Acute alcohol intoxication occurs in elderly subjects. Drunkenness appears in banal clinical forms in geriatrics: falls, dizziness or confusion. Elderly people are more vulnerable to alcohol and need less alcohol to become intoxicated. Age does not exclude the possibility of receiving alcohol addiction treatment. Broaching the subject with an elderly person, the day after a drunken episode, is useful and recommended. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Alcohol is used in most cultures despite knowledge of the physical, psychological and social problems associated with its abuse. Behavioural impairment is a function of several factors, including blood alcohol concentration (BAC) and the rate of alcohol metabolism by alcohol dehydrogenase and the microsomal ethanol-oxidizing system. Their availability and activity depend upon alcohol use history, ethnicity, other drug use and gender. Adverse social consequences related to alcohol intoxication include impaired driving, acts of aggression and violence towards self and others, and various types of accidents. About 40% of all fatal traffic accidents in Canada and the US in 1986-1987 were alcohol-related. Similar statistics have been reported in the UK and Europe (e.g. Sweden). The risk of a fatal car accident increases exponentially with a driver's BAC, prompting recommendations to lower the legal BAC limit for driving and piloting aircraft. Risks of falls, drownings, and fires and burns may also be increased by alcohol intoxication. At least 22% of work-related accidents may have involved alcohol use. These data are probably conservative estimates as under-reporting of alcohol use is likely. Alcohol facilitates aggressive behaviours, but it is difficult to separate the pharmacological effect from psychosocial effects or some other common factor (e.g. low CSF levels of the serotonin metabolite 5-H1AA have been reported in alcoholics, suicide attempters, violent offenders). In addition, alcohol interacts with other drugs to increase or decrease their behavioural and therapeutic effects. An acutely high BAC inhibits the metabolism of other CNS depressants (e.g. benzodiazepines), but long-term alcohol use increases the metabolism of most drugs. A potential amethystic agent, to block or reverse alcohol's effects, has been identified in preclinical studies (Ro15-4513, an imidazobenzodiazepine). Some clinical studies indicated that naloxone, lithium, ibuprofen, zimeldine and

In clinical practice, poisoning with ethylene glycol, methanol, and isopropyl alcohol is common. These alcohol-related intoxications can present with high anion gap metabolic acidosis and increased osmolality. Toxicity and clinical symptoms are due to the accumulation of their metabolites, causing increased anion gap, rather than the parent compounds that are associated with an increase of serum osmolality. Clinical manifestations result from abnormalities of neurologic, cardiopulmonary, and renal function. Laboratory abnormalities when present are helpful for diagnosis but may be absent depending on the time of ingestion and time of presentation. Fomepizole and ethanol are potent inhibitors of alcohol dehydrogenase and reduce generation of toxic metabolites. Hemodialysis is an effective way of detoxification because it can remove unmetabolized alcohol in addition to the organic anions. High index of suspicion and early diagnosis can prevent the significant morbidity and mortality associated with these intoxications.

Full Text Available Introduction: 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. Methods: 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. Results: 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. Conclusion: 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.

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.

Memory affects behavior by allowing events to be anticipated and goals to be planned based on previous experiences. Emotional memory, in particular, is thought to play a central role in behavior in general and in drinking behavior in particular. Alcohol intoxication has been shown to disrupt intentional, conscious memory, but not unintentional, implicit memory for neutral stimuli; however, its effects on emotional memory are not well understood. This study examined whether alcohol intoxication affected memory for emotionally valenced stimuli by testing explicit recall and implicit repetition priming of emotional picture cues. Participants were 36 young adults (21-24 years old, 16 women) who received an alcohol, placebo, or no-alcohol beverage. Both cue exposure and memory testing occurred after beverage consumption (i.e., during intoxication for the alcohol group). Alcohol intoxication impaired explicit recall of all cue types but did not impair implicit repetition priming. Emotionally negative and positive cues were more often recalled compared with neutral cues across all beverage groups, and emotionally negative cues demonstrated more priming than emotionally positive or neutral cues in all beverage groups. Alcohol intoxication disrupted effortful recall of all cues, although the relative memory advantage of emotionally valenced over-neutral stimuli remained even after drinking. The effects of alcohol on unintentional memory priming were not statistically significant, but the effects of emotionally negative cues were. Further research is needed to better understand alcohol intoxication and emotional valence effects on memory processes during implicit memory tasks and the possibility that negative mood facilitates memory priming of negative emotional stimuli.

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%.

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

Anecdotal reports link alcohol intoxication to creativity, while cognitive research highlights the crucial role of cognitive control for creative thought. This study examined the effects of mild alcohol intoxication on creative cognition in a placebo-controlled design. Participants completed executive and creative cognition tasks before and after consuming either alcoholic beer (BAC of 0.03) or non-alcoholic beer (placebo). Alcohol impaired executive control, but improved performance in the Remote Associates Test, and did not affect divergent thinking ability. The findings indicate that certain aspects of creative cognition benefit from mild attenuations of cognitive control, and contribute to the growing evidence that higher cognitive control is not always associated with better cognitive performance.

Methanol, ethylene glycol, and diethylene glycol intoxications can produce visual disturbances, neurological disturbances, acute renal failure, pulmonary dysfunction, cardiac dysfunction, metabolic acidosis, and death. Metabolic acidosis and an increased serum osmolality are important clues to their diagnosis. The former reflects the organic acids produced by metabolism of the parent alcohol, while the latter is due to accumulation of the offending alcohol. However, neither the clinical nor the laboratory findings are specific for toxic alcohol ingestions. The definitive diagnosis of the alcohol intoxications is commonly based on detection of the alcohol or its metabolites in blood. Early diagnosis is important, because initiation of appropriate treatment can markedly lessen their morbidity and mortality. At present detection of the parent alcohol in body fluids is inferred from its measurement in blood. This measurement is often performed by specialty laboratories using expensive equipment, and a long delay between obtaining the specimen and getting the results is not unusual. In this report, we describe liquid- based tests that detect methanol, ethylene glycol, diethylene glycol, and ethanol in saliva. The tests are sensitive and they have different specificity for each of the alcohols facilitating distinction among them. The relatively high sensitivity and specificity of the tests as a whole will facilitate the rapid diagnosis of each of these alcohol intoxications. PMID:18940722

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

Intoxications with ethylene glycol, methanol, and isopropanol are among the most common ingestions, in the treatment of which a nephrologist plays an important role. These three substances have the ideal characteristics for intervention by hemodialysis, and the three parent compounds and their metabolites are readily dialyzable. Two of the three substances, ethylene glycol and methanol, are metabolized to more toxic substances, so that an early treatment strategy that removes the parent compound or blocks its metabolism can prevent the development of many of the adverse events that are often seen in these ingestions. Fomepizole, an inhibitor of alcohol dehydrogenase, slows the metabolism of these substances and is now approved by the US Food and Drug Administration for use in ethylene glycol intoxication. The present review addresses recent advances in the diagnosis and treatment of intoxication with ethylene glycol, methanol and isopropanol.
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.

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

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.

A number of studies have shown that stress and an activated hypothalamic-pituitary-adrenal (HPA) axis are associated with increased voluntary alcohol drinking. Recently, associations have been found between activated HPA and hypothalamic-pituitary-gonadal (HPG) axes in alcohol-preferring AA and non-preferring ANA, F2 (crossbred second generation from original AA and ANA), and Wistar rats. The aim of the present study has been to determine the role of corticosterone and alcohol-related testosterone-effects in subsequent alcohol drinking in AA, ANA, F2 and Wistar rats. The present study comprises of four substudies presenting new analyses of existing data, by which correlations between basal corticosterone levels, changes in testosterone levels during alcohol intoxications and subsequent voluntary alcohol consumption are investigated. The results displayed positive correlations between basal corticosterone levels and subsequent alcohol-mediated testosterone elevations, which was positively associated with voluntary alcohol consumption. The results also showed a negative correlation between basal corticosterone levels and alcohol-mediated testosterone decreases, which was negatively associated with alcohol consumption. In conclusion, the present study displays novel results, according to which the HPA axis, one hand, relates to testosterone elevation (potentially causing and/or strengthening reinforcement) during alcohol intoxication, which in turn may relate to higher voluntary alcohol consumption (AA rats). Vice versa, the HPA axis may also relate to alcohol-mediated testosterone decrease (causing testosterone reduction and disinforcement) and low-alcohol drinking (ANA, F2 and Wistar rats). In addition, the present results showed that alcohol-mediated testosterone changes may also, independently of the HPA axis, correlate with voluntary alcohol drinking, which indicate the impact of genetic factors. Thus, the role of the HPA-axis may be more related to situational

Both drinking location and pregaming have been associated with heavy alcohol use among college students, yet the manner by which they uniquely contribute to alcohol intoxication remains unclear. The current study examined the unique utility of drinking location and pregaming in predicting alcohol intoxication among college students who violated campus alcohol policy. Between 2011 and 2012, mandated college students who reported drinking prior to their referral events (N = 212, 41% female, 80% White, Mage = 19.4 y) completed a computerized assessment of drinking location and related behaviors as part of larger research trial. Chi-squared statistics, t-tests, one-way analyses of covariance, and regression were used to examine study aims. Participants were most likely (44%) to report drinking in off-campus housing prior to the referral event, and approximately half (47%) reported pregaming. Alcohol intoxication on the night of the referral event differed significantly as a function of both drinking location and pregaming, but pregaming did not moderate the association between drinking location and alcohol intoxication among mandated students. Female birth sex, pregaming, and drinking at either fraternities or off-campus housing predicted greater levels of alcohol intoxication on the night of the referral incident, while drinking in a residence hall/dorm predicted lower intoxication. Drinking location and pregaming are distinct predictors of alcohol intoxication among mandated college students. Future interventions may benefit from targeting both where and how college students consume alcohol.

We report a series of studies examining the effect of alcohol mixed with energy drinks (AmEDs) versus alcohol on objective intoxication (breath alcohol concentration; BrAC), intensity, and nature of intoxication. We also aimed to disentangle the role of energy drink (ED) ingredients in any effects. Three within-subject double-blind placebo-controlled studies measured BrAC, subjective intoxication and impairment ('intensity of intoxication'), stimulation and sedation ('nature of intoxication') following administration of ED, Cola, Caffeine+Sugar, and Placebo with alcohol (Study 1, n=18); ED, Caffeine-only, Sugar-only and Placebo with alcohol (Study 2, n=20); and ED and Placebo with alcohol (Study 3, n=27). Significant moderate-to-large magnitude BrAC decrements and delayed time to peak BrAC were observed after ED administration versus Placebo. However, no meaningful BrAC differences between ED and other active conditions were observed in Study 1 and 2. After BrAC adjustment, moderate-to-large magnitude reductions in intoxication and impairment ratings were observed after ED versus Placebo on the ascending limb in all studies and at peak in Study 2 and 3. No meaningful differences were observed in intoxication and impairment ratings between ED and Caffeine+Sugar and Cola conditions (Study 1); ratings were lower after ED versus Sugar-only (Study 2). Stimulation and sedation ratings did not differ between ED and Placebo. Reductions in objective intoxication and perceived intensity of intoxication, but not nature of intoxication, were observed after AmED consumption. However, effects may be common to alcohol mixers containing sugars (objective intoxication) and caffeine (intensity of intoxication) and specific to a laboratory setting. Copyright © 2017.

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 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.

Alcohol-related problems at professional sporting events are of increasing concern and alarming reports are often reported in international media. Although alcohol consumption increases the risk for interpersonal violence, it is viewed as a focal element of large football events. Sweden has a long tradition of high public support for strict alcohol-control policies. However, little is known about public opinions on alcohol intoxication and the support for interventions to decrease intoxication at football events. The current study explored the public opinion towards alcohol use, intoxication and alcohol policies at professional football matches in Sweden. A cross-sectional design was utilized and a random general population sample of 3503 adult Swedish residents was asked to participate in a web survey during 2016 (response rate 68%). In total, 26% of the respondents supported alcohol sales at football events. Over 90% reported that obviously intoxicated spectators should be denied entrance or evicted from arenas. The support for regulations limiting alcohol availability varied with background factors such as gender, alcohol use and frequency of football event attendance. There is a strong public consensus for strategies and policies to reduce alcohol sales and intoxication levels at football matches. This public support has implications for our preventive efforts and will facilitate the implementation of strategies and policy changes.

In recent years, there has been increasing concern about youthful "binge" drinking and intoxication. Yet the meaning of intoxication remains under-theorized. This paper examines intoxication in a young adult nightlife scene, using data from a 2005-2008 National Institute on Drug Abuse-funded project on Asian American youth and nightlife. Analyzing in-depth qualitative interview data with 250 Asian American young adults in the San Francisco area, we examine their narratives about alcohol intoxication with respect to sociability, stress, and fun, and their navigation of the fine line between being "buzzed" and being "wasted." Finally, limitations of the study and directions for future research are noted.

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.

Aims: Although the relationship between the Y90 (blood alcohol concentration, BAC) and Y91 (clinician intoxication assessment) ICD-10 codes has received attention recently, the role of 10 signs of intoxication in the Y91–Y90 relationship has not been studied yet. This work examines these signs in the estimation of alcohol intoxication levels of patients in medical settings. Methods: Collected and analyzed were data on 1997 injured emergency room patients from 17 countries worldwide reporting drinking prior to injury or presenting with a non-zero BAC from 17 countries worldwide. A model is estimated describing how the 10 signs inform the Y91, Y90 prediction with the goal of the use of observations on patients in place of a biological measure. Results: Signs were consistent with a single underlying construct that strongly predicted Y91. Smell of alcohol on breath predicted Y91 above its contribution through the construct and was stronger for those with tolerance to alcohol than for those without. Controlling for Y91, no sign further contributed to prediction of Y90 indicating that Y91 incorporated all intoxication sign information in predicting Y90. Variance explained was high for Y91 (R2 = 0.84) and intoxication signs (above 0.72 for all but smell on the breath, 0.57) and lower for Y90 (0.38). Conclusion: Intoxication assessments are well predicted by overall intoxication severity, which itself is well represented by intoxication signs along with differential emphasis on smell of alcohol on breath, especially for those with alcohol tolerance. However, BAC levels remain largely unexplained by intoxication signs with a clinician's assessment serving as the primary predictive measure. PMID:24705784
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.

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.

Background The goal of this study was to examine the latent structure among measures of alcohol-induced subjective feelings of intoxication from a behavioral pharmacology perspective. Methods Data on subjective intoxication, measured concomitantly by the Subjective High Assessment Scale (SHAS), Biphasic Alcohol Effect Scale (BAES), and the Short-Version of the Profile of Mood States (POMS), were collected at three levels of breath alcohol concentration (BrAC) during an alcohol administration study in a sample of heavy drinkers (n = 135). Results Results of exploratory factor analyses supported a three-factor model which captured the following dimensions of subjective intoxication: (a) stimulation and other pleasant effects; (b) sedative and unpleasant effects; and (c) alleviation of tension and negative mood. The tension-reduction factor was most consistently associated with more frequent drinking and alcohol problems in this sample. Conclusions These findings support the notion that the neuropharmacological and behavioral effects of alcohol are multifaceted and cannot be simply defined as either positive or negative. Rather, moderate levels of intoxication appear to have concomitant dimensions of positive reinforcement, negative reinforcement, and punishment. This study also suggests that factor scores may be useful in future alcohol administration studies in order to reduce the number of comparisons and perhaps increase statistical power to detect meaningful effects.

Environmental factors inside licensed venues have been found to influence the intoxication levels and consumption practices of patrons. The consumption of alcohol mixed with energy drinks (AmED) occurs primarily at or prior to attending licensed venues, however there is a lack of in situ research investigating AmED use in these contexts. Given that AmED use has been linked with increased alcohol consumption, intoxication, illicit substance use, and risk taking behaviours, this paper explores the environmental correlates and levels of intoxication associated with AmED use in licensed venues. Structured observations were undertaken in five Australian cities on Friday and Saturday nights. Covert teams spent 4-5h in venues and recorded hourly observations on patron, venue, and staff characteristics, alcohol, illicit drug and AmED consumption patterns and intoxication levels. 898 hourly observations were recorded across 68 venues. All but one venue served energy drinks, and patron AmED use was observed during 34.9% of hourly records. AmED use was more prevalent after 12am and in nightclub venues compared to bars and pubs, and was positively associated with high intoxication levels, illicit drug use, and younger crowds. After controlling for environmental factors (i.e. venue crowding, service practices, venue characteristics, patron demographics and behaviour) AmED use did not predict high intoxication at a venue level in multivariable models. AmED consumption is ubiquitous in the licensed venues of Australian night-time entertainment districts, particularly busy nightclub venues where intoxication and risky consumption are heightened. However, AmED use was not associated with high patron intoxication when environmental factors were considered. Copyright © 2016 Elsevier B.V. All rights reserved.

Salivary lactoferrin is a glycoprotein involved in the elimination of pathogens and the prevention of massive overgrowth of microorganisms that affect oral and general health. A high concentration of lactoferrin in saliva is often considered to be a marker of damage to the salivary glands, gingivitis, or leakage through inflamed or damaged oral mucosa, infiltrated particularly by neutrophils. We conducted a study to determine the effect of chronic alcohol intoxication on salivary lactoferrin concentration and output. The study included 30 volunteers consisting of ten non-smoking male patients after chronic alcohol intoxication (group A, and 20 control nonsmoking male social drinkers (group C with no history of alcohol abuse. Resting whole saliva was collected 24 to 48 hours after a chronic alcohol intoxication period. Lactoferrin was assessed by enzyme-linked immunosorbent assay. For all participants, the DMFT index (decayed, missing, or filled teeth, gingival index (GI and papilla bleeding index (PBI were assessed. The differences between groups were evaluated using the Mann–Whitney U test. We noticed significantly decreased salivary flow (SF in alcohol dependent patients after chronic alcohol intoxication (A, compared to the control group (C. Although there was no significant difference in salivary lactoferrin concentration between the alcohol dependent group A and the control group C, we found significantly decreased lactoferrin output in group A compared to group C. We found a significant correlation between the amount of daily alcohol use and a decrease in lactoferrin output. There was a significant increase in GI and a tendency of PBI to increase in group A compared to group C. We demonstrated that chronic alcohol intoxication decreases SF and lactoferrin output. The decreased lactoferrin output in persons chronically intoxicated by alcohol may be the result of lactoferrin exhaustion during drinking (due to its alcohol-related lower

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

Full Text Available Background Several field studies have used fuel-cell breathalysers (FCB to investigate the prevalence of alcohol intoxication. However, there is a lack of evidence evaluating the psychometric properties of these breathalysers outside of the forensic disciplines. Methods The current research describes four studies designed that assess the reliability and validity of portable platinum FCBs for research on alcohol intoxication. Utilising the Alcolizer LE5 breathalyser and, to a lesser degree, the Lifeloc FC-20 and the Lion Intoxilyzer 8000, each study sampled patrons frequenting popular night-time entertainment districts with varying levels of alcohol intoxication. Results Study one and two found excellent test-retest reliability and inter-instrument reliability for FCBs. Study three and four provided evidence to support the convergent validity of the two FCBs (the LE5 with the FC20, and with an evidential breathalyser (i.e., the Lion Intoxilyzer 8000; EB. Discussion A 93–97% agreement rate between breathalyser readings was found across the four studies. Portable FCB are recommended as a reliable and valid instrument for research designs requiring quick alcohol intoxication estimations in large populations. Strategies to enhance reliable and valid readings are provided for field researchers.

