immune modulators was needed for treatment of dysimmune polyneuropathy.

    Effects of both chronic aluminum (Al) exposure and partial hepatectomy on iron (Fe) homeostasis were studied. Male Wistar rats were intraperitoneally administered either 27 mg Al/kg body weight (as aluminum hydroxide) or the vehicle saline, three times a week for 3 mo. After this time, half of the rats of each group was sham operated (SH) and the other half was partially hepatectomized (PH). Animals of the four experimental groups (vehicle+SH [SH]; Al+SH; vehicle+PH [PH], and Al+PH) were killed 48 h after the surgical procedure. Serum, hepatic, and intestinal Al levels were found to be increased both for Al+SH and Al+PH. The serum Fe concentration and transferrin saturation percentage were significantly diminished in the rats of the Al+PH group, thus showing interaction between Al administration and PH. The 59Fe mucosal-to-serosal transport, studied in the intestinal loop in situ, was not affected by Al or PH. The malregulation of intestinal Fe absorption in Al exposure and/or PH when the serum Fe concentration was diminished could be the result of the increased lipid peroxidation (thiobarbituric acid-reactive substances [TBARS]) observed in this tissue. Mucosal TBARS were increased by Al exposure (+26%) and PH (+37%) and interaction between Al and PH was observed (+44%). These results show that when liver surgery is performed after prolonged Al exposure, it leads to impairment of Fe homeostasis. We underline the importance of the exposure to Al, a potentially toxic element, in the study of risk assessment in patients who must be submitted to major liver resection.

    Objectives Alcohol is responsible for a proportion of emergency admissions to hospital, with acute alcohol intoxication and chronic alcohol dependency (CAD) implicated. This study aims to quantify the proportion of hospital admissions through our emergency department (ED) which were thought by the admitting doctor to be (largely or partially) a result of alcohol consumption. Setting ED of a UK tertiary referral hospital. Participants All ED admissions occurring over 14 weeks from 1 September to 8 December 2012. Data obtained for 5497 of 5746 admissions (95.67%). Primary outcome measures Proportion of emergency admissions related to alcohol as defined by the admitting ED clinician. Secondary outcome measures Proportion of emergency admissions due to alcohol diagnosed with acute alcohol intoxication or CAD according to ICD-10 criteria. Results 1152 (21.0%, 95% CI 19.9% to 22.0%) of emergency admissions were thought to be due to alcohol. 74.6% of patients admitted due to alcohol had CAD, and significantly greater than the 26.4% with ‘Severe’ or ‘Very Severe’ acute alcohol intoxication (p<0.001). Admissions due to alcohol differed to admissions not due to alcohol being on average younger (45 vs 56 years, p<0.001) more often male (73.4% vs 45.1% males, p<0.001) and more likely to have a diagnosis synonymous with alcohol or related to recreational drug use, pancreatitis, deliberate self-harm, head injury, gastritis, suicidal ideation, upper gastrointestinal bleeds or seizures (p<0.001). An increase in admissions due to alcohol on Saturdays reflects a surge in admissions with acute alcohol intoxication above the weekly average (p=0.003). Conclusions Alcohol was thought to be implicated in 21% of emergency admissions in this cohort. CAD is responsible for a significantly greater proportion of admissions due to alcohol than acute intoxication. Interventions designed to reduce alcohol-related admissions must incorporate measures to tackle CAD. PMID:27324707

    Experiments on noninbred albino rats showed that a chronic exposure to organophosphorus compounds (carbophos and metaphos, 30 days, total dose 0.3 LD50) is primarily followed by a decrease in the immune reactions and IFN-γ associated with Th1 lymphocyte function (in comparison with the immune response due to activation of Th2 cells by IL-4). The concentrations of IL-2, IL-6, and IL-10 in the blood decreased after 30-day intoxication. The immune reactions associated with functional activity of Th1 and Th2 lymphocytes were shown to decrease similarly after chronic treatment with organophosphorus compounds for 60 days (total dose 0.6 LD50). This exposure was accompanied by a decrease in the concentrations of IFN-γ, IL-4, IL-2, and IL-6, but had no effect on the level of IL-10 in the blood.

    Pulmonary problems are among the most frequent chronic complications of sulfur mustard (SM) intoxication and are often accompanied by deregulated production of pro-inflammatory cytokines. Curcuminoids, comprising curcumin, demethoxycurcumin and bisdemethoxycurcumin, are phytochemicals with remarkable anti-inflammatory properties that are derived from dried rhizomes of the plant Curcuma longa L. (turmeric). The present pilot study aimed to investigate the clinical effects of supplementation with curcuminoids on markers of pulmonary function and systemic inflammation in SM-intoxicated subjects. In a randomized double-blind placebo-controlled trial, 89 male subjects who were suffering from chronic SM-induced pulmonary complications were recruited and assigned to either curcuminoids (500 mg TID per oral; n=45) or placebo (n=44) for a period of 4 weeks. Efficacy measures were changes in the spirometric parameters (FVC, FEV1, FEV1/FVC) and serum levels of inflammatory mediators including interleukins 6 (IL-6) and 8 (IL-8), tumor necrosis factor-α (TNFα), transforming growth factor-β (TGFβ), high-sensitivity C-reactive protein (hs-CRP), calcitonin gene related peptide (CGRP), substance P and monocyte chemotactic protein-1 (MCP-1). 78 subjects completed the trial. Although FEV1 and FVC remained comparable between the groups, there was a greater effect of curcuminoids vs. placebo in improving FEV1/FVC (p=0.002). Curcuminoids were also significantly more efficacious compared to placebo in modulating all assessed inflammatory mediators: IL-6 (p<0.001), IL-8 (p=0.035), TNFα (p<0.001), TGFβ (p<0.001), substance P (p=0.016), hs-CRP (p<0.001), CGRP (p<0.001) and MCP-1 (p<0.001). Curcuminoids were safe and well-tolerated throughout the trial. Short-term adjunctive therapy with curcuminoids can suppress systemic inflammation in patients suffering from SM-induced chronic pulmonary complications.

    A 21-day-old boy presented to our emergency department hypotonic, lethargic, and intermittently unresponsive to pain. A workup for ketoacidosis, sepsis, and central nervous system hemorrhage was negative. A urine drug screen collected eight hours after hospitalization showed 39 mg/dl of isopropyl alcohol and 76 mg/dl of acetone. The first serum drug analysis was not performed until 18 hours after admission, at a time when there had been clinical improvement. The isopropyl alcohol concentration was 8 mg/dl, and the acetone concentration was 203 mg/dl. Management was supportive, and the patient stabilized. He was discharged from the hospital in good health in three days. A further review of the history showed no evidence for an oral exposure to isopropyl alcohol. However, since leaving the maternity hospital the mother had been applying gauze pads or cotton balls soaked with isopropyl alcohol to the umbilicus with every diaper change. We conclude that the child suffered from an isopropyl alcohol intoxication that occurred by absorption through the umbilical area.

    The purpose of the study was to disentangle the relative contributions of day-of-injury alcohol intoxication and pre-injury alcohol misuse on outcome from TBI. Participants were 142 patients enrolled from a Level 1 Trauma Center (in Vancouver, Canada) following a traumatic brain injury (TBI; 43 uncomplicated mild TBI and 63 complicated mild-severe TBI) or orthopedic injury [36 trauma controls (TC)]. At 6-8 weeks post-injury, diffusion tensor imaging (DTI) of the whole brain was undertaken using a Phillips 3T scanner. Participants also completed neuropsychological testing, an evaluation of lifetime alcohol consumption (LAC), and had blood alcohol levels (BALs) taken at the time of injury. Participants in the uncomplicated mild TBI and complicated mild-severe TBI groups had higher scores on measures of depression and postconcussion symptoms (d = 0.45-0.83), but not anxiety, compared with the TC group. The complicated mild-severe TBI group had more areas of abnormal white matter on DTI measures (all p < .05; d = 0.54-0.61) than the TC group. There were no difference between groups on all neurocognitive measures. Using hierarchical regression analyses and generalized linear modeling, LAC and BAL did provide a unique contribution toward the prediction of attention and executive functioning abilities; however, the variance accounted for was small. LAC and BAL did not provide a unique and meaningful contribution toward the prediction of self-reported symptoms, DTI measures, or the majority of neurocognitive measures. In this study, BAL and LAC were not predictive of mental health symptoms, postconcussion symptoms, cognition, or white-matter changes at 6-8 weeks following TBI.

    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.

    PubMed Central

    1984-01-01

    An outbreak of spastic paraparesis which mostly affected women and children occurred in a northern province of Mozambique in 1981. The epidemic was related to chronic cyanide intoxication associated with a diet consisting almost exclusively of cassava. A prolonged drought in the area had exhausted all food resources except cassava, especially the bitter varieties. A nutritional, toxicological and botanical investigation was carried out in two of the five districts affected. The main findings were that cyanide levels were unusually high in the cassava plant as a consequence of the drought with daily intakes estimated at 15-31.5 mg HCN. Detoxification of the bitter varieties by sun-drying was inadequate because of the general food shortage, and metabolic detoxification was probably reduced owing to the absence of sulfur-containing amino acids in the diet. The raw and dried uncooked cassava was eaten mostly by women and children. The nutritional status of the population, however, was not very poor and symptoms of advanced under-nutrition were rarely seen. PMID:6088100

    Changes in biochemical mechanisms and amine concentrations in the brain have been manifested in the form of varying disorders and abnormalities in behavior, including motor-activity, which has been proved with a number of psychoactive drugs. It has been reported that increased level of cerebral norepinephrine (NE) has been shown to be associated with motor hyper-activity, and in lead exposed rats. No study is available which could account for the pattern of changes in spontaneous ambulatory responses in an open field situation together with the steady state regional levels of NE in the brain of chronically lead exposed rats. Therefore, it seemed to be worthwhile to study the circadian rhythm of ambulatory activity and its association with NE levels in various brain regions of rats exposed to lead.

    Exposure to either environmental toxicants or chronic hyperglycaemia could impair male reproductive function. However, the extent to which exposure to such toxicants, in the presence of pre-existing metabolic dysfunction, could affect male reproduction is unclear. Streptozotocin-induced diabetic Wistar rats (12 weeks old) were exposed to oral aluminium chloride at 250 ppm for 30 days; followed by evaluation of caudal epididymal sperm count and motility, assay for serum follicle stimulating hormone (FSH), testosterone (T) and oestradiol; and assessment of testicular histology. Moreover, blood glucose was evaluated by the glucose oxidase method. In rats treated with streptozotocin (STZ) or aluminium (Al) alone, erosion of testicular parenchyma and stroma was observed. This effect was most severe in diabetic rats simultaneously exposed to Al; coupled with reduced caudal epididymal sperm count that was least in this (STZ+Al) group (18.75 × 10(6)  ml(-1) ) compared with controls (61.25 × 10(6)  ml(-1) ; P < 0.05), STZ group or Al group. Moreover, these reproductive perturbations (in the STZ+Al group) were associated with reduced sperm motility and significantly reduced serum FSH (P < 0.05); but elevated serum T and oestradiol (P < 0.05), compared with control. These suggest that diabetes-induced testicular lesion is exacerbated by simultaneous oral Al toxicity in Wistar rats.

    Alcohol and drugs have been linked to severe violent offending among women as well as men. The purpose of this study was to make a contribution to the limited knowledge of characteristics related to the state of intoxication in violent female offenders. The putative differences in the characteristics of female offenders and their violent offenses in relation to the state of intoxication at the time of the violent offending were examined. Of a nation-wide sample of 109 female offenders found guilty of homicide and other violent crimes and incarcerated in 1999-2000 in Finland, 60 offenders participated in the study. Of these offenders 49 (81.7%) had been intoxicated at the time the of index offenses. These were compared with 11 (18.3%) non-intoxicated offenders using a structured interview, the Structured Clinical Interview II for DSM-IV (SCID-II) and the Hare Psychopathy Checklist-Revised (PCL-R). The prevalence of substance abuse or dependence (73.3% and 0%), personality disorder (89.6% and 36.4%), particularly antisocial personality disorder (66.7% and 0%), as well as a history of criminality (69.4% and 0%) were significantly higher among the intoxicated women than among the non-intoxicated. The PCL-R scores were also significantly higher among the intoxicated offenders than among non-intoxicated offenders. The victims of the intoxicated women (23.9%) were less often emotionally close to the perpetrator than were the victims of the non-intoxicated women (66.6%). No differences emerged between the groups in experiences of childhood and adulthood abuse or stressful life events prior to the index crime. The findings indicate that intoxicated violent female offenders exhibit more of the characteristics previously found in violent men, than do the non-intoxicated female offenders. Moreover, the non-intoxicated group comprises both psychotic non-responsible and non-psychotic, fairly well-adjusted women, who are educated, working or studying at the time of the offense

    Alcohol is known to produce profound effects on blood; during chronic intoxication, prolongation of bleeding time has been reported. Utilizing human platelet rich plasma, we have studied the effect of alcohol on epinephrine, arachidonic acid and ADP induced aggregation. Control responses were obtained with saline from which the relative inhibition by alcohol was calculated. These studies were carried out at a concentration of 1.25-5.0 mg/ml which represents 0.125-0.5% alcohol blood levels. From 25 normal male and female volunteers, without prior hemostatic defects or drug ingestion, a dose-dependent inhibition by alcohol of all three agonist induced aggregations was noted. Alcohol itself did not produce any aggregation response. These studies demonstrate that alcohol at levels which are reached during intoxication is capable of impairing platelet function. The implication of this finding on the bleeding complications in healthy intoxicated patients may be significant during traumatic events, and individuals taking antiplatelet drugs may present a more serious hemostatic deficit during alcohol intoxication.

    Industrial solvents mixed from thinner, used in paints, leathers, rubber, varnishes, have neurotoxic action. By laboral inhalation or spontaneously these are absorbed from the lungs, transported by blood and because of this high lipophilic section are retained within the lipid rich nervous system. Euphoric effects appear accompanied with visual and additive halucinations. In chronic abusers it produce schizophrenic-paranoid consequences with encephalic and peripheral neuronal and nervous fibers destruction, accompanied of blindness and paralysis. Cocaine is another neurotoxic drug. At first it produces euphoria, arterial hypertension and symptoms suggestive of underlying psychiatric diseases. The cocaine addicts often suffer depression, paranoia, hallucinations, seizures and suicidal ideation. The morphological base of the symptomatology is the encephalic and peripheral neuronal and nerve fibers destruction.

    Humans can come into contact with thinner by occupational exposure or by intentional inhalation abuse. Numerous studies of workers for genotoxic effects of thinner exposure have yielded conflicting results, perhaps because co-exposure to variable other compounds cannot be avoided in workplace exposure studies. In contrast, there is no data concerning the genotoxic effects of intentional inhalation abuse. The aim of this project was to examine the genotoxic effects of thinner inhalation in an animal model of thinner abuse (rats exposed to 3000 ppm toluene, a high solvent concentration over a very short, 15 min time period, twice a day for 6 weeks). The data presented here provides evidence that thinner inhalation in our experimental conditions is able to induce weight loss, lung abnormalities and oxidative stress. This oxidative stress induces oxidative DNA damage that is not a characteristic feature of genotoxic damage. No significant difference in DNA damage and DNA repair (biomarkers of genotoxicity) in lymphocytes from thinner-treated and control rats was found. Lead treatment was used as a positive control in these assays. Finally, bone marrow was evaluated as a biomarker of cellular alteration associated with thinner inhalation. The observed absence of hemopoietic and genetic toxicity could be explained in part by the absence of benzene, the only carcinogenic component of thinner; however, benzene is no longer a common component of thinner. In conclusion, thinner did not cause genotoxic effects in an experimental model of intentional abuse despite the fact that thinner inhalation induces oxidative stress.

    Rationale Consumption of alcohol begins during late adolescence in a majority of humans, and the greatest drinking occurs at 18–25 years then decreases with age. Objectives The present study measured differences in ethanol intake in relation to age at the onset of ethanol access among non-human primates to control for self-selection in humans and isolate age effects on heavy drinking. Methods Male rhesus macaques were assigned first access to ethanol during late adolescence (n = 8), young adulthood (n = 8) or early middle age (n = 11). The monkeys were induced to drink ethanol (4% w/v in water) in increasing doses (water, 0.5 g/kg, 1.0 g/kg, 1.5 g/kg) using a fixed-time (FT) 300-s schedule of food delivery, followed by 22 hours/day concurrent access to ethanol and water for 12 months. Age-matched controls consumed isocaloric maltose-dextrin solution yoked to the late adolescents, expected to be rapidly maturing (n = 4). Results Young adult monkeys had the greatest daily ethanol intake and blood-ethanol concentration (BEC). Only late adolescents escalated their intake (ethanol, not water) during the second compared to the first 6 months of access. On average, testosterone was consistent with age differences in maturation, and tended to increase throughout the experiment more for control than ethanol-drinking adolescent monkeys. Conclusions Young adulthood in non-human primates strongly disposes toward heavy drinking independently of sociocultural factors present in humans. Drinking ethanol to intoxication during the critical period of late adolescence is associated with escalation to heavy drinking. PMID:24448900

    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

    The Arctic is coming to be dominated by young ice, much of it seasonal. Many of our observations of the radiative properties of sea ice come from drifting stations on thick, multi-year ice. To better understand the Arctic climate system in a warmer world, we need more data about the radiative properties and their seasonal and spatial variability on thinner, younger ice. Since this younger ice is not always thick enough to support lengthy drifting stations, there is a need for new technologies to help us get optical measurements on seasonal ice. One challenge is obtaining seasonal data on ice that is too weak to support even a ship-based camp, and especially to have these observations extend well into the melt season. For these situations, we have developed a spectral radiation monitoring buoy that can be deployed during a one-day ice station, and that can then autonomously observe the spectral albedo and transmittance of the sea ice, transmitting all data in near real time by satellite, until the buoy melts out. Similar installations at manned or regularly visited sites have provided good data, with surprisingly few data-quality problems due to frost, precipitation, or tilting. The buoys consist of 3 spectral radiometers, covering wavelengths 350 to 800 nm, and a datalogger with an Irridium modem. The datalogger and necessary batteries are inside a sealed housing which is frozen into a hole drilled in the ice. Arms extend from both the top and bottom of the housing, holding sensors that measure incident, reflected, and transmitted spectra. The under-ice radiometer is equipped with a bioshutter to avoid algal growth on the sensor. They will be deployed alongside ice mass balance buoys, providing data about the physical development of the ice and snow, as well as position. While the buoys provide an excellent record of diurnal, synoptic, and seasonal variability, they are fixed to one location in the ice, so other methods are still needed for measuring the spatial

    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.

  18. Blood purification for intoxication.

    PubMed

    Nakae, Hajime

    2010-01-01

    Blood purification is administered in cases of acute intoxication when the substance causing the intoxication is to be eliminated or when the substance leads to a case of organ dysfunction, such as in renal or hepatic failure. The causative substances cover a wide range, from medical drugs or agrichemicals to natural poisons (such as poisonous mushrooms). In removing these substances, gastric lavage, activated carbon administration, laxative administration or enema cleaning are the preferred methods, and blood purification is not routinely conducted. However, when the causative substance is unknown or when there are several causative substances, it is not easy to immediately grasp the disposition of the patient and so judge whether or not blood purification should be performed. In such cases, blood purification must be conducted in a timely manner and in accordance with the crisis management principle of 'prepare for the worst'. In general, substances whose molecular weight is within the removal spectrum, having a small distribution volume and a low protein-binding rate, are easier to remove. For substances with high protein-binding rates, albumin dialysis (MARS and Prometheus) is performed in order to remove albumin-binding substances. Since MARS and Prometheus have not been introduced in Japan, plasma diafiltration, employing selective plasma filtration with dialysis, is a practical alternative.

The rise in plasma osmolalty causes ADH release, stimulation of thirst and water intake. Acute water intoxication is exceptional in patients without a chronic psychiatric disease. Herein, we describe a case of acute water intoxication in a previously healthy patient, after making an intravenous urography. The excessive water intake and the impossibility of renal water loss because of streee-induced ADH release originated t. Only nine cases have been previously described; almost they all were women preparing for diagnostic procedures.

  20. Carbon monoxide intoxication

    SciTech Connect

    Carbon monoxide poisoning usually results from inhalation of exhaust fumes from motor vehicles, smoke from fires or fumes from faulty heating systems. Carbon monoxide has a high affinity for hemoglobin, with which it forms carboxyhemoglobin. The resulting decrease in both oxygen-carrying capacity and oxygen release can lead to end-organ hypoxia. The clinical presentation is nonspecific. Headache, dizziness, fatigue and nausea are common in mild to moderate carbon monoxide poisoning. In more severe cases, tachycardia, tachypnea and central nervous system depression occur. When carbon monoxide intoxication is suspected, empiric treatment with 100 percent oxygen should be initiated immediately. The diagnosis is confirmed by documenting an elevated carboxyhemoglobin level. Hyperbaric oxygen therapy is recommended in patients with neurologic dysfunction, cardiac dysfunction or a history of unconsciousness. 26 refs.

  1. Chelation in Metal Intoxication

    Chelation therapy is the preferred medical treatment for reducing the toxic effects of metals. Chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. 2,3-Dimercaprol has long been the mainstay of chelation therapy for lead or arsenic poisoning, however its serious side effects have led researchers to develop less toxic analogues. Hydrophilic chelators like meso-2,3-dimercaptosuccinic acid effectively promote renal metal excretion, but their ability to access intracellular metals is weak. Newer strategies to address these drawbacks like combination therapy (use of structurally different chelating agents) or co-administration of antioxidants have been reported recently. In this review we provide an update of the existing chelating agents and the various strategies available for the treatment of heavy metals and metalloid intoxications. PMID:20717537

    Methyl bromide is a highly toxic gas with poor olfactory warning properties. It is widely used as insecticidal fumigant for dry foodstuffs and can be toxic to central and peripheral nervous systems. Most neurological manifestations of methyl bromide intoxication occur from inhalation. Acute toxicity characterized by headache, dizziness, abdominal pain, nausea, vomiting and visual disturbances. Tremor, convulsion, unconsciousness and permanent brain damage may occur in severe poisoning. Chronic exposure can cause neuropathy, pyramidal and cerebellar dysfunction, as well as neuropsychiatric disturbances. The first case of methyl bromide intoxication in Thailand has been described. The patient was a 24-year-old man who worked in a warehouse of imported vegetables fumigated with methyl bromide. He presented with unstable gait, vertigo and paresthesia of both feet, for two weeks. He had a history of chronic exposure to methyl bromide for three years. His fourteen co-workers also developed the same symptoms but less in severity. Neurological examination revealed ataxic gait, decreased pain and vibratory sense on both feet, impaired cerebellar signs and hyperactive reflex in all extremities. The serum concentration of methyl bromide was 8.18 mg/dl. Electrophysilogical study was normal. Magnetic resonance imaging of the brain (MRI) revealed bilateral symmetrical lesion of abnormal hypersignal intensity on T2 and fluid-attenuation inversion recovery (FLAIR) sequences at bilateral dentate nuclei of cerebellum and periventricular area of the fourth ventricle. This incident stresses the need for improvement of worker education and safety precautions during all stages of methyl bromide fumigation.

    Used primarily as a fumigant or as a substrate in chemical processes, methyl bromide is a highly toxic gas. The gas is usually absorbed by inhalation and effects on the lungs, gastrointestinal tract, skin, and brain are seen. Numerous instances of acute and chronic neurologic injury have been reported: acute poisoning results in seizures, myoclonus, ataxia or cerebral oedema beginning as early as 30 min after exposure while subacute or chronic intoxication presents with diverse slowly progressive neurological and neurobehavioral symptoms. Serum bromide levels may be elevated, but often return rapidly to normal. Electroencephalography may show frontally-predominant slow waves or polyspikes with following slow wave, and MRI reveals characteristic involvement in the dentate nucleus of the cerebellum, the brainstem, and the splenium of the corpus callosum. Symmetric and selective lesions in characteristic sites are observed on imaging and on histopathological examination. These are likely produced by methylation of intracellular lipids, protein and glutathione; production of toxic metabolites; defective neurotransmitter function; and abnormal oxidative phosphorylation. This article reviews the toxic effects of this gas, the pathophysiology and symptoms of its effects on the nervous system, and characteristic findings on MRI; and presents an illustrative case of methyl bromide intoxication due to exposure at a factory producing the compound commercially.

    It is commonly said that tall people look thinner. Here, we asked whether an illusion exists such that the taller of two equally wide stimuli looks thinner, and conversely whether the thinner of two equally tall stimuli looks taller. In five experiments, participants judged the horizontal or vertical extents of two identical bodies, rectangles, or cylinders that differed only in their vertical or horizontal extents. Our results confirmed the folk wisdom that being tall makes you look thinner. We similarly found that being thin makes you look taller, although this effect was less pronounced. The same illusion was present for filled rectangles and cylinders, but it was consistently stronger for both photographs and silhouettes of the human body, raising the question of why the human form should be more prone to this illusion.

    Methoxetamine (MXE) is a new synthetic drug of abuse structurally related to ketamine and phencyclidine. A case of a 29-year-old male with acute toxicity related to the analytically confirmed use of MXE is reported. The man was found dead at his residence. Biological material was analyzed using liquid chromatography-tandem mass spectrometry. The concentration of MXE in urine of the deceased was 85 μg/mL. Despite the vial containing the blood sample being destroyed during transportation and the blood leaking out into the cardboard packaging, the blood level of MXE was estimated. After determination of the cardboard grammage (approx. 400 g/m(3) ) and the mean mass of the blood obtained after drying (0.1785 ± 0.0173 g per 1 mL), the estimated blood concentration of MXE was found to be 5.8 μg/mL. The high concentration of MXE in blood and urine and the circumstances of the case indicate an unintentional, fatal intoxication with this substance.

    When humans encounter marine creatures a variety of maladies may occur, ranging from dermatitis to life-threatening trauma, allergy, envenomations, or intoxications. The emergency physician should be prepared to recognize quickly and address appropriately the potential life threats, which are primarily neurologic, respiratory, and cardiovascular. A high degree of suspicion for these illnesses is needed. Intoxications may be especially confusing. Although most of the syndromes are self-limited and treatment supportive, time is of the essence if neuromuscular paralysis, hypotension, or respiratory compromise is present. Much folklore exists regarding detection and prevention of these entities and should be regarded as such. The last several decades have seen a marked increase in our knowledge base regarding these fascinating envenomations and intoxications. Research in the next several decades probably will produce a variety of diagnostic and therapeutic tools, which will further our understanding of, and ability to specifically manage, these syndromes.

    Water intoxication is a common disorder in calves and is usually characterized by transient hemoglobinuria. In contrast, the condition is very rare in adult cattle, with few reports on naturally occurring cases. In the present report, four female Japanese Black cattle, aged 16-25 months, showed neurological signs when they drank water following a water outage. Hemoglobinuria was not grossly observed, while severe hyponatremia was revealed by laboratory tests. Autopsy indicated cerebral edema with accumulation of serous fluid in expanded Virchow-Robin spaces. These results indicate the possibility of water intoxication associated with cerebral edema due to severe dilutional hyponatremia in adult cattle.

    A young man with bipolar disorder was admitted in a coma. Cerebral oedema secondary to severe hyponatraemia was implicated. This was due to self-induced water intoxication. He developed rhabdomyolysis, a massive creatine kinase (out of proportion to longstanding antipsychotic medication) and acute renal failure. In the intensive care unit, hyponatraemia was corrected, and following appropriate fluid resuscitation, with forced alkaline diuresis, the rhabdomyolysis and renal function normalised, averting renal support. While a full recovery ensued, the persisting risk factors for hyponatraemia, that is polydipsia, and its association with rhabdomyolysis, increased the chances of a recurrence. Closely supervised regulation of his water intake, and monitoring of antipsychotic efficacy (for biochemical homeostatsis) are essential for secondary prevention. Rhabdomyolysis is a rare complication of hyponatraemia. When associated with psychogenic polydipsia, the acute and chronic management are challenging. Vaptans, which are aquaretics, that preferentially prevent renal tubular water reabsorption, may be beneficial in this situation. PMID:22778200

    There have been several reports of disulfiram intoxication, but little evidence of neurologic conditions resulting from disulfiram-induced brain damage combined with Wernicke encephalopathy-associated lesions. We report a rare patient with both Wernicke encephalopathy and disulfiram intoxication. This 50-year-old woman, who was taking disulfiram for chronic alcohol abuse, presented with an acute confusional state, dysarthria, nystagmus, supranuclear ophthalmoplegia, and paraparesis. Biochemical serum and cerebrospinal fluid analyses were normal. An electromyogram detected a motor polyneuropathy. Cognitive assessment revealed severe impairment of memory, attention, and logical and executive abilities. Magnetic resonance imaging with gadolinium enhancement showed brain lesions consistent with Wernicke encephalopathy, but also symmetric hyperintensities on T2-weighted images in the globus pallidus. Stopping the disulfiram and treating with hydration, high-dose thiamine supplements, and benzodiazepines significantly improved the patient's consciousness and oculomotor function. A magnetic resonance imaging scan after 1 month of treatment showed complete disappearance of the brain lesions and the hyperintensities in the globus pallidus. After a further month of intensive neurorehabilitation, the patient was able to interact with the medical staff, and her neuropsychological tests showed only mild memory impairment. Patients with alcoholism who present at emergency departments are at high risk for misdiagnosis, especially because there is no specific routine laboratory test for detecting asymptomatic disulfiram intoxication. Although uncommon, the combination of Wernicke encephalopathy and disulfiram intoxication should be suspected in patients with alcoholism. The disorder can be detected through a careful history and prompt clinical evaluation, together with characteristic magnetic resonance imaging findings.

    Lacquer thinner, commonly used for removing household paints, is known to contain various aromatic hydrocarbons and naphtha; if ingested, may cause methaemoglobinemia. We report a case of 13-year-old girl who presented with episodes of vomiting, abdominal pain and numbness of limbs. Peripheral blood smear showed few fragmented erythrocytes and 10-12 nucleated red blood cells /100 white blood cells. Reticulocyte count was 15% with presence of Heinz bodies. There was a history of accidental ingestion of lacquer paint thinner. Levels of methaemoglobin were very high along with raised HbA2 levels. An impression of haemolytic anaemia, due to lacquer thinner paint poisoning, with methaemoglobinemia was given. Incidentally High Performance Liquid Chromatography (HPLC) revealed increased HbA2 levels i.e., heterozygous inheritance of beta thalassaemia minor. Patient responded well to methylene blue. Blood transfusion was performed and symptomatic treatment was given. PMID:28050380

    Toluene is an aromatic hydrocarbon (C7H8) found in gasoline, acrylic paints, varnishes, lacquers, paint thinners, adhesives, and shoe polish. Toluene toxicity can occur from unintentional or deliberate inhalation of fumes, ingestion, or transdermal absorption. Unintentional exposure to high concentrations of toluene results in severe toluene intoxication. This is a report of toluene poisoning in a middle-age man found dead at home after varnish application by spray. There was no obvious external and internal cause of death. The blood test revealed the presence of toluene. The cause of death was diagnosed as cardiopulmonary failure caused by toluene, which is a rare case report in Thailand.

