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

  3. Oral cadmium chloride intoxication in mice

    Andersen, O; Nielsen, J B; Svendsen, P

    1988-01-01

    Diethyldithiocarbamate (DDC) is known to alleviate acute toxicity due to injection of cadmium salts. However, when cadmium chloride was administered by the oral route, DDC enhanced rather than alleviated the acute toxicity; both oral and intraperitoneal (i.p.) administration of DDC had this effect...

  4. Lead intoxication under environmental hypoxia impairs oral health.

    We have reported that chronic lead intoxication under hypoxic environment induces alveolar bone loss that can lead to periodontal damage with the subsequent loss of teeth. The aim of the present study was to assess the modification of oral inflammatory parameters involved in the pathogenesis of periodontitis in the same experimental model. In gingival tissue, hypoxia increased inducible nitric oxid synthase (iNOS) activity (p lead decreased prostaglandin E2 (PGE2) content (p lead and PGE2 content was increased by both lead and hypoxia (p lead under hypoxic conditions. Results suggest a wide participation of inflammatory markers that mediate alveolar bone loss induced by these environmental conditions. The lack of information regarding oral health in lead-contaminated populations that coexist with hypoxia induced us to evaluate the alteration of inflammatory parameters in rat oral tissues to elucidate the link between periodontal damage and these environmental conditions.

  5. Ulcerative colitis patients with an inflammatory response upon mesalazine cannot be desensitized: a randomized study.

    2015-04-01

    Mesalazine is a key drug in the treatment of ulcerative colitis (UC). Intolerance to mesalazine has been described, including fever and gastrointestinal symptoms. Several case reports reported successful desensitization of patients with mesalazine intolerance. The aim was to assess the number of UC patients who are persistently intolerant to mesalazine after single-blinded rechallenge and to test the effectiveness of a rapid desensitization protocol in UC patients demonstrated mesalazine intolerance. This is a prospective, single-blind randomized study in UC patients who discontinued mesalazine because of intolerance. Patients with severe reactions were excluded. Eligible patients underwent a skin patch test with mesalazine followed by a single-blinded randomized crossover rechallenge with 500 mg mesalazine or placebo. Patients with symptoms upon rechallenge were admitted to the hospital for 3 days oral desensitization. Nine of the 37 identified UC patients who discontinued mesalazine because of intolerance were included. All nine patients had negative patch tests, seven patients had symptoms (fever, nausea, vomiting and diarrhea) within 2 h upon rechallenge. Four of these seven patients participated in the desensitization protocol and in none a successful desensitization could be performed. All four had an inflammatory intolerance reaction with rise in C-reactive protein. There were no elevations in serum tryptase or urinary-methylhistamine levels observed and no signs of immediate type allergic reactions, like urticaria, bronchial obstruction or anaphylaxis. We recommend not to rechallenge UC patients with an inflammatory response upon mesalazine and these patients will not benefit from a rapid desensitization protocol.

  6. Oral cadmium chloride intoxication in mice: Effects of penicillamine, dimercaptosuccinic acid and related compounds

    Andersen, O.; Nielsen, J.B.

    1988-01-01

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

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

  8. Inhibiting oral intoxication of botulinum neurotoxin A by carbohydrate receptor mimics

    Botulinum neurotoxins (BoNTs) cause the disease botulism manifested by flaccid paralysis that could be fatal to humans and animals. Oral ingestion of the toxin with contaminated food is one of the most common routes of BoNT intoxication, where BoNT assembles with several auxiliary proteins to surviv...

  9. The effect of oral castor oil on the disposition of methyprylon in intoxicated dogs.

    Gwilt, P R; Pankaskie, M C; Mitala, J J

    1982-07-01

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

    The goal was to make available a delayed-release dosage form of mesalazine to be dispersed in water to facilitate swallowing in adults and children. Mesalazine microparticles containing carnauba wax were prepared by spray-congealing technique. A second step of spray-congealing of carnauba microparticles dispersed in liquefied stearic acid gave rise to mesalazine lipid microcapsules in which several carnauba microparticles remained embedded as cores in a reservoir structure. In order to favor their water dispersion, the lipid microcapsules were dry coated by tumbling them with different ratios of mannitol/lecithin microparticles prepared by spray-drying. Release rate measurements showed a delayed-release behavior, in particular a pH-dependence with less than 10% of drug released in acidic medium and complete release in phosphate buffer pH 7.4 in 4-5h. The layering with hydrophilic excipient microparticles allowed manufacturing of a pH-dependent dosage form suitable for extemporaneous oral use in adults and children. Copyright © 2011 Elsevier B.V.

    Low-grade intestinal inflammation plays a role in the pathophysiology of IBS. In this trial, we aimed at evaluating the efficacy and safety of mesalazine in patients with IBS. We conducted a phase 3, multicentre, tertiary setting, randomised, double-blind, placebo-controlled trial in patients with Rome III confirmed IBS. Patients were randomly assigned to either mesalazine, 800 mg, or placebo, three times daily for 12 weeks, and were followed for additional 12 weeks. The primary efficacy endpoint was satisfactory relief of abdominal pain/discomfort for at least half of the weeks of the treatment period. The key secondary endpoint was satisfactory relief of overall IBS symptoms. Supportive analyses were also performed classifying as responders patients with a percentage of affirmative answers of at least 75% or >75% of time. A total of 185 patients with IBS were enrolled from 21 centres. For the primary endpoint, the responder patients were 68.6% in the mesalazine group versus 67.4% in the placebo group (p=0.870; 95% CI -12.8 to 15.1). In explorative analyses, with the 75% rule or >75% rule, the percentage of responders was greater in the mesalazine group with a difference over placebo of 11.6% (p=0.115; 95% CI -2.7% to 26.0%) and 5.9% (p=0.404; 95% CI -7.8% to 19.4%), respectively, although these differences were not significant. For the key secondary endpoint, overall symptoms improved in the mesalazine group and reached a significant difference of 15.1% versus placebo (p=0.032; 95% CI 1.5% to 28.7%) with the >75% rule. Mesalazine treatment was not superior than placebo on the study primary endpoint. However, a subgroup of patients with IBS showed a sustained therapy response and benefits from a mesalazine therapy.

  12. Intoxication after Extreme Oral Overdose of Quetiapine to Attempt Suicide: Pharmacological Concerns of Side Effects

    C. Müller

    2009-01-01

    Full Text Available Quetiapine is an atypical antipsychotic approved for the treatment of patients with psychotic disorders. Since approvement several case reports about intoxication with quetiapine were linked mainly with tachycardia, QTc-prolongation, somnolence, and hyperglycemia. Here, we present the first case report of an intoxication with an extreme overdose of quetiapine (36 g, ingested by a 32-year-old female (62 kg bodyweight to attempt suicide. Symptoms associated with intoxication were coma without arterial hypotension, persistent tachycardia, hyperglycemia, and transient hypothyreoidism. QTc-interval was moderately extended. Management consisted of intubation for airway protection, gastric lavage, the use of activated charcoal, i.v. saline, and observation for 17 hours on an intensive care unit. Despite the extremely high dose of quetiapine, the patient recovered completely without residual symptoms.

  13. A plant-based oral vaccine to protect against systemic intoxication by Shiga toxin type 2

    Wen, Sharon X.; Teel, Louise D.; Judge, Nicole A.; O’Brien, Alison D.

    2006-01-01

    Hemolytic uremic syndrome, the leading cause of kidney failure in children, often follows infection with enterohemorrhagic Escherichia coli and is mediated by the Shiga type toxins, particularly type 2 (Stx2), produced by such strains. The challenge in protecting against this life-threatening syndrome is to stimulate an immune response at the site of infection while also protecting against Shiga intoxication at distal sites such as the kidney. As one approach to meeting this challenge, we sou...

  14. 3g mesalazine granules are superior to 9mg budesonide for achieving remission in active ulcerative colitis: a double-blind, double-dummy, randomised trial.

    Budesonide may be an effective therapy for mild-to-moderately active ulcerative colitis (UC). This study aimed to demonstrate non-inferiority for oral 9mg budesonide once daily (OD) versus 3g mesalazine granules OD. This was an eight-week randomised, double-blind, double-dummy, multicentre study in which patients with mild-to-moderately active UC, defined as Clinical Activity Index (CAI) ≥6 and Endoscopic Index (EI) ≥4, received budesonide (Budenofalk® 3mg capsules×3) or mesalazine (Salofalk® 1000mg granules×3). The primary endpoint was clinical remission at week 8 (CAI ≤4 with stool frequency and rectal bleeding subscores of "0"). 343 patients were randomised (177 budesonide, 166 mesalazine). Fewer patients achieved the primary endpoint with budesonide versus mesalazine (70/177 [39.5%] versus 91/166 [54.8%]) with a difference in proportions of -15.3% (95% CI [-25.7%, -4.8%]; p=0.520 for non-inferiority). The median time to first resolution of symptoms was 14.0 days (budesonide) and 11.0 days (mesalazine) (hazard ratio 1.19; 95% CI [0.94, 1.51]). Mucosal healing was observed in 54/177 (30.5%) budesonide patients versus 65/166 (39.2%) mesalazine patients, a difference of -8.6% (95% CI [-18.7%, 1.4%]; p=0.093). The incidences of adverse events (budesonide 26.6%, mesalazine 25.3%) and serious adverse events (budesonide 1.7%, mesalazine 1.2%) were similar. Once-daily 3g mesalazine administered as granules is superior to 9mg budesonide OD administered as capsules for achieving remission in mild-to-moderately active UC. However, it is noteworthy that remission of UC was attained in about 40% of budesonide-treated patients with a rapid onset of resolution. Copyright © 2010. Published by Elsevier B.V.

  16. Colorectal Cancer Chemoprevention by Mesalazine and Its Derivatives

    Carmine Stolfi

    2012-01-01

    Full Text Available Patients with inflammatory bowel disease (IBD face an increased lifetime risk of developing colorectal cancer (CRC. Independent factors associated with increased risk include long disease duration, extensive colonic involvement, young age at onset of IBD, severity of inflammation, primary sclerosing cholangitis, backwash ileitis, and a family history of CRC, thus emphasising the role of intestinal inflammation as an underlying mechanism. This notion is also supported by the demonstration that the use of certain drugs used to attenuate the ongoing mucosal inflammation, such as mesalazine, seems to associate with a reduced incidence of colitis-associated CRC. In the last decade, work from many laboratories has contributed to delineate the mechanisms by which mesalazine alters CRC cell behaviour. In this paper, we review the available experimental data supporting the ability of mesalazine and its derivatives to interfere with intracellular signals involved in CRC cell growth.

  17. Lithium Intoxication

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

    Evaluation of: Kruis W, Meier E, Schumacher M, Mickisch O, Greinwald R, Mueller R; German SAG-20 Study Group. Randomised clinical trial: mesalazine (Salofalk granules) for uncomplicated diverticular disease of the colon - a placebo-controlled study. Aliment. Pharmacol. Ther. 37(7), 680-690 (2013). Although diverticular disease (DD) is one of the commonest diseases in the western world, robust evidences about its treatment are lack so far. A recent, placebo-controlled study found mesalazine effective in obtaining pain relief in patients suffering from DD. A brief comment is provided herein in order to assess the rationale of this drug in treating DD.

  19. Mesalazine-induced myopericarditis in a patient with ulcerative colitis

    Jalal Asadi

    2017-12-01

    Full Text Available A 25-year-old male with a background of ulcerative colitis presented with a two-week history of central chest pain. His ECG on presentation showed global T wave inversion with a peak troponin I of 165 ng/mL. Clinical diagnosis of myopericarditis/myocarditis was made. Echocardiography and cardiac magnetic resonance (MR confirmed the diagnosis. On detailed assessment of his medication history, mesalazine was suspected as an etiological factor, with discontinuation resulting in an improvement in symptoms, inflammatory markers and cardiac enzymes. This is a unique case of mesalazine-induced myopericarditis on a background of inflammatory bowel disease.

  20. Evaluation of renal function following administration of ethane-1-hydroxy-1,1-biphosphonate (EHBP) in animals submitted to oral intoxication with uranyl nitrate

    2003-01-01

    Workers involved in the processes of extraction, purification and manufacture of uranium of nuclear plants are occupationally exposed to both natural and enriched uranium. Several chelating agents (TIRON, EDTA, BAI, etc.) have been tested in terms of their capacity to sequester uranium before it reaches its target organs. Our laboratory has studied a first generation biphosphonate, ethane-1-hydroxy-1,1-biphosphonate (EHBP). We have shown that treatment with EHBP induces survival rates of 75% and 100% in adult and suckling rats respectively intoxicated with an intraperitoneal injection of uranyl nitrate. There are no data available to date on the renal function following treatment with EBHP to counteract the toxic effects of an oral lethal dose of uranyl nitrate. The aim of the present study was to assay creatininemia and uremia as end-points to assess renal function. The results obtained reveal that the alterations in renal function induced by oral uranyl nitrate intoxication can be reduced at 48 hours and reverted at 14 days by subcutaneous or oral administration of EHBP.

    2016-06-01

    Full Text Available Objective: To analyze the clinical effect of Etiasa (mesalazine slow-release granules in combined with mesalazine suppository in the treatment of ulcerative colitis and the medication safety. Methods: A total of 82 patients with ulcerative colitis who were admitted in our hospital from June, 2013 to January, 2015 were included in the study and randomized into the observation group (n=42 and the control group (n=40. The patients in the two groups were orally given Etiasa. The patients in the observation group were given additional mesalazine suppository. Medication for 4-6 weeks was regarded as one course. The symptom relieving, the total remission rate of mucosal lesions after one course, the change of DAI 3 and 6 months after treatment, and the serum IL-8 and IL-10 levels before and after treatment in the two groups were compared. Results: The comparison of quantitative scoring of clinical efficacy and DAI before treatment between the two groups was not statistically significant. The above indicators after treatment in the observation group were significantly reduced and the reduced degree was significantly greater than that in the control group. The total effective rate in the observation group was significantly higher than that in the control group. IL-8 level after treatment in the observation group was significantly lower than that in the control group, while IL-10 level was significantly higher than that in the control group. The comparison of the occurrence rate of adverse reactions during the treatment process between the two groups was not statistically significant. Conclusions: Etiasa in combined with mesalazine suppository in the treatment of ulcerative colitis can increase the local drug concentration, and correct the imbalance of anti-inflammatory cytokines and proinflammatory cytokines, with a significant efficacy.

    1982-01-01

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

    2016-09-01

    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. © 2015 Blackwell Verlag GmbH.

  7. Baclofen Intoxication

    Canan Bor

    2015-12-01

    Full Text Available Baclofen is a β-(ρ-chlorophenyl derivative of the neurotransmitter gamma-aminobutyric acid (GABA and is usually prescribed for spasticity of spinal cord origin, intractable hiccup, trigeminal neuralgia, hemifacial spasm, and tardive dyskinesia. The usual recommended daily dose ranges from 40-80 mg, and the total dose should not exceed 80 mg per day. A 41 year old woman using baclofen for migraine therapy intended suicide after a bitter headache attack by taking 37 tablets, 10 mg in each. On arrival to emergency room, she was conscious and co-operable, but somnolent, her pupils were normoisocoric and light reflex was intact bilaterally. On her follow up, respiratory insufficiency and unconsciousness was observed so she was entubated orotracheally and transferred to intensive care unit (ICU for advanced tests and therapy. No pathology was determined on cranial CT. On ICU follow up, she was unconscious and mechanically ventilated, her Glasgow Coma Scale was 3/15 (E1M1VE and pupils were mid-dilated with no light reflex. Since she was again conscious, oriented and co-operable on 19th hour of arrival to ICU and 20th hour of arrival to emergency room, spontaneous breathing trials was started. Extubation was carried out on her 31th hour of arrival to ICU and 32th hour of arrival to emergency room. In conclusion; since baclofen overdose may cause deep coma, it should also be included in differential diagnosis. According to our opinion, performing diagnostic toxicological tests is not always possible that’s why history and physical examination is fundamental in case of baclofen intoxication and we can get good results by giving frequent neurological examination, supportive and extracorporeal therapy in such a case.

    Full Text Available Andrey E Dorofeyev1, Elena A Kiriyan2, Inna V Vasilenko1, Olga A Rassokhina1, Andrey F Elin11National Medical University, Donetsk, Ukraine; 2Gastroenterological Center of Poltava Hospital Clinic, Poltava, UkraineObjectives: The aim of this study was to analyze the clinical efficacy and cytomorphologic changes of colon mucosa following the treatment of patients suffering from irritable bowel syndrome (IBS with mesalazine (5-aminosalicylic acid [5-ASA].Methods: In this controlled, randomized, blind clinical trial, a total of 360 patients with varying subtypes of IBS were randomly treated with 500 mg of mesalazine qid or by standard therapy without mesalazine for a period of 28 days. Pre- and post-treatment pain intensity, pain duration, meteorism, stool abnormalities and endoscopic parameters were monitored, and biopsies or brush biopsies were examined histologically.Results: Treatment of IBS patients with mesalazine significantly reduced intensity and duration of pain in all subtypes of IBS, except for duration of pain in the subtype “undifferentiated”, where the difference was not significant. In addition, in patients with diarrhea type and undifferentiated type of IBS, mesalazine also significantly reduced the abnormal stool pattern. In comparison to the control group, administration of mesalazine reduced the incidence of endoscopic and cytomorphologic changes of the bowel mucosa, including changes in colon mucus, mucus production, cytologic or histologic parameters, epithelial cell degeneration, appearance of leukocytes and macrophages and cell infiltrations.Conclusion: Mesalazine was effective in reducing several symptoms characteristic of IBS. It significantly reduced pain intensity and duration and improved cytohistologic parameters of the bowel mucosa.Keywords: 5-amino salicylic acid, 5-ASA, abdominal pain, irritable bowel syndrome, IBS, meteorism, stool abnormalities

    Full Text Available Context Irritable bowel syndrome (IBS is a functional bowel disease characterized by abdominal pain and altered intestinal habits. The pathophysiology of IBS remains unclear. Recent studies have demonstrated that some IBS patients, especially in diarrhea-predominant IBS (IBS-D, display persistent signs of minor mucosal inflammation and a modified intestinal microflora. The mesalazine has known intestinal anti-inflammatory properties. Saccharomyces boulardii is a probiotic used for a long time in treatment of diarrhea, including infectious diarrhea. Objective Evaluate the effects of mesalazine alone, combined therapy of mesalazine with liophylised Saccharomyces boulardii or alone on symptoms of IBS-D patients. Methods Based on Rome III criteria, 53 IBS-D patients (18 year or more were included. To exclude organic diseases all patients underwent colonoscopy, stool culture, serum anti-endomisium antibody, lactose tolerance test and ova and parasite exam. Patients were divided in three groups: mesalazine group (MG - 20 patients received mesalazine 800 mg t.i.d. for 30 days; mesalazine and Saccharomyces boulardii group (MSbG - 21 patients received mesalazine 800 mg t.i.d. and Saccharomyces boulardii 200 mg t.i.d. for 30 days and; Saccharomyces boulardii group (SbG – 12 patients received Sb 200 mg t.i.d. for 30 days. Drugs that might have any effect on intestinal motility or secretion were not allowed. Symptom evaluations at baseline and after treatment were performed by means of a 4-point likert scale including: stool frequency, stool form and consistency (Bristol scale, abdominal pain and distension. Paired t test and Kruskal-Wallis test were used for statistical analyses. Results Compared to baseline, there were statistically significant reduction of symptom score after 30 th day therapy in all three groups: MG (P<0.0001; MSbG (P<0.0001 and in SbG (P = 0.003. There were statistically significant differences in the symptom score at 30 th day

    Full Text Available We investigated the effect of DWac on the gut microbiota composition in mice with 2,3,6-trinitrobenzenesulfonic acid- (TNBS- induced colitis. Treatment with DWac restored TNBS-disturbed gut microbiota composition and attenuated TNBS-induced colitis. Moreover, we examined the effect of DWac in mice with mesalazine-resistant colitis (MRC. Intrarectal injection of TNBS in MRC mice caused severe colitis, as well as colon shortening, edema, and increased myeloperoxidase activity. Treatment with mesalazine (30 mg/kg did not attenuate TNBS-induced colitis in MRC mice, whereas treatment with DWac (30 mg/kg significantly attenuated TNBS-induced colitis. Moreover, treatment with the mixture of mesalazine (15 mg/kg and DWac (15 mg/kg additively attenuated colitis in MRC mice. Treatment with DWac and its mixture with mesalazine inhibited TNBS-induced activation of NF-κB and expression of M1 macrophage markers but increased TNBS-suppressed expression of M2 macrophage markers. Furthermore, these inhibited TNBS-induced T-bet, RORγt, TNF-α, and IL-17 expression but increased TNBS-suppressed Foxp3 and IL-10 expression. However, Th2 cell differentiation and GATA3 and IL-5 expression were not affected. These findings suggest that DWac can ameliorate MRC by increasing the polarization of M2 macrophage and correcting the disturbance of gut microbiota and Th1/Th17/Treg, as well as additively attenuating MRC along with mesalazine.

    1987-10-01

    In a prospective randomized placebo controlled double blind study, the prophylactic effect of Mesalazine (5-aminosalicylic acid, 5-ASA) as suppositories (3x250 mg/day) on radiation induced proctitis during radiotherapy for prostatic carcinoma was studied. The study ended when 16 patients had been included (5-ASA: Eight, placebo: Eight) because of severe side effects in the 5-ASA group. 75% of patients treated with 5-ASA reported symptoms of a severe proctitis while only one patient in the placebo group had similar complaints. The application of Mesalazine as suppositories is not useful in preventing radiation induced proctitis during radiotherapy of prostate carcinoma.

    Workers involved in the processes of extraction, purification and manufacture of uranium of nuclear plants are occupationally exposed to both natural and enriched uranium. Several chelating agents (TIRON, EDTA, BAI, etc.) have been tested in terms of their capacity to sequester uranium before it reaches its target organs. Our laboratory has studied a first generation biphosphonate, ethane-1-hydroxy-1,1-biphosphonate (EHBP). We have shown that treatment with EHBP induces survival rates of 75% and 100% in adult and suckling rats respectively intoxicated with an intraperitoneal injection of uranyl nitrate. There are no data available to date on the renal function following treatment with EBHP to counteract the toxic effects of an oral lethal dose of uranyl nitrate. The aim of the present study was to assay creatininemia and uremia as end-points to assess renal function. The results obtained reveal that the alterations in renal function induced by oral uranyl nitrate intoxication can be reduced at 48 hours and reverted at 14 days by subcutaneous or oral administration of EHBP.

  18. [Acute intoxication with fenspiride].

    Chodorowski, Zygmunt; Sein Anand, Jacek; Korolkiewicz, Roman

    2004-01-01

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

  20. A case of pyoderma gangrenosum with ulcerative colitis treated with mesalazine.

    Lee, Jae In; Park, Hyun Jeong; Lee, Jun Young; Cho, Baik Kee

    2010-11-01

    Pyoderma gangrenosum (PG) manifests as recurrent deep ulceration of the skin and PG is associated with a variety of disorders. Approximately 30% of the cases of PG develop in patients with inflammatory bowel disease. A 34-year-old woman presented with a one-week history of recurrent ulcers on the right cheek and back. She was diagnosed with ulcerative colitis (UC) 4 years previously and with PG 1 year previously. The clinical course of the skin lesions followed the status of her UC. The patient's skin lesions and bowel symptoms were not improved with prednisolone. After she was started on mesalazine, we observed rapid resolution of skin lesions and bowel symptoms. Herein, we report a case of recurrent PG with UC, and we discuss the possible association between these two conditions, and the efficacy of mesalazine therapy for the treatment of PG combined with UC.

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

    Alcohol intoxication increases the risk of highway accidents, the relative risk of crash probability increasing as a function of blood alcohol content (BAC). Because alcohol use is more prevalent than use of other drugs, more is known about the relationship between alcohol use and driving. Most states presume a BAC of .10% to be evidence of drunk…

    2016-10-01

    Symptomatic uncomplicated diverticular disease (SUDD) is a common gastrointestinal disease, because it affects about one fourth of the patient harboring colonic diverticula. To assess the effectiveness of mesalazine in improving symptoms (namely abdominal pain) and in preventing diverticulitis occurrence in patients with SUDD. Only randomized clinical trials (irrespective of language, blinding, or publication status) that compared mesalazine with placebo or any other therapy in SUDD were evaluated. The selected endpoints were symptom relief and diverticulitis occurrence at maximal follow-up. Absolute risk reduction (ARR, with 95% confidence interval) and the number needed to treat were used as measures of the therapeutic effect. Six randomized clinical trials enrolled 1021 patients: 526 patients were treated with mesalazine and 495 with placebo or other therapies. Symptom relief with mesalazine was always larger than that with placebo and other therapies. However, absolute risk reduction was significant only when mesalazine was compared with placebo, a high-fiber diet, and low-dose rifaximin. The incidence of diverticulitis with mesalazine was lower than that observed with placebo and other treatments, being significant only when compared with placebo. Mesalazine is effective in achieving symptom relief and primary prevention of diverticulitis in patients with SUDD.