The analysis of injuries of floating crew of the Northern water pool in a state of alcoholic intoxication havebeen based on the 180 accidents on board of ships with temporary loss of ability to work, and 1686 casehistories with alcoholic injuries, which demanded treatment in a surgical department. Among persons,the received injuries on the ship in the state of alcoholic intoxication were 8.1% of the victims: in thestrength of the transport fleet - 8.9%; fishing - 8.9% and river ones - 4.1%. Masters of fish production,skippers, rulers of the radio stations and masters of fish processing were most frequently injured afterthe consumption of the alcoholic beverages. Alcoholic injuries have been recorded at the time of walkingon the catwalk and the decks (54.2%), mooring operations (15.1%), maintenance and repairing the deckmachinery, water preparation (6.6%), as well as boat and loading-unloading works (4.3%). Falls from heightconstituted 36.6% of the injuries. Alcohol in 3.2 times increases the weight of the combined injuries. Thedeaths from the alcohol related injuries in marine conditions (43.4%) significantly exceed the indicators inthe group of non-alcoholic injuries (7.0%). Alcoholic intoxication has been noted in 35.0% of the cases ofthe floating crew injuries, hospitalised in the surgical department. Victims with alcoholic injuries receivedduring performing ship's works were hospitalised 10 times less, than those with non-productive types ofinjuries. In the structure of non-industrial injuries, household injuries prevail (78.2%) over those receiveddue to falls on the street, in pedestrian flows (10.3%), transport and traffic accidents (6.7%), intentionalinjuries (4.1%) or those connected with sports games and competitions (0.7%). Fishermen are a professionalgroup of seamen, subject to the high social vulnerability to the alcoholic beverages consumptionand related injuries.

This study investigates the effects of alcohol, drug intoxication and withdrawal symptoms on the mental state of criminal suspects and the nature of their confession. A total of 359 sentenced prisoners were approached on admission and 96% agreed to participate in the study. They completed a specially designed Confession Questionnaire, which asked them questions about their reasons for confessing to the police, their attitude towards their confession, their mental state at the time of the confession and the extent to which they had been under the influence of alcohol and drug intoxication at the time of crime and police interview. The confession rate for the sample was very high (92%), with serious traffic violators having the highest confession rate (95%) and sex offenders the lowest (83%). The findings illustrate that the "perception of proof", "internal need to confess" and "external pressure" are the main reasons why suspects confess. However, subjects were identified who had experienced a typical "prisoner's dilemma" phenomenon during the police interview because of a co-defendant. Alcohol and drug intoxication was very commonly reported both at the time of the offence and the police interview, but these were related to the nature of their offence. Although intoxication and withdrawal symptoms did not appear to seriously impair their coping during the police interview it was consistently reported as having made them confused.

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.

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. 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. 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. 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.

Ethanol is commonly overused psychoactive substance in Poland and all around the world. It causes addiction, which occurs as a result of its chronic administration. One of the main symptoms of addiction is hunger due to psychoactive substance that prevents interruption of its adoption and contributes to relapse drinking. Acute poisoning with ethyl alcohol and alcohol withdrawal syndrome are diseases causing a potential danger to life. The prevalence of use and abuse of alcoholic beverages is a potential risk, causing health problems, including permanent damage of the central and peripheral nervous system and socio-economic problems. The aim of this study is to analyze certain aspects of the socio-economic situation of the patients hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome in 2010. 299 patients history was evaluated, among which 161 were treated for acute intoxication with ethanol and 138 due to alcohol withdrawal syndrome. Objects of interest were elements of subjective tests including: marital status of patients, their education and professional activity and the problem of homelessness. The study group consisted of 299 patients in age from 16 to 77 years, hospitalized in the Department of Toxicology in Raszeja City Hospital in Poznan due to acute ethanol intoxication or alcohol withdrawal syndrome. It was found that the largest group consisted of patients remaining married (42.81%) and unmarried (30.43%). Alcohol abuse affects people of all levels of education. In the present study, most patients had a vocational education (37.79%) and medium (23.08%). Patients were analyzed in terms of economic activity, among which about 40% were unemployed. In the whole group more than 10% of those were homeless. Ethyl alcohol intoxication and alcohol withdrawal represents a significant hazard. As a result of reliance, patients lose control of alcohol consumption and they
Full Text Available AIM: During forensic-medical autopsies experts must very often assess degree and the role of acute alcohol intoxications in mechanisms of death. This becomes more actual in the cases of sudden death from different diseases especially cardiac, brain and liver origin, mechanical injuries, mechanical asphyxia etc. METHOD: This study aims to show that blood concentration of alcohol must not be only criteria during assessment of severity of intoxications and their influence on patogenesis. Epidemiological screening of 320 medico-legal reports assesses the role of sex, age, ethnicity and other peculiarities. RESULTS: Special histochemical investigations of ethanol oxidizing enzymes were also conducted on materials taken from 167 autopsies. CONCLUSION: Study suggests that morpho-functional histochemical tests must be entered in the list of methods of postmortem diagnostics during autopsies of cases with the background of ethanol poisoning, especially for differential diagnosis of acute alcohol intoxication, alcohol cardiomyopathy and ischemic heart disease.

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

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 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.

This study draws on Finkel and Eckhardt's (2013) I³ framework to examine the interactive effects of 2 emotion regulation strategies-anger rumination (an impellance factor) and reappraisal (an inhibition factor), and alcohol intoxication (a disinhibition factor)-on intimate partner aggression (IPA) perpetration as measured with an analogue aggression task. Participants were 69 couples recruited from a large Midwestern university (total N = 138). Participants' trait rumination and reappraisal were measured by self-report. Participants were randomized individually to an alcohol or placebo condition, then recalled an anger event while using 1 of 3 randomly assigned emotion regulation conditions (rumination, reappraisal, or uninstructed). Following this, participants completed an analogue aggression task involving ostensibly assigning white noise blasts to their partner. Participants in the alcohol condition displayed greater IPA than participants in the placebo condition for provoked IPA, but not unprovoked IPA. Results also revealed interactions such that for those in the alcohol and rumination group, higher trait reappraisal was related to lower unprovoked IPA. For provoked IPA, higher trait rumination was related to greater IPA among those in the alcohol and rumination condition and those in the placebo and uninstructed condition. In general, results were consistent with I³ theory, suggesting that alcohol disinhibits, rumination impels, and trait reappraisal inhibits IPA. The theoretical and clinical implications of these findings are discussed in the context of current knowledge about the influence of alcohol intoxication and emotion regulation strategies on IPA perpetration.

Gluteal compartment syndrome is a relatively rare condition that mostly result from atraumatic causes such as prolonged immobilization due to drug abuse or alcoholic intoxication and incorrect positioning during surgical procedures rather than traumatic causes. Early diagnosis is difficult and sometimes delayed or overlooked because of poor physical signs resulting from altered mental status and inappropriate diagnosis by clinicians. It has been reported that more than half of the cases of gluteal compartment syndrome are associated with crush syndrome and sciatic nerve palsy. Early diagnosis and immediate fasciotomy are necessary to improve the functional prognosis. Here, we report the case of a patient with gluteal compartment syndrome caused by prolonged immobilization after acute alcoholic intoxication. After disease onset, the patient developed complications of crush syndrome and sciatic nerve palsy, but immediate fasciotomy improved his condition.

The prevalence of adolescents hospitalized with acute alcohol intoxication, mainly because of severe reduced consciousness, is increasing. However, the characteristics of these adolescents are mainly unidentified. In this clinical research, we aimed to identify factors that attribute to higher ethanol concentration, on which targeted alcohol health interventions can be designed. Since 2007, alcohol intoxication among adolescents has been one of the leading topics of the Dutch Pediatric Surveillance System. In the current study, we have analyzed which demographic characteristics, general alcohol use behaviors, and clinical intoxication data were related to the blood alcohol concentration (BAC) levels at hospital admittance. We included all adolescents aged 0.0 g/l, and reduced consciousness during the years 2007, 2008, 2009, and 2010. A total of 2,023 adolescents with alcohol intoxication were reported, and 1,618 questionnaires were returned, of which 1,350 met our inclusion criteria. In univariate analysis, age, gender, educational level, place of alcohol purchase, place of alcohol consumption, age of first drink, and regular alcohol use during the weekend correlated with higher BAC. After multivariate analysis, older adolescents, boys, and higher educational level significantly attributed to higher BAC at admittance. In alcohol-intoxicated adolescents with reduced consciousness, gender, age, and also educational level correlate with BAC at admittance. Explanatory factors could be found in sensitivity to alcohol, but also in socioeconomic factors, which influence availability. Intervention strategies could be targeted more specific now for the subgroups found in this study to decrease the growing burden of adolescent alcohol intoxication, both on the societal level and on the clinical level.

Recent research has shown that alcohol consumption can exacerbate expressions of racial bias by increasing reliance on stereotypes. However, little work has investigated how alcohol affects intergroup evaluations. The current work sought to address the issue in the context of the correspondence between implicit and explicit measures of anti-black attitudes. Participants were randomly assigned to consume an alcoholic (target BAC of 0.08%), placebo, or control beverage prior to completing implicit and explicit measures of racial attitudes. Although beverage condition did not affect prejudice levels on either measure, it did change the correlation between them. Implicitly measured attitudes significantly predicted explicit reports of prejudice and discrimination only for participants who consumed alcohol. We discuss the implications of our findings for debates regarding dissociations between implicit and explicit measures and the cultural phenomenon of intoxicated individuals attributing prejudiced statements to alcohol consumption rather than personal attitudes.

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.

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.

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

Objectives Although it is well known that people with alcohol dependence are at a markedly elevated risk for suicide, much less is known about the role of acute alcohol use in suicidal behaviours. The primary aims of this epidemiological study were to assess the prevalence and factors associated with acute alcohol intoxication among 57 813 suicide decedents in 16 states. Methods Data from the restricted National Violent Death Reporting System 2003–2009 for male and female suicide decedents aged 18 years and older were analysed by multiple logistic regression to compare decedents with and without acute alcohol intoxication (defined as blood alcohol concentration (BAC) ≥0.08 g/dl). Results Among men, those who were younger, American Indian/Alaska Native, Hispanic, veterans, of lower educational attainment, deceased from a self-inflicted firearm injury or hanging/suffocation and residing in rural areas were more likely to have been intoxicated at the time of death. Among women, the factors associated with a BAC ≥0.08 g/dl were younger age, being American Indian/Alaska Native, and using a firearm, hanging/suffocation or falling as method of death. Conclusions In both men and women, alcohol intoxication was associated with violent methods of suicide and declined markedly with age, suggesting that addressing risks associated with acute alcohol use may be of the greatest aid in the prevention of violent suicides among young and middle age adults.

Alcohol intoxication is associated with socially disinhibited behaviours that may reflect impaired social cognitive abilities that guide social behaviour. The effects of alcohol on social cognition and how this may contribute to disinhibited behaviour are poorly understood. The aim of this study was to examine whether intoxicated individuals could inhibit automatic negative responses to negative social information, whether these difficulties were reliant on theory of mind (ToM) ability and whether intoxicated individuals were able to adjust verbal responses when provided with guidelines about how to respond. Sixty-four participants aged between 18 and 34 (balanced for gender) consumed a beverage containing either placebo or alcohol calculated to achieve a target BrAC of 0.080%, before completing a Flanker task, a go/no-go task and a novel measure of social disinhibition, the social disinhibition task. Results indicate that alcohol-intoxicated individuals can inhibit negative responses to negative social information, but display difficulty inhibiting negative responses to social information that requires ToM. They also suggest that people under the influence of moderate-to-high-dose alcohol can adjust their responses when provided with specific guidelines on how to respond. These findings may have important implications for understanding negative alcohol-related behaviours and promote the consideration of social context, social pressure and social cognitive abilities in the development of public policy and targeted interventions to prevent alcohol-related antisocial behaviours.

Driving while intoxicated is a major public health problem. We investigated impaired driving using a simulated driving skill game that presents an 'in-car' view of a road and a readout of speed. We explored brain activation and behavioral alterations from baseline at two blood alcohol concentrations (BACs). Participants received single-blind individualized doses of beverage alcohol designed to produce blood alcohol content (BAC) of 0.04 and 0.08 or placebo. Scanning occurred on a 1.5 Tesla Philips MRI scanner after training to asymptote performance. Analysis was performed using independent component analysis (ICA) to isolate systematically nonoverlapping 'networks' and their time courses. Imaging results revealed seven separate driving-related brain networks with different time courses. Several significant findings were observed for the imaging data. First, dose-dependent functional magnetic resonance imaging (fMRI) changes were revealed in orbitofrontal (OF) and motor (but not cerebellar) regions; visual and medial frontal regions were unaffected. Second, cerebellar regions were significantly associated with driving behavior in a dose-dependent manner. Finally, a global disruptive effect of alcohol on the ICA time courses was observed with highly significant differences in OF and motor regions. Alcohol thus demonstrated some behavioral effects and unique, disruptive, dose-dependent effects on fMRI signal within several brain circuits. The fMRI data also suggest that the deficits observed in alcohol intoxication may be modulated primarily through OF/anterior cingulate, motor and cerebellar regions as opposed to attentional areas in frontoparietal cortex.

The combination of highly caffeinated "energy drinks" with alcohol (ethanol [EtOH]) has become popular among young adults and intoxication via such beverages has been associated with an elevated risk for harmful behaviors. However, there are discrepancies in the human literature regarding the effect of caffeine on alcohol intoxication, perhaps due to confounding factors such as personality type, expectancy, and history of exposure. Animal models of co-exposure are resistant to such issues; however, the consequences of voluntary co-consumption have been largely ignored in the animal literature. The primary goal of this work was to characterize a mouse model of binge caffeine and EtOH co-consumption employing the limited access "Drinking-in-the-Dark" (DID) paradigm. Caffeine was added to a 20% alcohol solution via DID. Alcohol/caffeine intake, locomotor behavior, ataxia, anxiety-like behavior, and cognitive function were evaluated as a consequence of co-consumption in adult male C57BL/6J mice. Caffeine did not substantially alter binge alcohol intake or resultant blood EtOH concentrations (BECs), nor did it alter alcohol's anxiolytic effects on the elevated plus maze or cognitive-interfering effects in a novel object-recognition task. However, no evidence of alcohol-induced sedation was observed in co-consumption groups that instead demonstrated a highly stimulated state similar to that of caffeine alone. The addition of caffeine was also found to mitigate alcohol-induced ataxia. Taken together, our mouse model indicates that binge co-consumption of caffeine and alcohol produces a stimulated, less ataxic and anxious, as well as cognitively altered state; a state that could be of great public health concern. These results appear to resemble the colloquially identified "wide awake drunk" state that individuals seek via consumption of such beverages. This self-administration model therefore offers the capacity for translationally valid explorations of the

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

Drawn from a study aimed at exploring students' drinking behaviour and attitudes, this article focuses upon findings that revealed how heavy-drinking students monitored and managed their experiences of alcohol intoxication. 819 students residing within three university student residences were invited to participate in three phases of data collection. Utilising a combination of qualitative and quantitative research methods, a total of 15 focus group interviews and 18 indepth interviews were undertaken, and 501 students (61%) completed a written survey questionnaire. Sixty percent of students agreed with the statement "I usually know beforehand if I am going to get drunk". One-half of male drinkers and one-third of female drinkers reported they were intoxicated on a weekly basis. When drinking to intoxication, the majority of students monitored a range of drinking effects (a total of 14 were identified) which they considered were signals for the need to either slow down or stop drinking. The majority of drinkers in this study who consume alcohol with the intention of getting intoxicated, typically drink to a predetermined level of intoxication, and maintain that level by monitoring a range of drinking effects--this behaviour has been termed controlled intoxication. Future harm-minimisation strategies could be developed that encourage heavy-drinkers to adopt 'safer' drinking-effect signals as indicators to slow down or stop drinking.

Drinking at an early age (AO) and quickly progressing to drinking to intoxication (Delay=Age of Intoxication[AI]-AO) confer risk for alcohol use and alcohol-related problems. However, inconsistencies exist in the literature, which may reflect the use of different definitions of AO and AI. We evaluated whether 1) defining AO as age at first sip of alcohol (AO sip) versus age at which at least one standard drink was consumed (AO drink); and 2) defining AI as age at first "drunk" (AI drunk) versus age at first binge episode (≥5 standard drinks consumed; AI binge) resulted in different self-reported ages or differentially predicted drinking outcomes. 248 high school students (53.6% male; 16.50[1.19] years; 71.4% White) completed anonymous surveys assessing alcohol use. Participants reported a younger AO (sip) than AO (drink) and a younger AI (drunk) than AI (binge), resulting in significantly different Delay values for the four AO-AI pairings. Univariate general linear models indicated that AO-Delay pairings accounted for more variance in maximum drinks and alcohol-related problems than did the individual AO and AI variables. Pairings comprising AO (drink) and Delay (drink-binge) and AO (sip) and Delay (sip-binge), respectively, uniquely accounted for variance in both maximum drinks and problems. Clearly defining AO and AI using objective definitions that reflect specific amounts of alcohol (e.g., first sip; first standard drink; first binge) appears to outperform subjective definitions of alcohol use (e.g., first drunk).

We previously reported the deleterious effects of acute alcohol intoxication (AAI) on pituitary-gonadal and pituitary-adrenal axes hormones in human adolescents. In the present paper we studied the effects of AAI on the growth axis hormones, and the possible contribution of the insulin-glucose axis to the alcohol-induced dysfunction of the growth axis in human adolescents. Blood samples were drawn from adolescents that arrived at the emergency department with evident behavioural symptoms of drunkenness (AAI) or with nil consumption of alcohol (controls [C]). AAI produced in the adolescents of both sexes in our series: a decrease in growth hormone (GH) levels, without significant alteration of either insulin-like growth factor-I (IGF-I) or insulin-like growth factor binding protein-3 (IGFBP3); an increase in plasma glucose and a decrease in insulin in the female adolescents but not in the males. Males and females undergo a significant period of bone growth during adolescence. Growth axis hormones play an important role in the pubertal spurt. Thus, ethanol consumption during adolescence could have long-lasting deleterious effects on this aspect of development. In industrialised countries, around 35% of alcohol drinkers are under 16 years old, therefore the result of this study should be made known to adolescents and the appropriate authorities.

Overservice of alcohol (i.e., selling alcohol to intoxicated patrons) continues to be a problem at bars and restaurants, contributing to serious consequences such as traffic crashes and violence. We developed a training program for managers of bars and restaurants, eARM™, focusing on preventing overservice of alcohol. The program included online and face-to-face components to help create and implement establishment-specific policies. We conducted a large, randomized controlled trial in bars and restaurants in one metropolitan area in the midwestern United States to evaluate effects of the eARM program on the likelihood of selling alcohol to obviously intoxicated patrons. Our outcome measure was pseudo-intoxicated purchase attempts-buyers acted out signs of intoxication while attempting to purchase alcohol-conducted at baseline and then at 1 month, 3 months, and 6 months after training. We conducted intention-to-treat analyses on changes in purchase attempts in intervention (n = 171) versus control (n = 163) bars/restaurants using a Time × Condition interaction, as well as planned contrasts between baseline and follow-up purchase attempts. The overall Time × Condition interaction was not statistically significant. At 1 month after training, we observed a 6% relative reduction in likelihood of selling to obviously intoxicated patrons in intervention versus control bars/restaurants. At 3 months after training, this difference widened to a 12% relative reduction; however, at 6 months this difference dissipated. None of these specific contrasts were statistically significant (p = .05). The observed effects of this enhanced training program are consistent with prior research showing modest initial effects followed by a decay within 6 months of the core training. Unless better training methods are identified, training programs are inadequate as the sole approach to reduce overservice of alcohol.