    Vitamin D participates in mineral homeostasis, immunomodulation, cell growth and differentiation. The leaves of Solanum glaucophyllum contain high levels of 1,25-dihydroxyvitamin D3 as glycoside derivatives and their chronic ingestion generates a hypervitaminosis D-like state. We analyzed changes on carbohydrate expression as a cell differentiation indicator on samples of the small and large intestine of S. glaucophyllum-intoxicated rabbits, using conventional and lectin histochemistry. Male New Zealand white rabbits were intoxicated with S. glaucophyllum during two or four weeks and killed the day after. A group of animals ("possibly recovered group") were intoxicated during 15 days and killed at day 45 of the beginning of the experiment. We found changes in the lectin binding pattern in the small and large intestine of the intoxicated rabbits. Some of these changes were reverted in the possibly recovered group. Vitamin D could be a new regulator factor of the intestinal glycosylation process.

    1984-07-01

    Arsenic-induced deaths have been known to occur from accidental poisoning, as a result of medical therapy, and from intentional poisonings in homicide and suicide. Twenty-eight arsenic deaths in North Carolina from 1972 to 1982 included 14 homicides and seven suicides. In addition, 56 hospitalized victims of arsenic poisoning were identified at Duke Medical Center from 1970 to 1980. Four case histories of arsenic poisoning in North Carolina are presented and clinical manifestations are discussed. In view of the continued widespread use of arsenic in industry and agriculture, and its ubiquity in the environment, arsenic poisoning will continue to occur. A need for knowledge of its toxicity and of the clinical manifestations of acute and chronic arsenic poisoning will also continue.

    The lithography challenges posed by the 22 nm node continue to place stringent requirements on photomasks. The dimensions of the mask features continue to shrink more deeply into the sub-wavelength scale. In this regime residual mask electromagnetic field (EMF) effects due to mask topography can degrade the imaging performance of critical mask patterns by degrading the common lithography process window and by magnifying the impact of mask errors or MEEF. Based on this, an effort to reduce the mask topography effect by decreasing the thickness of the mask absorber was conducted. In this paper, we will describe the results of our effort to develop and characterize a binary mask substrate with an absorber that is approximately 20-25% thinner than the absorber on the current Opaque MoSi on Glass (OMOG) binary mask substrate. For expediency, the thin absorber development effort focused on using existing absorber materials and deposition methods. It was found that significant changes in film composition and structure were needed to obtain a substantially thinner blank while maintaining an optical density of 3.0 at 193 nm. Consequently, numerous studies to assess the mask making performance of the thinner absorber material were required and will be described. During these studies several significant mask making advantages of the thin absorber were discovered. The lower film stress and thickness of the new absorber resulted in improved mask flatness and up to a 60% reduction in process-induced mask pattern placement change. Improved cleaning durability was another benefit. Furthermore, the improved EMF performance of the thinner absorber [1] was found to have the potential to relieve mask manufacturing constraints on minimum opaque assist feature size and opaque corner to corner gap. Based on the results of evaluations performed to date, the thinner absorber has been found to be suitable for use for fabricating masks for the 22 nm node and beyond.

    A 4-year-8-month-old boy was brought to our emergency department with coma and seizure. Initial physical examination showed evidence of physical child abuse and sudden body weight gain of 3.4 kg in one day. The laboratory results showed normal renal function with severe hyponatremia and the MRI study showed diffuse brain swelling. All of these findings were compatible with the diagnosis of acute water intoxication. Careful history taking from the boy and his parents separately confirmed the course of chronic polydipsia with acute compulsive water drinking. After clinical assessment and follow-up by psychiatrist, the patient was diagnosed with hyperactivity disorder. We present this case and show the possibility of correlation between compulsive water drinking, child abuse and hyperactivity disorder on acute water intoxication.

    According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicated, placebo, and sober witnesses observed a live, staged theft, overheard subsequent misinformation about the theft, and took part in an investigative interview. Participants generally believed they witnessed a real crime and experienced a real interview. Intoxicated witnesses were not different from placebo or sober witnesses in the number of accurate details, inaccurate details, or "don't know" answers reported. All the participants demonstrated a misinformation effect, but there were no differences between intoxication levels: Intoxicated participants were not more susceptible to misinformation than sober or placebo participants. Results are discussed in the light of their theoretical and applied relevance.

White-matter damage in the centrum semiovale and periventricular area and abnormalities in the globus pallidus are most commonly seen on MRI following CO exposure. Though not as common, toxic or ischemic peripheral neuropathies are associated with CO exposure in humans and animals. The cornerstone for treatment for CO poisoning is 100% oxygen using a tight-fitting mask for greater than 6 hours. The indications for treatment with hyperbaric oxygen to decrease the half-life of COHb remain controversial.

    Silicone fibers were synthesized by electrospinning, where 17 solvents with different chemical properties (boiling point, conductivity, viscosity, dielectric constant, and solubility parameter) were used to dissolve the silicone polymer for the formation of fibers through electrospinning. Previous reports on the miniaturization of fibers of polymers dissolved in a solvent suggested that the low viscosity and the high conductivity of the polymer solution were the key parameters to form thinner fibers when using a single solvent. Here we have found a powerful way to search for good solvents to reduce the fiber diameters as well as to dissolve the polymers. By considering different types of solvents, it was found that the solubility parameters conclusively determined the smallest fiber diameters of the silicone polymers. The solubility parameter of the silicone polymer should be lower than those of the solvents to make thinner fibers. The results have revealed the strong relationship between the diameters of the fibers and the solubility parameters of the solvents, and they indicate that the solubility parameter could be a good indicative parameter in selecting solvents during the fabrication of thinner fibers by electrospinning, especially for siloxane polymers.

    Three patients presented with an intoxication caused by Aconitum napellus, commonly known as Aconite, Monkshood or Wolfsbane. The first patient, a woman aged 24, was resuscitated after accidental ingestion of plant material 'from nature'. She experienced severe ventricular tachyarrhythmias. After discharge she returned with identical symptoms, which were now interpreted as intentional intoxication in a suicide attempt. She was referred to the Psychiatry department. The second patient was a 2-year-old boy who had cutaneous exposure to Aconite. Except for some red spots around his mouth there were no other symptoms. The third patient was a 34-year-old woman who ate Monkshood, which she mistook for parsley. Alarmed by the bitter taste she contacted the hospital. She was treated with stomach lavage which removed most of the ingested plant material, and with activated charcoal. She had no symptoms during observation in the hospital. Aconite alkaloids are known to cause ventricular arrhythmia by a prolonged activation of sodium channels. Because there is no antidote, treatment is largely supportive but serious arrhythmias and respiratory arrest need to be anticipated.

    To test the hypothesis that thinner rigid gas permeable (RGP) contact lenses provide superior initial comfort, RGP lenses of 3 center thicknesses, 0.08, 0.12, and 0.16 mm, in otherwise matched parameters, were worn for 30 min by 17 unadapted subjects in a controlled, double masked, randomized study. Comfort ratings (0 to 100) after 30 min of wear were 42 +/- 30, 55 +/- 27, and 57 +/- 28 for the 0.08-, 0.12-, and 0.16-mm thick lenses, respectively (p = 0.04, multiple analysis of variance (MANOVA)), and 93 +/- 13 for the hydrogel control lens. The thinnest RGP lens was significantly less comfortable than its thicker counterparts (p = 0.03, Univariate F-test). There were no differences among the test lenses in edge shape, front surface wettability, or static lens fittings, and small differences in movement, vertical decentration, and front surface geometry were not significantly related to comfort. We hypothesize that the greater flexibility of the thinnest lens resulted in greater deformation of the lens during a blink cycle, causing transient peripheral lens lifting and interaction with the upper eyelid, thereby reducing comfort. In conclusion we found that thinner RGP lenses do not provide an initial comfort advantage and that very thin and, as a corollary, very flexible, RGP lenses can actually be less comfortable initially than stiffer, but otherwise matched, designs.

    Because of an error in the manufacture of digoxin tablets a large number of patients took tablets that contained 0·20 mg. of digitoxin and 0·05 mg. of digoxin instead of the prescribed 0·25 mg. of digoxin. The symptoms are described of 179 patients who took these tablets and suffered from digitalis intoxication. Of these patients, 125 had taken the faultily composed tablets for more than three weeks. In 48 patients 105 separate disturbances in rhythm or in atrioventricular conduction were observed on the electrocardiogram. Extreme fatigue and serious eye conditions were observed in 95% of the patients. Twelve patients had a transient psychosis. Extensive ophthalmological observations indicated that the visual complaints were most probably caused by a transient retrobulbar neuritis. PMID:5273245

  15. Alcohol intoxication: Ion channels and genetics

    1989-04-01

    Acute in vitro exposure to ethanol and other intoxicant-anesthetics activates {gamma}-aminobutyric acid (GABA)-stimulated chloride channels and inhibits voltage-dependent calcium and sodium channels of isolated brain membranes. The question of whether these neurochemical actions are responsible for intoxication in vivo has been addressed using animal populations displaying genetic differences in sensitivity to alcohol and benzodiazepine intoxication. These genetic approaches include inbred strains, selected lines, recombinant inbred strains, and heterogeneous stocks. Genetic differences in ion channel function provide strong evidence for a role of the GABA-stimulated chloride channel in ethanol and benzodiazepine intoxication; the role of calcium and sodium channels is less clear.

    Aspirin overdose could lead to intoxication, with the clinical manifestations of vomit, pulmonary edema and severe dyspnea. Stomach washing, emetics and activated charcoal are the common treatments with a limited efficiency for the intoxication. In this study, an active emulsion for aspirin intoxication was prepared with the detoxifying efficiency of 100% in less than 15 min, with the conditions of dodecane used as the oil phase, 8% Abil EM90 as the surfactant and 0.1 mol/L sodium hydroxide as the inner aqueous phase in a volume ratio of 2 between internal aqueous phase and the oil phase.

    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.

    We report a case of an adult patient using chronic low-dose verapamil who developed severe verapamil intoxication. A 57-year-old male patient was presented at the emergency room after a collapse of unknown etiology. The airway was compromised, and thus, an endotracheal tube was inserted. The patient deteriorated hemodynamically. Because of verapamil use and bradycardia, verapamil intoxication was suspected. The treatment was supported with intravenous fluids, calcium, inotropes, and a transvenous pacemaker. The patient progressively developed circulatory shock. Verapamil intoxication was confirmed, and therapy was adjusted accordingly. Insulin and calcium infusion were intensified, and glucagon and Intralipid® infusion were initiated. With this therapy, the patient's condition improved rapidly. We found different factors in this patient that could have precipitated this event such as diminished metabolism by cytochrome P450 iso-enzymes, a slightly diminished renal function with hypoalbuminemia, and interaction with other protein-binding drugs.

    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{sub 2} (2 mg Cd/kg per day) for 3 weeks. Cd intoxication resulted in a significant reduction in V{sub max} of Na{sup +}/H{sup +} antiport with no changes in K{sub 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{sup +}/H{sup +} 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{sup +}-HCO{sub 3}{sup -} cotransporter-1 (NBC1) in whole kidney membrane fractions was slightly attenuated, whereas that of the Na{sup +}-K{sup +}-ATPase {alpha}-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.

    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.

  3. Histamine, histamine intoxication and intolerance.

    PubMed

    Excessive accumulation of histamine in the body leads to miscellaneous symptoms mediated by its bond to corresponding receptors (H1-H4). Increased concentration of histamine in blood can occur in healthy individuals after ingestion of foods with high contents of histamine, leading to histamine intoxication. In individuals with histamine intolerance (HIT) ingestion of food with normal contents of histamine causes histamine-mediated symptoms. HIT is a pathological process, in which the enzymatic activity of histamine-degrading enzymes is decreased or inhibited and they are insufficient to inactivate histamine from food and to prevent its passage to blood-stream. Diagnosis of HIT is difficult. Multi-faced, non-specific clinical symptoms provoked by certain kinds of foods, beverages and drugs are often attributed to different diseases, such as allergy and food intolerance, mastocytosis, psychosomatic diseases, anorexia nervosa or adverse drug reactions. Correct diagnosis of HIT followed by therapy based on histamine-free diet and supplementation of diamine oxidase can improve patient's quality of life.

  4. Profound Hypoglycemia with Ecstasy Intoxication

    Carrera, Perliveh; Iyer, Vivek N.

    2015-01-01

    Background. 3,4-Methylenedioxymethamphetamine (MDMA) or ecstasy is a synthetic drug that is commonly abused for its stimulant and euphoric effects. Adverse MDMA effects include hyperthermia, psychomotor agitation, hemodynamic compromise, renal failure, hyponatremia, and coma. However, endogenous hyperinsulinemia with severe persistent hypoglycemia has not been reported with MDMA use. Case Report. We report the case of a 29-year-old woman who remained severely hypoglycemic requiring continuous intravenous infusion of high-dose dextrose solutions for more than 24 hours after MDMA intoxication. Serum insulin and C-peptide levels confirmed marked endogenous hyperinsulinemia as the cause of the severe hypoglycemia. Why Should an Emergency Physician Be Aware of This? Immediate and frequent monitoring of blood glucose should be instituted in patients presenting with MDMA ingestion particularly if found to be initially hypoglycemic. Early recognition can help prevent the deleterious effects of untreated hypoglycemia that can add to the morbidity from MDMA use. Clinicians need to be aware of this side effect of MDMA so they can carefully monitor and treat it, especially in patients presenting with altered mental status. PMID:25692049

    Tianeptine (Stablon), although structurally similar to tricyclic antidepressants, acts by enhancing the reuptake of serotonin. A fatal case is presented involving a 26-year-old man, found lying in bed with a "mushroom of foam" around his mouth. Empty blister packs of Stablon and a suicide note were found next to the body. A liquid-liquid extraction procedure with n-hexane: ethyl acetate and n-hexane: 2-propanol, followed by LC-DAD-MS analysis, using positive mode electrospray ionization was performed. The detection limit was 0.001 microg/mL. The toxicological results revealed the following tianeptine concentrations in the post-mortem samples: blood 5.1 microg/mL; urine 2.0 microg/mL; liver 23 microg/g; stomach contents 22 mg. Femoral blood analyses also revealed an ethanol concentration of 0.53 g/L. The present method was also developed and validated for the other post-mortem specimens, since no previous published data had confirmed the post-mortem distribution of tianeptine. The absence of other suitable direct causes of death (macroscopic or histological) and the positive results achieved with the toxicological analysis led the pathologist to rule that death was due to an intoxication caused by the suicidal ingestion of tianeptine in combination with alcohol.

    This experiment evaluated effects following chronic toxicity with 20 ppm fenvalerate (synthetic pyrethroid), 2 ppm monocrotophos (organophosphate) and 2 ppm endosulfan (chlorinated hydrocarbon) on bone health of broiler chicks. A total of 120 chicks were divided equally into 4 groups and were fed poultry mash without (control) or mixed with different pesticides for 8 weeks. Body mass, serum calcium and phosphorus levels were unaffected due to pesticides treatment. However, increase an (p < 0.01) in serum alkaline phosphatase activity was noted and serum total protein decreased (p < 0.01) in all treated groups. Roentogenography revealed destructive changes in the upper part of the femur in the monocrotophos group. Endosulfan intoxicated chicks had increased numbers of trabeculae in the medullary cavity. Microscopic alterations of the costochondral junction in intoxicated chicks were similar. The zones of proliferating, maturing and degenerating, and calcifying cartilage cells were reduced in width and the metaphysis in treated birds showed a reduced number of cartilage cells and thinner trabeculae. Due to toxicity, the capillary scaffolding of the degenerating cartilage cells was reduced and a larger number of transverse trabeculae could be seen in the metaphysis. Appositional bone growth studied by the tetracyclicline labeling technique indicated decreased active osteons.

  7. PROTEOSE INTOXICATIONS AND INJURY OF BODY PROTEIN

    PubMed Central

    Whipple, G. H.; Van Slyke, Donald D.

    1918-01-01

    The acute intoxication following an injection of a toxic proteose is usually associated with a large increase (40 per cent or more) in the non-protein nitrogen of the blood. This increase is found chiefly in the blood urea nitrogen, but the amino and peptide nitrogens also may show small increases. The changes observed in the blood non-protein nitrogen are identical with those which follow the feeding of large amounts of meat (8). These facts indicate that the proteose intoxication causes an abnormally rapid autodigestion of tissue proteins, but that the nitrogenous end-products are, in chief part at least, the same that result from normal catabolism of food proteins. There is no evidence that the autolytic products play any part in causing the intoxication. The possibility of such a part and a resultant vicious circle is not excluded, but from the available facts the autolysis appears more as a result rather than cause of the intoxication. It appears possible that in disease or intoxication tissue catabolism may be enormously accelerated and yet yield the end-products of normal protein metabolism. PMID:19868251

    Background: Despite the known adverse effects of lambda cyhalothrin insecticide, little is known about its hepatopancreatic intoxication effects. The present study was carried out to elucidate sub-chronic effect of Karat 2.5% EC formulation of lambda cyhalothrin on male albino rats. Methods: To explore the effects of exposure to lambda cyhalothrin on rats and its mechanism, low (1/40 of LD50, 5 mg/kg/day) and high dose (1/4 of LD50, 50 mg/kg/day) lambda cyhalothrin were applied to rats via drinking water for 3 months. Blood samples were collected monthly, and the animals were dissected for liver and pancreas’s examination at the end of the experiment. Lambda cyhalothrin administration was associated with the elevation in lipid peroxidation marker, malondialdehyde (MDA), reduction in SH-protein a major marker for antioxidant, as well as basel paraoxonase (PON) in both treated groups throughout the experimental periods. Results: In addition, significant elevations in liver enzymes alanin amino transferase, (ALT), and aspartate amino transferase (AST), as well as plasma acetylcholinesterase (AChE) and glucose level. While, significant reduction in insulin level through the experimental periods. Results of histopathological and histochemical studies showed that lambda cyhalothrin exposure induces liver and pancreatic tissues damage and depletion in glycogen content was pronounced in liver of both treated groups. Conclusions: In conclusion subchronic intoxication with lambda cyhalothrin formulation induced remarkable changes in the examined parameters. PMID:26221269

    2011-01-01

    Background: Aluminum Phosphide or rice tablet is one of the most common pesticides which leads to accidental or intentional acute intoxication and finally death. In this paper, we describe a successful management of intoxication with rice tablet in a young girl. Case Presentation: A 14-year-old girl was admitted due to consumption of rice tablet. Gastric washing with two vials of sodium bicarbonate and discharge suction was done. In the first 24 hours, the patient underwent recurrent hydration, dopamine infusion with sodium bicarbonate, calcium, magnesium and amiodarone. On the second day of admission, the patient was transferred to intensive care unit (ICU) and five days later, she was discharged without liver or renal complications. Conclusion: Short interval between consumption of this tablet and start of the treatment and on time rescue to the patient can be some of the important factors to prevent early death in intoxication with this tablet.

    The association between vitamin D deficiency and increased risk of, among others, cardiovascular and autoimmune diseases has lead in the last years to an enhanced interest in the usage of supplements to achieve the normalization of plasmatic values at 25(OH) D. Apparently this search for normalization is resulting in an higher incidence on vitamin D intoxication. We present the case of an 81 years old woman with metabolic encephalopathy and renal failure secondary to iatrogenic vitamin D intoxication. Calcium and vitamin D oral supplements were prescribed after an osteoporotic vertebral fracture. The patient improved clinically as well as analytically after receiving treatment with diuretics and hydration. We emphasize the importance of discarding hypercalcemia as a cause of metabolic encephalopathy; moreover we highly recommend keeping vitamin D intoxication in mind as an uncommon although always possible etiology of reversible hypercalcemia and renal failure.

    2005-01-01

    Background: Irrigation of closed body spaces may lead to substantial perioperative fluid and electrolyte shifts. A syndrome occurring during transurethral resection of prostate (TURP), and a similar syndrome described in women undergoing transcervical endometrial ablation (TCEA) are both characterised by a spectrum of symptoms which may range from asymptomatic hyponatraemia to convulsions, coma, and death. Such potentially serious consequences require prompt recognition and appropriate management of this "water intoxication" syndrome. Objectives: To examine the role of a previously described core algorithm "COVER ABCD–A SWIFT CHECK", supplemented by a specific sub-algorithm for water intoxication, in the management of this syndrome occurring in association with anaesthesia. Methods: The potential performance of this structured approach for each of the relevant incidents among the first 4000 reported to the Australian Incident Monitoring Study (AIMS) was compared with the actual management as reported by the anaesthetists involved. Results: From the first 4000 incidents reported to AIMS, 10 reports of water intoxication were identified, two from endometrial ablations under general anaesthesia and eight from male urological procedures under spinal anaesthesia. The "core" crisis management algorithm detected a problem in seven cases; however, it was deficient in dealing with neurological presentations. Diagnosis of the cause of the incident would have required a specific water intoxication sub-algorithm in eight cases and a hypotension algorithm in a further two cases. Corrective strategies also required a specific sub-algorithm in eight cases, while the hypotension and cardiac arrest sub-algorithms were required in conjunction with the water intoxication sub-algorithm in the remaining two. Conclusion: This relatively uncommon problem is managed poorly using the "core" crisis management sub-algorithm and requires a simple specific sub-algorithm for water

    Deaths of individuals being arrested are important and complex medicolegal cases. Conclusions regarding the cause and manner of death for such cases must take into account multiple factors that may have played a role, as well as anticipate the forensic issues that will arise. In this article, we review the deaths of 2 individuals in which phencyclidine intoxication was a factor that contributed to death during arrest. Most cases of sudden death during arrest have involved cocaine intoxication; because phencyclidine's pharmacologic properties are quite different from those of cocaine, these cases allow for comparisons to those factors that may have greater importance.

    Excessive water drinking is a recognised feature of schizophrenia. We present here a case of excessive water drinking precipitated by acute psychological stress. A 52-year-old woman, with no previous mental health problems, was found in a state of altered consciousness and was profoundly hyponatraemic. She had consumed excess amount of water due to severe mental stress. She was treated with hypertonic saline followed by fluid restrictions. The water intoxication had caused brain damage which led to behavioural changes and impaired cognition. We describe the pathophysiology of water intoxication.

    Because ethanol elicits a dose-dependent hydrolysis of brain sialogangliosides, the authors tested the possibility that injected gangliosides might antagonize intoxicating doses of ethanol. Clear anti-intoxication effects were seen at 24 hr post-injection of mixed mouse-brain gangliosides at 125-130 mg/kg, but not at lower or higher doses. Sleep time was reduced on the order of 50%, and roto-rod agility was significantly enhanced. Sialic acid (SA) similarly antagonized ethanol; however, the precursor of SA, N-acetyl-D-mannosamine, as well as ceramide and asialoganglioside did not.

  6. Acute intoxication with guaifenesin, diphenhydramine, and chlorpheniramine.

    PubMed

    Wogoman, H; Steinberg, M; Jenkins, A J

    1999-06-01

    Mixed drug reactions are frequently encountered in emergency department overdose cases and also in fatal intoxications. Assessment of the relative contribution of each drug in producing adverse effects is often compounded by lack of case history and the paucity of cases reported in the literature. This report describes a fatal intoxication with three common over-the-counter medications: guaifenesin, diphenhydramine, and chlorpheniramine. A 48-year-old woman was found dead in the attic bedroom of her residence. Specimens obtained at autopsy for toxicologic analysis included heart blood, urine, bile, gastric contents, vitreous humor, and cerebrospinal fluid. The over-the-counter drugs were identified and quantitated by acid/neutral or basic liquid-liquid extraction followed by gas chromatographic analysis with nitrogen phosphorus detection. Concentrations of guaifenesin, diphenhydramine, and chlorpheniramine detected in the heart blood were 27.4, 8.8, and 0.2 mg/L, respectively. The cause of death was determined to be acute intoxication by the combined effects of guaifenesin, diphenhydramine, and chlorpheniramine, and the manner of death was determined to be suicide. To our knowledge, the blood guaifenesin concentration in this case is the highest reported concentration to date associated with an acute intoxication.

  7. Recognition of intoxication by alcohol counselors.

    Recent studies have found that police officers, bartenders, social drinkers, and trained interviewers are often unable to recognize when others are intoxicated. The present two studies were conducted to evaluate: (a) the recognition ability of alcohol counselors compared to mental health counselors, and (b) the recognition ability of less-experienced versus more-experienced alcohol counselors. Subjects viewed four videotapes of a 21-year-old male engaged in simulated counseling interviews after he was given drinks containing alcohol to achieve one of four target Blood Alcohol Level (BAL) goals: .00%, .05%, .10%, .15%. Results indicated that alcohol counselors were not uniformly more accurate than mental health therapists, nor were more-experienced alcohol counselors uniformly more accurate than less-experienced alcohol counselors at recognizing intoxication or estimating BAL. In addition, subjects generally underestimated the target's sober-intoxicated status and BAL when he was given alcohol, but almost every subject recognized that the target was at least moderately intoxicated when his BAL was .15%.

    Nylon bags are used for packaging fire debris in several countries, particularly in Europe. The possibility of cross-contamination during transport from the fire scene to the laboratory, in normal casework conditions in the U.K., was studied for two brands of nylon bags, using simulated heavy-loaded fire debris. Three experiments were carried out with each brand, using as sample a piece of cotton fabric soaked with gasoline. One experiment was carried out using automotive paint thinner (oxygenated solvent). Each sample was sealed in a nylon bag and stored in contact with eight empty bags. The empty bags were analysed at regular intervals for a period of time up to 8 weeks, using SPME and GC/MS. Cross-contamination was found for components of gasoline (toluene and C2 -alkylbenzenes) in the two brands of nylon bags used, after 4 days and 2 weeks. Cross-contamination using automotive topcoat thinner was detected after 2 days.

  10. Acute barium nitrate intoxication treated by hemodialysis.

    2005-01-01

    A 22-year-old male was admitted to hospital with diarrhea and vomiting, cardiac arrhythmias, severe hypokalemia and gradual onset of muscular weakness. A potassium infusion was started, but for several hours serum potassium remained low. Evidence of toxic ingestion was initially lacking. When it became clear -- after a considerable delay -- that the patient had ingested barium nitrate, hemodialysis was started. This resulted in rapid clinical improvement with correction of hypokalemia and restored muscular function. Intoxication with barium causes hypokalemia, arrhythmias, muscular weakness and paralysis, often requiring respiratory support. This patient presented with symptoms typical of severe barium intoxication, non-responsive to potassium supplementation. There are few published reports on the use of hemodialysis in barium poisoning. This case confirms the possible benefit of hemodialysis in severe cases, where potassium supplementation alone is insufficient.

    Synthetic cannabinoids are relatively new substances of abuse. Recently, abuse of synthetic cannabinoids has been increasingly reported in the lay press and medical literature. When new compounds are introduced, their use is initially not restricted by prohibition therefore their consumption cannot be verified by standard drug tests. The use of these compounds among adolescents and young adults is constantly growing, making it important for emergency services to be familiar with the signs and symptoms of intoxication present. Overdose and chronic use of these substances can cause adverse effects including altered mental status, tachycardia, and loss of consciousness. Here, we report five cases of acute intoxication by synthetic cannabinoids 5F-ADB and MMB-2201 with analytical confirmation.

    Objective The incidence of accidental or suicidal ingestion of methyl alcohol is high and methyl alcohol intoxication has high mortality. Methyl alcohol intoxication causes severe neurological sequelae and appears to be a significant problem. Methyl alcohol causes acute metabolic acidosis, optic neuropathy leading to permanent blindness, respiratory failure, circulatory failure and death. It is metabolised in the liver, and its metabolite formic acid has direct toxic effects, causing oxidative stress, mitochondrial damage and increased lipid peroxidation associated with the mechanism of neurotoxicity. Methanol is known to cause acute toxicity of the central nervous system; however, the effects on peripheral neuromuscular transmission are unknown. In our study, we aimed to investigate the electrophysiological effects of experimentally induced acute methanol intoxication on neuromuscular transmission in the early period (first 24 h). Methods After approval by the Animal Experiment Ethics Committee of Ege University, the study was carried out on 10 Wistar rats, each weighing about 200 g. During electrophysiological recordings and orogastric tube insertion, the rats were anaesthetised using intra-peritoneal (IP) injection of ketamine 100 mg kg−1 and IP injection of xylazine 10 mg kg−1. The rats were given 3 g kg−1 methyl alcohol by the orogastric tube. Electrophysiological measurements from the gastrocnemius muscle were compared with baseline. Results Latency measurements before and 24 h after methanol injection were 0.81±0.11 ms and 0.76±0.12 ms, respectively. CMAP amplitude measurements before and 24 h after methanol injection were 9.85±0.98 mV and 9.99±0.40 mV, respectively. CMAP duration measurements before and 24 h after methanol injection were 9.86±0.03 ms and 9.86±0.045 ms, respectively. Conclusion It was concluded that experimental methanol intoxication in the acute phase (first 24 h) did not affect neuromuscular function. PMID:27366524

  13. Fatal intoxication with hydrocarbons in deltamethrin preparation.

    PubMed

    2009-12-01

    Pyrethroid insecticides are very widely used in agriculture and household due to high effectiveness and low toxicity to humans. We have described a case of a fatal oral intoxication with decis, the insecticide containing pyrethroid (deltamethrin) in a hydrocarbon base. Pyrethroids, including deltamethrin, undergo rapid biotransformation by liver enzymes, which limit their systemic toxicity. Thus, we assume that in the presented case, fatal outcome of poisoning with decis was rather connected with toxic effects of hydrocarbon base (solvent naphtha) than with deltamethrin action. In the described case, detection of aromatic hydrocarbons in blood and lung tissue and their metabolites in urine confirms that these substances were absorbed from gastrointestinal tract to the systemic circulation. Predominant among the clinical outcomes in our patient was profound depression of CNS with apnea, which could be connected with narcotic action of organic solvents. The cardiac arrest was in mechanism of asystolia with prior non-responsive to catecholamines bradycardia and vascular collapse. We connect it with hydrocarbon-induced cardiotoxicity. It is worth remembering that many pyrethroid-containing insecticides are formulated in a hydrocarbon base. Intoxication with such preparations should always be considered not only as poisoning with pyrethroid alone but also as intoxication with hydrocarbons.

  14. Interstitial Pulmonary Edema Following Bromocarbamide Intoxication

    1974-01-01

    Bromocarbamides are sleep-inducing drugs which can lead, in man, to intoxication and death due to respiratory failure. To prove whether hemodynamic factors or the changed endothelial permeability induce pulmonary edema, animal experiments were performed. The fine structural changes in pulmonary edema in rabbits were observed at 60, 90 and 120 minutes after oral administration. The major findings were a) large blebs between capillary endothelium and alveolar epithelium and b) interstitial edema of the vessel wall. The bleb contents were much less electron dense than the blood contents in the capillary. Colloidal carbon did not enter the bleb or the edematous interstitial tissue. Exogenous peroxidase uptake in pinocytotie vesicles increased in pathologic cases. The hemodynamic measurements in animal receiving artificial respiration which maintained the blood pO2 at a steady state showed similar blebs in the pulmonary vessels, indicating that anoxia is not the major cause of the vascular lesion. Moreover, pulmonary arterial pressure and pulmonary vascular resistance could be held in the normal range in artificially respirated animals under bromocarbamide intoxication. Thus, hemodynamic factors are not likely to play a pathogenetic role in bringing about pulmonary edema. The chief, early factor is the increased endothelial permeability due to increased cytoplasmic transport. From this a practical suggestion for treating patients with bromocarbamide intoxication is derived: the usual fluid replacement in shock patients should be handled with great care to avoid fluid overload of the lung.

