    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. PMID:16912033

    Lacquer thinner, commonly used for removing household paints is known to contain mixture of various arometic hydrocarbons; halogenated hydrocarbons and naptha, if ingested may rarely cause methemoglobinemia. We report a 3 year old child who presented to us with history of accidental ingestion of thinner, used for removing household paint. Child was having cyanosis with minimal tachypnoea & the colour of his blood was chocolate brown. Later methemoglibulin level estimations were also done, which were suggestive of this diagnosis. Child was managed conservatively with oxygen therapy & vital monitoring, which lead to complete recovery and discharge from hospital later. PMID:19347673

    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. PMID:27235798

    Classic symptoms of manganese intoxication are very rarely seen nowadays. Clinic in Angarsk Research Institute for Occupational medicine and Human ecology registered two cases of stage I and II chronic manganese intoxication over 10 years among electric welders. The cases were diagnosed with consideration of long length of exposure to manganese with the ambient air level exceeding the MAC 1.5 times, the disease manifestation at middle age, high manganese level in serum and urine, characteristic neurologic symptoms in association with organic psychopathologic defects and polyneuropathy of limbs.

    Although poisonings (fatal and non-fatal) due to intentional or accidental acute exposure to toluene or toluene mixture fumes have been previously reported in the literature, several issues concerning lethal doses or lasting post-exposure neuropathological impairments still remain unclear. Two male painters (18 and 30 years old) were accidentally exposed to toxic concentrations of paint diluent fumes containing toluene (TL), acetone (ACT) and methyl ethyl ketone (MEK) (60:15:15 w/w/w respectively) during their work in an underground reservoir. Both workers were found unresponsive by colleagues and were immediately transferred to the regional hospital. On admission, the younger man was pronounced dead, while the other remained in the intensive care unit for 3 days and then 4 days in the internal medicine ward. TL, ACT and MEK concentrations in blood samples taken from the survivor on admission were 6.3, 30.6 and 40.5 microg/mL. Postmortem toxicology of the dead worker revealed TL, ACT and MEK blood levels of 12.4, 90.8 and 80.4 microg/mL respectively. The solvent levels in the liver, kidney, lung, brain, testis and gland were also quantified and showed a somewhat similar distribution of the chemicals among these tissues with the highest levels found in the brain and the liver. The fatal and the non-fatal outcome that resulted despite similar intoxication conditions, most probably demonstrates the interindividual tolerance among the painters who also had similar body weights. The surviving painter did not develop any neuropsychological impairment in post-exposure time. The reported case strongly emphasizes the necessity to take precautions when using paint diluents in enclosed spaces. PMID:15335573

    Abuse of volatile inhalants has become a worldwide issue mainly among adolescents of low income social class. Acute and chronic exposure to these substances results in serious neurological and behavioral impairments. Although real exposure consists largely of simultaneous inhalation of multiple solvents, the vast majority of basic research studies have evaluated the actions of a single volatile component leaving the behavioral and neuronal effects of chemical mixture not fully understood. In this study, we investigated the acute behavioral effects of 300, 450 and 600 ppm of paint thinner inhalation on anxiety, locomotor activity and spatial memory. Additionally, the cognitive impairments related to chronic exposure of the same concentrations of thinner for 45 days were assessed. To understand the neuronal correlates of acute exposure to thinner, we used c-Fos immunohistochemistry as an endogenous marker of neuronal activation following 600 ppm of thinner. The results reveal that (i) chronically thinner exposed mice showed cognitive deficits in Morris water maze and object recognition tasks; (ii) acute inhalation of thinner induces a wide range of behavioral changes. These changes include an anxiolytic effect toward the aversive environmental bright light and a dose dependent effect on explorative locomotion. The wide range of behavioral alterations induced by acute thinner inhalation is consistent with the widespread distribution of thinner-induced c-Fos expression in multiple brain structures.

    To assess severity of cognitive disorders in chronic mercury intoxication, the authors performed claster and discrimination analysis of neuropsychologic and neurophysiologic research data from workers exposed to mercury during long length of service, from patients with early and marked stages of chronic mercurial intoxication. Cognitive disorders in chronic mercurial intoxication have three severity degrees, in the light degree disorders patients demonstrate lower amplitude of cognitive evoked potentials, poor long-term memory and associative thinking. Moderate cognitive disorders are characterized by decreased visual, long-term memory, concentration of attention, poor optic and spatial gnosis. Marked cognitive disorders with chronic mercurial intoxication present with more decreased long-term, short-term, picturesque memory, poor intellect, optic and spatial gnosis and associative thinking.

    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. PMID:23820209

    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. PMID:27243456

    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

    During pregnancy skeletal lead is mobilized by maternal bone turnover and can threaten fetal development. The exact strategy suggested to women of childbearing age, who were chronically exposed to lead, and, thus, have high bone lead burden, is not well established. We describe 4 years of follow-up of a 29-year-old woman with chronic lead intoxication. We (a) advised her to delay conception until 'toxicological clearance', (b) treated her with multiple courses of lead chelator, DMSA, and (c) prescribed oral calcium. Patient had low blood lead and protoporphyrin level during pregnancy until delivery. Delaying conception, lead chelation, and calcium supplementation can decrease fetal exposure. PMID:20459344

    Rats were administered D-amphetamine repeatedly for 4 days. After day 1 of treatment, the amphetamine-induced increases in ambulation, rearing, and stereotyped activity were augmented. However, after 4 days treatment, the rearing and ambulatory responses became attenuated while the stereotyped activities remained augmented. Micro-injection studies revealed that both the augmentation and attenuation of nonstereotyped ambulation were generated from the nucleus accumbens. The augmentation of stereotyped behaviors was generated from the caudate nucleus. Chronically treated animals who were administered 0.7 but not 1.0 mg/kg apomorphine showed augmented behavioral response. Chronic amphetamine treatment significantly decreased (3H) spiroperidol binding in both the nucleus accumbens and caudate nucleus. However, no effect on the DA-stimulated adenyl cyclase activity was observed in either brain region. It is concluded that repeated D-amphetamine administration selectively augments and attenuates D-amphetamine-induced behaviors and that these selective effects are mediated by different dopamine systems.

    A 62-year-old man was hospitalized for recent renal colic and neurologic disorders. Routine biochemistry indicated the presence of hypercalcemia (serum total calcium = 15.3 mg/100 mL) and renal failure (serum creatinine = 3.72 mg/100 mL). The patient reported that he had been on treatment with a slow-release multivitamin preparation containing vitamin D and vitamin A, administered by i.m. injection. Plasma 25-OH vitamin D was > 150 ng/mL (normal range 16-74 ng/mL), plasma 1,25-(OH)2 vitamin D was 32.5 pg/mL (normal range 14-60 pg/mL), plasma parathyroid hormone 1.3 pg/mL (normal range 10-65 pg/mL). There were calcifications of left and right iliac artery at abdomen x-ray. Ultrasound and computed tomography of the glutei showed alterations of skeletal muscle and calcifications. Immediate treatment with infusion of isotonic saline, furosemide and prednisone induced rapid control of hypercalcemia and renal failure. Chronic treatment per os was discontinued after six months. The patient reported that the treatment with vitamin D had been prescribed by a physician also to his wife (55-year-old). For the woman, routine biochemistry indicated the presence of hypercalcemia (serum total calcium = 11.3 mg/100 mL) and renal failure (serum creatinine = 1.8 mg/ mL). Plasma 25-OH vitamin D was > 150 ng/mL, plasma 1,25-(OH)2 vitamin D 47.9 pg/mL, plasma parathyroid hormone was 2.5 pg/mL.

    The dialysis encephalopathy syndrome (DES) consists of altered mental status, communication difficulty, seizures and myoclonus. It has been attributed to elevated serum aluminium (A1) levels. Two undialysed patients with chronic renal failure who presented with the characteristic syndrome are reported. The first, a 48 year old female, had used A1 containing phosphate binders for two years. Her serum A1 level was 25.34 mumol/L. Despite treatment with desferoximine and dialysis, she died. Necropsy revealed elevated A1 levels in the cerebral cortex (19 mcg/gm) and spongioform change in the outer three cortical layers. The second patient, a 46 year old woman, had a serum A1 of 8.70 mumol/L. She had never taken A1 containing phosphate binders but had taken several grams/day of citrate for at least six months. Treatment with haemodialysis and discontinuation of the citrate produced a resolution of symptoms and return of the A1 level to normal. During two years of haemodialysis there has been no recurrence.

    Thinner sniffing is popular among school children in Asian countries because it is readily available at low cost. Besides its toxicity to major organs, thinner inhalation is associated with various burn accidents. Four teenagers were admitted to the Burns Unit of the Prince of Wales Hospital over the period of 1996-1997. They sustained 3-25% TBSA flame burn and two of them had inhalation injuries as a result of the ignition of a cigarette during thinner sniffing. None of them had evidence of thinner intoxication as shown by blood tests. In the management of their acute burn injuries, their hidden social and family problems were explored. With the cooperation of different disciplines, early psychosocial intervention was given and their behavioral and psychological disturbances were successfully managed. PMID:9915679

    Taking a practical forensic case that provided an opportunity, an attempt was made to prove that paint thinner had been ingested by the victim. One ml of standard thinner solution, which was prepared by mixing toluene, ethyl acetate, and isobutanol, was given by gavage to rats, after which, on sacrifice of the animals, the distribution of thinner components in the body tissue and in the gastric contents was examined by gas chromatography, using the salting-out technique and the headspace method. Three thinner components and ethanol, a metabolite of ethyl acetate, were found to be present in the gastric contents, whereas only toluene was found in the blood and in the other tissue. From these results we thus have concluded that paint thinner taken can be proved by detecting the presence of ethyl acetate and isobutanol together with toluene in the stomach, whereas only toluene can be detected in the body fluids and the other tissue.

    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.

    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. PMID:26902358

    Few experiments have been carried out to evaluate the effects of toxic industrial substances such as the solvents on operant behavior. Laboratory rats trained in a mult FR DRL reinforcement schedule showed a differential impairment in performance when exposed to various doses of paint thinner in the experimental chamber, the FR performance being more sensitive to the solvent than DRL responding. Another study of rats working under a FI schedule suggested that the effects of paint thinner are rate-dependent, a finding which suggests a similarity of thinner with the amphetamines in regard to the behavioral effect. Two other experiments addressed to the behavioral effects of chronic exposure to the solvent showed a decrease in locomotor activity and an impaired acquisition of a complex temporal discrimination task in laboratory rats exposed to paint thinner during four, eight of sixteen weeks. These findings are suggestive of brain dysfunction associated with thinner inhalation but further experiments are needed for more definite conclusions. PMID:7442918

    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

    The aims of this study were to evaluate whether chronic intoxication with mercury chloride (HgCl2), in a low concentration over a long time, can be deposited in the central nervous tissue and to determine if this exposure induces motor and cognitive impairments. Twenty animals were intoxicated for 45 days at a dose of 0.375 mg/kg/day. After this period, the animals underwent a battery of behavioral tests, in a sequence of open field, social recognition, elevated T maze and rotarod tests. They were then sacrificed, their brains collected and the motor cortex and hippocampus dissected for quantification of mercury deposited. This study demonstrates that long-term chronic HgCl2 intoxication in rats promotes functional damage. Exposure to HgCl2 induced anxiety-related responses, short- and long-term memory impairments and motor deficits. Additionally, HgCl2 accumulated in both the hippocampus and cortex of the brain with a higher affinity for the cortex. PMID:25198682

    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.