The consumption of alcohol mixed with energy drinks (AmED) has become a popular and controversial practice among young people. Increased rates of impaired driving and injuries have been associated with AmED consumption. The purpose of this study was to examine if the consumption of AmED alters cognitive processing and subjective measures of intoxication compared with the consumption of alcohol alone. Eighteen participants (nine men and nine women) attended four test sessions where they received one of four doses in random order (0.65 g/kg alcohol, 3.57 ml/kg energy drink, AmED, or a placebo beverage). Performance on a psychological refractory period (PRP) task was used to measure dual-task information processing and performance on the Purdue pegboard task was used to measure simple and complex motor coordination following dose administration. In addition, various subjective measures of stimulation, sedation, impairment, and level of intoxication were recorded. The results indicated that alcohol slowed dual-task information processing and impaired simple and complex motor coordination. The coadministration of the energy drink with alcohol did not alter the alcohol-induced impairment on these objective measures. For subjective effects, alcohol increased various ratings indicative of feelings of intoxication. More importantly, coadministration of the energy drink with alcohol reduced perceptions of mental fatigue and enhanced feelings of stimulation compared to alcohol alone. In conclusion, AmED may contribute to a high-risk scenario for a drinker. The mix of behavioral impairment with reduced fatigue and enhanced stimulation may lead AmED consumers to erroneously perceive themselves as better able to function than is actually the case.

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.

Alcohol addiction develops through a series of stages, and mechanistic studies are needed to understand the transition from initial drug use to sustained controlled alcohol consumption followed by abuse and physical dependence. The focus of this study was to examine the effects of voluntary alcohol consumption on brain gene expression profiles using a mouse model of binge drinking. The main goal was to identify alcohol-responsive genes and functional categories after a single episode of drinking to intoxication. We used a modification of a "Drinking In the Dark" (DID) procedure (Rhodes et al., 2005) that allows mice to experience physiologically relevant amounts of alcohol in a non-stressful environment and also allows for detection of alcohol-sensitive molecular changes in a dose-dependent manner. C57BL/6J male mice were exposed to either 20% ethanol solution or water (single bottle) starting 3 hours after lights off for 4 hours and brains were harvested immediately after the drinking session. cDNA microarrays were used to assess the effects of voluntary drinking on global gene expression in 6 brain regions. We employed three statistical approaches to analyze microarray data. A commonly used approach that applies a strict statistical threshold identified the eight top statistically significant genes whose expression was significantly correlated with blood ethanol concentration (BEC) in one of the brain regions. We then used a systems network approach to examine brain region-specific transcriptomes and identify modules of co-expressed (correlated) genes. In each brain region, we identified alcohol-responsive modules, i.e., modules significantly enriched for genes whose expression was correlated with BEC. A functional over-representation analysis was then applied to examine the organizing principles of alcohol-responsive modules. Genes were clustered into modules according to their roles in different physiological processes, functional groups, and cell types

Few studies have explored the epidemiology of students presenting to the emergency department (ED) as a consequence of hazardous drinking. This study examined differentials and trends in ED visits following alcohol intoxication and co-occurring conditions among students presenting to a major U.S. university health system. The ED electronic medical records from academic years 2010-2015 were queried for student visits and their records were linked to the university's student admission datasets. Student alcohol-related visits were identified based on ICD-9 codes. Student characteristics and trends in the rate of alcohol intoxication per 100 ED student visits were analyzed. A random sample of 600 student clinical records were reviewed to validate diagnostic codes. There were 9616 student ED visits (48% males) to the ED of which 1001 (10.4%) visits involved alcohol intoxication. Two thirds of ED visits with alcohol intoxication had a co-occurring diagnosis, with injuries (24%) being the most common condition. The rate of alcohol intoxication varied greatly by student demographics and campus-related factors. There was a linear increase in the rate of alcohol intoxication from 7.9% in 2009-10 to 12.3% in 2014-15 (pstudents, students below 20 years of age, Asian students, and student athletes. In the sample reviewed, only two thirds of ED visits with alcohol intoxication were recorded by diagnostic codes. The rate of ED visits following alcohol intoxication varied by student demographic characteristics and campus-related factors with a rising trend over the study period. Copyright © 2017 Elsevier B.V.

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.

Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. The identification of acute alcohol intoxication is extremely important, as well as the alcohol withdrawal syndrome and its complications, such as delirium tremens and Wernicke's encephalopathy in order to grant a timely treatment for those patients. This article introduces the evidence found so as to face and treat these clinic manifestations. Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. Evidence was found and recommendations were made for the diagnosis and treatment of acute alcohol intoxication, withdrawal syndrome, delirium tremens and Wernicke's encephalopathy.

The alcohol drinking at the young age is a risk factor of alcohol addiction later in life, and is connected with school problems, binge drinking, tobacco addiction, illegal drug use, violence, crime commitment, and risky sexual behaviors. Alcohol drinking in the last 12 months is declared by 78% Polish children. The aim of the study was to evaluate the frequency of admissions due to alcohol intoxication to the Department of Pediatrics, Pediatric Endocrinology and Diabetes, Pediatric Center of Silesia and the identification of the risk factors of the acute alcohol intoxication among Polish children and adolescents. Ten-year retrospective study includes investigation of patients medical records from the Department of Pediatrics. Among 8048 patients hospitalized in the Department of Pediatrics between the years 2000-2010, 220 (2.7%) cases of acute alcohol poisoning occurred The detailed data analysis from 139 patients [66 (47.5%) girls, 73 (52,5%) boys] was done. In the years 2006-2010 the number of girls admitted to the department increased in comparison to boys. The largest group of patients was at age between 14 and 16 years [61 (44%) children]. The blood alcohol concentration at the moment of admission to the hospital was 0.1 to 4.0 per thousand. In most cases (92.8%) the alcohol intoxication was intentional. Five percent of them were suicide attempts. In the youngest group of children alcohol abuse was unintentional. 23 (16.5%) of patients initially needed admission to the intensive care unit. In 30 (21.6%) patient the family was incomplete and five times more often father was absent. The alcohol addiction occurs in 18 (13.0%) fathers and 10 (7.2%) mothers of our patients. It is concluded that over the last decade the number of girls admitted due to alcohol abuse increased. Children at school grade between 7-9 are intoxicated most often. One six of intoxicated patents needed hospitalization at intensive care unit.
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…

Full Text Available The article deals with description of morphological alterations in lungs and their autonomic ganglia due to chronic alcohol intoxication caused by compulsory ethanol ingesting in Wistar rats. Progressive decrease of air content, superficial density of bronchial and alveolar epithelia, and the increase of quantitative density of bronchial and alveolar macrophages became quantitative morphological evidence of chronic lung injury. At the same time, in autonomic ganglia of lungs the volume fraction and quantitative density of neurons decreased dramatically and the characteristics of neurons in radial morphometry were altered. The quantitative density of glial cells and glia/neuron ratio were increased. The total loss of neurons in ganglia reached 7 % to the 60th day of experiment, the signs of compensatory reactions were revealed simultaneously. These peculiarities can particularly explain the mechanisms of chronic lung pathology in late stages of alcohol disease.

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

To extend previous research demonstrating that intoxicated men high in hostility toward women report stronger intentions to use coercive condom use resistance (CUR) tactics to have unprotected sex by examining the role of women's condom request style. Community, non-problem drinking men, ages 21-30 ( N = 296) completed standard alcohol administration procedures and read an eroticized story of a casual sexual interaction. Following the woman's request to use a condom, intentions to engage in coercive CUR tactics were assessed. Generalized linear models with gamma distributions assessed the 3-way interaction of men's hostility toward women, beverage condition (alcohol or sober), and the woman's condom request style (indirect, direct, or insistent). The 3-way interaction between hostility toward women, beverage condition, and indirect condom request (vs. direct) significantly predicted men's coercive CUR intentions. Men high in hostility toward women reported stronger CUR intentions after experiencing an indirect condom request, when sober or intoxicated, and after a direct condom request when intoxicated. Men high in hostility toward women reported the weakest CUR intentions when sober following an insistent or direct condom request. Men high in hostility toward women pose a threat to women's sexual safety, particularly when intoxicated or following an indirect condom request. Hostility toward women and alcohol consumption should be addressed in sexual risk prevention programs. Pending further replication, women should be informed of the relative effectiveness of using insistent condom requests.

Adolescence is a period of multiple changes where social behaviors influence interpersonal-relations. Adolescents live new experiences, including alcohol consumption which has become an increasing health problem. The age of onset for consumption has declined in the last decades, and additionally, the adolescents now uptake greater amounts of alcohol per occasion. Alcohol consumption is a risk factor for accidents, mental illnesses or other pathologies, as well as for the appearance of addictions, including alcoholism. An interesting topic to study is the damage that alcohol induces on the central nervous system (CNS) in the young population. The brain undergoes substantial modifications during adolescence, making brain cells more vulnerable to the ethanol toxicity. Over the last years, the brain mitochondria have emerged as a cell organelle which is particularly susceptible to alcohol. Mitochondria suffer severe alterations which can be exacerbated if the amount of alcohol or the exposure time is increased. In this review, we focus on the changes that the adolescent brain undergoes after drinking, placing particular emphasis on mitochondrial damage and their consequences against brain function. Finally, we propose the mitochondria as an important mediator in alcohol toxicity and a potential therapeutic target to reduce or treat brain conditions associated with excessive alcohol consumption. © 2017 Wiley Periodicals, Inc.
Full Text Available Abstract Background The aims of this study were to describe alcohol use among Norwegian teenagers and investigate the associations between mental health problems and alcohol intoxications with focus on age and gender. Methods Population based, cross-sectional survey addressing all adolescents aged 13–19 years, attending secondary or high school in North – Trøndelag County, Norway. 8983 youths (91% answered the Young-HUNT questionnaire in the 1995–1997 survey. Logistic regression models were used to study associations. Results 80% of the respondents reported that they had tried drinking alcohol, and 57% had been intoxicated at least once. The proportion of the students, which had tried alcohol, was equal in both genders and increased with age. Attention problems and conduct problems were strongly associated with frequent alcohol intoxications in both genders. Anxiety and depressive symptoms among girls were also related to high numbers of intoxications Conclusion Gender differences in number of alcohol intoxications were small. There was a close association between both conduct and attention problems and high alcohol consumption in both genders. Girls with symptoms of anxiety and depression reported more frequent alcohol intoxications.

This study reports the results of a pilot program in Kenosha County that used a combination of direct biomarkers extracted from blood spots and nails to monitor repeat intoxicated drivers for their use of alcohol and drugs with a detection window spanning from 3 weeks to several months. The objectives were to test whether the direct biomarkers phosphatidylethanol (PEth), ethylglucuronide (EtG), and 5 drug metabolites would (1) help assessors obtain a more objective evaluation of repeat offenders during the assessment interview, (2) allow for timely identification of relapses and improve classification of drivers into risk categories, and (3) predict recidivism by identifying offenders most likely to obtain a subsequent operating while intoxicated (OWI) offense within 4 years of enrollment in the program. All (N = 261) repeat offenders were tested using PEth obtained from blood spots and EtG obtained from fingernails; 159 participants were also tested for a 5 drugs of abuse nail panel. Drivers were tested immediately after the assessment interview (baseline) and at 3, 6, 9, and 12 months after baseline. Based on biomarker results and self-reports of abstinence, offenders were classified into different risk categories and required to follow specific testing timelines based on the program's decision tree. The baseline analysis shows that 60% of drivers tested positive for alcohol biomarkers (EtG, PEth, or both) at the assessment interview, with lower detection rates (0-11%) for the 5 drug metabolites. The comparison of biomarkers results to self-reports of abstinence identified 28% of all offenders as high risk and assigned them to more frequent testing and more intense monitoring. The longitudinal analysis shows that 56% (completers) of participants completed the program successfully and the remaining 44% (noncompliant) terminated prematurely. Two thirds (68%) of the completers were able to reduce or control their drinking and one third relapsed at least one time
Full Text Available Vehicle-related injuries are the major cause of death and injuries in Hualien County, and driving under the influence of alcohol plays a major role in such crashes. From December 1997 to May 1998, we determined the blood alcohol concentrations (BAC of injured individuals from vehicle crashes at two emergency departments in Hualien. Nurses were asked to record whether the patient presented with an alcohol odor. The accuracy of detection by nurses was assessed from the BAC and groups with increased prevalence were identified for screening. Of 945 patients assessed, 505 (53.4% tested positive by BAC and 320 (33.9% were identified with an alcohol odor. With a BAC threshold of more than 50 mg/dL, detection sensitivity was 75.4%, specificity was 90.4%, and accuracy was 85.0% (95% confidence interval: 82.7, 87.3. Patients with an alcohol odor were significantly more likely to be men, aborigines, or head-injured patients. The accuracy of detection showed no significant difference by gender, head injury, or driver status. We suggest that detection of alcohol odor by nurses may be a feasible assessment of the role of alcohol in road traffic accidents. This may provide essential data for injury prevention strategies and programs.

As part of its investigation of the EXXON VALDEZ tankship accident and oil spill, the National Transportation Safety Board (NTSB) examined the master's speech for alcohol-related effects. Recorded speech samples were obtained from marine radio communications tapes. The samples were tested for four effects associated with alcohol consumption is available scientific literature: slowed speech, speech errors, misarticulation of difficult sounds ("slurring"), and audible changes in speech quality. It was found that speech immediately before and after the accident displayed large changes of the sort associated with alcohol consumption. These changes were not readily explained by fatigue, psychological stress, drug effects, or medical problems. Speech analysis appears to be a useful technique to provide secondary evidence of alcohol impairment.

26 of serious inedible alcohol (ethylene glycol and methanol) intoxications have been observed in Lublin Regional Center of Clinical Toxicology during 2010/2011 (18 mounths). As a result of such intoxications, metabolic acidosis and acute renal failure and other organs injury develop. The writings inform that it is possible to survive a pH spectrum between 6.8 and 7.8, whereas beyond these values protein denaturation and death proceed. The paper presents two cases of intoxication with ethylene glycol and ethylene glycol, methanol together where the lowest pH values in capillary blood were recorded below 6.8. The first case is of a male, 45, who was diagnosed glycol concentration at 283.3 mg/dl, with the lowest pH value obtained in the gasometric examination of capillary blood at 6.712. The other case is of another male, 54, who had probably drunk condenser liquid. Ethylene glycol and methanol's concentration were 535 mg/dl and 37.5 mg/dl correspondingly, whereas the lowest capillary blood pH value was recorded at 6.745. Both men had been addicted to alcohol for many years. The treatment demanded multiple hemodialyses, respiratory therapy, catecholamine intravenous injections as well as intensive pharmacological treatment resulting from multi-organ complications. The intoxication in either case was non-lethal.

Alcohol consumption may lead to deficits in the executive functions that govern self-regulation. These deficits could lead to risk-taking behaviors; therefore, it is important to determine the magnitude of these deficits on executive functioning. The purpose of this experiment was to investigate the acute effects of alcohol on three of the executive functions that are hypothesized to affect self-regulation, which are inhibition, set shifting, and working memory, using a mixed-methods study design. The participants were 75 moderate or heavy drinkers between the ages of 21 and 35 who were randomized into one of three beverage conditions (control, placebo, or 0.65-g alcohol dose/kg body weight). Performance on working memory, set shifting, and inhibition were measured pre- and post-beverage consumption. The results showed only a significant interaction in the working memory data, as there was an increase in performance post-beverage relative to pre-beverage for the control participants as compared to the alcohol and placebo participants. It was concluded that the dose of alcohol (BAC = 0.063%) given to moderate to heavy drinkers was not sufficient to cause significant impairment in the executive functions tested. The results were further discussed and methodological concerns were considered, such as the low BAC achieved, practice effects, and insensitivity of tasks. Copyright © 2017 Elsevier Inc.

Full Text Available Alcoholism is one of the most frequent dependences among people, leading to damage of the liver and death of the person. Chronic alcohol consumption decreases fatty acid oxidation by interfering with carnitine metabolism and citric acid cycle activity. Block in activity of the citric acid cycle caused by alcohol and its metabolites is partially compensated by increased ketone body production, which results in ketosis. Chronic administration of alcohol induces liver injury, inflammation, cirrhosis, focal necrosis and steatosis.L-carnitine (L-3-hydroxy-4-N, N, N-trimethylaminebutyric acid is an essential factor in fatty acid metabolism, which plays a major role in transport of activated long-chain fatty acids to sites of β-oxidation in mitochondria. Carnitine also stabilizes cell membranes by removing long-chain acyl-CoA and excess of the acyl group from the body. L-carnitine can be a useful and safe drug in the liver pathology induced by chronic ethanol exposure.

Based upon a functional approach to understanding aggression, we aimed to identify the occurrence of and to describe the features of three types of alcohol-related violence defined a priori by ultimate goals: (1) violence in pursuit of nonsocial profit-based goals, (2) violence in pursuit of social dominance goals, and (3) violence as defence in response to threat. A sample of 149 young men with offences of violence that were alcohol related was interviewed. Cases were classified and detailed information from the first ten cases in each class (N=30) was subjected to thematic analysis. Intoxicated violence in pursuit of nonsocial profit-based goals was opportunistic and motivated by the desire for more alcohol or drugs. Violence, in these cases, although serious, appeared to be brief. Intoxicated violence in pursuit of social dominance goals was typically precipitated by past or current insult or injury, and was accompanied by strong anger and an adrenaline rush. Attacks were ferocious, and robbing the victim was not uncommon, perhaps to inflict additional humiliation. Feelings of pride and satisfaction were typical and expressions of remorse were uncommon. Regarding intoxicated violence as defence in response to threat, attacks were often expected, and in some cases the respondent made a pre-emptive strike. Weapon use was common in this group. Fear was experienced, but so too was anger. Feelings of excitement were not reported and remorse was common. Further validation of these types is warranted, and the potential implications of these findings for prevention and treatment are discussed.

Objective Prior research on the effects of sexual trauma has examined dissociation but not emotional numbing during sex and has relied exclusively on retrospective surveys. The present experiment examined associations among distal factors of childhood sexual abuse (CSA), adolescent/adult sexual assault (ASA), and trauma symptoms and the proximal factor of acute alcohol intoxication on in-the-moment dissociation, emotional numbing, and sexual risk intentions. Method Young adult female drinkers (N = 436) at elevated sexual risk were randomized to receive alcohol (target peak breath alcohol concentration = .10%) or no alcohol. They then read an eroticized sexual scenario and reported on their dissociation and emotional numbing experiences, unprotected sex refusal self-efficacy, and unprotected sex intentions. Results Path analysis revealed that CSA was indirectly associated with increased unprotected sex intentions through increased ASA severity, increased trauma-related symptoms, increased emotional numbing, and decreased unprotected sex refusal self-efficacy. Further, alcohol intoxication was indirectly associated with increased unprotected sex intentions through increased emotional numbing and decreased unprotected sex refusal self-efficacy. Conclusions Emotional numbing, but not dissociation, was associated with unprotected sex intentions and may be one potential target for interventions aimed at reducing HIV/STI-related risk among women with a history of sexual trauma.

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.
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.

Assertive resistance to sexual assault can decrease the likelihood of completed rape and its subsequent aftermath; however, this relationship may be influenced by situational characteristics. This study examined how 2 manipulated variables, level of consensual sex during an encounter and acute alcohol intoxication, along with sexual victimization history, affected women's responses to a hypothetical sexual assault scenario. Female participants were assigned to a drink condition (alcohol/control) and to a consent history condition (low/high). Path analysis found that women who were previously victimized, consumed alcohol, and who were in the high consent condition endorsed greater immobility intentions during the assault; only level of consent predicted likelihood of assertive resistance. Resistance strategies were related to subsequent responding. Results suggest that interventions should seek to decrease negative consequences by empowering women to assertively resist unwanted sexual advances.