    Botulinum toxin is an egzotoxin produced by Gram positive bacteria Clostridium botulinum. It is among the most potent toxins known. The 3 main clinical presentations of botulism are as follows: foodborne botulism, infant botulism and wound botulism. The main symptom of intoxication is flat muscles paralysis. The treatment is supportive care and administration of antitoxin. In prevention the correct preparing of canned food is most important. Botulinum toxin is accepted as a biological weapon. © 2015 MEDPRESS.

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

  12. [Intoxications with plants].

    Kupper, Jacqueline; Reichert, Cornelia

    2009-05-01

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

    Mesalazine seems to be effective in preventing recurrence of acute uncomplicated diverticulitis (AUD), but the optimal mesalazine scheme to achieve these results is still debated. To assess the effectiveness of two different mesalazine-based treatments in preventing recurrence of AUD and the occurrence of other complications of diverticular disease (DD) during a long-term follow-up. We reviewed 311 patients suffer from recent episode of AUD and undergoing to mesalazine treatment: 207 (group A, 105 males, median age 63 years, range 47-74 years) were treated with mesalazine 1.6 g for 10 days each month, whilst 104 (group B, 55 males, median age 65 years, range 50-72 years) were treated with mesalazine 1.6 g every day. Patients were followed-up every 6 months (median 7.5 months, range 5-13 months). Patients were followed-up for a mean time of 3 years (range 12-72 months). Overall, occurrence of complication recurred more frequently in group A than in group B (p = 0.030, log-rank test). Acute diverticulitis recurred in 17 (8.2%) patients in group A and in 3 (2.9%) in group B; diverticular bleeding occurred in 4 (1.9%) patients in group A and in 1 (0.96%) patient in group B; surgery was required in 3 (1.4%) patients in group A and in no (0%) patient in group B. This is the first study showing that long-term mesalazine treatment is significantly better that intermittent mesalazine treatment in preventing occurrence of DD complications after an attack of acute diverticulitis.

  14. Neurological aspects of lead intoxication

    Lehner, H

    1980-05-08

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

    Tablets of mesalazine covered with a pH-dependent coating, labelled by an original technique with technetium-99m, were administered to 12 patients, 9 with Crohn's disease, 3 of which recurrent, 1 with ulcerative colitis, and 2 with irritable bowel syndrome, with the aim of verifying in vivo the intestinal site of disintegration and how the contents spread throughout the intestine. In all cases the tablet was broken down in the distal ileum at extremely variable intervals, from 5 to 27 h, and the contents spread into the nearby loops and into the colon. The notable differences in the residence time of the whole tablet in the ileum can be explained by differences in adhesion the inflamed mucosa and by a lower pH in the part of the ileum affected by the disease. 7 refs., 2 figs., 1 tab.

  17. Unpacking intoxication, racialising disability.

    Chen, Mel Y

    2015-06-01

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

  18. Chelation in Metal Intoxication

    Swaran J.S. Flora

    2010-06-01

    Full Text Available 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.

  19. Use of mesalazine slow release suppositories 1 g three times per week to maintain remission of ulcerative proctitis: a randomised double blind placebo controlled multicentre study

    Marteau, P; Crand, J; Foucault, M; Rambaud, J

    1998-01-01

    Background—Daily administration of rectal formulations of mesalazine is effective in preventing relapse of ulcerative proctitis. Maintenance of remission with lower doses would be an advantage. 
Aim—The efficacy of mesalazine suppositories (Pentasa) 1 g three times a week v placebo to maintain remission in patients with cryptogenetic proctitis was studied. 
Methods—Ninety five patients with cryptogenetic proctitis were randomised within two weeks of remission to receive for one year or until relapse three suppositories per week of either Pentasa (n=48) or placebo (n=47). In the case of a relapse, the patients received one suppository/day. 
Results—It was found that 25 of 48 subjects v 18 of 47 remained in remission in the mesalazine and placebo groups respectively. The relapse rate was lower in the mesalazine group for the following time intervals: 0-90 days (19% v 38%, p=0.035), 0-180 days (29% v 54%, p=0.017), 0-270 days (38% v 60%, p=0.031), and 0-365 days (48% v 62%, p=0.18). Treatment of relapse with one suppository/day induced remission in 11 of 18 and 2 of 26 patients in the mesalazine and placebo groups respectively (p=0.001). Overall, 61% v 28% patients remained in the protocol and were in remission at one year (p=0.001). Tolerance was good. 
Conclusion—Mesalazine suppositories 1 g three times a week are effective for preventing relapses of cryptogenetic proctitis. Increasing the dose to 1 g/day is effective in a high proportion of subjects who relapsed.

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

    Mesalazine suppositories are recommended and widely used as the standard therapy in induction and maintenance of remission for proctitis. To evaluate the efficacy of mesalazine suppositories in patients with ulcerative colitis (UC) and rectal inflammation; and in patient groups categorised by the extent of lesions. This study was a phase III multicentre, randomised, double-blind, placebo-controlled, parallel-group study. Mild-to-moderate UC patients with rectal inflammation were randomly assigned either a 1 g mesalazine or placebo suppository. The suppository was administered in the rectum once daily for 4 weeks. The primary efficacy end point was the rate of endoscopic remission (mucosal score of 0 or 1) after 4 weeks. The endoscopic remission rates after 4 weeks in the mesalazine and placebo suppository groups were 81.5% and 29.7%, respectively, and the superiority of mesalazine to placebo was confirmed (P suppositories in all types of UC patients with rectal inflammation was confirmed for the first time in a double-blind, placebo-controlled, parallel-group study (JapicCTI- 111421). © 2013 John Wiley & Sons Ltd.

    A simple, specific and sensitive LC-MS/MS method was developed and validated for the determination of mesalazine in beagle dog plasma. The plasma samples were prepared by protein precipitation, then the separation of the analyte was achieved on a Waters Spherisorb C6 column (150 × 4.6 mm, 5 µm) with a mobile phase consisting of 0.2% formic acid in water-methanol (20:80, v/v). The flow rate was set at 1.0 mL/min with a split ratio of 3:2. Mass spectrometric detection was achieved by a triple-quadrupole mass spectrometer equipped with an electrospray source interface in positive ionization mode. Quantitation was performed using selected reaction monitoring of precursor-product ion transitions at m/z 154 → m/z 108 for mesalazine and m/z 285 → m/z 193 for diazepam (internal standard). The linear calibration curve of mesalazine was obtained over the concentration range 50-30,000 ng/mL. The matrix effect of mesalazine was within ±9.8%. The intra- and inter-day precisions were dogs after rectal administration of mesalazine suppository. Copyright © 2014 John Wiley & Sons, Ltd.

  5. Sucralfate versus mesalazine versus hydrocortisone in the prevention of acute radiation proctitis during conformal radiotherapy for prostate carcinoma. A randomized study

    Sanguineti, G.; Franzone, P.; Marcenaro, M.; Vitale, V.; Foppiano, F.

    2003-01-01

    Purpose: To assess whether the topical use of steroids or 5-aminosalicylic acid (5-ASA) is superior to sucralfate in preventing acute rectal toxicity during three-dimensional conformal radiotherapy (3DCRT) to 76 Gy. Patients and Methods: Patients undergoing 3DCRT for prostate carcinoma at our institution were offered to be randomized to sucralfate 3 g in 15 ml suspension enema (Antepsin trademark ), mesalazine 4 g gel enema (Enterasyn trademark), or hydrocortisone 100 mg foam enema (Colifoam trademark ). Randomization was blind to the treating physician but not to the patient. Sucralfate was chosen as control arm. Topical treatment had to be performed once daily, starting on day 1 of 3DCRT. Acute rectal toxicity was scored weekly according to RTOG criteria. Time to occurrence of grade 2+ acute rectal toxicity was taken as endpoint. Results: The trial was opened in August 1999, and after the first 24 patients had been treated, arm 2 was discontinued because of eight patients receiving mesalazine, seven actually developed acute rectal toxicity (five patients grade 3 and two patients grade 2). Until May 2001, 134 consecutive patients were randomly assigned to sucralfate (63 patients), mesalazine (eight patients) or hydrocortisone (63 patients). The cumulative incidence of acute rectal toxicity at the end of treatment by arm is 61.9 ± 6.1%, 87.5 ± 11.7%, and 52.4 ± 6.2% for arms 1, 2, and 3, respectively. The difference between the mesalazine group and the sucralfate group is highly significant (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.1-5.7; p = 0.03). At both uni- and multivariate analysis taking into account several patients and treatment covariates, the difference between hydrocortisone and sucralfate is not significant (HR 0.7, 95% CI 0.5-1.2; p = 0.2). Conclusion: Topical mesalazine is contraindicated during radiotherapy. Hydrocortisone enema is not superior to sucralfate in preventing acute rectal toxicity. (orig.)

    Biochemical diagnostics of fatal opium intoxication remains a topical problem in forensic medical science and practice. We investigated materials obtained in the course of forensic medical expertise of the cases of fatal opium intoxication. The study revealed significant differences between myoglobin levels in blood, urine, myocardium, and skeletal muscles. The proposed approach to biochemical diagnostics of fatal opium intoxication enhances the accuracy and the level of evidence of expert conclusions.

  9. Lead and zinc intoxication in companion birds.

    Puschner, Birgit; Poppenga, Robert H

    2009-01-01

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

  10. Radioimmunoassay of serum digoxin levels in digitalis intoxication

    Arendt, G.

    1981-01-01

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

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

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

    Wada, Kiyoshi

    2015-09-01

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

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

  17. A randomized double blind placebo controlled multicenter study of mesalazine for the prevention of acute radiation enteritis

    Background and purpose: Symptoms of acute radiation enteritis (ARE), dominated by diarrhea, occur in more than 70% of patients receiving pelvic irradiation. Eicosanoids and free radicals release have been implicated in the pathogenesis. Mesalazine (5-ASA) is a potent inhibitor of their synthesis in the mucosa and could therefore be of some interest in preventing ARE. Patients and methods: The study was performed in six radiotherapy units in France who agreed on standardized irradiation procedures. One hundred and fifty-three patients planned for external beam radiotherapy to the pelvis ≥45 Gy for prostate (n = 97) or uterus (n = 54) cancer were randomized on a double blind basis to receive prophylactic 5-ASA (4 g/day Pentasa[reg]) or placebo. Patients with concomitant chemotherapy were excluded. Prostate and uterus cancers were chosen since these centropelvic tumors require a similar radiotherapy protocol during the first step of treatment and involve a comparable volume of small intestine. The symptoms of ARE and their severity were assessed every week during irradiation, and 1 and 3 months after its end. All patients followed a low fiber and low lactose diet. End points were diarrhea, use of antidiarrheal agents, abdominal pain, and body weight. Efficacy was evaluated using intention to treat. Results: (means ± SD) Groups did not differ for age (mean 64 ± 9 years), sex, tumor site, or irradiation procedure. During irradiation, diarrhea occurred in 69% and 66% of the 5-ASA and placebo groups, respectively (χ 2 , P = 0.22). Curves of survival without diarrhea did not differ between groups (logrank P = 0.09). Severity of diarrhea did not differ between groups except at d15 where it was significantly more severe in the 5-ASA group (ANOVA P = 0.006). Duration of diarrhea did not differ (22 ± 15 days in both groups, P = 0.88). Abdominal pain was less frequently reported in the 5-ASA group at d28 (34% vs. 51%, P 0.048).

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

  20. Effects of ethanol intoxication on speech suprasegmentals

    Hollien, Harry; Dejong, Gea; Martin, Camilo A.; Schwartz, Reva; Liljegren, Kristen

    2001-12-01

    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.

  1. Erythrocyte fluorescence and lead intoxication.

    Clark, K G

    1976-01-01

    Blood samples from people exposed to inorganic lead were examined by fluorescence microscopy for excess erythrocyte porphyrin. With continued lead absorption, fluorescent erythrocytes appeared in the circulation of workers handling this metal or its compounds, and they progressively increased in number and brilliance. These changes ensued if the blood lead concentration was maintained above 2-42 mumol/l (50 mug/100 ml), and preceded any material fall in the haemoglobin value. At one factory, 62-5% of 81 symptomless workers showed erythrocyte fluorescence attributable to the toxic effects of lead. Excess fluorocytes were found in blood samples from a child with pica and three of her eight siblings. These four were subsequently shown to have slightly increased blood lead concentrations (2-03 to 2-32 mumol/l). Fluorescence microscopy for excess erythrocyte porphyrin is a sensitive method for the detection of chronic lead intoxication. A relatively slight increase in the blood lead is associated with demonstrabel changes in erythrocyte porphyrin content. The procedure requires little blood, and may be performed upon stored samples collected for lead estimation. The results are not readily influenced by contamination, and provide good confirmatory evidence for the absorption of biochemically active lead. PMID:963005

  2. Total gastrectomy due to ferric chloride intoxication.

    Menéndez, A Mesut; Abramson, Leonardo; Vera, Raúl A; Duza, Guillermo E; Palermo, Mariano

    2015-09-01

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

  3. Intox, detox, antidotes - Evidence based diagnosis and treatment of acute intoxications.

    Schaper, Andreas; Ebbecke, Martin

    2017-11-01

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

    S.F. Andrade

    2007-10-01

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

    The case of a female 68 years old patient is described. Here, a chronic lead intoxication was diagnosed after a two year old medical history with increasing attacks of colic-like abdominal pain often described as life-threatening. After repeated hospitalizations and intensive search for the cause of the symptoms, porphyria and anemia was found to be a sign of a chronic lead poisoning. The blood lead concentrations were always about a level of 600 {mu}g/L. The source of exposure could not be found by now. Neither home inspection nor environmental investigations have shown a recent source of lead intake by the patient. However, a possible occupational source of lead exposure at a blast furnace was established by anamnesis for 1952 to 1962. Thus, osteoporosis induced lead mobilisation was suspected. Noticeable are the results of the six abdominal survey radiographies taken during hospitalization within one year; three radiographies were taken following clinical admission and three before discharge of the patient. In comparison, the course shows a chronic relapsing alimentary supply from metallic particles of unknown genesis. The patient was treated with the sodium salt of 2,3-dimercapto-1-propansulfonic acid (DMPS, Dimaval{sup TM}). She was free of complain afterwards. Following therapy, the blood lead concentrations fell under a level of 400 {mu}m/L, but after several weeks the lead level raised up to the original level of 600 {mu}g/L. (orig.)

    Ayahuasca is a hallucinogenic tea that is most commonly comprised of the vine Banisteriopsis caapi alone or in combination with other plants such as Psychotria viridis. This concoction results in an orally active form of dimethyltryptamine (DMT), a hallucinogenic amine. Despite use in South America as a medicinal agent and component in religious ceremonies, interest in its recreational use and spiritual effects has led to increased use in the United States. We describe a unique case following ingestion of ayahuasca tea in a patient with history of schizophrenia resulting in personal injury and property damage. A review of ayahuasca toxicity and evaluation of serious adverse effects is also presented. PMID:29682363

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

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

    2016-01-01

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

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

  16. Effects of cadmium and monensin on renal and cardiac functions of mice subjected to subacute cadmium intoxication

    Ivanova Juliana

    2014-06-01

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

  17. Cocklebur (Xanthium strumarium, L. var. strumarium) intoxication in swine: review and redefinition of the toxic principle.

    Stuart, B P; Cole, R J; Gosser, H S

    1981-05-01

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

    2009-03-01

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

  19. Lead Intoxication in Children in Birmingham

    1973-01-01

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

  20. Accidental intoxication with Veratrum album.

    Grobosch, T; Binscheck, T; Martens, F; Lampe, D

    2008-01-01

    A 49-year-old man consumed two glasses (approximately 2 x 20 mL) of a beverage containing yellow gentian (Gentiana lutea). Shortly after ingestion, he developed nausea, vomiting, and oral paraesthesia. On admission to the hospital he suffered from severe bradycardia (35 beats/min) and hypotension (50/30 mm Hg), and he was treated with activated charcoal, antiemetics (metoclopramide, ondansetron), atropine, and intravenous electrolytic solution. The initial suspicion of Veratrum poisoning could be confirmed by identifying protoveratrines A (ProA) and protoveratrine B (ProB) in a sample from the beverage as well as in the patients serum by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS-MS). The yellow-colored beverage contained 25% ethanol (by headspace gas chromatography), 20.4 mg/L ProA, and 13.7 mg/L ProB. The serum concentration of ProA was 1162 ng/L and ProB was 402 ng/L. Veratridine, cevadine, and jervine were not detected, neither in the beverage nor in the serum sample. The lower limits of quantitation for all compounds is 10 microg/L (S/N > 10, beverage) and 100 ng/L (S/N > 10, serum). After treatment, the patient completely recovered from the symptoms within 24 h and was discharged from the hospital. The analytical method described was developed for the simultaneous identification and quantitation of five Veratrum alkaloids. The method is based on a liquid-liquid extraction followed by LC-MS-MS analysis. The time needed for analysis was 6 min.

    2014-09-01

    A 26-year-old man was found unable to move after oral consumption of 120 mL of RiUP X5® (containing 5 g/100 mL minoxidil) as a suicidal attempt. The patient complaining of frequent vomiting and weakness was transferred to our hospital. Findings on arrival: GCS E4V5M6; respiratory rate 24/ min; blood pressure 83/43 mmHg; pulse 152/min, regular; SpO₂97% (oxygen by mask: 6 L/min); thus, the patient was in shock. The systolic blood pressure and the pulse rate improved to about 90 mmHg and to about 130/min, respectively, in response to rapid intravenous infusion of 2,000 mL of lactated Ringer's solution. His circulatory condition tended to improve with parenteral fluid infusion alone. Forty hours after admission, however, heart failure developed due to excessive I.V. fluid infusion and abnormal body fluid distribution associated with delayed vascular smooth muscle relaxation; therefore, mechanical ventilation was initiated. Simultaneously, intravenous noradrenaline infusion was started because of a fall of the blood pressure. Subsequently, as the patient's respiratory and circulatory conditions gradually improved, he was weaned from mechanical ventilation, and the noradrenaline infusion was discontinued at 108 hours after admission. The patient made favorable progress and was discharged home on the 9th hospital day. Minoxidil exerts adverse effects mainly on the cardiovascular system. Since minoxidil is an over-the-counter drug readily available to the public, and emergency physicians should be aware of its severe toxicity.

    Full Text Available Diagnosis of nerve agent intoxication is based on anamnestic data, clinical signs and laboratory examination. For acute poisoning, cholinesterase activity in the blood (erythrocyte AChE, plasma/serum BuChE is sensitive, simple and most frequent laboratory examination performed in biochemical laboratories. Specialized examinations to precise treatment (reactivation test or to make retrospective diagnosis (fluoride induced reactivation etc. can be conducted. Other sophisticated methods are available, too.

  4. [Intoxications specific to the Aquitaine region].

    Bédry, R; Gromb, S

    2009-07-01

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

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

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

  8. A safe strategy to decrease fetal lead exposure in a woman with chronic intoxication.

    Leiba, Adi; Hu, Howard; Zheng, Amin; Kales, Stefanos N

    2010-08-01

    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.

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

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

  12. PROTEOSE INTOXICATIONS AND INJURY OF BODY PROTEIN

    Cooke, J. V.; Whipple, G. H.

    1918-01-01

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

    Full Text Available Abdulsamet Erden,1 Hatice Karagoz,1 Hasan Hüseyin Gümüscü,1 Samet Karahan,1 Mustafa Basak,1 Fatma Aykas,1 Kadir Bulut,1 Ali Cetinkaya,1 Deniz Avci,1 Orhan Kürsat Poyrazoglu2 1Internal Medicine Department, 2Gastroenterology Department, Kayseri Training and Research Hospital, Kayseri, Turkey Abstract: Colchicine, an old and well-known drug, is an alkaloid extracted from Colchicum autumnale and related species. Colchicine inhibits the deposition of uric acid crystals and is an inhibitor of mitosis. Nausea, vomiting, abdominal pain, and diarrhea, with a massive loss of fluid and electrolytes are the first clinical symptoms of colchicine poisoning. Stomach lavage and rapid gastric decontamination with activated charcoal are crucial. An acute dose of about 0.8 mg/kg of colchicine is presumed to be fatal. We report the clinical outcomes of two different cases of colchicine intoxication for attempted suicide. The dose required for morbidity or mortality varies significantly. The dose of 1 mg/kg in the first case was directly related with mortality, while the dose of 0.2 mg/kg in the second was related with survival. The other difference between the patients was the time of arrival to hospital after ingestion. This period was 4 hours for case 1 and only 1, hour for case 2. The initiation of treatment later than 2 hours after ingestion of colchicine may significantly impair treatment because the absorption time for colchicine after oral administration is about 30–120 minutes. The rising lactate level and high anion gap metabolic acidosis in our patient (case 1 were attributed to lactic acidosis, so hemodialysis was performed, and the duration of hemodialysis was prolonged. Lactic acidosis in the first case was one of the reasons for mortality. The most important parameters which define the chance of survival are the dose of ingested drugs and the arrival time to hospital after ingestion. The patients must be monitored closely for lactic acidosis

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

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

    Full Text Available Aim: Liver function tests, including total plasma proteins, albumin, bilirubin and glucose were analyzed to find out the hepatocurative and hepatoprotective effects of Momordica charantia. Method: The study was divided into two categories. In first category, the livers of rabbits were intoxicated with acetaminophen, and then Momordica fruit extract was given to observe its hepatocurative effects. Results: The results indicated significant changes in concentrations of the parameters in acetaminophen-challenged rabbits. In the second category, treatment was started by giving Momordica fruit extract dose orally for 10 days and 15 days to two groups of rabbits, respectively. Then, livers of rabbits were damaged with acetaminophen and hepatoprotective effects of Momordica were observed. Conclusion: The results showed that the animals treated with Momordica fruit extract experienced less liver damage due to acetaminophen intoxication, indicating that Momordica has hepatoprotective properties.

  1. The Price of Eternal Vigilance: Women and Intoxication

    Michelle McClellan

    2016-04-01

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

  4. Acute alcohol intoxication impairs segmental body alignment in upright standing.

    Hafstrom, A; Patel, M; Modig, F; Magnusson, M; Fransson, P A

    2014-01-01

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

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

    Piperine is an abundant amide extracted from black pepper seeds which has been shown to have protective effects against cytotoxic and genotoxic carcinogenesis induced by certain chemical carcinogens and aflatoxin B₁ (AFB₁) in vitro. The aim of this work was to study, in vivo, the antigenotoxic potential of feed-added piperine on broiler chickens experimentally intoxicated with AFB₁, using micronucleus and comet assays. The antigenotoxicity assessment of 9-day-old chicks was performed on a total of 60 chickens divided into four groups of 15 broilers each: (C) control, (P) 60 mg·piperine kg -1 feed, (A) 0.5 mg·AFB₁·kg -1 body weight, (daily by oral route), and (P + A) co-treatment with piperine and AFB₁. The experiment was conducted for 26 days. Chicks intoxicated with AFB₁ showed significant genotoxic effects in the first 24 h post intoxication, and the effects remained in the other periods analyzed (48, 72, and 96 h and 26 days of treatment). The DNA damage in peripheral blood cells, the number of erythrocytes with micronuclei, and polychromatic-to-normochromatic erythrocyte ratio were significantly reduced or absent in the piperine/AFB₁ group. No significant differences were observed between the group piperine/AFB₁ and the control and piperine-alone groups. The addition 60 mg·kg -1 of piperine to the diet of the broiler chicks was safe, promoting beneficial effects in poultry health with respect to the toxic effects 0.5 mg·AFB₁·kg -1 body weight.