    A 38-year-old Caucasian male, reportedly missing for four days, was found dead 40 feet down a steep ravine, apparently after jumping down the cliff. Two rectangular cans of paint thinner, 1-qt and 1-gal sizes, were found in his vehicle at the top of the cliff. The autopsy report indicated that the decedent was normal except for the heart and myocardium, the lung parenchyma, and the gastric and esophageal mucosa. The stomach contents revealed a brownish liquid with a nearly clear, thick, oily film, and the small and large bowels showed oily liquid with a strong odor of a petroleum distillate. Toxicological analysis was negative for ethanol and common drugs of abuse. Valproic acid, diphenhydramine, and norsertraline where found in therapeutic concentrations, and sertraline, diazepam, and nordiazepam were found in subtherapeutic levels. Bupropion metabolites were also detected. Static adsorption-elution, commonly used in fire debris analysis, was used to examine the brain, liver, lung, blood, and urine. A liquid-liquid extraction was performed on the vitreous humor. The stomach contents and samples from the paint thinner cans were diluted with carbon disulfide. All but the blood and vitreous contained a medium petroleum distillate. The stomach content was consistent with the liquid from the one-gallon can. Chromatograms suggest differential metabolism and/or distribution among the different organs. PMID:12423013

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

    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

    Intentional inhalation and occupational exposure are two ways humans are exposed to thinner, a widely employed solvent in industry. Inhalation of thinner induces toxic effects in various organs, with the cerebellum being one of the most affected structures of the CNS. The aim of this work was to describe specific structural alterations of cerebellum Purkinje cells in rats following exposure to thinner for 16 weeks. A histological analysis of the cerebellum of solvent-exposed rats revealed swollen Purkinje cell dendrites surrounded by empty space, and electronic microscopy showed an increase in the number of subsurface cisterns (SSCs) within their dendritic processes. After a period of non-exposure, the number of SSCs decreased without reaching normal levels, suggesting a degree of plasticity. Purkinje cell SSCs, which are derived from smooth endoplasmic reticulum, contain inositol trisphosphate receptors (IP3Rs), ryanodine receptors (RR), and a recently identified characteristic cluster of large conductance calcium-activated potassium (BKCa) channels. We found that SSCs in Purkinje cell dendrites were closely associated with mitochondria, and immunofluorescence microscopy showed higher levels of RR and calbindin receptors (CB), in Purkinje cells of exposed than normal rats. These changes are probably related to behavioral manifestations of cerebellar alterations, such as imbalance and ataxia, consistent with the suggested involvement of increases in SSCs in ataxia in rats and humans. This increase in SSCs, taken together with the localization of RR, IP3R and BKCa proteins in this structure, suggests altered intracellular calcium-buffering processes in the Purkinje cells of thinner-exposed rats.

    A 40-year-old, previously healthy man presented with a subacute coordination disorder and intermittent paraesthesias of the right arm that had begun several months before and had disappeared spontaneously within a few weeks. Neurological examination showed a mildly flattened nasolabial fold on the right side and subtle hypertonia of the right arm. A CT-scan of the brain revealed calcifications in the left caudate nucleus and putamen. Cerebral MRI showed markedly enlarged Virchow-Robin spaces bilaterally in the basal ganglia and extensive periventricular white matter lesions. The differential diagnosis of these radiological findings included carbon monoxide intoxication. Ancillary investigations excluded other causes for the radiological abnormalities, and a defective gas stove that produced carbon monoxide was found in the patient's house. Although carbon monoxide poisoning is relatively rare in the Netherlands, it remains important to be alert to the possibility of such exposure. Radiological findings, notably bilateral lesions of the basal ganglia, may point in the direction of the proper diagnosis. PMID:17472119

    Histological studies of oral cavity mucosa and salivary glands in subjects with chronic alcoholic intoxication revealed changes at the surface of the tongue and in the glandular tissues. Specific features of chronic alcoholic intoxication include acinar and ductal hyperplasia, reduction of the adipose tissue mass in salivary gland stroma, predominance of T-lymphocytes in hard palate minor salivary glands and B-lymphocytes in the stroma of labial minor salivary gland, the absence of plasma cells in the stroma of hard palate minor salivary glands and labial mucosa. Leukoplakia, dysplasia, and hyperplasia of the basal epithelial layer of oral cavity mucosa are considered to be the signs of long-term (over 12 months) alcohol consumption. PMID:21866840

    Chronic administration of 50% ethanol in a dose of 8 g/kg produces a toxic effect on functional activity of cardiomyocyte mitochondria, which manifested in decreased rates of respiration and oxidative phosphorylation. Structural GABA analogue Citrocard (phenibut citrate) and reference preparation piracetam in doses of 50 and 200 mg/kg, respectively, prevented the damaging effect of alcohol, which was seen from increased indexes of oxidative phosphorylation in treated animals compared to the control group.

    In the present study, we explore the protective effects of Citrus aurantium L. extract (CAE) against acute and chronic CCl4-induced hepatotoxicity. The quantitative analysis of CAE was performed using HPLC-UV to determine the nobiletin content was approximately 27%. For the acute model, the male ICR mice were orally treated with water, silymarin (positive control, 200 mg/kg) and CAE (50 and 200 mg/kg) for 3 days prior to CCl4 (1 mL/kg, 50% v/v in olive oil) IP injection. For the chronic model (n = 6/group), the mice were treated with each treatment for 28 consecutive days and CCl4 (1 mL/kg, 20%) was injected twice a week. In both the acute and chronic models, the CCl4 alone treated group showed histopathologic alterations with a significantly increase in serum hepatic enzyme levels together with a disrupted anti-oxidative status. In contrast, the CAE treatments restored pathologic alterations and recovered the oxidative status by enhancing antioxidant enzymes and reducing lipid peroxidation levels. Furthermore, CAE enhanced nuclear factor E2-related factor 2 (Nrf2) and its related cytoprotective signals, including NAD(P)H quinone oxidoreductase 1, UDP-glucuronosyltransferase, and γ-glutamylcysteine synthetase. Taken together, the present study demonstrates that CAE exerts a protective effect against CCl4-induced hepatotoxicity with its anti-oxidant, anti-inflammatory, and anti-apoptotic activity.

    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. PMID:21991179

    Itai-itai disease is thought to be the result of chronic cadmium (Cd) intoxication. We examined 23 autopsy cases of itai-itai disease and 18 cases of sudden death as controls. Urine and blood samples from 10 patients were collected before they died and revealed the presence of severe anemia and renal tubular injuries. Undecalcified sections of iliac bone were stained with Aluminon reagent, and ammonium salt of aurintricarboxylic acid, and Prussian blue reagent in all cases of itai-itai disease. These two reagents reacted at the same mineralization fronts. X-ray microanalysis revealed the presence of iron at mineralization fronts in itai-itai disease. Five patients showed evidence of hemosiderosis in the liver, spleen, and pancreas, probably as a result of post transfusion iron overload. Renal calculi and calcified aortic walls were also stained with Prussian blue reagent in several patients. Neither ferritin nor transferrin were visualized at mineralization fronts in itai-itai disease by immunohistochemical staining. These results suggest that iron is bound to calcium or to calcium phosphate by a physicochemical reaction. A marked osteomalacia was observed in 10 cases of itai-itai disease by histomorphometry. Regression analyses of data from cases of itai-itai disease suggested that an Aluminon-positive metal inhibited mineralization and that renal tubules were injured. Since bone Cd levels were increased in itai-itai disease, it is likely that renal tubules were injured by exposure to Cd. Therefore, stainable bone iron is another possible aggravating factor for osteopathy in itai-itai disease, and a synergistic effect between iron and Cd on mineralization is proposed.

    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. PMID:17406072

    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

    The complications encountered in caring for 185 patients intoxicated with barbiturates were reviewed. The population consisted of 142 patients with long-acting barbiturate concentrations of 8 mg per 100 ml or greater, 20 patients with short-acting barbiturate concentrations of 3 mg per 100 ml or greater and 23 consecutive patients with short-acting barbiturate intoxication referred for monitoring. Pneumonia was the major cause of morbidity and mortality and correlated best with the initial depth of coma and the use of an endotracheal tube in treatment. Cardiovascular instability manifested by pulmonary edema was the next leading cause of morbidity and mortality and correlated best with the initial depth of coma and the quantity of intravenous fluid administered. In retrospect, use of eliminative measures such as dialysis would probably not have altered the outcome in most of the patients who died and attempts at forced diuresis may have contributed to several deaths. Particular emphasis should be placed on the problems of sepsis and fluid therapy in the management of these patients. PMID:1258466

    HAS (high alcohol sensitive) and LAS (low alcohol sensitive) lines of rats have been selectively bred based on their differences in ethanol-induced sleep time. In the present study, the two lines were compared to examine another central effect of acute alcohol intoxication: namely, hypothermia. As the disturbances in membrane microorganization have been associated with the nervous system's sensitivity and tolerance to ethanol, the synaptic plasma membrane fluidity and acute sensitivity to ethanol were also evaluated by fluorescence polarization of DPH probes in the HAS and LAS rats. The two lines did not differ in the magnitude of their hypothermic response after acute injection of ethanol (3 g/kg body wt, i.p.). Although membranes in the HAS line were slightly more rigid than in the LAS line, the level of membrane disordering after acute ethanol addition was identical for the two lines in the region examined with the DPH probe. Following the chronic intoxication of the rats, the two lines developed tolerance to the hypnotic and hypothermic effects of ethanol. In the same way, a membrane resistance (i.e. tolerance) to the disordering effect of acute ethanol addition developed in the region probed with DPH. In general, the LAS line showed a more pronounced level of tolerance than the HAS line at both the functional and membrane level. These results suggest that different measures used to assess the depressant action of ethanol, such as sleep time, hypothermia or membrane disordering, may not be related and could indicate different genetic origins.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7695793

    The present study describes the dose-dependent effect of taurine, an amino acid and a known antioxidant, either alone or in combination with meso 2,3-dimercaptosuccinic acid (DMSA) in the treatment of subchronic lead intoxication in male rats. The effects of these treatments in influencing the lead-induced alterations in haem synthesis, hepatic, renal or brain oxidative stress and lead concentration from soft tissues were investigated. Exposure to lead produced a significant inhibition of blood delta-aminolevulinic acid dehydratase (ALAD) activity, reduction in glutathione (GSH) and an increase in zinc protoporphyrin (ZPP) suggesting an altered haem synthesis pathway. Only DMSA was able to increase the activity of ALAD, while both taurine and DMSA were able to significantly increase GSH level towards normal. Animals treated with taurine significantly reduced the alterations in some of the biochemical parameters indicative of oxidative stress. Thiobarbituric acid reactive substance (TBARS) levels reduced significantly in liver, kidney and red blood cells, while GSH level increased. Activity of superoxide dismutase (SOD) also showed an increase in blood and brain in animals treated with taurine. The data also provided a promising role of taurine during chelation of lead by potentiating the depletion of blood, liver and brain lead compared to DMSA alone. It can thus be concluded from the study that concomitant administration of an antioxidant could play a significant and important role in abating a number of toxic effects of lead when administered along with the thiol chelators.

    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. PMID:24964748

    Thinner is a very potent neurotoxic compound which damages both the central and peripheric nervous system, as well as the rest of the organism, when it is used or inhaled spontaneously chronically. 20 Wistar rats were used. They inhaled 1.5 ml of thinner per day and were sacrificed by pairs upon days 7, 15, 30, 45, 60, 75, and 90. Four of them were sacrificed after suspending the inhalation 15, 30, 60 and 90 days later so as to study the process of recuperation. The hind legs were fixated in 10% formaldehyde for 15 days. Fragments of sciatic and crural nerves were included in paraffin and histological cuts were performed both in transversal and longitudinal sections of 5 to 7 micra. Techniques for myelin and argento-auric ones were performed. Incipient lesions are described as well as intermediate and terminal ones produced after having inhaled 45 ml of thinner for 30 days. The myelin sheath shows edema, ballooning and destruction due to lysis after inhaling 135 ml in 90 days. In a parallel manner the nerve fibers show edema, irregular thickening and after inhaling 135 ml in 90 days there is atrophy or disintegration. A partial regeneration is produced if inhalation is suspended after 30 days and 30 more days are allowed for recuperation, when some Schwann cells are still active. We believe that the lesions which begin to appear on the myelin sheath occur because thinner is a fat solvent, fats being important elements in their structure and the nerve fiber injury may be secondary to the demyelinization, or due to destruction of the central neuron from which they originate.