We report a rare case of serious voluntary intoxication by laboratory thallium monobromate combined with alcohol intake by a 24-years old man. The diagnosis of thallium intoxication was based on history, nonspecific but typical clinical symptoms including gastrointestinal complaints, painful polyneuropathy, alopecia, and confirmed by the finding of increased thallium concentration in the urine. The treatment, performed at the due time, consisted of decontamination of the stomach by irrigation, administration of active charcoal and Prussian blue, correction of water and mineral dysbalance, symptomatic treatment, and led to complete recovery.
Full Text Available This study is designed to evaluate the effects of a herbal composition of Semen Hoveniae, Radix Puerariae and Fructus Schisandrae (SRF against acute alcoholic intoxication. The animals were treated with SRF extract (SRFE for 14 days, and ethanol was conducted subsequent to the final treatment. The effects of SRFE on righting reflex, inebriety rates, kinetic parameters of blood ethanol and acetaldehyde were determined. In addition; levels of alcohol dehydrogenase (ADH and aldehyde dehydrogenase (ALDH, the activities of cytochrome P450 2E1 (CYP2E1, selected antioxidative enzymes, and the contents of malonaldehyde (MDA were measured. SRFE-pretreated rodents exhibited lower rates of intoxication, longer times to loss of righting reflex, and shortened times to recovery of righting reflex than in controls. The peak concentrations and area under the time-concentration curves were lower in the pretreated animals than in controls, which corresponded to higher levels of ADH and ALDH in both gastrointestines and livers of the SRFE-treated animals. The activities of CYP2E1 were lower in SRFE-pretreated animals, which also exhibited higher activities of some antioxidant enzymes and lower hepatic MDA levels. These findings suggest that the anti-inebriation effects of SRFE may involve inhibition of ethanol absorption, promotion of ethanol metabolism, and enhancing hepatic anti-oxidative functions.

Over a 10-year period (1998-2007) all deaths in Sweden classified by forensic pathologists as fatal drug poisonings (N = 6894) were retrieved from a toxicology database (TOXBASE) belonging to the National Board of Forensic Medicine. The deaths were further classified as suicides N = 2288 (33%), undetermined N = 2260 (33%) and accidental N = 2346 (34%). The average age (± SD) of all victims was 49.1 ± 15.9 years and men 47.4 ± 15.6 years were 5-year younger than women 52.2 ± 15.8 years (p drug users although a single drug (mono-intoxications) was found in 22% of all poisoning deaths (p drugs in blood samples varied from 1 to 12 with a median of 3-4 per case. Mono-intoxication deaths were mostly ethanol-related (N = 976) and the mean and median blood-alcohol concentration (BAC) was 3.06 g/L and 3.10 g/L, respectively. The BAC decreased as the number of additional drugs in blood increased from 2.15 g/L with one drug to 1.25 g/L with 6 or more drugs. The mean (median) concentrations of non-alcohol drugs in mono-intoxication deaths were morphine (N = 93) 0.5mg/L (0.2mg/L), amphetamine (N = 39) 2.0mg/L (1.2mg/L), dextropropoxyphene (N = 33) 3.9 mg/L (2.9 mg/L), dihydro-propiomazine (N = 32) 1.6 mg/L (1.0mg/L) and 7-amino-flunitrazepam (N = 28), 0.4 mg/L (0.3mg/L). Elevated blood morphine in these poisoning deaths mostly reflected abuse of heroin as verified by finding 6-monoacetyl morphine (6-MAM) in the blood samples. When investigating drug poisoning deaths a comprehensive toxicological analysis is essential although the results do not reveal the extent of prior exposure to drugs or the development of pharmacological tolerance. The concentrations of drugs determined in post-mortem blood are one element in the case. The autopsy report, the police investigation, the findings at the scene and eye-witness statements should all be carefully considered when the cause and manner of death are determined.

Full Text Available This presentation reviews data from studies on the encephalon in 27 men ranging in age from 21 to 51 years, showing signs of chronic alcohol intoxication and who died from causes other than skull injury and 14 control subjects. The specimens were fixed in formalin or Karnua liquid, filled with paraffin and then examined, utilizing a variety of histological, histochemical and morphometric techniques. The data refers to the structural changes in the various tissue components of the brain (nervous, glia-cells, arteries, veins, as well as pertinent information concerning the presence of Protozoa in all the sections examined which according to their morphological signs and behavioral reactions indicate that amoeba had been present. The degree of cerebral tissue insemination by these parasites has been demonstrated. The condition of the membranes of these microorganisms, their cytoplasm, nucleus and nucleoli as well as the chromatoid corpuscles has been assessed and recorded. The ability of these microorganisms to split, migrate within the CNS limits, to trigger incitement and dystrophic changes and in the case of death – calcification or exulceration is shown. Further, the issue of species characteristics of amoeba occurring in the patients’ brains is discussed. The hypothesis of a possible link of amebic invasion with the development of alcohol dependence in humans is proposed.

Intoxications involving prescription opioids are a major public health problem in many countries. When taken with opioids, alcohol can enhance the effects of opioids, particularly in the central nervous system. However, data quantifying the impact of alcohol involvement in opioid-related intoxications are limited. Using claims data from the German Pharmacoepidemiological Research Database (GePaRD), we conducted a retrospective cohort study based on users of high-potency opioid (HPO) analgesics during the years 2005-2009. HPO use was classified as extended-release, immediate-release or both. We calculated incidence rates (IRs) for opioid intoxications or related events as well as adjusted IR ratios (aIRR) comparing HPO-treated patients with alcohol-related disorders (ARDs) to those without ARDs overall and within each HPO category. During the study period, 308,268 HPO users were identified with an overall IR of 340.4 per 100,000 person-years [95 % confidence interval (CI) 325.5-355.7]. The risk was highest when patients received concomitant treatment with extended- and immediate-release HPOs (IR 1093.8; 95 % CI 904.6-1310.9). ARDs increased the risk during HPO use by a factor of 1.7 and the highest aIRR was seen when comparing patients simultaneously exposed to extended- and immediate-release HPOs with ARDs to those without ARD also after excluding patients with potential improper/non-medical HPO use. Physicians should be aware of these elevated risks in HPO patients with ARDs. Active patient education by healthcare providers regarding the risk of opioid intoxications or related events due to alcohol in conjunction with HPOs is warranted.

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.

Decoctions of Plectranthus species are traditionally ingested after large meals for treatment of food digestion and alcohol abuse. This study aims at associating the digestion-related ethno-uses of Plectranthus species decoctions to molecular mechanism that might explain them: easing digestion (AChE inhibition) and treating hangover (ADH inhibition) MATERIAL AND METHODS: Decoctions from Plectranthus species were analysed for their alcohol dehydrogenase (ADH) inhibition and acetylcholinesterase (AChE) inhibition, related with alcohol metabolism and intestinal motility, respectively. Identification of the active components was carried out by LC-MS/MS and the docking studies were performed with AChE and the bioactive molecules detected. All decoctions inhibited ADH activity. This inhibition was correlated with their rosmarinic acid (RA) content, which showed an IC 50 value of 19 μg/mL, similar to the reference inhibitor CuCl 2 . The presence of RA also leads to most decoctions showing AChE inhibiting capacity. P. zuluensis decoction with an IC 50 of 80 μg/mL presented also medioresinol, an even better inhibitor of AChE, as indicated by molecular docking studies. Furthermore, all decoctions tested showed no toxicity towards two human cell lines, and a high capacity to quench free radicals (DPPH), which also play a helpful in the digestive process, related with their RA content. All activities presented by the RA-rich Plectranthus decoctions support their use in treating digestion disorders and P. barbatus could explain its use also for alleviating hangover symptoms. Medioresinol, which is present in P. zuluensis, exhibited a significant AChE inhibition and may provide, in the future, a new lead for bioactive compounds. Copyright © 2018 Elsevier B.V.

Full Text Available Bilateral gluteal compartment syndrome is a rare clinical entity that can be complicated by rhabdomyolysis or acute kidney injury (AKI. We report the a case of a 30-year-old woman without any comorbid diseases who was diagnosed with bilateral gluteal compartment syndrome complicated by rhabdomyolysis and dialysis-requiring AKI, which was caused by prolonged immobilization under the influence of alcohol. Although the patient’s renal function recovered fully after 5 sessions of hemodialysis, sciatic neuropathy caused by gluteal compartment syndrome led to permanent foot drop.
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.
[Limitations in medico-legal appraisal of sobriety or alcohol intoxication in drivers and the use of retrospective calculation. Practical comments based on an analysis of the files investigated in the chair of forensic medicine, Medical University of Silesia, Katowice, in the years 2000-2004].
Rygol, Krystian; Kabiesz-Neniczka, Stanisława
In case of a driver who was involved in and survived a traffic accident, the analysis of expired air or blond sampling for alcohol determination is usually done within a shorter or longer time interval after the event. Thus, that the obtained analytical results are to be referred to the time when the examination or sampling was done, whereas the courts are interested in the driver's sobriety of alcohol intoxication at the critical moment, i.e. at the moment of the accident. Knowledge of alcohol toxicology allows for performing some simplified calculations to determine estimated blood alcohol concentration levels similar to those at the critical moment by using the so-called retrospective analysis. The authors performed a statistical analysis of the court files investigated at the Chair of Forensic Medicine, Medical University of Silesia, Katowice, in the years 2000-2004, especially focusing on difficulties encountered in cases of alcohol intoxication in perpetrators of traffic collisions.
Impact of alcohol intoxication and withdrawal syndrome on social phobia and panic disorder in alcoholic inpatients Impacto das fases de intoxicação e de abstinência de álcool sobre a fobia social e o transtorno de pânico em pacientes alcoolistas hospitalizados
Mauro Barbosa Terra
Full Text Available PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval. RESULTS: Only 1 (2.4% patient presented panic disorder throughout life, and 9 (21.9% had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39% alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.OBJETIVO: Estudar o impacto das fases de intoxicação e de abstinência do uso de álcool sobre o curso da fobia social e do transtorno de pânico.

Information on acute intoxications during work in the Netherlands has been gathered from 4 sources during a 1-year period: 1. The registration of occupational accidents of the Directorate-General of Labour, by reviewing reports on accidents involving chemicals; 2. The Netherlands Poison Control Centre of the National Institute for Public Health and Environmental Hygiene, by tracing back consulting physicians; 3. The Dutch Centre for Health Care Information, by searching their data base for hospital admissions with relevant admission diagnoses and 4. A large Occupational Health Service, which for this purpose recorded incident cases in the population under care. During the period of investigation 5 deaths were reported: 1 case of hydrogen cyanide intoxication, 1 case of carbon dioxide intoxication, and 3 cases of hydrogen sulfide intoxication in combination with oxygen deficiency (nearby a liquid manure tank). At least 690 (supposed) acute intoxications during work occurred, which in 84 cases resulted in hospital admission. The total number of hospital admissions for supposed unintentional acute intoxications by chemicals, usually encountered in workplaces, in the Netherlands in 1984 was at least 477. Substances most often involved belonged to the groups of pesticides, lung and/or skin irritant liquids/vapors/gases and asphyxiants. The working branches most often involved were agriculture and market gardening sectors, (chemical) industries, repair and retail trade and some governmental services (police, fire brigade, defense personnel). The results show considerable underreporting in official statistics on acute intoxications during work.

Methyl alcohol poisoning has been mainly reported in community. Two cases of methyl alcohol poisoning occurred in a small-sized subcontracted factory which manufactured smartphone parts in Korea. One young female patient presented with dyspnea and visual disturbance. Another young male patient presented with visual disturbance and myalgia. They treated with sodium bicarbonate infusion and hemodialysis for metabolic acidosis. In addition, he received ethyl alcohol per oral treatment. Her and his urinary methyl alcohol concentration was detected as 7.632 mg/L, 46.8 mg/L, respectively, although they were treated hemodialysis. Results of the working environment measurement showed that the concentration of methyl alcohol (1030.1-2220.5 ppm) in the air exceeded the time weighted average (200 ppm). They were diagnosed with optic neuropathy due to methyl alcohol poisoning and still have visual impairment. Workers who hired as dispatched employees in a small-sized subcontracted factory were exposed to high concentrations of methyl alcohol. The workplace had poor ventilation system. In addition, workers did not wear proper personal protect equipment. Working environment measurement and annual chekups for workers were not performed. They were in a blind spot to occupational safety and health. More attention is needed to protect vulnerable workers' health.

Full Text Available Colchicine is an alkaloid extracted from autumnal Colchicum plant which is used primarily for its anti-inflammatory therapy effect. Acute intoxication with colchicine is uncommon but often severe and results in multiple visceral organ dysfunctions. The intoxication severity and mortality are directly depending on the ingested dose. The treatment is manly symptomatic. However, the development of specific anti-colchicine immunotherapy would offer a new therapeutic perspective. Authors report a case of a young patient that ingested 40 tablets colchicine, which caused a multiple organ failure and with fatal outcome.

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

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.

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.

The evidence on the effect of sleep deprivation on the cognitive and motor skills of physicians in training is sparse and conflicting, and the evidence is nonexistent on surgeons in practice. Work-hour limitations based on these data have contributed to challenges in the quality of surgical education under the apprentice model, and as a result there is an increasing focus on competency-based education. Whereas the effects of alcohol intoxication on psychometric performance are well studied in many professions, the effects on performance in surgery are not well documented. To study the effects of sleep deprivation on the surgical performance of surgeons, we compared simulated the laparoscopic skills of staff gynecologists "under 2 conditions": sleep deprivation and ethanol intoxication. We hypothesized that the performance of unconsciously competent surgeons does not deteriorate postcall as it does under the influence of alcohol. Nine experienced staff gynecologists performed 3 laparoscopic tasks in increasing order of difficulty (cup drop, rope passing, pegboard exchange) on a box trainer while sleep deprived (0.08 mg/mL blood alcohol concentration). Three expert laparoscopic surgeons scored the anonymous clips online using Global Objective Assessment of Laparoscopic Skills criteria: depth perception, bimanual dexterity, and efficiency. Data were analyzed by a mixed-design analysis of variance. There were large differences in mean performance between the tasks. With increasing task difficulty, mean scores became significantly (P sleep-deprived and intoxicated participants were similar for all variables except time. Surprisingly, participants took less time to complete the easy tasks when intoxicated. However, the most difficult task took less time but was performed significantly worse compared with being sleep deprived. Notably, the evaluators did not recognize a lack of competence for the easier tasks when intoxicated; incompetence surfaced only in the most
Conclusion: DGs appear to normalize heavy drinking and the culture of intoxication on this campus. Measures to monitor alcohol sales outlets around campuses and interventions that target students' leisure spaces should be developed.
Intoxicação alcoólica em crianças e adolescentes: dados de um centro de assistência toxicológica Intoxicación alcohólica en niños y adolescentes: datos de un centro de asistencia toxicológica Alcoholic intoxication in children and adolescents: information from an intoxication control center

one of the biggest social and health issues of our time. This study aims to characterize the toxicological occurrences among children and teenagers aged to 18 years-old, hospitalized because of alcoholic intoxication and notified in an Intoxication Control from 2003 to 2007. The present work is a retrospective study, with qualitative analysis of the data. 338 occurrences were found. It was observed that alcohol abuse occurred mainly among the masculine sex, being weekends, the night time, and intense use of most often occurrence. Violent acts associated with alcoholic intoxication have increased 12 times the chances of hospitalization and it has been observed a significant relation between the chronic use and the intensification of clinical seriousness. We suggest studies on the subject and the implementation of preventive politics and strategies, having teenagers and children as the main audience.

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)

Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. 70 % of people under risk of having alcohol problems go undetected in medical practice, a fact that underlines the need for specific screening measures allowing early detection leading to timely treatment. This article presents evidence gathered by alcohol abuse and dependence screening as well as by risk factor identification and screening. It also presents evidence concerning withdrawal symptoms, delirium tremens and Wernicke's encephalopathy in order to promote early detection and timely treatment. Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. Evidence was found and recommendations were made for the pertinent screening and search of risk factors, in order to perform a diagnosis and carry out a timely management of alcohol abuse, dependence and ensuing complications: withdrawal syndrome, delirium tremens and Wernicke's encephalopathy.

Familial risk and protective factors in alcohol intoxicated adolescents: psychometric evaluation of the family domain of the Communities That Care Youth Survey (CTC) and a new short version of the Childhood Trauma Questionnaire (CTQ).
Kuttler, Heidi; Schwendemann, Hanna; Bitzer, Eva Maria
Alcohol intoxicated adolescents (AIA) in emergency department are an important target group for prevention and valid information on their familial risk and protective factors (RPF) is crucial for implementing customized family-based counseling in hospitals. We therefore, examined the psychometric characteristics of scales which assess familial RPF. We used seven family scales from the Communities That Care Youth Survey Instrument (CTC-F7); four assess risk factors: family conflicts, poor family management, parental attitudes favorable towards drug use/antisocial behavior; three assess protective factors: family attachment, opportunities and rewards for prosocial involvement. To assess physical and emotional abuse and emotional neglect, we created a new scale composed of six items from the Childhood Trauma Questionnaire (CTQ-6). We tested these eight scales on 342 AIA aged 13-17. Based on the classical test theory we calculated descriptive item and scale statistics and internal consistency. We assessed construct validity by confirmatory factor analysis with Maximum Likelihood (ML) estimation in a sample with imputed missing values (EM-Algorithm). To check robustness, we repeated the analyses with complete cases, with multiple imputed data, and with methods suitable for categorical data. We used SPSS 21, AMOS 21 and R (randomForrest and lavaan package). Three of seven CTC-F scales showed poor psychometric properties in the descriptive analysis. A ML-confirmatory model with five latent factors fitted the remaining CTC-F scales best (CTC-F5). The latent structure of the CTQ-6 is characterized by three first-order factors (physical abuse, emotional abuse, emotional neglect) and one second-order factor. The global goodness-of-fit indices for the CTC-F5 and the CTQ-6 demonstrated acceptable fit (for both models: TLI and CFI>0.97, RMSEA0.7). The final CTC-F5 and the newly developed CTQ-6 demonstrate acceptable to good psychometric properties for the AIA sample. The CTC-F5

Drinking to intoxication is a modifiable risk factor for various health, social, and legal problems. The objective was to estimate the relative risk of intoxication by type of drinking location. Participants were 1614 university students (mean age 19.0 years) in residential halls who completed a web survey (67% response). Respondents reported their drinking for each day of the preceding week, in residential halls, pubs/bars/nightclubs, student flats/houses, and 'other' locations. An estimated blood alcohol concentration (EBAC) was computed and intoxication was defined as EBAC>0.08%. Pubs/bars/nightclubs accounted for 51% of all alcohol consumed, followed by residential halls (34%), student flats/houses (9%), and other locations (6%). Episodes resulting in intoxication comprised 61% of all drinking episodes in pubs/bars/nightclubs, 55% in student flats/houses, 53% in residential halls, and 37% in other locations. Multi-level analyses revealed positive associations between the first three location types (relative to 'other') and intoxication among women. Drinking in pubs/bars/nightclubs was associated with intoxication among men. Other significant predictors included hazardous drinking in the respondent's residential hall, pre-university drinking, and first-year status. Student intoxication is commonplace in licensed premises and residential halls. These environments are amenable to interventions to reduce the incidence of intoxication.

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.