  18. Spirituality, intoxication and addiction: six forms of relationship.

    PubMed

    Room, Robin

    2013-09-01

    The paper considers six connections between spirituality and intoxication or addiction. They are: intoxication as a means of communication with a spiritual world; intoxication as destroying spirituality; shared use and intoxication as creating and validating community; spirituality and religion as a means of collective sobering-up; spirituality in individual sobering up; and abstinence as a spiritual practice, a witness, or a badge of membership in a spiritual community. Intoxication can either enhance or impede spirituality, both at individual and collective levels. Spirituality is often important in sobering up, both individually and collectively, and abstinence is a part of spiritual or religious practice in some traditions. But a full account must acknowledge the diversity in the interactions of spirituality and intoxication or addiction.

    Cyanide is a chemical widely used in industry, and is a major environmental pollutant. Its toxicity is caused by inhibition of cytochrome oxidase resulting in histotoxic hypoxia. The effect of sublethal doses of cyanide on memory and hippocampal neurotransmitters was studied in male Wistar strain albino rats. Cyanide reduced the memory along with reduction in the levels of dopamine and 5-hydroxytryptamine in the hippocampus. Pre-existing malnutrition in the animals exaggerated these effects.

    Purpose To assess retinal nerve fiber layer (RNFL) thickness at term-equivalent age in very preterm (<32 weeks gestational age) versus term-born infant cohorts, and compare very preterm infant RNFL thickness with brain anatomy and neurodevelopment. Design Cohort study. Methods RNFL was semi-automatically segmented (one eye per infant) in 57 very preterm and 50 term infants with adequate images from bedside portable, handheld spectral domain optical coherence tomography (Bioptigen, Inc., Research Triangle Park, NC) imaging at 37-42 weeks postmenstrual age. Mean RNFL thickness was calculated for the papillomacular bundle (−15° to + 15°) and temporal quadrant (−45° to +45°) relative to the fovea-optic nerve axis. Brain magnetic resonance imaging (MRI) scans clinically obtained in 26 very preterm infants were scored for global structural abnormalities by an expert masked to data except for age. Cognitive, language, and motor skills were assessed with Bayley Scales of Infant and Toddler Development-III (Pearson, San Antonio, TX) in 33 of the very preterm infants at 18-24 months corrected age. Results RNFL was thinner for very preterm versus term infants at the papillomacular bundle ([mean ± standard deviation] 61 ± 17 versus 72 ± 13 μm, p<0.001) and temporal quadrant (72 ± 21 versus 82 ± 16 μm, p=0.005). In very preterm infants, thinner papillomacular bundle RNFL correlated with higher global brain MRI lesion burden index (R2=0.35, p=0.001) and lower cognitive (R2=0.18, p=0.01) and motor (R2=0.17, p=0.02) scores. Relationships were similar for temporal quadrant. Conclusions Thinner RNFL in very preterm infants relative to term-born infants may relate to brain structure and neurodevelopment. PMID:26386157

    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.

    Datura stramonium is a toxic plant member of the Solanaceae family. Its consumption may result in severe anticholinergic toxicity. We report the intoxication of 5- and 4-year-old brothers with Datura stramonium, which presented in two different manners. The first child presented agitation, hallucination and mydriasis that improved rapidly with benzodiazepine medication. The second presented comatose, mydriasis and Babinski signs. Gastric lavage and activated charcoal administration were performed. The child was intubated and mechanically ventilated until consciousness improvement. Datura stramonium poisoning may be considered by physicians in case of acute onset of decreased consciousness or behaviour trouble associated with anticholinergic signs and symptoms.

    After recalling the risks deriving from alcohol abuse at work, the paper discusses the complex problems (medical, social, juridical) related to drinking and driving. Acute intoxication may be adequately identified (also in the medico-legal setting) through direct or indirect measurement of blood ethanol concentration, whereas the diagnosis of alcohol abuse and binge drinking (useful to assess fitness to work and/or driving) is complicated by the scarce efficiency of the currently available biomarkers. Alcohol abuse control and prevention among Italian Police Forces are ruled by the Ministerial Decree 30 June 2003, n. 198.

    Superwarfarin toxicity may be a serious problem. It needs high clinical suspicious in patients with bleeding diathesis without hematologic or liver diseases even in patients with apparent negative history of warfarin or other anticoagulant accessibility. Here we reported a patient with a negative history of any medical diseases or drug administration who was referred with generalized ecchymosis. Increased international normalized ratio and decreased vitamin K-dependent coagulation factors were detected in this patient. His hematologic and liver evaluations were normal. Clinical pharmacist emphasis in taking history revealed using anticoagulant rodenticide all over the farm the patient lived in that might result in unaware intoxication in this patient who suffered dementia.

    Several long-term effects of alcohol abuse in children and adolescents are well described. Alcohol abuse has severe effects on neurodevelopmental outcome, such as learning disabilities, memory deficits, and decreased cognitive performance. Additionally, chronic alcohol intake is associated with chronic liver disease. However, the effects of acute alcohol intoxication on liver function in children and adolescents are not well characterized. The aim of this study was to determine if a single event of acute alcohol intoxication has short-term effects on liver function and metabolism. All children and adolescents admitted to the Department of Pediatrics and Adolescent Medicine between 2004 and 2011 with the diagnosis "acute alcohol intoxication" were included in this retrospective analysis. Clinical records were evaluated for age, gender, alcohol consumption, blood alcohol concentration, symptoms, and therapy. Blood values of the liver parameters, CK, creatinine, LDH, AP, and the values of the blood gas analysis were analyzed. During the 8-year study period, 249 children and adolescents with the diagnosis "acute alcohol intoxication" were admitted, 132 (53%) girls and 117 (47%) boys. The mean age was 15.3 ± 1.2 years and the mean blood alcohol concentration was 0.201 ± 0.049%. Girls consumed significantly less alcohol than boys (64 g vs. 90 g), but reached the same blood alcohol concentration (girls: 0.199 ± 0.049%; boys: 0.204 ± 0.049%). The mean values of liver parameters were in normal ranges, but AST was increased in 9.1%, ALT in 3.9%, and γGT in 1.4%. In contrast, the mean value of AST/ALT ratio was increased and the ratio was elevated in 92.6% of all patients. Data of the present study showed significant differences in the AST/ALT ratio (p < 0.01) in comparison to a control group. Data of the present study indicate that there might be an effect of acute alcohol intoxication on transaminase levels. The AST/ALT ratio seems to reflect the damage in hepatocytes

    During a two month period, the authors gathered data from patients who visited an emergency ward due to acute intoxication by a household product, and they compared the care which those patients required with the other patients suffering from different intoxications. The variables were introduced and analyzed using a SPSS 75.0 statistics package. The emergency ward registered 281 intoxication incidents of which 22 or 8.7% were related to household products. Among the conclusions drawn from this study the authors emphasize that the majority of patients intoxicated by household products were women. Caustic products are involved in the greatest number of incidences, either accidentally swallowed, splashed into eyes or inhaled as gas. The amount of treatment those patients require is less than the treatment required for other intoxications. Their prognostic is good.

    A dramatic response was noted in a patient at our hospital who received hemodialysis therapy for severe acidosis secondary to an unknown toxin, subsequently identified as cyanide. We were unable to find any information concerning the hemodialysis clearance and extraction ratio of cyanide; thus, we studied the effect of hemodialysis in dogs receiving a constant infusion of cyanide with and without a simultaneous infusion of thiosulfate. The hemodialysis clearance of cyanide in the presence of thiosulfate was 38.3 +/- 5.4 ml/min with an extraction ratio of 0.43 +/- 0.06 (n = 4). Hemodialysis was found to increase the lethal dose of cyanide without thiosulfate infusion, and a further increase was noted with the thiosulfate infusion. Thiosulfate promotes mitochondrial metabolism of cyanide to thiocyanate. The end product, thiocyanate, is quickly removed by hemodialysis. We believe that the demonstrated effectiveness of hemodialysis in the treatment of acute cyanide intoxication is related not only to the hemodialysis clearance of cyanide, but also to the removal of its metabolic end product, thiocyanate. Based on our observations, we feel that hemodialysis is an effective adjunct in the treatment of acute cyanide intoxication.

    We report a case of a 66-year-old patient with paraquat intoxication resulting in the requirement for hemoperfusion, hemodialysis, and plasma exchange. His initial serum paraquat level was 0.24 µg/mL (0.0-0.1 µg/mL). Activated charcoal (50 g) was administered orally, and high-dose N-acetylcysteine (150 mg/kg) was administered intravenously. In addition, immediate 4 h hemoperfusion was also performed for three consecutive days after admission. Hemodialysis was started on the 4th day after admission because of uremia. On the 9th day after admission, laboratory findings demonstrated hemolytic uremic syndrome (HUS): microangiopathic hemolytic anemia (MAHA), thrombocytopenia, elevated reticulocyte count, and lactate dehydrogenase (LDH). Plasma exchange was performed three times consecutively. Anemia and thrombocytopenia were improved, and LDH was normalized after plasma exchange. Urine output increased to 2240 mL/day on the 18th day after admission, and hemodialysis was discontinued. He is currently being observed at our follow-up clinic without renal impairment or pulmonary dysfunction for 1.5 years since discharge. We should suspect paraquat-associated HUS when thrombocytopenia and anemia are maintained for a long time after paraquat intoxication.

    In Mozambique, epidemics of the cassava-associated paralytic disease, konzo, have been reported in association with drought or war: over 1100 cases in 1981, over 600 cases in 1992-1993, and over 100 cases in 2005. Smaller epidemics and sporadic cases have also been reported. Large epidemics have occurred at times of agricultural crisis, during the cassava harvest, when the population has been dependent on a diet of insufficiently processed bitter cassava. Konzo mostly affects women of child-bearing age and children over 2 years of age. When measured, serum or urinary thiocyanate concentrations, indicative of cyanide poisoning, have been high in konzo patients during epidemics and in succeeding years. Monitoring of urinary thiocyanate concentrations in schoolchildren in konzo areas has shown persistently high concentrations at the time of the cassava harvest. Inorganic sulphate concentrations have been low during and soon after epidemics. Programmes to prevent konzo have focused on distributing less toxic varieties of cassava and disseminating new processing methods, such as grating and the flour wetting method. Attention should be given to the wider question of agricultural development and food security in the regions of Africa where dependence on bitter cassava results in chronic cyanide intoxication and persistent and emerging konzo.

  8. Polyneuropathy induced by n-hexane intoxication in Taiwan.

    PubMed

    Huang, Chin-Chang

    2008-03-01

    n-Hexane and methyl n-butyl ketone share a common metabolite, 2,5-hexanedione, a potent neurotoxin. Neurotoxic effects to both peripheral and central nervous systems may occur after occupational exposure or recreational abuse of n-hexane. Initial clinical manifestations include numbness and tingling sensation in the toes and fingers, followed by progressive weakness and areflexia, particularly in the distal limbs. Chronic low-dose n-hexane exposure, often observed in industrial workers, apparently causes axonal loss with sensory impairment. Subacute high-dose n-hexane exposure, often observed in glue-sniffers, can cause axonal swelling and secondary demyelination with muscle wasting and weakness. Electrophysiological studies demonstrate prominent prolongation of distal latencies, slowing of nerve conduction velocities, and conduction block with temporal dispersion particularly in severely intoxicated patients. Pathological hallmarks include giant axonal swelling with secondary demyelination and relative loss of large myelinated fibers. Giant axons are accumulated by 10 nm neurofilaments. The clinical course tends to be biphasic with "coasting" for 2-3 months, followed by a slow recovery for about 1-2 years after cessation of exposure to n-hexane. Prognosis is usually favorable. Severely affected patients may develop sequelae of muscle wasting, foot drop, and spasticity. Increased awareness of the n-hexane neurotoxicity in industrial workers and glue sniffers as well as use of safe solvents and adequate ventilation systems are important for preventing n-hexane toxicity.

    Sivakumar, S.; Khatiwada, Chandra Prasad; Sivasubramanian, J.

    The present study was designed to examine the protective effects of the chelating agents desferrioxamine (DFO) and deferiprone (DFP) in aluminum intoxicated spleen tissue of mice by Fourier transform infrared (FTIR) spectroscopy. The finding revealed the alterations on the major biochemical constituents, such as lipids, proteins, phosphodiester and nucleic acids of the spleen tissue of mice at molecular level. The significant decreased in the peak areas of asymmetric and symmetric mode of the phosphodiester groups from control to aluminum intoxicated, but improved it by DFP and DFO + DFP treatments respectively for nearer control value. The bands ratio at I1081/I1232 significantly decreased from control to aluminum, but enhanced it by DFP and DFO + DFP respectively. This result suggests that DFO and DFP are the phosphodiesterase inhibitor, recovered from chronic growth of diseases in the spleen. Amide I and amide II peak area values decreased from control to aluminum intoxicated spleen tissue, but treated with DFP and DFO + DFP significantly improved. This result suggests an alteration in the protein profile. The absence of Olefinicdbnd CH stretching in aluminum intoxicated spleen suggests an altered lipid levels. Concentrations of trace elements were found by ICP-OES. Histopathological findings confirmed the biochemical observations of this study. The results of the FTIR study were found to be in agreement with biochemical studies and demonstrated that FTIR can be used successfully applied to toxicological studies at molecular level.

    We reported the case of a 70-year-old woman with moderate renal failure due to anti-neutrophil cytoplasmic antibody-related glomerulonephritis who developed symptomatic water intoxication (serum Na: 108 mEq/L) following treatment with oral low-dose cyclophosphamide (CY) (50mg/day). Estimated glomerular filtration rate was 29.5 mL/min/1.73 m(2). She had drunk >2 L of fluid in 12 h prior to the development of cerebral oedema. This rare case suggests that oral low-dose CY could be an occult cause of water intoxication in patients with chronic kidney disease taking large fluid volumes.

    The vitamin B-complex deficiency increases the vulnerability to neuro- and systemic toxicity of Pb in young rats. Thus, the nutritional status of vitamins like that of protein or minerals seems to influence the etiology of Pb toxicity and may be expected to affect the response toward Pb chelators. 2,3 dimercaptosuccinic acid (DMSA) and N-(2-hydroxyethyl) ethylene-diamine triacetic acid (HEDTA) have been found to be effective antidotes to Pb intoxication. In the present study, these selective metal chelating agents were compared for their ability to reduce the body burden of Pb and restore the altered biochemical parameters in young developing Pb intoxicated rats maintained on normal or vitamin B-complex deficient diet. The investigation was aimed to suggest suitable prophylaxis of Pb poisoning prevalent among children who may also be suffering from vitamin deficiency in developing and poor countries.

  12. Drugs of abuse: management of intoxication and antidotes.

    PubMed

    Montoya, Ivan D; McCann, David J

    2010-01-01

    Illicit drug intoxications are an increasing public health problem for which, in most cases, no antidotes are clinically available. The diagnosis and treatment of these intoxications requires a trained clinician with experience in recognizing the specific signs and symptoms of intoxications to individual drugs as well as polydrug intoxications, which are more the rule than the exception. To make the diagnosis, the clinical observation and a urine toxicology test are often enough. Evaluating the blood levels of drugs is frequently not practical because the tests can be expensive and results may be delayed and unavailable to guide the establishment of a treatment plan. Other laboratory tests may be useful depending on the drug or drugs ingested and the presence of other medical complications. The treatment should be provided in a quiet, safe and reassuring environment. Vital signs should be closely monitored. Changes in blood pressure, respiratory frequency and temperature should be promptly treated, particularly respiratory depression (in cases of opiate intoxication) or hyperthermia (in cases of cocaine or amphetamine intoxication). Intravenous fluids should be administered as soon as possible. Other psychiatric and medical complication should receive appropriate symptomatic treatment. Research on immunotherapies, including vaccines, monoclonal and catalytic antibodies, seems to be a promising approach that may yield specific antidotes for drugs of abuse, helping to ameliorate the morbidity and mortality associated with illicit drug intoxications.

    Abstract Emerging evidence suggests that a history of sports-related concussions can lead to long-term neuroanatomical changes. The extent to which similar changes are present in young athletes is undetermined at this time. Here, we tested the hypothesis that collegiate football athletes with (n = 25) and without (n = 24) a self-reported history of concussion would have cortical thickness differences and altered white matter integrity relative to healthy controls (n = 27) in fronto-temporal regions that appear particularly susceptible to traumatic brain injury. Freesurfer software was used to estimate cortical thickness, fractional anisotropy was calculated in a priori white matter tracts, and behavior was assessed using a concussion behavioral battery. Groups did not differ in self-reported symptoms (p > 0.10) or cognitive performance (p > 0.10). Healthy controls reported significantly higher happiness levels than both football groups (all p < 0.01). Contrary to our hypothesis, no differences in fractional anisotropy were observed between our groups (p > 0.10). However, football athletes with a history of concussion had significantly thinner cortex in the left anterior cingulate cortex, orbital frontal cortex, and medial superior frontal cortex relative to healthy controls (p = 0.02, d = −0.69). Further, football athletes with a history of concussion had significantly thinner cortex in the right central sulcus and precentral gyrus relative to football athletes without a history of concussion (p = 0.03, d = −0.71). No differences were observed between football athletes without a history of concussion and healthy controls. These results suggest that previous concussions, but not necessarily football exposure, may be associated with cortical thickness differences in collegiate football athletes. PMID:26061068

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent.

    In rats treated with sodium cyanide (5-20 mg/kg, ip) dopamine was dose dependently decreased in the striatum within 60 sec. One of the main metabolites of dopamine in the central nervous system, 3-methoxy-4-hydroxyphenylacetic acid (HVA), was decreased in striatum, olfactory tubercle, and hippocampus. However, the oxidatively deaminated metabolite, 3,4-dihydroxyphenylacetic acid (DOPAC), was not significantly altered in any of the brain regions studied. Naturally occurring levels of 3,4-dihydroxy-L-phenylalanine (L-dopa), as well as L-dopa accumulated after inhibition of the neuronal L-aromatic amino acid decarboxylase, increased in cyanide-treated rats. The dopamine receptor antagonist spiperone (0.05 mg/kg, ip) slightly increased the survival in acute cyanide intoxication. Sodium cyanide increased the levels of glutamine in frontal cortex and striatum at all doses studied. Glutamic acid was increased in the cerebellum, striatum, and hippocampus after sodium cyanide (5-10 mg/kg, ip). Higher doses decreased glutamic acid in the cerebellum, the frontal cortex, and the striatum. gamma-Aminobutyric acid (GABA) concentrations were diminished at high doses in all regions studied. Cyanide increased the levels of cyclic GMP in the cerebellum. In the striatum cyclic GMP was decreased after sodium cyanide (10 and 20 mg/kg). No significant alterations in the concentrations of acetylcholine or choline were seen in the striatum of cyanide-treated rats. The acetylcholinesterase inhibitor physostigmine and the muscarinic receptor antagonist atropine decreased the survival of mice given sodium cyanide. Acute cyanide intoxication thus produces rapid and fairly specific changes in central dopaminergic and GABA-ergic pathways.

    A poultry research facility that housed 2400 Peterson x Hubbard cross broilers (48 pens of 50 chicks each) experienced 4% mortality within 24 hr of chick placement. Mortality started within 4 hr of placement, and within 72 hr, cumulative mortality had reached 52%. Mild dyspnea was the only clinical sign noted in some chicks prior to death. The primary gross lesion noted in the chicks submitted was moderate to severe pulmonary congestion. The lungs of four of these chicks sank in formalin, and blood-tinged fluid was noted in the mouth and nares of two chicks. The microscopic lesions noted in the affected chicks were moderate to severe pulmonary edema and congestion. The diagnosis indicated to the submitter was that pulmonary edema caused by exposure to an unidentified noxious gas caused the death of the chicks. The poultry house environment was tested for sulfur dioxide, oxides of nitrogen, carbon monoxide, carbon dioxide, and volatile organic compounds (as produced by combustion engines); all tests were negative for significant levels of these compounds. A second broiler flock was placed in the same facility and the mortality at 6 wk was 11%, which was greater than the 2.5%-4.7% mortality seen in the previous four flocks on the farm. Further investigation revealed that the only change in management practice in this facility prior to the onset of the severe mortality problem was the replacement of 48 heat lamp bulbs (one for each pen). The new heat lamp bulbs were polytetrafluoroethylene (PTFE) coated. PTFE gas intoxication has been reported in several exotic avian species, but this intoxication has not been previously reported in a poultry flock.

    The first case of fatal intoxication due to ingestion of gamma-hydroxybutyric acid (GHB) and intravenous use of heroin is reported. A 42-year-old man, known to have been a heroin addict and to have taken other psychoactive substances, who had been in treatment with GHB for several months, was found dead. Anatomohistopathologic examination showed generalized visceral congestion, edema and pulmonary anthracosis, chronic bronchitis and chronic active hepatitis. Toxicological findings included fluid and tissue distributions of GHB, morphine and 6-monoacetylmorphine. GHB and morphine concentrations were respectively 11.5 and 0.77 micrograms/mL (blood), 84.3 and 0.3 micrograms/mL (vitreous humor), 258.3 and 1.35 micrograms/mL (urine), 57.0 and 14.3 micrograms/mL (bile), 40.0 and 0.43 micrograms/g (brain), 43.0 and 0.60 micrograms/g (liver), 47.0 and 0.68 micrograms/g (kidney). Blood and urine levels of 6-monoacetylmorphine were 28.5 and 12.1 ng/mL respectively. The presumed mechanism of action and pharmacokinetics of GHB are briefly reviewed, with reference to its therapeutic use and to reports of non-fatal GHB intoxication.

    Intravenous lipid emulsion (ILE) is a lifesaving treatment of lipophilic drug intoxications. Not only does ILE have demonstrable efficacy as an antidote to local anesthetic toxicity, it is also effective in lipophilic drug intoxications. Our case series involved 10 patients with ingestion of different types of lipophilic drugs. Intravenous lipid emulsion treatment improved Glasgow Coma Scale or blood pressure and pulse rate or both according to the drug type. Complications were observed in 2 patients (minimal change pancreatitis and probable ILE treatment-related fat infiltration in lungs). In our case series, ILE was used for different lipophilic drug intoxications to improve cardiovascular and neurologic symptoms. According to the results, it was found that ILE treatment is a lifesaving agent in lipophilic drug intoxications and it can be used in unconscious patients who have cardiac and/or neurologic symptoms but no history of a specific drug ingestion.

    Tricyclic antidepressant intoxication is one of the most frequently encountered and life-threatening causes of intoxication among referrals to emergency departments due to drug intoxication. There is no known antidote against any of the tricyclic antidepressants. The American Society for Apheresis (ASFA) recommends plasmapheresis to support primary treatment in this type of drug poisoning, which does not respond to certain and traditional treatments. We present a 15-year-old girl who ingested amitriptyline with suicidal intent. On admission, she was in a comatose state (Glasgow Coma Scale score: 5), with no spontaneous respiration and presence of pathological reflexes. Due to the intake history of lethal doses and the severe clinical picture, plasmapheresis was performed. She was discharged on her fifth day of hospitalization.Due to the high plasma protein binding property of amitriptyline, plasma exchange therapy should be considered in cases of severe amitriptyline intoxication as a life-saving therapeutic modality.

    A case of unilateral sensorineural hearing loss of the left ear after carbon monoxide intoxication was presented. The diagnosis was based upon an interview, medical examinations and audiometric investigations. Results of diagnostic evaluations, clinical presentation and treatment were discussed. Hearing improvement was obtained after 6 days of treatment and normal hearing returned after 14 days. Patients who suffer from CO intoxication are at risk of hearing impairment, therefore, there is a need for audiometric follow up in these patients.

    The in vitro effect of chlorpromazine on hepatic alcohol dehydrogenase (L-ADH) was studied as a function of sex and species. The presence of chlorpromazine, 50 muMol, in reaction mixture noncompetitively inhibited rat L-ADH in a dose dependent fashion in the concentration range between 5 X 10(-5) Mol and 10(-4) Mol. This drug concentration also inhibited L-ADH of albino mice of both sexes, but chlorpromazine-produced a decrease in Km which was greater in the female than in the male mouse. Likewise, chlorpromazine, 50 muMol, noncompetitively inhibited mouse L-ADH of C57BL/6J, a mouse strain with ethanol preference, but without a concomitant change in the apparent Km. The KI50 determination indicates 3.5 fold lower concentration requirement of the drug in the C57BL mouse strain compared to that of the albino rat liver preparation. The results suggest that the inhibitory action of the drug on L-ADH and the genetic factor involved may influence the legal limit of serum ethanol concentration during alcohol intoxication in subjects under psychotropic medications. A medical forensic implication is suggested.

    An examination has been carried out on the relative efficacy of a number of chelating agents when acting as antagonists for oral cadmium chloride intoxication in mice. The compounds were administered orally after the oral administration of cadmium chloride at 1 mmol/kg. Of the compounds examined, several were useful in terms of enhancing survival, but by far the most effective in both enhancing survival and leaving minimal residual levels of cadmium in the liver and the kidney, was meso-2,3-dimercaptosuccinic acid (DMSA). Several polyaminocarboxylic acids also enhanced survival. The most effective of these in reducing liver and kidney levels of cadmium were diethylenetriaminepentaacetic acid (DTPA), trans-1,2-diaminocyclohexane-N,N,N'N'-tetraacetic acid (CDTA), and triethylenetetraminehexaacetic acid (TTHA). D-Penicillamine (DPA) was found to promote survival but also led to kidney cadmium levels higher than those found in the controls. Sodium 2,3-dimercaptopropane-1-sulfonate (DMPS) was as effective in promoting survival as DMSA but left levels of cadmium in the kidney and liver that were approximately four times greater than those found with DMSA.

    Intoxication in and around licensed premises continues to be common, despite widespread training in the responsible service of alcohol and laws prohibiting service to intoxicated individuals. However, research suggests that training and the existence of laws are unlikely to have an impact on intoxication without enforcement, and evidence from a number of countries indicates that laws prohibiting service to intoxicated individuals are rarely enforced. Enforcement is currently hampered by the lack of a standardized validated measure for defining intoxication clearly, a systematic approach to enforcement and the political will to address intoxication. We argue that adoption of key principles from successful interventions to prevent driving while intoxicated could be used to develop a model of consistent and sustainable enforcement. These principles include: applying validated and widely accepted criteria for defining when a person is 'intoxicated'; adopting a structure of enforceable consequences for violations; implementing procedures of unbiased enforcement; using publicity to ensure that there is a perceived high risk of being caught and punished; and developing the political will to support ongoing enforcement. Research can play a critical role in this process by: developing and validating criteria for defining intoxication based on observable behaviour; documenting the harms arising from intoxication, including risk curves associated with different levels of intoxication; estimating the policing, medical and social costs from intoxicated bar patrons; and conducting studies of the cost-effectiveness of different interventions to reduce intoxication.

    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

    On the basis of morphological examinations in light and electron microscope, the evaluation of methanol influence on the liver of rats was conducted. The examination was carried out in the group of 36 rats that were given a single dose of methanol (1.5 g/kg b.w.) into the stomach through a gastric tube. The liver was taken from rats under the ether anaesthesia after 6, 12, and 24 hours as well as after 2, 5, and 7 days of methanol administration. Results showed that methanol intoxication caused visible changes in the examined organ. Only 6 h after intoxication, lobular peripheral hepatocytes presented characteristic features of vacuolar degradation persisting up to 48 h. Since the second day of intoxication, many cells with double nuclei were found more frequently than in controls. Single hepatocytes or small hepatocytic clusters with the features of deliquescent necrosis could be seen after 5 and 7 days of examination. All animals intoxicated with methanol showed distinct weakness of glycogen reaction. The loss of glycogen resources was highest at 24 h after methanol administration. The results indicate, that methanol causes morphological changes in the rat liver and that intensification of these changes depends on the time after intoxication.

    We examined potential differences in women's likelihood of sexual risk taking in a laboratory setting based on alcohol intoxication and sexual abuse history. Participants (n = 64) were classified as non-sexually abused (NSA) or as having experienced sexual abuse in childhood only (CSA) or adulthood only (ASA) and randomly assigned to consume alcoholic (.06, .08, or .10% target blood alcohol content) or non-alcoholic drinks, after which participants read and responded to a risky sex vignette. Dependent measures included vaginal pulse amplitude, self-reported sexual arousal, likelihood of engaging in condom use and risky sexual behaviors described in the vignette, and mood. NSA and ASA women did not differ significantly on any dependent measures. CSA women reported significantly lower likelihood of condom use and unprotected intercourse relative to NSA and ASA women. Intoxicated women reported significantly greater sexual arousal, positive mood, and likelihood of risky sex relative to sober women. Intoxicated CSA women reported significantly more likelihood of unprotected oral sex and less likelihood of condom use relative to intoxicated NSA and ASA and sober CSA women. CSA women's increased risk of sexually transmitted infections (STIs) may be driven by non-condom use and behavioral changes while intoxicated. These findings provide preliminary insight into situational influences affecting CSA women's increased STI risk.

  15. Alcohol consumption and escalatory aggression in intoxicated and sober dyads.

    PubMed

    Leonard, K E

    1984-01-01

    It has been suggested that alcohol ingestion facilitates escalatory processes in aggressive interactions. The present study examined interaction patterns in intoxicated, sober and mixed dyads. Thirty pairs of men college students were randomly assigned to these conditions. Subjects who received alcohol received .964 g of absolute alcohol per kg of body weight. At the beginning of each trial in a reaction-time competition, each member of the dyad selected the shock level that he wanted his opponent to receive if the opponent was slower on the trial. Further, each member was informed by feedback lights of the shock level that his opponent had selected for him. The results indicated that the intoxicated dyads selected higher shock levels than did the sober dyads. Mixed dyads tended to select lower shock levels than intoxicated dyads but higher shock levels than sober dyads. However, these differences were not statistically significant. Additionally, intoxicated dyads escalated in aggression over the first block of six trials, whereas neither sober nor mixed dyads evidenced such an escalation. One interpretation of these findings is that the cognitive disruption caused by the alcohol interfered with the subjects' ability to evaluate the consequences of their behavior and to interpret the behavior of their opponents. A second interpretation is that, because of the expectancy effects associated with alcohol consumption, intoxicated dyads did not feel constrained to a nonaggressive stance. Finally, the value of the dyadic-interaction paradigm in the study of alcohol-related violence was discussed.

    Autopsy findings of fatal intoxication with yew (Taxus baccata) are nonspecific. A presence of plant residues in the digestive tract can signalize yew intoxication. If yew decoction is consumed, plant residues are not found. In such a case the intoxication can be signalized by the presence of 3,5-dimethoxyphenol in biological material. Authors of this article describe the proof and quantification of the 3,5-dimethoxyphenol in two cases of fatal intoxication with yew. In both cases the liquid/liquid extraction and solid phase extraction was used. Extracts obtained from the acidic and basic environment were analysed. Extracts from the acidic environment were methylated and the extracts from the basic environment were acetylated. The analyses were carried out by gas chromatography/mass spectrometry. In the blood of both intoxicated persons the presence of 3,5-dimethoxyphenol was proved and its concentration 82 ng/ml and 417 ng/ml was quantificated. In both cases the presence of 3,5-dimethoxyphenol was also proved in the gastric contents and urine.