    Full Text Available Background The current study aimed to evaluate the efficacy of mesalazine plus bismuth on patients with irritable bowel syndrome (IBS and chief complaint of bloating. Methods The current quasi-experimental study, included patients with IBS and chief complaint of bloating and incomplete defecation. They were treated with masalazine and bismuth subcitrate and followed regularly based on monthly visits. The rate of symptoms relief, patients' satisfaction and any side effects were recorded during the surveillance. Results Overall, 42 patients (33 females and 9 males were included. The mean age of the patients was 35.9 years (ranged 22 - 67 years; 32%, 44% and 24% had high, medium and low socioeconomic levels, respectively; 96% of the patients were nonsmokers and just two patients had a history of alcohol consumption. Two patients had glucose intolerance, four had hypothyroidism and four had past history of valvular heart disease. In 20% of the patients, the family history for intestinal bowl disease (IBD was positive. Ten patients had a history of bloody diarrhea and no one had a history of any significant liver diseases. The most common symptoms of patients included incomplete defecation and tenesmus (41 patients, 97.6%, bloating (39 patients, 92.8%, abdominal fullness (35 patients, 83.3% and mucus discharge (30 patients, 71.4%. After an average six months of treatment (3 - 11 months, 69.1% of patients reported improvement of symptoms more than 50% (38.1%, ranged 75% - 100%, and 31% (ranged 50% - 75% indicated overall symptoms relief. The most significant improvement was reported for bloating (85%. There were no major side effects except minor degrees of diarrhea among 26% of the subjects. Conclusions The results of the study were indicative of improvement and symptom relief in the majority of patients and it seems that treatment prolongation up to six months could be a key factor to achieve better clinical responses. It is recommended that further

    The identification of the active phenolic compounds in the mixed extract of sea cucumber (Holothuria atra) body wall by high-performance liquid chromatography and an assessment of its hepatoprotective activity against thioacetamide-induced liver fibrosis in rats. Female Swiss albino rats were divided into four groups: normal controls; oral administration of a sea cucumber mixed extract (14.4 mg/kg of body weight) on days 2, 4, and 6 weekly for 8 consecutive weeks; intoxication with thioacetamide (200 mg/kg of body weight, intraperitoneally) on days 2 and 6 weekly for 8 wk; and oral administration of a sea cucumber extract and then intoxication with thioacetamide 2 h later for 8 wk. High-performance liquid chromatographic analysis of the sea cucumber mixed extract revealed the presence of some phenolic components, such as chlorogenic acid, pyrogallol, rutin, coumaric acid, catechin, and ascorbic acid. In vitro studies have shown that the extract has a high scavenging activity for the nitric oxide radical, a moderate iron-chelating activity, and a weak inhibitory effect of lipid peroxidation. The subchronic oral administration of sea cucumber extract to the rats did not show any toxic side effects but increased hepatic superoxide dismutase and glutathione peroxidase activities. The coadministration of sea cucumber extract and thioacetamide (protection modality) normalized serum direct bilirubin, alanine and aspartate aminotransferases, hepatic malondialdehyde, and hydroxyproline concentrations and antioxidant enzyme activities. In addition, the histologic examination of liver sections from the protection group that were stained with hematoxylin and eosin showed substantial attenuation of the degenerative cellular changes and regressions in liver fibrosis and necrosis induced by the thioacetamide intoxication. Sea cucumber mixed extract contains physiologically active phenolic compounds with antioxidant activity, which afforded a potential hepatoprotective activity

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

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

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

    Pelvic ultrasonography (US) is a simple and non-invasive radiologic test to evaluate the pelvic organs. It requires a full bladder for better visualization. Our case is a 14-year-old female with diabetes insipidus (DI) who admitted to the pediatric emergency service with the complaints of seizure and agitation after drinking 4 liters of water in one hour for a pelvic US examination due to work-up for delayed puberty. Her biochemical and clinical evaluation revealed water intoxication (WI). To our knowledge, this is the first WI case developed in a patient with DI. Here, we discuss the underlying factors leading to this complication and recommended an approach to obtain a better sonographic image without necessitating oral water intake to fill the urinary bladder.

    2013-01-01

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

    1982-01-01

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

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

  18. Patterns of substance abuse and intoxication among murderers.

    Yarvis, R M

    1994-01-01

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

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

    Jana Zdarova-Karasova

    2009-05-01

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

    2011-06-01

    To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl4 intoxicated Swiss albino mice. First group of mice (n=5) received CCl4 treatment at a dose of 0.5 mL/kg bw (i.p.) for 7 days. Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for 15 days. The third group was given both the turmeric extract (for 15 days, orally) and CCl4 (for last 7 days, i.p.). The fourth group was kept as a control. To study the liver function, the transaminase enzymes (SGOT and SGPT) and bilirubin level were measured in the serum of respective groups. For assaying the immunotherapeutic action of Curcuma longa (C. longa), non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups. The result of present study suggested that CCl4 administration increased the level of SGOT and SGPT and bilirubin level in serum. However, the aqueous extract of turmeric reduced the level of SGOT, SGPT and bilirubin in CCl4 intoxicated mice. Apart from damaging the liver system, CCl4 also reduced non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages. Administration of aqueous extract of C. longa offered significant protection from these damaging actions of CCl4 on the non specific host response in the peritoneal macrophages of CCl4 intoxicated mice. In conclusion, the present study suggests that C. longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

  8. Inhaled Loxapine for Agitation in Intoxicated Patients: A Case Series.

    Roncero, Carlos; Ros-Cucurull, Elena; Palma-Álvarez, Raúl Felipe; Abad, Alfonso Carlos; Fadeuilhe, Christian; Casas, Miquel; Grau-López, Lara

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

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

    Tomov, A

    1964-01-01

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

  10. Circumvention of Learning Increases Intoxication Efficacy of Nematicidal Engineered Bacteria.

    2016-03-18

    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.

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

  16. Sudden onset unexplained encephalopathy in infants: think of cannabis intoxication.

    Lavi, Eran; Rekhtman, David; Berkun, Yackov; Wexler, Isaiah

    2016-03-01

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

    2016-12-01

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

    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.

  2. Abnormal temperature control after intoxication with short-acting barbiturates.

    1981-09-01

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

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

    Morinis, A

    1985-01-01

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

  6. Effect of chronic lead intoxication on the distribution and elimination of amoxicillin in goats.

    Soliman, Ahmed M; Abu-Basha, Ehab A; Youssef, Salah A H; Amer, Aziza M; Murphy, Patricia A; Hauck, Catherine C; Gehring, Ronette; Hsu, Walter H

    2013-01-01

    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.

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

    Levitt, Ash; Schlauch, Robert C; Bartholow, Bruce D; Sher, Kenneth J

    2013-12-01

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

  8. Heme synthesis in the lead-intoxicated mouse embryo

    Gerber, G B; Maes, J

    1978-02-01

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

    1993-01-01

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

  11. Misleading Gastrointestinal Symptoms: The Ongoing Story of Chronic Lead Intoxication.

    Macedo, Guilherme; Lopes, Susana; Peixoto, Armando

    2016-10-01

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

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

    Objectives Episodes of agitation are frequent in intoxicated patients who have a substance use disorder, a psychiatric disorder or both (dual diagnosis). For managing the agitation, it is necessary to act promptly in a safe environment and addressing any underlying etiology. Inhaled loxapine improves symptoms of agitation in adults with psychiatric disorders (eg, schizophrenia) within 10 minutes of administration. Recently, some reports have documented the usefulness of loxapine in dual diagn...

  14. Artificial sweeteners, caffeine, and alcohol intoxication in bar patrons.

    Rossheim, Matthew E; Thombs, Dennis L

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

    We report a 14-year-old girl with an unusual pattern of leukoencephalopathy after intentional intoxication with morphine sulphate tablets. Toxicological analysis showed exceedingly high levels of morphine and its metabolites. MRI disclosed a leukoencephalopathy with high signal from the centrum semiovale, corpus callosum and cerebellar white matter on T2-weighted images. These findings could be only partially explained by a hypoxic-ischaemic event; neurotoxic effects must be considered in this atypical leukoencephalopathy. (orig.)

  18. Deleterious effects of magnesium intoxication upon the domestic broiler chick

    Lee, S.R.

    1984-01-01

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

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

  20. Peganum harmala L. Intoxication in a Pregnant Woman

    Mohamed Adnane Berdai

    2014-01-01

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

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

    Radlović Nedeljko

    2014-01-01

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

    Iraj Sedighi

    2012-05-01

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

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

    Colflesh, Gregory J H; Wiley, Jennifer

    2013-03-01

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

  5. When Do Friends Prevent Friends from Hooking Up Intoxicated? An Examination of Sex Differences and Hypothetical Intoxication in Peer Interventions.

    Savage, Matthew W; Menegatos, Lisa; Roberto, Anthony J

    2017-08-01

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

    2015-07-01

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

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

    2006-06-01

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

  10. Distinct kinetics in the frequency of peripheral CD4+ T cells in patients with ulcerative colitis experiencing a flare during treatment with mesalazine or with a herbal preparation of myrrh, chamomile, and coffee charcoal.

    Jost Langhorst

    Full Text Available BACKGROUND: We found the first evidence of the efficacy of a herbal treatment with myrrh, dry extract of chamomile flowers, and coffee charcoal for ulcerative colitis (UC. However, the impact of the herbal treatment on the CD4+ T-cell compartment, which is essential for both the induction of UC and the maintenance of tolerance in the gut, is not well understood. AIM: To analyze the frequency and functional phenotype of CD4+ T cells and of immune-suppressive CD4+CD25high regulatory T cells (Tregs in healthy control subjects, patients with UC in remission, and patients with clinical flare of UC. METHODS: Patients in clinical remission were treated with either mesalazine or the herbal preparation for 12 months. The frequencies of whole CD4+ T cells, CD4+CD25med effector T cells, and Tregs and the expression of Foxp3 within the CD4+CD25hig Tregs were determined by flow cytometry at 6 time points. We determined the suppressive capability of Tregs from healthy control subjects and from patients in remission or clinical flare. RESULTS: A total of 79 patients (42 women, 37 men; mean age, 48.5 years; 38 with clinical flare and 5 healthy control subjects were included in the study. At baseline the frequencies of whole CD4+ T cells, CD4+CD25med effector cells, and Tregs did not differ between the two treatment groups and the healthy control subjects. In addition, patients with UC in sustained clinical remission showed no alteration from baseline after 1, 3, 6, 9, or 12 months of either treatment. In contrast, CD4+ T cells, CD4+CD25med effector T cells, and Tregs demonstrated distinctly different patterns at time points pre-flare and flare. The mesalazine group showed a continuous but not statistically significant increase from baseline to pre-flare and flare (p = ns. In the herbal treatment group, however, the percentage of the CD4+ T cells was lower at pre-flare than at baseline. This decrease was completely reversed after flare, when a significant

  11. New Direction Treatment in Antidote Treatment of OPC Intoxications

    Dishovsky, C.

    2007-01-01

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

  12. CIRCULATORY FAILURE DURING NON-INHALED FORMS OF CYANIDE INTOXICATION

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

  13. Utilization of a Sobering Center for Acute Alcohol Intoxication.

    Smith-Bernardin, Shannon; Carrico, Adam; Max, Wendy; Chapman, Susan

    2017-09-01

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

  14. Driving intoxicated: is hospital admission protective against legal ramifications?

    Cheek, Susannah Mary; Murry, Jason Steven; Truitt, Michael Seth; Dunn, Ernest Lewis

    2013-12-01

    According to the US National Highway Traffic Safety Administration, in 2010, 10,228 people were killed in alcohol-impaired driving crashes. Daily, intoxicated drivers are seen in trauma centers across the country. At our trauma center, we sought to determine the number of drivers who had a documented elevation in their blood alcohol content (BAC) and compare this with county police records to evaluate how many charges for driving while intoxicated (DWI) were issued. A retrospective chart review was performed for trauma admissions during a 3-year period. Patients with a BAC of less than 0.08 g/dL were excluded. Only documented drivers were included. This group of intoxicated drivers was then compared against public records from the Dallas County for any record of a charge of DWI. During a 3-year period, from 2009 to 2011, 118 drivers had a confirmed BAC above the legal limit of 0.08 g/dL. Average BAC level was 0.218 g/dL. Injuries varied widely between patients with an average Injury Severity Score (ISS) of 11. Extremity fractures were seen in 27%, facial fractures were seen in 16%, and intracranial hemorrhage was seen in 7%. Forty-eight percent of the patients were admitted to the intensive care unit initially, with an average length of intensive care unit stay of 1.5 days (range, 0-25 days). Only 18% of our patients (21) received a charge of DWI. Four patients were charge with related offenses. A motor vehicle accident may be protective against the legal ramifications of drinking and driving. Less than 20% of patients who were driving under the influence incurred any legal repercussion. Deterrents that prevent law enforcement from being able to obtain evidence needed for prosecution should be eliminated. Health care providers and law enforcement agencies should work as a team to help mitigate the incidence of drunk driving and its burden on society. Epidemiologic study, level III.

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

  16. Intranasal Fentanyl Intoxication Leading to Diffuse Alveolar Hemorrhage.

    Ruzycki, Shannon; Yarema, Mark; Dunham, Michael; Sadrzadeh, Hossein; Tremblay, Alain

    2016-06-01

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

    1986-01-01

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

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

    It is highly valuable to study the pharmacokinetics of herbal components under the pathological condition of liver dysfunction for safe and rational use of herbal medicines. In this study, the pharmacokinetic profiles of four effective lignans from Schisandra chinensis (SC) , schisandrin, schisantherin A, deoxyshisandrin and γ-schisandrin, were investigated in carbon tetrachloride (CCl 4 )-intoxicated rats. The metabolism of the four lignans was also studied using microsomes from patients with advanced hepatocellular carcinoma. In situ intestinal and hepatic perfusions were conducted to clarify the contributions from impairments of gut and liver on the pharmacokinetics of the four schisandra lignans in CCl 4 -intoxicated rats. The metabolism in rat and human liver microsomes and transport in Caco-2 monolayer cell model were studied to reveal the key factors for the in vivo disposition of the four lignans. When SC alcoholic extract was orally administrated to CCl 4 -intoxicated rat for a short term (4 days), the pharmacokinetics of four active SC lignans was significantly changed while its hepatotherapeutic effect was not obviously observed. The plasma concentrations of the four schisandra lignans were dramatically elevated compared with the control. The Cmax, AUC and MRT were all increased or prolonged significantly while parameter CLz/F was obviously reduced in rat pretreated with CCl 4 . In hepatic perfusion study and liver microsomes incubation, it was found that the hepatic metabolism of the four lignans was markedly decreased mainly due to the activity reduction of multiple CYP450 isoenzymes involved the metabolism, which, eventually, might lead to the alternation of their pharmacokinetic profiles in CCl 4 -intoxicated rats or patients with advanced hepatocellular carcinoma. The pharmacokinetic studies of SC components in pathological situation of liver dysfunction are expected to provide useful data for rational and safe application of SC preparations in

    Oxidative stress is a common pathological condition associated with drug-induced hepatotoxicity. This study investigated Spondias mombin L. aqueous leaf extract on reactive oxygen species and acetaminophen-mediated oxidative onslaught in rats' hepatocytes. Hepatotoxic rats were orally administered with the extract and vitamin C for 4 weeks. The extract dose-dependently scavenged DPPH, hydrogen peroxide and hydroxyl radicals, with IC 50 values of 0.13, 0.66, and 0.64 mg/mL, and corresponding % inhibitions of 89, 80, and 90%, respectively at 1.0 mg/mL. Ferric ion was also significantly reduced. The marked (p<0.05) increases in the activities of alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase were reduced following treatment with the extract. The extract also significantly (p<0.05) induced the activities of antioxidant enzymes. These inductions reversed the acetaminophen-enhanced reduction in the specific activities of these enzymes as well as attenuated the observed elevated concentrations of autooxidized products and rived DNA in the acetaminophen-intoxicated animals. The observed effects competed with those of vitamin C and are suggestive of hepatoprotective and antioxidative attributes of the extract. Overall, the data from the present findings suggest that S. Mombin aqueous leaf extract is capable of ameliorating acetaminophen-mediated oxidative hepatic damage via enhancement of antioxidant defense systems.

  8. Current status of rodenticide intoxication in Brazil: a preliminary survey from 2009 to 2011

    Solange Papini

    2014-10-01

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

    2015-01-01

    Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

    2011-09-01

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

  13. Clinical prognosis of patients with diagnosed chronic solvent intoxication

    Juntunen, J; Antti-Poika, M; Tola, S; Partanen, T

    1982-05-01

    The clinical symptoms and signs of 80 patients with chronic organic solvent intoxication were evaluated after 3-9 years (mean 5.8 years) of follow-up. Thirty-one of the patients had slight clinical neurological signs at the time of diagnosis while the rest of the patients had only neurophysiological or psychological disturbances. The most common subjective symptoms were headache, tiredness and memory disturbances. Of the clinical signs, disturbances occurred frequently in cerebellar functions, gait and station and fine motorics. In addition, psycho-organic alteration and neurasthenic signs were often found. After the follow-up clinical signs of impairment in the nervous system were present in 42 cases. At the group level, the subjective symptoms decreased during the follow-up but the objective clinical signs increased and worsened. Only the prognosis of disturbances in gait and station correlated with the duration and intensity of exposure. The present results emphasize the great difficulties arising in occupational neurology regarding chronic organic solvent intoxications. No clear-cut clinical picture exists and reliable estimation of prognosis in general cannot be made on the basis of the present knowledge.

  14. DO SOBER EYEWITNESSES OUTPERFORM ALCOHOL INTOXICATED EYEWITNESSES IN A LINEUP?

    2013-01-01

    Full Text Available Although alcohol intoxicated eyewitnesses are common, there are only a few studies in the area. The aim of the current study is to investigate how different doses of alcohol affect eyewitness lineup identification performance. The participants (N = 123 were randomly assigned to a 3 [Beverage: control (0.0 g/kg ethanol vs. lower (0.4 g/kg ethanol vs. higher alcohol dose (0.7 g/kg ethanol] X 2 (Lineup: target-present vs. target-absent between-subject design. Participants consumed two glasses of beverage at an even pace for 15 minutes. Five minutes after consumption the participants witnessed a film depicting a staged kidnapping. Seven days later, the participants returned to the laboratory and were asked to identify the culprit in a simultaneous lineup. The result showed that overall, the participants performed better than chance; however, their lineup performance was poor. There were no significant effects of alcohol intoxication with respect to performance, neither in target-present nor target-absent lineups. The study’s results suggest that eyewitnesses who have consumed a lower (0.4 g/kg ethanol or a higher (0.7 g/kg ethanol dose of alcohol perform at the same level as sober eyewitnesses in a lineup. The results are discussed in relation to the alcohol myopia theory and suggestions for future research are made.

    Aprahamian, A; Escoda, S; Patteau, G; Merckx, A; Chéron, G

    2011-12-01

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

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

    Larpin, R; Vincent, A; Perret, C

    1990-09-22

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

    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. 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. 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. In conclusion subchronic intoxication with lambda cyhalothrin formulation induced remarkable changes in the examined parameters.

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

  19. The delphic oracle and the ethylene-intoxication hypothesis.

    Foster, J; Lehoux, D

    2007-01-01

    An interdisciplinary team of scientists--including an archeologist, a geologist, a chemist, and a toxicologist--has argued that ethylene intoxication was the probable cause of the High Priestess of Delphi's divinatory (mantic) trances. The claim that the High Priestess of Delphi entered a mantic state because of ethylene intoxication enjoyed widespread reception in specialist academic journals, science magazines, and newspapers. This article uses a similar interdisciplinary approach to show that this hypothesis is implausible since it is based on problematic scientific and textual evidence, as well as a fallacious argument. The main issue raised by this counterargument is not that a particular scientific hypothesis or conjecture turned out to be false. (This is expected in scientific investigation.) Rather, the main issue is that it was a positivist disposition that originally led readers to associate the evidence presented in such a way that it seemed to point to the conclusion, even when the evidence did not support the conclusion. We conclude by observing that positivist dispositions can lead to the acceptance of claims because they have a scientific form, not because they are grounded in robust evidence and sound argument.

    2013-05-01

    Full Text Available Background: Carnitine transports fatty acids from the cytoplasm to the mitochondrial matrix, where the fatty acids are oxidized. Chronic alcohol consumption reduces the concentration of carnitine and interferes with oxidative processes occurring in the cell.Aim: The assessment of carnitine concentrations in plasma of chronically intoxicated alcohol dependent persons in a 49-day abstinence period.Material/Methods: The study included 31 patients (5 women and 27 men aged from 26 to 60 years (44.6± 8.9 and 32 healthy subjects (15 women and 17 men aged 22-60 years (39.8± 9.4. The patients’ alcohol dependence ranged from 2 to 30 years (13.6± 7.5. Examined subjects consumed 75-700 g of ethanol/day (226.9± 151.5. Plasma concentrations of free and total carnitine were measured three times: at the first (T0, 30th (T30 and 49th (T49 day of hospital detoxification. Free (FC and total (TC carnitine were determined by the spectrophotometric method. Plasma acylcarnitine (AC concentration was calculated from the difference between TC and FC; then the AC/FC ratio was calculated. To determine statistically significant differences for related variables, Student’s t-test was used.Results: At T0, alcoholics had significantly lower concentration of FC and TC (p < 0.05 in plasma, as compared to the control group. In comparison to controls, at T30, plasma TC and FC (p < 0.01 as well as AC (p < 0.001 were reduced. The lowest concentration of TC, FC and AC (p < 0.001was found at T49. The ratio of AC/FC at T0 had a tendency to be higher in alcoholics than in the control group (p = 0.05, whereas at T49 it was significantly lower in alcoholics as compared to the control subjects (p < 0.05.Conclusions: Chronic alcohol intoxication causes a plasma deficiency of carnitine. Forty-nine days of abstinence showed a significant decrease in the concentration of TC, FC and AC. Further research is necessary to clarify whether a low level of plasma carnitine

    A. A. Baranov

    2015-01-01

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

  4. [Carbohydrates metabolism disturbances when simulating prenatal alcohol intoxication].

    Kurch, N M; Vysokogorskiĭ, V E

    2013-01-01

    The influence of prenatal alcohol intoxication on carbohydrate metabolism markers has been investigated at different terms of postnatal offspring development (15, 30 and 60 days). Plasma glucose decreased as compared with the same in control group was detected. In the liver homogenates an increase of phosphorylase activity and a decrease of glucose-6-phosphatase, aldolase and glucose-6-phosphate dehydrogenase activities were found. These changes were accompanied by the incease in the lactate/pyruvate index attributed to increased lactate content in the liver tissue. The obtained data indicate essential disturbances of carbohydrate metabolism markers in prenatal alcoholized offspring, which include stable hypoglycemia, suppression of glycolytic and pentosephosphate pathways of glucose metabolism and lactate accumulation in the liver.

    Dokter, M; Talarico, G; Armbrust, S; Below, E; Bockholdt, B

    2018-05-01

    A 17-year-old girl was found vomiting and somnolent at home and was taken to a hospital. The girl initially presented with ventricular tachycardia with broad QRS complexes which was very difficult to control. During the course a subsequent cardiogenic shock developed and despite exhaustion of all therapeutic options the fatal outcome could not be averted. The medicolegal autopsy revealed no evidence of any form of violence but the signs of medical treatment. Furthermore, no pathology of internal organs was detected. The toxicological analyses revealed a lethal intoxication with flecainide as the cause of death. The investigations of the police indicated that the girl took flecainide in suicidal intention.

  6. Salicylate removal by charcoal heamoperfusion in experimental intoxication in dogs

    Brookings, C.H.; Ramsey, J.D.

    1975-01-01

    The removal of salicylate by extracorporeal circulation of blood through a column of encapsulated charcoal (haemoperfusion) has been studied experimentally in intoxicated dogs (greyhounds). The average time taken to reduce the whole blood salicylate level to one-half of the initial equilibrium level in 30 kg dogs was 2 hrs. A half-life of 3 hrs is predicted for salicylate removal by haemoperfusion in a 70 kg man and this rate of removal is shown to be comparable to that reported for haemodialysis. No unacceptable adverse physiological, biochemical, or haematological effects were found to result from haemoperfusion. The possible use of this technique in the management of severe salicylate poisoning in man is discussed. Haemoperfusion is foreseen as providing a method of rapid removal of salicylate in circumstances where forced diuresis is contra-indicated or inadequate and haemodialysis is not readily available.