Manganese (Mn), upon absorption, is primarily sequestered in tissue and intracellular compartments. For this reason, blood Mn concentration does not always accurately reflect Mn concentration in the targeted tissue, particularly in the brain. The discrepancy between Mn concentrations in tissue or intracellular components means that blood Mn is a poor biomarker of Mn exposure or toxicity under many conditions and that other biomarkers must be established. For group comparisons of active workers, blood Mn has some utility for distinguishing exposed from unexposed subjects, although the large variability in mean values renders it insensitive for discriminating one individual from the rest of the study population. Mn exposure is known to alter iron (Fe) homeostasis. The Mn/Fe ratio (MIR) in plasma or erythrocytes reflects not only steady-state concentrations of Mn or Fe in tested individuals, but also a biological response (altered Fe homeostasis) to Mn exposure. Recent human studies support the potential value for using MIR to distinguish individuals with Mn exposure. Additionally, magnetic resonance imaging (MRI), in combination with noninvasive assessment of γ-aminobutyric acid (GABA) by magnetic resonance spectroscopy (MRS), provides convincing evidence of Mn exposure, even without clinical symptoms of Mn intoxication. For subjects with long-term, low-dose Mn exposure or for those exposed in the past but not the present, neither blood Mn nor MRI provides a confident distinction for Mn exposure or intoxication. While plasma or erythrocyte MIR is more likely a sensitive measure, the cut-off values for MIR among the general population need to be further tested and established. Considering the large accumulation of Mn in bone, developing an X-ray fluorescence spectroscopy or neutron-based spectroscopy method may create yet another novel non-invasive tool for assessing Mn exposure and toxicity.

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.

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.

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

To examine attendance at alcohol-service and alcohol-free parties among college students, and to compare alcohol consumption on nights of these parties. A random sample of 556 students (38.6% male) completed a web survey that measured past-semester alcohol use, alcohol-service party attendance, alcohol-free party attendance, and alcohol consumed on the nights of recent parties. Participants were twice as likely to attend alcohol-service parties as they were to attend alcohol-free parties (90% vs. 44%). First-year students and Black students were more likely than other students to attend alcohol-free parties. Alcohol use was higher in students who attended alcohol-service parties but there were no differences in levels of alcohol use between students who attended alcohol-free parties and those who did not. Pre-gaming was more prevalent, but the number of drinks and intoxication were lower on nights of alcohol-free parties than on nights of alcohol-service parties. The lack of association between attendance at alcohol-free parties and alcohol use indicates both heavy and light drinkers attend these parties. The lower drinking and intoxication on alcohol-free party nights suggests alcohol-free programming should be investigated to determine if it may reduce alcohol use on college campuses.

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.

We report a case of a 37-year-old woman with non-insulin-dependent diabetes on sitagliptin, an alcohol abuser who was brought unresponsive to the emergency department of our hospital. On arrival, the patient was intubated and mechanically ventilated due to a low Glasgow Coma score of 3/15. Initial laboratory testing identified profound high anion gap metabolic acidosis. Owing to the dubious circumstances and the depth of acidosis, methanol and ethylene glycol intoxication was suspected. Further evaluation revealed a significantly increased serum osmolal gap. Pending volatile compound screen, fomepizole was started and urgent haemodialysis undertaken. Subsequent brain MRI identified changes in putamen of bilateral basal ganglia, suggestive of methanol intoxication. The patient was later found to have an initial methanol level of 237 mg/dL. She was successfully extubated on day 2 of hospitalisation, with residual cognitive and visual deficits. 2016 BMJ Publishing Group Ltd.

Heavy alcohol use is widespread among college students, particularly in those social situations where the risk of rape rises. Few studies have provided information on rapes of college women that occur when they are intoxicated. The purpose of the present study was to present prevalence data for rape under the condition of intoxication when the victim is unable to consent and to identify college and individual-level risk factors associated with that condition. The study utilizes data from 119 schools participating in three Harvard School of Public Health College Alcohol Study surveys. The analytic sample of randomly selected students includes 8,567 women in the 1997 survey, 8,425 in the 1999 survey, and 6,988 in the 2001 survey. Roughly one in 20 (4.7%) women reported being raped. Nearly three quarters (72%) of the victims experienced rape while intoxicated. Women who were under 21, were white, resided in sorority houses, used illicit drugs, drank heavily in high school and attended colleges with high rates of heavy episodic drinking were at higher risk of rape while intoxicated. The high proportion of rapes found to occur when women were intoxicated indicates the need for alcohol prevention programs on campuses that address sexual assault, both to educate men about what constitutes rape and to advise women of risky situations. The findings that some campus environments are associated with higher levels of both drinking and rape will help target rape prevention programs at colleges.

Current trauma guidelines dictate that the cervical spine should not be cleared in intoxicated patients, resulting in prolonged immobilization or additional imaging. Modern computed tomography (CT) technology may obviate this and allow for immediate clearance. To analyze cervical spine clearance practices and the utility of CT scans of the cervical spine in intoxicated patients with blunt trauma. We performed a prospective observational study of 1668 patients with blunt trauma aged 18 years and older who underwent cervical spine CT scans from March 2014 to March 2015 at an American College of Surgeons-verified Level I trauma center. Intoxication was determined by serum alcohol levels and urine drug screens. Physical examination and CT scan findings were evaluated for cervical spine injuries (CSI) and the incidence of missed injuries. Clinically relevant CSIs requiring cervical stabilization. The hypotheses formed prior to data collection were that cervical CT scans are sensitive and specific enough to diagnose CSIs that require stabilization and that normal CT scans are sufficient to clear CSIs in intoxicated patients. Of 1668 patients, 1103 (66.1%) were male, with a mean (SD) age of 49 (20) years and a mean (SD) Injury Severity Score of 10 (9). Vehicular (734 [44.0%]) and falls (579 [34.7%]) were the most common mechanisms for hospitalization. Intoxication was identified in 632 of 1429 of patients tested (44.2%; 425 [29.7%] by serum alcohol levels and 350 [24.5%] by urine drug screens). Half (316 [50.0%]) were admitted with cervical spine immobilization, and 38 (12%) of these were solely owing to the presence of intoxication. There were 65 abnormal CT scans (10.3%) in the intoxicated group. Among 567 normal CT scans, 4 (0.7%) had central cord syndrome found on initial physical examination, and 1 (0.2%) had a symptomatic unstable ligament injury that was misread as normal on CT scan but was abnormal on magnetic resonance imaging. The 316 patients kept in a

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

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.

Full Text Available In “Afterword: Intoxication as a Zone of Exception,” Joseph M. Gabriel turns our eye to what lies past intoxication: getting trashed or wasted. Even as he concedes that intoxication at its extreme marks the impossible boundary beyond the articles collected in this issue, he refuses to throw out the excess with the trash of its own terminology. Taken in the context of Michel Foucault and Giorgio Agamben’s theories, extreme intoxication represents a user’s resistance to the ways that enlightenment rationality comes up against and frames individual agency.

Accidental or intentional ingestion of substances containing methanol and ethylene glycol can result in death, and some survivors are left with blindness, renal dysfunction, and chronic brain injury. However, even in large ingestions, a favorable outcome is possible if the patient arrives at the hospital early enough and the poisoning is identified and appropriately treated in a timely manner. This review covers the common circumstances of exposure, the involved toxic mechanisms, and the clinical manifestations, laboratory findings, and treatment of methanol and ethylene glycol intoxication.

Full Text Available For a long time, alcohol was thought to exert a general depressant effect on the central nervous system (CNS. However, currently the consensus is that specific regions of the brain are selectively vulnerable to the acute effects of alcohol. An alcohol-induced blackout is the classic example; the subject is temporarily unable to form new long-term memories while relatively maintaining other skills such as talking or even driving. A recent study showed that alcohol can cause retrograde memory impairment, that is, blackouts due to retrieval impairments as well as those due to deficits in encoding. Alcoholic blackouts may be complete (en bloc or partial (fragmentary depending on severity of memory impairment. In fragmentary blackouts, cueing often aids recall. Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol on learning and memory may result from alteration of the hippocampus and related structures on a cellular level. A rapid increase in blood alcohol concentration (BAC is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts, implying that genetic factors play a role in determining CNS vulnerability to the effects of alcohol. This factor may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual‟s alcohol expectancy; one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Extensive research on memory and learning as well as findings related to the acute effects of alcohol on the brain may elucidate the mechanisms and impact associated with the alcohol- induced blackout.

Full Text Available 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.

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.

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

Full Text Available According to alcohol-myopia theory, acute alcohol consumption leads people to disproportionally focus on the salient rather than the peripheral aspects of a situation. We summarize various studies exploring how myopic processes resulting from acute alcohol intake affect goal commitment. After consuming alcohol student participants felt strongly committed to an important personal goal even though they had low expectations of successfully attaining the goal. However, once intoxicated participants were sober again (i.e., not myopic anymore they failed to act on their goal commitment. In line with alcohol-myopia theory, strong goal commitment as a result of alcohol intake was mediated by intoxicated (vs. sober participants disproportionally focusing on the desirability rather than the feasibility of their goal. Further supporting alcohol-myopia theory, when the low feasibility of attaining a particular goal was experimentally made salient (either explicitly or implicitly by subliminal priming, intoxicated participants felt less committed than those who consumed a placebo. We discuss these effects of acute alcohol intake in the context of research on the effects of chronic alcohol consumption on goal commitment.

Full Text Available Seventy-eight patients with moderate, severe, and fatal (n = 12 acute intoxication with barbiturates, as evidenced by the measurements of their blood concentrations were examined. Cardiointervalography was made during follow-up ECG in all the patients in order to determine the tension index (TI, a cumulative measure of the tone of the autonomic nervous system. Comparison of clinical, laboratory, and cardiointervalographic data showed that sympathicotonia (TI, 90—160 conventional units was predominant in moderate intoxication with barbiturates (their concentration was 16.14±3.2 ^g/ml, there was hypersympathicotonia (TI, more than 160 conventional units in severe intoxication (the concentration of barbiturates, 30.56±7.6 ^g/ml; the increased tone of the parasympathetic portion of the autonomic nervous system — vagotonia (TI, less than 30 conventional units in fatal intoxication (the concentration of barbiturates, 37.3±6.6 ^g/ml. Moreover, TI decreased with the age of patients and increased with combined intoxication with barbiturates and alcohol (its blood concentration was more than 1 g/l.

Consumption of alcohol mixed with caffeinated energy drinks is becoming popular, and the number of pre-mixed caffeinated alcohol products on the worldwide market is increasing. There is public health concern and even occasional legal restriction relating to these drinks, due to associations with increased intoxication and harms. The precise nature and degree of the pharmacological relationship between caffeine and alcohol is not yet elucidated, but it is proposed that caffeine attenuates the sedative effects of alcohol intoxication while leaving motor and cognitive impairment unaffected. This creates a potentially precarious scenario for users who may underestimate their level of intoxication and impairment. While legislation in some countries has restricted production or marketing of pre-mixed products, many individuals mix their own energy drink-alcohol 'cocktails'. Wider dissemination of the risks might help balance marketing strategies that over-emphasize putative positive effects.
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.
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.

To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. An adult castrated male Australian cattle dog presented to an emergency clinic for an acute onset of ataxia and disorientation after roaming a construction site unsupervised. He tested positive for ethylene glycol using a point-of-care test kit. Treatment for ethylene glycol intoxication included intermittent intravenous boluses of 20% ethanol and hemodialysis. Predialysis and postdialysis blood samples were submitted to the toxicology lab to assess for both ethylene and propylene glycol. The patient tested negative for ethylene glycol and positive for propylene glycol at 1100 mg/dL predialysis and 23 mg/dL postdialysis. The dog made a full recovery. To the authors' knowledge, this is the first report of documented propylene glycol intoxication in a dog, as well as the first report to describe hemodialysis as treatment for propylene glycol intoxication in a dog. © Veterinary Emergency and Critical Care Society 2011.

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

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.

In a longitudinal study of 1230 people aged 13-18 years from the Greater Oslo Area, the past-year prevalence of anxiolytic or hypnotic use was 10%, which is higher than previously reported. The majority gave therapeutic reasons as a motive for using these drugs. However, most of the use was unprescribed. The parents, and especially the mother, were the most important suppliers. A minority gave intoxication as a motive for using these drugs. In this group, the suppliers were mainly peers and the illegal market. Neither the unprescribed nor the prescribed therapeutic use show any association with use of drugs such as alcohol and cannabis. There is, however, a strong association between the unprescribed use of benzodiazepines by young people and by their parents. This suggests a pattern of learning and role modelling, which must be regarded as problematic for public health policy. Those who use the drugs to become intoxicated have particularly poor mental health, and they use many other drugs as well. This group probably runs a special risk of developing more serious drug abuse.

Full Text Available Aim: The aim of this study was to evaluate the suicide and intoxication cases between April 2011 and April 2013. Methods: We retrospectively analyzed hospital records of patients who were admitted to our intensive care unit due to suicide and intoxication. The age, sex, intoxication causes, laboratory analyses, treatment refusal rates, and the prognosis were evaluated. Results: A total of 308 patients (105 males, 203 females were admitted to the intensive care unit. The mean age of the patients was 27.45±10.26 years (males: 28.70±9.86 years, females: 26.80±10.43 years. There were only 4 patients over 65 years of age. 275 patients had drug intoxication (antidepressant drug, pain killer, antibiotic, etc. and 33 patients had other causes of intoxication. When analyzing the prognosis; a total of 234 patients were discharged after initial treatment and 57 patients were discharged due to treatment refusal. 15 patients were referred for inpatient psychiatric treatment, 1 patient to the Alcohol and Drug Addiction Treatment Center (AMATEM and 1 patient was referred to İstanbul University Medical Faculty due to acute hepatic failure. Conclusion: The patients admitted to our intensive care unit due to suicide and intoxications were mainly females (65.9% and individuals of young age (median age: 27.45 years. Female patients had used antidepressants for suicide attempts and males had used antiflu-acetaminophen combinations. No mortality was observed. (The Medical Bulletin of Haseki 2014; 52:153-7

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

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.

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

Excess consumption of alcohol leads to impaired cognition and decision making; hence, alcohol-containing products and advertising contain warning messages about the adverse effects of excess drinking. However, there is a need to understand how alcohol influences the processing of advisory messages. The current study used a computerised gambling simulation and investigated whether intoxication would affect the use of a decision aid. Using a double-blind repeated measures design, 16 adult males (aged 18-29) completed the Alcohol Use Disorders Identification Test and the South Oaks Gambling Screen and played a computer blackjack program on two separate occasions, under differing doses of alcohol. On certain conditions, the computerised decision aid gave advice to participants as to whether the odds were in their favour. Participants were found to take longer to respond to the decision aid under higher risk conditions when they were losing. Alcohol intoxication may lead to problems evaluating information pertaining to risk, and this has implications for the use of other decision aids designed to assist intoxicated individuals. The problems processing warning information were consistent with alcohol induced 'myopia' where intoxicated individuals had problems processing less salient cues.

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.

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.
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 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 Despite the intoxication of many eyewitnesses at crime scenes, only four published studies to date have investigated the effects of alcohol intoxication on eyewitness identification performance. While one found intoxication significantly increased false identification rates from target absent showups, three found no such effect using the more traditional lineup procedure. The present study sought to further explore the effects of alcohol intoxication on identification performance and examine whether accurate decisions from intoxicated witnesses could be postdicted by confidence and response times. One hundred and twenty participants engaged in a study examining the effects of intoxication (control, placebo, and mild intoxication and target presence on identification performance. Participants viewed a simultaneous lineup one week after watching a mock crime video of a man attempting to steal cars. Ethanol intoxication (0.6 ml/kg was found to make no significant difference to identification accuracy and such identifications from intoxicated individuals were made no less confidently or slowly than those from sober witnesses. These results are discussed with respect to the previous research examining intoxicated witness identification accuracy and the misconceptions the criminal justice system holds about the accuracy of such witnesses.

Topographic maps of brain electrical activity from scalp EEG electrodes were obtained from healthy adult female volunteers using a Brain Electrical Activity Mapping (BEAM) system. Each woman received both ethanol (0.7 g/kg, p.o.) and placebo in a counterbalanced order under double-blind conditions at an interval of 1-6 days. Subjective reports of intoxication were obtained continuously via an instrumental joystick device. Subjects reported when they detected ethanol and qualitatively pleasant (i.e., euphoric) or unpleasant (i.e., dysphoric) effects. All subjects reliably discriminated ethanol from placebo. Pronounced increases in EEG alpha activity occurred during ethanol-induced intoxication in all subjects. Analysis of topographic maps revealed that the distribution of high-amplitude, fast-frequency EEG alpha activity extended further frontally to the central sulcus and temporally during ethanol intoxication than during control sessions or after placebo administration. Area analysis and significant probability mapping techniques were used to quantify the increased alpha activity and to monitor changes during the process of intoxication in each individual. One woman, with a positive family history of alcoholism, experienced only a mild degree of ethanol intoxication. This behavioral response was accompanied by a slight decrease or no change in both slow- and fast-frequency alpha activity. This finding in a single subject provides additional evidence that a possible genetic predisposition for ethanol-related effects on behavior may be reflected in measures of brain electrical activity. Overall, these data also suggest that ethanol induces rapid and widespread increases in EEG alpha activity which may be associated with the reinforcing properties of ethanol.

A structural equation model examined sexual enhancement alcohol expectancies, heavy episodic drinking (HED), and risky sexual behavior as correlates of alcohol-involved rape in a sample of 353 college women. Prevalence of alcohol-involved rape was 15.6%. Sexual enhancement alcohol expectancies were indirectly associated with alcohol-involved rape via increased levels of HED, greater likelihood of sex while intoxicated, and number of sex partners. All forms of risky behavior were associated with alcohol-involved rape although HED had the strongest relationship. Findings suggest continued focus on women's positive alcohol expectancies and HED as risk factors for alcohol-involved rape. Implications for intervention will be discussed.

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.

Background 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. Methods 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. Results 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. Conclusions 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. PMID:27875802

Breathalysing and blood analysis is the basic instrument of measuring the level of intoxication. Prior to collecting a blood sample, an individual suspected of being under the influence of alcohol is examined by a physician, who fills out the "protocol of obtaining a blood sample". This work aims at evaluating the applicability of the described examination in measuring the level of intoxication. In order to do so, our team analyzed 352 "protocols of obtaining blood sample" referred to the Forensic Laboratory KWP in Bydgoszcz, Poland, and compared them with the results of blood analysis. The results of the above analysis point to the fact that the elements of medical examination constituting "the protocol of obtaining a blood sample" are of a minor usefulness in determining the degree of intoxication with ethyl alcohol. The smell from the mouth and the conclusions formulated the examining physician prove to be the most useful. The summary usage of deviations from the norm does not seem to increase the usefulness of methods used within "the protocol of obtaining a blood sample" in evaluating the degree of intoxication.
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.

Numerous investigations indicate a close link between violent behavior, homicide (murder) and alcohol intoxication. With increased frequency of drinking and the chronic consummation of alcohol, the risk of the fatal outcome or homicide and victimization caused by violence is more likely to occur. Studies conducted on convicted murderers suggested that about half of them were under the heavy influence of alcohol at the time of perpetration of murder. The sample in this survey consisted of 177 male offenders which committed criminal act of murder in Croatia from the year of 1990 until 2007 (capital murder and attempted murder). All were assigned for the forensic psychiatric evaluation by the Criminal Justice System (Court of Law) at the Department of Forensic Psychiatry, Neuropsychiatric Hospital, Popovaca, Croatia. For the purpose of this work the sample is divided in two groups of subjects: 1) offenders which were intoxicated at the time of murder and committed offence on intoxicated victim 2) offenders who were sober and committed offence on sober victims. Groups are compared according to the variables of crime and history of alcohol abuse. On the basis of obtained results we can conclude that there are significant differences in relation to the variables and modalities of criminal offence between two groups of offenders and victims. We could conclude that alcohol intoxication in offenders and victims at the time of murder could strongly affect the modalities of murder.