    This study was designed to evaluate the epidemiology and outcome of burn injuries due to paint thinner in a local burn center. During a 10-year period, 32 patients were admitted to our Burn Unit for paint thinner thermal burn. Patients were reviewed regarding the age, sex, etiologic factors, extent and localization of burn, treatment methods, length of hospitalization, and results. There were 30 males and 2 females. The mean age of patients was 25.9 +/- 11 years. The most common etiologic factor was kindling a fire with paint thinner. The mean extent of burn was 33.6 +/- 24% of the total body surface area. All patients sustained burn injury on the face, arms, and hands and five patients among them had extended burn areas on the trunk and/or lower extremity. The mean length of hospitalization for the survivors was 34.5 +/- 21.6 days. Twenty-eight patients were treated by early excision and split-thickness skin grafting. In four patients, burn wounds were healed by conservative management. Five patients with burn size of over 75% of the total body surface area died. In conclusion, paint thinner may be the cause of a catastrophic thermal injury and should not be used for the purpose of kindling fire. PMID:15019124

    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. PMID:26688578

    After an accidental oral intake of a paint thinner, the constituents were identified in stomach content using headspace gas chromatography. The composition indicated ingestion of a commonly used thinner containing 60-70% toluene, 20-25% n-butylacetate and 10-15% of ethanol. A toluene concentration of 22.0 mg/kg was measured in serum in contrast to n-butylacetate which was not detected. Ethanol concentration was 1.85 g/kg, most of this was due to ethanol ingestion before the intake of thinner. The half life of toluene in serum was 8.5 h initially, which increased to 14 h after 19 h. An effect on liver function was demonstrated by increased activity of serum transaminases. Compared with the upper normal limits ASAT and ALAT were increased by 6 and 2.5 times, respectively. For both parameters the highest activity was seen 40 hours after admission and normal levels were achieved after 7 days. It is concluded that toluene is readily absorbed by ingestion of toluene-containing thinners, and that the function of the human liver is transiently affected. For screening purposes gas chromatography proved to be a useful method for the analytical diagnosis in cases of organic solvent intoxication. The use of the headspace technique further improved the speed of analysis and eliminated contamination of the gas chromatographic system. PMID:3868371

    A wide range of conventional chelating agents have been screened for (a) antidotal activity in acute cadmium poisoning and (b) ability to reduce aged liver and kidney deposits of cadmium. Chelating agents belonging to the dithiocarbamate class have been synthesized and tested in both the acute and chronic modes of cadmium intoxication. Several dithiocarbamates, not only provide antidotal rescue, but also substantially decrease the intracellular deposits of cadmium associated with chronic cadmium intoxication. Fractionating the cytosol from the livers and kidneys of control and treated animals by Sephadex G-25 gel filtration clearly demonstrates that the dithiocarbamates are reducing the level of metallothionein-bound cadmium. However, the results of cell culture (Ehrlich ascites) studies designed to investigate the removal of cadmium from metallothionein and subsequent transport of the resultant cadmium complex across the cell membrane were inconclusive. In other in vitro investigations, the interaction between isolated native Cd, Zn-metallothionein and several chelating agents was explored. Ultracentrifugation, equilibrium dialysis, and Sephadex G-25 gel filtration studies have been carried out in an attempt to determine the rate of removal of cadmium from metallothionein by these small molecules. Chemical shifts for the relevant cadmium-dithiocarbamate complexes have been determined using natural abundance Cd-NMR.

    Organic solvents cause injury to lipids of neuronal and glial membranes. A well known characteristic of workers exposed to thinner is optic neuropathy. We decided to look for neurophysiologic signs of visual damage in patients identified as thinner abusers. Pattern reversal visual evoked potentials was performed on 34 thinner abuser patients and 30 controls. P-100 wave latency was found to be longer on abuser than control subjects. Results show the possibility of central alterations on thinner abusers despite absence of clinical symptoms. PMID:8987190

    Paint thinner is a commonly used industrial solvent with considerable potential for abuse by inhalation. Paint thinner is taken into the body by inhalation or by contact with the skin. Paint thinner is oxidized gradually by cytochrome P450-dependent monooxygenase and consequently free radicals are produced. In the present study we measured plasma malondialdehyde (MDA, a product of lipid peroxidation) levels as an indicator of oxidative damage and activity levels of antioxidant enzymes gluthatione peroxidase (GSH-Px) and superoxide dismutase (SOD) in erythrocytes of a group of people (n = 18) working with paint thinner. The control group was composed of 18 healthy adults. There was a statistically significant (p < 0.001) increase in MDA (2.0+/-0.7 nmol ml(-1)) and GSH-Px (86.5+/-16.6 U g(-1) Hb) activity levels in people working with paint thinner compared with control subjects (MDA: 1.0+/-0.3 nmol ml(-1); GSH-Px: 53.9+/-14.5 U g(-1) Hb). Similarly, there was also an increase (p < 0.05) in the SOD levels (1079+/-214.6 U g(-1) Hb) of people working with paint thinner compared with controls (953.3+/-46.7 U g(-1) Hb). Based on our results, it can be concluded that paint thinner inhalation may increase lipid peroxidation and consequently induce antioxidant enzymes. PMID:11180289

    From August to December of the year 2000 we ascertained 7 rapid deaths because of acute intoxication with tablets colloquially called Ufo. There were five men and two women aged from 20 to 29 (average 24) years. Analytic tests showed that one tablet of Ufo contains 40 mg of paramethoxyamphetamine, 1.0 mg of amphetamine, 0.05 mg of methamphetamine, 0.03 mg of 3-4-methylenedioxymethamphetamine. The levels of paramethoxyamphe-tamine in the blood of the deceased, determined by gas chromatography, were from 0.68 to 10.0 (approx. 3.2) mg/L and in the urine from 16 to 64 (approx. 35) mg/L.

    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

    Postmortem changes of thinner components in body tissues were examined in rats, orally given 1 ml of standard thinner solution, which was prepared by mixing toluene, ethyl acetate and isobutanol in the proportion of 8:1:1. Analysis was made by gas chromatography combined with the head space method. Three thinner components and ethanol, a metabolite of ethyl acetate, were detected in the gastric contents of all rats up until 48 hours after death. An increase in the concentration of toluene was found in the blood, lung, kidney, liver, brain and abdominal muscle with the lapse of time. On the other hand, no changes were observed in the thigh muscle throughout the 48-hour period. Isobutanol showed a similar increasing pattern to toluene, with little or no changes in the brain or in the thigh muscle. Ethyl acetate was not detected in any tissues throughout the study but it was found in the gastric contents. The results indicate that every thinner component ingested, gradually diffuses into the surrounding tissues through the stomach wall after death, and that only muscle tissue remote from the abdominal cavity, together with the gastric contents, should be analyzed for a correct diagnosis of thinner ingestion.

    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.

    Manganese regulates many enzymes and is essential for normal cell function. Chronic manganese intoxication has an insidious and progressive course terminating to atypical parkinsonism with little therapeutic efficacy. For subjects with chronic manganese exposure such as welders, manganese intoxication can be detected early based on the presence of hyperintensity in the globus pallidus on T(1)-weighted MRI and abnormally high urinary excretion of manganese with a chelating agent even in cases of normal serum/urine level of manganese.

    Many compounds, when absorbed or ingested, can cause harm to animals and people. Veterinarians are commonly faced with companion animals that have been exposed to these harmful compounds. Most poisonings are the result of curious exploration by the pet and a quest to taste everything in their path. Some poisonings are the result of malice, and many simply result from owner ignorance when pets are given medications without regard to dose or compatibility. It is the responsibility of the emergency clinician encountering these cases to prevent further exposure to the poison, enhance its elimination, and provide supportive and antidotal care. Antidotes when available are of little value if the animal has lost any vital functions. It is the purpose of this article to focus on the emergency management of intoxications by reviewing the general principles of triage and emergency care, and to discuss available procedures to stop the exposure, prevent further absorption, and hasten elimination of poisons from the patients body.

    In the northeast of Portugal, paraquat intoxication is common. We report 31 patients, admitted at our institution from April 1997 to June 2004, with suspected paraquat intoxication. Thirty cases had suicidal intention and all have ingested the toxic by mouth. Treatment consisted of skin and digestive decontamination with gastric washing and activated charcoal or Fuller's Earth. The first medical care was performed after 1 h 14 min at median [9 min-11 h 26 min]. By laboratory measurement (n=13) and/or clinical observation (n=11) it was possible to confirm the gastrointestinal absorption of paraquat for 24 patients (17 male-7 female; 49 +/- 17 years). The estimated ingested volume was higher for 15 non-survivors relatively to nine survivors (170 +/- 60 mL vs 25 +/- 10 mL; P<0,001). Initial serum paraquat of seven non-survivors was also higher than the serum level of six survivors (8.3 +/- 6.9 mg/L vs 0.4 +/- 0.3 mg/L; P < 0.01). Remarkably, all patients with serum paraquat higher than 1.7 ml/l did not survived. The paraquat urine level, simultaneous to the first serum determination, was higher for six survivors (38 +/- 37 mg/L) comparing with four non-survivors patients (465 +/- 536 mg/L; P<0.04). Hemoperfusion with activated charcoal was performed after December 1997 until June 2004 for 25 patients. Twenty of the 24 patients confirmed for paraquat intoxication were treated with this technique (12/15 of the non-survivors and 8/9 of the survivors; p=NS). Total number of sessions was identical (2.0 +/- 1.0 vs 1.5 +/- 1.2; P=NS), total time of hemoperfusion was higher (7 h 58 min vs 5 h 37 min; P=0.07) but the beginning of the first session was later (7 h 44 min vs 4 h 18 min; P=0.04) for the survivors. Clinical signs and laboratory analysis were collected at admission trying to detect markers of prognostic survival value.

    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.

    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. PMID:18575299

For a thinner-THGEM of thickness 0.2 mm, with hole diameter 0.2 mm, pitch 0.2 mm and narrow (5-10 μm) rim, the performance of gain versus high voltage with different gas mixtures have been studied using 5.9 keV X-rays. In general, a gain of around 3 × 103 was obtained with a single board in Ar/iC4H10, and gains higher than 104 were obtained in Ne mixture at lower voltage. The dependence of the energy resolution on the drift and induction electric fields was measured and an energy resolution of 15.9% was obtained. A curved thinner-THGEM chamber with one-dimensional readout has been assembled for use in the diffraction studies at the Beijing Synchrotron Radiation Facility (BSRF). A cosmic-ray muon hodoscope based on thinner-THGEM was developed as a teaching experiment for the Graduate University of the Chinese Academy of Sciences (GUCAS).

    A 55-year-old man came to the hospital with a bleeding wound on his tongue. The coating of his tongue was green, and his sputum was red. Because an increased international normalized ratio-value was measured, a blood sample was sent to our laboratory with the suspicion of coumarin intoxication. Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) analysis confirmed the poisoning was by bromadiolone, with its maximum serum concentration at 440 microg/L. The analysis of further samples resulted in a calculated elimination half-life of 140 h. The analytical method described was developed for the determination and quantitation of bromadialone using LC-MS. This method is suitable for the simultaneous identification and quantitation of 10 indirect anticoagulants in human serum, which include five superwarfarins (brodifacoum, bromadiolone, difenacoum, difethialone, and flocoumafen) as rodenticides licenced in Germany and five other vitamin K antagonists (acenocoumarol, coumatetralyl, coumachlor, phenprocoumon, and warfarin). The method is based on an acidic (pH 4.2) liquid-liquid extraction followed by LC-ESI-MS analysis. Analytical separation was carried out using an Atlantis C18 column (2.1 x 20 mm, 3 microm). The mobile phase consisted of methanol/0.1% formic acid; the flow rate was 0.6 mL/min, and the time needed for analysis was 5 min. The lower limit of quantitation was 5 microg/L (signal-to-noise > 10). PMID:16803669

    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. PMID:25413263

    Vitamin D intoxication (VDI) may result from supplementation rarely, but it has been reported more frequently in recent years. This may be attributable to an increase in vitamin D supplement intake due to an understanding of the role of vitamin D (25OHD) in the pathogenesis of several diseases. The symptoms and findings associated with VDI are closely related to serum calcium concentration and duration of hypercalcemia. In patients with VDI, hypercalcemia, normal or high serum phosphorus levels, normal or low levels of alkaline phosphatase (ALP), high levels of serum 25OHD, low serum parathyroid hormone (PTH), and high urine calcium/creatinine are usually present. Serum 25OHD levels above 150 ng/ml are considered as VDI. The main goal of treatment for VDI is correction of the hypercalcemia. When the calcium concentration exceeds 14 mg/dl, emergency intervention is necessary because of the adverse effects of hypercalcemia on cardiac, central nervous system, renal, and gastrointestinal functions. However, since vitamin D is stored in fat tissues, effects of toxicity may last for months despite the removal of the exogenous source of vitamin D. Treatment for VDI includes: discontinuation of intake, a diet with low calcium and phosphorus content, intravenous hydration with saline, loop diuretics, glucocorticoids, calcitonin, and bisphosphonates. In conclusion, the diagnosis of vitamin D deficiency rickets (VDDR) without checking serum 25OHD level may cause redundant treatment that leads to VDI. All patients who are clinically suspected of VDDR should be checked for serum vitamin D status and questioned for previous vitamin D administration before starting vitamin D therapy. On the other hand, parents of all infants should be asked whether they are using dietary or oral supplements, and serial questioning may be required during supplementation to avoid excessive intake.

    The transmammary movement of lead is exemplified by increased levels of lead in mothers milk. Control animals had mean levels of 0.18 p.p.m. of lead in their milk, while the lead experimental mothers averaged approximately 0.60 p.p.m. (range from 0.30 to 1.30 p.p.m.). In most cases, the first milk expressed from the mother contained more lead than subsequently obtained samples. A comparison of blood lead values between lead experimental mothers and their offspring were shown to be generally within 10-15% of one another at birth, and significantly different (p < 0.001) from controls. Zinc protoporphyrin concentrations were significantly different (p < 0.001) at birth between lead experimental infants and control infant. This illustrates that lead, is indeed, transplacental and disrupts the normal mechanisms responsible for heme biosynthesis in utero.