    Intoxication with organophosphate (OP) and carbamate (CM) compounds is a common reason for presentation to the Emergency Department (ED) in La Paz, Bolivia. The objective of this study was to describe the demographics, presenting symptoms, and hospital course of patients presenting with OP or CM intoxication to the ED of the Hospital de Clinicas, La Paz, Bolivia, with the aim of determining which factors might predict a complicated hospital course. This was a retrospective chart review, using predefined criteria, of 300 patients who presented from January 1, 2003 to December 31, 2003. The intoxications were all oral, mostly intentional (97%), and in young patients (mean age 23.9 years, range 13-62 years). Females outnumbered males almost 2:1. The most common symptoms on presentation were abdominal pain (83%), nausea/vomiting (79%), miosis (72%), bronchorrhea (44%), diarrhea (41%), and fasciculations (31%). The most frequent complications were aspiration (18%), cardiopulmonary arrest (9%), and seizure (7%); mortality was 6%. Treatments included gastric lavage in 96% of patients, and atropine (median 5 mg per patient, range 0-48 mg). Miosis, bronchorrhea, diarrhea, and fasciculations at presentation were associated with a higher rate of complications. Although almost all intoxications were suicide attempts, less than half of patients received a psychiatric consultation. OP intoxication is a common cause of self-inflicted morbidity and mortality among young people in La Paz, Bolivia. Presence of miosis, bronchorrhea, diarrhea, and fasciculations at presentation suggest a higher likelihood of complications.

    Alcohol is the psychoactive substance most frequently associated with suicidal behavior. We hypothesized that the level of alcohol intoxication and the choice of specific methods of committing suicide are related. Suicides in the Southwestern Croatia in a 10-year period, especially regarding the method of committing and alcohol intoxication, were analyzed. Ten various methods of committing suicide were recorded. The average blood alcohol concentration at the moment of suicide was 0.68 g/kg with male, and 0.29 g/kg with female victims. The highest blood alcohol levels at the moment of suicide were recorded with suicides by explosive device (with the average blood alcohol concentration of 1.71 g/kg). This especially drastic method of suicide was rare in Croatia in a period prior to the Croatian Independence War (1991-1995), but its incidence significantly increased during the war and in a post-war period. These victims were not chronic alcoholics, but the excessive alcohol consumption occurred as a result of psychiatric disorders as a consequence of war stress they suffered.

    Lithium carbonate is commonly prescribed for the treatment of bipolar (manic-depressive) disorders. However, because of its narrow therapeutic index an excessive elevation of serum lithium concentration, either during chronic maintenance therapy or after an acute overdose, can result in serious toxicity. In addition to supportive care, the established treatment of severe lithium toxicity is haemodialysis. Conventional haemodialysis can reduce serum lithium rapidly, but post-dialysis rebound elevations with recurrent toxicity have been documented in old publications. High-flux membranes should be capable of removing more lithium per hour of haemodialysis, but published values are not available. We report here three patients with acute lithium intoxication who were treated successfully with bicarbonate and high-flux haemodialysis membranes. Our patients presented with a severe degree of intoxication, based on the amount of drug ingested, the initial serum lithium level, the severity of neurologic symptoms and systemic manifestations. Two patients developed acute renal failure probably as a result of volume depletion since it was rapidly reversible by haemodialysis and infusion therapy. In addition, consecutive haemodialysis sessions and improvement of renal function allowed a rapid decrease in serum lithium levels without haemodynamic instability or rebound elevations in lithium concentration. The effectiveness of the procedure in these cases can be attributed to the use of bicarbonate dialysate and high-efficiency dialysers. This is the first report describing the effect of high-efficiency dialysers on lithium pharmacokinetic. Using this technique the elimination rate of lithium was found to be greater than previously reported with haemodialysis.

    This research is based on epidemiological records of toxicological occurrences in individual records of investigation into pesticide poisoning at the Maringá Intoxication Control Center at the Regional University Hospital of Maringá. The intoxications in patients poisoned from 2002 to 2011, in towns that comprise the Central Northern Paraná Geographic Mesoregion where Maringá is located, were taken into consideration in this study. As a result, it was established that approximately 67.12% of those poisoned were males, the age groups most affected are 20-29 years old and 30-39 years old. Suicide attempts appear as the main motivation for hospitalization (possibly disguising the chronic intoxication), and mainly insecticides and herbicides are involved in the poisonings, with 62.60% and 26%, respectively. Lastly, the urgent need for public health policies in to reduce this statistic immediately is self-evident, as these poisonings are the ones recorded, as those resulting from food poisoning are not being computed.

    Chlorfenapyr is a moderately hazardous insecticide. There have been previous reports of chlorfenapyr intoxication, but none have reported patient survival or an association with pancreatitis. A 61-year-old woman was brought to the emergency department with vomiting after ingesting 10 mL chlorfenapyr in a suicide attempt 1 hour before. The patient was treated with gastric lavage and activated charcoal, then transferred to the intensive care unit. Initial laboratory data were unremarkable except for elevated amylase/lipase levels (134/222 U/L), which were even higher 7 days later and remained elevated for 2 weeks. Abdominal computed tomography showed diffuse pancreatic swelling. The patient improved with conservative care and was discharged to home 19 days after admission. This is the first reported case of survival after chlorfenapyr intoxication. We recommend early aggressive management in the emergency department and close monitoring in the intensive care unit to detect and treat potentially fatal deterioration after chlorfenapyr intoxication.

Laboratory findings included low levels of serum potassium, leucocytosis and elevated transaminases. The excretion rate of tin in the urine correlated with the severity of the intoxication. There was no measurable effect of plasma separation or d-penicillamine therapy on tin excretion in the urine or on the clinical picture. The long-term prognosis of severely intoxicated persons is poor. To prevent such events workers need to be warned of the risk and dangers of working with organo-metallic compounds. The effectiveness of protective clothes and gas masks should be checked. In exposed workers regular testing is advised of tin concentrations in the urine.

  4. Fatal water intoxication during olanzapine treatment: a case report.

    A man in his twenties was diagnosed with schizophrenia in his late teens. The night before his death, his family reported he drank a large amount of water, vomited, collapsed, and snored loudly while sleeping, but they did not view the event seriously as he did it routinely. The following morning, he was found dead. Autopsy revealed hyponatremia by water intoxication as the cause of death. Water intoxication has various causes. In this case, 610 ng/mL olanzapine was detected in serum samples. Although this concentration is not as high as the fatal concentrations reported in past studies, it might have caused some adverse effects. Furthermore, the observation that excessive drinking behavior started after the dose of olanzapine was increased suggests a possibility that olanzapine aggravated water intoxication.

    Carbamazepine is used in the treatment of epilepsy, and also prescribed in neuralgic pain syndromes, and certain affective disorders. Carbamazepine intoxication with suicide attempt is a relatively common clinical problem that can result in coma, respiratory depression, arrhythmia, hemodynamic instability and death. The drug's relatively high molecular weight, elevated volume of distribution and intense protein-binding render it difficult to extracorporeal removal, but published experience with hemoperfusion or hemodialysis present variable results. We describe a case report involving carbamazepine intoxication who was successfully treated with charcoal hemoperfusion. With this treatment the half-life of carbamazepine was reduced with rapid lowering of carbamazepine levels and clinical improvement. Based on our experience in this patient and a review of previously reported cases, extended charcoal hemoperfusion should be considered for serious carbamazepine intoxication because free as well as bound drug fractions are eliminated via this technique.

    Valproic acid is increasingly used in the treatment of epilepsy, and also prescribed for bipolar affective disorders, schizoaffective disorders, schizophrenia and migraine prophylaxis. Valproic acid intoxication with suicide attempt is a relatively common clinical problem that can result in coma, respiratory depression, pancytopenia, hemodynamic instability and death. The drug's relatively low molecular weight, small volume of distribution and saturable protein-binding render it potentially amenable to exracorporeal removal (hemodialysis, hemoperfusion or hemofiltration ), but published experience is scarce. We describe a case report involving valproic acid intoxication with ingestion of ethanol, who was successfully treated with charcoal hemoperfusion. With this treatment the half-life of valproic acid was reduced with rapid lowering of valproic acid levels and clinical improvement. Based on our experience in this patient and a review of previously reported cases, charcoal hemoperfusion should be considered for serious valproic acid intoxication because free as well as bound drug fractions are eliminated via this technique.

    Renal fluoride toxicity in human beings is difficult to assess in the literature. Although experimental studies and research on methoxyflurane toxicity have shown frank renal damage, observations of renal insufficiency related to chronic fluoride exposure are scarce. We report a case of fluoride intoxication related to potomania of Vichy water, a highly mineralized water containing 8.5 mg/L of fluoride. Features of fluoride osteosclerosis were prominent and end-stage renal failure was present. The young age of the patient, the long duration of high fluoride intake, and the absence of other cause of renal insufficiency suggest a causal relationship between fluoride intoxication and renal failure.

    Acute water intoxication with deepening coma and uncontrolled epileptiform seizures in a 25-year-old previously fit male schizophrenic was treated with hypertonic (2 N) saline and a 20% mannitol solution. This improved his neurological state but precipitated severe pulmonary oedema. Intravenous frusemide increased his urinary output sufficiently to clear the pulmonary oedema. In acute water intoxication the use of hypertonic solutions may thus precipitate left heart failure by expanding the intra-pulmonary blood volume beyond the capacity of even a healthy left ventricle to compensate. Simple water restriction will produce a slower but perhaps safer improvement. Images Fig. 1 PMID:981097

    Eleven episodes of severe hyponatremia secondary to hiccup-induced potomania were recorded in 3 years in a man who had essential hypertension, a low protein intake and a normal diluting ability. Paradoxical increase in hematocrit and plasma protein with acute extensive natriuresis was associated as well as urine potassium loss and hypokalemia producing paralysis in 1 episode. During a chronic water loading test, the defect in water excretion was related to a low urine solute delivery which was partially reverted by the natriuretic response to plasma volume expansion, promoting water diuresis. In acute water intoxication, this natriuretic response was exaggerated, producing a brisk water diuresis. Plasma volume was rapidly normalized but without any improvement in plasma sodium due to the concomitant negative sodium balance. Thus, water diuresis persisted until plasma volume was significantly contracted. Potassium loss appeared to be related to sodium excretion. Metabolic disturbances have not reoccurred despite persistent hiccup and potomania during 2 years of urea therapy.

    Over the past decade, star fruit (Averrhoa carambola) intoxication decreased in the Taiwanese society due to improved public education on chronic kidney disease (CKD). Various complications including hiccups, altered levels of consciousness, coma, and seizures have been reported in individuals with renal failure who ingested fresh star fruit or star fruit juice. A high mortality rate (from 33 to 80%) was observed in patients with altered levels of consciousness, despite prompt dialysis and supportive care. According to previous case reports, the proposed treatment of choice for severe star fruit intoxication may be continuous renal replacement therapy with or without hemoperfusion. We report two cases of star fruit intoxication with stage V CKD (one case is predialysis) presenting with coma and generalized tonic-clonic seizures. The two patients were treated with sustained low-efficiency daily diafiltration (SLEDD-f) and charcoal hemoperfusion. Status epilepticus was controlled fairly quickly after treatment with SLEDD-f and hemoperfusion. However, the outcomes in this report are still poor (both remained comatose; one of two patients died). Currently, there are no data for the use of SLEDD-f with hemoperfusion for severe star fruit intoxication. SLEDD-f with charcoal hemoperfusion may play a role in managing refractory status epilepticus in patients with severe star fruit poisoning.

  19. A Systematic Review of Intervening to Prevent Driving While Intoxicated

    2016-01-01

    Background Driving while intoxicated (DWI) is a significant public health issue. The likelihood someone will intervene to prevent driving while intoxicated is affected by the characteristics of the individuals and the context of the potential driving scenario. Understanding such contexts may help tailor public health messages to promote intervening from those who are nearby to an intoxicated driver. Objective This systematic review investigates the behavior of those close to an intoxicated driver and factors associated with increasing the likelihood they will intervene in situations where driving while impaired may be likely. The review of the literature is guided by an orienting framework, namely the classic social psychology theory of decision-making proposed by Latané and Darley. Results Drawing upon this framework, the review examines the extent to which research has focused on factors which influence whether or not an individual identifies a need to intervene and identifies a serious/dangerous situation. In addition, consideration is given to perceived personal responsibility. The final two components of the model are then discussed; the perceived skill an individual who may intervene has (in their ability to intervene) and their actual enactment of the intervening behavior. Conclusions/Importance Drawing upon such a well-considered theoretical framework, this review provides guidance on key components likely to assist in the development of targeted, more effective public education messages/campaigns that dissuade individuals from drinking and then driving.

    This observational study aimed at evaluating recent superwarfarin intoxication of Korean patients. Ten patients were diagnosed as or highly suspicious for superwarfarin intoxication. Case report forms described by attending hematologists of the patients were collected and analyzed. Bleeding symptoms were varied among the patients. Patients uniformly showed prolonged prothrombin time (PT) and activated thromboplastin time (aPTT) with decreased activity of vitamin K dependent coagulation factors. Positive serum brodifacoum test results in 4 of 5 requested patients contributed to confirmatory diagnosis. Psychiatric interview revealed an attempted ingestion in one patient. High dose vitamin K1 therapy promptly corrected prolonged PT and aPTT, but hasty discontinuation caused repeated bleeding diathesis in 6 patients. Route of intoxication was unknown or not definite among 8 of 10 patients. Three patients had a possibility of environmental exposure considering their occupations: there might be intoxication by transdermal absorption or inhalation. Therefore, high dose and prolonged use of vitamin K1 therapy is necessary for effective detoxification. Further detailed investigation on environmental exposure and efforts to improve availability of the blood level test in clinic are requested. PMID:21165290

    2009-09-01

    Since superwarfarin is popular and readily available in stores, it may cause intoxication or overexposure, which can result in coagulopathy or abnormal bleeding in humans and, thus, is an important public health problem. We report our clinical experience with superwarfarin intoxication. Nine patients, including eight patients who had histories of ingesting superwarfarin, were studied. Of the patients, hematuria occurred in eight. Laboratory tests among the nine patients showed extremely prolonged prothrombin times and activated partial thromboplastin times, which could be corrected to normal by mixing 1:1 with normal pooled plasma; they also had very low functional levels of factor II, VII, IX, X, and proteins C and S, but normal functional levels of factors V, VIII, fibrinogen, and anti-thrombin III. Large doses of vitamin K1 were needed for 3 months or more to treat and correct the coagulopathy among the patients. The majority of the patients presented with gross hematuria, suggesting that hematuria is probably a major clinical manifestation of superwarfarin intoxication. Prolonged use of large doses of vitamin K1 is needed for the treatment of superwarfarin intoxication.

    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

    There is a distinct correlation between aluminium (Al) intoxication and neurodegenerative diseases (ND). We demonstrated how patients affected by ND showing Al intoxication benefit from short-term treatment with calcium disodium ethylene diamine tetraacetic acid (EDTA) (chelation therapy). Such therapy further improved through daily treatment with the antioxidant Cellfood. In the present study we examined the efficacy of long-term treatment, using both EDTA and Cellfood. Slow intravenous treatment with the chelating agent EDTA (2 g/10 mL diluted in 500 mL physiological saline administered in 2 h) (chelation test) removed Al, which was detected (using inductively coupled plasma mass spectrometry) in urine samples collected from patients over 12 h. Patients that revealed Al intoxication (expressed in μg per g creatinine) underwent EDTA chelation therapy once a week for ten weeks, then once every two weeks for a further six or twelve months. At the end of treatment (a total of 22 or 34 chelation therapies, respectively), associated with daily assumption of Cellfood, Al levels in the urine samples were analysed. In addition, the following blood parameters were determined: homocysteine, vitamin B12, and folate, as well as the oxidative status e.g. reactive oxygen species (ROS), total antioxidant capacity (TAC), oxidized LDL (oxLDL), and glutathione. Our results showed that Al intoxication reduced significantly following EDTA and Cellfood treatment, and clinical symptoms improved. After treatment, ROS, oxLDL, and homocysteine decreased significantly, whereas vitamin B12, folate and TAC improved significantly. In conclusion, our data show the efficacy of chelation therapy associated with Cellfood in subjects affected by Al intoxication who have developed ND.

    Intoxication and overdose are common presenting complaints to the emergency department. Acute intoxication with lysergic acid diethylamide (LSD) has become a relatively rare event, especially when compared with the incidence of ethanol and cocaine intoxication. We recently had an outbreak of presumed LSD intoxications occurring over one weekend. All patients had attended a performance by the musical group The Grateful Dead. At present, LSD intoxication or overdose can only be suspected based on clinical findings because there are no readily available rapid laboratory tests for detecting either the parent compound or the metabolites of the drug. The clinical findings and outcomes of five patients with suspected LSD intoxication are presented. The pharmacological effects of LSD and treatment modalities of intoxication are reviewed. All patients were treated conservatively based on clinical signs and symptoms. Only one patient required hospital admission for combative behavior that was initially refractory to pharmacological restraint.

  20. Brain acetylcholinesterase activity recovery following acute methyl parathion intoxication in two feral rodent species: comparison to laboratory rodents

    1988-07-01

    Widespread use of organophosphorus insecticides (OPs) has produced both acute and chronic intoxication among nontarget organisms. Most such studies have included fish and birds as opposed to mammals. However, numerous OP toxicity studies have been conducted on laboratory rodents creating a temptation to apply this data to feral rodents. Chronic OP exposure has been reported to produce cholinergic adaptation which in turn lowers mortality rates following a subsequent acute anticholinesterase exposure. The relevance that these laboratory rodent studies have on feral rodents is subject to debate. Field studies involving OP exposure among nontarget feral mammals have produced contradictory results. Increased mortality as a result of repeated OP application has been reported. This observation may be of considerable importance to nontarget feral rodent populations due to the repetitive nature of OP application protocols. The ability of feral rodents to recover brain AChE activity (BAA) between OP application intervals undoubtedly promotes their survival. This study investigated and compared BAA recovery following acute oral methyl parathion intoxication among 2 feral rodent species and among 2 common laboratory rodent species.

    Plasma sodium and osmolality were determined in 80 adult epileptic patients receiving chronic treatment with carbamazepine and in 50 control patients treated with other anticonvulsant drugs. Mean plasma osmolality was significantly lower in the carbamazepine-treated patients but mean plasma sodium did not differ in the two groups. Hyponatraemia was found in five of the carbamazine-treated patients and hypo-osmolality in six. None of the control patients had hyponatraemia and only one had a borderline low osmolality. Three of the 13 patients receiving carbamazepine alone were hyponatraemic. Plasma sodium concentration correlated negatively with both daily carbamazepine dose and serum carbamazepine level. Free water clearance after an oral water load was determined in six patients on carbamazepine alone and in six normal subjects not receiving drug therapy. The capacity of some of the patients to excrete the water load was found to be grossly impaired. PMID:681958

  2. Gender Differences in Natural Language Factors of Subjective Intoxication in College Students: An Experimental Vignette Study

    Background 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., 2009) 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. Method 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). Results 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. Conclusions 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.

    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.

  4. The role of therapeutic plasma exchange in poisonings and intoxications.

    Poisonings, intoxications, and drug overdoses are common occurrences and rapid lowering of the toxin level is a cornerstone of all effective therapies. Therapeutic plasma exchange (TPE) has several unique characteristics that allow it to be a potentially effective therapy in rapidly achieving this goal. Specifically, TPE allows for the removal of large molecular weight, protein-bound molecules that have a small volume of distribution. Due to the nature of poisonings, intoxications, and drug overdoses, no randomized controlled trials studying the efficacy of TPE in these situations exist. Thus, careful interpretation and analysis of case reports and series are required to assess the potential efficacy of this therapy. Recent data suggest that TPE may also be effective in the therapy of patients receiving biologic treatments who develop life-threatening complications due to therapy.

  5. Alcohol-based hand sanitizers: severe intoxication in children.

    PubMed

    2012-07-01

    Alcohol-based hand sanitizers are an alternative to hand washing with soap and water when water is unavailable. Their use has increased over the last decade. Cases of acute intoxication have been reported in children after accidental ingestion of alcohol-based hand sanitizers, sometimes leading to inebriation, agitation, drowsiness, impaired consciousness, and blood alcohol levels sometimes exceeding 2 g/I. In practice, alcohol-based hand sanitizers should be kept out of reach of children and should only be used when hand washing with soap and water is not possible. The possibility of alcohol intoxication should be borne in mind when a child suddenly presents with behaviour problems or altered consciousness.

    Random mandatory urine drug screening is a routine practice in the military. The pressure to produce a urine specimen creates a temptation to consume large volumes of water, putting those individuals at risk of acute water intoxication. This occurs when the amount of water consumed exceeds the kidney's ability to excrete it, resulting in hyponatremia owing to excess amount of water compared to serum solutes. The acute drop in serum osmolality leads to cerebral edema, causing headaches, confusion, seizures, and death. There has been increasing awareness of the danger of overhydration among performance athletes, but dangers in other groups can be underappreciated. We present the case of a 37-year-old male Air Force officer who developed acute water intoxication during urine drug screening. Our case demonstrates the need for a clear Air Force policy for mandatory drug testing to minimize the risk of developing this potentially fatal condition.

    Forensic medical examiners know numerous cases of non-occupational intoxication (e.g. suicide, drug intoxication, household poisoning) but rarely encounter cases of occupational poisoning with household gases. Collection of forensic chemical facts testifying to the presence of saturated hydrocarbons in blood and other tissues is a challenging task. It hampers evaluation of their toxic effect on human brain for the purpose of forensic medical examination. A method is proposed for the analysis of biological materials allowing for the detection of natural alkanes, such as butane, along with recommendations on taking samples for chemical analysis in suspected cases of poisoning with household gases. The method is designed to be employed in combination with up-to-date analytical techniques, such as capillary gas chromatography and mass spectrometry.

    1981-03-01

    An episode is described in which tissue culture in a laboratory could have become intoxicated due to the recirculation of toxic exhaust fumes extruded from the roof of a research institution. A route of entry was found whereby a portion of fume hood exhaust was reintroduced into the building by means of large intake fans located on the roof near the exhaust ducts used to cool the elevator cables and motors at the top of the elevator shafts. The descending action of the elevator created a suction which pulled the polluted air down the elevated shafts and into the corridors. Such mechanisms for cooling elevator shafts are widely used in the modern architecture of commercial, industrial and laboratory buildings, and they should therefore be considered in epidemiologic investigations of airborne infections or intoxications of undetermined origin.

    The clinical presentation of lead intoxication may vary widely and in the absence of a high clinical index of suspicion, the diagnosis may be missed. The effects of lead on mitochondrial oxidative phosphorylation and its interaction with calcium-mediated processes explain the heterogenous presentation. In this case report, the diagnosis was finally made when bilateral wrist drop developed on top of abdominal cramps and anemia. Before, ascites raised the suspicion of a tumor. Therefore, each element of the triad of unexplained anemia, abdominal cramps, and bilateral wrist (or foot) drop should lead any physician to consider the diagnosis of lead intoxication. This case also illustrates the importance of a careful and meticulous social history in patient management. PMID:16808730

    In recent years, there has been a growing interest in using baclofen for the management of alcohol use disorder. This off-label indication usually involves high doses of the medication. We report a case of severe baclofen overdose in a 66-year-old man. The patient was found severely agitated, and he presented with delirium and auditory hallucinations. At hospital admission, his daily dose was 180 mg baclofen. He was admitted to the intensive care unit for sedation and supportive care. When sedation was withdrawn, the patient presented with a normal neurological status. In this clinical context, baclofen intoxication was suspected. This was confirmed by measuring blood baclofen levels. This intoxication was probably mediated by a combination of risk factors including a high daily dose of baclofen and acute renal failure, conducive to drug accumulation.

    We reported the case of a 70-year-old woman with moderate renal failure due to anti-neutrophil cytoplasmic antibody-related glomerulonephritis who developed symptomatic water intoxication (serum Na: 108 mEq/L) following treatment with oral low-dose cyclophosphamide (CY) (50mg/day). Estimated glomerular filtration rate was 29.5 mL/min/1.73 m2. She had drunk >2 L of fluid in 12 h prior to the development of cerebral oedema. This rare case suggests that oral low-dose CY could be an occult cause of water intoxication in patients with chronic kidney disease taking large fluid volumes. PMID:18795141

The case we describe here had similar features but in addition showed striking laminar necrosis of the cerebral cortex. This finding in cyanide poisoning has been previously demonstrated by neuroimaging, but not pathologically.

    Doxylamine succinate is an antihistaminic drugwith additional hypnotic, anticholinergic and local anesthetic effects first described in 1948. In Korea and many other countries, it is a common-over-the counter medication frequently involved in overdoses. Clinical symtomatology of doxylamine succinate overdose includes somnolence, coma, seizures, mydriasis, tachycardia, psychosis, and rhabdomyolysis. A serious complication may be rhabdomyolysis with subsequent impairment of renal function and acute renal failure. We report a case of acute renal failure and acute pancreatitis complicating a doxylamine succinate intoxication.

    ABSTRACT Currently, whether hormonal contraceptives affect male to female human immunodeficiency virus (HIV) transmission is being debated. In this study, we investigated whether the use of progesterone-based intrauterine devices (pIUDs) is associated with a thinning effect on the ectocervical squamous epithelium, down-regulation of epithelial junction proteins, and/or alteration of HIV target cell distribution in the human ectocervix. Ectocervical tissue biopsies from healthy premenopausal volunteers using pIUDs were collected and compared to biopsies obtained from two control groups, namely women using combined oral contraceptives (COCs) or who do not use hormonal contraceptives. In situ staining and image analysis were used to measure epithelial thickness and the presence of HIV receptors in tissue biopsies. Messenger RNA levels of epithelial junction markers were measured by quantitative PCR. The epithelial thickness displayed by women in the pIUD group was similar to those in the COC group, but significantly thinner as compared to women in the no hormonal contraceptive group. The thinner epithelial layer of the pIUD group was specific to the apical layer of the ectocervix. Furthermore, the pIUD group expressed significantly lower levels of the tight junction marker ZO-1 within the epithelium as compared to the COC group. Similar expression levels of HIV receptors and coreceptors CD4, CCR5, DC-SIGN, and Langerin were observed in the three study groups. Thus, women using pIUD displayed a thinner apical layer of the ectocervical epithelium and reduced ZO-1 expression as compared to control groups. These data suggest that pIUD use may weaken the ectocervical epithelial barrier against invading pathogens, including HIV. PMID:25588510

    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.

    Cyanide intoxication, which has been used as a model of energy depletion at cardiac sympathetic nerve terminals, causes non-exocytotic release of norepinephrine (NE). However, the effect of cyanide intoxication on cardiac epinephrine (Epi) release remains unknown. Using cardiac microdialysis in the rabbit, we measured dialysate Epi and NE concentrations as indices of myocardial interstitial Epi and NE levels, respectively. Local administration of sodium cyanide (30 mM) through the dialysis probe increased both Epi and NE levels (from 11.3+/-2.3 to 32.3+/-4.4 pg/ml and from 33.6+/-6.1 to 389.0+/-71.8 pg/ml, respectively, mean+/-S.E., P<0.01). Local desipramine (100 microM) administration suppressed the cyanide induced NE response without affecting the Epi response. In contrast, local omega-conotoxin GVIA (10 microM) administration partially suppressed the cyanide induced NE response and totally abolished the Epi response. In conclusion, cyanide intoxication causes N-type Ca(2+) channel dependent exocytotic Epi release as well as inducing N-type Ca(2+) channel independent non-exocytotic NE release.

    By using an anonymous postcard reporting system, data of n=358 children, adolescents, and young adults who were treated in 26 emergency departments because of acute alcohol intoxication were collected. The aim of this study was to estimate the prevalence of acute alcohol intoxications in Hamburg, compare these data with the official hospital diagnosis register, and analyze the circumstances that led to the intoxication. A total of 358 cases were reported by the postcard system. Age ranged from 11-21 years, with 64.5% being 14-17 years old. Data were collected in the municipal area of Hamburg during the calendar year of 2008. The percentage of female patients was 65.6% in the age group from 11-17 years and decreased in the age group of patients being 18 years and older. A vast majority of patients were admitted by ambulance and were reported as being a"first offender". On average, male patients showed a higher level of blood alcohol when being admitted (2.02 ‰) than female patients (1.76 ‰). The older the age group, the higher the blood alcohol level. Among drinking circumstances, the situation"drank together with friends" was most frequently reported. In comparison with the official hospital diagnosis register, prevalence was 31.6% higher. This could mean that the prevalence reported in the official hospital diagnosis register is an underestimation of the actual case numbers.

    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.

  2. Preserved Ross-age(?) root beneath the Transantarctic Mountains and origin of the thinner crust beneath the northern Wilkes Subglacial Basin

    The Wilkes Subglacial Basin, in the hinterland of the Transantarctic Mountains, represents one of the least understood continental-scale features in Antarctica. Aeromagnetic data suggests that this basin was imposed on a much earlier Ross age back arc region that developed along the former active margin of the East Antarctic Craton (Ferraccioli et al., 2009, Tectonophysics). However, the deeper crustal structure of the basin and its relation with tectonic evolution remains both disputed and poorly constrained. Here, we present new airborne gravity data that reveal the crustal architecture of the northern Wilkes Subglacial Basin. Our gravity models indicate that the crust under the northern Wilkes Subglacial Basin is likely to be 30-35 km thick, i.e. 5-10 km thinner than imaged under the adjacent Transantarctic Mountains, and ~15 km thinner than predicted from some previous flexural and passive seismic models beneath the southern Wilkes Subglacial Basin region. We infer that crustal thickening under northern Victoria Land reflects Ross-age (ca 500 Ma) orogenic events and accretion, followed by partial preservation of the orogenic root since then, as opposed to reflecting the edge of a Mesozoic plateau, which has previously been inferred to have occupied West Antarctica (Bialas et al. 2007, Geology). Airy isostatic anomalies along both flanks of the Wilkes Basin reveal major inherited tectonic structures, which likely controlled the basin location and hence support aeromagnetic interpretations of the Wilkes Subglacial Basin as a structurally controlled basin. The positive anomaly along the western margin of the basin appears to define the tectonic boundary between the East Antarctic Craton and the Ross Orogen, and the anomaly along its eastern flank is interpreted as reflecting high-grade and denser rocks of the central Wilson Terran,e with respect to lower grade meta-sediments and magmatic arc rocks of the western Wilson Terrane and Wilkes Basin region.

  3. Reversal by phenytoin of carbamazepine-induced water intoxication: a pharmacokinetic interaction.

    PubMed Central

    Perucca, E; Richens, A

    1980-01-01

    The hypothesis that phenytoin may antagonise the antidiuretic effect of carbamazepine has been examined by comparing the free water clearance response to a standard water load in 36 patients stabilised on different drug regimes. The diuretic response to the water load was significantly greater in patients receiving chronic treatment with carbamazepine and phenytoin in combination than in matched control subjects receiving carbamazepine as a single drug. Acute administration of phenytoin (1,100 mg), however, had no significant influence on carbamazepine-induced antidiuresis. Evidence is presented that reversal of the antidiuretic effect of carbamazepine by chronic phenytoin administration is secondary to a marked reduction of the serum carbamazepine concentration during combined therapy. These results suggest that the risk of developing water intoxication is greater in patients receiving carbamazepine alone than in those receiving phenytoin in combination. Since the antidiuretic effect is correlated with the serum carbamazepine concentration rather than with the prescribed daily dose, monitoring the serum level of the drug is likely to provide the best rational approach to the prevention of excessive water retention.