  7. Magnetic Resonance Imaging Findings in Chronic Carbon Monoxide Intoxication

    Durak, A. C.; Coskun, A.; Yikilmaz, A.; Erdogan, F.; Mavili, E.; Guven, M. [Hospital of Erciyes Univ., Kayseri (Turkey). Dept. of Radiology

    2005-05-01

    Purpose: To define the cranial magnetic resonance imaging (MRI) features of the chronic stage of carbon monoxide (CO) poisoning in patients with and without neuropsychiatric sequelae. Material and Methods: Eight patients who had neither symptoms nor neurological sequelae and eight patients with neuropsychiatric sequelae were included in the study. Patients aged between 9 to 57 (mean 32.2 years). All patients had been comatose at initial admittance and awoke after normobaric 100% oxygen therapy within 1-7 days. In this study, the patients were being examined with routine cranial MRI between 1 and 10 years (mean 3.4 years) after exposure to CO. Results: The most common finding was bilateral symmetric hyperintensity of the white matter, which was more significant in the centrum semiovale, with relative sparing of the temporal lobes and anterior parts of the frontal lobes on T2-weighted and FLAIR images in all patients. Cerebral cortical atrophy was seen in 10 patients; mild atrophy of cerebellar hemispheres in 8; and vermian atrophy in 11. Corpus callosum was atrophic in one patient. Bilateral globus pallidus lesions were seen in three patients. The lesions were hypointense on T1-weighted images and hyperintense on T2-weighted and FLAIR images. Conclusion: Patients with severe CO intoxication may develop persistent cerebral changes independently of their neuropsychiatric findings in the chronic stage. They may present with characteristic MRI findings as described here, even if asymptomatic. The history of CO exposure is therefore helpful for recognizing and interpreting the MRI findings of chronic stage CO intoxication.

    Polański, Piotr; Ostrek, Joanna; Sadkowska-Todys, Małgorzata

    2015-01-01

    The purpose of the study is to assess the epidemiological situation of food poisonings and infections in Poland in 2013. The evaluation was based on the analysis of information from reports of epidemiological investigations in outbreaks of food poisonings and infections, submitted by the sanitary-epidemiological stations to the Department of Epidemiology, NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2006-2013. Warsaw, NIPH-NIH and GIS). In 2013 a further decrease in the number of infections and intoxications with bacterial etiology and an increase in the infections of viral etiology was observed. Furthermore 2013 is another year with low number of cases of trichinellosis (9 cases in total). In 2013 a total number of 491 foodborne infections and intoxications outbreaks were reported in which there were 29,179 persons exposed and 5,664 (including 2 193 children up to 14 years of age) persons ill. Hospitalization was required for 1,445 persons. The most frequent etiological agent in those outbreaks was Salmonella spp.--which was responsible for 36,3% of outbreaks and 21,5% of cases. Viruses were responsible for 29,7 of outbreaks and 45,7 cases, in 19,3% of outbreaks no etiological agent was established. Like in 2012 the most frequent vehicle were dishes made from eggs and milk combined with eggs (9,4% of outbreaks). In 65% of outbreaks reported no vehicle could be found. Moreover in 2013 a total number of 3 outbreaks in which more than 100 cases were reported. The increase in the number of foodborne outbreaks of viral etiology shows the need of adjustment some aspects of epidemiological investigations especially such features as: laboratory conformation of etiological agent of ill persons as well as persons involved in the food processing and meals preparing and the aspect of food samples testing.

    The purpose of the study is to assess the epidemiological situation of foodborne infections and intoxications in Poland in 2012. The evaluation was based on analysis of information from reports of epidemiological investigations in foodborne outbreaks, submitted by the sanitary-epidemiological stations to the Department of Epidemiology, NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2006-2012. Warsaw, NIPH-NIH and CSI). In Poland in 2012 there was observed decrease in the number of infections intoxications both of bacterial and viral origin. It was recorded only one case of trichinellosis. There were reported 491 outbreaks of foodborne poisonings or infections included 5 774 people, among them 718 children 1-14 years old. Out of them 1 364 people were hospitalized. Unlike last year, the predominant etiological agent in those outbreaks were zoonotic Salmonella serotypes which caused 38.1% outbreaks and 26.7% outbreak cases. The viruses have caused 27.1% of outbreaks and 36.2% of cases. In 23.8% of outbreaks etiological agent has not been established. Most often the settings of an outbreak was a private household - 236 outbreaks and a hospital (84 outbreaks). As in previous years, the most common vehicle of infection were foods prepared with milk and eggs -11.8% of outbreaks and egg dishes - 9.0%. In 57.6% of oubreaks vehicle of infection has not been established. Among outbreaks reported in 2012, there were 4 which involved more than 100 people. In 163 outbreaks of food items had been tested and in 33% of them the results were positive. The increasing negative results of bacteriological examinations of food items, suggested necessity to start testing food contamination with viruses.

    2006-01-01

    Full Text Available The present study was designed to evaluate the time course changes in peripheral markers of oxidative stress in a chronic HgCl2 intoxication model. Twenty male adult Wistar rats were treated subcutaneously daily for 30 days and divided into two groups of 10 animals each: Hg, which received HgCl2 (0.16 mg kg-1 day-1, and control, receiving the same volume of saline solution. Blood was collected at the first, second and fourth weeks of Hg administration to evaluate lipid peroxidation (LPO, total radical trapping antioxidant potential (TRAP, and superoxide dismutase (Cu,Zn-SOD, glutathione peroxidase (GPx, glutathione-S-transferase (GST, and catalase (CAT. HgCl2 administration induced a rise (by 26% in LPO compared to control (143 ± 10 cps/mg hemoglobin in the second week and no difference was found at the end of the treatment. At that time, GST and GPx were higher (14 and 24%, respectively in the Hg group, and Cu,Zn-SOD was lower (54% compared to control. At the end of the treatment, Cu,Zn-SOD and CAT were higher (43 and 10%, respectively in the Hg group compared to control (4.6 ± 0.3 U/mg protein; 37 ± 0.9 pmol/mg protein, respectively. TRAP was lower (69% in the first week compared to control (43.8 ± 1.9 mM Trolox. These data provide evidence that HgCl2 administration is accompanied by systemic oxidative damage in the initial phase of the process, which leads to adaptive changes in the antioxidant reserve, thus decreasing the oxidative injury at the end of 30 days of HgCl2 administration. These results suggest that a preventive treatment with antioxidants would help to avoid oxidative damage in subjects with chronic intoxication.

  11. An overview of exposure to ethanol-containing substances and ethanol intoxication in children based on three illustrated cases

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

    2011-02-01

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

    Weijters, B J; Verbunt, R J A M; Hoogsteen, J; Visser, R F

    2008-01-01

    Intoxication with Aconitum napellus is rare in our regions. Aconite alkaloids can cause ventricular arrhythmia by a prolonged activation of sodium channels. Because the margin of safety is low between the analgesic and toxic dose, intoxication is not rare when Aconite is used in herbal medicine. We present a case in which a 39-year-old male was accidentally intoxicated with Aconite. Even though no antidote or adequate therapy is available he was successfully resuscitated. (Neth Heart J 2008;16:96-9.).

  14. EFFECTS OF THE LITHIUM – CONTAINING SORBENT ON TERMS OF BEHAVIORAL REACTIONS UNDER CHRONIC ALCOHOL INTOXICATION MODEL

    A. A. Kotlyarova

    2016-01-01

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

  15. Lead intoxication in dogs: risk assessment of feeding dogs trimmings of lead-shot game.

    2016-07-25

    Expanding lead-based bullets, commonly used for hunting of big game, produce a scattering of lead particles in the carcass around the wound channel. Trimmings around this channel, which are sometimes fed to dogs, may contain lead particles. The aim of this study was to assess potential health effects of feeding dogs such trimmings. Lead ingestion most commonly causes gastrointestinal and neurological clinical signs, although renal, skeletal, haematological, cardiovascular and biochemical effects have also been reported. Experimental data indicate that a daily dose of around 1 mg lead as lead acetate/kg body weight for ten days may be considered as a Lowest Observed Effect Level in dogs. Acute toxicity documentation from the Centers for Disease Control and Prevention indicates 300 mg/kg body weight as the lowest dose of lead acetate causing death in dogs after oral ingestion. Our assessment suggests that dogs fed trimmings of lead-shot game may be affected by the amounts of lead present, and that even deadly exposure could occasionally occur. The intestinal absorption of lead from bullets was assumed to be 10-80 % of that of lead acetate, reflecting both the variability in particle size and uncertainty about the bioavailability of metallic lead in dogs. Despite data gaps, this study indicates that feeding dogs trimmings of lead-shot game may represent a risk of lead intoxication. More research is needed to assess the exact consequences, if lead-based bullets are still to be used. Meanwhile, we recommend that trimmings close to the wound channel should be made inaccessible to dogs, as well as to other domestic or wild animals.

  18. Delayed Encephalopathy of Carbon Monoxide Intoxication and Treatment with Hyperbaric Oxygen: A Case Report

    Fatma Polat

    2012-09-01

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

    2016-06-01

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

    Clinical judgement of intoxicated patients is difficult. In the emergency department of the inner city of Oslo this is done every day. During a one-year period from 1998-99, a group of 429 first-time admitted intoxicated patients were included in a study. The patients and the method of observation are described. 75% of the patients were men; 45% reported to have consumed alcohol only, while 10% had taken a heroin overdose. The rest had used various combinations of legal and illegal drugs. Female patients were younger than male patients (29 versus 36 years, p intoxicated only on alcohol were on the average older than patients who had taken drugs (38 versus 31 years, p intoxicated patients.

  1. Ultrastructural changes in the liver following chronic experimental intoxication with benzine and ethyline vapor

    Jonek, J.; Przybylowski, J.; Gryzbek, H.; Podolecki, A.; Pacholek, A.

    1978-01-01

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

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

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

  8. Pathophysiological Features of Endogenous Intoxication in Pregnant Women with Arterial Hypertension

    N. V. Kabanova

    2008-01-01

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

    Matos, Tomás D; Robles, Rafaela R; Sahai, Hardeo; Colón, Hector M; Reyes, Juan C; Marrero, C Amalia; Calderón, José M; Shepard, Elizabeth W

    2004-12-07

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

  10. Intoxication due to Papaver rhoeas (Corn Poppy: Five Case Reports

    Yahya Kemal Günaydın

    2015-01-01

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

  13. Acute interstitial nephritis with acetaminophen and alcohol intoxication

    Alexopoulou Iakovina

    2011-04-01

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

  14. Effectiveness of chelation therapy with time after acute uranium intoxication

    Domingo, J.L.; Ortega, A.; Llobet, J.M.; Corbella, J.

    1990-01-01

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

  15. Bath salt intoxication causing acute kidney injury requiring hemodialysis.

    Regunath, Hariharan; Ariyamuthu, Venkatesh Kumar; Dalal, Pranavkumar; Misra, Madhukar

    2012-10-01

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

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

    Seventeen East-European workers with a suspected lead-intoxication presented themselves to the Department of Toxicology. All of them had worked on the renovation of pylons of a high-tension line. The old paint, known to contain lead was removed with needle descalers. The patients had blood lead concentrations between 325 and 1124 microg/l, but no specific symptoms. The workers neglected the protective measures at their working-place. 12 of 17 workers had lead-concentrations above 400 microg/l (Reference lead-concentration above 700 microg/l were treated with the chelating agent meso-2,3-dimercaptosuccinic acid (DMSA) 3 x 200 mg/d for nine days. The patients with lead concentrations between 400 and 700 microg/l were treated which DMSA 3 x 100 mg/d. After the DMSA-treatment the lead-concentrations had dropped (p lead concentration in their blood due to occupational exposure. The high blood lead levels showed that the workers had not been protected adequately. This examplifies that occupational lead exposure still occurs, also in Germany. By patients with unspecific symptoms connected with lead exposure a biomonitoring for lead is necessary.

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

    The idea of identifying oral lesions with a precancerous nature, i.e. in the sense of pertaining to a pathologic process with an increased risk for future malignant development, of course is to prevent frank malignancy to occur in the affected area. The most common oral lesion with a precancerous...... nature is oral leukoplakia, and for decades it has been discussed how to treat these lesions. Various treatment modalities, such as systemic therapies and surgical removal, have been suggested. The systemic therapies tested so far include retinoids, extracts of green tea, inhibitors of cyclooxygenase-2...

  1. Can Intoxication Status Be Used as a Prediction Tool for Manner of Death?: A Comparison of the Intoxication Status in Violent Suicides and Homicides.

    Molina, D Kimberley; Hargrove, Veronica M

    2017-03-01

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

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

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

    2014-04-01

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

  5. Overserving and Allowed Entry of Obviously Alcohol-Intoxicated Spectators at Sporting Events.

    2018-02-01

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

  6. Oral cancer.

    Gerson, S J

    1990-01-01

    In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

    The Gay and Lesbian Medical Association urges HIV prevention specialists to regard male-to-male oral-genital sex as a low-risk activity and concentrate instead on the danger of unprotected anal intercourse. According to the association, the confusion and mixed messages surrounding oral sex are harming efforts to encourage gay men to make rational choices about truly risky behavior. The recommendations appear in the association's position paper issued March 19, 1996.

  9. The effect of lead intoxication on endocrine functions.

    Doumouchtsis, K K; Doumouchtsis, S K; Doumouchtsis, E K; Perrea, D N

    2009-02-01

    Studies on the effects of lead on the endocrine system are mainly based on occupationally lead-exposed workers and experimental animal models. Although evidence is conflicting, it has been reported that accumulation of lead affects the majority of the endocrine glands. In particular, it appears to have an effect on the hypothalamic-pituitary axis causing blunted TSH, GH, and FSH/LH responses to TRH, GHRH, and GnRH stimulation, respectively. Suppressed GH release has been reported, probably caused by reduced synthesis of GHRH, inhibition of GHRH release or reduced somatotrope responsiveness. Higher levels of PRL in lead intoxication have been reported. In short-term lead-exposed individuals, high LH and FSH levels are usually associated to normal testosterone concentrations, whereas in long-term exposed individuals' low testosterone levels do not induce high LH and FSH concentrations. These findings suggest that lead initially causes some subclinical testicular damage, followed by hypothalamic or pituitary disturbance when longer periods of exposure take place. Similarly, lead accumulates in granulosa cells of the ovary, causing delays in growth and pubertal development and reduced fertility in females. In the parenchyma of adrenals histological and cytological changes are demonstrated, causing changes in plasma basal and stress-mediated corticosterone concentrations and reduced cytosolic and nuclear glucocorticoid receptor binding. Thyroid hormone kinetics are also affected. Central defect of the thyroid axis or an alteration in T4 metabolism or binding to proteins may be involved in derangements in thyroid hormone action. Lead toxicity involves alterations on calcitropic hormones' homeostasis, which increase the risk of skeletal disorders.

    2006-04-01

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

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

    Yang Hu

    2018-01-01

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

  12. Inhibition of renal Na+/H+ exchange in cadmium-intoxicated rats

    2005-01-01

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

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

    Combined toxicity of lead and fluoride has been studied insufficiently, and there is no known information about attempts to inhibit it with any bioprotectors. Lead acetate and sodium fluoride, administered separately or in combination, were injected i.p. to rats at isoeffective sublethal doses 3 times a week for 6 weeks. Some of the rats were exposed to the same combination against the background of oral administration of a bioprotector complex (BPC) comprising pectin, glutamate, and multivitamin/multimineral preparations. Following exposure, functional and biochemical indices and histopathological examinations of the femur of exposed and control rats were evaluated for signs of toxicity. We have shown that with regard to a number of effects on the organism level the combined toxicity of lead and fluoride may be evaluated as additive or even superadditive, but lead reduces fluoride accumulation in the bone, and pathological changes in the bone tissue proved to be less marked for combined exposure compared with separate exposures. The BPC has been demonstrated to attenuate a range of the combined harmful effects of lead and fluoride, including those on the bone tissue. In spite of the fact that fluoride and lead may reciprocally attenuate their harmful effects on the bone tissue in case of combined exposure, they prove to be more toxic for soft tissues just in combination than when administered separately. The development of combined intoxication may be substantially inhibited by means of the tested set of innocuous biologically active agents.

  15. Differential diagnosis between secondary hyperparathyroidism and aluminum intoxication in uremic patients: Usefulness of 99mTc-pyrophosphate bone scintigraphy

    Kinnaert, P.; Van Hooff, I.; Schoutens, A.

    1989-01-01

    Forty-one patients in chronic end-stage renal failure and 4 patients with a functioning kidney transplant presented with spontaneous hypercalcemia or intolerance to vitamin D3 sterols and/or oral calcium supplements. Bone iliac crest biopsy with aluminum staining and Tc-pyrophosphate bone scintigraphy with determination of Fogelman score were performed in all cases. Two patients had aluminum-induced osteomalacia (AL O). Thirty-eight biopsies showed renal osteodystrophy (secondary hyperparathyroidism or various combinations of osteitis fibrosa and osteomalacia): 19 with positive staining for aluminum (RO + AL) and 19 without aluminum deposits (RO). The series also comprised 2 cases of pure osteomalacia (OM), 2 cases of osteoporosis (OP), and 1 case of osteoporosis with aluminum accumulation (OP + AL). Mean Fogelman score in RO patients (9.1 +/- 0.3) was significantly higher than in all other categories (5.9 +/- 0.5 for RO + AL, and scores ranging from 0 to 8 in the last 7 patients, p less than 0.01). Patients with massive aluminum accumulation in bone (greater than 75% of the total trabecular surface) showed no or very low uptake of the isotope by the skeleton. Fogelman scores of 9 or higher were always associated with histological secondary hyperparathyroidism. 99m Tc-pyrophosphate bone scintigraphy is helpful to distinguish aluminum intoxication from secondary hyperparathyroidism in uremic patients

  16. A Case Report of Successful Kidney Donation After Brain Death Following Nicotine Intoxication.

    Räsänen, M; Helanterä, I; Kalliomäki, J; Savikko, J; Parry, M; Lempinen, M

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

    Schnuelle Peter

    2006-04-01

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

  18. The benzodiazepine/GABA receptor complex during severe ethanol intoxication and withdrawal in the rat

    Hemmingsen, R.; Braestrup, C.; Nielsen, M.; Barry, D.I.

    1982-01-01

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

  19. Investigating global trends in paraquat intoxication research from 1962 to 2015 using bibliometric analysis.

    Zyoud, Sa'ed H

    2018-06-01

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

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

  2. Oral candidiasis.

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

    2010-01-01

    Full Text Available Myiasis is a relatively rare condition arising from the invasion of body tissues or cavities of living animals or humans by maggots or larvae of certain species of flies. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions; alcoholism and senility. Its diagnosis is made basically by the presence of larvae. The present article reports a case of oral myiasis involving 20 larvae in a patient with neurological deficiency.

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

    2016-02-01

    Conclusions. Comprehensive assessment of integral indices of endogenous intoxication and level of certain pro- and anti-inflammatory cytokines in the blood plasma of patients with MDR TB shows a moderate endogenous intoxication, break down of the cellular component of the immune reactivity due to the formation of conditions for the development of Mycobacterium tuberculosis resistance, with further growth of cytotoxic hypoxia and activation of systemic inflammatory response syndrome. Analysis of plasma concentration of IL-6, IL-10 and IL-18 in patients with multidrug-resistance proved, that their level depends on the nature of Mycobacterium tuberculosis resistance.

  10. Hepatic mitochondrial and microsomal recovery of rats intoxicated with CCl/sub 4/

    Hasegawa, T.; Hirai, Y.; Koga, N.; Tomokuni, K.

    1983-01-01

    The hepatic mitochondrial and microsomal recovery of rats intoxicated with CCl/sub 4/ was investigated with specific reference to the oxygen utilization of liver slices. In control rats, the major oxygen utilization of the liver slices was attributed to mitochondrial particles. Since the mitochondrial oxygen utilization was inhibited by cyanide, the microsomal oxygen utilization was induced by NADPH and phenobarbital (a substrate for microsomal mixed function oxidase). Changes in oxygen utilization were observed in the recovery course of rats intoxicated with CCl/sub 4/, and the recovery of mitochondria was found to be faster than that of microsomes. A sex difference was present in the recovery mechanism of the microsomes.

  12. Effects of Lead Intoxication on Intervertebral Disc (Experimental Study

    V.Ye. Maltseva

    2012-02-01

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

  13. Oral calcitonin

    2012-09-01

    Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

    Till date, drugs that have been used to manage Parkinson's disease (PD) have only shown symptomatic relief with several adverse effects besides their inability to prevent neurodegeneration. Neuroinflammation plays an important role in the advancement of PD and can be targeted for its effective treatment. Researchers have suggested that herbal plants exhibiting the anti-inflammatory and anti-oxidant properties are therefore beneficial to human health. Conventionally, Mucuna pruriens (Mp) seeds are used for maintaining male virility in India. Reportedly, Mp is used as a rejuvenator drug having neuroprotective property. Our study aimed to investigate effects of aqueous extract of Mp (100 mg/kgbwt) on neuroinflammation, orally administered to mice intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) as well as the molecular mechanism involved in the progression of PD. In this study, we have observed significant behavioral abnormalities beside decreased antioxidant defense in MPTP intoxicated mice. We have also observed significant increase in inflammatory parameters like Glial Fibrillary Acidic Protein, Inducible Nitric Oxide Synthase, Intercellular Cell Adhesion Molecule, and Tumor Necrosis Factor alpha in substantia nigra pars compacta (SNpc) of parkinsonian mice, while Mp treatment has notably reduced these inflammatory parameters. Mp also inhibited the MPTP induced activation of NF-κB and promoted pAkt1 activity which further prevented the apoptosis of the dopaminergic neurons. Moreover, Mp exhibited significant antioxidant defense by inhibiting the lipid peroxidation and nitrite level, and by improving catalase activity and enhancing GSH level in nigrostriatal region of mouse brain. Mp also recovered the behavioral abnormalities in MPTP treated mice. Additionally, Mp treatment considerably increased the immunoreactivity of Tyrosine Hydroxylase and Dopamine Transporter in SNpc of parkinsonian mice. Our high performance liquid chromatography

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

  16. Experimental lead intoxication in dogs: a comparison of blood lead and urinary delta-aminolevulinic acid following intoxication and chelation therapy.

    Green, R A; Selby, L A; Zumwalt, R W

    1978-01-01

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

  17. Oral care.

    Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. Copyright © 2011 S. Karger AG, Basel.

  19. Four Intoxication Cases Related to the Misuse of Sage Oil

    Suzan Gündüz

    2016-06-01

    Full Text Available Infantile colic is excessive crying of infants younger than 4 months. Families of children suffering from infantile colic attend to the emergency department frequently and the etiology is not well-known. However many families of chil­dren suffering from infantile colic try pharmacologic and non-pharmacologic treatment, they are sleepless and ex­hausted and are affected negatively. Sage oil is in volatile form and it is recommended to apply 1-2 drops on plantar and tummy region of the body by massage for the treat­ment of infantile colic. Most of drugs used for infantile colic are drops and used orally. Families who do not learn detailed usage information may use it orally or may pre­sumed another drug while suffering from sleepless and drowsiness. Herein we reported 4 cases of sage oil intoxi­cation because of wrong information of wrong application of sage oil. We aimed to reduce the prescribing of sage oil in the treatment of infantile colic and emphasize to give more information about proper use of sage oil.

  3. Are restrained eaters accurate monitors of their intoxication? Results from a field experiment.

    Buchholz, Laura J; Crowther, Janis H; Olds, R Scott; Smith, Kathryn E; Ridolfi, Danielle R

    2013-04-01

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

    2014-12-01

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

    2007-07-01

    Full Text Available This study reported on the possibility of intoxications of non-target wild animalsassociated with use of bromadiolone as the active component of rodenticides withanticoagulation effects. A laboratory test was done with earthworms were exposed tobromadiolone-containing granules under the conditions specified in the modified OECD207 guideline. No mortality of earthworms was observed during the fourteen days longexposure. When the earthworms from the above test became a part of the diet of commonvoles in the following experiment, no mortality of consumers was observed too. However,electrochemical analysis revealed higher levels of bromadiolone in tissues fromearthworms as well as common voles compared to control animals. There were determinedcomparable levels of bromadiolone in the liver tissue of common voles after primary(2.34±0.10 μg/g and secondary (2.20±0.53 μg/g intoxication. Therefore, the risk ofsecondary intoxication of small mammalian species feeding on bromadiolone-containing earthworms is the same as of primary intoxication through baited granules. Bromadiolone bio-accumulation in the food chain was monitored using the newly developed analytical procedure based on the use of a liquid chromatography coupled with electrochemical detector (HPLC-ED. The HPLC-ED method allowed to determine the levels of bromadiolone in biological samples and is therefore suitable for examining the environmental hazards of this substance.