    Over 2.5 million accidental and intentional drug-related poisonings are reported annually in the United States. Early diagnosis and management of patients who present with acute intoxication can significantly reduce both morbidity and mortality. The initial evaluation of patients with suspected or proven intoxications should focus on hemodynamic stability, mental status, and respiratory function. However, early recognition of toxic ingestion is paramount to implementing life-saving treatments. Important historical clues are often found in a social history that considers intravenous drug use, alcohol use, and any access or exposure to illicit substances. A patient's medication list should also be scrutinized for psychoactive or sedative medications, such as tricyclic antidepressants or opioids. In this article we present case-based discussions of the specific diagnosis and management of 5 commonly occurring acute intoxication syndromes. PMID:20877175

    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. PMID:27506091

    Post mortem diffusion of paint thinner (toluene/ethyl acetate/isobutanol 8:1:1 v/v) from gastric residue (25 ml or 100 ml) and airways contamination (25 ml) was assessed in a human cadaver model, with sampling after 24 h at room temperature. Four torso blood samples showed less toluene diffusion after gastric instillation (0.5-3.8 micrograms/ml) than after tracheal instillation (10.5-421 micrograms/ml). Isobutanol diffused more readily than toluene with four torso blood samples 1.8-256 micrograms/ml after gastric instillation and 26-576 micrograms/ml after tracheal instillation. Following 25 ml gastric instillation, toluene concentrations (microgram/ml or microgram/mg) were: pericardial fluid 0.7-4.0; bile 0.5-0.6; urine 0-0.6; brainstem 1.1; lung 0.4-4.4; liver 0-162; spleen 0.6-0.7; kidneys 0.4-0.6; peri-renal fat 0.3-30.3; psoas muscle 0.3-0.8; concentrations of toluene and isobutanol were markedly higher in the left lobe of the liver than the right. Ethyl acetate was mostly undetectable in tissue samples but variably present in five blood samples: 0-21.2 micrograms/ml following 25 ml or 100 ml gastric instillation and 0-198 micrograms/ml following 25 ml tracheal instillation. Ethyl acetate was always detectable in pericardial fluid but not always detectable in gastric contents. We conclude that post mortem diffusion of toluene from gastric residue or airways contamination is unlikely to compromise the analytical validity of femoral venous blood samples, brain, or liver from deep within the right lobe. Analysis of pericardial fluid and gastric contents allows identification of ethyl acetate and isobutanol thus implicating thinner solution. PMID:8635764

    The status of xanthine oxidase in ethanol-induced liver injury has been investigated in the rat, by acute and chronic ethanol treatments. A 38% increase of the enzyme O-form was observed after repeated ethanol administration. Chronic intoxication caused a significant decrease of total xanthine oxidase activity after both prolonged ethanol feeding and life span ethanol ingestion. The intermediate D/O-form of xanthine oxidase (that can act either as an oxidase or as a dehydrogenase, being able to react with O2 as well as with NAD+ as electron acceptor) increased 5.5-fold after prolonged ethanol feeding.

    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 prevalence of carbon monoxide intoxication in the World shows that this is a common situation. In Portugal, there are no concrete data available in literature and its incidence remains unknown. Currently, the use of hyperbaric oxygen is a valid therapeutic for carbon monoxide poisoning management. However, its effectiveness and its proper handling are still controversial. The first aim of this study was to estimate the incidence of carbon monoxide intoxication in Portugal and to analyze its demographic characteristics. The second objective of this work was to evaluate the possible change in the type of treatment applied in areas near de hyperbaric chamber of Unidade Local de Saúde de Matosinhos, since its opening in June 2006. To achieve these objectives, we conducted a survey on admissions data for carbon monoxide intoxication occured between January first, 2000 and December 31, 2007. These data was collected in seven hospitals and in the Administração Central do Sistema de Saúde, I.P. Nationally, 621 hospitalizations were recorded, which represents an incidence of 5,86/100000 in 8 years. In the seven hospitals, there were 93 hospitalizations due to carbon monoxide intoxication during the same period of time. There was a peak of incidence during winter, between November and March and there was a similar distribution in men (47,3%) and women (52,7%). Since June 2006, date of opening of the hyperbaric chamber, the Unidade Local de Saúde de Matosinhos, E.P.E. recorded a sharp increase in the number of hospitalization for carbon monoxide intoxication. The number of admissions in the 19 months after the chamber opening was double the number of all cases occurred in that institution in the 65 months prior. We concluded that, in Portugal, carbon monoxide intoxication is an uncommon situation but it´s still an important cause of hospitalization.

    Paint thinner has widespread use in industry. The use of thinner among children as a narcotic agent has become a social and health problem. There is some evidence that organic solvents may express their toxicity by the way of reactive oxygen species (ROS) induced cell damage. ROS has been shown to induce lipid peroxidation in biological membranes. This study examined peroxidative and histopathological changes in the rat lung, during 5 weeks of thinner inhalation. Significant increases were found in lipid peroxidation (MDA+4-DHA) levels related to the duration of inhalation. As opposed to increases in the lipid peroxidation levels, significant decreases in superoxide dismutase activities and glutathione levels were observed from the third inhalation week to the end of the fifth week. At the beginning of the inhalation slight inflammatory changes, intraalveolar and interstitial extravasation and oedema in lung parenchyma were noted. As the inhalation period extended, chronic inflammatory changes, alveolar epithelial proliferation, collapse, emphysematous changes and interstitial fibrosis in lung were detected. PMID:9782071

    Studies of protein excretion were undertaken in seven males, aged 35-42 years, who had more than 5 years exposure to industrial lead and had clinically established Pb intoxication. Heavy metal intoxication with Cd and Hg causes proximal tubular abnormalities, i.e., aminoaciduria, glycosuria, phosphaturia. Similar abnormalities occur in Pb intoxication except that the nature of the proteinuria remains controversial. Studies of urinary proteins included 24-hr urine protein excretion, dextran gel separations, sodium dodecyl sulfate-polyacryl-amide gel electrophoresis (SDS-PAGE), and ..beta../sub 2/ microglobulin (B/sub 2/M) measurements. Creatinine clearances, and serum B/sub 2/M concentrations were normal. Urine total protein distribution by SDS-PAGE and the B/sub 2/M excretion rate were also normal. These data imply that the nephrotoxicity of Cd and Hg are different than that of Pb. The authors speculate on what might account for this difference. This study suggests that when examining a population exposed to Pb, the finding of tubular proteinuria should alert investigators to search for the presence of other toxic agents.

    Hydrogen sulfide (H2S) is a hazard primarily in the oil and gas industry, agriculture, sewage and animal waste handling, construction (asphalt operations and disturbing marshy terrain), and other settings where organic material decomposes under reducing conditions, and in geothermal operations. It is an insoluble gas, heavier than air, with a very low odor threshold and high toxicity, driven by concentration more than duration of exposure. Toxicity presents in a unique, reliable, and characteristic toxidrome consisting, in ascending order of exposure, of mucosal irritation, especially of the eye ("gas eye"), olfactory paralysis (not to be confused with olfactory fatigue), sudden but reversible loss of consciousness ("knockdown"), pulmonary edema (with an unusually favorable prognosis), and death (probably with apnea contributing). The risk of chronic neurcognitive changes is controversial, with the best evidence at high exposure levels and after knockdowns, which are frequently accompanied by head injury or oxygen deprivation. Treatment cannot be initiated promptly in the prehospital phase, and currently rests primarily on supportive care, hyperbaric oxygen, and nitrite administration. The mechanism of action for sublethal neurotoxicity and knockdown is clearly not inhibition of cytochrome oxidase c, as generally assumed, although this may play a role in overwhelming exposures. High levels of endogenous sulfide are found in the brain, presumably relating to the function of hydrogen sulfide as a gaseous neurotransmitter and immunomodulator. Prevention requires control of exposure and rigorous training to stop doomed rescue attempts attempted without self-contained breathing apparatus, especially in confined spaces, and in sudden release in the oil and gas sector, which result in multiple avoidable deaths.

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. PMID:26563790

    This clinico-laboratory study showed that antihypoxant remaxol promoted normalization of lipid metabolism in acute peritonitis and significantly reduced membrane-destabilizing events. This resulted in rapid elimination of the inflammatory process in the abdominal cavity and lowering of the intensity of endogenous intoxication. This beneficial effect decreased the severity of myocardial lesions and resulted in the normalization of erythrocyte function. It is concluded that the regulatory action of remaxol on lipid metabolism is due to its ability to control free radicals in lipid peroxidation and reduce phospholipase A2 activity. PMID:23285765

Changes of these indices in ambustial disease of middle severity have witnessed a sufficiently compensated reaction of organism: of severe and extremely severe one--there were noted a deficiency of the organism antioxidant defense; and in stages of toxemia and septicotoxemia--attrition of the organism oxidant reserves and danger of the septic complications occurrence. Conduction of early surgical intervention have guaranteed maintenance of a ceruloplasmin content in stages of toxemia and septicotoxemia on the level of healthy persons, relief of the ambustial disease course, absence of critical metabolic intoxication and carbonyl stress, reduction of the septic complications rate in 1.5 times.

    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

    Alternative human bioassay procedures for uranium are being investigated. Aminoaciduria in uranium hexafluoride and uranium mill employees has been examined. Although not conclusive, the results suggest that chronic human urinary uranium concentrations of 30-50 ..mu..g L/sup -1/ produce marked changes in the amino acid excretion profile although no consistent patterns emerged. As part of a program to examine alternative bioassay techniques for occupationally exposed uranium workers and to assist in interpretation of amino acid obtained from human incident exposures, the authors have examined the occurrence of transient aminoaciduria following uranium intoxication in female rats.

    In 14,744 autopsy cases from an 18-year period 92 cases (of which 7 were ruled out because of decomposition were observed in which death was supposed to be due to direct acute alcoholic intoxication. In the police reports 81 persons were designated as chronic alcoholics or abusers of spirits. The blood alcohol level ranged between 2.04 and 4.92 o/oo. The cases studied were divided into two groups, one with low and the other with high lethal alcohol level. Fatty liver and cirrhosis were found with identical frequency in the two groups, whereas cardiac hypertrophy of obscure origin occurred markedly more often in the group with low lethal blood alcohol level. On the basis the possible mechanism of death in the cases with cardiac hypertrophy is discussed. Finally, the relation between the blood and urine alcohol concentrations observed in 72 cases is discussed. On the assumption that the water phase of the blood was 75 per cent of the total blood, death occurred in the persons without cardiac hypertrophy with fairly identical frequency either in the phase of absorption or the phase of elimination, whereas in the persons with cardiac hypertrophy death most often occurred in the phase of absorption. These statements should, however, be taken with some reservation, partly because the water phase of the blood may vary considerably post mortem (60-90 per cent) and partly because the urine alcohol concentration depends on serval variable factors.

    Paint thinners are organic-solvent complex mixtures frequently used by car painters around the world in industries and shops. Some studies have revealed the oxidative effect induced by thinner inhalation; however, its genotoxic effect is poorly studied. The aim of this study was to assess the cytotoxicity, genomic damage and DNA repair in vitro induced by commercial paint thinner 0.14 in human lymphocytes. Cytotoxicity was determined by cell-viability analysis with trypan blue after 4 h treatment with different thinner concentrations (0.025 to 1.2 µL/mL). Genomic damage was evaluated by means of the alkaline single-cell gel electrophoresis (SCGE; pH > 13) in treated cultures after 1 h with three low-cytotoxic thinner concentrations (0.05, 0.1 and 0.2 µL/mL). In order to evaluate the genomic DNA repair, one set of SCGE slides was prepared immediately after treatment, and another one was prepared after 4 h of liquid-holding recovery. A significant level of cytotoxicity was observed over the entire concentration range of paint thinner in lymphocytes (F = 175.98; p ≤ 0.001). In the SCGE % tail DNA assessment, a significant increase of lymphocyte genomic damage was evidenced (F = 72.32; p < 0.001). In addition, we found a significant decrease in the % tail DNA in thinner-treated cells after liquid-holding recovery period (all p < 0.05), demonstrating that DNA primary lesions induced by low-cytotoxic thinner concentrations are efficiently repaired. In conclusion, thinner components induce cytotoxicity and genomic damage in human lymphocytes under the study conditions, possibly by oxidative and alkylative DNA damage. PMID:24236478

    The monosodium glutamate (MSG) neonatal administration in mice provides a model of obesity with impaired glucose tolerance (IGT) and insulin resistance. However, the inflammatory profile of cytokines produced from fat tissue and its relationship to the metabolic dysfunction induced by MSG have not yet been revealed. The aim of this study was to establish the inflammatory profile attributed to MSG by measuring the expression of adipokines in visceral fat and serum of 19-week-old mice as well as the peroxisome proliferator-activated receptors alpha and gamma (PPARα and γ). Some metabolic and biochemical parameters were also quantified. The MSG increased mRNA expression of interleukin-6 (IL-6), tumour necrosis factor-alpha (TNFα), resistin and leptin, but adiponectin did not exhibit any changes. In addition, impaired glucose tolerance, increased levels of insulin, resistin and leptin were observed in serum. Both PPARα and PPARγ were activated in MSG-induced obese mice, which might explain its inflammatory profile. However, liver transaminases were severely depressed, indicating that MSG may also induce liver injury, contributing to inflammation. The MSG neonatal neuro-intoxication in mice may thus provide a model of obesity and inflammation characterized by the dual activation of PPARα and PPARγ, which might offer new insights into the mechanism of inflammatory diabetes in obesity leading to steatohepatitis, as well as a suitable model to study the role of new therapeutic agents to prevent or reduce insulin resistance, the inflammatory state and liver steatosis.