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.

Full Text Available Objective: To describe three patients with occupational blindness from chronic methanol intoxication. Case presentation: Three patients who worked in the same industry of methylated spirit manufacture for more than 1 year developed bilateral visual loss from inhaled methanol intoxication. Ophthalmological, neurological examinations and blood methanol levels were undertaken. Two male and one female patients developed a sudden onset of bilateral blindness. Blood and urine methanol levels obtained from the male patients at 48 and 72 hours after their cessation to methanol exposure were negative. Those from the female patient at 9 hours after their cessation to methanol exposure were 73.78 mg/dl. Their final visual acuity was not improved after the treatment. Conclusion: Chronic methanol intoxication from inhalation is likely to produce ocular problems with mild systemic toxicity with severe ocular problems which eventually result in permanent blindness. The risk assessment of occupational health and safety should be seriously taken into account to avoid harmful effect of hazards in the workplace.

In Colombia (South America) during recent decades the administration of scopolamine, extracted from plants belonging to the Datura or Brugmansia genus, has become an important neurologic and toxicologic phenomenon. These extracts have been popularly known as "Burundanga." Chemical characteristics and clinical features of scopolamine intoxication are described. Anterograde amnesia and submissive behavior found in patients intoxicated with scopolamine are analyzed. Burundanga intoxication is related to other toxic phenomena found in different countries and similitudes with transient global amnesia are emphasized.

Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children's drinking behavior in mid-adolescence are mediated by the children's alcohol expectancies in early adolescence. A sample of 148 initially 9-11 year old boys and their parents from a high-risk population and a contrast group of community families completed measures of drinking behavior and alcohol expectancies over a 6-year interval. We analyzed data from middle childhood (M age = 10.4 years), early adolescence (M age = 13.5 years), and mid-adolescence (M age = 16.5 years). The sample was restricted only to adolescents who had begun to drink by mid-adolescence. Results from zero-inflated Poisson regression analyses showed that 1) maternal drinking during their children's middle childhood predicted number of drinking days in middle adolescence; 2) negative and positive alcohol expectancies in early adolescence predicted odds of any intoxication in middle adolescence; and 3) paternal alcoholism during their children's middle childhood and adolescents' alcohol expectancies in early adolescence predicted frequency of intoxication in middle adolescence. Contrary to predictions, child alcohol expectancies did not mediate the effects of parental alcohol involvement in this high-risk sample. Different aspects of parental alcohol involvement, along with early adolescent alcohol expectancies, independently predicted adolescent drinking behavior in middle adolescence. Alternative pathways for the influence of maternal and paternal alcohol involvement and implications for expectancy models of adolescent drinking behavior were discussed.

Whilst energy drinks improve performance and feelings of alertness, recent articles suggest that energy drink consumption combined with alcohol may reduce perception of alcohol intoxication, or lead to increased alcohol or drug use. This review discusses the available scientific evidence on the effects of mixing energy drinks with alcohol. A literature search was performed using the keywords "energy drink and Red Bull(®)" and consulting Medline/Pubmed, PsycINFO, and Embase. There is little evidence that energy drinks antagonize the behavioral effects of alcohol, and there is no consistent evidence that energy drinks alter the perceived level of intoxication of people who mix energy drinks with alcohol. No clinically relevant cardiovascular or other adverse effects have been reported for healthy subjects combining energy drinks with alcohol, although there are no long-term investigations currently available. Finally, whilst several surveys have shown associations, there is no direct evidence that coadministration of energy drinks increases alcohol consumption, or initiates drug and alcohol dependence or abuse. Although some reports suggest that energy drinks lead to reduced awareness of intoxication and increased alcohol consumption, a review of the available literature shows that these views are not supported by direct or reliable scientific evidence. A personality with higher levels of risk-taking behavior may be the primary reason for increased alcohol and drug abuse per se. The coconsumption of energy drinks being one of the many expressions of that type of lifestyle and personality.

This article presents the results of a study of clinical features of the development and course of alcohol dependence in patients with posttraumatic stress disorder (PTSD) in comparison with alcohol-dependent patients without PTSD. The highly progressive course, continuous alcohol consumption, high alcohol tolerance, rapidly emerged altered forms of alcohol intoxication, alcohol amnesias, alcohol withdrawal with the prevalence of psychopathological component, and more pronounced social and somatic consequences of alcohol abuse were characteristic of the PTSD group. At the same time, the alcohol-dependent patients with PTSD had the best outcome to the end of 12-month treatment with intramuscular injections of vivitrol.

Alcohol sales in Stockholm County decreased by 18 per cent from 1976 to 1981. The socioeconomic status of inpatients treated for alcohol psychosis, alcoholism, alcohol intoxication, liver cirrhosis, and pancreatitis was studied by linking data from the National Housing and Population Censuses...... in 1975 and 1980 with the inpatient care registers for 1976 and 1981. In both years, all rates were highest for people outside the labor market and lowest among white collar employees. The employment rate for those aged 25-44 years and treated in 1981 for alcohol psychosis, alcoholism, and alcohol...... intoxication--already low in 1975--had drifted further downward by 1980. Total rates of inpatient treatment for alcohol-related diagnoses generally declined but the gap between blue collar workers and white collar workers widened.

Datura stramonium is a toxic plant member of the Solanaceae family. Its consumption may result in severe anticholinergic toxicity. We report the intoxication of 5- and 4-year-old brothers with Datura stramonium, which presented in two different manners. The first child presented agitation, hallucination and mydriasis that improved rapidly with benzodiazepine medication. The second presented comatose, mydriasis and Babinski signs. Gastric lavage and activated charcoal administration were performed. The child was intubated and mechanically ventilated until consciousness improvement. Datura stramonium poisoning may be considered by physicians in case of acute onset of decreased consciousness or behaviour trouble associated with anticholinergic signs and symptoms. © 2014 Japan Pediatric Society.

To study whether participation in organized sports during adolescence predicts increased smoking of tobacco, alcohol intoxication and cannabis use from late adolescence to adulthood when controlling for potential confounders. Moreover, to study whether such increased drug use varies according to type of sport (team versus individual), main skills needed (endurance, strength or technical) and level of competition. Survey of national sample of Norwegian high school students (aged 13-19 years) in 1992 (T1) followed-up in 1994 (T2), 1999 (T3) and 2006 (T4) (n = 3251). Outcome measures included smoking of tobacco and 12-month prevalences of alcohol intoxication and cannabis use, respectively. Confounders included pubertal timing, friends' drug use, perceived social acceptance, grades and parental socio-economic status. Latent growth curve analyses showed that initial level of participation in organized sports predicted growth in alcohol intoxication. Those involved initially in team sports had greater growth in alcohol intoxication, but lower growth in tobacco use and cannabis use, during the adolescent and early adult years compared to those involved in technical or strength sports. Practising endurance sports, as opposed to technical or strength sports, predicted reduced growth in alcohol intoxication and tobacco use. Sports participation in adolescence, and participation in team sports in particular, may increase the growth in alcohol intoxication during late adolescent and early adult years, whereas participation in team sports and endurance sports may reduce later increase in tobacco and cannabis use.

Yam bean is a common food in southern Taiwan. However, its seeds are rarely consumed. We describe five patients of yam bean seed poisoning in Taiwan, one of them life-threatening. The five patients presented with perioral numbness, nausea and vomiting after eating a same soup made from yam bean seeds. One of them, a 54-year-old woman, had difficulty breathing and lost consciousness. Physical examination showed dilated pupils and coma with no focal neurological signs. The initial blood pressure was normal. Laboratory data showed a severe anion gap metabolic acidosis, with a serum lactate level of 185 mg/dL. An initial diagnosis of cyanide intoxication was considered and she was given sodium nitrite and sodium thiosulfate i.v. Hypotension ensued shortly afterwards and pulmonary artery catheterization showed a decreased cardiac index. Aggressive fluid and inotropic therapy were given and the patient eventually recovered. The other four patients suffered only minor gastrointestinal and neurological symptoms and received supportive treatment. Cyanide levels were negative in all five patients. Yam bean seed poisoning can cause acute metabolic acidosis and altered mental status, which could be confused with acute cyanide intoxication from a cyanogenic glycoside-containing plant. To our knowledge, this is the first outbreak of yam bean seed poisoning reported in the English published work.

We report a case of a 66-year-old patient with paraquat intoxication resulting in the requirement for hemoperfusion, hemodialysis, and plasma exchange. His initial serum paraquat level was 0.24 µg/mL (0.0-0.1 µg/mL). Activated charcoal (50 g) was administered orally, and high-dose N-acetylcysteine (150 mg/kg) was administered intravenously. In addition, immediate 4 h hemoperfusion was also performed for three consecutive days after admission. Hemodialysis was started on the 4th day after admission because of uremia. On the 9th day after admission, laboratory findings demonstrated hemolytic uremic syndrome (HUS): microangiopathic hemolytic anemia (MAHA), thrombocytopenia, elevated reticulocyte count, and lactate dehydrogenase (LDH). Plasma exchange was performed three times consecutively. Anemia and thrombocytopenia were improved, and LDH was normalized after plasma exchange. Urine output increased to 2240 mL/day on the 18th day after admission, and hemodialysis was discontinued. He is currently being observed at our follow-up clinic without renal impairment or pulmonary dysfunction for 1.5 years since discharge. We should suspect paraquat-associated HUS when thrombocytopenia and anemia are maintained for a long time after paraquat intoxication. © 2013 Wiley Periodicals, Inc.

To estimate the association between implementation of a community-based multi-component intervention (Drink Less Enjoy More) and sales of alcohol to pseudo-intoxicated patrons and nightlife patron awareness of associated legislation. Cross-sectional pre-intervention and follow-up measurements including alcohol test purchases (using pseudo-intoxicated patrons) in licensed premises (stratified random sample; 2013, 2015) and a survey with nightlife patrons (convenience sample; 2014, 2015). One UK municipality with a large night-time economy. Licensed premises (pre=73; follow-up=100); nightlife patrons (pre=214; follow-up=202). The Drink Less Enjoy More intervention included three interacting components: community mobilisation and awareness raising; responsible bar server training; and active law enforcement of existing legislation prohibiting sales of alcohol to, and purchasing of alcohol for, a person who appears to be alcohol intoxicated: 'intoxicated', herein for economy. The primary outcomes were alcohol service refusal to pseudo-intoxicated patrons and nightlife patron knowledge of alcohol legislation (illegal to sell alcohol to, and purchase alcohol for, intoxicated people), adjusted for potential confounders including characteristics of the area, venue, test purchase, and nightlife patron. Pre-intervention, 16.4% of alcohol sales were refused, compared with 74.0% at follow-up (plegislation was higher at follow-up (sales: pre, 44.5%; follow-up, 66.0%; plegislation was higher at follow-up (sales: AOR 2.7, plegislation was also associated with participant age (purchasing) and expectations of intoxication (sales). A community-based multi-component intervention concerning alcohol sales legislation in the UK was associated with a reduction in sales of alcohol to pseudo-intoxicated patrons in on-licensed premises in a UK nightlife setting and an improvement in nightlife patron awareness of associated legislation.

Most of the cycling accidents that occur in Finland do not end up in the official traffic accident statistics. Thus, there is minimal information on these accidents and their consequences, particularly in cases in which alcohol was involved. The focus of the present study is on cycling accidents and injuries involving alcohol in particular. Data on patients visiting the emergency department at North Kymi Hospital because of a cycling accident was prospectively collected for two years, from June 1, 2004 to May 31, 2006. Blood alcohol concentration (BAC) was measured on admission with a breath analyser. The severity of the cycling injuries was classified according to the Abbreviated Injury Scale (AIS). A total of 217 cycling accidents occurred. One third of the injured cyclists were involved with alcohol at the time of visiting the hospital. Of these, 85% were males. A blood alcohol concentration of ≥ 1.2 g/L was measured in nearly 90% of all alcohol-related cases. A positive BAC result was more common among males than females (p < 0.001), and head injuries were more common among cyclists where alcohol was involved (AI) (60%) than among sober cyclists (29%) (p < 0.001). Two thirds (64%) of the cyclists with AI were not wearing a bicycle helmet. The figure for serious injuries (MAIS ≥ 3) was similar in both groups. Intoxication with an alcohol level of more than 1.5 g/L and the age of 15 to 24 years were found to be risk factors for head injuries. The mean cost of treatment was higher among sober cyclists than among cyclists with AI (€2143 vs. €1629), whereas in respect of the cost of work absence, the situation was the opposite (€1348 vs. €1770, respectively). Cyclists involved with alcohol were, in most cases, heavily intoxicated and were not wearing a bicycle helmet. Head injuries were more common among these cyclists than among sober cyclists. As cycling continues to increase, it is important to monitor cycling accidents, improve
Full Text Available Abstract Background A cross sectional study was conducted among 350 sexually active, mainly unemployed men between the ages of 18 and 35 in KwaZulu-Natal. This study examined the psychosocial determinants of the intention to be sexually active after having used marijuana or alcohol personally or in instances when the sexual partner is intoxicated. The theory of planned behaviour and cultural notions of responsible manhood were used in developing the measures. Methods Correlation and hierarchical stepwise linear regression analyses tested determinants of the intention to avoid having sex when personally intoxicated and the intention to avoid sex when the sexual partner is intoxicated. Results About 78 % of the participants reported regular use of alcohol and 39 % indicated ever-using marijuana. A total of 36.3 % used both alcohol and marijuana, and 73 % said that they engaged in multiple sexual partner behaviour. The intention to avoid sex when personally intoxicated as well as the intention to avoid sex when the sexual partner is intoxicated were significantly associated with subjective norms and perceptions of perceived behavioural control towards the respective behaviours, and less with attitudes towards the respective behaviours. Conclusions These findings imply that health education interventions should focus on changing the normative beliefs as well as control beliefs of the target population either directly through education and training or indirectly by creating physical and social environments that facilitate safe sexual practices, for example by organizing positive peer support for risk prevention and by making condoms freely available in community alcohol serving establishments.

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
Full Text Available Aims: Recent research suggests that early onset of intoxication (EOI may be of greater importance for a wide range of subsequent adverse outcomes than early drinking experiences without intoxication. However, research on antecedents of EOI is scarce. The present study identifies predictors of EOI and whether they differ from those of early onset of drinking (EOD. Methods: Data was drawn from the prospective Tracking Opportunities and Problems (TOPP study of Norwegian families (n=382, which followed up mothers and their children with six data collections from childhood (age 1.5 to adolescence (age 14.5. Self-reports from the adolescents (parenting practices, adolescent's conduct problems and friends' deviant behaviour and their mothers (adolescent temperament, socio-economic factors and household alcohol problems were used to identify predictors of EOI and EOD. Findings: A variety of temperamental, socio-economic, and family factors predicted EOI, whereas EOD was predicted of substantially fewer variables. Particularly, when controlling for relevant covariates, low levels of shyness, own conduct problems and having friends with deviant behaviour prospectively predicted EOI, but not EOD. Conclusions: Future research and prevention efforts should take into consideration that EOI and EOD without getting drunk appear to be predicted by different risk factors in childhood and adolescence.

Purpose Few studies have compared acute use of alcohol in suicide decedents with that in a nonsuicide group. This study provides the first national analysis of acute use of alcohol prior to suicide compared with an estimate of acute use of alcohol in a living sample. Methods Pooled 2003-2011 National Violent Death Reporting System data were used to estimate the prevalence of postmortem blood alcohol content positivity (BAC >0.0 g/dl) and intoxication (BAC ≥ 0.08 g/dl). Population estimates of comparable use of alcohol (within the past 48 hours) were based on the National Epidemiologic Survey on Alcohol and Related Conditions. Results Compared to the living sample, male and female suicide decedents showed, respectively, a 1.83- (95% confidence interval [CI], 1.73-1.93) and 2.40-fold (95% CI, 2.24-2.57) increased risk of alcohol ingestion prior to their death after age, race/ethnicity, and chronic alcohol problems were controlled. Furthermore, male and female decedents exhibited, respectively, a 6.18- (95% CI, 5.57-6.86) and a 10.04-fold (95% CI, 8.67-11.64) increased risk of being intoxicated prior to their death after confounders were considered. Conclusions The findings underscore the crucial need to include among the essential components of suicide prevention policies programs that minimize use of alcohol, particularly drinking to intoxication.

Intoxication with calcium antagonists is associated with poor outcome. Even mild calcium antagonist overdose may be fatal. A 51-year-old woman and a 51-year-old man came to the Accident and Emergency Department in severe shock after they had taken a calcium antagonist overdose. After extensive medicinal therapy had failed, they both needed extracorporeal life support (ECLS) as a bridge to recovery. In severe calcium antagonist overdose, the combination of vasoplegia and cardiac failure leads to refractory shock. ECLS temporarily supports the circulation and maintains organ perfusion. In this way ECLS functions as a bridge to recovery and may possibly save lives. Timely consultation with and referral to an ECLS centre is recommended in patients with calcium antagonist overdose.

A 46-year-old man with multiple sclerosis had severe generalised pain for which treatment with paracetamol, ibuprofen, gabapentin and methyl-prednisolone had been unsuccessful. In addition normocytic anaemia without haemolysis and with a normal iron load was found. Due to bright red rectal blood loss and nausea, vomiting, weight loss, anorexia, abdominal pain and constipation a colonoscopy was planned. However, before this was performed, manual slide differentiation of a blood smear showed basophilic stippling and it turned out that the patient had been taking Ayurvedic medication up to one month before presentation. A moderately severe lead intoxication was diagnosed: 0.77 mg/l. The herbal medication had a very high lead content. The patient was successfully treated with the oral lead chelator 23-dimercaptosuccinic acid. Traditional and folk remedies often are important causes of lead poisoning.

Although the misuse of firearms is necessary to the occurrence of firearm violence, there are other contributing factors beyond simply firearms themselves that might also be modified to prevent firearm violence. Alcohol is one such key modifiable factor. To explore this, we undertook a 40-year (1975–2014) systematic literature review with meta-analysis. One large group of studies showed that over one third of firearm violence decedents had acutely consumed alcohol and over one fourth had heavily consumed alcohol prior to their deaths. Another large group of studies showed that alcohol was significantly associated with firearm use as a suicide means. Two controlled studies showed that gun injury after drinking, especially heavy drinking, was statistically significant among self-inflicted firearm injury victims. A small group of studies investigated the intersection of alcohol and firearms laws and alcohol outlets and firearm violence. One of these controlled studies found that off-premise outlets selling takeout alcohol were significantly associated with firearm assault. Additional controlled, population-level risk factor and intervention studies, including randomized trials of which only 1 was identified, are needed. Policies that rezone off-premise alcohol outlets, proscribe blood alcohol levels and enhance penalties for carrying or using firearms while intoxicated, and consider prior drunk driving convictions as a more precise criterion for disqualifying persons from the purchase or possession of firearms deserve further study.

This commentary discusses the study by Marczinski and colleagues in which they used an alcohol priming procedure to examine the effects of an alcohol/energy drink mixture on the priming effect. The significance of the main findings from this study and new avenues of investigation are discussed. Using an alcohol priming paradigm, Marczinski and colleagues report that an alcohol/energy drink combination (AmED) prolongs the desire-to-drink rating compared with alcohol alone. The results of this laboratory study add to the growing body of literature that the intoxicating effects of AmED are different than the intoxication by alcohol alone.