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

  8. Ricinus communis intoxications in human and veterinary medicine-a summary of real cases.

    Worbs, Sylvia; Köhler, Kernt; Pauly, Diana; Avondet, Marc-André; Schaer, Martin; Dorner, Martin B; Dorner, Brigitte G

    2011-10-01

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

  9. Women's condom use assertiveness and sexual risk-taking: effects of alcohol intoxication and adult victimization.

    Stoner, Susan A; Norris, Jeanette; George, William H; Morrison, Diane M; Zawacki, Tina; Davis, Kelly Cue; Hessler, Danielle M

    2008-09-01

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

The intentional and episodic use of large amounts of psychoactive substances by adolescents is a usual occurrence, and unintentional intoxication is more common in children younger than 12 years. The clinical picture in adolescents and children differs from that in adults and some particularities are important in the emergency scenario. After management of the acute condition, interventions targeting the adolescent at risk may be effective. Conclusion: The diagnosis and treatment of intoxication by alcohol and other drugs in adolescents and children in the emergency scenario requires a systematic evaluation of the use of these drugs. There are few specific treatments for intoxication, and the management comprehends support measures and management of related clinical complications.

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

    Lead intoxication is a worldwide health problem which frequently affects the kidney. In this work, we studied the effects of chronic lead intoxication (500 ppm of Pb in drinking water during seven months) on the structure, function and biochemical properties of rat proximal tubule cells. Lead-exposed animals showed increased lead concentration in kidney, reduction of calcium and amino acids uptake, oxidative damage and glucosuria, proteinuria, hematuria and reduced urinary pH. These biochemical and physiological alterations were related to striking morphological modifications in the structure of tubule epithelial cells and in the morphology of their mitochondria, nuclei, lysosomes, basal and apical membranes. Interestingly, in addition to the nuclei, inclusion bodies were found in the cytoplasm and in mitochondria. The epithelial cell structure modifications included an early loss of the apical microvillae, followed by a decrement of the luminal space and the respective apposition and proximity of apical membranes, resulting in the formation of atypical intercellular contacts and adhesion structures. Similar but less marked alterations were observed in subacute lead intoxication as well. Our work contributes in the understanding of the physiopathology of lead intoxication on the structure of renal tubular epithelial cell-cell contacts in vivo.

  16. Physiologic effects of prolonged conducted electrical weapon discharge in ethanol-intoxicated adults.

    Moscati, Ronald; Ho, Jeffrey D; Dawes, Donald M; Miner, James R

    2010-06-01

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

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

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

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

    Colloff, Melissa F; Flowe, Heather D

    2016-06-01

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

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

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

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

    Stock, Ann-Kathrin; Schulz, Tom; Lenhardt, Martin; Blaszkewicz, Meinolf; Beste, Christian

    2016-01-01

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

  8. Lead intoxication: a summary of the clinical presentation among Thai patients.

    2006-08-01

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

    2002-08-01

    circumstances. RESULTS: in Brazil, there were 151.000 intoxication cases in the focused period. Almost one third was associated to medication, and about forty thousand occurred among children less than five years old. Analgesics, the decongestants, the bronchodilators, the antiepileptics and oral contraceptives were the therapeutic classes involved, and the decongestants, the antiepileptics, the antihistamines and the expectorants were associated to cause of death. The surveillance system pointed out that individual accidents, medication errors and therapeutic misuse were the main circumstances involved. CONCLUSIONS: drug intoxication is a major public health problem, for which intervention measures are necessary. Educational and regulatory actions could decrease the number of accidents and injuries. The main inadequacies of SINITOX are under-registration, lack of integration with health services and poor data uniformity.

  10. [The "dental amalgam syndrome" - an environmental somatization Syndrome? A comparison between chronic carbon monoxide intoxication and illness related to dental amalgam].

    Leonhardt, T

    2001-01-01

    In 1940, during World War II, restrictions in import of petroleum products to Sweden necessitated the use of producer gas in motor traffic. In the following years, the incidence of acute carbon monoxide intoxications raised steeply. However, many patients with minor but longstanding exposition to producer gas exhibited a neurastenic syndrome (fatigue, headaches and vertigo) thought to be specific. In Stockholm, an epidemic of this syndrome can afterwards be traced to the personal conviction of an internist who also had an important influence on various authorities, leading to a forceful campaign to the public about the dangers of using producer gas. After some years, the frequency and even the existence of a chronic carbon monoxide intoxication was called in question and at the end of the war that diagnosis lost its actuality. In Sweden, oral galvanism attributed to dental amalgam was discussed in mass media in the 1970s, not least by evidence given by some well-known personalities. In the 1980s, the frequency of illness attributed to dental amalgam increased to an important epidemic. The question of the dangers of mercury released from amalgam fillings is still an important issue of debate among dentists and physicians, although the majority remains sceptical. Also medical authorities have found little evidence of the importance of dental amalgam toxicity. A patients organisation, Tandvårdsskadeförbundet, seems to have played a significant part in the acceptance of the syndrome among laymen. Thus, various psychosocial factors seem to have played a role in both syndromes which could thus be conceived as environmental somatization syndromes.

  12. Cardiac Arrest After Status Epilepticus: Bupropion and Ecstasy Intoxication

    Zübeyde Tuba Duran

    2018-04-01

    Full Text Available Bupropion is a monocyclic antidepressant that has been known to cause seizures in high therapeutic doses or acute high doses. Bupropion is a selective norepinephrine, dopamine and minimally serotonin reuptake inhibitor. Overdose of bupropion may lead to recurrent seizures, hypoxia and death. It is important to be aware in terms of bradycardia-asystole as a significant consequence of seizure and hypoxia. Patients using high dose of bupropion should be closely monitored in terms of cardiological and neurological. In this study, we presented a 19 year-old female patient who did not have previous history of epilepsy but who used oral bupropion to reduce nicotine addiction. A status epilepticus and cardiac arrest developed in a case receiving 1,8 g bupropion for suicide. 3.4-methylenedioxy-N-methylamphetamine (MDMA and benzodiazepine were detected in urine sample. We did not find any cases in the literature related to MDMA and bupropion overdose. Therefore, we presented this rare case.

  15. Characterization of the psychological, physiological and EEG profile of acute betel quid intoxication in naïve subjects.

    Peter G Osborne

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

Accordingly, patients admitted to hospital from fire accidents may have been exposed to both HCN and CO. Cyanide (CN) intoxication results in cytotoxic hypoxia leading to organ dysfunction...... and animal experiments have shown that in rats exposed to CN intoxication, HBO can increase the concentration of CN in whole blood....

    The incorporation of DL-methionine /sup 3/H into the rat brain in the course of acute edema caused by the triethyl tin sulphate (TET) was investigated by autoradiography. The results indicate that TET intoxication effects in lower incorporation of methionine into the experimental rat brain in comparison to that in normal animals. The changes in dynamics of DL-methionine /sup 3/H incorporation after TET intoxication are presented. The possible pathogenetic mechanism of the observed changes is discussed.

  18. Fetal brain damage following maternal carbon monoxide intoxication: an experimental study

    Ginsberg, M D; Myers, R E

    1974-01-01

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

    2016-01-01

    Full Text Available An 18-month-old boy presented with abdominal pain, vomiting, diarrhea, and poor appetite for 6 days. He had been given a multivitamin preparation once daily, containing 50.000 IU of vitamin D and 10.000 IU of vitamin A for a wide anterior fontanelle for about three months. He presented with hypercalcemia, low levels of parathyroid hormone (PTH, and very high serum 25-hydroxyvitamin D (25-OHD levels. Renal ultrasound showed nephrocalcinosis. He did not have sign or symptom of vitamin A intoxication. Patient was successfully treated with intravenous hydration, furosemide, and prednisolone. With treatment, serum calcium returned rapidly to the normal range and serum 25-OHD levels were reduced progressively. In conclusion the diagnosis of vitamin D deficiency rickets without checking 25-OHD levels may cause redundant treatment that leads to vitamin D intoxication (VDI.

  20. Foodborne botulinum type E intoxication associated with dried bean curd: first case report in Taiwan.

    Lai, Lung-Shiang; Wang, Yi-Mei; Lin, Chin-Hsien

    2011-06-01

    Botulism type E intoxication is a rare condition among human botulism. We aim to describe a first case of botulism type E intoxication in Taiwan. We report a 36-year-old young man with foodborne botulism type E associated with commercially vacuum packaged dried bean curd. He developed bilateral ptosis, diplopia and dysphagia 4 days after taking the dried bean curd. Electrophysiologic findings demonstrated waxing responses to 3 Hz repetitive nerve stimulation and decreased compound muscle action potentials on peripheral nerve conduction study. A bioassay for botulism in mice demonstrated that the patient had botulism caused by type E botulinum toxin. Antibodeis to C. botulinum type E were identified from his serum, confirming the diagnosis. This is the first known case of foodborne type E botulism in Taiwan. The potential source of this foodborne botulism should consider contaminated food made of soy beans.

  1. A study on the porphirin metabolism in rats in conditions of acute uranium intoxication

    Khadzhirusev, S.; Pavlova, V.; Mikhajlov, M.A.

    1975-01-01

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

    2017-11-01

    Many homemade tamper processes of medical codeine formulations are available on selected "forums" on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called "cold water extraction." Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above-mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event. © 2017 American Academy of Forensic Sciences.

    Full Text Available To investigate the effects of fusel alcohols on the intoxicating degree of liquor products, formulated liquors (FLs were prepared by blending 1-propanol, isobutanol, and isoamyl alcohol with ethanol, organic acids, and corresponding ethyl esters to simulate the formula of traditional Chinese liquors. The prepared FLs were submitted for evaluation of their intoxicating degree (ID. The results showed that the fusel alcohols had a biphasic effect on the IDs of the FLs, depending on the comprehensive coordination of the characteristic minor components. The importance of the suitable ratio of alcohols/acids/esters (RAAE on the IDs was also revealed. Under an optimal ratio level, the fusel alcohols exhibited negligible effects on the IDs of the FLs. Moreover, the ratio of isoamyl alcohol to isobutanol (IA/IB showed a strong positive correlation to the IDs of the FLs. This study lays a foundation for the potential application in producing low-ID liquor.

    2001-04-01

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

The resulting infection in man, known as zoonotic filariasis occur worldwide. Human dirofilariasis, the most common zoonotic filariasis, is caused by the filarial worm belonging to the genus Dirofilaria. Dirofilarial worms, which are recognized as pathogenic in man can cause nodular lesions in the lung, subcutaneous tissue, peritoneal cavity or eyes. Oral dirofilariasis is extremely rare and only a few cases have been documented. We report an interesting case of dirofilariasis due to Dirofilaria repens involving buccal mucosa in a patient who presented with a facial swelling. The clinical features, diagnostic issues and treatment aspects are discussed. This paper stresses the importance of considering dirofilariasis as differential diagnosis for subcutaneous swelling of the face, especially in areas where it is endemic.

  13. Oral sex, oral health and orogenital infections

    Rajiv Saini

    2010-01-01

    Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

  14. PROTEOSE INTOXICATIONS AND INJURY OF BODY PROTEIN : V. THE INCREASE IN NON-PROTEIN NITROGEN OF THE BLOOD IN ACUTE INFLAMMATORY PROCESSES AND ACUTE INTOXICATIONS.

    Cooke, J V; Whipple, G H

    1918-08-01

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

    2017-01-01

    Young adults with higher trait urgency (i.e., a tendency to act rashly in response to heightened affect) may be especially vulnerable to heavy drinking. The current study examined 1) the influence of urgency on daily relations between affect and drinking to intoxication, and 2) whether urgency influenced the effectiveness of naltrexone (vs. placebo) for reducing alcohol use. This study is a secondary analysis of data from 126 (n=40 female) heavy drinking young adults, ages 18-25, enrolled in a double-blind, 8-week clinical trial comparing brief motivational intervention and either naltrexone or placebo. Multilevel models examined whether trait urgency moderated daily relations between positive and negative affect and drinking to intoxication, measured by an estimated blood-alcohol concentration (eBAC) at or above the legal limit (≥0.08g%). Person-level interactions examined whether naltrexone was more effective than placebo at reducing the odds of eBAC≥0.08g% for individuals with higher vs. lower trait urgency. On days of greater within-person positive or negative affect, young adults with higher urgency were more likely to drink to intoxication than those with lower urgency. Naltrexone reduced the odds of drinking to intoxication significantly more than placebo, independent of positive or negative urgency. Although naltrexone treatment reduced drinking overall, young adults with higher trait urgency were still at increased risk for hazardous drinking following times of strong positive or negative mood. Targeted interventions are needed to reduce the risk of heavy drinking among young adults with high trait urgency. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  17. Distinct Roles for CdtA and CdtC during Intoxication by Cytolethal Distending Toxins.

    Shandee D Dixon

    Full Text Available Cytolethal distending toxins (CDTs are heterotrimeric protein exotoxins produced by a diverse array of Gram-negative pathogens. The enzymatic subunit, CdtB, possesses DNase and phosphatidylinositol 3-4-5 trisphosphate phosphatase activities that induce host cell cycle arrest, cellular distension and apoptosis. To exert cyclomodulatory and cytotoxic effects CDTs must be taken up from the host cell surface and transported intracellularly in a manner that ultimately results in localization of CdtB to the nucleus. However, the molecular details and mechanism by which CDTs bind to host cells and exploit existing uptake and transport pathways to gain access to the nucleus are poorly understood. Here, we report that CdtA and CdtC subunits of CDTs derived from Haemophilus ducreyi (Hd-CDT and enteropathogenic E. coli (Ec-CDT are independently sufficient to support intoxication by their respective CdtB subunits. CdtA supported CdtB-mediated killing of T-cells and epithelial cells that was nearly as efficient as that observed with holotoxin. In contrast, the efficiency by which CdtC supported intoxication was dependent on the source of the toxin as well as the target cell type. Further, CdtC was found to alter the subcellular trafficking of Ec-CDT as determined by sensitivity to EGA, an inhibitor of endosomal trafficking, colocalization with markers of early and late endosomes, and the kinetics of DNA damage response. Finally, host cellular cholesterol was found to influence sensitivity to intoxication mediated by Ec-CdtA, revealing a role for cholesterol or cholesterol-rich membrane domains in intoxication mediated by this subunit. In summary, data presented here support a model in which CdtA and CdtC each bind distinct receptors on host cell surfaces that direct alternate intracellular uptake and/or trafficking pathways.

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

    The present paper is devoted to studying, with the aid of different organic dyes, the transmittance spectra of hemoglobin and immunoglobulin G extracted from the blood of laboratory rats, which have been chronically intoxicated with ethanol. The differences in the spectra are detected, when compare with those for the control group. It is shown that the presence of ethanol in blood probably leads to uncoiling partially the hemoglobin molecules. The essential difference is also found in the tra...

  1. Seizures in patients with acute pesticide intoxication, with a focus on glufosinate ammonium.

    Park, S; Kim, D E; Park, S Y; Gil, H W; Hong, S Y

    2018-04-01

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

  2. The effects of alcohol intoxication on attention and memory for visual scenes.

    Harvey, Alistair J; Kneller, Wendy; Campbell, Alison C

    2013-01-01

    This study tests the claim that alcohol intoxication narrows the focus of visual attention on to the more salient features of a visual scene. A group of alcohol intoxicated and sober participants had their eye movements recorded as they encoded a photographic image featuring a central event of either high or low salience. All participants then recalled the details of the image the following day when sober. We sought to determine whether the alcohol group would pay less attention to the peripheral features of the encoded scene than their sober counterparts, whether this effect of attentional narrowing was stronger for the high-salience event than for the low-salience event, and whether it would lead to a corresponding deficit in peripheral recall. Alcohol was found to narrow the focus of foveal attention to the central features of both images but did not facilitate recall from this region. It also reduced the overall amount of information accurately recalled from each scene. These findings demonstrate that the concept of alcohol myopia originally posited to explain the social consequences of intoxication (Steele & Josephs, 1990) may be extended to explain the relative neglect of peripheral information during the processing of visual scenes.

    Wang, Ruiping; Teng, Chengang; Zhang, Ning; Zhang, Jun; Conway, George

    2013-12-01

    In April, 2013, a Suzhou Hospital reported a nitrite intoxication patient in coma as well as 2 family members with the similar symptom 5 days ahead. We investigated the event to identify the cause, source and possible pollution ways of the contamination. We defined case as any person living in YSHY community who has cyanosis and with at least one of the following symptoms: dizziness, headache, fatigue, tachycardia, drowsiness, nausea, vomiting, abdominal pain or diar-rhea during April 15 to April 25, 2013. We searched for case by interviewing community residents and reviewing clinics' medical records; information was then retrospectively collected on the patient's food history, cooking procedures and food sources. We identified 3 nitrite intoxication cases, 1 male and 2 female from a family. The interval time between dinner and onset was mix asparagus' on April 17 and 'scrambled asparagus' on April 21 were suspected foods. Both suspected dishes had 'sugar' added, sourced from a clean-up of a neighboring rental house. Nitrite was detected in a vomitus sample, the 'sugar' and two leftover food samples. This family clustered nitrite intoxication was induced by using unidentified nitrite as sugar to cook dishes. We recommend sodium nitrite should be dyed with bright colors to avoid mistaking it for plain salt or sugar, health departments strengthen food hygiene propaganda to improve people's recognition of food safety, and to alert them the dangerous of eating unidentified or unknown source food.

  4. Defining the Construct of Synthetic Androgen Intoxication: An Application of General Brain Arousal

    Tom Hildebrandt

    2018-03-01

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

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

    Full Text Available Michael D Becker, Brian C YoungEmergency and Critical Care, Animal Specialty Group, Los Angeles, CA, USAAbstract: The objective of this retrospective study was to describe the responses to treatment with intravenous lipid emulsion (ILE and the outcomes for a variety of severe intoxications. This case series includes 10 client-owned animals, 9 dogs and 1 cat, that underwent treatment with ILE for a variety of severe intoxications over a 4-year period. History, physical examination findings, clinical signs, clinicopathological test results, treatment, response to treatment, and outcome were recorded. Eight of the 10 patients survived to discharge. The toxicities included in this case series were baclofen, ivermectin and spinosad plus milbemycin oxime, baclofen and tadalafil, carbamate, methamphetamine, dextroamphetamine sulfate, amlodipine, bromethalin, and organophosphate. The two patients who died were intoxicated with bromethalin and an organophosphate. Six of the 10 patients developed lipemia secondary to ILE administration, and there were no other known adverse effects. Overall, ILE was a safe therapeutic option. This case series provides clinical evidence of successful treatment with ILE as an antidote for previously unpublished toxicities (amlodipine, carbamate, methamphetamine, and dextroamphetamine sulfate, additional evidence of success in treating baclofen and ivermectin toxicosis, as well as unsuccessful treatment of bromethalin and organophosphate toxicities.Keywords: intravenous lipid emulsion, toxicity, amlodipine 

  7. Regulation of porphyrin synthesis and photodynamic therapy in heavy metal intoxication.

    Grinblat, Borislava; Pour, Nir; Malik, Zvi

    2006-01-01

    Protoporphyrin IX (PpIX) synthesis by malignant cells is successfully exploited for photodynamic therapy (PDT) following administration of 5-aminolevulinic acid (ALA) and light irradiation. The influence of two environmental heavy metal poisons, lead and gallium, on PpIX-synthesis and ALA-PDT was studied in two neu-ronal cell lines, SH-SY5Y neuroblastoma and PC12 pheochromocytoma. The heavy metal intoxication affected two of the heme-synthesis enzymes, ALA-dehydratase (ALAD) and porphobilinogen deaminase (PBGD). The present results show that lead poisoning significantly decreased the PBGD cellular level and inhibited its enzymatic activity, whereas the effects of gallium were less prominent. Although, the protein levels were reduced, the mRNA levels of PBGD remained unchanged during metal intoxication. These findings show additional inhibitory activity of lead on top of its classical effect on ALAD. Proteasome activity was enhanced during lead treatment, as measured by the AMC fluorigenic proteasome assay. The reduction in PBGD levels was not a consequence of PBGD mRNA reduced synthesis, which remained unchanged as shown by RT-PCR analysis. As a result of the lead poisoning, marked alterations in the cell cycle were observed, including a decreased G1 phase and an increased number of S phase cells. The efficacy of ALA-PDT was reduced in correlation with decreased activities of the enzymes during lead intoxication. We may conclude that lead poisoning adversely affects the outcome of ALA photodynamic therapy of cancer.

  8. Defining the Construct of Synthetic Androgen Intoxication: An Application of General Brain Arousal.

    Hildebrandt, Tom; Heywood, Ashley; Wesley, Daniel; Schulz, Kurt

    2018-01-01

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

  9. Study II: mechanoreceptive sensation is of increased importance for human postural control under alcohol intoxication.

    Modig, F; Patel, M; Magnusson, M; Fransson, P A

    2012-03-01

    Standing postural stability relies on input from visual, vestibular, proprioceptive and mechanoreceptive sensors. When the information from any of these sensors is unavailable or disrupted, the central nervous system maintains postural stability by relying more on the contribution from the reliable sensors, termed sensory re-weighting. Alcohol intoxication is known to affect the integrity of the vestibular and visual systems. The aim was to assess how mechanoreceptive sensory information contributed to postural stability at 0.00% (i.e. sober), 0.06% and 0.10% blood alcohol concentration (BAC) in 25 healthy subjects (mean age 25.1 years). The subjects were assessed with eyes closed and eyes open under quiet standing and while standing was perturbed by repeated, random-length, vibratory stimulation of the calf muscles. Plantar cutaneous mechanoreceptive sensation was assessed for both receptor types: slowly adapting (tactile sensitivity) and rapidly adapting (vibration perception). The correlation between recorded torque variance and the sensation from both mechanoreceptor types was calculated. The recorded stability during alcohol intoxication was significantly influenced by both the tactile sensation and vibration perception of the subjects. Moreover, the study revealed a fluctuating association between the subjects' vibration perception and torque variance during balance perturbations, which was significantly influenced by the level of alcohol intoxication, vision and adaptation. Hence, one's ability to handle balance perturbations under the influence of alcohol is strongly dependent on accurate mechanoreceptive sensation and efficient sensory re-weighting.

    2017-01-01

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

  11. Somatomedin activity before and after chelation therapy in lead-intoxicated children

    Rohn, R.D.; Hill, J.R.; Shelton, J.E.

    1982-01-01

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

  12. Chronic lead intoxication affects glial and neural systems and induces hypoactivity in adult rat.

    2011-10-01

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

    CONTEXT: Paraquat (PQ) causes lethal intoxication by inducing oxidant injury to the lung. Selenium is a cofactor for glutathione peroxidase (GPx), which is one of the major endogenous antioxidant enzymes. OBJECTIVE: To determine whether selenium post-treatment activates GPx, decreases lung injury, and improves survival in PQ intoxicated rats. MATERIALS AND METHODS: Male Spraque-Dawley rats were categorized into three groups: sham (n = 6), PQ (n = 12), and PQ + Se (n = 12). In the PQ and PQ + Se groups, 50 mg/kg of PQ was administered intraperitoneally. After 10 minutes, 60 μg/kg of Se (PQ + Se) or saline (PQ) was administered via the tail vein. Six rats per group were euthanized 6 hours or 24 hours later. Lung tissues were harvested for the measurement of GPx activity, reduced glutathione (GSH), glutathione disulfide (GSSG) and malondialdehyde (MDA) and for histological analysis. Using separated set of rats, survival of PQ (n = 10) and PQ + Se (n = 10) were observed for 72 hours. RESULTS: GPx activity in the PQ group at the 6-hour and 24-hour time points was lower than in the sham group (p CONCLUSION: Single dose of selenium post-treatment activates GPx and attenuates lipid peroxidation and lung injury early after paraquat intoxication, but does not improve 72 hours of survival.

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

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

  16. On medicative application of complexons in the case of uranium intoxication

    Ivannikov, A.T.

    1987-01-01

    The report deals with the problem of accelerating the uranium elimination from the body in the light of present knowledge. Based on data available in the literature and obtained by the author, effects of sodium bicarbonate, complexons (polyamine-polycarbonic acids) and their phosphonic analogues - polyamine-polyalkyl-phosphonic acids (AMPAs) in the case of uranium intoxication have been analysed. Thus, sodium bicarbonate recommended by the ICRP and IAEA as a remedy for uranium intoxication produces some adverse action reducing its efficiency, while warning against complexons because of risk for kidneys proved to be unjustified. Experimental evidence presented demonstrates conclusively that AMPAs are the most efficient complexing agents for uranium binding and eliminating from the body, essentially superior to complexons due to greater stability constants of AMPA with uranyl ion. AMPAs form stable protonated complexes with uranyl ion which are resistant to acid medium typical of certain kidney parts, so that decomposition of these complexes and deposition of uranium are prevented, thus lowering risk for kidneys. This compares favourably with sodium bicarbonate whose complex with uranyl ion is rather unstable at low pH values. An AMPA compound, Na 6 Ca 2 -diethylene-triamine-pentamethyl- phosphonic acid (the preparation called trimephacin), is adopted in the USSR as an antidote for uranium intoxication and proposed to be included into ICRP Recommendations.