    Introduction. Cocaine, a widely used sympathomimetic drug, causes thermoregulatory and cardiac manifestations that can mimic a life-threatening thyroid storm. Case. A man presented to the emergency department requesting only cocaine detoxification. He reported symptoms over the last few years including weight loss and diarrhea, which he attributed to ongoing cocaine use. On presentation he had an elevated temperature of 39.4°C and a heart rate up to 130 beats per minute. Examination revealed the presence of an enlarged, nontender goiter with bilateral continuous bruits. He was found to have thyrotoxicosis by labs and was treated for thyroid storm and cocaine intoxication concurrently. The patient was ultimately diagnosed with Graves’ disease and treated with iodine-131 therapy. Conclusion. Cocaine use should be considered a possible trigger for thyroid storm. Recognition of thyroid storm is critical because of the necessity for targeted therapy and the significant mortality associated with the condition if left untreated. PMID:26425625

    Thinner is a substance that is used for industrial purposes and for drug abuse; addiction is of young people (average age, 7.5 years). Although the health problem of voluntary or nonvoluntary solvent sniffing is important, great attention has been paid to the epidemiology and pharmacology of paint thinner or industrial solvents inhalation, but studies at the morphological and biochemical level are scarce. This work describes the morphological changes in the lung, liver, kidney, adrenal glands, and central nervous system induced by short- (up to 4 weeks) and long-term (up to 14 weeks) periods of thinner inhalation in rats.

    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.

  15. Fatal Intoxication with Acetyl Fentanyl.

    Among the new psychoactive substances encountered in forensic investigations is the opioid, acetyl fentanyl. The death of a 28-year-old man from recreational use of this compound is reported. The decedent was found in the bathroom of his residence with a tourniquet secured around his arm and a syringe nearby. Postmortem examination findings included marked pulmonary and cerebral edema and needle track marks. Toxicological analysis revealed acetyl fentanyl in subclavian blood, liver, vitreous fluid, and urine at concentrations of 235 ng/mL, 2400 ng/g, 131 ng/mL, and 234 ng/mL, respectively. Acetyl fentanyl was also detected in the accompanying syringe. Death was attributed to recreational acetyl fentanyl abuse, likely through intravenous administration. The blood acetyl fentanyl concentration is considerably higher than typically found in fatal fentanyl intoxications. Analysis of this case underscores the need for consideration of a wide range of compounds with potential opioid-agonist activity when investigating apparent recreational drug-related deaths.

    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. PMID:26242570

    Cyanohydrins, also be called cyanoalcohols, are important industrial precursors to carboxylic acids and some amino acids. Acetone cyanohydrin (ACH) and formaldehyde cyanohydrin (glycolonitrile, FCH), which are the typical examples of cyanohydrins, are classified as extremely hazardous substances. As the cyanohydrins can readily decompose, and it is hard to find cyanohydrins in gastric contents and heart blood, the determination study in biological samples can be divided into two parts: the first is the determination of HCN by using a Prussian blue reaction and the HS-GC-MSD after derivatization by chloramine-T. The second is the determination of acetone or formaldehyde. In this part, headspace gas chromatography with flame ionization detector (HS-GC-FID) and solid phase microextraction (SPME)-gas chromatography with mass spectrometric detectors (GC-MSD) had been used. In this report, we reported two fatal intoxication cases of ACH and FCH; one person was killed by his wife by poisoning his food and the other was suicide by poison. Two real cases of ACH and FCH in human blood and gastric contents have been analyzed by using the above-mentioned method. The Prussian blue reaction was positive in the two cases. The peaks of acetone with retention times of 0.998 min appear in specimens of the deceased are consistent with the retention times of pure acetone. The peaks of formaldehyde with a retention time of 1.658 min appear in heart blood of the deceased, and the retention time of formaldehyde of the liquid is 1.674 min, which are consistent with the retention times of pure formaldehyde (1.673 min).

    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

    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.

    Alcoholism among minors is a serious social problem. The aim of the current study was to analyze alcohol intoxication in children based on hospitalizations in the University Children's Hospital in Cracow between the years 2007 and 2015. During these 9 years, 381 patients were hospitalized due to excessive alcohol consumption. Most patients were junior high school or high school students. The highest blood alcohol concentrations in hospitalized patients were found in a 16-year-old boy (BAC .41%) and a 15-year-old girl (BAC .37%). Alcohol consumption and severe intoxication are linked to a wide variety of familial, social, and personal problems. PMID:26745242

    2013-09-01

    Acetaminophen or paracetamol, a commonly used over-the-counter analgesic, is known to elicit severe adverse reactions when taken in overdose, chronically at therapeutic dosage or, sporadically, following single assumptions of a therapeutic dose. Damage patterns including liver damage and, rarely, acute tubular necrosis or a fixed drug exanthema. We present a case of fatal acetaminophen toxicity with postmortem blood concentration 78 μg/mL and unusual clinical features, including a visually striking and massive epidermolysis and rhabdomyolysis, disseminated intravascular coagulation and myocardial ischemia. This case is compared with the most similar previous reports in terms of organ damage, clinical presentation, and cause of death. We conclude that a number of severe patterns of adverse effects to acetaminophen are emerging that were previously greatly underestimated, thus questioning the adequacy of the clinical spectrum traditionally associated with acetaminophen intoxication and leading to the need to review this spectrum and the associated diagnostic criteria.

    For a more sensitive detection of paint thinner components in body fluids, we made use of a salting-out technique, with sodium chloride added to blood samples followed by gas chromatography, using the headspace method. The detection of ethyl acetate and isobutanol was considerably enhanced using these approaches. PMID:2303209

    Occupational exposure and sniffing of toluene-based organic solvents is an important public health problem. In this study, we have investigated the effects of paint thinner inhalation on testosterone synthesis and secretion in the male rat. A control group inhaled normal air ventilation. The remaining animals were divided into three groups and exposed to paint thinner in a glassy cage for 15 and 30 days (2 h/day). A group of rats was allowed to recover for 15 days after 30 days of exposure. Toluene concentration (the largest constituent in thinner, 66%) was set at 1500 ppm in the inhaled air. At the end, all animals were decapitated and blood samples obtained. Testes and seminal vesicles were removed and weighed out. Serum total testosterone levels were determined by chemiluminescence enzyme immunoassay. Testicular tissue specimens were processed for semi-quantitative evaluation of immunohistochemical testosterone staining and light microscopy. Intensity of immunostaining was evaluated on a scale between 0 (no staining), 1 (minimal), 2 (mild), 3 (moderate) and 4 (strong staining). Serum testosterone levels (ng/ml) were decreased by 15-day (3.31+/-0.61) and 30-day (1.17+/-0.54, p<0.02) thinner exposure compared to the controls (3.91+/-1.03). Another group of rats exposed to thinner for 30 days and then allowed to recover for a period of 15 days had significantly elevated levels of testosterone values (3.77+/-1.1; p<0.05). Immunohistochemical testosterone staining of the cytoplasm of Leydig cells was moderate (3+) and mild (2+) in 15 and 30 days thinner inhalation groups, respectively. Strong staining (4+) was restored following the recovery period. Testicular weight was significantly reduced in all test groups compared to the control values (p<0.01). Diameters of seminiferous tubules were significantly decreased in the solvent exposed groups with enlarged connective tissue. The present findings suggest that paint thinner inhalation inhibits testosterone synthesis

    2010-01-01

    Background The high risk behavior of intoxicated drivers, impaired reaction time, lack of seat belt use, and increased incidence of head injury raises questions of whether pre-hospital use of alcohol leads to a higher injury severity score and worse clinical outcomes. We therefore compared intoxicated and non-intoxicated drivers of motor vehicle crashes with respect to outcome measurements and also describe the resources utilized to achieve those outcomes at our Level 1 trauma center. Methods Retrospective descriptive study (Jan 2002-June 2007) of our trauma registry and financial database comparing intoxicated drivers with blood alcohol levels (BAC) > 80 mg/dl (ETOH > 80) with drivers who had a BAC of 0 mg/dl (ETOH = 0). Drivers without a BAC drawn or who had levels ranging from 1 mg/dL to 80 mg/dL were excluded. Data was collected on demographic information (age, gender, injury severity score or ISS), outcome variables (mortality, complications, ICU and hospital LOS, ventilator days) and resource utilization (ED LOS, insurance, charges, costs, payments). Statistical analysis: p < 0.05 vs. ETOH > 80; stratified chi square. Results Out of 1732 drivers, the combined study group (n = 987) of 623 ETOH = 0 and 364 ETOH > 80 had a mean age of 38.8 ± 17.9, ISS of 18.0 ± 12.1, and 69.8%% male. There was no difference in ISS (p = 0.67) or complications (p = 0.38). There was a trend towards decreased mortality (p = 0.06). The ETOH = 0 group had more patients with a prolonged ICU LOS (≥ 5 days), ventilator days (≥ 8 days), and hospital LOS (> 14 days) when compared to the ETOH > 80 group (p < 0.05). The ETOH > 80 group tended to be self pay (4.9% vs. 0.7%, p < 0.5) and less likely to generate payment for hospital charges (p < 0.5). Hospital charges and costs were higher in the ETOH = 0 group (p < 0.5). Conclusions The data suggests that intoxicated drivers may have better outcomes and a trend towards reduced mortality. They appeared to be less likely to have prolonged

    This article discusses the case history of an 87-year old woman with loss of consciousness following accidental CO intoxication. A few weeks later, the patient's cognitive abilities progressively deteriorated. This is hence a case of Delayed Neurological Symptoms after CO intoxication. This condition occurs in 40% of patients with CO intoxication and manifests itself 3-240 days after apparent recovery. Symptoms can linger for a long time and are in some cases even permanent. Treatment of CO intoxication usually consists of administering normobaric oxygen and in certain cases hyperbaric oxygen. The role of treatment with hyberbaric oxygen in delayed neurological symptoms after CO intoxication remains controversial, however. PMID:26082431

    Rats were made chronically hyperammonemic by portal-systemic shunting and, 8 wk later, were subjected to acute ammonia intoxication by the intraperitoneal injection of 5.2 mmol/kg of ammonium acetate. In free-ranging animals, ammonia treatment induced a brief period of precoma (10-15 min) that progressed into deep, anesthetic coma lasting for several hours and was associated with a high mortality. In paralyzed, artificially ventilated animals that were lightly anesthetized with nitrous oxide, acute ammonia intoxication caused major disturbances of cerebral carbohydrate, amino acid, and energy metabolism that correlated in time with the change in functional state. At 10 min after injection (precoma), the concentrations of most glycolytic intermediates were increased, as was the lactate/pyruvate ratio. Citrate declined, despite a twofold rise in pyruvate, suggesting that the conversion of pyruvate to citrate had been impaired. Concentrations of phosphocreatine, and of the putative neurotransmitters, glutamate and aspartate, declined during precoma, but the concentrations of the adenine nucleotides in the cerebral hemispheres, cerebellum, and brain stem remained within normal limits. At 60 min after injection (coma), ATP declined in all regions of brain; the reduction in total high-energy phosphates was most notable in the brain stem. The findings indicate that cerebral dysfunction in chronic, relapsing ammonia intoxication is not due to primary energy failure. Rather, it is suggested that ammonia-induced depletion of glutamic and aspartic acids, and inhibition of the malate-asparate hydrogen shuttle are the dominant neurochemical lesions. PMID:838855

    OBJECTIVES: Many establishments serve alcoholic beverages to obviously intoxicated patrons despite laws against such sales. To guide the development of interventions to reduce these illegal alcohol sales, this study used actors feigning intoxication to determine whether servers recognized obvious signs of intoxication and to assess the tactics servers used when dealing with intoxicated patrons. METHODS: Male actors ages 30 to 50 acted out signs of obvious intoxication as they attempted to purchase alcoholic beverages. If served during the first attempt, these pseudo-intoxicated buyers made second purchase attempts during the same visit. Observers accompanied the actors; after each visit, actors and observers recorded the servers' behavior and comments. RESULTS: Alcoholic beverages were served to actors portraying intoxicated patrons at 68% of first purchase attempts and 53% of second purchase attempts (62% of a total of 106 purchase attempts). The most common refusal technique was a direct refusal (68% of refusals), made with either no excuse or with reference to the actors' apparent intoxication level. Servers' second most commonly used refusal technique was offering alcohol-free beverages, such as coffee or water (18% of refusals). CONCLUSIONS: Further research is needed to determine why servers who recognize intoxication serve alcoholic beverages and what training, outlet policies, and external pressures are needed to reduce illegal alcohol sales to obviously intoxicated patrons.