Alcohol use is a key risk factor for young adult mortality and disease, but limited research has focused on high-risk alcohol use among individuals moving from early young adulthood into building and maintaining an initial structure of adult life. This study estimated the prevalence of a range of alcohol use behaviors among US young adults aged 25/26, examined evidence for historical change in prevalence rates, and estimated associations between alcohol use and key demographic, substance use, and adult social role characteristics. Data were obtained from 3542 individuals selected for follow-up from the nationally representative 12th-grade student Monitoring the Future study. Respondents self-reported alcohol use behaviors at age 25/26 during calendar years 2005-2014. Two fifths (39.9%) of young adults aged 25/26 reported being intoxicated at least once in the past 30 days; 25.6% reported usually experiencing a sustained high of 3 or more hours when drinking alcohol. Past-2-week binge drinking (5+ drinks in a row) was reported by 36.3% of respondents. Past-2-week high-intensity drinking (10+ drinks in a row) was reported by 12.4%. These age 25/26 alcohol use prevalence rates remained stable over the 10 years of data examined, in contrast to significant declines over historical time in alcohol prevalence rates among these same individuals at age 18. High-risk drinking was particularly associated with being male, white, unmarried, employed, a nonparent, and an alcohol user before finishing high school. Among US young adults in their mid-20s, alcohol use was highly normative and frequently included participation in high-risk drinking behaviors. High-risk alcohol use prevention approaches developed specifically to reach young adults in their mid-20s are needed, as well as efforts to increase proactive clinician screening to identify young adults participating in high-risk alcohol use.

Acute head trauma (AHT) (caused by motor vehicle accidents that did not produce loss of consciousness or observed brain lesions on CT scan, or falls) was found to result in early (1-8 h after injury) serum deficits in ionized magnesium (IMg2+) and ionized calcium (ICa2+) assessed with ion-selective electrodes (ISEs). Total Mg (TMg) and other electrolytes as well as serum biochemical analytes were all within the normal reference ranges. AHT patients with acute alcohol intoxication (BAC > or = 150 mg/dl) or alcohol abuse (BAC > 200 mg/dl) demonstrated deficits (15-35% less than normal) in IMg2+, but serum TMg levels were normal as were electrolytes and serum biochemical analytes. AHT patients with alcohol intoxication or alcohol abuse required hospitalization for 1-3 days prior to release, whereas AHT patients without alcohol intoxication were released in less than 24 h. The ICa2+/IMg2+ ratio, a sign of increased vascular tone and vascular reactivity, was significantly elevated in AHT patients with alcohol intoxication but not in AHT patients without alcohol intoxication or abuse. These serum divalent cation changes early after traumatic brain injury could be of considerable practicable diagnostic value in the assessment of alcohol-associated head injury. Use of ion-selective electrodes to accurately measure IMg2+ could serve as a logical basis for monitoring the response of the body to AHT.

Single-patient methanol intoxications are a common clinical presentation, but outbreaks are rare and usually occur in settings in which there is limited access to ethanol and methanol is consumed as a substitute. In this case report, we describe an outbreak of methanol intoxications that was challenging from a public health perspective and discuss strategies for managing such an outbreak.

The determinants of alcohol consumption among university students were investigated in a downtown field setting with blood alcohol content (BAC) as the dependent variable. In total, 521 participants completed a brief survey and had their BAC assessed during April 2013. Between 10:00 pm and 2:00 am, teams of researchers recruited passersby at 3 heavy-drinking locations near a university campus. Before the BAC assessment, participants completed a questionnaire regarding their drinking intentions, drinking group, and social anxiety. The average BAC of drinking students was 0.107 g/dL, which was 0.033 g/dL higher than their intended BAC. Males and members of a Greek-life organization consumed significantly more alcohol than their demographic counterparts. A significant positive curvilinear relationship was observed between social anxiety and BAC. University students achieve high levels of intoxication, often exceeding their intended BAC. Social anxiety may be an informative predictor of alcohol consumption in this setting.

To examine short-term consequences associated with consuming alcohol and energy drinks compared with consuming alcohol without energy drinks. A longitudinal measurement-burst design (14-day bursts of daily surveys in four consecutive college semesters) captured both within-person variation across occasions and between-person differences across individuals. The analytic sample of late adolescent alcohol users included 4,203 days with alcohol use across up to four semesters per person from 508 college students. Adding energy drink use to a given day with alcohol use was associated with an increase in number of alcoholic drinks, a trend toward more hours spent drinking, elevated estimated blood alcohol content (eBAC), a greater likelihood of subjective intoxication, and more negative consequences of drinking that day. After controlling for eBAC, energy drink use no longer predicted subjective intoxication but was still associated with a greater number of negative consequences. The consumption of energy drinks may lead to increases in alcohol consumption and, after controlling for eBAC, negative consequences. Use of energy drinks plus alcohol represents an emerging threat to public health. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

To evaluate effects of a training program for owners/managers of alcohol establishments-Alcohol Risk Management (ARM)-on: (i) propensity to sell alcohol to obviously intoxicated patrons; and (ii) changing establishment-level policies/practices. We assigned alcohol establishments randomly to intervention (full-ARM) and delayed-intervention/control (ARM Express) conditions. One large metropolitan area in Midwestern United States. Owners and managers at 231 on-premise alcohol establishments (i.e. bars, restaurants). Training programs consisted of one-to-one sessions with the owner/manager at each establishment. The goal of training was to help owners/managers to select and implement alcohol control policies in their establishments. The full-ARM training consisted of four one-to-one sessions and the ARM Express was a single session. We measured intervention effects through baseline and follow-up pseudo-intoxicated alcohol purchase attempts (i.e. feigning intoxication while attempting to purchase alcohol) and telephone surveys of owners/managers at alcohol establishments. Sales rates to pseudo-intoxicated patrons reduced 23% (relative to delayed-intervention/control condition) at the first follow-up purchase attempt (P = 0.06) but returned to baseline levels 3 months later. On average, establishments selected 13 of 18 recommended policies, but in multivariate models we observed no significant differences at follow-up in reported policies/practices across establishments. Reliance on manager training to promote responsible establishment alcohol policies is not sufficient to prevent illegal alcohol sales to obviously intoxicated patrons and to reduce alcohol-related problems.
Full Text Available Phenytoin is a commonly prescribed antiepileptic drug. Due to its saturation (zero-order pharmacokinetics, phenytoin carries a special risk of dose-related toxicity that is an important issue in emergency medicine. The purpose of this cross-sectional case-series study was to investigate the causes, symptoms, misdiagnoses, and outcomes of acute phenytoin intoxication. It was based on a retrospective chart review of 30 inpatients (mean age, 41.6 ± 22.8 years with 36 episodes of acute phenytoin intoxication at our university hospital in the past 13 years. The average initial serum phenytoin level was 47.3 ± 9.7 μg/mL (range, 27.9-70.4 μg/mL. Excessive self-medication, misunderstanding of the prescription order, and probable drug interaction were the three leading causes of acute phenytoin intoxication. Unsteady gait, dizziness/vertigo, nausea/vomiting, general weakness, and drowsiness were the most common presenting symptoms. The tentative diagnostic accuracy was 67%. The most common initial misdiagnosis was brainstem or cerebellum stroke (14%. The clinical course in all patients was uneventful under temporary withdrawal of phenytoin and supportive care. We concluded that acute phenytoin intoxication was relatively under-diagnosed in the emergency service. Although acute phenytoin intoxication causes no mortality and has a good outcome, the unsteady gait increases the risk of injuries caused by falls. The management of acute phenytoin intoxication includes temporary withdrawal of phenytoin and supportive care.

Studies of alcohol-related harm (violence, injury, illness) suggest that the most significant risk factors are the amount of alcohol consumed and whether obviously intoxicated patrons continue to be served. This study's objective was to investigate the effects of a responsible beverage service (RBS)/enhanced alcohol enforcement intervention on bars, bar patrons, and impaired driving. Two communities-Monroe County, New York, and Cleveland, Ohio-participated in a demonstration program and evaluation. The intervention applied RBS training, targeted enforcement, and corrective actions by law enforcement to a random sample of 10 identified problem bars in each community compared to 10 matched nonintervention problem bars. Data were collected over 3 waves on bar serving practices, bar patron intoxication, drinking and driving, and other alcohol-related harm from intervention and control bars and treatment and comparison communities. In Monroe County, New York, of the 14 outcome measures analyzed, 7 measures showed statistically significant differences from pre- to postintervention. Six of those measures indicated changes in the desired or positive direction and 2 measures were in the undesired or negative direction. Of note in the positive direction, the percentage of intervention bar patrons who were intoxicated decreased from 44 to 27% and the average blood alcohol concentration of patrons decreased from 0.097 to 0.059 g/dL pre- to postintervention. In Cleveland, Ohio, 6 of the 14 measures showed statistically significant changes pre- to postintervention with 6 in the positive direction and 4 in the negative direction. Of note, the percentage of pseudo-intoxicated patrons denied service in intervention bars increased from 6 to 29%. Of the 14 outcome measures that were analyzed in each community, most indicated positive changes associated with the intervention, but others showed negative associations. About half of the measures showed no significance, the sample sizes
It is clear that the ingestion of alcohol can disturb postural measures and it is possible that the effects of alcohol may be manifested at significant stages subsequent to acute intoxication; i.e., during so-called 'hangover' periods. This study was...

Computed tomography (CT of the brain performed immediately was unremarkable. The patient collapsed within the hospital 30 minutes after the CT scan was done, and remained comatose until death, showing no improvement with symptomatic treatment. Magnetic resonance imaging of the brain and spine done 6 days after admission revealed bilaterally symmetrical hyperintensities involving the cerebral and cerebellar cortex and white matter, basal ganglia, thalami, and brainstem on T2-weighted, fluid attenuated inversion recovery and diffusion weighted images; similar hyperintensities were seen involving the swollen and edematous cervical spinal cord and cerebellar tonsillar herniation compressing the proximal cervical cord. Petechial hemorrhages were also noted within the brainstem. These features are compatible with toxic injury to the brain and cervical spinal cord. To our knowledge, the magnetic resonance imaging features of brain and spinal cord injury and cerebellar tonsillar herniation, secondary to isopropanol intoxication have not been reported in the published literature before.Keywords: alcohol intoxication, computed tomography, isopropyl alcohol, ethyl alcohol, toxicity

This study tested the effects of alcohol intoxication and physiological arousal on cognitive biases toward erotic stimuli and condoms. Ninety-seven heterosexual men were randomized to 1 of 6 independent conditions in a 2 (high arousal or control) × 3 (alcohol target BAC = 0.08, placebo, or juice control) design and then completed a variant of the Approach-Avoidance Task (AAT). The AAT assessed reaction times toward approaching and avoiding erotic stimuli and condoms with a joystick. Consistent with hypotheses, the alcohol condition exhibited an approach bias toward erotic stimuli, whereas the control and placebo groups exhibited an approach bias toward condom stimuli. Similarly, the participants in the high arousal condition exhibited an approach bias toward erotic stimuli and the low arousal control condition exhibited an approach bias toward condoms. The results suggest that acute changes in intoxication and physiological arousal independently foster biased responding toward sexual stimuli and these biases are associated with sexual risk intentions.

This article provides information on the amount of alcohol consumed by students during college sports events. It examines the relationship between alcohol consumption and the rank of the match, sex of the players (male vs. female league), and sex of the spectators. The study was carried out during an interdepartmental volleyball championship (cup system) at the University of Warmia and Mazury in Olsztyn (Poland), which included 16 matches (in both male and female leagues). The research sample consisted of 2,683 students between ages 19 and 24 years (including 1,768 men and 915 women) who came to cheer on their peers at the matches. Two objective measurements of alcohol consumption were used: (a) the number of empty alcohol packages left behind by the spectators at the sports facilities after each match and (b) breath alcohol analysis tests given to volunteering spectators after each match (in which 323 persons consented to participate). Male league games were accompanied by more alcohol consumption than were female league games, and male spectators drank more than female spectators. The most drinking occurred among men watching the male league, and the least amount of drinking occurred among women watching the female league. Alcohol intoxication increased with the rank of the match mostly among men watching the male league. The sex of players and spectators seems to be a mediating factor in the relationship between the rank of a match and the amount of alcohol consumed.
Full Text Available Abstract Background Inpatient care for alcohol intoxication is increasing in Sweden, especially among young women. Since it is well known that alcohol disorder is a chronic relapsing illness, this study examines the extent to which people return for more care. Method All inpatients with alcohol-related diagnoses in Stockholm County during 1997 were followed prospectively to 2007 through registers. The proportion reappearing for the same diagnosis, other alcohol-related inpatient, or outpatient care each year after baseline, as well as the number of years the inpatients reappeared were calculated (n = 2735. Three diagnoses were examined separately; alcohol dependence, harmful use of alcohol, and alcohol intoxication. Results Three out of five inpatients with an alcohol diagnoses reappeared for more alcohol-related inpatient care during the following decade. The proportion returning was largest the year after baseline and then decreased curvilinearly over time. The inclusion of outpatient care increased proportions, but did not change patterns. Of those with an alcohol dependence diagnosis at baseline 42 percent returned for more alcohol-related inpatient care the first, 28 percent the fifth, and 25 percent the tenth year. Corresponding proportions for harmful use and intoxication were smaller. One in five among those with an alcohol dependence returned for more than five of the ten years. Ordered logistic regressions confirmed that besides diagnosis, age and gender were independently related to the number of years returning to care. Conclusions While middle-aged males with alcohol dependence were in a revolving door, young female inpatients with intoxication diagnosis returned to a comparably lower degree.

The Monkey Alcohol Tissue Research Resource (MATRR) is a repository and analytics platform for detailed data derived from well-documented nonhuman primate (NHP) alcohol self-administration studies. This macaque model has demonstrated categorical drinking norms reflective of human drinking populations, resulting in consumption pattern classifications of very heavy drinking (VHD), heavy drinking (HD), binge drinking (BD), and low drinking (LD) individuals. Here, we expand on previous findings that suggest ethanol drinking patterns during initial drinking to intoxication can reliably predict future drinking category assignment. The classification strategy uses a machine-learning approach to examine an extensive set of daily drinking attributes during 90 sessions of induction across 7 cohorts of 5 to 8 monkeys for a total of 50 animals. A Random Forest classifier is employed to accurately predict categorical drinking after 12 months of self-administration. Predictive outcome accuracy is approximately 78% when classes are aggregated into 2 groups, "LD and BD" and "HD and VHD." A subsequent 2-step classification model distinguishes individual LD and BD categories with 90% accuracy and between HD and VHD categories with 95% accuracy. Average 4-category classification accuracy is 74%, and provides putative distinguishing behavioral characteristics between groupings. We demonstrate that data derived from the induction phase of this ethanol self-administration protocol have significant predictive power for future ethanol consumption patterns. Importantly, numerous predictive factors are longitudinal, measuring the change of drinking patterns through 3 stages of induction. Factors during induction that predict future heavy drinkers include being younger at the time of first intoxication and developing a shorter latency to first ethanol drink. Overall, this analysis identifies predictive characteristics in future very heavy drinkers that optimize intoxication, such as having
Full Text Available Ethanol intoxication is a commonly known risk factor of a crime, especially in the case of those who drank alcohol within 24 hours before perpetrating a homicide or the victim’s severe body injury. This study is an attempt to characterize the perpetrators of a homicide or the victim’s severe body injury during ethanol intoxication. The examined group consisted of 90 suspects in the public prosecutor’s investigation for an offence which threatened health or life, qualified pursuant to the penal code as a homicide, attempted homicide, or severe body injury. The subjects underwent a sex-week forensic psychiatry observation during 2004-2008 at the Forensic Psychiatry Unit in High Security Prison No 2 in Lodz. Analysed retrospectively was the medical documentation collected during the forensic psychiatry observation, including available medical documentation and categorical forensic psychiatry opinions issued by two expert psychiatrists. According to the collected materials, it was established that most perpetrators (78% of subjects who during ethanol intoxication committed a homicide or severe body injury were men aged 18-75 years (the subjects’ mean age reached 42 years, unemployed, divorced or unmarried, who did not undergo or discontinued the military service, had been punished with a court sentence, or manifested aggressive behaviours in the past.

The aim of this study was to examine differences in alcohol consumption and its consequences when consumed alone and when mixed with energy drinks. A survey was conducted among Dutch students at Utrecht University and the College of Utrecht. We collected data on alcohol consumption and alcohol-related consequences of alcohol consumed alone and/or alcohol mixed with energy drinks (AMED). The data were analyzed using a retrospective within-subject design, comparing occasions when subjects consumed AMED with those when they consumed alcohol only in the past 30 days. A representative sample of 6002 students completed the survey, including 1239 who consumed AMED. Compared with consuming alcohol only, when consuming AMED, students consumed significantly fewer alcoholic drinks on an average drinking day (6.0 versus 5.4, respectively), and reported significantly fewer drinking days in the previous month (9.2 versus 1.4), significantly fewer days being drunk (1.9 versus 0.5), and significantly fewer occasions of consuming more than four (female)/five (male) alcoholic drinks (4.7 versus 0.9). The maximum number of mixed alcoholic drinks (4.5) in the previous month was significantly lower when compared with occasions when they consumed alcohol only (10.7). Accordingly, the mean duration of a drinking session was significantly shorter when mixing alcoholic drinks (4.0 versus 6.0 hours). Finally, when consuming AMED, significantly fewer alcohol-related consequences were reported (2.6) for the previous year, including driving a car while intoxicated, taking foolish risks, or being injured or hurt, as compared with alcohol-related consequences when consuming alcohol only (4.9). Mixing alcohol with energy drinks decreases overall alcohol consumption, and decreases the likelihood of experiencing negative alcohol-related consequences.

Abuse of the psychoactive "designer drug" methylenedioxypyrovalerone (MDPV) has become a serious international public health concern because of the severity of its physical and behavioral toxicities. MDPV is the primary ingredient in so-called "bath salts," labeled as such to avoid criminal prosecution and has only been classified recently as a controlled substance in the United States and some other countries. However, it remains a danger because of illegal sources, including the Internet. MDPV is a synthetic, cathinone-derivative, central nervous system stimulant and is taken to produce a cocaine- or methamphetamine-like high. Administered via oral ingestion, nasal insufflation, smoking, intravenous or intramuscular methods, or the rectum, the intoxication lasts 6 to 8 hours and has high addictive potential. Overdoses are characterized by profound toxicities, causing increased attention by emergency department and law enforcement personnel. Physical manifestations range from tachycardia, hypertension, arrhythmias, hyperthermia, sweating, rhabdomyolysis, and seizures to those as severe as stroke, cerebral edema, cardiorespiratory collapse, myocardial infarction, and death. Behavioral effects include panic attacks, anxiety, agitation, severe paranoia, hallucinations, psychosis, suicidal ideation, self-mutilation, and behavior that is aggressive, violent, and self-destructive. Treatment is principally supportive and focuses on counteracting the sympathetic overstimulation, including sedation with intravenous benzodiazepines, seizure-prevention measures, intravenous fluids, close (eg, intensive care unit) monitoring, and restraints to prevent harm to self or others. Clinical presentation is often complicated by coingestion of other psychoactive substances that may alter the treatment approach. Clinicians need to be especially vigilant in that MDPV is not detected by routine drug screens and overdoses can be life-threatening. Copyright © 2012 Elsevier Inc. All rights

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.