People exhibiting this kind of show are professionals, not rare amateurs, who use different kind of fuels, usually hydrocarbons, in order to produce a pillar of fire. Intoxications caused by ingestion or inhalation of liquid paraffin, used as a fuel while performing, are numerous and various. We present a clinical case report of a 25-year old, previously healthy, amateur "fire-breather". During October, 2010 this young men arrived at the Emergency Unit of the University Clinic for toxicology and Urgent Internal Medicine in a severe clinical condition, after his unsuccessful attempt to perform real "fire-breathing". He had fever, strong headaches, mild abdominal and chest pain and he also had difficulties breathing and persistent dry cough. The patient was extremely dyspneic with peripheral cyanosis and shortness of breath. "Fire-breathers" must be viewed as a population at risk of paraffin-induced pneumonia, which has low mortality rate, but still is related with numerous and various chronic complications. Our patient was first in a life threatening, extremely serious clinical condition which was urgently treated with appropriate vigorous and effective therapy. This therapeutic protocol led to successful full recovery of these young men, who luckily didn't exhibit any chronic complications.

    We examined party characteristics across different college drinking settings, associations between party characteristics and likelihood of drinking to intoxication, and the mediating role of perceived prevalence of intoxicated partygoers. Students (N = 6903) attending 14 public universities in California during the 2010 and 2011 fall semesters completed surveys on individual and party characteristics in six unique settings (e.g., residence hall). We used descriptive statistics to examine party characteristics by setting. We estimated multilevel logistic regression models to identify party characteristics associated with drinking to intoxication, and we used RMediation to determine significance of mediating effects. Individual and party characteristics varied by drinking context. Greater time at a party was associated with drinking to intoxication at five of six settings, while larger party size was significant only for outdoor settings. Enforcing the legal drinking age and refusing to serve intoxicated patrons were associated with lower likelihood of intoxication at Greek and off-campus parties. The presence of a keg was associated with drinking to intoxication at Greek, off-campus and outdoor parties; at bars, cover charges and drink promotions were positively associated with drinking to intoxication. In four of six settings, we found evidence of significant mediating effects through perceived prevalence of intoxicated partygoers. Findings highlight risk and protective characteristics of parties by drinking setting, and have prevention implications. PMID:25976418

The consumption of medications prescribed by a physician can form the basis of an involuntary-intoxication defense. In this article, I review cases where defendants relied on the use of prescribed medications for an involuntary-intoxication defense. The medications most frequently implicated by defendants are listed by name and by class. From the case law, I provide a summary of the defense and a review of the pitfalls of the defense to serve as practice pointers for forensic evaluators.

    Drugs are the main causal agents in intoxications with suicidal purpose. Salicylates are few frequently related. In this paper we reported a patient with suspicion of acute exogenous intoxication with salicylates. The patient showed clinical symptoms of fever, hypoglycemia, low cardiac rhythm, hyperventilation, pulmonary edema and coma. We employed analytical toxicology to elucidate the drug involved in the intoxication, using thin layer chromatography (TLC) and infrared spectrometry to detect acetyl salicylic acid, as the cause agent of intoxication clinical pattern, in acids extracts from urine and gastric content. The analytical results corresponds with clinical symptoms showed by the patient and the information obtained by medical monitoring of him.

    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.

    Metformin intoxication with lactic acidosis, a potentially lethal condition, may develop in diabetic patients when the drug dose is inappropriate and/or its clearance is reduced. Diagnosis and therapy may be delayed due to nonspecific symptoms at presentation, with severe anion gap metabolic acidosis and elevated serum creatinine values being the most prominent laboratory findings. Confirmation requires measurement of serum metformin by high-performance liquid chromatography-tandem mass spectrometry, but this technique is available only at specialized institutions and cannot be relied on as a guide to immediate treatment. Thus, based on strong clinical suspicion, renal replacement therapy must be started promptly to achieve efficient drug clearance and correct the metabolic acidosis. However, because metformin accumulates in the intracellular compartment with prolonged treatment, a rebound in serum concentrations due to redistribution is expected at the end of dialysis. We report a case of metformin intoxication, severe lactic acidosis, and acute kidney injury in a diabetic patient with pre-existing chronic kidney disease stage 3, treated effectively with sustained low-efficiency dialysis. We discuss the pathophysiology, differential diagnosis, and treatment options and highlight specific pharmacokinetic issues that should be considered in selecting the appropriate modality of renal replacement therapy.

  13. Circulatory Failure During Noninhaled Forms of Cyanide Intoxication.

    Our objective was to determine how circulatory failure develops following systemic administration of potassium cyanide (KCN). We used a noninhaled modality of intoxication, wherein the change in breathing pattern would not influence the diffusion of CN into the blood, akin to the effects of ingesting toxic levels of CN. In a group of 300 to 400 g rats, CN-induced coma (CN i.p., 7 mg/kg) produced a central apnea within 2 to 3 min along with a potent and prolonged gasping pattern leading to autoresuscitation in 38% of the animals. Motor deficits and neuronal necrosis were nevertheless observed in the surviving animals. To clarify the mechanisms leading to potential autoresuscitation versus asystole, 12 urethane-anesthetized rats were then exposed to the lowest possible levels of CN exposure that would lead to breathing depression within 7 to 8 min; this dose averaged 0.375 mg/kg/min i.v. At this level of intoxication, a cardiac depression developed several minutes only after the onset of the apnea, leading to cardiac asystole as PaO2 reached value approximately 15 Torr, unless breathing was maintained by mechanical ventilation or through spontaneous gasping. Higher levels of KCN exposure in 10 animals provoked a primary cardiac depression, which led to a rapid cardiac arrest by pulseless electrical activity (PEA) despite the maintenance of PaO2 by mechanical ventilation. These effects were totally unrelated to the potassium contained in KCN. It is concluded that circulatory failure can develop as a direct consequence of CN-induced apnea but in a narrow range of exposure. In this "low" range, maintaining pulmonary gas exchange after exposure, through mechanical ventilation (or spontaneous gasping), can reverse cardiac depression and restore spontaneous breathing. At higher level of intoxication, cardiac depression is to be treated as a specific and spontaneously irreversible consequence of CN exposure, leading to a PEA.

    Potassium cyanide (KCN) is an inhibitor of cytochrome C oxidase causing rapid death due to hypoxia. A well-characterized model of oral KCN intoxication is needed to test new therapeutics under the Food and Drug Administration Animal Rule. Clinical signs, plasma pH and lactate concentrations, biomarkers, histopathology, and cyanide and thiocyanate toxicokinetics were used to characterize the pathology of KCN intoxication in adult and juvenile mice. The acute oral LD50s were determined to be 11.8, 11.0, 10.9, and 9.9 mg/kg in water for adult male, adult female, juvenile male, and juvenile female mice, respectively. The time to death was rapid and dose dependent; juvenile mice had a shorter mean time to death. Juvenile mice displayed a more rapid onset and higher incidence of seizures. The time to observance of respiratory signs and prostration was rapid, but mice surviving beyond 2 hours generally recovered fully within 8 hours. At doses up to the LD50, there were no gross necropsy or microscopic findings clearly attributed to administration of KCN in juvenile or adult CD-1 mice from 24 hours to 28 days post-KCN challenge. Toxicokinetic analysis indicated rapid uptake, metabolism, and clearance of plasma cyanide. Potassium cyanide caused a rapid, dose-related decrease in blood pH and increase in serum lactate concentration. An increase in fatty acid-binding protein 3 was observed at 11.5 mg/kg KCN in adult but not in juvenile mice. These studies provide a characterization of KCN intoxication in adult and juvenile mice that can be used to screen or conduct preclinical efficacy studies of potential countermeasures.

    Background: Driving while under the influence of alcohol is a major public health problem whose neural basis is not well understood. In a recently published fMRI study (Meda et al, 2009), our group identified five, independent critical driving-associated brain circuits whose inter-regional connectivity was disrupted by alcohol intoxication. However, the functional connectivity between these circuits has not yet been explored in order to determine how these networks communicate with each other during sober and alcohol-intoxicated states. Methods: In the current study, we explored such differences in connections between the above brain circuits and driving behavior, under the influence of alcohol versus placebo. Forty social drinkers who drove regularly underwent fMRI scans during virtual reality driving simulations following two alcohol doses, placebo and an individualized dose producing blood alcohol concentrations (BACs) of 0.10%. Results: At the active dose, we found specific disruptions of functional network connectivity between the frontal-temporal-basal ganglia and the cerebellar circuits. The temporal connectivity between these two circuits was found to be less correlated (p <0.05) when driving under the influence of alcohol. This disconnection was also associated with an abnormal driving behavior (unstable motor vehicle steering). Conclusions: Connections between frontal-temporal-basal ganglia and cerebellum have recently been explored; these may be responsible in part for maintaining normal motor behavior by integrating their overlapping motor control functions. These connections appear to be disrupted by alcohol intoxication, in turn associated with an explicit type of impaired driving behavior. PMID:20028354

    Cardioprotective properties of GABA analogs under conditions of acute alcoholic intoxication have been studied using the following functional tests: volume loads, tests for adrenoreactivity, and maximum isometric load. The experiments showed that a 32% aqueous ethanol solution intraperitoneally injected in a dose of 8 g/kg produces a cardiotoxic action, which is manifested by a decrease in the inotropic reserve in load tests. Citrocard (50 mg/kg), phenibut (50 mg/kg), and piracetam (200 mg/kg) prevent the alcohol-induced myocardium injury, as shown by the heart contractility retained on a higher level in the test group than in the control group.

    Consultations at pediatric emergency units for acute consciousness alterations is frequent. Miscellaneous causes include cranial trauma, meningoencephalitis, metabolic disorders, drugs, or other intoxications. We report here eight cases of infants who were brought to the emergency division due to acute consciousness failure after accidental ingestion of hashish, confirmed by urinary dosage of Δ9-tetrahydrocannabinol. This series of under 24-month-old infants only emphasizes the value of screening for cannabis in urine in cases of abnormal consciousness and/or abnormal behavior in an infant.

    Cyclophosphamide is frequently used for the treatment of severe lupus nephritis, but is very rarely associated with dilutional hyponatremia. Recently we experienced a case of water intoxication following low-dose intravenous cyclophosphamide. Five hours after one dose of intravenous pulse cyclophosphamide 750 mg, the patient developed nausea, vomiting, and general weakness. Serum sodium concentration revealed 114 mEq/L and her hyponatremia was initially treated with hypertonic saline infusion. Then her serum sodium concentration rapidly recovered to normal with water restriction alone. During the course of intravenous pulse cyclophosphamide therapy, one must be aware of the possibility of significant water retention. PMID:24459501

    Pregnenolone is considered the inactive precursor of all steroid hormones, and its potential functional effects have been largely uninvestigated. The administration of the main active principle of Cannabis sativa (marijuana), Δ(9)-tetrahydrocannabinol (THC), substantially increases the synthesis of pregnenolone in the brain via activation of the type-1 cannabinoid (CB1) receptor. Pregnenolone then, acting as a signaling-specific inhibitor of the CB1 receptor, reduces several effects of THC. This negative feedback mediated by pregnenolone reveals a previously unknown paracrine/autocrine loop protecting the brain from CB1 receptor overactivation that could open an unforeseen approach for the treatment of cannabis intoxication and addiction.

    In order to examine whether pornography consumption is associated with risky sexual behaviour among emerging adults, we examined two large samples of those who reported hooking up in the past 12 months (combined n =  1216). Pornography use was associated with a higher likelihood of having a penetrative hookup; a higher incidence of intoxication during hookups for men (but a lower incidence of intoxication during hookups for women); increasing levels of intoxication during hookups for men but decreasing levels of intoxication for women; and a higher likelihood of being in the riskiest category of having a penetrative hookup, without a condom, while intoxicated. For each of these outcomes, our point estimates for Study 2 fell within the 95% confidence intervals from Study 1. Controlling for trait self-control, binge drinking frequency, broader problematic patterns of alcohol use, openness to experience, and attitudes toward casual sex did not change the pattern of results. Implications for interventions to reduce sexual risk are discussed.

    2013-01-01

    Pyrethroids are popular for use in companion animals due to their relatively low mammalian toxicity and efficacy against arthropods. Nonetheless, pyrethroid intoxication has been reported in cats and dogs, and cats appear to be more susceptible due to difficulty in biotransformation and excretion of pyrethroids. Pyrethroid intoxications are generally due to either the improper use or accidental ingestion of approved products. Methocarbamol, given as intermittent injections, is a common first-line treatment choice for the tremors associated with pyrethroid intoxication. Two cats and one dog were treated with a methocarbamol continuous rate infusion (CRI) for pyrethroid intoxication. Clinical signs of toxicity resolved within a few hr in all three cases, with no adverse drug effects. A methocarbamol CRI can be considered in animals presenting with pyrethroid intoxication.

    We report a paediatric case of survival following severe hydrogen sulfide (H2S) gas intoxication. A 13-year-old boy was found submerged to the neck in a manure tank. He was hypothermic, unresponsive with bilateral mydriasis, and had poor oxygen saturation. After intubation, he was transferred to the paediatric intensive care unit of a tertiary care children's hospital. He developed acute respiratory distress syndrome (ARDS) requiring high frequency percussive ventilation. Cardiac evaluation was significant for myocardial infarction and left ventricular function impairment. He completely recovered from the respiratory and cardiac failure. Neurological examinations showed abnormal signals on MRI in the semi-oval center and in the frontal cortex. Follow-up detected partial impairment of axonal fibers of the right external popliteal sciatic nerve. Paediatric cases of survival after H2S intoxication have been rarely reported. Such exposures can evolve to severe ARDS and benefit from high frequency percussive ventilation. Hypothermia and other metabolic abnormalities are now better explained thanks to actual knowledge about endogenous H2S function. Lessons learned from paediatric accidents should result in better information about this threat for farmers and families living in houses with septic tanks, reducing the risk to their own and their children's safety.

    A case of lead intoxication from an unexpected source is reported. An 18-year-old man came to the Divisin of Safety and Health, New York City, complaining of periodic cramping abdominal pain and weakness of several weeks' duration. In view of clinical laboratory findings, lead intoxication was considered in the differential diagnosis and determination of blood lead and urinary amino levulinic acid (ALA) were done. The blood lead value was 70 ..mu..g/100 g of whole blood. The urinary ALA value was 3.61 mg/100 of creatinine (normal, < 2.0 mg/100 mg of creatinine). A repeated urinary ALA test on the following day gave a value of 3.50 mg/100 mg of creatinine. An industrial hygiene survey was made to ascertain the patient's exposure to lead. The work place was a luncheonette that served flavored fruit drinks. The fruit drinks were dispensed from 12 tanks, and a sampling of these tanks showed that six of them were made of metal and had been soldered in the past. In one tank a chunk of lead was found. An analysis of this chunk of lead revealed that the lead content was 50.1%. Only two of the 12 tanks showed levels of lead that were excessively high; these were made of metal and had been soldered in the past. It was recommended to the owner that acid-containing drinks should be stored in tanks constructed of stainless steel,plastic, or other lead-free materials.

    2009-09-01

    Dextromethorphan is a nonprescription antitussive which has been gaining in popularity as an abused drug, because of the hallucinogenic, dissociative, and intoxicating effects it produces at high doses. This report describes a series of eight drivers arrested for driving under the influence of the combined effects of dextromethorphan and chlorpheniramine, and a further four drivers under the influence of dextromethorphan alone. In the combined dextromethorphan/chlorpheniramine cases, blood dextromethorphan concentrations ranged from 150 to 1220 ng/mL (n = 8; mean 676 ng/mL, median 670 ng/mL), and chlorpheniramine concentrations ranged from 70 to 270 ng/mL (n = 8; mean 200 ng/mL, median 180 ng/mL). The four cases without chlorpheniramine present had blood dextromethorphan concentrations between 190 and 1000 ng/mL (mean 570 ng/mL, median 545 ng/mL). Some drivers had therapeutic concentrations of other drugs present. Drivers generally displayed symptoms of central nervous system (CNS) depressant intoxication, and there was gross evidence of impairment in their driving, including weaving, leaving the lane of travel, failing to obey traffic signals, and involvement in collisions. Drug Recognition Expert opinions confirmed that the subjects were under the influence of a drug in the CNS-depressant category.

  1. Sustained low-efficiency dialysis (SLED) for acute lithium intoxication

    Acute lithium intoxication may cause serious neurologic and cardiac manifestations, up to the patient's death. Owing to its low molecular weight, relatively small volume of distribution close to that of total body water, and its negligible protein binding, lithium can be efficiently removed by any extracorporeal modality of renal replacement therapy (RRT). However, the shift from the intracellular to the extracellular compartment, with the inherent rebound phenomenon after the end of RRT, might limit the efficacy of the conventional, short-lasting haemodialysis. There have been no published studies up to now concerning the use of sustained low-efficiency dialysis (SLED) in lithium intoxication. This report describes a woman with a voluntary acute lithium ingestion of 40 tablets of lithium carbonate (8.12 mEq lithium each). The lithium concentration increased up to 4.18 mEq/l about 24 h after admission, notwithstanding treatment with intravenous crystalloids and gastric lavage. She developed mental status changes, oliguria, hypotension and bradycardia. We started SLED (8 h) with a blood flow of 200 ml/min and countercurrent dialysate flow of 300 ml/min. Lithium serum levels decreased by 86% during treatment, and the patient fully awoke recovering a normal mental status within the first 4 h of treatment. SLED was completed safely within the prescribed time. After the end of treatment, the rebound of lithium concentration was unremarkable. Renal function fully recovered, and the patient was transferred into a psychiatric facility 3 days after admission. PMID:25983926

    We present a substantial series of behavioral and imaging experiments, which demonstrate, for the first time, that increasing AMPA receptor-mediated neurotransmission via administration of potent and selective biarylsulfonamide AMPA potentiators LY404187 and LY451395 reverses the central effects of an acutely intoxicating dose of ethanol in the rat. Using pharmacological magnetic resonance imaging (phMRI), we observed that LY404187 attenuated ethanol-induced reductions in blood oxygenation level dependent (BOLD) in the anesthetized rat brain. A similar attenuation was apparent when measuring local cerebral glucose utilization (LCGU) via C14-2-deoxyglucose autoradiography in freely moving conscious rats. Both LY404187 and LY451395 significantly and dose-dependently reversed ethanol-induced deficits in both motor coordination and disruptions in an operant task where animals were trained to press a lever for food reward. Both prophylactic and acute intervention treatment with LY404187 reversed ethanol-induced deficits in motor coordination. Given that LY451395 and related AMPA receptor potentiators/ampakines are tolerated in both healthy volunteers and elderly patients, these data suggest that such compounds may form a potential management strategy for acute alcohol intoxication.

    Ricinine is an alkaloid present in the castor bean plant (Ricinus communis) that can be used as a biomarker for ricin poisoning. Serial ricinine levels are reported in the serum and urine of a patient suffering from intentional ricin intoxication. The patient was brought to the hospital 4 h after injection and oral intake of a castor bean extract, but died 38 h later, despite intensive medical care. Ricinine was isolated from the samples by solid-phase extraction and quantitatively determined by isotopic dilution liquid chromatography-mass spectrometry. The ricinine level in serum declined from 33 to 23 ng/mL between 10 and 29 h post-exposure. Three urine samples collected from 12 to 41 h after ricin intoxication showed ricinine concentrations in the range of 20-58 ng/mL. The creatinine corrected values (21-30 µg/g) indicated a concentration-time profile with a maximum ricinine level in urine between 12 and 29 h after exposure.

    OBJECTIVES. We examined whether a passive alcohol sensor could be used for mass screening of motorists to accurately and quickly detect drivers whose blood alcohol concentration exceeded a variety of levels often established as per se evidence of legal intoxication. METHODS. In a voluntary roadside survey, 1181 late-night drivers in Minnesota were interviewed. Breath measurements were taken with both a passive alcohol sensor and an evidentiary quality portable breath-test device. RESULTS. Measurements could be taken much more easily and quickly with the passive sensor, whose readings correlated very strongly (r = .87) with the evidentiary device. Moreover, for criterion blood alcohol concentration levels ranging from 100 mg/dL to 20 mg/dL, a large proportion of motorists could be accurately identified as being above or below the criterion, with relatively few false-negative or false-positive identifications. CONCLUSIONS. The use of passive alcohol sensors at sobriety checkpoints should allow motorists to be processed very quickly with minimal inconvenience. At the same time, detection of legally intoxicated motorists will probably be substantially increased and the general deterrent value of per se alcohol-impaired driving laws enhanced. PMID:8460734

    Background Excessive alcohol consumption at licensed alcohol establishments (i.e., bars and restaurants) has been directly linked to alcohol-related problems such as traffic crashes and violence. Historically, alcohol establishments have had a high likelihood of selling alcohol to obviously intoxicated patrons (also referred to as “overservice”) despite laws prohibiting these sales. Given the risks associated with overservice and the need for up-to-date data, it is critical that we monitor the likelihood of sales to obviously intoxicated patrons. Methods To assess the current likelihood of a licensed alcohol establishment selling alcohol to an obviously intoxicated patron, we conducted pseudo-intoxicated purchase attempts (i.e., actors attempt to purchase alcohol while acting out obvious signs of intoxication) at 340 establishments in one Midwestern metropolitan area. We also measured characteristics of the establishments, the pseudo-intoxicated patrons, the servers, the managers, and the neighborhoods to assess whether these characteristics were associated with likelihood of sales of obviously intoxicated patrons. We assessed these associations with bivariate and multivariate regression models. Results Pseudo-intoxicated buyers were able to purchase alcohol at 82% of the establishments. In the fully adjusted multivariate regression model, only one of the characteristics we assessed was significantly associated with likelihood of selling to intoxicated patrons–establishments owned by a corporate entity had 3.6 greater odds of selling alcohol to a pseudo-intoxicated buyer compared to independently-owned establishments. Discussion Given the risks associated with overservice of alcohol, more resources should be devoted first to identify effective interventions for decreasing overservice of alcohol and then to educate practitioners who are working in their communities to address this public health problem.

    Methamphetamine (METH) is a powerful and often-abused stimulant with potent addictive and neurotoxic properties. While it is generally believed that structural brain damage induced by METH results from oxidative stress, in this work we present data suggesting robust disruption of blood-brain and blood-spinal cord barriers during acute METH intoxication in rats. We demonstrate the relationships between METH-induced brain hyperthermia and widespread but structure-specific barrier leakage, acute glial cell activation, changes in brain water and ionic homeostasis, and structural damage of different types of cells in the brain and spinal cord. Therefore, METH-induced leakage of the blood-brain and blood-spinal cord barriers is a significant contributor to different types of functional and structural brain abnormalities that determine acute toxicity of this drug and possibly neurotoxicity during its chronic use.

    The translational capacity of data generated in preclinical toxicological studies is contingent upon several factors, including the appropriateness of the animal model. The primary objectives of this article are: 1) to analyze the natural history of acute and delayed signs and symptoms that develop following an acute exposure of humans to organophosphorus (OP) compounds, with an emphasis on nerve agents; 2) to identify animal models of the clinical manifestations of human exposure to OPs; and 3) to review the mechanisms that contribute to the immediate and delayed OP neurotoxicity. As discussed in this study, clinical manifestations of an acute exposure of humans to OP compounds can be faithfully reproduced in rodents and nonhuman primates. These manifestations include an acute cholinergic crisis in addition to signs of neurotoxicity that develop long after the OP exposure, particularly chronic neurologic deficits consisting of anxiety-related behavior and cognitive deficits, structural brain damage, and increased slow electroencephalographic frequencies. Because guinea pigs and nonhuman primates, like humans, have low levels of circulating carboxylesterases—the enzymes that metabolize and inactivate OP compounds—they stand out as appropriate animal models for studies of OP intoxication. These are critical points for the development of safe and effective therapeutic interventions against OP poisoning because approval of such therapies by the Food and Drug Administration is likely to rely on the Animal Efficacy Rule, which allows exclusive use of animal data as evidence of the effectiveness of a drug against pathologic conditions that cannot be ethically or feasibly tested in humans.

    Paraoxon (POX) is an active metabolite of organophosphate (OP) pesticide parathion that has been weaponized and used against civilian populations. Exposure to POX produces high mortality. OP poisoning is often associated with chronic neurological disorders. In this study, we optimize a rat survival model of lethal POX exposures in order to mimic both acute and long-term effects of POX intoxication. Male Sprague-Dawley rats injected with POX (4 mg/kg, ice-cold PBS, s.c.) produced a rapid cholinergic crisis that evolved into status epilepticus (SE) and death within 6–8 min. The EEG profile for POX induced SE was characterized and showed clinical and electrographic seizures with 7–10 Hz spike activity. Treatment of 100% lethal POX intoxication with an optimized three drug regimen (atropine, 2 mg/kg, i.p., 2-PAM, 25 mg/kg, i.m. and diazepam, 5 mg/kg, i.p.) promptly stopped SE and reduced acute mortality to 12% and chronic mortality to 18%. This model is ideally suited to test effective countermeasures against lethal POX exposure. Animals that survived the POX SE manifested prolonged elevations in hippocampal [Ca2+]i (Ca2+ plateau) and significant multifocal neuronal injury. POX SE induced Ca2+ plateau had its origin in Ca2+ release from intracellular Ca2+ stores since inhibition of ryanodine/ IP3 receptor lowered elevated Ca2+ levels post SE. POX SE induced neuronal injury and alterations in Ca2+ dynamics may underlie some of the long term morbidity associated with OP toxicity. PMID:24785379

    Signs of possible chronic intoxication due to insecticides were sought among 441 apple-growers. A group of 170 persons living in the same environment and 162 other persons having no contact with insecticides were used as controls. It was the first attempt to determine signs of chronic intoxication by organic phosphate and chlorinated hydrocarbon insecticides. The greater incidence of leukopenia and of neurologic manifestations found among the subjects suggest that insecticides may have some chronic effects in man. This assumption is reinforced by the similarities in the findings between the subjects and the environments, and by the parallelism between the duration of exposure to insecticides and the number of affected subjects. The repetition of this study at five-year intervals seems desirable until a sufficient number of apple-growers have been studied who have been exposed to large doses of insecticides for 10, 15 or 20 years.

    The extract from an edible vine, Pueraria lebata, has been reported to be efficacious in lessening alcohol intoxication. In this study, we have tested the efficacy of one of the major components, daidzin, from this plant extract. When ethanol (40% solution, 3 g/kg body weight) was given to fasted rats intragastrically, blood alcohol concentration (BAC) peaked at 30 min after alcohol ingestion and reached 1.77 +/- 0.14 mg/ml (mean values +/- SD, n = 6). If daidzin (30 mg/kg) was mixed with the ethanol solution and given to animals intragastrically, BAC was found to peak at 90 min after alcohol ingestion and reached only 1.20 +/- 0.30 mg/ml (n = 6) (p < 0.05 vs. controls). The ability of daidzin to delay and decrease peak BAC level after ethanol ingestion was also observed in fed animals. In both fasted and fed rats given alcohol without daidzin, BAC quickly declined after reaching its peak at 30 min. By contrast, BAC levels receded more slowly if daidzin was also fed to the animals. Daidzin showed a chronic effect. Rats fed daidzin for 7 days before ethanol challenge, but not on the day of challenge, also produced lower and later peak BAC levels. Interestingly, daidzin, whether fed to rats only once or chronically for 7 days, did not significantly alter activities of either alcohol dehydrogenase or mitochondrial aldehyde dehydrogenase in the liver. Further experiments demonstrated that daidzin shortened sleep time for rats receiving ethanol intragastrically (7 g/kg) but not intraperitoneally (2 g/kg). To test whether daidzin delayed stomach-emptying, [14C]polyethylene glycol was mixed with ethanol and fed to rats.(ABSTRACT TRUNCATED AT 250 WORDS)

    This study aimed to discover potential biomarkers for dioxynivalenol (DON) intoxication. B6C3F1 male mice were orally exposed to 0.83, 2.5 and 7.5 mg/kg body weight (bw) DON for 8 days and the differential protein expressions in their blood plasma were determined by SELDI - Time-of-Flight/Mass Spectrometry (TOF/MS) and the immunoglobulins (Igs) G, A, M and E in the serum were investigated. 11.7 kDa protein was significantly highly expressed according to DON administration and this protein was purified by employing a methyl ceramic HyperD F column with using optimization buffer for adsorption and desorption. The purified protein was identified as a haptoglobin precursor by peptide mapping with using LC/Q-TOF/MS and MALDI-TOF/MS and this was confirmed by western blotting and ELISA. IgG and IgM in serum were decreased in a dose-dependent manner and IgA was decreased at 7.5 mg/kg bw DON administration, but the IgE level was not changed. To compare the expressions of haptoglobin and the Igs patterns between aflatoxin B1 (AFB1), zearalenone (ZEA) and DON intoxications, rats were orally administered with AFB1 1.0, ZEA 240 and DON 7.5 mg/kg bw for 8 days. Haptoglobin was increased only at DON 7.5 mg/kg bw, while it was slightly decreased at ZEA 240 mg/kg bw and it was not detected at all at AFB1 1.0 mg/kg bw. IgG and IgA were decreased by DON, but IgG, IgA, IgM and IgE were all increased by AFB1. No changes were observed by ZEA administration. These results show that plasma haptoglobin could be a diagnostic biomarker for DON intoxication when this is combined with examining the serum Igs. PMID:18716445

    Sodium fluoroacetate (SFAC) is a potent rodenticide, largely used for rodent and domestic pest control. The toxic effects of SFAC are caused by fluoroacetate, a toxic metabolite, whose toxic action blocks the Krebs cycle and also induces the accumulation of citrate in the body, which is a serum calcium chelator. The most common clinical signs of this intoxication are the cardiac and neurological effects. However, the hematological, biochemical and histopathological findings occurring in intoxication are still unknown in different species. In the present study, 16 domestic cats were experimentally intoxicated with oral doses of fluoroacetate (0.45 mg/kg). The hematological and biochemical profiles and histopathological findings were made to look for auxiliary diagnosis methods in SFAC intoxications. The hematological profile showed transitory leucopenia and thrombocytopenia; in the biochemical profiles were detected hyperglycemia, increase of creatinequinase enzyme (CK) and creatinequinase cardiac isoenzyme (CK-MB), hypokalemia and hypophosfatemia. In the macroscopic and histopathological findings were observed lesions characteristic of degenerative and ischemic processes in heart, kidneys, liver, brain and lungs. These changes may be auxiliary to the diagnosis of intoxication by SFAC in cats, when associated with clinical signs described for the species. Thus, the complete blood count with platelet count, serum glucose, enzymes CK and CK-MB isoenzyme, as well as the electrolytes potassium and phosphorus, can facilitate the laboratory diagnosis during intoxication by SFAC, associated with the pathological findings in the case of death of the intoxicated animal.

  15. Event-level associations between objective and subjective alcohol intoxication and driving after drinking across the college years.