    Glyphosate (N-phosphonomethylglycine) has been used as a broad-spectrum herbicide that has been widely used in the agricultural industry and also available for home use. The main aim of this study is to present a general overview of glyphosate intoxication-related publications from its introducing since the early 1970s using bibliometric technique. On June 23, 2016, a literature search of the Scopus database was performed. We then extracted and analyzed the data using well-established qualitative and quantitative bibliometric indices: Publication year, affiliation, document type, country name, subject category, journal name, publishing language, and collaboration and citation patterns. We recognized a total of 3735 publications on glyphosate published between 1973 and 2015. There were 875 publications related to glyphosate intoxication in the Scopus database published between 1978 and 2015. Articles (757) comprised 86.5% of the total publications, followed by reviews (41; 4.7%). Most publications were published in English (87.9%), followed by Portuguese (6.6%). The number of publications related to glyphosate intoxication increased from 44 in 1978-1987 up to 152 in 1996-2005 and then quadrupled in 2006-2015. The United States was the leading country with 180 documents representing 20.6%, followed by Brazil (120; 13.7%), Canada (78; 8.9%), Argentina (61; 7.0%), and France (57; 6.5%). The 85.6% of the publications was cited, and the average of citation per document was 17.13 with h-index of 55. Furthermore, the United States achieved the highest h-index of 33. Most of the global international collaborations are made with researchers from the United States, who collaborated with 23 countries/territories in 44 publications. The trends in global glyphosate-related research between 1978 and 2015 were evaluated by a bibliometric technique. Results showed that English was the leading publishing language, and the major publication type was original article. Findings showed

  18. A rank based social norms model of how people judge their levels of drunkenness whilst intoxicated

    Simon C. Moore

    2016-09-01

    Full Text Available Abstract Background A rank based social norms model predicts that drinkers’ judgements about their drinking will be based on the rank of their breath alcohol level amongst that of others in the immediate environment, rather than their actual breath alcohol level, with lower relative rank associated with greater feelings of safety. This study tested this hypothesis and examined how people judge their levels of drunkenness and the health consequences of their drinking whilst they are intoxicated in social drinking environments. Methods Breath alcohol testing of 1,862 people (mean age = 26.96 years; 61.86 % male in drinking environments. A subset (N = 400 also answered four questions asking about their perceptions of their drunkenness and the health consequences of their drinking (plus background measures. Results Perceptions of drunkenness and the health consequences of drinking were regressed on: (a breath alcohol level, (b the rank of the breath alcohol level amongst that of others in the same environment, and (c covariates. Only rank of breath alcohol level predicted perceptions: How drunk they felt (b 3.78, 95 % CI 1.69 5.87, how extreme they regarded their drinking that night (b 3.7, 95 % CI 1.3 6.20, how at risk their long-term health was due to their current level of drinking (b 4.1, 95 % CI 0.2 8.0 and how likely they felt they would experience liver cirrhosis (b 4.8. 95 % CI 0.7 8.8. People were more influenced by more sober others than by more drunk others. Conclusion Whilst intoxicated and in drinking environments, people base judgements regarding their drinking on how their level of intoxication ranks relative to that of others of the same gender around them, not on their actual levels of intoxication. Thus, when in the company of others who are intoxicated, drinkers were found to be more likely to underestimate their own level of drinking, drunkenness and associated risks. The implications of these results, for example

  19. Comparison of oral toxicological properties of botulinum neurotoxin serotypes A and B.

    Cheng, Luisa W; Henderson, Thomas D

    2011-07-01

    Botulinum neurotoxins (BoNTs) are among the most potent biological toxins for humans. Of the seven known serotypes (A-G) of BoNT, serotypes A, B and E cause most of the foodborne intoxications in humans. BoNTs in nature are associated with non-toxic accessory proteins known as neurotoxin-associated proteins (NAPs), forming large complexes that have been shown to play important roles in oral toxicity. Using mouse intraperitoneal and oral models of botulism, we determined the dose response to both BoNT/B holotoxin and complex toxins, and compared the toxicities of BoNT/B and BoNT/A complexes. Although serotype A and B complexes have similar NAP composition, BoNT/B formed larger-sized complexes, and was approximately 90 times more lethal in mouse oral intoxications than BoNT/A complexes. When normalized by mean lethal dose, mice orally treated with high doses of BoNT/B complex showed a delayed time-to-death when compared with mice treated with BoNT/A complex. Furthermore, we determined the effect of various food matrices on oral toxicity of BoNT/A and BoNT/B complexes. BoNT/B complexes showed lower oral bioavailability in liquid egg matrices when compared to BoNT/A complexes. In summary, our studies revealed several factors that can either enhance or reduce the toxicity and oral bioavailability of BoNTs. Dissecting the complexities of the different BoNT serotypes and their roles in foodborne botulism will lead to a better understanding of toxin biology and aid future food risk assessments.

  20. Medico-legal and legal-penal aspects of expert opinions and adjudication in cases of intoxications with intoxicating agents and ethanol-like intoxicants

    Monika Ćwiklińska

    2015-08-01

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

  1. MORPHOLOGICAL AND PHYSIOLOGICAL CHANGES ON Schizolobium parahybaVAR .Amazonicum(HUBER EX DUCKE BARNEBY PLANTS INTOXICATED BY GLYPHOSATE

    Kaléo Dias Pereira

    2017-06-01

    Full Text Available The objective of this study was to evaluate the morphological and physiological changes in paricá plants (Schizolobium parahyba var. amazonicum intoxicated by glyphosate. The experiment was conducted in a protected environment using paricá plants during their planting stage, which were intoxicated with increasing doses of glyphosate: 0 (control; 43.2; 86.2; 129.6 and 172.8 g.ha-1. At 7 and 21 days after the application of the herbicide, the photosynthesis, transpiration, stomatal conductance and leaf temperature were measured. The visual intoxication degree and the growth of the shoot and the root of the plants were evaluated 21 days after the application. Paricá shows symptoms of visual intoxication characterized by chlorosis/winding, evolving to necrosis/abscission of the youngest leaflets. The growth of the stem and the roots of the intoxicated plants is preserved; however, an expressive leaf loss occurs, and paricá may have adaptation mechanisms to tolerate the action of the herbicide molecule. The photosynthesis decrease promoted by an indirect action of glyphosate represents the main reduction on the growth of plants. The decrease on the stomatal conductance, which was the most sensitive physiological variable to glyphosate, resulted in lower transpiration rates, which, consequently, caused increases on the leaf temperature.

  2. Morphology of embryonic liver under the influence of silver and gold citrates on a background of lead intoxication

    Harets V.I.

    2016-05-01

    Full Text Available Morphological state of embryonic liver under the influence of silver and gold citrates on a background of lead intoxication was studied. We found that values of the hepatofetal index in the groups Pb+Ag and Pb+Au had significant differences as compared to the group exposed to lead intoxication, but did not differ significantly from the control group and made up 0,086±0,001 and 0,083±0,001, respectively. Value of the relative area of blood vessels in groups Pb+Ag and Pb+Au was 13.08±0.53% and 16.83±0.53%, respectively, which had no significant difference as compared to control group, but differed from the value of lead intoxication group. Under the influence of silver citrate on a background of lead intoxication the relative area of hematopoietic cells was 52,5±0,95%; this indicates to modification action of silver on haematopoiesis. Thus, injection of silver and gold citrates prevents negative effect of lead on morphometric parameters of embryonic liver, relative area of blood vessels and hematopoietic cells. Experiment results showed protective effect of silver and gold citrates on a background of lead intoxication during hepatogenesis.

Self-induced excessive water ingestion is a rare medical condition, which has not been reported in patients with delusional infestation yet. The patient in this case study was a 60-year-old Chinese woman, who was admitted to our hospital because of a feeling of skin infestation. She suffered from loss of consciousness and generalized tonic–clonic seizure after drinking 12 L of water during bowel cleansing before colonoscopy. Sufficient laboratory and imaging examinations were performed to exclude other possible causes of severe hyponatremia, such as hypothyroidism, diabetes insipidus, and syndrome of inappropriate antidiuretic hormone. Besides, the cystic lesion in the posterior pituitary revealed by cranial magnetic resonance imaging was not accountable for her delusional symptoms as well as excessive drinking behavior. Her delusional symptoms were in complete remission with a combination of risperidone and aripiprazole. However, nearly 3 months after discharge, this patient suffered from depressed mood and was diagnosed with depressive syndrome, and even attempted suicide. This case highlights the possibility of self-induced water intoxication in patients with delusional infestation, inevitably adding to the complexity of the disease, and indicates the necessity of precautions for secondary psychotic or mood problems after symptomatological remission.

    2017-12-01

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

    Ipomoea carnea is a toxic plant that affects goats, with symptoms being characterised by nervous disorders and death. Swainsonine and calystegines are the principal toxic components isolated from I. carnea, which also yields lysergic acid derivatives. The aim of this study was to improve the clinical characterisation of experimental intoxication by I. carnea in guinea pigs through the evaluation of behavioural changes and to perform a thorough histopathological analysis of the affected CNS. Leaves of I. carnea were administered to guinea pigs. Open-field gait analysis and monoamine levels were measured. The poisoned animals exhibited increased vocalisation, lethargy, and a reduction in the locomotion frequency after the fourth week of intoxication, as demonstrated in the open-field test. Significant differences were observed in hind-limb gait width by the last week of intoxication. After 65 days, the guinea pigs were euthanised, necropsied, and examined using light and electron microscopy. At the end of the experiment, plasma serotonin decreased. In contrast, dopamine decreased, and noradrenaline increased in urine. Brain sections were evaluated with conventional histological methods and immunohistochemistry (IHC), as well as by transmission electron microscopy (TEM). Vacuoles were observed throughout the brain, but they were particularly prominent in the brainstem. In addition, there were PAS-negative regions, and the Nissl substance was dispersed or absent, which was confirmed with the Kluver-Barreda stain. Moderate microgliosis was observed by immunohistochemistry. In the medulla oblongata, numerous ubiquitin-positive spheroids together with neuronal degeneration were observed in the nucleus gracilis/cuneatus. Furthermore, vacuoles were observed in astrocytes, oligodendrocytes, and endothelial cells by TEM. Our results showed that the behavioural effects may have been caused by alterations in the brain in conjunction with changes in monoamine levels. This

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

  7. Gender, intoxication and the developing brain: Problematisations of drinking among young adults in Australian alcohol policy.

    Manton, Elizabeth; Moore, David

    2016-05-01

    In this article, we draw on recent scholarly work in the poststructuralist analysis of policy to consider how policy itself functions as a key site in the constitution of alcohol 'problems', and the political implications of these problematisations. We do this by examining Australian alcohol policy as it relates to young adults (18-24 years old). Our critical analysis focuses on three national alcohol policies (1990, 2001 and 2006) and two Victorian state alcohol policies (2008 and 2013), which together span a 25-year period. We argue that Australian alcohol policies have conspicuously ignored young adult men, despite their ongoing over-representation in the statistical 'evidence base' on alcohol-related harm, while increasingly problematising alcohol consumption amongst other population subgroups. We also identify the development of a new problem representation in Australian alcohol policy, that of 'intoxication' as the leading cause of alcohol-related harm and rising hospital admissions, and argue that changes in the classification and diagnosis of intoxication may have contributed to its prioritisation and problematisation in alcohol policy at the expense of other forms of harm. Finally, we draw attention to how preliminary and inconclusive research on the purported association between binge drinking and brain development in those under 25 years old has been mobilised prematurely to support calls to increase the legal purchasing age from 18 to 21 years. Our critical analysis of the treatment of these three issues - gender, intoxication, and brain development - is intended to highlight the ways in which policy functions as a key site in the constitution of alcohol 'problems'.

    Full Text Available Background: Determining the prevalence of alcohol intoxication and the level of intoxication in victims of fatal occupational accidents is necessary to improve work safety. The circumstances of the accident and the time between alcohol consumption and death are important factors. Material and Methods: A retrospective review of 18 935 medico-legal autopsy reports and toxicological reports performed in the Department of Forensic Medicine at the Wroclaw Medical University, Poland, in the years 1991–2014. The study protocol included circumstances, time and cause of death, injuries, quantitative testing for the presence of ethyl alcohol, gender and age. Results: There were 98 farm-related fatalities. There were 41.8% (N = 41 of victims who had been intoxicated – 95.1% (N = 39 of them were males aged 19–70 years old, 4,9% (N = 2 were females aged 37–65 years old. In 8 cases the blood alcohol concentration (BAC was 50–150 mg/dl; in 15 cases it was 150–250 mg/dl and in 18 cases it was > 250 mg/dl. In 21 cases, the BAC was determined using alternative material and 76% (N = 16 victims were in the alcohol elimination phase with 19% (N = 4 victims in the alcohol absorption phase. The most common causes of death were traffic accidents, drowning and deaths resulting from being caught in or hit by moving parts of machinery or equipment. Conclusions: Alcohol consumption is a crucial risk factor in fatal agricultural accidents. In order to establish the time of alcohol consumption, all victims of agricultural accidents should be tested for alcohol concentration in their blood and urine or vitreous. Improving safety at work requires that the sobriety of employees should be monitored before and during work. Med Pr 2017;68(1:23–30

  9. Pathobiological and Behavioral Effects of Lead Intoxication in the Infant Rhesus Monkey

    Allen, J. R.; McWey, P. J.; Suomi, S. J.

    1974-01-01

    When infant rhesus monkeys were exposed to lead via the addition of lead acetate (0.5–9 mg/kg body weight) to their formula or by the consumption of lead particles from lead-based surrogate mothers, they developed symptoms of lead intoxication within 6 weeks. Seizures, muscular tremors, and altered social interaction were the predominant changes. Visual impairment was also apparent in the more severely affected animals. In the animals showing obvious symptoms lead levels varied between 300 to 500 μg/100 ml of blood. Even in those animals having blood lead levels below 100 μg, hyperactivity and insomnia were observed. When the exposure to lead was eliminated, seizures subsided and visual impairment was reduced; however, the abnormal social interaction persisted. These animals also experienced a gradual decline in hematocrit and hemoglobin values during the period of examination. Liver and kidney biopsies obtained from these lead-exposed animals revealed characteristic intranuclear inclusions. When adolescent and adult monkeys were exposed to doses of lead acetate similar to those employed in the infant experiments, lead levels in excess of 200 μg/100 ml of blood were recorded. However, there were no obvious behavioral abnormalities observed. There were, however, numerous lead inclusion bodies in kidney biopsy specimens from these animals. These data suggest that, like man, the infant nonhuman primate is much more susceptible to lead intoxication than is the adult. The clinical and behavioral changes recorded in these infant rhesus monkeys suggest their use as an experimental model to evaluate lead intoxication. ImagesFIGURE 6. PMID:4208658

  10. Role of ascorbic acid supplement in reducing oxidative stress and hepatotoxicity in lead intoxication

    2013-01-01

    Objective: The present study was conducted to measure the oxidative stress and hepatotoxicity in lead intoxicated sprague dawley rats with and without supplementation of ascorbic acid. Study Design: Randomized Control Trial. Place of Study: Physiology Department, Army Medical College, Rawalpindi. (From Oct 2007 to Sep 2008) Material and Methods: One hundred and five male rats (age, 90-120 days; weight 200 - 250 gm) were divided into three groups each having 35 rats. Rats of group 1 and group 2 were given weekly injections of sodium acetate (10 mg /kg body weight) and lead acetate (10 mg /kg body weight) respectively, whereas rats of group 3 were administered lead acetate(10 mg /kg body weight) through weekly injections and ascorbic acid in drinking water (500 mg/l). After 6 weeks, 4 ml of blood was drawn from each rat by cardiac puncture. The blood was allowed to clot and serum was separated for estimation of serum malondialdehyde (MDA) levels on spectrophotometer; and serum alanine aminotransferase (ALT) levels and aspartate aminotransferase (AST) levels on Merck Micorlab 200. Results: Lead intoxication of rats revealed that serum MDA levels were raised to 7.8 +- 0.48 micro mol/l (control, 3.2 +-0.39 micro mol/l), ALT levels to 76.26 +- 5.88 IU/l (control, 44.1 +- 3.26) and AST levels to 258.06 +- 13.30 IU/l (control, 156.2 +- 4.97). Ascorbic acid supplementation significantly lowered serum MDA levels (3.8 +- 0.34 micro mol/l), ALT levels (52.26 +-4.57 IU/l) and AST levels (188.13 +- 12.91 IU/l). Conclusion: Ascorbic acid supplementation ameliorates lead intoxication probably by reducing the oxidative stress, thus preventing the development of hepatotoxicity, but this amelioration is not equal to the control.

    2010-01-01

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

  13. Nerve agent intoxication: Recent neuropathophysiological findings and subsequent impact on medical management prospects

    Collombet, Jean-Marc

    2011-01-01

    This manuscript provides a survey of research findings catered to the development of effective countermeasures against nerve agent poisoning over the past decade. New neuropathophysiological distinctive features as regards organophosphate (OP) intoxication are presented. Such leading neuropathophysiological features include recent data on nerve agent-induced neuropathology, related peripheral or central nervous system inflammation and subsequent angiogenesis process. Hence, leading countermeasures against OP exposure are down-listed in terms of pre-treatment, protection or decontamination and emergency treatments. The final chapter focuses on the description of the self-repair attempt encountered in lesioned rodent brains, up to 3 months after soman poisoning. Indeed, an increased proliferation of neuronal progenitors was recently observed in injured brains of mice subjected to soman exposure. Subsequently, the latter experienced a neuronal regeneration in damaged brain regions such as the hippocampus and amygdala. The positive effect of a cytokine treatment on the neuronal regeneration and subsequent cognitive behavioral recovery are also discussed in this review. For the first time, brain cell therapy and neuronal regeneration are considered as a valuable contribution towards delayed treatment against OP intoxication. To date, efficient delayed treatment was lacking in the therapeutic resources administered to patients contaminated by nerve agents. - Highlights: → This review focuses on neuropathophysiology following nerve agent poisoning in mice. → Extensive data on long-term neuropathology and related inflammation are provided here. → Delayed self-repair attempts encountered in lesioned rodent brains are also described. → Cell therapy is considered as a valuable treatment against nerve agent intoxication.

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

    Although glufosinate ammonium herbicides are considered safe when used properly, ingestion of the undiluted form can cause grave outcomes. Recently, we treated a 34-yr-old man who ingested glufosinate ammonium herbicide. In the course of treatment, the patient developed apnea, mental deterioration, and sixth cranial nerve palsy; he has since been discharged with full recovery after intensive care. This case report describes the clinical features of glufosinate intoxication with a focus on sixth cranial nerve palsy. Our observation suggests that neurologic manifestations after ingestion of a "low-grade toxicity herbicide" are variable and more complex than that was previously considered.

  17. [Evaluation of selected socioeconomic factors in patients with acute ethanol intoxication and alcohol withdrawal syndrome].

    Lukasik-Głębocka, Magdalena; Sommerfeld, Karina

    2014-01-01

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

  19. Results of using low-intensity laser radiation for plumbum intoxication

    Dejneka, S. Y.

    1999-11-01

    We have studied the noninvasive effect of low-intensive laser impulse radiation in the infrared spectrum region on the liver projection site in experimental lead intoxication achieved by means of intragastric administration of Pb acetate to albino rats over a period of 30 days in a dose of 30 mg/kg. We determined a number of indices in laboratory animals which characterized the state of the nervous system, immune system, muscular performance efficiency. We have also investigated the hematologic indices and the blood and urinary delta-aminolevulinic acid content as well as the plumbum levels in the blood, urine and the animals' inner organs.

    We present a case of voluntary intake of methyl alcohol studied by means of computerized tomography (CT) in a previously healthy patient. The classical findings of bilateral putaminal necrosis are corroborated and cerebral white matter lesions are detected in frontal and occipital zones, signs that are unusual in this disorder. CT can be of diagnostic interest in certain comas of metabolic origin such as methanol intoxication, revealing antemortem lesions of both putamens and white matter. Finally, a correlation between the CT and necropsy findings is established. (Author) 11 refs

    Inhalant withdrawal symptoms have previously been described but not well documented. This case-series describes the sociodemographic and clinical characteristics of nine children and adolescents with gasoline abuse. Gasoline inhalation was the drug of choice in our patients. The mean age was 13.6 years and all the subjects belonged to low socioeconomic status. Most of the subjects used daily and all subjects reported alcohol abuse in the father. All subjects reported a syndrome of intoxication as described in previous reports. All subjects also reported a withdrawal syndrome including irritability, psychomotor retardation, anhedonia, dry mouth, sleep disturbances, craving, and increased lacrimation.

  2. Ergot alkaloid intoxication in perennial ryegrass (Lolium perenne): an emerging animal health concern in Ireland?

    Canty, Mary J; Fogarty, Ursula; Sheridan, Michael K; Ensley, Steve M; Schrunk, Dwayne E; More, Simon J

    2014-01-01

    Four primary mycotoxicosis have been reported in livestock caused by fungal infections of grasses or cereals by members of the Clavicipitaceae family. Ergotism (generally associated with grasses, rye, triticale and other grains) and fescue toxicosis (associated with tall fescue grass, Festuca arundinacea) are both caused by ergot alkaloids, and referred to as 'ergot alkaloid intoxication'. Ryegrass staggers (associated with perennial ryegrass Lolium perenne) is due to intoxication with an indole-diperpene, Lolitrem B, and metabolites. Fescue-associated oedema, recently described in Australia, may be associated with a pyrrolizidine alkaloid, N-acetyl norloline. Ergotism, caused by the fungus Claviceps purpurea, is visible and infects the outside of the plant seed. Fescue toxicosis and ryegrass staggers are caused by Neotyphodium coenophalium and N. lolii, respectively. Fescue-associated oedema has been associated with tall fescue varieties infected with a specific strain of N. coenophialum (AR542, Max P or Max Q). The name Neotyphodium refers to asexual derivatives of Epichloë spp., which have collectively been termed the epichloë fungi. These fungi exist symbiotically within the grass and are invisible to the naked eye. The primary toxicological effect of ergot alkaloid involves vasoconstriction and/or hypoprolactinaemia. Ingestion of ergot alkaloid by livestock can cause a range of effects, including poor weight gain, reduced fertility, hyperthermia, convulsions, gangrene of the extremities, and death. To date there are no published reports, either internationally or nationally, reporting ergot alkaloid intoxication specifically associated with perennial ryegrass endophytes. However, unpublished reports from the Irish Equine Centre have identified a potential emerging problem of ergot alkaloid intoxication with respect to equines and bovines, on primarily perennial ryegrass-based diets. Ergovaline has been isolated in varying concentrations in the herbage of a

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

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

  5. Ritualistic Use of Ayahuasca versus Street Use of Similar Substances Seized by the Police: A Key Factor Involved in the Potential for Intoxications and Overdose?

    The ritualistic use of ayahuasca is becoming a global phenomenon. This beverage contains a combination of monoamine oxidase inhibitors (harmine, harmaline, and tetrahydroharmine) and N,N-dimethyltryptamine, the main substance responsible for its visionary effect. The recreational use of similar alkaloids and N,N-dimethyltryptamine has increased in recent years, mainly because of their hallucinogenic effects. In the present study, the concentrations of psychoactive alkaloids in three powder samples seized by the São Paulo State Police and nine ayahuasca aqueous extracts were analyzed by HPLC-DAD in an attempt to distinguish between illicit drugs and the religious beverage. The alkaloids detected (μg/mL) in the ayahuasca aqueous extracts were N,N-dimethyltryptamine (402-2070.3), harmaline (27.5-181.3), harmine (294.5-2893.8), and tetrahydroharmine (849.5-2052.5), whereas, of the three powder samples, one contained only N,N-dimethyltryptamine (82% and 2% w/w, respectively) while the other contained only harmaline (16%, w/w) and harmine (12%, w/w). The ritualistic use of ayahuasca involves oral intake and the probability of overdose is minimized by serotonergic stimulation of vagal pathways, leading to vomiting and diarrhea. In contrast, the recreational use of N,N-dimethyltryptamine involves consumption mainly by smoking or inhalation, both of which markedly increase its bioavailability and the potential for intoxications.