    During the spring of 1981 a massive intoxication broke out in Spain, which is presently attributed to the ingestion of denatured rape oil, and which has been called 'Toxic Syndrome' (TS). We studied 51 patients affected by the TS one year after the onset of their disease, analyzing their vestibular responses in the caloric test with the help of an analog-digital computer. A significant decrease in the number of nystagmic beats of the affected patients can be observed, while the rest of the parameters studied show similar values to those found simultaneously in 30 normal subjects. It is suggested that these differences are yet another manifestation of the polyneuropathy found in intoxication by denatured rape oil. PMID:3877134

    Cocaine is frequently used, especially among adolescents and by men between the age of 25 and 44. Many of them are able to use cocaine in normal day-to-day life, without any problems. Reduced prices of cocaine and other recreational drugs such as MDMA (ecstasy) and gamma hydroxybutyrate (GHB) has led to an increased incidence of intoxications with these drugs. Since the production of cocaine is illegal, it may be impure and mixtures with other drugs such as atropine may occur. The treatment of patients with an acute cocaine intoxication can be complicated. Combination of cocaine with other drugs results in clinical pictures which are difficult to discriminate and that may have important consequences for treatment. PMID:19581655

    Chronic or repeated cocaine use has been linked to impairments in social skills. It is not clear whether cocaine is responsible for this impairment or whether other factors, like polydrug use, distort the observed relation. We aimed to investigate this relation by means of a placebo-controlled experimental study. Additionally, associations between stressor-related activity (cortisol, cardiovascular parameters) induced by the biological stressor cocaine, and potential cocaine effects on emotion recognition were studied. Twenty-four healthy recreational cocaine users participated in this placebo-controlled within-subject study. Participants were tested between 1 and 2 h after treatment with oral cocaine (300 mg) or placebo. Emotion recognition of low and high intensity expressions of basic emotions (fear, anger, disgust, sadness, and happiness) was tested. Findings show that cocaine impaired recognition of negative emotions; this was mediated by the intensity of the presented emotions. When high intensity expressions of Anger and Disgust were shown, performance under influence of cocaine 'normalized' to placebo-like levels while it made identification of Sadness more difficult. The normalization of performance was most notable for participants with the largest cortisol responses in the cocaine condition compared to placebo. It was demonstrated that cocaine impairs recognition of negative emotions, depending on the intensity of emotion expression and cortisol response. PMID:26328908

    Alcohol use disorders (AUD) constitute the most common form of substance abuse. The development of AUD involves repeated alcohol use leading to tolerance, alcohol withdrawal syndrome (AWS), physical and psychological dependence, with loss of ability to control excessive drinking. Currently there is no effective therapeutic agent for AUD without major side-effects. Dihydromyricetin (DHM, 1 mg/kg, i.p. injection), a flavonoid component of herbal medicines, counteracted acute alcohol (EtOH) intoxication, and also withdrawal signs in rats including tolerance, increased anxiety and seizure susceptibility; DHM greatly reduced EtOH consumption in an intermittent voluntary EtOH intake paradigm in rats. GABAA receptors (GABAARs) are major targets of acute and chronic EtOH actions on the brain. At the cellular levels, DHM (1 μM) antagonized both acute EtOH-induced potentiation of GABAARs and EtOH exposure/withdrawal-induced GABAAR plasticity, including alterations in responsiveness of extra- and post-synaptic GABAARs to acute EtOH, and most importantly, increases in GABAAR α4 subunit expression in hippocampus and cultured neurons. DHM anti-alcohol effects on both behavior and CNS neurons were antagonized by flumazenil (10 mg/kg in vivo, 10 μM in vitro), the benzodiazepine (BZ) antagonist. DHM competitively inhibited BZ-site [3H]flunitrazepam binding (IC50, 4.36 μM), suggesting DHM interaction with EtOH involves the BZ-sites on GABAARs. In summary, we determined DHM anti-alcoholic effects on animal models, and determined a major molecular target and cellular mechanism of DHM for counteracting alcohol intoxication and dependence. We demonstrated pharmacological properties of DHM consistent with those expected to underlie successful medical treatment of AUD; therefore DHM is a therapeutic candidate. PMID:22219299

    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

    Some intoxications are more specifically linked to the Aquitaine region than to other regions of France, due to environmental circumstances (fauna, flora, climate) or traditional activities (gastronomy). Three types of intoxications are particular in this area. Pine processionary caterpillar envenomations (Thaumetopoea pityocampa), a Southern Europe pinewood parasite, are frequently encountered in the Landes' forest. They are responsible of ocular and/or skin lesions with urticaria or contact dermatitis, seldom associated with immediate IgE hypersensitivity. According to the south Atlantic coastal region geology and the marine streams, venomous marine animals are mainly located in Charente-Maritime for jellyfish, in Gironde and in Landes for weeverfish and in Atlantic Pyrenees for sea anemone. Usually not dangerous, first-aid workers treat most cases of these envenomations. Some endemic mushrooms (Tricholoma auratum) which grow on the dunes of the Atlantic coastal region, are usually considered as very good comestibles, but were recently responsible for serious intoxications: T.auratum was responsible of several cases of rhabdomyolysis, without neurological involvement, nor renal or hepatic lesion. Three deaths were notified. Animal studies confirmed the responsibility of the mushrooms. PMID:19375827

    Rats were exposed to paint thinner twice a day for a period of 10 minutes on Days 1 through 30 of postnatal life. The subsequent effects upon physical development, swimming ability and escape latency from water were evaluated. Maturation of swimming behavior and general physical development were delayed about 2-4 days in the experimental animals compared with non-exposed littermate controls. The results of these experiments suggest that exposure to this organic solvent during the early postnatal period interferes with the development of the cortico-subcortical neural structures underlying swimming and locomotion.

    Aim To examine the changes in the number of children younger than 18 who were hospitalized due to alcohol intoxication at the Department of Pediatrics, University Hospital of Split, from November 1, 1997 to October 31, 2007. Methods Data on children hospitalized due to intoxication were retrieved from hospital medical records. Children were classified into 4 age groups: 0-5, 6-9, 10-13, and 14-18 years, and their sex and type of intoxication were recorded. For children with alcohol intoxication, data on time of intoxication, reason for drinking, presence of injuries or suspected suicide attempts, and possible presence of other drugs in the organism were collected. Results Out of 29 506 hospitalized children, 594 were hospitalized due to intoxications. Out of these, 239 (40.2%) were hospitalized due to intoxication by alcohol. More boys than girls were hospitalized (71.1%). The proportion of alcohol intoxication cases among all types of intoxication cases increased from 16.7% in 1997/98 to 66.3% in 2006/07. The proportion of patients hospitalized due to alcohol intoxication increased from 0.3% of all hospitalized children in the first year to 1.7% in the last year of the study (P = 0.015, z test for comparison of two proportions). Eighty two per cent of cases of alcohol intoxication were in the 14-18 age-group. The number of alcohol intoxication cases increased among girls from 1 case (6.3% of all intoxication cases among girls) in 1997/98 to 15 cases (45.5%) in 2006/07, while among boys it increased from 6 cases (23.1% of all intoxicated boys) in 1997/98 to 44 cases (78.6%) in 2006/07. Children usually drank outside their homes (79.4%) and mostly on weekends and holidays (73.2%). Conclusion The alarming increase in the number of hospitalizations due to alcohol intoxication in children, especially among girls and in the adolescent age group, represents a serious problem, which requires further attention and research.

    Reports of acute arsenic poisoning arising from environmental exposure are rare. Two cases of acute arsenic intoxication resulting from ingestion of contaminated well water are described. These patients experienced a variety of problems: acute gastrointestinal symptoms, central and peripheral neurotoxicity, bone marrow suppression, hepatic toxicity, and mild mucous membrane and cutaneous changes. Although located adjacent to an abandoned mine, the well water had been tested for microorganisms only and was found to be safe. Regulations for testing of water from private wells for fitness to drink are frequently nonexistent, or only mandate biologic tests for microorganisms. Well water, particularly in areas near mining activity, should be tested for metals.

    Background Alcohol intoxication can increase inflammation and worsen injury, yet the mechanisms involved are not clear. We investigated whether acute alcohol intoxication elevates microvascular permeability, and investigated potential signaling mechanisms in endothelial cells that may be involved. Methods Conscious rats received a 2.5 g/kg alcohol bolus via gastric catheters to produce acute intoxication. Microvascular leakage of intravenously administered FITC-albumin from the mesenteric microcirculation was assessed by intravital microscopy. Endothelial-specific mechanisms were studied using cultured endothelial cell monolayers. Transendothelial electrical resistance (TER) served as an index of barrier function, before and after treatment with alcohol or its metabolite acetaldehyde. Pharmacologic agents were used to test the roles of alcohol metabolism, oxidative stress, p38 mitogen-activated protein (MAP) kinase, myosin light chain kinase (MLCK), rho kinase (ROCK), and exchange protein activated by cAMP (Epac). VE-cadherin localization was investigated to assess junctional integrity. Rac1 and RhoA activation were assessed by ELISA assays. Results Alcohol significantly increased FITC-albumin extravasation from the mesenteric microcirculation. Alcohol also significantly decreased TER and disrupted VE-cadherin organization at junctions. Acetaldehyde significantly decreased TER, but inhibition of ADH or application of a superoxide dismutase mimetic failed to prevent alcohol-induced decreases in TER. Inhibition of p38 MAP kinase, but not MLCK or ROCK, significantly attenuated the alcohol-induced barrier dysfunction. Alcohol rapidly decreased GTP-bound Rac1 but not RhoA during the drop in TER. Activation of Epac increased TER, but did not prevent alcohol from decreasing TER. However, activation of Epac after initiation of alcohol-induced barrier dysfunction quickly resolved TER to baseline levels. Conclusions Our results suggest that alcohol intoxication increases

  16. Approach to the Treatment of Methanol Intoxication.

    PubMed

    Kraut, Jeffrey A

    2016-07-01

    Methanol intoxication is an uncommon but serious poisoning. Its adverse effects are due primarily to the impact of its major metabolite formic acid and lactic acid resulting from cellular hypoxia. Symptoms including abdominal pain and loss of vision can appear a few hours to a few days after exposure, reflecting the time necessary for accumulation of the toxic byproducts. In addition to a history of exposure, increases in serum osmolal and anion gaps can be clues to its presence. However, increments in both parameters can be absent depending on the nature of the toxic alcohol, time of exposure, and coingestion of ethanol. Definitive diagnosis requires measurement with gas or liquid chromatography, which are laborious and expensive procedures. Tests under study to detect methanol or its metabolite formate might facilitate the diagnosis of this poisoning. Treatment can include administration of ethanol or fomepizole, both inhibitors of the enzyme alcohol dehydrogenase to prevent formation of its metabolites, and hemodialysis to remove methanol and formate. In this Acid-Base and Electrolyte Teaching Case, a patient with methanol intoxication due to ingestion of model airplane fuel is described, and the value and limitations of current and new diagnostic and treatment measures are discussed.