    Heavy episodic drinking is strongly associated with driving after drinking, yet there has been mixed evidence regarding whether the disinhibiting effects of alcohol intoxication contribute to the decision to drive after drinking. This investigation tested whether greater alcohol intoxication increased the probability of driving after drinking particularly during drinking episodes in which students experienced reduced subjective feelings of intoxication. A sample of 1,350 college students completed up to 30 days of web-based daily diary monitoring in each of 4 consecutive years. Participants reported daily on their alcohol consumption, subjective intoxication, and whether they drove after drinking on the previous day or night. In generalized estimating equation models, daily estimated blood alcohol concentration (eBAC) was more strongly associated with driving after drinking during episodes in which subjective intoxication was lower. That is, students were most likely to drive after drinking when they were objectively more intoxicated but perceived themselves as less intoxicated. These event-level associations did not change over time nor did they differ as a function of gender. Further, the effects persisted when predicting driving at eBACs above the legal limit for operating a motor vehicle. Greater subjective intoxication may serve to inhibit driving after drinking, particularly when students are objectively more intoxicated. In the absence of subjective intoxication, however, other salient pressures might impel driving after drinking. Prevention efforts should incorporate the importance of variability in subjective intoxication.

    Witnesses to violent crimes are often alcohol intoxicated, but few studies have investigated the impact of alcohol on witness reports. This study investigated how alcohol intoxication and time of interview affected reports of intimate partner violence (IPV). One hundred thirty six healthy men (N = 66) and women (N = 70) were randomized to an alcohol group (0.8g/kg for men, 0.75g/kg for women) (N = 70) or control group (N = 66), given juice. Participants consumed drinks in a laboratory setting before they witnessed an IPV scenario. Fifty percent of the intoxicated and sober participants were interviewed ten minutes after viewing the film and all participants were interviewed one week later. For the analyses, participants in the alcohol group were divided into two groups (moderately/highly intoxicated) based on their BAC-level. Ten minutes after viewing the event, highly (BAC = 0.08-0.15) intoxicated witnesses gave shorter, but as accurate, reports as moderately intoxicated/sober witnesses. All witnesses gave shorter and less accurate reports one week later compared to immediately after. However, an immediate interview increased completeness one week later. In general, time and high intoxication made witnesses give less detailed accounts of actions and verbal information, but not of objects. Highly intoxicated witnesses reported less actions and verbal information in all interviews, while information regarding objects was reported to a similar extent. At the present BAC-level, it is beneficial to conduct an immediate free recall interview with intoxicated witnesses to obtain a maximum amount of correct information and minimize the negative effect of time.

    Introduction: Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxication may be fatal due to perforation or tracheal necrosis. Enteral nutrition is a nutritional method when nutritional substances are administered through specially designed tubing placed through the nose or percutaneously, directly into the GIT. Aim: The aim of this study is to describe the methods of artificial nutrition in patients with acute corrosive intoxications and the importance of nutritional support in the treatment of these intoxications. Discussion: Nutrition in the treatment of acute corrosive intoxications is one of the most important therapeutic processes that largely contribute to faster recovery of the post-corrosive injuries of upper GIT, stabilization of biologic, immunologic and metabolic parameters, and reduction of length of stay in hospital Aim of the treatment of acute corrosive intoxications is to prevent perforation and progressive fibrosis, and esophageal and gastric stenosis. There are different and often conflicting positions, on the conservative treatment of acute corrosive intoxications in adults. Such treatment mainly consists of anti-secretory treatment, antibiotics and intensive hyper-alimentation, aiming to prevent late post-corrosive intoxications. Conclusion: It is considered that nutritional support plays a major role in maintenance of metabolic processes and prevention of severe metabolic complications that could additionally aggravate the condition and impair the treatment.

    Marine and coastal regions provide a diverse range of foods and serve as recreation and leisure areas for large numbers of people in many parts of the world. However, they also serve as environments associated with numerous hazards. The number of cases of fish- and shellfish-related food poisonings in the United States has increased in recent years, accounting for over 600,000 illnesses, with 3,000 hospitalizations and 94 deaths annually. Human diseases due to pathogenic Vibrio species can result from both ingestion of contaminated shellfish and exposure of open wounds to contaminated seawater. A variety of infections may result from human interactions with marine life, including sharks, barracudas, and moray eels. This chapter covers some of the risks of the shore, including fish and shellfish intoxications, infections related to Vibrio species, and infections resulting from marine trauma.

    We report the case of a 69-year-old woman with seizures and acute renal failure with hyperkalemia. She presented with bladder turgescence and hydronephrosis on admission and was diagnosed as obstructive acute renal failure. Urethral catheterization was performed after a single-session hemodialysis. It resulted in immediate improvement of renal function and consciousness, and subsequent disappearance of seizures. Improvement of serum creatinine level to 0.7 from 10.6 mg/dL was associated with a fall in blood level of amantadine hydrochloride from 4.40 to 0.47 microg/mL. Physicians should be aware of urinary retention in patients treated with amantadine as a first sign of intoxication that could lead if untreated to obstructive acute renal failure. And we recommend to check the overdose symptoms, even those with normal renal function, treated with amantadine.

    1998-09-01

    This article deals with the question in how far an offence committed in the Netherlands under the influence of alcohol or other drugs can be imputed to the offender. Unlike many other countries the Dutch Penal Code does not contain specific provisions with respect to the criminal liability of addicted or intoxicated offenders. In principle, they are held responsible for their offences, even when the dolus or culpa is absent at the moment they commit their offence. Doctrine and jurisprudence found this liability on the principle of 'culpa/dolus in causa', by accepting an anterior dolus or culpa, which is situated at the moment the offender takes alcohol or other drugs. As is shown in this article, the - nondogmatic - interpretation of this culpa in causa doctrine leaves hardly any space for a claim to impunity.

    Possible mechanisms of the antitoxic action of organoselenium compounds in heavy metal poisoning have been considered. Heavy metal toxicity associated with intensification of free radical oxidation, suppression of the antioxidant system, damage to macromolecules, mitochondria and the genetic material can cause apoptotic cell death or the development of carcinogenesis. Organic selenium compounds are effective antioxidants during heavy metal poisoning; they exhibit higher bioavailability in mammals than inorganic ones and they are able to activate antioxidant defense, bind heavy metal ions and reactive oxygen species formed during metal-induced oxidative stress. One of promising organoselenium compounds is diacetophenonyl selenide (DAPS-25), which is characterized by antioxidant and antitoxic activity, under conditions including heavy metal intoxication.

    During April and June 2008, we investigated three outbreaks of marine puffer fish intoxication in three districts of Bangladesh (Narshingdi, Natore, and Dhaka). We also explored trade of marine puffer fish in Cox's Bazaar, a coastal area of the country. We identified 95 people who had consumed puffer fish; 63 (66%) developed toxicity characterized by tingling sensation in the body, perioral numbness, dizziness, and weakness, 14 of them died. All three outbreaks were caused by consumption of large (0.2-1.5 kg) marine puffer fish, sold in communities where people were unfamiliar with the marine variety of the fish and its toxicity. Coastal fishermen reported that some local businessmen distributed the fresh fish to non-coastal parts of the country, where people were unfamiliar with the larger variety, to make a quick profit. Lack of knowledge about marine puffer toxicity contributed to the outbreaks. Health communication campaigns will enhance people's knowledge and may prevent future outbreaks.

    Sodium azide (NaN3) is an inorganic matrix compound with a very high toxicity. Mechanism of action is not clarified, and it is assumed to interfere with the processes of oxidative phosphorylation. The acute intoxications with sodium azide are extremely rare. We described a case of 19-year-old man who was found dead. In the course of prosecution the empty container, with label "NaN3, 20 g", was found near the body. There were traces of white powder detected in the container. Azide ions were determined by derivatization, i.e. they were transformed to pentafluorobenzaldehyde azide compound. Analysis of the final extract after derivatization was performed by gas chromatography coupled with mass spectrometry GC/MS. The largest concentration of azide ions were determined in the stomach content and vitreous humour, and much less one in whole blood, urine and kidney fluid.

    This study examined the association between proximal vs. distal effect expectancies for cocaine consumption in a college student population with (N = 26) and without (N = 69) cocaine experience. Participants completed the Cocaine Effect Expectancy Questionnaire-Likert (CEEQL) and were asked to respond to each item twice: first, their belief about that specific effect during the initial phase of cocaine intoxication; and second, in relation to their belief about that effect during the descendent period. Positive and negative scales were scored for each subject. Positive expectancies were not associated between the two time points, while negative expectancies were. Users reported significantly less negative expected effects of cocaine, while nonusers and users held similar beliefs about the positive effects of cocaine. This latter effect was replicated in an independent sample (N = 140).

    Tapentadol (Nucynta) is a centrally acting opioid analgesic prescribed for the treatment of moderate to severe acute pain. Its efficacy is believed to be due to μ-opioid receptor agonist activity and inhibition of norepinephrine reuptake resulting in increased norepinephrine concentrations. There is only one other case in the literature relating to the toxicity of this agent or report of a fatality. This case report documents a case in which tapentadol was identified as the cause of death. The tapentadol concentration found in the heart blood submitted in this case was more than 20 times the upper limit of the therapeutic range. Possible mechanisms of death include respiratory depression, central nervous system depression, and serotonin syndrome. Based on the scene investigation and autopsy findings in this case, the medical examiner determined that the cause of death was narcotic (Nucynta) intoxication and the manner of death was undetermined.

    The perception of prairie dogs (Cynomys spp.) both as a nuisance species and a keystone species presents a significant challenge to land, livestock, and wildlife managers. Anticoagulant and nonanticoagulant rodenticides are commonly employed to control prairie dog populations throughout their range. Chlorophacinone, and to a lesser extent zinc phosphide, are widely used in northwestern Kansas for controlling black-tailed prairie dog (Cynomys ludovicianus) populations. Although zinc phosphide poisoning of gallinaceous birds is not uncommon, there are few published accounts of nontarget chlorophacinone poisoning of wildlife. We report three mortality events involving nontarget rodenticide poisoning in several species, including wild turkeys (Meleagris gallopavo), a raccoon (Procyon lotor), and an American badger (Taxidea taxus). This includes the first documentation of chlorophacinone intoxication in wild turkeys and an American badger in the literature. The extent of nontarget poisoning in this area is currently unknown and warrants further investigation.

    Two girls, 16 and 18 years old, with anorexia nervosa developed generalized convulsion as a result of drinking excessive amounts of water. The neurological symptoms disappeared, but the girls held on to their excessive drinking habits, despite psychoeducation. Although fluid restriction is known to be a major problem for anorexia nervosa patients within the context of extreme fasting, one should realize that these patients can also run the risk of water intoxication following excessive water intake. Therefore all patients should be questioned explicitly about their daily fluid intake. In the case of polydipsia, the patient's blood should be tested and serum electrolytes should be measured. Patients should be given psychoeducation in order to make them more aware of the possible dangers of excessive water intake.

    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.

    Les intoxications aiguës par les pesticides organophosphorés (OP) au cours de la grossesse sont des événements rares, peu décrites dans la littérature. A travers cette étude rétrospective, nous rapportons les résultats de sept cas d’ingestion suicidaire d’OP chez des femmes enceintes. Cette intoxication était le plus souvent grave. En effet, cinq des sept parturientes avaient un Glasgow initial < 9 et le POP score était ≥ 3 chez toutes les parturientes. Cinq patientes avaient nécessité une ventilation mécanique de durée moyenne de 3,4 jours. L’évolution était favorable pour toutes les patientes mais dans plus de la moitié des cas elle était défavorable pour le fœtus (mort fœtal in utéro). Deux mécanismes peuvent expliquer ces complications fœtales. Le premier est l’hypoxie fœtale associée ou non à un état de choc qui peuvent se traduire au niveau du RCF par une tachycardie ou des décélérations et aboutir ainsi à un décès in utero. Le deuxième mécanisme est le passage de ces pesticides à travers la barrière placentaire, ce qui pose un risque potentiel pour le fœtus par altération des systèmes enzymatiques des microsomes.

    The effect of ingestion of dried leaves of Cestrum diurnum, a plant shown to contain a 1,25-dihydroxycholecalciferol-like principle, was tested in normal pigs fed 1.2% calcium and 1.0% phosphorus for 10 weeks from weaning and in hyperparathyroid pigs fed 0.8% calcium and 1.6% phosphorus for the same periods of time. Addition of 3% Cestrum diurnum leaf meal rapidly resulted in decreased feed consumption and weight gain, hypercalcemia and hypophosphatasemia. In normal pigs, plasma calcium rose to 16 mg/100 ml within one week and remained high for the 4 week experimental period. In hyperparathyroid pigs with hypocalcemia, plasma calcium rose to 12.75 mg/100 ml within one week and later approached 15 mg/100 ml. Ingestion of Cestrum diurnum retarded cell differentiation of growth cartilages. Arrested osteocytic osteolysis was observed within one week with osteopetrosis of epiphyses and metaphyses. The negative effect on the resorbing osteocytes then caused osteonecrosis which, in combination with lack of bone formation because of atrophy of osteoblasts, resulted in osteopenia within 4 weeks. Dystrophic calcinosis occurred within 2 weeks and was widespread after 4 weeks in lungs, kidneys, heart and vessels. Atrophy of parathyroid cells was severe after one week. Hyperparathyroid pigs responded with skeletal lesions, dystrophic calcinosis and parathyroid atrophy more rapidly and severely than normal pigs. The biochemical and anatomical changes in Cestrum diurnum ingestion are closely similar to those in vitamin D3 intoxication in pigs. Whereas pigs can tolerate large amounts of vitamin D3 because of feed-back control of 1 alpha-hydroxylation in the kidney, this control point is by-passed in Cestrum diurnum ingestion and intoxication occurs promptly.

    Cytochrome c oxidase (CCO), a mitochondrial enzyme, is inactivated by cyanide or carbon monoxide (CO) intoxication. We measured CCO activity, in the major organs of the rat at various times after death caused by cyanide intoxication. Tissue samples were homogenized, and the CCO activity in the mitochondrial fraction was measured using ferrous cytochrome c as the substrate. The CCO activity inhibition was highest in the brain, although the cyanide concentration was lowest level. As a result of this and the clinical symptoms displayed, we consider the brain to be the primary organ of cyanide intoxication. As cyanide is highly toxic to humans, in small amounts and many patients and victims have already had some medical care, it is difficult to detect cyanide in criminal investigations. The CCO activities in various organs remained significantly low for 2 days after the cyanide intoxication, suggesting that the diagnosis may be possible by measuring not only the cyanide concentration but also the CCO activity.

    Most of the reports of oxalic acid intoxication are in cases of ethylene glycol intoxication. These symptoms are known to be central nerve system manifestations, cardiopulmonary manifestations and acute renal failure. There have been only a few reports of direct oxalic acid intoxication. However, there have been a few recent reports of oxalic acid intoxication due to the ingestion of star fruit and ascorbic acid. We herein report the case of a patient with acute renal failure and metabolic acidosis caused directly by consumption of oxalic acid. During the initial examination by the physician at our hospital, the patient presented with tachypnea, a precordinal burning sensation, nausea and metabolic acidosis. After admission, the patient developed renal failure and anion gap high metabolic acidosis, but did not develop any CNS or cardio-pulmonary manifestations in the clinical course. The patient benefitted symptomatically from hemodialysis.

    Objectives Alcohol misuse has been widely studied as a substantial contributor to injured patients' visits to emergency departments. The current research studied differences in alcohol-related injury variables in China and Korea. Methods Data were collected from a sample of 4,509 patients (2,862 males and 1,667 females) reporting at emergency departments in China and Korea using the World Health Organization collaborative study on alcohol and injuries protocol. Results More injuries were reported by men, young people aged 25–34 years, employed individuals, and persons who had at least a high-school education. The proportion of injury cases among intoxicated patients was 14% for Chinese and 20% for Koreans. The odds of intentional injuries to intoxicated patients increased significantly when the perpetrator had been drinking, especially for severely intoxicated victims in both countries. The odds of injuries for intoxicated persons in both countries were high during sports and leisure activities; odds ratio (OR) = 3.93, 95% confidence interval (CI) = 2.76–5.59 for Chinese and OR = 10.97, 95% CI = 6.06–19.85 for Koreans. Conclusion These findings are a contribution to research in the two Asian countries about the effect of intoxication on injuries especially when both victim and perpetrator are intoxicated.

    Background Perception of alcohol intoxication presumably plays an important role in guiding behavior during a current drinking episode. Yet, there has been surprisingly little investigation of what aspects associated with intoxication are used by individuals to attribute their level of intoxication. Methods Building on recent laboratory-based findings, the current study employed a complex field-based design to explore the relative contributions of motor performance versus cognitive performance – specifically executive control – on self-attributions of intoxication. Individuals recruited outside of bars (N = 280; mean age = 22; range: 18–32) completed a structured interview, self-report questionnaire, and neuropsychological testing battery, and provided a breath alcohol concentration (BrAC) sample. Results Results of a multiple linear regression analysis demonstrated that current level of subjective intoxication was associated with current alcohol-related stimulant effects, current sedative effects, and current BrAC. After controlling for the unique variance accounted for by these factors, subjective intoxication was better predicted by simple motor speed, as indexed by performance on the Finger Tapping Test, than by executive control, as indexed by performance on the Trail Making Test. Conclusions These results – generated from data collected in a naturally occurring setting – support previous findings from a more traditional laboratory-based investigation, thus illustrating the iterative process of linking field methodology and controlled laboratory experimentation.

    Human stability control is a complex process comprising contributions from several partly independent mechanisms such as coordination, feedback and feed-forward control, and adaptation. Acute alcohol intoxication impairs these functions and is recognized as a major contributor to fall traumas. The study aimed to investigate how alcohol intoxication at .06% and .10% blood alcohol concentration (BAC) affected the movement spans and control of posture alignment. The angular positions of the head, shoulder, hip and knees relative to the ankles were measured with a 3D motion analysis system in 25 healthy adults during standing with eyes open or closed and with or without vibratory balance perturbations. Alcohol intoxication significantly increased the movement spans of the head, shoulders, hip and knees in anteroposterior and lateral directions during quiet stance (p < or = .047 and p < or = .003) and balance perturbations (p<.001, both directions). Alcohol intoxication also decreased the ability to reduce the movement spans through adaptation in both anteroposterior (p < or = .011) and lateral (p < or = .004) directions. When sober and submitted to balance perturbations, the subjects aligned the head, shoulders, hip and knees more forward relative to the ankle joint (p < .001), hence adopting a more resilient posture increasing the safety margin for backward falls. Alcohol intoxication significantly delayed this forward realignment (p < or = .022). Alcohol intoxication did not cause any significant posture realignment in the lateral direction. Thus, initiation of adaptive posture realignments to alcohol or other disruptions might be context dependent and associated with reaching a certain level of stability threats.

    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.

    Introduction. In this paper, we aimed to present five Papaver rhoeas intoxication cases, which is very rare in the literature. Case 1. A 35-year-old female patient was admitted to our emergency room with the complaints of nausea, restlessness, and dyspnea developing 3 hours after eating Papaver rhoeas. On physical examination, her general condition was moderate; she was conscious and the vital findings were normal. The pupils were myotic. She was transferred to the toxicology intensive care unit as she experienced a generalized tonic clonic seizure lasting for three minutes. Case 2. A 41-year-old female patient was brought to our emergency room by 112 ambulance as she had contractions in her arms and legs, unconsciousness, and foam coming from her mouth two hours after Papaver rhoeas ingestion. On physical examination, she was confused, the pupils were myotic, and she was tachycardic. Arterial blood gases analysis revealed lactic acidosis. Case 3. A 38-year-old female patient was admitted to our emergency room with complaints of nausea and vomiting two hours after ingestion of Papaver rhoeas. Her physical examination and tests were normal. Case 4. A 34-year-old male patient was admitted to our emergency room with complaints of numbness and loss of power in his arms and legs one hour after Papaver rhoeas ingestion. He was hospitalized at the toxicology intensive care unit for follow-up and treatment. Dyspnea and bradycardia developed on the follow-up. The oxygen saturation without oxygen support was 90%. ECG revealed sinus bradycardia. The cardiac enzymes did not increase. Case 5. A 42-year-old female patient was brought to our emergency room by 112 ambulance with contractions in her arms and legs and unconsciousness two hours after Papaver rhoeas ingestion. On her physical examination, she was confused and the pupils were myotic. Arterial blood gases analysis revealed lactic acidosis. Conclusion. All patients were followed up for a few days and then discharged from

    Elevated levels of naturally occurring uranium have been found in small geographic areas throughout the world. Exposure of the general public to uranium is most often by the ingestion of food and water containing natural uranium from the hydrogeological environment, but this likelihood is remote. However, the risk is increased in regions where uranium is mined, milled, processed and/or fabricated as well as in the vicinity of former battlefields where depleted uranium munitions were deployed. Exposure in such cases is by the inhalation route. Internalized uranium is a long-term hazard the toxicity of which depends upon the dose and the dose rate as well as other parameters such as the chemical form and site of deposition of the uranium and the physiology of the host. The radiological toxicity and the chemical toxicity of uranium and its compounds are responsible for kidney damage and lung cancer. The vulnerable groups are the very young and the very old, individuals predisposed to hypertension or osteoporosis and individuals with chronic kidney disease. Those subject to long-term exposure from internalized uranium are a greater risk for the long-term implications. The accumulation of uranium may be mitigated by decreasing its absorption, distribution and deposition and increasing its elimination with chelating agents. The formation of soluble chelates may enhance the mobilization of uranium deposited in tissue and expedite its transport to and elimination from the renal system. The focus of this review is on the use of chelating agents to enhance decorporation of uranium thereby reducing the risk of intoxication.

    Les pyréthrinoïdes sont des insecticides largement utilisés du fait de leur efficacité et de leur relative sécurité chez l'homme. Les intoxications mortelles liées à ces agents restent exceptionnelles. Leur métabolisme hépatique rapide limite considérablement leur toxicité chez l'homme. Cette observation relate une intoxication grave à un pyréthrinoïde (la cyperméthrine) dont le solvant était l'éthylène glycol. Ce dernier est un toxique nettement plus dangereux pour l'homme. Le tableau clinique consistait en une atteinte multiviscérale avec prédominance de la défaillance cardiovasculaire et neurologique. Le faible potentiel toxique des pyréthrinoïdes suggère l'implication évidente de l'éthylène glycol dans la gravité de cette intoxication. La prise en charge thérapeutique, essentiellement symptomatique, n'a pas pris en compte la présence d'éthylène glycol dans la formulation de l'insecticide. L'évolution clinique était défavorable. Devant toute intoxication grave à un insecticide pyréthrinoïde une intoxication associée au solvant tel que l'éthylène glycol doit être recherchée et traitée. PMID:23734273

    Toxic effect of 50% ethanol solution (8 g/kg) on the heart appeared as diminishment of contractile properties of the myocardium. Structural GABA-analogues - citrocard (50 mg/kg), phenibut (50 mg/kg) and pyracetam (200 mg/kg) prevented injurious action of alcohol. This was evidenced by higher indices of contraction and relaxation velocity, and left ventricular pressure in intervention groups of animals compared with controls during functional tests with volume and maximal isometric load.

    Seventy female Wistar rats 90 to 100 g, were separated into eight groups according to three levels of vitamin D added to their diet (0, 1, and 5 IU/100 g of diet), two levels of cadmium (0 and 10 mg/100 g of diet), and the route - oral or subcutaneous - for administration of cadmium. After 500 days, the rats were killed and examined histologically and biochemically. Remarkable abnormalities were observed in the femurs and kidneys in cadmium-treated rats. Abnormal osteoplasic with formation of osteoid tissue were observed in both cadmium-treated, vitamin D-adequate rats, and vitamin D-deficient control rats. Renal lesions in the cadmium-treated rats were localized in tubules and the glomeruli were almost normal. The lowering of plasma calcium levels and the increase of urinary excretion of total protein, lysozyme, and calcium were observed in the cadmium-treated, vitamin D-adequate rats. Calcium concentrations in livers and femurs were decreased in both cadmium-treated rats and vitamin D-deficient control rats. The conclusion of the present work is that cadmium exposure over a long period could induce the same findings in bones and plasma as those of nutritional vitamin D deficiency.

    Background The 21st-century epidemic of pharmaceutical and other drug-intoxication deaths in the United States (US) has likely precipitated an increase in misclassified, undercounted suicides. Drug-intoxication suicides are highly prone to be misclassified as accident or undetermined. Misclassification adversely impacts suicide and other injury mortality surveillance, etiologic understanding, prevention, and hence clinical and public health policy formation and practice. Objective To evaluate whether observed variation in the relative magnitude of drug-intoxication suicides across US states is a partial artifact of the scope and quality of toxicological testing and type of medicolegal death investigation system. Methods This was a national, state-based, ecological study of 111,583 drug-intoxication fatalities, whose manner of death was suicide, accident, or undetermined. The proportion of (nonhomicide) drug-intoxication deaths classified by medical examiners and coroners as suicide was analyzed relative to the proportion of death certificates citing one or more specific drugs and two types of state death investigation systems. Our model incorporated five sociodemographic covariates. Data covered the period 2008–2010, and derived from NCHS’s Multiple Cause-of-Death public use files. Results Across states, the proportion of drug-intoxication suicides ranged from 0.058 in Louisiana to 0.286 in South Dakota and the rate from 1 per 100,000 population in North Dakota to 4 in New Mexico. There was a low correlation between combined accident and undetermined drug-intoxication death rates and corresponding suicide rates (Spearman’s rho = 0.38; p<0.01). Citation of 1 or more specific drugs on the death certificate was positively associated with the relative odds of a state classifying a nonhomicide drug-intoxication death as suicide rather than accident or undetermined, adjusting for region and type of state death investigation system (odds ratio, 1.062; 95% CI,1.016

    1994-02-01

    The reliance of current advocates of recreational drug legalization on parallels between "drug prohibition" and the repudiated experiment of National Prohibition in the 1920s invites renewed attention to the history of the legalization and normalization of drinking. A new scientific conception of the nature and effects of alcohol formed an important element in both the politics of repeal and the ensuing legitimation of alcohol consumption. The industrial toxicologist Yandell Henderson argued that alcohol should be considered analogous to carbon monoxide--clearly a poison, yet a normal part of civilized life and only problematic above a determinable and manageable exposure threshold. This argument had political force in the early 1930s as part of the contention that beer was not an "intoxicating liquor." It was more broadly persuasive because it was consistent with Americans' experience with industrial poisons, for which exposure levels had been set by toxicologists such as Henderson. This historical perspective illuminates the more recent reassessment of the risks of alcohol consumption. It also challenges the applicability of the model of the normalization of drinking to proposals to legalize cocaine and opiates.

    When clinicians treat patients with pesticide poisoning, they often pay attention only to the chief toxic agent and ignore the toxicity of the pesticide's additives or solvents. Occasionally, however, a solvent (e.g. methanol) may itself be the cause of poisoning. We report a case of acute methanol intoxication that occurred after ingestion of a methomyl pesticide that contained methanol as an additive. A 49-year-old man was brought to the emergency department in an unconscious state after ingestion of 20 ml of a carbamate pesticide (chief ingredient: methomyl; active ingredient: methanol). Upon arrival, he was semicomatose and did not breathe spontaneously; however, his cholinesterase level was within normal limits and cholinergic symptoms were not observed. High anion gap metabolic acidosis was present. His blood ethanol level was 74.8 mg/dL. The urine methanol level was 55.60 mg/dL, and urine ethanol level was 22.0 mg/dL. He was treated with hemodialysis; subsequently, his metabolic acidosis resolved and he returned to normal mental status. We guessed that methanol, as the solvent of the methomyl, had produced the symptoms. When treating pesticide-poisoned patients, clinicians should identify the solvent used in the pesticide, because solvents such as methanol may exacerbate the symptoms of poisoned patients.

  11. The mechanism of cyanide intoxication and its antagonism.

    The mechanism of cyanide intoxication has been attributed to the inhibition of cytochrome oxidase, thereby decreasing the tissue utilization of oxygen. One mechanism of cyanide antagonism is by sequestering cyanide with methaemoglobin to form cyanmethaemoglobin and another mechanism is detoxifying with a sulphur donor to thiocyanate. Questions have been raised with regard to these classical mechanisms. Oxygen with nitrite-thiosulphate antagonizes the lethal effects of cyanide. Theoretically, increased oxygen should serve no useful purpose, as it is the tissue utilization of oxygen which is inhibited. In the nitrite-thiosulphate antidotal combination, the proposal is made that the predominate antidotal action of nitrite is a vasogenic action, rather than methaemoglobin formation, because when methaemoglobin formation is inhibited by methylene blue the protective action of sodium nitrite persists. This suggests that methaemoglobin formation plays only a small part, if any, in the therapeutic antagonism of the lethal effects of cyanide. The roles and implications of sodium thiosulphate and non-rhodanese substrates in the detoxification mechanism are compared. Lastly, a new approach to cyanide antagonism has been initiated which involves the erythrocyte encapsulation of thiosulphate and sulphurtransferase as an antidote and prophylaxis against cyanide.

    Cyanide is a ubiquitous chemical in the environment and has been associated with many intoxication episodes; however, little is known about its potentially toxic effects on development. The aim of this study was to evaluate the effects of maternal exposure to potassium cyanide (KCN) during pregnancy on both sows and their offspring. Twenty-four pregnant sows were allocated into four groups that orally received different doses of KCN (0.0, 2.0, 4.0, and 6.0 mg/kg of body weight) from day 21 of pregnancy to term. The KCN-treated sows showed histological lesions in the CNS, thyroid follicle enlargement, thyroid epithelial thickening, colloid reabsorption changes, and vacuolar degeneration of the renal tubular epithelium. Sows treated with 4.0 mg/kg KCN showed an increase in the number of dead piglets at birth. Weaned piglets from all KCN-treated groups showed histological lesions in the thyroid glands with features similar to those found in their mothers. The exposure of pregnant sows to cyanide thus caused toxic effects in both mothers and piglets. We suggest that swine can serve as a useful animal model to assess the neurological, goitrogenic, and reproductive effects of cyanide toxicosis.

    The detoxification of hydrogen sulfide (H/sub 2/S) by a heme catalyzed oxidation was examined as part of an on-going study of H/sub 2/S toxicity. Interlocking O/sub 2/ absorption and sulfide depletion data indicate that both oxyhemoglobin and methemoglobin are effective catalytic agents. Although the latter is more efficacious, the life time of excess sulfide in the presence of oxygen and either of the above is of the order of minutes. It has also been established that the formation of methemoglobin following nitrite administration occurs preferentially under oxygen poor conditions. Under an atmospheric or oxygen enriched environment, which favors sulfide depletion, the nitrite retards sulfide oxidation. Thus nitrite as an antidote for acute H/sub 2/S intoxication can only be effective within the first few minutes after the exposure, at which time resuscitation and/or ventilation of the victim is likely to produce conditions in which the nitrite actually slows sulfide removal.

    Amitriptyline is a tricyclic antidepressant widely used in the treatment of depression. Antidepressant drugs are among the most commonly encountered causes of self-poisoning, as illustrated by several published cases in the literature. This investigation reports a case of massive amitriptyline intoxication, involving a 44-year old female found dead in bed. The presence of this tricyclic antidepressant was revealed by a routine screening procedure. The concentration was calculated by gas chromatography/ electron ionization-mass spectrometry in the selected ion monitoring mode after solid-phase extraction using proadifen as internal standard and was in the post-mortem whole blood sample 85.9 mug/mL. This value was much higher than the reported toxic values ever found in the literature, and may therefore have caused the victim's death. Nortriptyline was also detected in the toxic concentration range, as well as therapeutic levels of diazepam and nor-diazepam. Taking into account both the available circumstantial information and toxicological results, it is very likely that death was caused by self-poisoning.