    Lead intoxication induces oxidative damage on lipids and proteins. In the present paper we study in vivo and in vitro the antioxidant effect of vitamin-E and trolox, on the oxidative effects of lead intoxication in rat erythrocytes. Vitamin-E simultaneously administered to erythrocytes treated with lead was capable to prevent the inhibition of delta-aminolevulinic dehydratase activity and lipid oxidation. Partial but important protective effects were found when vitamin-E was administered either after or before lead exposure in rats. In vitro, the antioxidant trolox protected delta-ALA-D activity against damage induced by lead or menadione. These results indicate that vitamin-E could be useful in order to protect membrane-lipids and, notably, to prevent protein oxidation produced by lead intoxication.

    1975-01-01

    Incorporation of 14 C glucose into glycogen and glucose-6-phosphate dehydrogenase activity in rat brain following carbon monoxide intoxication was studied. In brains of rats tested on the 20, 30 and 60th minute of exposure to CO and immediately after removal from the chamber the enzyme activity showed no essential deviation from the control level. In the group of rats tested 1 hour after taking them out from the chamber increase of the enzyme activity was noticed, amounting to about 33% of the control value. The brains tested 24 hours after exposure showed the largest increase of the enzyme activity by about 94%. In the next time periods, 48 and 72 hours after intoxication, the enzyme activity was decreasing. The glycogen content in brains of control animals increased 3 hours after CO intoxication by about 69%. The increase of glycogen synthesis was expressed by increase of the total radioactivity, which amounted to 160% of the control value. (Z.M.)

  8. Hyperbaric oxygen therapy or hydroxycobalamin attenuates surges in brain interstitial lactate and glucose; and hyperbaric oxygen improves respiratory status in cyanide-intoxicated rats

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

    Full Text Available In this study pure Aflatoxin B1 (AFB1 was given to broiler birds at the rate of 50, 100, 200, 400 and 800µg/kg feed for 28 days. Birds of experimental groups intoxicated with 50, 100 and 200µg/kg feed did not show any clinical and behavior alteration. Birds of experimental groups intoxicated with 400 and 800µg/kg showed depression, ruffled feathers and had decreased feed intake, increased water consumption with soft to watery feces. Birds fed 800µg/kg AFB1 for 28 days also exhibited nervous signs (torticollis. Mortality occurred in all treatment groups with the exception of those given 50 and 100µg/kg AFB1 for 28 days. Clinical signs and mortality percentages score increased with the increase in AFB1 levels. Dose related significantly decreased in relative organs weight were recorded in all groups with the exception of birds given 50 and 100µg/kg AFB1 for 28 days. Significantly increased scores of gross lesions were recorded with increasing dietary levels of AFB1. The present study concluded that, AFB1 at level of 50µg/kg feed did not show any behavioral, gross and pathological effect on broilers when fed continuously for 28 day. In other groups pathological changes were seen in dose related manner. Severe changes were seen in higher dose levels.

  12. Oleander intoxication in New World camelids: 12 cases (1995-2006).

    Kozikowski, Tania A; Magdesian, K Gary; Puschner, Birgit

    2009-08-01

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

  13. CD44 Promotes intoxication by the clostridial iota-family toxins.

    Wigelsworth, Darran J; Ruthel, Gordon; Schnell, Leonie; Herrlich, Peter; Blonder, Josip; Veenstra, Timothy D; Carman, Robert J; Wilkins, Tracy D; Van Nhieu, Guy Tran; Pauillac, Serge; Gibert, Maryse; Sauvonnet, Nathalie; Stiles, Bradley G; Popoff, Michel R; Barth, Holger

    2012-01-01

    Various pathogenic clostridia produce binary protein toxins associated with enteric diseases of humans and animals. Separate binding/translocation (B) components bind to a protein receptor on the cell surface, assemble with enzymatic (A) component(s), and mediate endocytosis of the toxin complex. Ultimately there is translocation of A component(s) from acidified endosomes into the cytosol, leading to destruction of the actin cytoskeleton. Our results revealed that CD44, a multifunctional surface protein of mammalian cells, facilitates intoxication by the iota family of clostridial binary toxins. Specific antibody against CD44 inhibited cytotoxicity of the prototypical Clostridium perfringens iota toxin. Versus CD44(+) melanoma cells, those lacking CD44 bound less toxin and were dose-dependently resistant to C. perfringens iota, as well as Clostridium difficile and Clostridium spiroforme iota-like, toxins. Purified CD44 specifically interacted in vitro with iota and iota-like, but not related Clostridium botulinum C2, toxins. Furthermore, CD44 knockout mice were resistant to iota toxin lethality. Collective data reveal an important role for CD44 during intoxication by a family of clostridial binary toxins.

  14. Human alpha-defensin-1 protects cells from intoxication with Clostridium perfringens iota toxin.

    Fischer, Stephan; Popoff, Michel R; Barth, Holger

    2018-03-01

    Iota toxin is produced by Clostridium perfringens type E strains and associated with diarrhea in cattle and lambs. This binary protein toxin comprises the enzyme component iota a (Ia), which ADP-ribosylates G-actin, and the separate transport component iota b (Ib), which delivers Ia into the cytosol of target cells. Ib binds to cell receptors and forms biologically active toxin complexes with Ia, which cause rounding of adherent cells due to the destruction of the actin cytoskeleton. Here, we report that the human peptide α-defensin-1 protects cultured cells including human colon cells from intoxication with iota toxin. In contrast, the related ß-defensin-1 had no effect, indicating a specific mode of action. The α-defensin-1 did not inhibit ADP-ribosylation of actin by Ia in vitro. Pretreatment of Ib with α-defensin-1 prior to addition of Ia prevented intoxication. Additionally, α-defensin-1 protected cells from cytotoxic effects mediated by Ib in the absence of Ia, implicating that α-defensin-1 interacts with Ib to prevent the formation of biologically active iota toxin on cells. In conclusion, the findings contribute to a better understanding of the functions of α-defensin-1 and suggest that this human peptide might be an attractive starting point to develop novel pharmacological options to treat/prevent diseases associated with iota toxin-producing Clostridium perfringens strains.

    Full Text Available Objective: To assess the hepatoprotective effect of ethanol extracts of Sargassum variegatum (S. variegatum, Sargassum tenerrimum (S. tenerrimum and Sargassum binderi occurring at Karachi coast against carbon tetrachloride (CCl4 and acetaminophen intoxication in rats. Methods: Sargassum species were collected at low tide from Buleji beach at Karachi coast. Effect of ethanol extracts of Sargassum spp., on lipid parameter, serum glucose and kidney function was examined. Liver damage in rats was induced by CCl4 or acetaminophen. Rats were administered with ethanol extracts of S. tenerrimum, S. variegatum and Sargassum binderi at 200 mg/kg body weight daily for 14 days separately. Hepatotoxicity was determined in terms of cardiac and liver enzymes and other biochemical parameters. Results: S. variegatum showed highest activity by reducing the elevated level of hepatic enzymes, bilirubin, serum glucose, triglyceride with restoration of cholesterol. Urea and creatinine concentrations were also significantly (P < 0.05 reduced as compared to acetaminophen intoxicated rats. S. tenerrimum and S. variegatum showed moderate activity against CCl4 hepatic toxicity. Conclusions: The protective role of S. variegatum against acetaminophen liver damage and its positive impact on disturbed lipid, glucose metabolism, kidney dysfunction and S. tenerrimum against CCl4 liver toxicity suggest that Sargassum species offer a non-chemical means for the treatment of toxicity mediated liver damage.

    Ten Broeke, R; Mestrom, E; Woo, L; Kreeftenberg, H

    2016-06-01

    This case report describes the possible benefit of intravenous lipid emulsion in two patients surviving a severe intoxication with hydroxychloroquine in a dose that was previously considered to be lethal. The first case involves a 25-year-old female who ingested 17.5 grams of hydroxychloroquine, approximately one hour before presentation. An ECG showed QRS widening and the lab results showed hypokalaemia. She became unconscious, and developed hypotension and eventually apnoea. After intubation, supportive care consisted of norepinephrine and supplementation of potassium. Moreover, sodium bicarbonate and intravenous lipid emulsion were started to prevent cardiac toxicity. After these interventions, haemodynamic stability was established within a few hours. Although cardiomyopathy was confirmed, the patient recovered after two weeks. The second case concerns a 25-year-old male who took 5 grams of hydroxychloroquine. At presentation, two hours after intake, he showed QTc prolongation and hypokalaemia. The patient was treated with the usual supportive care and, although presentation to hospital was later, with intravenous lipid emulsion. Also this patient recovered. In conclusion, these cases show the benefit of supplemental intravenous lipid emulsion to prevent cardiac toxicity after a severe intoxication with hydroxychloroquine.

    Noda, Anna Hiro; Schu, Ulrich; Maier, Tanja; Knake, Susanne; Rosenow, Felix

    2017-03-01

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

  19. Witnesses' memory for events and faces under elevated levels of intoxication.

    2018-08-01

    Research on alcohol and witness memory has burgeoned over the last decade. However, most studies have tested participants at relatively low breath alcohol concentration (BAC) levels, unrepresentative of those encountered by officers in the field. To examine how higher intoxication levels might impair witness memory for events and faces, the current research tested participants' ability to recall a mock crime at elevated BAC levels (>.08%). The BAC levels of bar patrons (N = 138) were recorded before witnessing a video-taped mock crime. Participants were then interviewed using free recall and cued questions and shown a six-person target-present or target-absent lineup. Results show that alcohol negatively affected both the quantity and quality of recall. Regardless of question format, alcohol also reduced the percentage of accurate information elicited from witnesses; however, only cued questions increased the percentage of inaccurate information reported. Intoxication had no effect on identification accuracy. These findings suggest that the encoding and storage systems for faces and events may be impacted differently by alcohol. Our results also highlight the importance of including higher BAC levels when examining the effects of alcohol on witness memory.

    2017-01-01

    The current study was conducted to investigate the protective effect of spermine, a natural polyamine against toxicity of lead and /or gamma irradiation in male rats. Eight groups of rats were used in this study (control, irradiated group (6 GY), lead (40 mg/kg bw), spermine (10 mg/kg bw), lead plus irradiation, irradiation plus spermine, lead plus spermine, irradiation plus lead co-treated with spermine) for consecutive 14 days. Blood samples were used for complete blood count (CBC) and glucose 6-phosphate-dehydrogenase (G6PD) levels. Moreover, malondialdhyde (MDA), glutathione (GSH), metallothionein (MT) levels and catalase (CAT) activity were investigated in liver, kidney and brain. G6PD activity significantly decreased post exposure to lead and /or gamma irradiation. Hepatic, renal and brain MDA, GSH, MT and CAT were significantly increased in lead intoxicated group, while GSH, MT and CAT activity were significantly decreased in gamma-irradiated group. Spermine administration alleviated changes in CBC, G6PD, MDA, MT and CAT to normal control levels, but with significant increase in G6PD activity and platelets count. In conclusion, spermine acts as an antioxidant and plays a prophylactic role against intoxication with lead and/or gamma irradiation exposure.

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

    June H. Williams

    2016-11-01

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

    2012-08-01

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

    2018-02-01

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

    Full Text Available Till date, drugs that have been used to manage Parkinson’s disease (PD have only shown symptomatic relief with several adverse effects besides their inability to prevent neurodegeneration. Neuroinflammation plays an important role in the advancement of PD and can be targeted for its effective treatment. Researchers have suggested that herbal plants exhibiting the anti-inflammatory and anti-oxidant properties are therefore beneficial to human health. Conventionally, Mucuna pruriens (Mp seeds are used for maintaining male virility in India. Reportedly, Mp is used as a rejuvenator drug having neuroprotective property. Our study aimed to investigate effects of aqueous extract of Mp (100 mg/kgbwt on neuroinflammation, orally administered to mice intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP as well as the molecular mechanism involved in the progression of PD. In this study, we have observed significant behavioral abnormalities beside decreased antioxidant defense in MPTP intoxicated mice. We have also observed significant increase in inflammatory parameters like Glial Fibrillary Acidic Protein, Inducible Nitric Oxide Synthase, Intercellular Cell Adhesion Molecule, and Tumor Necrosis Factor alpha in substantia nigra pars compacta (SNpc of parkinsonian mice, while Mp treatment has notably reduced these inflammatory parameters. Mp also inhibited the MPTP induced activation of NF-κB and promoted pAkt1 activity which further prevented the apoptosis of the dopaminergic neurons. Moreover, Mp exhibited significant antioxidant defense by inhibiting the lipid peroxidation and nitrite level, and by improving catalase activity and enhancing GSH level in nigrostriatal region of mouse brain. Mp also recovered the behavioral abnormalities in MPTP treated mice. Additionally, Mp treatment considerably increased the immunoreactivity of Tyrosine Hydroxylase and Dopamine Transporter in SNpc of parkinsonian mice. Our high performance liquid

    The limited number of oral vaccines currently approved for use in humans and veterinary species clearly illustrates that development of efficacious and safe oral vaccines has been a challenge not only for fish immunologists. The insufficient efficacy of oral vaccines is partly due to antigen breakdown in the harsh gastric environment, but also to the high tolerogenic gut environment and to inadequate vaccine design. In this review we discuss current approaches used to develop oral vaccines fo...

  9. Perception of intoxication in a field study of the night-time economy: Blood alcohol concentration, patron characteristics, and event-level predictors.

    Kaestle, Christine E; Droste, Nicolas; Peacock, Amy; Bruno, Raimondo; Miller, Peter

    2018-01-01

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

  12. Essentials of oral cancer.

    Rivera, César

    2015-01-01

    Oral cancer is one of the 10 most common cancers in the world, with a delayed clinical detection, poor prognosis, without specific biomarkers for the disease and expensive therapeutic alternatives. This review aims to present the fundamental aspects of this cancer, focused on squamous cell carcinoma of the oral cavity (OSCC), moving from its definition and epidemiological aspects, addressing the oral carcinogenesis, oral potentially malignant disorders, epithelial precursor lesions and experimental methods for its study, therapies and future challenges. Oral cancer is a preventable disease, risk factors and natural history is already being known, where biomedical sciences and dentistry in particular are likely to improve their poor clinical indicators.

  13. Musculus gastrocnemius tetanus kinetics in alcohol-intoxicated rats with experimentally-induced hindlimb vascular ischemia under conditions of low-frequence muscle fatigue

    O. A. Melnychuk

    2014-04-01

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

    Full Text Available ABSTRACT The aim of the study was to evaluate the effectiveness of preventive-detox preparation (P-dP based on humic and aluminosilicate substances in the diet of laying hens (3% daily dose previously intoxicated with methylmercury chloride (CH3ClHg, 5 mg Hg/kg feed mixture for six weeks. Mercury content in the whole eggs of the group intoxicated with CH3ClHg increased compared to the control group: 488-fold after 1 wk, 622-fold after 2 wks, and 853-fold after 6 wks of intoxication. The use of P-dP in the group previously intoxicated with CH3ClHg reduced he mercury content of whole eggs by 18.4%, on average, whereas the average was 29.9% two weeks after the discontinuation of CH3ClHg and P-dP supply. Maximum Hg content in the whole egg was observed in group III (299.7 g, whereas the highest mercury level was obtained in the egg albumen.

    2008-01-01

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

    Objective: To investigate the possible ameliorative effect of crude water extract of Morus alba(M. alba) leaves on retinopathy of rat pups maternally subjected to diabetes and/or Al intoxication.Methods: Both control and experimental groups were subjected to certain integrated approaches, namely, biochemical assessments, light microscopic investigation, transmission electron microscopic investigation, single cell gel electrophoresis(comet assay) and determination of DNA fragmentation.Results: The retina of pups of diabetic and/or Al-intoxicated mothers exhibited abnormal alterations in retinal cell layers including retinal pigmented epithelium, photoreceptor inner segment and ganglion cells. Increased incidence of DNA fragmentation and apoptosis were evident in pups of diabetic and/or Al-intoxicated mothers. However, retina of pups maternally received M. alba extract plus diabetes or Al-intoxicated alone or in combination showed marked amelioration. Less degree of ameliorations was seen in retina of pups maternally subjected to combined treatment. Furthermore, application of crude water extract of M.alba resulted in amelioration of the alterations of maternal serum glucose as well as Al concentration.Conclusions: Based on the results of the present study, M. alba extract is effective against experimentally diabetic and Al-induced developmental retinopathy.

  20. Increase in the penetration of tracer compounds into the rat brain during 2-methyl-4-chlorophenoxyacetic acid (MCPA) intoxication

    The penetration of different intravenous tracer molecules such as 14 C-labelled 2-methyl-4-chlorophenoxyacetic acid ( 14 C-MCPA), 14 C-p-aminobenzoic acid ( 14 C-PABA), 14 C-sucrose, 14 C-antipyrine and iodinated ( 125 I) human albumin ( 125 I-HA) into the brain and cerebrospinal fluid (CSF) was studied in MCPA-intoxicated and control rats. Toxic subcutaneous doses of sodium salt of MCPA (200-500 mg/kg) increased highly the brain/plasma and CSF/plasma ratios of 14 C-MCPA and 14 C-PABA, as compared to the muscle/plasma ratio. Probenecid (200 mg/kg) did not affect the cerebral MCPA concentration in the intoxicated animals. The tissue/plasma ratios of 14 C-sucrose, 14 C-antipyrine and 125 I-HA were also increased in the brain and CSF of intoxicated animals, but the increases were less pronounced than those of 14 C-MCPA or 14 C-PABA. The results indicate that MCPA intoxication caused a selective damage of the blood-brain barrier in the brain areas studied. (author)

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

  4. Alcohol Hits You When It Is Hard: Intoxication, Task Difficulty, and Theta Brain Oscillations.

    Alcohol intoxication is known to impair decision making in a variety of situations. Previous neuroimaging evidence suggests that the neurofunctional system subserving controlled processing is especially vulnerable to alcohol in conflict-evoking tasks. The present study investigated the effects of moderate alcohol intoxication on the spatiotemporal neural dynamics of event-related total theta (4 to 7 Hz) power as a function of task difficulty. Two variants of the Simon task manipulated incongruity via simple spatial stimulus-response mismatch and, in a more difficult version, by combining spatial and semantic interference. Healthy social drinkers participated in both alcohol (0.6 g/kg ethanol for men, 0.55 g/kg for women) and placebo conditions in a counterbalanced design. Whole-head magnetoencephalography (MEG) signals were acquired and event-related total theta power was calculated on each trial with Morlet wavelets. MEG sources were estimated using anatomically constrained, noise-normalized, spectral dynamic statistical parametric mapping. Longer reaction times and lower accuracy confirmed the difficulty manipulation. Response conflict (incongruity) increased and alcohol intoxication decreased event-related theta power overall during both tasks bilaterally in the medial and ventrolateral prefrontal cortices. However, alcohol-induced theta suppression was selective for conflict only in the more difficult task which engaged the dorsal anterior cingulate (dAC) and anterior inferolateral prefrontal cortices. Theta power correlated negatively with drinking levels and disinhibition, suggesting that cognitive control is susceptible in more impulsive individuals with higher alcohol intake. The spatiotemporal theta profile across the 2 tasks supports the concept of a rostrocaudal activity gradient in the medial prefrontal cortex that is modulated by task difficulty, with the dAC as the key node in the network subserving cognitive control. Conflict-related theta power was

    Oral cancer is considered as a serious health problem resulting in high morbidity and mortality. Early detection and prevention play a key role in controlling the burden of oral cancer worldwide. The five-year survival rate of oral cancer still remains low and delayed diagnosis is considered as one of the major reasons. This increases the demand for oral screening. Currently, screening of oral cancer is largely based on visual examination. Various evidence strongly suggest the validity of visual inspection in reducing mortality in patients at risk for oral cancer. Simple visual examination is accompanied with adjunctive techniques for subjective interpretation of dysplastic changes. These include toluidine blue staining, brush biopsy, chemiluminescence and tissue autofluorescence. This review highlights the efficacy of various diagnostic methods in screening of oral cancer. © 2016 Old City Publishing, Inc.

  6. Oral biopsy: Oral pathologist′s perspective

    K L Kumaraswamy

    2012-01-01

    Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

  7. Alcohol intoxication at Swedish football matches: A study using biological sampling to assess blood alcohol concentration levels among spectators.

    Natalie Durbeej

    Full Text Available Alcohol use and alcohol-related problems, including accidents, vandalism and violence, at sporting events are of increased concern in Sweden and other countries. The relationship between alcohol use and violence has been established and can be explained by the level of intoxication. Given the occurrence of alcohol use and alcohol-related problems at sporting events, research has assessed intoxication levels measured through biological sampling among spectators. This cross-sectional study aimed to assess the level of alcohol intoxication among spectators at football matches in the Swedish Premier Football League. Spectators were randomly selected and invited to participate in the study. Alcohol intoxication was measured with a breath analyser for Blood Alcohol Concentration levels, and data on gender, age, and recent alcohol use were gathered through a face-to-face interview. Blood Alcohol Concentration samples from 4420 spectators were collected. Almost half (46.8% had a positive Blood Alcohol Concentration level, with a mean value of 0.063%, while 8.9% had a Blood Alcohol Concentration level ≥ 0.1%, with a mean value of 0.135%. Factors that predicted a higher Blood Alcohol Concentration level included male gender (p = 0.005, lower age (p < 0.001, attending a local derby (p < 0.001, alcohol use prior to having entered the arena (p < 0.001, attending a weekend match (p < 0.001, and being a spectator at supporter sections (p < 0.001. About half of all spectators at football matches in the Swedish Premier Football League drink alcohol in conjunction with the match. Approximately one tenth have a high level of alcohol intoxication.

    Caffeinated alcoholic beverages have been associated with increased risk of alcohol-related harms. However, few studies have examined these combined effects on behavioural control, which is believed to underlie many of the negative effects of alcohol consumption. In addition, studies have often omitted subjective measures, and none have directly assessed the role of caffeine consumer history. To examine the combined effects of alcohol and caffeine on measures of behavioural control and perceived intoxication in abstinent, light caffeine consumers. Participants (n = 28; 50% male) attended four sessions at which they consumed one of the following beverages in a randomised order: placebo, alcohol alone (0.6 g/kg), caffeine alone (2.0 mg/kg), and alcohol/caffeine. They completed measures of mood, intoxication, anxiety and alcohol craving before and after a task battery comprising measures of behavioural control and reaction time performance. Caffeine attenuated alcohol-related performance deficits on stop-signal accuracy, had no effect on go-no-go performance deficits, and worsened accuracy on the Stroop task. Caffeine did not influence absolute changes in perceived intoxication but there was suggestion that caffeine may have changed the nature of intoxication with increases in stimulation. Caffeine appears to have mixed effects on alcohol intoxication that are task-dependent. We found increased stimulation in the alcohol/caffeine condition, supporting the contention that caffeinated alcoholic beverages enable an individual to drink for longer. Future research should model real world drinking behaviour by examining how these effects change across multiple drink administrations.

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

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

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

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

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

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

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

    Bui, Quan M.

    2015-05-01

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

    1988-01-01

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

    2007-01-01

    The present investigation was undertaken to evaluate and determine the protective effect of intraperitoneal administration of trace mineral selenium (Se) and antioxidant vitamins E and pantothenic acid (PA) to male albino rats intoxicated with methomyl pesticide. Four groups of rats were used in this study. The data obtained revealed that methomyl caused disturbances in liver functions, which were elucidated through ALT and AST levels, and in the levels of serum glucose and insulin. Also, the levels of serum total protein, albumin, total lipids, triglycerides, cholesterol and acethylcholinesterase activity were significantly changed from those found in control rats for different periods. Treatment of rats with the antioxidant supplements ameliorated to some extent most of the disturbances in the mentioned biochemical parameter levels. The data concluded that such antioxidants could provide some protection against pesticide-induced toxicity

    1975-11-01

    The removal of salicylate by extracorporeal circulation of blood through a column of encapsulated charcoal (haemoperfusion) has been studied experimentally in intoxicated dogs (greyhounds). The average time taken to reduce the whole blood salicylate level to one-half of the initial equilibrium level in 30 kg dogs was 2 hrs. A half-life of 3 hrs is predicted for salicylate removal by haemoperfusion in a 70 kg man and this rate of removal is shown to be comparable to that reported for haemodialysis. No unacceptable adverse physiological, biochemical, or haematological effects were found to result from haemoperfusion. The possible use of this technique in the management of severe salicylate poisoning in man is discussed. Haemoperfusion is foreseen as providing a method of rapid removal of salicylate in circumstances where forced diuresis is contra-indicated or inadequate and haemodialysis is not readily available.