    During the autumn of 1989 a feed contamination induced a widespread lead intoxication of cattle in the northern provinces of The Netherlands (Groningen and Friesland). Over 300 farms were involved, affecting about 15,500 animals (mostly dairy cattle). For a period of one to four weeks these animals took up a thousand kg of lead. This resulted in lead levels in milk, livers, and kidneys above the regulatory safety limits. Due to the chelating therapy, which was rapidly applied by the local veterinarians, only about 30 animals died of an acute lead intoxication. A joint action of the governmental and private authorities prevented exposure of consumers to lead-contaminated animal products. Based on observations, measurements and literature data, predictions were made of the lead levels to be expected in animal products and the time needed for depletion of these levels. The appropriate animals were ear-tagged to ensure their identification, and the decline in time of the lead levels in milk and offals was conscientiously monitored. In the second week of 1990 the lead concentrations were decreased to levels well below the regulatory limits, and hence the tags were removed. The present paper reports our observations and conclusions, especially regarding treatment, predictions and outcome of this incident. PMID:1493885

    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

    Fentanyl (N-phenyl-N-(1-2-phenylethyl-4-piperidyl)propanamide) is a potent synthetic narcotic analgesic. He has an analgesic effect 100 times greater than that of morphine. The use of transdermal fentanyl delivrery systems has increased over recent years especially in patients with chronic pain who are already treated with high doses of morphine or it is derivate. However, many cases of fentanyl intoxication through a variety of transderrmal systems have been reported. This paper reports a fatality due to excessive administered Fentanyl Sandoz® Matrix 50µg/h transdermal therapeutic systems. PMID:26015841

    1998-11-01

    The effects of ingesting ethanol have been shown to be somewhat variable in humans; there appear to be but few universals. Yet, questions about intoxication often are asked by law enforcement personnel (especially relative to DUI), clinicians and various individuals in social settings. A key question: Is it possible to determine if a person is intoxicated by observing them in some manner? A closely associated one: Can speech be used for that purpose? Two of the many issues related to the second of these questions involve the possibility that (1) speakers, especially actors, can effectively mimic the speech of intoxicated individuals, and (2) they may be able to volitionally reduce any speech degradation which results from intoxication. The approach used to test these two questions tasked auditors to determine if these simulations were possible. To this end, young, healthy actors chosen on the basis of a large number of selection criteria were asked to produce several types of controlled utterances (1) during a learning phase, (2) when sober, (3) at three simulated levels of intoxication (mildly, legally and severely drunk), (4) during actual, and parallel, levels of intoxication, and (5) at the highest intoxication level attained but when attempting to sound completely sober. Two aural-perceptual studies were conducted; both involved counterbalanced ABX procedures where each subject was paired with him/herself. Listeners were normally hearing university students drawn from undergraduate phonetics and linguistics courses. In the first study, they rated the actors as being more intoxicated--when they actually were sober but simulating drunkenness--88% more often than when they actually were intoxicated. In the second study, they were judged as sounding less inebriated when attempting to sound sober (than they actually were) 61% of the time. These relationships would appear to impact a number of situations; one of special importance would be the detection of

    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 have investigated the effects of thinner inhalation on serum LH, FSH and testosterone levels together with changes in hypothalamic catecholaminergic system in the male rat. A control group inhaled normal air ventilation. The remaining animals were divided into two groups and exposed to paint thinner in a glassy cage for 15 or 30 d. Toluene concentration (the largest constituent in thinner, 66%) was set at 3000 ppm in the inhalation air. At the end, all animals were decapitated and blood samples obtained. Serum LH and FSH levels were measured by RIA and testosterone by enzyme immunoassay. Following removal of brains on dry ice, medial preoptic area, suprachiasmatic nucleus, median eminence and arcuate nucleus were isolated by micropunch technique. Noradrenaline, 3,4-dihydroxyphenylglycol (DHPG) and dopamine concentrations of these hypothalamic areas were determined by HPLC-ECD. Fifteen-day thinner inhalation significantly suppressed serum LH and testosterone levels in parallel (p<0.001) compared to control group values (LH: 0.77+/-0.07; testosterone: 2.67+/-0.39). Thirty-day exposure markedly decreased LH levels (p<0.001), but surprisingly had no significant effect on testosterone. Serum FSH levels were not significantly altered in either group. Thinner inhalation for 15 or 30 d did not cause any significant change in noradrenaline, DHPG or dopamine concentrations in the hypothalamic regions examined (except in the arcuate nucleus). These results suggest that paint thinner has an anti-gonadotropic effect and may cause long-term endocrine disturbances in the male. It is thought that the hypothalamic catecholaminergic system is not involved in thinner inhibition of LH and testosterone secretion. PMID:11217085

    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.

    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. PMID:20118865

    The courts have implemented numerous approaches to reduce the probability of recidivism among people apprehended for or convicted of driving while intoxicated. Although traditional punitive sanctions, such as fines and incarceration, are commonly used, they have not eliminated drinking and driving in the United States. Consequently, the court system has developed additional sanctioning procedures that show promise. For example, rehabilitative programs (e.g., alcohol education and alcoholism treatment) can reduce recidivism, at least marginally. These programs appear to be more effective when combined with license suspension. In addition to license suspension, several alternative methods for limiting driving opportunities of offenders have proven effective, including impounding offenders' vehicles or license plates, installing ignition interlocks, and requiring electronic home monitoring or house arrest. Effective court monitoring is a critical component in supporting recovery and compelling offenders to participate in rehabilitation programs. This role of the courts in monitoring offenders will likely increase as the use of intrusive, alternative sanctions grows. PMID:11496964

    Many trauma patients are acutely intoxicated with alcohol. Animal studies have demonstrated that acute alcohol intoxication inhibits the normal release of epinephrine, norepinephrine, and vasopressin in response to acute hemorrhage. Ethanol also increases nitric oxide release and inhibits antidiuretic hormone secretion. This article studies the effects of alcohol intoxication (measured by blood alcohol level, BAL) on the presentation and resuscitation of trauma patients with blunt hepatic injuries. A retrospective registry and chart review was conducted of all patients who presented with blunt liver injuries at an ACS-verified, level I trauma center. Data collected included admission BAL, systolic blood pressure, hematocrit, International Normalized Ratio (INR), liver injury grade, Injury Severity Score (ISS), intravenous fluid and blood product requirements, base deficit, and mortality. From September 2002 to May 2008, 723 patients were admitted with blunt hepatic injuries. Admission BAL was obtained in 569 patients, with 149 having levels >0.08%. Intoxicated patients were more likely to be hypotensive on admission (p = 0.01) despite a lower liver injury grade and no significant difference in ISS. There was no significant difference in the percent of intoxicated patients requiring blood transfusion. However, when blood was given, intoxicated patients required significantly more units of packed red blood cells (PRBC) than their nonintoxicated counterparts (p = 0.01). Intoxicated patients also required more intravenous fluid during their resuscitation (p = 0.002). Alcohol intoxication may impair the ability of blunt trauma patients to compensate for acute blood loss, making them more likely to be hypotensive on admission and increasing their PRBC and intravenous fluid requirements. All trauma patients should have BAL drawn upon admission and their resuscitation should be performed with an understanding of the physiologic alterations associated with acute alcohol

    Children with fetal alcohol spectrum disorders (FASD) may exhibit craniofacial dysmorphology, neurobehavioral deficits, and reduced brain volume. Studies of cortical thickness in FASD have yielded contradictory findings, with 3 reporting thicker cerebral cortex in frontal and temporal brain regions and 2 showing thinner cortex across multiple regions. All 5 studies included subjects spanning a broad age range, and none have examined continuous measures of prenatal alcohol exposure. We investigated the relation of extent of in utero alcohol exposure to cortical thickness in 78 preadolescent children with FASD and controls within a narrow age range. A whole-brain analysis using FreeSurfer revealed no significant clusters where cortical thickness differed by FASD diagnostic group. However, alcohol dose/occasion during pregnancy was inversely related to cortical thickness in 3 regions-right cuneus/pericalcarine/superior parietal lobe, fusiform/lingual gyrus, and supramarginal/postcentral gyrus. The effect of prenatal alcohol exposure on IQ was mediated by cortical thickness in the right occipitotemporal region. It is noteworthy that a continuous measure of maternal alcohol consumption during pregnancy was more sensitive than FASD diagnosis and that the effect on cortical thickness was most evident in relation to a measure of maternal binge drinking.

  9. Building a Thinner Gap in a Gas-Gap Heat Switch

    Franco, J.; Galinhas, B.; Sousa, P. Borges de; Martins, D.; Catarino, I.; Bonfait, G.

    A gas-gap heat switch (GGHS) reaches its highest conductance state when the gap between two exchange surfaces is filled with a conducting gas in a viscous regime. The broader the surface and the thinner the gap, the higher the ON conductance achieved. In this paper we describe a very thin cold gas-gap heat switchreached upon the use of the differential thermal expansion of the construction materials. Such technique overcomes the intricacies of the manufacturing process of the switch. We designed built and tested a prototype of a very thin gap heat switch using our new methodology. The high conductance was measured with both helium and nitrogen, at temperatures ranging from 20 K (He) or 75 K (N2) up to room temperature. The inferred gap opening at low temperature (≈ 17 μm) has shown to be slightly above the expected, which allowed us to reinterpret the design calculations. The switch was also characterized along its extreme conductance states while using a sorption pump, and its performance was compared with a previously developed model. Lessons learned from the first prototype led us to build a second one with better performance. Our experiments suggest that the proposed design allows for the development of a customized cryogenic switch with improved ON conductance while keeping the assembly very simple and sturdy, hence widening the scope of applicability of these devices.

    We present three fatal intoxications of methylone, a cathinone derivative. Blood was analyzed with a routine alkaline liquid-liquid extraction and analyzed by gas chromatography coupled with a mass spectrometer (GC-MS). Methylone was identified by a full scan mass spectral comparison to an analytical standard of methylone. For a definitive and conclusive confirmation and quantitation, methylone was also derivatized with heptafluorobutyric anhydride and analyzed by GC-MS. In all three fatalities, the deceased exhibited seizure-like activity and elevated body temperatures (103.9, 105.9 and 107°F) before death. Two of the three cases also exhibited metabolic acidosis. One of the three cases had prolonged treatment and hospitalization before death with symptoms similar to sympathomimetic toxicity, including metabolic acidosis, rhabdomyolysis, acute renal failure and disseminated intravascular coagulation. The laboratory results for this patient over the 24 h period of hospitalization were significant for increased lactate, liver transaminases, creatinine, myoglobin, creatine kinase and clotting times, and decreased pH, glucose and calcium. Peripheral blood methylone concentrations in the three fatal cases were 0.84, 3.3 and 0.56 mg/L. In conlusion, peripheral blood methylone concentrations in excess of 0.5 mg/L may result in death due to its toxic properties, which can include elevated body temperature and other sympathomimetic-like symptoms.

    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.

    The symptoms of MDA intoxication exhibited by the decedent prior to death closely mimic those of acute amphetamine poisoning: profuse sweating, violent and irrational behavior, and stereotypically compulsive behavior. Therefore, if amphetamines are not detected in specimens from a person displaying classic symptoms of amphetamine poisoning, hallucinogenic amphetamine derivatives may be considered. In the case described, a divided dose of 850 mg of MDA ingested within 2 h and 15 min was sufficient to cause the death of a 24-year-old male, 4 h after the final dose. While the methaqualone may have contributed to the demise of the decedent, the authors think that the MDA itself was sufficient to cause death. Results of limited recovery studies of MDA extraction from blood and elution from TLC plates supported the observations of Cimbura [13]. Approximately 85% of MDA is extracted by the method described and its elution from TLC plates is quantitative. This case points out once again the dangers of false advertising in the illicit market. The decedent, himself a dealer in the illicit drug market, and all present at the party believed the ingested white powder to be a mixture of morphine, LSD, and amphetamine, hence MDA. They were totally unfamiliar with 3,4-methylenedioxyamphetamine, MDA. PMID:512617

    Of 1,994 yearling and 2-year-old cattle in a winter feeding program, 117 died within 42 days of being fed toxic amounts of monensin sodium in a liquid protein supplement. Death losses commenced on the third day after ingestion of a toxic amount in the feed. Clinical signs in cattle that died in less than 9 days included anorexia, pica, diarrhea, depression, mild hindlimb ataxia, and dyspnea. Gross necropsy findings in cattle dying in the acute phase of the illness included hydrothorax, ascites, and pulmonary edema, as well as petechial hemorrhages, edema, and yellow streaking in skeletal and cardiac muscle. Cattle dying after 9 days had gray streaks in heart and skeletal muscle, generalized ventral edema, enlarged, firm, bluish discolored liver, and enlarged heart. Microscopic changes in cattle dying in the acute phase (less than 9 days) consisted of pulmonary edema, congestion, and hemorrhage. Cardiac and skeletal muscle had localized areas of edema, hemorrhage, and coagulative necrosis. In cattle dying after 9 days of illness, the changes included lymphocytic infiltration, sarcolemmal nuclear proliferation, and fibrosis in skeletal and cardiac muscle. Lungs contained increased alveolar macrophages and a few neutrophils. Centrilobular necrosis and mild fibrosis were found in the liver. Changes varied somewhat according to the area of heart or skeletal muscle that was affected. Active muscles, eg, those in the heart ventricles and diaphragm, were altered most severely. Intoxication appeared to be a result of sedimentation of monensin in the molasses carrier to give remarkable concentrations of the substance at the bottom of the holding tank. PMID:6735846

    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

    A comparative study on the effect of oral and subcutaneous (sc) or intravenous (iv) administration of S-adenosyl-L-methionine (SAM) in lead poisoning was carried out. SAM was given daily sc (20 mg/kg) and orally (80 mg/kg) to acute lead-intoxicated mice for 20 days. Chronic lead-poisoned patients received SAM, administered intravenously at a daily dose of 12 mg/kg or orally at a dose of 25-30 mg/kg. Independent of the method of administration in either animals or patients, GSH concentration in reduced lead intoxication was increased after SAM dosing. Corresponding blood lead content rapidly decreased and a significant recovery of hepatic and erythrocytic delta-aminolevulinate dehydratase (ALA-D), initially reduced, was clearly produced in the groups receiving SAM, although the response was slightly slower when SAM was given orally. It was found that the bulk of body lead burden was excreted in the feces, showing a peak within the first 24-48 hr and being much greater in animals treated with SAM. In these cases, urinary lead excretion was very low. Lead ALA-D inhibition was also evidenced by elevated urinary excretion of delta-aminolevulinic acid (ALA), porphobilinogen (PBG), and porphyrins. During treatment, precursors and porphyrins elimination declined, reaching normal levels soon after therapy ended. A good correlation between the recovery of both GSH levels and ALA-D activity and decreased lead content was observed.