  15. Is liquor intoxicating? Scientists, prohibition, and the normalization of drinking.

    The reliance of current advocates of recreational drug legalization on parallels between "drug prohibition" and the repudiated experiment of National Prohibition in the 1920s invites renewed attention to the history of the legalization and normalization of drinking. A new scientific conception of the nature and effects of alcohol formed an important element in both the politics of repeal and the ensuing legitimation of alcohol consumption. The industrial toxicologist Yandell Henderson argued that alcohol should be considered analogous to carbon monoxide--clearly a poison, yet a normal part of civilized life and only problematic above a determinable and manageable exposure threshold. This argument had political force in the early 1930s as part of the contention that beer was not an "intoxicating liquor." It was more broadly persuasive because it was consistent with Americans' experience with industrial poisons, for which exposure levels had been set by toxicologists such as Henderson. This historical perspective illuminates the more recent reassessment of the risks of alcohol consumption. It also challenges the applicability of the model of the normalization of drinking to proposals to legalize cocaine and opiates. Images p307-a p309-a PMID:8296962

  16. Food-borne infections and intoxications in Europe*

    Any attempt to evaluate the prevalence of food-borne diseases in Europe is fraught with difficulty, partly because in some countries such diseases, if reported, are not clearly designated as food-borne, and partly because of the variety in terminology and methods of classification. Nevertheless, it is apparent that, although certain food-borne infections have decreased in prevalence, others have increased during the past decade. This increase has been shown to be related in some countries to the import of certain foodstuffs and fodder from tropical and subtropical regions and has resulted in a general spread of Salmonella infections by a wide variety of serotypes. Food-borne intoxications are predominantly caused by the ingestion of the toxins elaborated by the growth of Staphylococcus aureus in food and by spore-forming bacilli. Botulism is now rare in Europe. While the recent increase in the prevalence of these diseases calls for strict supervision of food products and improved measures of ensuring food hygiene, the efficacy of such steps as may be taken will depend on close co-operation between public health and veterinary public health authorities.

  17. Studies of antidote therapy for nisoldipine intoxication in experimental animals.

    Strubelt, O; Diederich, K W

    1990-07-01

    In anesthetized rats under artificial respiration, intravenous infusion of nisoldipine (0.1 mg/kg x min) caused significant decreases in blood pressure, heart rate, cardiac output and peripheral resistance. The animals died 54.7 +/- 11.1 min after initiation of the infusion. The electrocardiogram showed sinus bradycardia, increasing AV blockade and displacement of the pacemaker into the AV node or the bundle of His. Survival time under nisoldipine infusion increased more than two-fold with simultaneous infusion of calcium gluconate, isoprenaline (isoproterenol) or dopamine. Norepinephrine (noradrenaline) had no significant effect on survival time; the latter decreased to 19.4 +/- 1.6 min by plasma volume expansion with polygeline. All antidotes prolonging survival time also normalized the cardiac output diminished after nisoldipine. Electrocardiographic changes were antagonized only by isoprenaline. Suitable antidotes for intoxication or over-dosage of nisoldipine are calcium salts as well as beta-sympathomimetic drugs; sheer volume substitution and peripheral vascular constriction should not be resorted to.

    Cyanide is a ubiquitous chemical in the environment and has been associated with many intoxication episodes; however, little is known about its potentially toxic effects on development. The aim of this study was to evaluate the effects of maternal exposure to potassium cyanide (KCN) during pregnancy on both sows and their offspring. Twenty-four pregnant sows were allocated into four groups that orally received different doses of KCN (0.0, 2.0, 4.0, and 6.0 mg/kg of body weight) from day 21 of pregnancy to term. The KCN-treated sows showed histological lesions in the CNS, thyroid follicle enlargement, thyroid epithelial thickening, colloid reabsorption changes, and vacuolar degeneration of the renal tubular epithelium. Sows treated with 4.0 mg/kg KCN showed an increase in the number of dead piglets at birth. Weaned piglets from all KCN-treated groups showed histological lesions in the thyroid glands with features similar to those found in their mothers. The exposure of pregnant sows to cyanide thus caused toxic effects in both mothers and piglets.

    Paraquat (PQ) has known negative human health effects, but continues to be commonly used worldwide as a herbicide. Our clinical data shows that the main prognostic factor is the time required to achieve a negative urine dithionite test. Patient survival is a 100% when the area affected by ground glass opacity is <20% of the total lung volume on high-resolution computed tomography imaging 7 days post-PQ ingestion. The incidence of acute kidney injury is approximately 50%. The average serum creatinine level reaches its peak around 5 days post-ingestion, and usually normalizes within 3 weeks. We obtain two connecting lines from the highest PQ level for the survivors and the lowest PQ level among the non-survivors at a given time. Patients with a PQ level between these two lines are considered treatable. The following treatment modalities are recommended to preserve kidney function: 1) extracorporeal elimination, 2) intravenous antioxidant administration, 3) diuresis with a fluid, and 4) cytotoxic drugs. In conclusion, this review provides a general overview on the diagnostic procedure and treatment modality of acute PQ intoxication, while focusing on our clinical experience.

    The curiosity and the natural tendency to explore the environment put young children at an increased risk of poisoning over older children and adults. Poisonings are a significant area of concern from 1 year of age and progressively contribute more to overall rates of morbidity and mortality until children reach adulthood. Particularly, the abuse of children by poisoning is also highly common with thousands of fatalities. A practical strategy is presented that aims to alert health, forensic, and law enforcement professionals to this problem and to demystify the preconception that it is a rare form of abuse or neglect. Compounds that are foreign to a living organism (xenobiotics) and those present within body (endobiotics), mainly involved in children intoxications and contextual examples related to exposure are also reviewed. Particular concern is given to concepts in the field of children poisoning. The described history and the clinical and toxicological evaluation are discussed, and harmonized protocols regarding correct procedures for sample collection to forensic toxicological analysis are proposed. Since children are particularly vulnerable to the toxic effects of high doses of xenobiotics and endobiotics, special consideration on the preparation of the environment that surrounds children in order minimize all possible risks will be also considered.

    The present review provides an update of the general principles for the investigation and use of chelating agents in the treatment of intoxications by metals. The clinical use of the old chelators EDTA (ethylenediamine tetraacetate) and BAL (2,3-dimercaptopropanol) is now limited due to the inconvenience of parenteral administration, their own toxicity and tendency to increase the neurotoxicity of several metals. The hydrophilic dithiol chelators DMSA (meso-2,3-dimercaptosuccinic acid) and DMPS (2,3-dimercapto-propanesulphonate) are less toxic and more efficient than BAL in the clinical treatment of heavy metal poisoning, and available as capsules for oral use. In copper overload, DMSA appears to be a potent antidote, although d-penicillamine is still widely used. In the chelation of iron, the thiols are inefficient, since iron has higher affinity for ligands with nitrogen and oxygen, but the new oral iron antidotes deferiprone and desferasirox have entered into the clinical arena. Comparisons of these agents and deferoxamine infusions are in progress. General principles for research and development of new chelators are briefly outlined in this review.

    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.

    In this report we consider the possibility that speech analysis techniques may be used to determine whether an individual was intoxicated at the time that a voice recording was made, and discuss an analysis of the speech produced by the captain of the Exxon Valdez recorded at several points around the time of the accident at Prince William Sound, Alaska. A review of previous research on the effects of alcohol and other effects on speech production suggests that it may be possible to attribute a certain, unique pattern of changes in speech to the influence of alcohol. However, the rate of occurrence of this pattern or the reliability of a decision based on observations such as these is not known. Acoustic-phonetic analysis of a small number of tokens of Captain Hazelwood’s speech recorded before, during and after the accident revealed a number of changes in speech behavior which are similar to the pattern of changes observed in previous laboratory-based research on the effects of alcohol on speech production. We conclude with a discussion of the limitations in making inferences concerning the state of the speaker upon the basis of phonetic data and then discuss several possible explanations of the pattern of change found in the recordings of Captain Hazelwood.

    This study presents the fatal case of a young man who was admitted to the ICAU due to sudden cardiac arrest. An interview revealed that the patient had taken some unspecified crystals. From the moment of admission, his condition deteriorated dramatically as a result of increasing circulatory insufficiency. After a few hours, sudden cardiac arrest occurred again and the patient was pronounced dead. In the course of a medicolegal autopsy, samples of biological material were preserved for toxicology tests and histopathological examination. The analysis of samples using the LC-MS/MS technique revealed the presence of α-PVP in the following concentrations: blood-174 ng/mL, urine-401 ng/mL, brain-292 ng/g, liver-190 ng/g, kidney-122 ng/g, gastric contents-606 ng/g. The study also presents findings from the parallel histopathological examination. Based on these findings, cardiac arrest secondary to intoxication with alpha-PVP was determined as the direct cause of the patient's death.

    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.

    Conflicting evidence suggests that bone lead or blood lead may reduce areal bone mineral density (BMD). Little is known about how lead at either compartment affects bone structure. This study examined postmenopausal women (N=38, mean age 76 ± 8, body mass index (BMI): 26.74 ± 4.26 kg/m(2)) within the Hamilton cohort of the Canadian Multicentre Osteoporosis Study (CaMos), measuring bone lead at 66% of the non-dominant leg and at the calcaneus using (109)Cadmium X-ray fluorescence. Volumetric BMD and structural parameters were obtained from peripheral quantitative computed tomography images (200 μm in-plane resolution, 2.3 ± 0.5mm slice thickness) of the same 66% site and of the distal 4% site of the tibia length. Blood lead was measured using atomic absorption spectrometry and blood-to-bone lead partition coefficients (PBB, log ratio) were computed. Multivariable linear regression examined each of bone lead at the 66% tibia, calcaneus, blood lead and PBB as related to each of volumetric BMD and structural parameters, adjusting for age and BMI, diabetes or antiresorptive therapy. Regression coefficients were reported along with 95% confidence intervals. Higher amounts of bone lead at the tibia were associated with thinner distal tibia cortices (-0.972 (-1.882, -0.061) per 100 μg Pb/g of bone mineral) and integral volumetric BMD (-3.05 (-6.05, -0.05) per μg Pb/g of bone mineral). A higher PBB was associated with larger trabecular separation (0.115 (0.053, 0.178)), lower trabecular volumetric BMD (-26.83 (-50.37, -3.29)) and trabecular number (-0.08 (-0.14, -0.02)), per 100 μg Pb/g of bone mineral after adjusting for age and BMI, and remained significant while accounting for diabetes or use of antiresorptives. Total lead exposure activities related to bone lead at the calcaneus (8.29 (0.11, 16.48)) and remained significant after age and antiresorptives-adjustment. Lead accumulated in bone can have a mild insult on bone structure; but greater partitioning of lead

    Botulinum neurotoxins (BoNTs) comprise seven distinct serotypes that inhibit the release of neurotransmitter across neuromuscular junctions, resulting in potentially fatal flaccid paralysis. BoNT serotype A (BoNT/A), which targets synaptosomal-associated protein of 25kDa (SNAP-25), is particularly long-lived within neurons and requires a longer time for recovery of neuromuscular function. There are currently no treatments available to counteract BoNT/A after it has entered the neuronal cytosol. In this study, we examined the ability of small molecule non-peptidic inhibitors (SMNPIs) to prevent SNAP-25 cleavage post-intoxication of neurons. The progressive cleavage of SNAP-25 observed over 5 h following 1 h BoNT/A intoxication was prevented by addition of SMNPIs. In contrast, anti-BoNT/A neutralizing antibodies that strongly inhibited SNAP-25 cleavage when added during intoxication were completely ineffective when added post-intoxication. Although Bafilomycin A1, which blocks entry of BoNT/A into the cytosol by preventing endosomal acidification, inhibited SNAP-25 cleavage post-intoxication, the degree of inhibition was significantly reduced versus addition both during and after intoxication. Post-intoxication application of SMNPIs, on the other hand, was nearly as effective as application both during and after intoxication. Taken together, the results indicate that competitive SMNPIs of BoNT/A light chain can be effective within neurons post-intoxication.

    Abstract Organophosphate (OP) poisoning is a critical cause of morbidity and mortality worldwide. We conducted a nationwide longitudinal cohort study to investigate the development of deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE) among patients admitted with OP intoxication. We identified patients with OP intoxication by using the Taiwan National Health Insurance Research Database and enrolled 9223 patients who were hospitalized for OP intoxication between 2000 and 2011. OP intoxication was diagnosed based on a clinical assessment and serum acetylcholinesterase levels at the time of hospital admission. Each patient in the OP intoxication cohort was randomly frequency matched with 4 patients without OP intoxication based on their age, sex, and index year (36,892 patients as control cohort), and all patients were observed from the index date until the appearance of a DVT or a PTE event, or until December 31, 2011. We analyzed the risks of DVT and PTE by using Cox proportional hazards regression models that included the demographic variables of sex, age, and comorbidities (eg, hypertension, diabetes, cerebral vascular disease, heart failure, all cancer types, and lower leg fracture or surgery). The results revealed a significantly increased risk of developing DVT among patients with OP poisoning (adjusted hazard ratio [HR] = 1.55; 95% confidence interval [CI] = 1.03–2.34) but not PTE (adjusted HR = 1.44; 95% CI = 0.83–2.52). Among the patients without comorbidities, the OP poisoning patients compared with controls had a higher adjusted HR of 2.12 (95% CI = 1.21–3.71) for DVT. The results of this nationwide cohort study indicate that the risk of developing DVT is markedly higher in patients with OP intoxication compared with that of the general population. PMID:25569651

    Pickles are popular in China and exhibits health-promoting effects. However, nitrite produced during fermentation adversely affects health due to formation of methemoglobin and conversion to carcinogenic nitrosamine. Fruiting bodies of the mushroom Boletus edulis were capable of inhibiting nitrite production during pickle fermentation. A 90-kDa nitrite reductase (NiR), demonstrating peptide sequence homology to fungal nitrite reductase, was isolated from B. edulis fruiting bodies. The optimum temperature and pH of the enzyme was 45 °C and 6.8, respectively. B. edulis NiR was capable of prolonging the lifespan of nitrite-intoxicated mice, indicating that it had the action of an antidote. The enzyme could also eliminate nitrite from blood after intragastric administration of sodium nitrite, and after packaging into capsule, this nitrite-eliminating activity could persist for at least 120 minutes thus avoiding immediate gastric degradation. B. edulis NiR represents the first nitrite reductase purified from mushrooms and may facilitate subsequent applications. PMID:26446494

    Abstract Evaluation of acute white matter injuries caused by carbon monoxide (CO) poisoning can be limited by conventional magnetic resonance (MR) imaging. We aim to evaluate the feasibility of diffusion kurtosis imaging (DKI) for early detection of white matter alterations in patients with acute CO intoxication. A total of 30 subjects including 15 acute CO patients and 15 age- and sex-matched healthy volunteers were enrolled in this study. MR examinations were performed on a 3T MR scanner within 8 days after CO intoxication. DKI data were acquired to derive axial, radial, and mean kurtosis, as well as fractional anisotropy (FA), axial, radial, and mean diffusivity for tract-specific comparisons between the 2 groups. Significant decreases of mean kurtosis were shown in the genu of corpus callosum, cingulum, and motor-related tracts (corticospinal and corticobulbar tracts) in patients with acute CO intoxication as compared with controls. On the contrary, significant differences of FA values were merely shown in the regions of corticospinal tracts. DKI demonstrated comparably stronger potential than diffusion tensor imaging in terms of early detection of white matter changes in patients with acute CO intoxication. This may have implications in therapeutic strategy for managing acute CO intoxication patients. PMID:28151889

    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.

    A variety of health effects have been attributed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), but little information is available on the course of a verified high-level TCDD intoxication. In this paper we describe two cases of heavy intoxication with TCDD and present a 2-year follow-up including clinical, biochemical, hematologic, endocrine, and immunologic parameters monitored in two women, 30 and 27 years of age, who suffered from chloracne due to TCDD intoxication of unknown origin. Patient 1, who had the highest TCDD level ever recorded in an individual (144,000 pg/g blood fat), developed severe generalized chloracne, whereas in the second patient, despite heavy intoxication (26,000 pg/g blood fat), only mild facial acne lesions occurred. Both patients initially experienced nonspecific gastrointestinal symptoms. In Patient 1 we observed a moderate elevation of blood lipids, leukocytosis, anemia, and secondary amenorrhoea. The laboratory parameters in Patient 2 were all normal. Despite the high TCDD levels, apart from chloracne, only few clinical and biochemical health effects were observed within the first 2 years after TCDD intoxication. PMID:11564625

    An experiment tested the pathways through which alcohol expectancies and intoxication influenced men's self-reported sexual aggression intentions during an unprotected sexual encounter. After a questionnaire session, male social drinkers (N = 124) were randomly assigned to either an alcohol condition (target peak BAC = .08%) or a control condition. Upon completion of beverage consumption, participants read a description of a sexual encounter in which the female partner refused to have unprotected sexual intercourse. Participants then rated their emotional state, their intentions to have unprotected sex with the unwilling partner, and their postincident perceptions of the encounter. Structural equation modeling indicated that intoxicated men reported feeling stronger sexual aggression congruent emotions/motivations such as arousal and anger; however, this effect was moderated by alcohol expectancies. Intoxicated participants with stronger alcohol-aggression expectancies reported greater sexual aggression congruent emotions/motivations than did intoxicated participants with weaker alcohol-aggression expectancies. For sober participants, alcohol-aggression expectancies did not influence emotions/motivations. In turn, stronger sexual assault congruent emotions/motivations predicted greater sexual aggression intentions. Men with greater sexual aggression intentions were less likely to label the situation as a sexual assault and reported less concern about their intended actions. These findings underscore the relevance of both alcohol expectancies and alcohol intoxication to sexual aggression perpetration and highlight the importance of including information about alcohol's influence on both emotional and cognitive responses in sexual aggression prevention work.

    This quasi-experimental field study assessed whether an incentive/reward intervention can change the drinking behavior and the subsequent levels of intoxication among college students attending fraternity parties. A total of 356 blood alcohol concentration (BAC) assessments, using hand-held breathalyzers. were obtained at two baseline and at two intervention parties at the same fratenity house. At the intervention parties, the students were informed they could win a cash prize if their BAC was below .05, and they were given nomograms to aid in monitoring their levels of intoxication. Mean BAC and the percentage of partiers with intoxication levels above .05 were significantly lower at the two intervention parties. More than twice as many partygoers were legally intoxicated (i.e., BAC > .08) at the two baseline parties than at the two intervention parties. indicating a clinically significant impact of the incentive/reward intervention. Greek-life students, in particular, were significantly less intoxicated at intervention parties, compared to baseline parties (p < .001).

    Caffeine is arguably the most widely used stimulant drug in the world. Here we describe a suicide attempt involving caffeine overdose whereby the patient's severe intoxication was successfully treated with the prompt infusion of Intralipid. A 19-year-old man was found in an agitated state at home by the volunteer emergency team about 1 h after the intentional ingestion of 40 g of caffeine (tablets). His consciousness decreased rapidly, followed quickly by seizures, and electrocardiographic monitoring showed ventricular fibrillation. Advanced life support maneuvers were started immediately, with the patient defibrillated 10 times and administered 5 mg epinephrine in total and 300 + 150 mg of amiodarone (as well as lidocaine and magnesium sulfate). The cardiac rhythm eventually evolved to asystole, necessitating the intravenous injection of epinephrine to achieve the return of spontaneous circulation. However, critical hemodynamic instability persisted, with the patient's cardiac rhythm alternating between refractory irregular narrow complex tachycardia and wide complex tachycardia associated with hypotension. In an attempt to restore stability we administered three successive doses of Intralipid (120 + 250 + 100 mg), which successfully prevented a severe cardiovascular collapse due to a supra-lethal plasma caffeine level (>120 mg/L after lipid emulsion). The patient survived without any neurologic complications and was transferred to a psychiatric ward a few days later. The case emphasizes the efficacy of intravenous lipid emulsion in the resuscitation of patients from non-local anesthetic systemic toxicity. Intralipid appears to act initially as a vehicle that carries the stimulant drug away from heart and brain to less well-perfused organs (scavenging mechanism) and then, with a sufficient drop in the caffeine concentration, possibly as a tonic to the depressed heart.

    Colchicine, an old and well-known drug, is an alkaloid extracted from Colchicum autumnale and related species. 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 and the decision to start hemodialysis must be made promptly for patients who develop lactic acidosis. PMID:24353429

    Methoxetamine (MXE) is increasingly used and abused, as it is frequently presented as being safer than ketamine, and legal. Cases of only MXE consumption being associated with the occurrence of seizures are rarely reported. A single MXE intoxication case by inhalation is described concerning a 21-year-old man, not known to be epileptic, who was found collapsed in his bedroom, supposedly after an epileptic seizure. He was transferred to the Emergency Department of the Henri Mondor Hospital, Aurillac, France. He was conscious, but with a sinus bradycardia (48/min) and an ST-segment elevation on the electrocardiogram, and a slightly increased creatine kinase level (270 U/L) and hyponatremia (127 mmol/L). New seizure activity occurred during hospitalization, but the clinical course in the intensive care unit was favorable. Quantitation of MXE in serum and urine using gas chromatography coupled to mass spectrometry (GC-MS) was developed, as well as a liquid chromatography coupled to tandem mass spectrometry (LC-MS-MS) method for the determination of MXE in hair. Limits of detection and quantification were, respectively, 2 and 10 µg/L for the GC-MS method and both 0.5 pg/mg for the LC-MS-MS method. Concentrations of 30 and 408 µg/L were, respectively, measured in serum and urine. Concentrations of 135 and 145 pg/mg were detected in two 2.5 cm hair strands, consistent with one or several consumptions during the 2 ½ months prior to sampling. A sample of the powder consumed was available and also analyzed. This case illustrates the dangers of this drug, which justify its classification as a narcotic in France since August 2013.

    Mixed antihypertensive drug intoxication poses a significant risk for patient mortality. In tandem to antihypertensives, hypolipidemic medicines (especially statins) are often prescribed. Among their well-known adverse effects belongs rhabdomyolysis. We report a case of fatal multi-drug overdose in a 65-year-old female alcoholic. The patient was unconscious at admission. Empty blister packs indicated the abuse of 250 tablets of urapidil, 42 tablets of verapamil/trandolapril, 50 tablets of moxonidin, 80 tablets of atorvastatin and 80 tablets of diacerein. Standard measures (gastric lavage, activated charcoal, mechanical ventilation, massive doses of vasopressors, volume expansion, diuretics and alkalinization) failed to provide sufficient drug elimination and hemodynamic support and the sufferer deceased on the fourth day. Dramatic elevations of serum myoglobin (34,020 μg/L) and creatine kinase (219 μkat/L) were accompanied by rise in cardiac troponin I and creatinine. Gas chromatography revealed ethanol 1.17 g/kg (blood) and 2.81 g/kg (urine). Thin layer chromatography and gas chromatography of gastric content and urine verified verapamil, moxonidin and urapidil fragment (diacerein method was unavailable). Atorvastatin and trandolapril concentrations (LC-MS(n)) equaled 277.7 μg/L and 57.5 μg/L, resp. (serum) and 8.15 μg/L and 602.3 μg/L, resp. (urine). Histology confirmed precipitates of myoglobin with acute necrosis of proximal renal tubules in association with striated muscle rhabdomyolysis and myocardial dystrophy. Cardiogenic-distributive shock in conjunction with acute renal failure due to the combined self-poisoning with vasoactive agents and atorvastatin were determined to be this decedent's immediate cause of death. The manner of death was assigned to be suicidal.

MC simulation of phantom seed arrangements show that dose at a point can be reduced by up to 18% and this has been validated using a MOSFET dosimeter. Clinical simulations show that ISA reduces DVH parameter values, but the reduction is less for thinner seeds.

    This study tested within-person associations between intoxication, negative affect, and self-control demands and two forms of self-control failure, interpersonal conflict, and neglecting responsibilities. Effortful control was hypothesised to act as a buffer, reducing individual susceptibility to these within-person effects. In contrast, reactivity was hypothesised to potentiate the within-person associations. 274 young adults aged 18–27 (56% women, 93% white) completed experience sampling assessments for up to 49 days over the course of 1.3 years. Results indicated independent within-person effects of intoxication, negative affect, and self-control demands on the outcomes. Hypothesised moderating effects of reactivity were not supported. Effortful control did not moderate the effects of self-control demands as expected. However, effortful control exhibited a protective effect when individuals were intoxicated or upset to reduce the likelihood of maladaptive behavioural outcomes. PMID:26264715

    In this study, the perceptions of victim intoxication and the drinking context (i.e., who purchased the drinks) were investigated. Men and women mock jurors (N = 158) read a rape trial summary in which the victim was intoxicated or sober, and either the victim or the perpetrator purchased the drinks. Overall, participants who perceived a victim as intoxicated were less likely to render guilty verdicts and made lower ratings of victim credibility. In addition, when the perpetrator purchased the drinks, participants were more likely to render guilty verdicts and made more negative judgments about the defendant than when the victim bought the drinks. Mediation analyses explained the relationship between the independent variables and verdict. The results are discussed in terms of the factors that influence juror perceptions of rape cases in court.

    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. PMID:16608508

    Water intoxication in schizophrenia poses a great clinical challenge, and occasionally, behavioral restrictions are unavoidable. A patient with refractory schizophrenia comorbid with severe water intoxication had an apparent weight variation of ,7 kg/day to 65 kg. As he fell twice, when he had been treated with antipsychotic megadose therapy, he was secluded with restricted water access of 3 L/day. Two days later, consciousness level deteriorated significantly with autonomic instability; however, he was treated with intravenous hydration plus dantrolene and recovered completely on the following day. The sodium/chloride levels and serum osmolarity, which had been abnormally low, normalized abruptly. Only after seclusion was it found that his dry weight had been only 52 kg. The first description of such a case was indicative of a potentially aborted neuroleptic malignant syndrome. He is now treated with olanzapine, valproate, and lorazepam, with some success. Caution is required for secluding extreme cases of uncontrollable water intoxication.

    To assess the effects of chronic cocaine intoxication on dopamine receptors in human subjects, the authors evaluated ({sup 18}F)N-methylspiroperidol binding using positron emission tomography in 10 cocaine abusers and 10 normal control subjects. Cocaine abusers who had been detoxified for 1 week or less showed significantly lower values for uptake of ({sup 18}F)N-methylspiroperidol in striatum than the normal subjects, whereas the cocaine abusers who had been detoxified for 1 month showed values comparable to those obtained from normal subjects. The authors conclude that postsynaptic dopamine receptor availability decreases with chronic cocaine abuse but may recover after a drug-free interval.

  8. Intoxication and settled insanity: a finding of not guilty by reason of insanity.

    2007-01-01

    This article presents a case of first-degree murder for which the defendant was acquitted as not guilty by reason of insanity, based on a defense involving the concept of "settled insanity." The literature on settled insanity is reviewed and discussed in the context of voluntary and involuntary intoxication. Statute and case law from those jurisdictions in which settled insanity is specifically allowed as an acceptable threshold condition for the insanity defense define the concept as a permanent condition resulting from substance abuse, rather than the effects of intoxication, no matter how severe. Also discussed are potential criteria for this defense, including evidence that psychotic symptoms thought to be responsible for the crime were, in some manner, separate and apart from symptoms caused solely by voluntary acute intoxication. Other factors that may assist evaluators in differentiating settled insanity from the effects of acute intoxication are presented. It is recommended that evaluators attempt to determine the timing of the onset of psychotic symptoms in relation to substance abuse, the persistence of such symptoms beyond detoxification, and whether ongoing psychiatric treatment is necessary to ameliorate the symptoms beyond intoxication. In the case described, psychotic symptoms persisted long after acute intoxication and beyond the time when drugs or alcohol were detected in the accused's body, requiring clinical intervention for psychosis. Also, before the crime, the defendant had exhibited significant psychological difficulty. The evaluating clinician must still determine, even when a threshold condition is considered to be present, whether statutory criteria for the insanity defense (for the jurisdiction in which the crime allegedly took place) are met.

    The objective was to assess the effect of early onset intoxication on subsequent alcohol involvement among urban American Indian youth. The data come from the American Indian Research (AIR) project, a panel study of urban Indian youth residing in King County, Washington. Data were collected annually from the adolescent and his/her primary caregiver from the 1988-89 school year to the 1996-97 school year, providing a total of nine waves of data. Early intoxication (by age 14) was related to delinquency, family history of alcohol abuse or dependence, poverty, broken family structure, less family cohesiveness, and more family conflict. The effects of these characteristics were, therefore, partialed out in testing effects of early intoxication on later alcohol involvement. Two-part latent growth models of alcohol use and alcohol problems were specified. Effects of early onset intoxication on these trajectories, as well as lifetime alcohol abuse or dependence by the transition to young adulthood, were examined. Findings indicate that adolescents who experienced their first intoxication early (by age 14), used alcohol more heavily from the ages of 16 to 18, experienced more problems related to the alcohol's use from the ages of 16 to 18, and were more likely to have a diagnosed alcohol disorder by the final wave of data collection. Congruent with similar studies in the general population, early intoxication appears to be associated with a deleterious course of alcohol involvement during adolescence and into the transition to young adulthood among urban American Indian youth. Implications for prevention are discussed.

    Carbon monoxide (CO) intoxication could cause significant cardiac injury. Although cardiac dysfunction after CO intoxication can be presented, the echocardiographic findings after CO intoxication are poorly defined. The purpose of this study was to evaluate the clinical patterns of left ventricular (LV) systolic dysfunction using echocardiography. A total of 132 CO-intoxicated patients were enrolled. Clinical, demographic and laboratory data and echocardiographic findings were analyzed. The LV dysfunction group (29 patients) showed higher lactate level (5.8 ± 3.3 vs. 4.1 ± 3.5 mmol/L, p = 0.024) and lower base excess (BE) (-8.2 ± 6.0 vs. -4.8 ± 4.7 mEq/L, p = 0.001) compared with normal LV function group. Among the LV dysfunction group, three different echocardiographic patterns were presented. Regional wall motion abnormality was presented in 14 patients. Apical ballooning, typical finding of stress-induced cardiomyopathy, was presented in eight patients. Global hypokinesia of LV was presented in seven patients. Laboratory findings indicating the severity of CO intoxication, such as lactate level, pH value, BE and aspartate aminotransferase, showed statistical significance according to the patterns of LV dysfunction (p = 0.033, 0.022, 0.02 and 0.006, respectively). Our results demonstrate that CO intoxication could induce various patterns of LV dysfunction. The patterns of LV dysfunction might affect subsequent clinical outcomes.