  19. Intoxication by star fruit (Averrhoa carambola) in six dialysis patients? (Preliminary report)

    Neto, M M; Robl, F; Netto, J C

    1998-03-01

    We observed six cases of patients in a dialysis programme who were apparently intoxicated by ingestion of star fruit. After ingestion of 2-3 fruits or 150-200 ml of the fruit juice, the six patients, who had previously been stable in a regular dialysis programme, developed a variety of symptoms ranging from insomnia and hiccups to agitation, mental confusion and (in one case) death. In preliminary investigations to characterize the hypothetical neurotoxin in the fruit, an extract, when injected intraperitoneally or intracerebroventricularly in rats, provoked persistent convulsions of the tonic-clonic type. It appears that star fruit (Averrhoa carambola) contains an excitatory neurotoxin. Patients with renal failure on conservative or dialysis treatment should be dissuaded from ingestion of the fruit.

    Chronic alcohol abuse has adverse effects on skeletal muscle, and reduced muscle strength is frequently seen in chronic alcoholics. In this study the acute effects of moderate alcohol intoxication on motor performance was evaluated in 19 non-alcoholic healthy subjects (10 women, 9 men......). A randomised double-blinded placebo controlled design was applied to subjects receiving alcohol in juice and pure juice at two separate test periods. Isokinetic and isometric muscle strength and endurance were determined before, during, 24 and 48 h after the ingestion of alcohol in juice and juice (placebo......). To detect a reduced activation of the central motor pathways superimposed external electrical stimulations during voluntary contractions were applied. Creatine kinase (CK) was measured to detect any alcohol-induced changes in sarcolemmal integrity. No change was seen in isokinetic as well as in isometric...

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

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

    Studies have emphasized screening for psychiatric disorders, especially suicide risk in emergency departments. Psychiatric disorders and experimentation with alcohol increase in adolescence and intoxications among patients challenge the staff in emergency departments. This study examined the degree of suicidal ideation (SI) and suicidal behavior in adolescents, and the extent to which they differed from non-suicidal patients in terms of alcohol use, psychological distress, self-esteem, and perceived social support. The study comprised 120 adolescents, a mean age of 14.2 years. Of them 60% were females. We collected data on the clinical characteristics and assessed the patient's psychiatric status using self-report scales and analyzed blood samples for alcohol. A consulting psychiatrist interviewed each patient before discharge to evaluate potential SI or suicide attempt (SA) using structured and semi-structured scales. Of the 120 patients 20% had SI or had made a SA. High psychological distress in girls, low blood alcohol levels (BALs), as well as low scores on self-esteem, on social support and on familial support were associated with patients with SI/SA. Logistic regression showed that the most significant variables with suicidal patients included low BAL and low self-esteem and high alcohol consumption. Psychological distress had a direct and mediational role in the suicidal patients. Adolescents referred to the pediatric emergency department with intoxication displaying high psychological distress and low self-esteem represent a high-risk group of teens. In this group, careful assessment of mental health status, screening for suicidal ideation, and SAs seems warranted.

    The objective of this study was to explore the optimum combination of micronutrients used with 2,3-dimercaptosuccinic acid (DMSA) in the treatment of moderately lead-intoxicated mice. Experiment was carried out based on the orthogonal design L{sub 8}(2{sup 7}) setting six factors with two different levels of each, and eight groups of mice were needed. Mice were exposed to lead by drinking water contaminated with 0.1% lead acetate for four consecutive weeks, and then supplemented by gavage with different combinations of micronutrients with and without DMSA as designed in the orthogonal table. Lead levels in blood, liver, kidney, brain and bone and activities of blood {delta}-aminolevulinic acid dehydratase (ALAD) were analyzed after cessation of supplementation. The results suggested that DMSA was the only factor which could decrease significantly lead levels in blood, liver, kidney and bone; calcium and ascorbic acid were the notable factors decreasing lead levels in blood, liver, kidney, bone and brain; zinc and calcium were the notable factors reversing the lead-inhibited activities of blood ALAD; taurine was the notable factor decreasing lead levels in kidney and brain; and thiamine was the notable factor decreasing lead levels in brain. The lowest lead level in blood, liver, kidney and bone was shown in the mice supplemented with combination of calcium and ascorbic acid along with DMSA. In conclusion, the optimum combination of micronutrients used with DMSA suggested in present study was calcium and ascorbic acid, which seemed to potentiate the chelating efficacy of DMSA in the treatment of moderately lead intoxicated mice.

Since human umbilical cord stem cells have been shown to provide neuroprotection and promote neural regeneration, we have attempted to transplant the human umbilical cord blood mononuclear cells (hUCB-MNCs to treat patients with delayed encephalopathy after carbon monoxide intoxication (DEACOI. The hUCB-MNCs were isolated from fresh umbilical cord blood and were given to patients subarachnoidally. Physical examinations, mini-mental state examination scores, and computed tomography scans were used to evaluate the improvement of symptoms, signs, and pathological changes of the patient's brain before and after hUCB-MNC transplantation. A total of 12 patients with DEACOI were treated with hUCB-MNCs in this study. We found that most of the patients have shown significant improvements in movement, behavior, and cognitive function, and improved brain images in 1–4 months from the first transplantation of hUCB-MNCs. None of these patients have been observed to have any severe adverse effects. Our study suggests that the hUCB-MNC transplantation may be a safe and effective treatment for DEACOI. Further studies and clinical trials with more cases, using more systematic scoring methods, are needed to evaluate brain structural and functional improvements in patients with DEACOI after hUCB-MNC therapy.Keywords: human umbilical cord blood mononuclear cells, transplantation, delayed encephalopathy after carbon monoxide intoxication, MMSE

    Experimental laboratory studies suggest that the approach bias (relatively fast approach responses) toward substance-related materials plays an important role in problematic substance use. How this bias is moderated by intention to use versus recent use remains unknown. Moreover, the relationship between approach bias and other motivational processes (satiation and craving) and executive functioning remains unclear. The aim of this study was to investigate the cannabis approach bias before and after cannabis use in real-life setting (Amsterdam coffee shops) and to assess the relationship between approach bias, craving, satiation, cannabis use, and response inhibition. Cannabis, tobacco, and neutral approach and avoidance action tendencies were measured with the Approach Avoidance Task and compared between 42 heavy cannabis users with the intention to use and 45 heavy cannabis users shortly after cannabis use. The classical Stroop was used to measure response inhibition. Multiple regression analyses were conducted to investigate relationships between approach bias, satiation, craving, cannabis use, and response inhibition. In contrast to the hypotheses, heavy cannabis users with the intention to use did not show a cannabis approach bias, whereas intoxicated cannabis users did show an approach bias regardless of image category. This could be attributed to a general slowing of avoidance action tendencies. Moreover, craving was negatively associated with the approach bias, and no relationships were observed between the cannabis approach bias, satiation, prior cannabis use, and response inhibition. Cannabis intoxication in a real-life setting inhibited general avoidance. Expression of the cannabis approach bias appeared not to be modulated by satiation or response inhibition.

  7. Treatment of Arsenite Intoxication-Induced Peripheral Vasculopathy with Mesenchymal Stem Cells

    2018-03-01

    Full Text Available Arsenite (As, a notorious toxic metal, is ubiquitously distributed in the earth and poses a serious threat to human health. Histopathological lesions of As intoxication are known as thromboangiitis obliterans, which are resistant to current treatment and often lead to lower limb amputation. In this study, we attempt to find that treatment with mesenchymal stem cells (MSCs may be effective for As-induced vasculopathy. We first conducted an in vitro study with a co-culture system containing human MSCs and human umbilical vein endothelial cells (HUVECs and treated individual and co-cultured cells with various concentrations of arsenite. We also designed an in vivo study in which Sprague Dawley (SD rats received periodic intraperitoneal (IP injections of 16 ppm arsenite for 12 weeks. MSCs were harvested from BALB/c mice that were transplanted via tail vein injection. We found that there was significantly higher cellular viability in human mesenchymal stem cells (hMSCs than in HUVECs under concentrations of arsenite between 15 and 25 μM. The Annexin V apoptosis assay further confirmed this finding. Cytokine array assay for As-conditioned media revealed an elevated vascular endothelial growth factor (VEGF level secreted by MSCs, which is crucial for HUVEC survival and was evaluated by an siRNA VEGF knockdown test. In the in vivo study, we demonstrated early apoptotic changes in the anterior tibial vessels of As-injected SD rats with a Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL assay, but these apoptotic changes were less frequently observed upon MSCs transplantation, indicating that the cytoprotective effect of MSCs successfully protected against As-induced peripheral vasculopathy. The feasibility of MSCs to treat and /or prevent the progression of As-induced vasculopathy is justified. Further clinical studies are required to demonstrate the therapeutic efficacy of MSCs in patients suffering from As intoxication with

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

    Lead (Pb)-induced neurodegeneration and its link with widespread neurobehavioral changes are well documented. Experimental evidences suggest that ethanol could enhance the absorption of metals in the body, and alcohol consumption may increase the susceptibility to metal intoxication in the brain. However, the underlying mechanism of ethanol action in affecting metal toxicity in brain cells is poorly understood. Thus, an attempt was made to investigate the modulatory effect of ethanol on Pb intoxication in PC12 cells, a rat pheochromocytoma. Cells were co-exposed to biological safe doses of Pb (10 μM) and ethanol (200 mM), and data were compared to the response of cells which received independent exposure to these chemicals at similar doses. Ethanol (200 mM) exposure significantly aggravated the Pb-induced alterations in the end points associated with oxidative stress and apoptosis. The finding confirms the involvement of reactive oxygen species (ROS)-mediated oxidative stress, and impairment of mitochondrial membrane potential, which subsequently facilitate the translocation of triggering proteins between cytoplasm and mitochondria. We further confirmed the apoptotic changes due to induction of mitochondria-mediated caspase cascade. These cellular changes were found to recover significantly, if the cells are exposed to N-acetyl cysteine (NAC), a known antioxidant. Our data suggest that ethanol may potentiate Pb-induced cellular damage in brain cells, but such damaging effects could be recovered by inhibition of ROS generation. These results open up further possibilities for the design of new therapeutics based on antioxidants to prevent neurodegeneration and associated health problems.

    Between November 2007 and March 2008, 18 children died from a rapidly progressive central nervous system disease of unexplained origin in a community involved in the recycling of used lead-acid batteries (ULAB) in the suburbs of Dakar, Senegal. We investigated the cause of these deaths. Because autopsies were not possible, the investigation centered on clinical and laboratory assessments performed on 32 siblings of deceased children and 23 mothers and on 18 children and 8 adults living in the same area, complemented by environmental health investigations. All 81 individuals investigated were poisoned with lead, some of them severely. The blood lead level of the 50 children tested ranged from 39.8 to 613.9 microg/dL with a mean of 129.5 microg/dL. Seventeen children showed severe neurologic features of toxicity. Homes and soil in surrounding areas were heavily contaminated with lead (indoors, up to 14,000 mg/kg; outdoors, up to 302,000 mg/kg) as a result of informal ULAB recycling. Our investigations revealed a mass lead intoxication that occurred through inhalation and ingestion of soil and dust heavily contaminated with lead as a result of informal and unsafe ULAB recycling. Circumstantial evidence suggested that most or all of the 18 deaths were due to encephalopathy resulting from severe lead intoxication. Findings also suggest that most habitants of the contaminated area, estimated at 950, are also likely to be poisoned. This highlights the severe health risks posed by informal ULAB recycling, in particular in developing countries, and emphasizes the need to strengthen national and international efforts to address this global public health problem.

    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.

  12. Fatal intoxication as a consequence of intranasal administration (snorting) or pulmonary inhalation (smoking) of heroin.

    In recent years we have noticed an increasing proportion of mortalities resulting from an overdose of heroin that involve routes of administration other than injection. Of 239 cases of fatal heroin intoxication examined at our department during the period 1997-2000, 18 deaths were associated with non-parental administration. Seven of these fatalities were experienced heroin users who had begun to use more sporadically, seven were recreational "party-users", while the remaining four persons had relapsed into heroin use following long periods of abstinence. The median blood morphine concentration of these non-injectors was 0.095 microg/g (range: 0.02-0.67 microg/g), significantly lower than that of the injectors. Concurrent use of alcohol, other illicit drugs and/or pharmaceutical preparations was observed in 17 of the 18 cases. However, there were no statistically significant differences between the victims of heroin intoxication by injection or by other routes with respect to the proportion who had simultaneously consumed alcohol or benzodiazepines. Pathological alterations like lung fibrosis, liver cirrhosis, endocarditis, etc. were not found to play a significant role in any of the 18 mortalities. We conclude that snorting or smoking heroin probably involves a reduced risk of obtaining high blood concentrations of morphine but still constitutes a considerable risk of lethal outcome due to high variability in blood concentrations. Furthermore, decreased tolerance resulting from periods of reduced or sporadic use appears to be an important risk factor in connection with heroin overdosing by snorting or smoking, which indicate that some heroin addicts may inaccurately assume that these routes of administration are safe when resuming their use of heroin after a period of abstinence.

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

    The aim of this study is to examine methyl alcohol poisoning cases from the medico-legal point of view. The records of the Morgue Department of Council of the Forensic Medicine were reviewed retrospectively for all methyl alcohol poisonings for the period of 27.10.1992 and 30.05.2001. The victim's age, sex, death year, death place, methyl alcohol blood levels, the source of methyl alcohol, accompanying laboratory results and histopathologic tissue changes were recorded. The number of deaths due to the methyl alcohol poisoning was 271 during that period of time. Two hundred and forty-two of the (89.3%) total 271 methyl alcohol fatalities were men and 29 (10.7%) of were women. The largest age group was 36-40 years old, followed by 41-45. The methyl alcohol blood concentrations ranged widely from 50 to 755 mg for per 100 ml. There were 222 cases (81.9%) with the methyl alcohol blood concentrations over 100 mg/dl. Twenty-nine (10.7%) victims were poisoned through the consumption of cologne and three of them with alcoholic beverage named "Raki". Consumed products were not known in all other cases because of insufficient patient history and data. As a conclusion, regarding the distribution according to years, mortality due to methyl alcohol intoxication in our country have been proceeding on a certain level. In order to decrease the mortality due to methyl alcohol intoxication, some precautions should be developed that could prevent the production and consumption of alcoholic beverages illegally produced.

    Prior neuroimaging evidence indicates that decision conflict activates medial and lateral prefrontal and parietal cortices. Theoretical accounts of cognitive control highlight anterior cingulate cortex (ACC) as a central node in this network. However, a better understanding of the relative primacy and functional contributions of these areas to decision conflict requires insight into the neural dynamics of successive processing stages including conflict detection, response selection and execution. Moderate alcohol intoxication impairs cognitive control as it interferes with the ability to inhibit dominant, prepotent responses when they are no longer correct. To examine the effects of moderate intoxication on successive processing stages during cognitive control, spatio-temporal changes in total event-related theta power were measured during Stroop-induced conflict. Healthy social drinkers served as their own controls by participating in both alcohol (0.6 g/kg ethanol for men, 0.55 g/kg women) and placebo conditions in a counterbalanced design. Anatomically-constrained magnetoencephalography (aMEG) approach was applied to complex power spectra for theta (4-7 Hz) frequencies. The principal generator of event-related theta power to conflict was estimated to ACC, with contributions from fronto-parietal areas. The ACC was uniquely sensitive to conflict during both early conflict detection, and later response selection and execution stages. Alcohol attenuated theta power to conflict across successive processing stages, suggesting that alcohol-induced deficits in cognitive control may result from theta suppression in the executive network. Slower RTs were associated with attenuated theta power estimated to ACC, indicating that alcohol impairs motor preparation and execution subserved by the ACC. In addition to their relevance for the currently prevailing accounts of cognitive control, our results suggest that alcohol-induced impairment of top-down strategic processing

    The possibility of long-term grape juice concentrate (GJC) consumption conferring a protective effect against cadmium (Cd)-induced damage to the epididymis, completely preserving sperm profile, was evaluated here for the first time in the scientific literature. Male Wistar rats (n = 6/per group) received an intraperitoneal Cd injection (1.2 mg/Kg) at age 80 days and GJC (2 g/Kg) by gavage from 50 days until 136 days old. Groups receiving either Cd or GJC were added. An intraperitoneal injection of saline (0.9%) and water by gavage was administered in the absence of treatment with Cd or GJC. Animals were anaesthetized and exsanguinated at 136 days; the vas deferens, left testis and epididymis were removed; and perfusion continued with fixative. The right epididymis was collected for morphological analysis. Cd had a devastating effect demonstrated by reduced sperm count in testes and epididymis, sperm production and normal sperm count, besides increased epididymis sperm transit time and completely disorganized morphology. These alterations were attributed to higher Cd levels in the testes and a lipid peroxidation (LP) process. Consumption of GJC plus Cd intoxication was effective, reducing metal accumulation and LP. Consequently, we could identify a preserved sperm profile, with improvement in testis and epididymis sperm count, normal sperm structure and sperm transit time. Moreover, GJC extends its protective effect to the epididymis, allowing complete re-establishment of its morphology, ensuring successful sperm maturation process. In conclusion, our study indicates long-term GJC as a promising therapy against reproductive chemical intoxication injury damage, preserving sperm prior to ejaculation. © 2017 The Authors.

    Intoxication by pods of Prosopis juliflora (mesquite beans) causes an impairment of cranial nerve function in cattle and goats. In goats, vacuolation of neurons in the trigeminal motor nuclei has been reported. To study the lesions in cattle caused by consumption of P. juliflora pods and dry ground pods, eight 6- to 12-month-old male cattle were divided into 4 groups: group 1 was fed a ration containing 50% of pods; groups 2 and 3 received a ration containing 50 and 75% of dry ground pods, respectively; group 4 was the control. After 200 days, all cattle were killed and sampled for histologic evaluation. Samples of the trigeminal motor nucleus were examined by electron microscopy. All cattle from groups 1, 2, and 3 showed clinical signs resulting from impaired function of cranial nerves V, IX, X, and XII, starting 45-75 days after consumption of the plant. The main histologic lesions were vacuolation and loss of neurons in trigeminal motor nuclei and other motor cranial nerve nuclei with Wallerian-like degeneration in the cranial nerves. Mild denervation atrophy was observed in the masseter and other masticatory muscles. On electron microscopy, neurons of the trigeminal nuclei had markedly swollen mitochondria, with the mitochondrial cristae displaced peripherally, disoriented and disintegrating. Intoxication by P. juliflora seems to have a novel pathogenesis, characterized by a selective, primary, chronic, and progressive injury to mitochondria of neurons of the trigeminal and other cranial nerve nuclei. Cranial nerve degeneration and denervation atrophy of the muscles occurs as a consequence of the neuronal lesion.

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

  19. Risk factors for unnatural death: Fatal accidental intoxication, undetermined intent and suicide: Register follow-up in a criminal justice population with substance use problems.

    Risk factors for suicide and fatal accidental intoxication are extensively studied, while risk factors for intoxications/injuries of undetermined intent are less well known. The latter have shown an overlap with suicides, but also with fatal accidental intoxications. The objective was to analyze potential differences and similarities in the patterns of risk factors for accidental intoxications, injuries/intoxications with undetermined intent, and suicides, respectively. A follow-up register study was conducted, using data from ASI interviews with clients in the criminal justice system in Sweden (n=6744), followed in the National Causes of Death Register. A set of risk factors from the ASI interview were tested in bivariate analysis with the respective cause of death, yielding significant risk factors further analyzed in three Cox regression models. In Cox regression analyses, death from fatal accidental intoxication was associated with male gender (HR 4.09), use of heroin (HR 2.86), and use of cannabis (HR 1.94), and death from intoxication/injury of undetermined intent was associated with use of heroin (HR 3.48), binge drinking of alcohol (HR 2.46) and previous psychiatric hospitalization (HR 2.41), while negatively associated with depression (HR 0.33). Death from suicide was associated with previous suicide attempts (HR 2.78) and use of sedatives (HR 2.17). In this population of criminal justice clients with reported substance use problems, fatal injuries/intoxications with undetermined intent - like fatal accidental intoxications - appear to be associated with substance use variables, and cannot readily be assumed to represent the same background factors as suicide.

  20. Oral manifestations of lupus.

    Menzies, S; O'Shea, F; Galvin, S; Wynne, B

    2018-02-01

    Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. A total of 42 patients were included. The majority of patients were female (88%) and had a diagnosis of discoid lupus erythematosus (62%). Half of the patients had positive oral findings, 26% had no oral examination documented, and 24% had documented normal oral examinations. Our findings suggest that oral pathology is common in this cohort of patients. Regular oral examination is warranted to identify oral lupus and provide treatment. Associated diseases such as Sjogren's syndrome may also be identified. Patients should be encouraged to see their general dental practitioners on a regular basis for mucosal review. Any persistent ulcer that fails to respond to treatment or hard lump needs urgent histopathological evaluation to exclude malignant transformation to squamous cell carcinoma.

  2. Radiation induced oral mucositis

    P S Satheesh Kumar

    2009-01-01

    Full Text Available Patients receiving radiotherapy or chemotherapy will receive some degree of oral mucositis The incidence of oral mucositis was especially high in patients: (i With primary tumors in the oral cavity, oropharynx, or nasopharynx; (ii who also received concomitant chemotherapy; (iii who received a total dose over 5,000 cGy; and (iv who were treated with altered fractionation radiation schedules. Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene

    Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect.

  4. Towards understanding oral health.

    Zaura, Egija; ten Cate, Jacob M

    2015-01-01

    During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

  5. Global Oral Health Inequalities

    Garcia, I.; Tabak, L.A.

    2011-01-01

    Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be “at the table” with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

  6. Oral microbiota and cancer

    Jukka H. Meurman

    2010-08-01

    Full Text Available Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion.

  8. Oral candidosis in relation to oral immunity.

    Feller, L; Khammissa, R A G; Chandran, R; Altini, M; Lemmer, J

    2014-09-01

    Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern-recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL-1β, IL-6 and IL-23. These cytokines induce the differentiation of Th17 cells and the generation of IL-17- and/or IL-22-mediated antifungal protective immuno-inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL-17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern-recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern-recognition receptors (TLR2, TLR4, Dectin-1 and Dectin-2). IL-17-mediated protective immune response is essential for oral mucosal immunity to C. albicans infection. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  15. The volume of Purkinje cells decreases in the cerebellum of acrylamide-intoxicated rats, but no cells are lost

    Larsen, Jytte Overgaard; Tandrup, T; Braendgaard, H

    1994-01-01

    The effects of acrylamide intoxication on the numbers of granule and Purkinje cells and the volume of Purkinje cell perikarya have been evaluated with stereological methods. The analysis was carried out in the cerebella of rats that had received a dose of 33.3 mg/kg acrylamide, twice a week, for 7.......5 weeks. The total numbers of cerebellar granule and Purkinje cells were estimated using the optical fractionator and the mean volume of the Purkinje cell perikarya was estimated with the vertical rotator technique. The volumes of the molecular layer, the granular cell layer and the white matter were...... estimated using the Cavalieri principle. The mean weight of the cerebellum of the intoxicated rats was 7% lower than that of the control rats (2P = 0.001). The numbers of the Purkinje cells and granule cells were the same in both groups, but the mean volume of the perikarya of the Purkinje cells...

  16. Carbon dioxide poisoning: a literature review of an often forgotten cause of intoxication in the emergency department.

    Permentier, Kris; Vercammen, Steven; Soetaert, Sylvia; Schellemans, Christian

    2017-12-01

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

  17. Psychogenic Polydipsia: The Result, or Cause of, Deteriorating Psychotic Symptoms? A Case Report of the Consequences of Water Intoxication

    Melissa Gill

    2015-01-01

    Full Text Available Water intoxication is a rare condition characterised by overconsumption of water. It can occur in athletes engaging in endurance sports, users of MDMA (ecstasy, and patients receiving total parenteral nutrition. This case outlines water intoxication in a patient with psychogenic polydipsia. When the kidney’s capacity to compensate for exaggerated water intake is exceeded, hypotonic hyperhydration results. Consequences can involve headaches, behavioural changes, muscular weakness, twitching, vomiting, confusion, irritability, drowsiness, and seizures. Cerebral oedema can lead to brain damage and eventual death. In this case, psychogenic polydipsia led to significant hyponatraemia, cerebral oedema, and tonic-clonic seizures. Differential diagnoses for hyponatraemia are outlined. The aetiology of psychogenic polydipsia is uncertain, but postulated hypotheses are explored. Psychogenic polydipsia occurs in up 20% of psychiatric patients and this case serves to remind us to be cognizant of water overconsumption.

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

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

    1984-12-01

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