    Neurologic and psychiatric symptoms such as headache, tinnitus, defective hearing, changing desorientation and aggressiveness are initial symptoms of methyltin chloride intoxication. Some patients also developed epileptic equivalents, such as dreamy attacks and central ventilation transaminases. 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.

    Tetramethylenedisulfotetramine (TETS) is a potent convulsant poison that is thought to trigger seizures by inhibiting the function of the type A gamma-aminobutyric acid receptor (GABAAR). Acute intoxication with TETS can cause vomiting, convulsions, status epilepticus (SE) and even death. Clinical case reports indicate that individuals who survive poisoning may exhibit long-term neuropsychological issues and cognitive deficits. Therefore, the objective of this research was to determine whether a recently described mouse model of acute TETS intoxication exhibits persistent behavioral deficits. Young adult male NIH Swiss mice received a seizure-inducing dose of TETS (0.15mg/kg, ip) and then were rescued from lethality by administration of diazepam (5mg/kg, ip) approximately 20min post-TETS-exposure. TETS-intoxicated mice typically exhibited 2 clonic seizures prior to administration of diazepam with no subsequent seizures post-diazepam injection as assessed using behavioral criteria. Seizures lasted an average of 72s. Locomotor activity, anxiety-like and depression-relevant behaviors and cognition were assessed at 1week, 1month and 2months post-TETS exposure using open field, elevated-plus maze, light↔dark transitions, tail suspension, forced swim and novel object recognition tasks. Interestingly, preliminary validation tests indicated that NIH Swiss mice do not respond to the shock in fear conditioning tasks. Subsequent evaluation of hot plate and tail flick nociception tasks revealed that this strain exhibits significantly decreased pain sensitivity relative to age- and sex-matched C57BL/6J mice, which displayed normal contextual fear conditioning. NIH Swiss mice acutely intoxicated with TETS exhibited no significant anxiety-related, depression-relevant, learning or memory deficits relative to vehicle controls at any of the time points assessed with the exception of significantly increased locomotor activity at 2months post-TETS intoxication.

    Extracorporeal modalities for the removal of drugs and toxins are indicated for the treatment of overdoses and intoxications. Well-established modalities include hemodialysis (HD), high-flux HD (HfD), and charcoal hemoperfusion (HP). Recently, there have been increasing reports on the use of continuous renal replacement therapy (CRRT), such as continuous veno-venous hemodialysis (CVVHD), continuous veno-venous hemofiltration (CVVH) or CVVH combined with dialysis (CVVHDF). In the present article, we will discuss the various factors that determine the clearance of drugs and toxins and accordingly, we will propose that with few exceptions, CRRT does not have a role in the routine management of intoxications.

    Abstract While carbon monoxide (CO) intoxication often triggers multiple intraneuronal immune- or inflammatory-related cascades, it is not known whether the pathological processes within the affected regions evolve equally in the long term. To understand the neurodegenerative networks, we examined 49 patients with a clinical diagnosis of CO intoxication related to charcoal burning suicide at the chronic stage and compared them with 15 age- and sex-matched controls. Reconstructions of degenerative networks were performed using T1 magnetic resonance imaging, diffusion-tensor imaging, and fluorodeoxyglucose positron emission tomography (PET). Tract-specific fractional anisotropy (FA) quantification of 11 association fibers was performed while the clinical significance of the reconstructed structural or functional networks was determined by correlating them with the cognitive parameters. Compared with the controls, the patients had frontotemporal gray matter (GM) atrophy, diffuse white matter (WM) FA decrement, and axial diffusivity (AD) increment. The patients were further stratified into 3 groups based on the cognitive severities. The spatial extents within the frontal-insular-caudate GM as well as the prefrontal WM AD increment regions determined the cognitive severities among 3 groups. Meanwhile, the prefrontal WM FA values and PET signals also correlated significantly with the patient's Mini-Mental State Examination score. Frontal hypometabolic patterns in PET analysis, even after adjusted for GM volume, were highly coherent to the GM atrophic regions, suggesting structural basis of functional alterations. Among the calculated major association bundles, only the anterior thalamic radiation FA values correlated significantly with all chosen cognitive scores. Our findings suggest that fronto-insular-caudate areas represent target degenerative network in CO intoxication. The topography that occurred at a cognitive severity-specific level at the chronic phase

    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

    Different brain sections were studied in 20 subjects, who died of ethanol intoxication and in 14 subjects who died of injuries of the heart and main vessels, in order to detect histological changes in the brain and for the purpose of defining spatial and quantitative ratios between cerebral tissue structures in alcoholic intoxication. Different histological, stereometric and morphometric tools were made use of. It was demonstrated that, in alcoholic intoxication, there occur severe disorders of the circulation with affection of vessels in the brain; there are also dystrophic and necrotic changes in neurocytes, glial cells and white substance. The square of neurons shrinks due to death of some of them in the cortex of hemispheres, thalamus and cerebellum. As for the medulla, they are more resistant, there, to ethanol. The diameter of capillaries in the studied brain sections diminishes due to a reduced tonus of cerebral arteries; the quantity of such vessels increases within a standard area, which is conditioned by the compensatory opening of reserve capillaries. All this can be important in dealing with issues of thanatogenesis and of forensic medical diagnosis in death of alcoholic intoxication. PMID:15881135

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

    2013-01-01

    This literature review is focused on diagnostics of acute clozapine intoxication with the fatal outcome. According to the Russian authors, clozapine intoxication ranks first in the structure of criminal poisoning and accounted for 99.7% of all the cases that occurred in Moscow during the period from 2003 to 2006. Toximetric investigations of clinical manifestations of clozapine intoxication revealed that the threshold clozapine concentration in blood is 0.12 ± 0.06 mg/I, the critical and lethal concentrations are 1.01 ± 0.2 mg/I and 3.5 ± 1.5 mg/I respectively. Autopsy on corpses of the victims of clozapine intoxication showed that most clozapine-induced pathological changes have a non-specific character (including largely circulatory disorders and dystrophic changes in parenchymatous organs). Clozapine poisoning is associated with the lengthening of QT-interval on ECG; at the values in excess of 500 ms, the risk of severe arrhythmia and sudden death significantly increases. Clozapine intake may lead to the development of potentially fatal myocarditis (the so-called clozapine-associated eosinophilic myocardium) in somatically healthy subjects. Foreign researchers report the possibility of a post-mortem increase of blood clozapine content compared with its antemortem level. They also showed that simultaneous use of substances stimulating activity of cytochrome P-450 enzymes (ethyl alcohol, finlepsin, fenitrin, nicotine) and clozapine accelerates metabolism and thereby reduces clozapine concentration in blood. It is concluded that comprehensive investigations of clozapine intoxication are needed taking into consideration pathomorphological changes induced by this agent, its potential interaction with other factors influencing human body, and the results of forensic chemical expertise of the fatal cases.

    2015-01-01

    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

    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.

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.

    Abstract Acetaminophen (APAP) intoxication is a common cause of hepatic toxicity and life-threatening hepatic failure. However, few studies have investigated the possible association between APAP intoxication and acute kidney injury (AKI). We constructed a retrospective cohort study to clarify the relationship between APAP intoxication and the risk of AKI. We identified patients with APAP intoxication and selected a comparison cohort that was 1:4 frequency matched according to age, sex, and year of APAP intoxication diagnosis from the Taiwan National Health Insurance Research Database from 1998 to 2010. We analyzed the risks of AKI for patients with APAP intoxication by using Cox proportional hazards regression models. In this study, 2914 patients with APAP intoxication and 11,656 controls were included. The overall risks of developing AKI were 2.41-fold in the patients with APAP intoxication compared with the comparison cohort. After we excluded APAP intoxication patients with coexisting AKI and hepatic failure/hepatitis, the overall risks of developing AKI were still 2.22-fold in the patients with APAP intoxication. There were 2 patients who had end-stage renal disease (ESRD) following APAP intoxication-related AKI. Limitations include retrospective review, selection bias, and absence of data on detail medications used, laboratory investigations and dosage of APAP intoxication. Our long-term cohort study results showed that AKI is a possible adverse effect among patients with APAP intoxication, regardless of whether patients have presented with hepatic toxicity. However, additional studies are necessary to clarify whether such patients can progress to ESRD. PMID:26579812

    We report a case of a 37-year-old woman with non-insulin-dependent diabetes on sitagliptin, an alcohol abuser who was brought unresponsive to the emergency department of our hospital. On arrival, the patient was intubated and mechanically ventilated due to a low Glasgow Coma score of 3/15. Initial laboratory testing identified profound high anion gap metabolic acidosis. Owing to the dubious circumstances and the depth of acidosis, methanol and ethylene glycol intoxication was suspected. Further evaluation revealed a significantly increased serum osmolal gap. Pending volatile compound screen, fomepizole was started and urgent haemodialysis undertaken. Subsequent brain MRI identified changes in putamen of bilateral basal ganglia, suggestive of methanol intoxication. The patient was later found to have an initial methanol level of 237 mg/dL. She was successfully extubated on day 2 of hospitalisation, with residual cognitive and visual deficits. PMID:26917798

    A variety of plants and seeds, some of which are used for therapeutic and nutritional purposes, can cause neurotoxic symptoms. The ingestion of the green or ripe fruit of the Karwinskia humboldtiana (buckthorn), a bush known in Mexico as coyotillo or tullidora, causes a flaccid, symmetric, progressive, and ascending palsy of the lower limbs, which, in severe cases, can cause bulbar palsy and death. The neurologic symptoms are similar to those of poliomyelitis, Guillain-Barré syndrome, and other polyradiculoneuritis syndromes, for which it is often mistaken. The clinical diagnosis of intoxicated patients can be difficult without a history of the fruit ingestion. We present a report of three siblings with buckthorn intoxication. PMID:17378625

    Manganese (Mn) intoxication is associated with neurological dysfunctions collectively known as Parkinsonism or Manganism. Like in Parkinson's disease, Manganism is associated with motor disturbances, together with non-motor symptoms including cognitive and neuropsychiatric deficits. Although sleep dysfunctions are commonly reported among workers exposed to Mn, their underlying pathophysiology remains unknown. In this study, we investigated the rest-activity rhythms in rats treated daily with MnCl2 (10mg/kg, i.p) for 5weeks. Locomotor activity was assessed under a light-dark (LD) cycle, constant darkness (DD) and during adjustment to 6h shifts of the LD cycle. In LD conditions, Mn-treated rats exhibited a more fragmented and less stable rest-activity rhythm in addition to a reduction in the total 24-h amount of locomotor activity as well as in the activity confined to the active dark phase of the LD. Consequently, a significant decrease in the amplitude of the rest-activity rhythm was observed. These disturbances were displayed during and after Mn treatment. Furthermore, after the 6-h phase advance of the LD cycle, Mn-treated rats failed to re-adjust accurately their behavioral activity to the new shifted LD cycle. Upon release from LD into DD, Mn-treated rats expressed a normal and stable free-running period of their rest-activity rhythm (23.92±0.07h in Mn group vs. 24.01±0.04h in control rats). However, their rest-activity rhythm remained highly fragmented and less stable. Our results provide the first evidence that chronic Mn intoxication leads to impairment of rest-activity rhythms in addition to the motor and non-motor disturbances reported in Manganism.

    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.