  11. Acute Alcohol Intoxication Decreases Glucose Metabolism but Increases Acetate Uptake in the Human Brain

    Alcohol intoxication results in marked reductions in brain glucose metabolism, which we hypothesized reflect not just its GABAergic enhancing effects but also metabolism of acetate as an alternative brain energy source. To test this hypothesis we separately assessed the effects of alcohol intoxication on brain glucose and acetate metabolism using Positron Emission Tomography (PET). We found that alcohol intoxication significantly decreased whole brain glucose metabolism (measured with FDG) with the largest decrements in cerebellum and occipital cortex and the smallest in thalamus. In contrast, alcohol intoxication caused a significant increase in [1-11C]acetate brain uptake (measured as standard uptake value, SUV), with the largest increases occurring in cerebellum and the smallest in thalamus. In heavy alcohol drinkers [1-11C]acetate brain uptake during alcohol challenge trended to be higher than in occasional drinkers (p <0.06) and the increases in [1-11C]acetate uptake in cerebellum with alcohol were positively associated with the reported amount of alcohol consumed (r=0.66, p<0.01). Our findings corroborate a reduction of brain glucose metabolism during intoxication and document an increase in brain acetate uptake. The opposite changes observed between regional brain metabolic decrements and regional increases in [1-11C]acetate uptake support the hypothesis that during alcohol intoxication the brain may rely on acetate as an alternative brain energy source and provides preliminary evidence that heavy alcohol exposures may facilitate the use of acetate as an energy substrate. These findings raise the question of the potential therapeutic benefits that increasing plasma acetate concentration (ie ketogenic diets) may have in alcoholics undergoing alcohol detoxification.

    Verapamil intoxication is a life-threatening condition that often presents with severe hemodynamic instability and requires vasopressor support. There are also documented case reports of the development of non-cardiogenic pulmonary oedema after verapamil overdose. However, the exact mechanisms responsible for pulmonary oedema remain unclear. Here, we describe a 36-year-old woman who was admitted to the intensive care unit after ingesting high-dose verapamil and subsequently developed acute respiratory distress syndrome soon after hemodynamic stabilization. Possible mechanisms are presented after taking into account findings in the current literature. Acute respiratory distress syndrome should be considered early during the evaluation of patients with verapamil intoxication.

    Simultaneous kidney pancreas transplantation (SKP) is a common procedure for the patient with long-term type 1 diabetes mellitus (DM) with terminal renal failure. It is unusual to consider the pancreas from a deceased donor who died after an acute intoxication with oral antidiabetic agent (OAA), which would suggest an abnormal functionality of the organ and preclude the potential use of the graft. We present a case of a successful pancreatic transplantation from a donor who died of acute cerebral edema secondary to severe hypoglycemia induced by OAA acute intoxication.

    Using data from the Welfare, Children, and Families project (1999), a probability sample of 2,280 low-income women with children living in low-income neighborhoods in Boston, Chicago, and San Antonio, we examine the effects of relationship violence before age 18 and in the past year on frequency of adult intoxication. Results obtained from a series of ordered logistic regression models suggest that sexual coercion before age 18 and minor and severe physical assault in the past year are independently associated with greater frequency of intoxication, net of a range of sociodemographic controls. The study's limitations are noted.

    The experiment on 83 rats has provided a rationale for the use of enterosorbents in acute ethanol intoxication. Polysorb reduces the halflife of ethanol, recovers physical fitness in the animals with acute poisoning. The enterosorbents polysorb, litovit, and sapropel have been found to have a corrective effect on the level of the major plasma antioxidant ceruloplasmin in acute ethanol intoxication. Enterosorbents are an effective detoxifying agent in this condition. Examining the mechanisms of toxic action of ethanol allows the most expedient treatment policy to be substantiated in acute poisonings.

    In the emergency medicine field cases of intoxication by sniffing agents do not occur very often. Nevertheless, considering the easy availability of butane the option of abuse especially by adolescent persons cannot be ignored. Although many cases of accidental death caused by malignant arrhythmia are described ("Sudden sniffing death syndrome"), suicide attempts using butane are a rarity. In this case the emergency treatment has to allow for special pathophysiological changes explained by physicochemical characteristics of butane. The following case report describes the symptomatology and pre-hospital treatment of an intoxication by butane with a suicidal intention.

    Patients rarely consult physicians before developing coagulopathy or bleeding in most reported cases of superwarfarin intoxication. A 57-year-old woman ingested red-dyed pellets of anticoagulant rodenticide containing difethialone and warfarin as well as tablets of nitrazepam. Although she presented to the hospital in a comatose state, notable pink-colored excreta hinted at the consumption of anticoagulant rodenticide, which led to the early diagnosis of superwarfarin intoxication. Supplementation of large doses of intravenous and oral vitamin K successfully prevented coagulopathy and bleeding. On the other hand, temporary and reversible myocardial suppression was extremely severe, and required the introduction of percutaneous cardiopulmonary support.

    Intracranial pressure (ICP) monitoring has been used widely for patients with intracranial hypertension. However, the data of mean ICP do not reflect various brain conditions correctly. Therefore, we performed ICP -waveform analysis to assess brain compliance. Data for ICP -waveform analysis were obtained by stereotactic intraventricle puncture. ICP waveform is expressed as a three-phase wave. Analyzed differential waveforms in a water intoxication model and continuous infusion models were evaluated respectively. In the water intoxication models, the second wave (P2) known to reflect compliance is elevated. ICP waveform analysis will be valuable for the assessment of the pathological condition of the brain.

    Multiple organ dysfunction syndrome (MODS) has rarely been described in patients with heroin intoxication. Here, we report a rare case of MODS involving six organs, due to heroin intoxication. The patient was a 32-year-old Chinese man with severe heroin intoxication complicated by acute pulmonary edema and respiratory insufficiency, shock, myocardial damage and cardiac insufficiency, rhabdomyolysis and acute renal insufficiency, acute liver injury and hepatic insufficiency, toxic leukoencephalopathy, and hypoglycemia. He managed to survive and was discharged after 10 weeks of intensive care. The possible pathogenesis and therapeutic measures of MODS induced by heroin intoxication and some suggestions for preventing and treating severe complications of heroin intoxication, based on clinical evidence and the pertinent literature, are discussed in this report.

    Prevalence of electrolyte disturbances and biochemical changes were determined in patients admitted to the emergency room of the Department of Internal Medicine in Innsbruck, Austria during a six-month period. The value of biochemical parameters for the detection of chronic alcohol abuse was also investigated. The most frequent electrolyte disturbances found were hypernatremia (41%), hyperchloremia (21%), hypermagnesemia (17%) and hypocalcemia (15%), whereas hypokalemia and hypophosphatemia were observed quite rarely (5% and 3.4%, respectively). The most frequent biochemical changes observed were consistent with signs of cellular toxicity i.e. increased liver enzymes (elevated gamma-glutamyltransferase (GGT), aspartate aminotransferase, alanine aminotransferase and lactic dehydrogenase) as well as signs of pancreatitis (elevated serum lipase and amylase) and muscle damage (elevated creatine kinase). The most frequent changes in blood counts were leucocytosis (23%), thrombocytopenia (14%), and anemia (12%). C-reactive protein showed only minimal elevation. Male sex and level of blood alcohol were detected as major risk factors for the diagnosis of chronic alcohol abuse in the patient sample investigated. When testing the value of routinely measured parameters for predicting the presence of chronic alcohol abuse, GGT and mean corpuscular volume of red blood cells (MCV) appeared to be of equal value. A combination of elevated blood alcohol with an increase in either of these markers may be interpreted as high risk for chronic alcohol abuse in this particular group of patients.

    Parkinson's disease (PD) is characterized by progressive loss of dopamine (DA) neurons in the nigrostriatal system and by the presence of Lewy bodies (LB), proteinaceous inclusions mainly composed of filamentous α-synuclein (α-Syn) aggregates. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was adopted to generate PD models in C57BL/6 mice. In the present study, we investigated the effect of geraniol (GE) against α-Syn aggregation on MPTP induced mouse model of PD in dose dependant manner. When pretreatment of GE improved neuromuscular impairment, TH expressions and decreases α-Syn expressions in MPTP intoxicated PD mice by dose dependent manner. In addition, we confirmed that sub-chronic administration of MPTP in mice leads to permanent neuromuscular deficits and depletion of dopamine and its metabolites. Our results suggest that GE is beneficial for the treatment of PD associated with neuromuscular disability and LB aggregation.

    Aluminum absorption leads to deposits in several tissues. In this study, we have investigated, to our knowledge for the first time, aluminum deposition in the salivary glands in addition to the resultant cellular changes in the parotid and submandibular salivary glands in a model of chronic intoxication with aluminum citrate in rats. Aluminum deposits were observed in the parotid and submandibular glands. Immunohistochemical evaluation of cytokeratin-18 revealed a decreased expression in the parotid gland with no changes in the submandibular gland. A decreased expression of α-smooth muscle actin was observed in the myoepithelial cells of both glands. The expression of metallothionein I and II (MT-I/II), a group of metal-binding proteins, which are useful indicators for detecting physiological responses to metal exposure, was higher in both glands. In conclusion, we have shown that at a certain time and quantity of dosage, aluminum citrate promotes aluminum deposition in the parotid and submandibular glands, leads to an increased expression of MT-I/II in both the glands, damages the cytoskeleton of the myoepithelial cells in both glands, and damages the cytoskeleton of the acinar/ductal cells of the parotid glands, with the submandibular glands showing resistance to the toxicity of the latter.

    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.

  5. Antihypertensive therapy in patients on chronic lithium treatment for bipolar disorders.

    2016-01-01

    Bipolar disorders are chronic conditions treated with lithium, which exerts deleterious effects on the kidney, among which nephrogenic diabetes insipidus, tubular acidosis and ultimately chronic kidney disease. Conversely, drugs that alter renal function can modify its serum levels and lead to the potentially fatal lithium intoxication. A search in the main library databases from 1975 to 2015 to identify interactions between antihypertensive drugs and lithium using the Population Intervention Comparison Outcome strategy provided only 30 reports of lithium intoxication. A regression analysis showed that the severity of lithium intoxication was significantly predicted by female, age, and use of certain classes of antihypertensive agents. A model including certain albeit not all diuretics and/or inhibitors of the renin-angiotensin system, but not age, serum lithium or creatinine levels at baseline and/or on admission to the hospital, predicted lithium toxicity. The true incidence of lithium intoxication is unknown but probably low, albeit underestimated. Nonetheless, in patients treated with lithium, monitoring of the serum lithium levels and clinical conditions is mandatory after the introduction of antihypertensive drugs, as diuretics and renin-aldosterone system inhibitors.

    Aflatoxins are mycotoxins that have important toxic effects on human and animal health, even if consumed at low doses. The oral administration of piperine (1.12 mg/kg) during 23 days in rats seemingly interfered with the toxicity of aflatoxins, decreasing hepatic injuries and the leukocyte depletion in experimentally intoxicated animals.

    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.

    BACKGROUND: Aluminium phosphide (AlP) is used as a fumigant. It produces phosphine gas which is a mitochondrial poison. Although this poisoning has been repeatedly reported in literature with a high mortality rate, there is no known antidote for AlP intoxication. In the present study, we studied the effects of hyperbaric oxygenation (HBO) on the survival time of AlP intoxicated rats. METHODS: Intoxicated rats with AlP (11.5 mg/kg, oral gavage) were placed in hyperbaric oxygenation with different concentrations of compressed air and oxygen. RESULTS: All the animals exposed to AlP died within 5 days. The mean survival times of rats exposed to AlP without any intervention, treated with hyperbaric condition by compressed air, and treated with hyperbaric condition by pure O2 were 91 ± 1, 262 ± 8, and 276 ± 6 minutes, respectively. In analysis of survival times, there was a significant difference between Group 2 which received AlP and the groups which underwent intervention (Groups 2 and 3, p < 0.001; Groups 2 and 4, p < 0.001). CONCLUSIONS: Hyperbaric oxygenation may probably improve the survival time of the intoxicated rats with aluminium phosphide, but it may not decrease the mortality rate. PMID:22973324

    This study investigates the comparative hepatoprotective activity of crude ethanol extracts of Cuscuta australis against acetaminophen (APAP) intoxication. Thirty-six rats were randomly divided into six groups of 6 replicates: Group 1 which served as control received water. Group 2 was orally administered 835 mg/kg body wt. of paracetamol on day 8. Groups 3 and 4 were orally administered ethanolic extracts of the seed of Cuscuta australis in doses of 125 mg/kg and 250 mg/kg, respectively, for 7 days and then intoxicated as in Group 2 on the 8th day. Groups 5 and 6 received similar oral doses of Cuscuta australis stem extracts for 7 days and then intoxicated as in Groups 3 and 4. Group 2 rats showed severe periportal hepatic necrosis, significantly elevated serum hepatic injury markers, markedly increased lipid peroxidation, and decreased hepatic antioxidant enzymes activities. Remarkably, Cuscuta australis (seed and stem) extract pretreatments in Groups 3, 4, 5, and 6, most especially, the stem extract pretreatment in Groups 5 and 6, improved better the hepatic histoarchitecture, the hepatocellular, and the oxidative stress injury markers in a dose-dependent manner. Conclusively, ethanol extractions of Cuscuta australis stem appear to protect the liver from acetaminophen intoxication better than the seed counterpart. PMID:27433518

    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.

    2009-06-01

    High rates of binge drinking and alcohol-related problems, including drinking and driving, occur among college students. Underlying reasons for the heightened impaired driving rates in this demographic group are not known. The authors hypothesized that acute tolerance to the interoceptive cues of intoxication may contribute to these maladaptive decisions to drive in binge drinkers. Groups of binge-drinking and non-binge-drinking college students (N = 28) attended sessions during which they received a moderate dose of alcohol (0.65 g/kg) or a placebo. The development of acute tolerance to subjective ratings of intoxication and simulated driving performance was assessed by comparing measures taken during the ascending phase and descending phases of the blood alcohol curve. Compared with placebo, alcohol increased ratings of intoxication and impaired multiple aspects of simulated driving performance in both binge and non-binge drinkers. During the descending phase of the blood alcohol curve, binge drinkers showed acute tolerance to alcohol's effect on subjective intoxication, and this effect was accompanied by an increased rating of willingness to drive. By contrast, non-binge drinkers showed no acute tolerance.

    There is no specific antidote for intoxication with synthetic cannabinoids. In this case series, we considered the efficiency of intravenous lipid emulsion therapy in four cases, who presented to emergency department with synthetic cannabinoid (bonzai) intoxication. The first patient had a GCS of 3 and a left bundle branch block on electrocardiography. The electrocardiography revealed sinus rhythm with normal QRS width after the treatment. The second patient had bradycardia, hypotension, and a GCS of 14. After intravenous lipid emulsion therapy, the bradycardia resolved, and the patient's GCS improved to 15. The third patient presented with a GCS of 8, and had hypotension and bradycardia. After the treatment, not only did the bradycardia resolve, but also the GCS improved to 15. The fourth patient, whose electrocardiography revealed accelerated junctional rhythm, had a GCS of 13. The patient's rhythm was sinus after the treatment. Cardiovascular recovery was seen in all four cases, and neurological recovery was also seen in three of them. Based on the fact that intravenous lipid emulsion is beneficial in patients intoxicated with lipophilic drugs, unstable patients presenting to the emergency department with acute synthetic cannabinoid intoxication may be candidates for intravenous lipid emulsion treatment.

    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.

Methods We examined 9 patients with CO intoxication using DTI, VBM and neuropsychologic tests at an average of 3 and 10 months after CO exposure. We used data from 18 age- and sex-matched controls for comparison. Results We found that cognitive recovery at 10 months after CO intoxication was not significant, although it was after 3 months. The neuropsychologic tests correlated better for the fibre tract of the semicentrum ovale and not the periventricular fibres. Diffusion measures suggest increases in fractional anisotropy, mean diffusivity and axial eigenvalues over time, while increases in radial eigenvalue were evident at 3 months compared with controls. Periventricular white matter atrophy was observed 10 months after CO intoxication Limitations Our study included few cases, and the interpretation of the putative changes on neuroimaging findings cannot be confirmed by histology. Conclusion Our study showed that the evolution of white matter injury in CO encephalopathy occurred over time. Cognitive recovery was not evident in the follow-up period because of white matter injuries. PMID:20184809

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

    Alcohol abuse impairs the pulmonary immune response to infection and increases the morbidity and mortality of bacterial pneumonia. Acute alcohol intoxication suppresses lung expression of CXC chemokines bearing the Glu-Leu-Arg motif (ELR+) following lipopolysaccharide (LPS) challenge, but its effect on the structurally related ELR- CXC chemokines, which attract T cells, is unknown. We therefore investigated the effect of acute alcohol intoxication on the pulmonary response to intratracheal (i.t.) LPS challenge for the ELR- CXC chemokines monokine induced by gamma (MIG or CXCL9), interferon-inducible protein 10 (IP-10 or CXCL10), and interferon-inducible T cell alpha chemoattractant (I-TAC or CXCL11). Male C57BL/6 or C3H/HeN mice were given an intraperitoneal injection of ethanol (3.0 g/kg) or phosphate buffered saline 30 min before i.t. LPS challenge. Chemokine mRNA transcripts were measured at 0, 2, 6, and 16 h. Acute alcohol intoxication inhibited the lung's expression of all three chemokine genes in response to LPS. Lung IFN-gamma mRNA was also inhibited by acute intoxication over the same time course. The in vitro effect of ethanol on chemokine secretion was further studied in the MH-S alveolar macrophage cell line. IP-10, MIG, and I-TAC in response to LPS were enhanced by exogenous interferon (IFN)-gamma, and these responses were blunted by exposure to ethanol. Alcohol exposure did not affect MH-S cell nuclear factor kappa beta p65 nuclear localization during challenge, despite dose-dependent inhibition of Erk 1/2 phosphorylation. In addition, phospho-signal transduction and activator of transcription 1 was not decreased in the presence of acute ethanol, thereby indicating that acute intoxication does not affect IFN-gamma signaling in MH-S cells. Recruitment of CD3+ T cells into the alveolar space 4 days after LPS challenge was moderately impaired by acute ethanol intoxication. These results implicate acute ethanol intoxication as a significant inhibitor of

    The combination of intoxication and criminal responsibility has been a problem field for legal theory and practice for quite some time. While it has been argued in certain contexts that intoxication reduces or denies criminal responsibility, elsewhere it has been reasoned that intoxicated offenders should be held as (or even more so) legally responsible as sober ones. But even in legal systems where the criminal responsibility of intoxicated offenders is emphasized, legal theory and practice are confronted with the challenge of converting such values into workable jurisprudence, since many intoxicated offenders naturally lack one of the key premises for responsibility for a criminal act, namely mens rea. This article compares the very different legal philosophies and practices that have evolved around the issue of intoxication and criminal responsibility in Canada and Germany. While the Canadian system has long and in a variety of ways tried to reconcile the inherent tensions between the principles of legal culpability and the intent to punish intoxicated offenders in material law, the German system has produced a set of legal tools that allow for a pragmatic and ends-oriented approach. This article concludes that the evolution and profile of these legal schemes is likely linked to the cultural status of alcohol and drinking in the respective system context.

  2. Fatal alcohol intoxication in women: A forensic autopsy study from Slovakia

    2011-01-01

    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.

    Methamphetamine (MA) is an illicit psychostimulant, and its abuse has become an international public health problem. MA intoxication can cause life-threatening hyperthermia, renal and liver failure, cardiac arrhythmias, and neurological damage. To investigate the relationship between the underlying mechanism of such intoxication and metabolic networks, mass spectrometry-based metabolomics experiments were performed on Sprague-Dawley rats treated with MA at 10mgkg(-1)h(-1) for 4h. Using a combination of gas chromatography-time-of-flight mass spectrometry and capillary electrophoresis-tandem mass spectrometry, global and targeted analyses were performed on biological samples collected during 0-24 and 72-96h (for urine), and at 24 and 96h (for plasma) after the last drug administration. Body temperature and plasma biochemical parameters were also measured to detect abnormal reactions in neuronal and other several tissues. 5-Oxoproline, saccharic acid, uracil, 3-hydroxybutyrate (3-HB), adipic acid, glucose, glucose 6-phosphate, fructose 1,6-bisphosphate, and tricarboxylic acid (TCA) cycle intermediates, such as fumarate, were proposed as potential biomarkers related to MA-induced intoxications. In particular, the observation of decreased TCA cycle intermediates and 3-HB and increased glucose suggested that high doses of MA inhibit biogenic energy production by glycolysis, oxidative phosphorylation via the TCA cycle, and the beta-oxidation of fatty acids. These results may provide not only a clue to clarify the underlying mechanism of diverse intoxication effects, but also biological fluid-based diagnostic and forensic methods with which to objectively demonstrate intoxication without directly determining the drug.

    Previous research has demonstrated that adults with attention deficit/hyperactivity disorder (ADHD) are more likely to experience driving-related problems, which suggests that they may exhibit poorer driving performance. However, direct experimental evidence of this hypothesis is limited. The current study involved 2 experiments that evaluated driving performance in adults with ADHD in terms of the types of driving decrements typically associated with alcohol intoxication. Experiment 1 compared the simulated driving performance of 15 adults with ADHD to 23 adult control participants, who performed the task both while sober and intoxicated. Results showed that sober adults with ADHD exhibited decrements in driving performance compared to sober controls, and that the profile of impairment for the sober ADHD group did in fact resemble that of intoxicated drivers at the blood alcohol concentration level for legally impaired driving in the United States. Driving impairment of the intoxicated individuals was characterized by greater deviation of lane position, faster and more abrupt steering maneuvers, and increased speed variability. Experiment 2 was a dose-challenge study in which 8 adults with ADHD and 8 controls performed the driving simulation task under 3 doses of alcohol: 0.65g/kg, 0.45g/kg, and 0.0g/kg (placebo). Results showed that driving performance in both groups was impaired in response to alcohol, and that individuals with ADHD exhibited generally poorer driving performance than did controls across all dose conditions. Together the findings provide compelling evidence to suggest that the cognitive and behavioral deficits associated with ADHD might impair driving performance in such a manner as to resemble that of an alcohol intoxicated driver. Moreover, alcohol might impair the performance of drivers with ADHD in an additive fashion that could considerably compromise their driving skill even at blood alcohol concentrations below the legal limit.

    Mercury is an extremely dangerous environmental contaminant responsible for episodes of human intoxication throughout the world. Methylmercury, the most toxic compound of this metal, mainly targets the central nervous system, accumulating preferentially in cells of glial origin and causing oxidative stress. Despite studies demonstrating the current exposure of human populations, the consequences of mercury intoxication and concomitant use of drugs targeting the central nervous system (especially drugs used in long-term treatments, such as analgesics) are completely unknown. Morphine is a major option for pain management; its global consumption more than quadrupled in the last decade. Controversially, morphine has been proposed to function in oxidative stress independent of the activation of the opioid receptors. In this work, a therapeutic concentration of morphine partially protected the cellular viability of cells from a C6 glioma cell line exposed to methylmercury. Morphine treatment also reduced lipid peroxidation and totally prevented increases in nitrite levels in those cells. A mechanistic study revealed no alteration in sulfhydryl groups or direct scavenging at this opioid concentration. Interestingly, the opioid antagonist naloxone completely eliminated the protective effect of morphine against methylmercury intoxication, pointing to opioid receptors as the major contributor to this action. Taken together, the experiments in the current study provide the first demonstration that a therapeutic concentration of morphine is able to reduce methylmercury-induced oxidative damage and cell death by activating the opioid receptors. Thus, these receptors may be a promising pharmacological target for modulating the deleterious effects of mercury intoxication. Although additional studies are necessary, our results support the clinical safety of using this opioid in methylmercury-intoxicated patients, suggesting that normal analgesic doses could confer an additional

    Introduction Exposure to carbon monoxide (CO) is among the most common causes of acute and chronic poisonings worldwide. The crucial point of treatment of such acute poisonings is to eliminate CO from the body as fast as possible. There are currently two approaches to the management of the CO intoxication: hyperbaric oxygen therapy (HOT) and normobaric oxygen therapy (NOT). HOT is highly effective and capable of achieving the CO elimination half-time (T½) as low as 15 minutes. Unfortunately this method is expensive and not always readily available. The elimination of CO with the use of NOT (T½~70 min) is slower, but treatment can be started even on the site of the exposure and continued while the patient is transported to a hospital. The aim of the study was to evaluate the effectiveness of a method using therapeutic hyperventilation with maintenance of isocapnia (IH) in the elimination of CO in volunteers exposed to CO and to compare selected gasometric and respiratory parameters during IH with the values obtained during hyperventilation with pure oxygen (“non-isocapnic hyperventilation”–NIH). Material and methods The study involved 13 healthy, chronically-smoking volunteers. Each of them participated in two independent hyperventilation tests: IH and NIH. The levels of carboxyhemoglobin (COHb) and selected gasometric, cardiac and respiratory parameters were measured at 0, 10 and 20 minutes during both tests. Among 13 volunteers (8 women and 5 men) the initial COHb level was 5.0±1.5% (mean±SD) before the IH tests and 5.1±1.9% before the NIH tests (p>0.05). After 20 minutes of the procedures the mean COHb level was 2.9±0.9% for IH and 3.6±1.2% for NIH (p<0.01). The T½ of COHb was 29.6±12.2 min and 47.3±19.2 min respectively (p<0.01). After 10 minutes of NIH respiratory alkalosis was noted in 11 participants (84.6%). Such problem was not seen during the IH procedures. No serious adverse effects were recorded during either IH or NIH. Mild symptoms such

    Intravenous high-dose cyclophosphamide infusion, usually performed to treat malignant neoplasms, is known to cause water intoxication. Intravenous cyclophosphamide pulse therapy (IVCY) is increasingly being employed for the treatment of rheumatic diseases as well. Recently, water intoxication has been reported to occur even after low-to-moderate doses of IVCY. In the present paper, we describe a case of polyarteritis nodosa in a patient in whom water intoxication developed after IVCY at a moderate dose. Hydration is usually performed to maintain sufficient urine flow to avoid cystitis. Based on our case and a review of the literature, it is recommended that hydration should be carefully performed during IVCY in order to avoid water intoxication, especially when treating elderly patients.

    Datura stramonium is a wildly growing plant found in West Virginia and in temperate regions throughout the world that is sometimes abused by young people because of its hallucinogenic effects. D. Stramonium overdose produces a classic anticholinergic syndrome that can lead to severe and sometimes fatal complications. Poisoning can be confused with more commonly seen drugs of abuse, particularly synthetic drugs which are not revealed by standard drug screens. Misdiagnosis can delay appropriate care and potentially lead to poorer outcomes. We present a case of a 15 year-old male with acute D. Stramonium poisoning initially misdiagnosed with bath salt intoxication who required treatment by two emergency departments, a pediatric ICU, and who was ultimately transferred to an inpatient psychiatric facility. We then discuss differential diagnosis of D. Stramonium poisoning and bath salt intoxication and present management strategies for the two conditions.

    Organisms have sophisticated subcellular compartments containing enzymes that function in tandem. These confined compartments ensure effective chemical transformation and transport of molecules, and the elimination of toxic metabolic wastes. Creating functional enzyme complexes that are confined in a similar way remains challenging. Here we show that two or more enzymes with complementary functions can be assembled and encapsulated within a thin polymer shell to form enzyme nanocomplexes. These nanocomplexes exhibit improved catalytic efficiency and enhanced stability when compared with free enzymes. Furthermore, the co-localized enzymes display complementary functions, whereby toxic intermediates generated by one enzyme can be promptly eliminated by another enzyme. We show that nanocomplexes containing alcohol oxidase and catalase could reduce blood alcohol levels in intoxicated mice, offering an alternative antidote and prophylactic for alcohol intoxication.

    Acute poisoning is an important cause of morbidity and mortality during childhood. This manuscript reports the positive outcome of a pediatric case with a history of accidental carbamazepine intake treated using plasma exchange. A 3-year-old male presented with severe carbamazepine intoxication. He was comatose and had generalized tonic clonic seizure, ventricular tachycardia, and hypotension. Although he did not respond to classical therapies, we performed two sessions of plasma exchange. The patient recovered rapidly and was discharged from the hospital six days from the time of carbamazepine ingestion with no complication or neurologic impairment. Plasma exchange can be performed safely in very small children, and it might be the first line treatment, particularly for intoxication with drugs that have high plasma-protein-binding properties.

    Many homemade tamper processes of medical codeine formulations are available on selected "forums" on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called "cold water extraction." Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above-mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event.

    Male albino mice were intoxicated with a daily dose of 1 mg/kg of methylmercury chloride (MMC) for 7 days, and were treated thereafter with glutathione, N-acetyl-DL-homocysteine thiolactone, vitamin B complex, and vitamin E, either alone or in combinations for the next 7 days. The animals were sacrificed on the eighth day, with the exception of one group that was kept without toxic exposure for an additional 7 days and sacrificed on the fifteenth day. Brain, spinal cord, kidney, and liver of the animals were examined for changes in adenosine deaminase and 5{prime} nucleotidase. We found a severe inhibition of these enzymes during MMC intoxication and significant recovery during monothiols and vitamins administration, indicating the effectiveness of these agents in methylmercury detoxication. 26 refs., 2 figs.

    The first reports of methylmercury intoxication appeared in 1865 and 1866. These reports had sensational effects in European countries, and were introduced not only in journals but also in newspapers. These two reports were referable in Japan at the latest in 1927. The formation of organic mercury in the production of acetoaldehyde was also referable in 1906 in Japan. In 1931 (one year before the start of acetoaldehyde production in Minamata) these important reports cited above were referable in Kumamoto University, and there were warnings about the toxicity of organic mercury and environmental pollution prior to the start of acetoaldehyde production. However, not only the plant, authorities (Ministry of Welfare), and Kumamoto Prefectural Office, but also the scientists completely ignored these reports. Waste was dumped into the environment without any treatment. Serious pollution of the environment by organic mercury started, which resulted in the outbreak of Minamata disease (=methylmercury intoxication).

    A nearly two and a half year old boy was hospitalized after showing symptoms of disorientation and hallucination. The parents remembered the child playing with a bottle of Silomat cough drops, so that an intoxication was taken into consideration. After liquid/liquid extraction of a urine sample collected in hospital, the underivatized and the acetylated extracts were analyzed by gas chromatography-mass spectrometry (GC/MS) using electron ionization (EI) as well as chemical ionization (CI). In the urine sample high amounts of pentoxyverine (carbetapentane) and several of its metabolites, e.g., different hydrolyzed, desalkylated and ring-hydroxylated products have been identified. The correlation of the results, the observed symptoms, and the access to the Silomat cough drops reveal an intoxication after ingestion of an unknown amount of the antitussive pentoxyverine. Corresponding EI- and CI-GC/MS spectra are presented characterizing the structure of its metabolites.

    Diagnostic imaging is a valuable device in clinical management of poisoned patients presenting to emergency units in a comatose state. Some toxic agents have adverse effects on the central nervous system (CNS). Non-contrast computed tomography (CT) of the brain, as an available diagnostic method with a high resolution, can provide useful information about structural disturbances of unconscious patients with suspected drug or chemical intoxication. The authors would describe various presentations of toxic substances detected on the brain CT scans of ten patients with acute intoxication. While non-specific, CT findings of low-attenuation lesions in the basal ganglia, infarctions in young patients, or diffuse edema should raise suspicion for poisoning or overdose. PMID:21270943

    Water intoxication, a form of acute hyponatremia, has been described in various clinical situations. Although hyponatremia is a common metabolic disorder in hospitalized patients, it is generally not well known as a hazard in the labor and delivery room. However, several factors predispose laboring women to develop hyponatremia. Moreover, because the fetus acquires water from the maternal circulation via the placenta, and there is a close correlation between maternal and cord blood serum sodium levels, the newborn infant of a hyponatremic mother is also at considerable risk of developing water intoxication. We review the epidemiology, pathophysiology, clinical features, and treatment of this hazardous disorder. We emphasize the need for awareness of this condition, and call attention to the risk of fluid overload during labor.