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

The purpose of the study was to determine the characteristics of endogenous intoxication parameters, biochemical protection and reveal their interaction in children with celiac disease. 81 children aged from 1 to 16 years with celiac disease were examined in acute and remission periods. In erythrocytes, blood serum and urine we determined low and moderate molecular weight substances (LMMWS), oligopeptides OP); in erythrocytes--the value of erythrocyte mechanical hemolysis (MH), malondialdehyde (MDA) content, the activity of glutathione reductase GR) and superoxide dismutase (SOD); in blood serum--ceruloplasmin (CP) level, alcohol dehydrogenase (ADH) activity; in erythrocytes and blood serum--glutathione transferase (GT), and calculated intoxication index (II). In children with celiac disease in acute and remission periods LMMWS, OP, II levels in blood were statistically significantly high, while LMMWS level in urine was low. In both periods MH activity was high (p < 0.001), and GSR (p < 0.001) and SOD (p < 0.01) levels were low. We revealed the correlation between MDA and II (r = 0.67; p = 0.006), erythrocyte LMMWS and SOD (r = -0.61; p = 0.015), erythrocyte LMMWS and ADH (r = 0.62; p = 0.006), between GT and OP in urine (r = -0.31; p = 0.026), GTand MDA (r = 0.68; p = 0.000), GT and MH (r = -0.46; p = 0.004), between MDA and CP (r = 0.57; p = 0.002) that made it possible to develop the models of dependence of the parameters in relation to each other. In celiac disease there is endogenous intoxication. The changes of the first and the second phases of biotransformation, antioxidant protection is an essential factor of the disease pathogenesis, since they have an effect on endogenous intoxication formation that should be taken into consideration in therapy.

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

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

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

There is no research examining alcohol-related aggression and anti-social behaviour in UK or European sportspeople (athletes), and no research has examined relationships between masculinity, alcohol consumption, and alcohol-related aggression and antisocial behaviour in sportspeople (athletes). This study addresses this gap. Cross-sectional. A sample (N=2048; women=892, 44%) of in season sportspeople enrolled at UK universities (response 83%), completed measures of masculinity, alcohol consumption, within-sport (on-field) violence, and having been the perpetrator and/or victim of alcohol-related violent/aggressive and antisocial behaviour (e.g., hit/assaulted, vandalism, sexual assault). Logistic regressions examined predictors of alcohol-related violence/aggression and anti-social behaviours. Significant bivariate relationships between masculinity, within-sport violence, alcohol consumption, and alcohol-related aggression and anti-social behaviour were found for both men and women (p'smasculinity and alcohol consumption in men and women were related to an increased odds of having conducted an aggressive, violent and/or anti-social act in the past 12 months when intoxicated. Odds ratios were largest for relationships between masculinity, alcohol consumption, within-sport violence, and interpersonal violence/aggression (p'smasculinity and excessive drinking. Interventions that reduce excessive alcohol consumption, masculine norms and associated within-sport violence, could be effective in reducing alcohol-related aggression and antisocial behaviour in UK sportspeople.

Background Alcohol cues can bias attention and elicit emotional reactions, especially in drinkers. Yet, little is known about how alcohol cues affect explicit and implicit memory processes, and how memory for alcohol cues is affected by acute alcohol intoxication. Methods Young adult participants (N=161) were randomly assigned to alcohol, placebo, or control beverage conditions. Following beverage consumption, they were shown neutral, emotional and alcohol-related pictures cues. Participants then completed free recall and repetition priming tasks to test explicit and implicit memory, respectively, for picture cues. Average blood alcohol concentration for the alcohol group was 74 ± 13 mg/dl when memory testing began. Two mixed linear model analyses were conducted to examine the effects of beverage condition, picture cue type, and their interaction on explicit and implicit memory. Results Picture cue type and beverage condition each significantly affected explicit recall of picture cues, whereas only picture cue type significantly influenced repetition priming. Individuals in the alcohol condition recalled significantly fewer pictures than those in other conditions, regardless of cue type. Both free recall and repetition priming were greater for emotional and alcohol-related cues compared to neutral picture cues. No interaction effects were detected. Conclusions Young adult drinkers showed enhanced explicit and implicit memory processing of alcohol cues compared to emotionally neutral cues. This enhanced processing for alcohol cues was on par with that seen for positive emotional cues. Acute alcohol intoxication did not alter this preferential memory processing for alcohol cues over neutral cues. PMID:26811126

Six male and four female healthy volunteers were given oral placebo (glucose capsule and orange juice), cannabidiol (CBD 200 mg capsule and orange juice), alcohol (1 g/kg in orange juice and glucose capsule), and CBD (200 mg capsule) plus alcohol (1 g/kg in orange juice) in a double-blind, crossover, randomized design. Treatments were spaced one week apart. Parameters measured were a finger tap test (motor performance), cancellation and differential aptitude tests (psychomotor performance), a 1-min time production task, subjective effects (66 item adjective-pair semantic differential), and breathalyzer estimations of blood alcohol levels. Compared to placebo, alcohol and alcohol plus CBD, but not CBD alone, produced significant impairments of motor and psychomotor performances, overestimations of time production and subjective responses indicating an accurate self-perception of their intoxication and deficits. The combination of alcohol plus CBD resulted in significantly lower blood alcohol levels compared to alcohol given alone, however, there were few differences observed between the pharmacological effects of the two alcohol conditions. Thus, the inactivity of CBD, a major marijuana constituent, on motor and mental performance and effects also extends to its interaction with alcohol.

The present study sought to further understand the association between caffeinated alcoholic beverage (CAB) use and alcohol-related risks. In particular, we focused on the role of two identified expectancies specific to CAB use: intoxication enhancement and avoidance of negative consequences. Although outcome expectancies are consistent predictors of substance use, limited research has examined expectancies related to CAB use and their association with alcohol-related behaviors, such as protecting themselves from alcohol-related harms. Consequently, the present study examined CAB-specific expectancies and protective behavioral strategies (PBS) as mediators of CAB use and negative consequences. Participants were 322 (219 women) college drinkers who completed self-report measures of typical CAB and alcohol use, CAB-specific expectancies, PBS use, and alcohol-related harms. Structural equation modeling revealed, after controlling for typical non-CAB heavy alcohol use, a significant indirect effect of CAB use to alcohol-related problems through avoidance of negative consequences CAB expectancies and PBS use. However, intoxication enhancement expectancies did not mediate this association. Our findings indicate that heavier CAB use was associated with stronger expectations that drinking CABs can help avoid negative consequences. These beliefs were related to using fewer PBS when drinking and a greater likelihood of experiencing problems. Given that these expectancies may be underlying mechanisms of CAB use, their inclusion in existing alcohol interventions may be beneficial. Copyright © 2015 Elsevier Ltd. All rights reserved.

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.

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.

Two case reports of Datura stramonium intoxications are presented. The first one was a self poisoning, with a moderate anticholinergic syndrome and a spontaneous improvement. The second one was a recreational use of Datura stramonium for its hallucinogenic properties. The anticholinergic syndrome was marked and the improvement required orotracheal intubation, mechanical ventilation, intraveinous rehydratation, and active cooling to prevent organ failure.

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.

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.
Full Text Available We used animal model of neurotoxicity in rats, which provided the possibility of studying biological pathophysiological phenomena in vivo and afterwards in vitro conditions. The analysis of electrocortical brain activity using mathematical methods can describe the changes induced by aluminum intoxication in rat as an animal model. In physiological and pathophysiological conditions, on experimental models, mechanisms related to changes in behavior, plasticity and accumulation of aluminum in nervous tissue of the rat brain were observed. Animal models of rats used in the experiments described changes in the group of neuronal activity in the brain of rats in different modes of intoxication aluminum. This study describes ECoG activity in the brain of rats under anesthesia in both the control and aluminum treated animals. Fractal and spectral analysis was used to present qualitative and quantitative changes in the conditions of neurotoxicity. Changes in neurotransmission, as well as the structure and function of the neural network are connected to the molecular-physiological mechanisms of neurotoxicity. Aluminium toxicity was monitored through changes in glutamatergic activity and calcium channel activity. By spectrum analysis neurotoxicity was described through changes in spectral power in the corresponding frequency ranges. By comparing the FD of intoxicated and control individuals there was obtained the range of the change in correlation with the corresponding pathophysiological conditions of intoxication. The shange in FD might be an indication of neurotoxicity.

Combining energy drinks (such as 'Red Bull(®)') with alcohol is becoming increasingly popular, particularly among young people. However, as yet, limited research has been conducted examining the harms associated with this form of drinking. To review current evidence associated with combining energy drinks with alcohol and provide recommendations for addressing this issue within primary care. Combining alcohol with energy drinks can mask the signs of alcohol intoxication, resulting in greater levels of alcohol intake, dehydration, more severe and prolonged hangovers, and alcohol poisoning. It may also increase engagement in risky behaviours (such as drink driving) as well as alcohol related violence. General practitioners should be aware of the harms associated with this pattern of drinking, and provide screening and relevant harm reduction advice.

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.

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

Although the misuse of firearms is necessary to the occurrence of firearm violence, there are other contributing factors beyond simply firearms themselves that might also be modified to prevent firearm violence. Alcohol is one such key modifiable factor. To explore this, we undertook a 40-year (1975-2014) systematic literature review with meta-analysis. One large group of studies showed that over one third of firearm violence decedents had acutely consumed alcohol and over one fourth had heavily consumed alcohol prior to their deaths. Another large group of studies showed that alcohol was significantly associated with firearm use as a suicide means. Two controlled studies showed that gun injury after drinking, especially heavy drinking, was statistically significant among self-inflicted firearm injury victims. A small group of studies investigated the intersection of alcohol and firearms laws and alcohol outlets and firearm violence. One of these controlled studies found that off-premise outlets selling takeout alcohol were significantly associated with firearm assault. Additional controlled, population-level risk factor and intervention studies, including randomized trials of which only 1 was identified, are needed. Policies that rezone off-premise alcohol outlets, proscribe blood alcohol levels and enhance penalties for carrying or using firearms while intoxicated, and consider prior drunk driving convictions as a more precise criterion for disqualifying persons from the purchase or possession of firearms deserve further study. © The Author 2016.

This study develops and tests a new conceptual model of perceived physical availability of alcohol at work that provides unique insight into three dimensions of workplace physical availability of alcohol and their direct and indirect relations to workplace alcohol use and impairment. Data were obtained from a national probability sample of 2,727 U.S. workers. The results support the proposed conceptual model and provide empirical support for a positive relation of perceived physical availability of alcohol at work to workplace alcohol use and two dimensions of workplace impairment (workplace intoxication and workplace hangover). Ultimately, the findings suggest that perceived physical availability of alcohol at work is a risk factor for alcohol use and impairment during the workday, and that this relation is more complex than previously hypothesized.

Alcohol's effects on executive functioning are well documented. Research in this area has provided much information on both the acute and chronic effects of alcohol on processes such as working memory and mental flexibility. However, most research on the acute effects of alcohol is conducted with individuals older than 21 years of age. Using field recruitment methods can provide unique empirical data on the acute effects of alcohol on an underage population. The current study examined the independent effects of acute alcohol intoxication (measured by breath alcohol content) and chronic alcohol use (measured by years drinking) on a test of visuomotor performance and mental flexibility (Trail Making Test) among 91 drinkers ages 18-20 years recruited from a field setting. Results show that breath alcohol predicts performance on Trails B, but not on Trails A, and that years drinking, above and beyond acute intoxication, predicts poorer performance on both Trails A and B. These data suggest that, independent of the acute effects of alcohol, chronic alcohol consumption has deleterious effects on executive functioning processes among underage drinkers. Our discussion focuses on the importance of these data in describing the effect of alcohol on adolescents and the potential for engaging in risky behavior while intoxicated.

Two stages of alcohol intoxication were detected in an experiment on 21 rats during formation of addiction to alcohol. It has been shown that the emotiogenic hypothalamic zones may play the part of trigger mechanisms with infolvement of limbic and neocortical apparatuses. At the same time a different type of integration of addiction to alcohol food is possible, in which the emotiogenic zones do not play the principal part. The late stages of formation of addiction to alcohol are characterized by EEG hypersynchronia with a qualitatively different structure in the periods of abstinence and "saturation" with alcohol. A close connection has been recorded between the mechanisms of emotion, hypersynchronia and behavioral epileptic phenomena.

Alcohol consumption among adolescents is a serious public health problem in South Korea. Our study examined the relationship between alcohol consumption and academic achievement in Korean adolescents. In 2011, 75,643 students from seventh to twelfth grade participated in the Seventh Korea Youth Risk Behaviour Web-based Survey (KYRBWS-VII). We performed multivariate logistic regression analysis to examine the associations between alcohol consumption, frequency of severe alcohol intoxication, and academic achievement for both girls and boys. Compared to non-drinkers, the odds of achieving average or higher academic performance significantly decreased for both boys and girls with increasing number of days per month with reported alcohol consumption (p≤0.008). Further, odds of achieving average or higher academic performance significantly decreased with increasing amounts of alcohol consumed compared to non-drinkers (p≤0.026). Additionally, the odds of achieving average or higher academic performance according to the frequency of severe alcohol intoxication were only significantly decreased for 1-2 days per month of severe intoxication (pacademic achievement in Korea. To improve academic achievement, we recommend interventions that reduce alcohol consumption among adolescents. Copyright© by the National Institute of Public Health, Prague 2015.

Exposure to household products is very common, but in industrialized countries severe or fatal poisoning with household products is rare today, due to the legal restriction of sale of hazardous household products. The big challenge for physicians, pharmacologists and toxicologists is to identify the few exceptional life-threatening situations where immediate intervention is needed. Among thousands of innocuous products available for the household only very few are hazardous. Substances found in these products include detergents, corrosives, alcohols, hydrocarbons, and some of the essential oils. The ingestion of batteries and magnets and the exposure to cyanoacrylates (super glue) can cause complications in exceptional situations. Among the most dangerous substances still present in household products are ethylene glycol and methanol. These substances cause major toxicity only through their metabolites. Therefore, initial symptoms may be only mild or absent. Treatment even in asymptomatic patients has to be initiated as early as possible to inhibit production of toxic metabolites. For all substances not only the compound itself but also the route of exposure is relevant for toxicity. Oral ingestion and inhalation generally lead to most pronounced symptoms, while dermal exposure is often limited to mild irritation. However, certain circumstances need special attention. Exposure to hydrofluoric acid may lead to fatal hypocalcemia, depending on the concentration, duration of exposure, and area of the affected skin. Accidents with hydrocarbon pressure injectors and spray guns are very serious events, which may lead to amputation of affected limbs. Button batteries normally pass the gastrointestinal tract without problems even in toddlers; in rare cases, however, they get lodged in the esophagus with the risk of localized tissue damage and esophageal perforation.

This review discusses the available scientific evidence on the effects of mixing energy drinks with alcohol.Methods: A literature search was performed using the keywords “energy drink and Red Bull®” and consulting Medline/Pubmed, PsycINFO, and Embase.Results: There is little evidence that energy drinks antagonize the behavioral effects of alcohol, and there is no consistent evidence that energy drinks alter the perceived level of intoxication of people who mix energy drinks with alcohol. No clinically relevant cardiovascular or other adverse effects have been reported for healthy subjects combining energy drinks with alcohol, although there are no long-term investigations currently available. Finally, whilst several surveys have shown associations, there is no direct evidence that coadministration of energy drinks increases alcohol consumption, or initiates drug and alcohol dependence or abuse.Conclusion: Although some reports suggest that energy drinks lead to reduced awareness of intoxication and increased alcohol consumption, a review of the available literature shows that these views are not supported by direct or reliable scientific evidence. A personality with higher levels of risk-taking behavior may be the primary reason for increased alcohol and drug abuse per se. The

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)

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

A study of amoxicillin pharmacokinetics was conducted in healthy goats and goats with chronic lead intoxication. The intoxicated goats had increased serum concentrations of liver enzymes (alanine aminotransferase and γ-glutamyl transferase), blood urea nitrogen, and reactivated δ-aminolevulinic acid dehydratase compared to the controls. Following intravenous amoxicillin (10 mg/kg bw) in control and lead-intoxicated goats, elimination half-lives were 4.14 and 1.26 h, respectively. The volumes of distribution based on the terminal phase were 1.19 and 0.38 L/kg, respectively, and those at steady-state were 0.54 and 0.18 L/kg, respectively. After intramuscular (IM) amoxicillin (10 mg/kg bw) in lead-intoxicated goats and control animals, the absorption, distribution, and elimination of the drug were more rapid in lead-intoxicated goats than the controls. Peak serum concentrations of 21.89 and 12.19 µg/mL were achieved at 1 h and 2 h, respectively, in lead-intoxicated and control goats. Amoxicillin bioavailability in the lead-intoxicated goats decreased 20% compared to the controls. After amoxicillin, more of the drug was excreted in the urine from lead-intoxicated goats than the controls. Our results suggested that lead intoxication in goats increases the rate of amoxicillin absorption after IM administration and distribution and elimination. Thus, lead intoxication may impair the therapeutic effectiveness of amoxicillin. PMID:23820209

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.)

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...

Intoxication often prevents clinical clearance of the cervical spine (Csp) after trauma leading to prolonged immobilization even with a normal computed tomography (CT) scan. We evaluated the accuracy of CT at detecting clinically significant Csp injury, and surveyed participants on related opinions and practice. A prospective multicenter study (2013-2015) at 17 centers. All adult blunt trauma patients underwent structured clinical examination and imaging including a Csp CT, with follow-up thru discharge. alcohol- and drug-intoxicated patients (TOX+) were identified by serum and/or urine testing. Primary outcomes included the incidence and type of Csp injuries, the accuracy of CT scan, and the impact of TOX+ on the time to Csp clearance. A 36-item survey querying local protocols, practices, and opinions in the TOX+ population was administered. Ten thousand one hundred ninety-one patients were prospectively enrolled and underwent CT Csp during the initial trauma evaluation. The majority were men (67%), had vehicular trauma or falls (83%), with mean age of 48 years, and mean Injury Severity Score (ISS) of 11. The overall incidence of Csp injury was 10.6%. TOX+ comprised 30% of the cohort (19% EtOH only, 6% drug only, and 5% both). TOX+ were significantly younger (41 years vs. 51 years; p 12 hrs) in 25%. The survey showed marked variations in protocols, definitions, and Csp clearance practices among participating centers, although 100% indicated willingness to change practice based on these data. For intoxicated patients undergoing Csp imaging, CT scan was highly accurate and reliable for identifying clinically significant spine injuries, and had a 100% NPV for identifying unstable injuries. CT-based clearance in TOX+ patients appears safe and may avoid unnecessary prolonged immobilization. There was wide disparity in practices, definitions, and opinions among the participating centers. Diagnostic tests or criteria, level II.

Excessive alcohol consumption is responsible for considerable harm from chronic disease and injury. Within most developed countries, members of sporting clubs participate in at-risk alcohol consumption at levels above that of communities generally. There has been limited research investigating the predictors of at-risk alcohol consumption in sporting settings, particularly at the non-elite level. The purpose of this study was to examine the association between the alcohol management practices and characteristics of community football clubs and at-risk alcohol consumption by club members. A cross sectional survey of community football club management representatives and members was conducted. Logistic regression analysis (adjusting for clustering by club) was used to determine the association between the alcohol management practices (including alcohol management policy, alcohol-related sponsorship, availability of low- and non-alcoholic drinks, and alcohol-related promotions, awards and prizes) and characteristics (football code, size and location) of sporting clubs and at-risk alcohol consumption by club members. Members of clubs that served alcohol to intoxicated people [OR: 2.23 (95% CI: 1.26-3.93)], conducted 'happy hour' promotions [OR: 2.84 (95% CI: 1.84-4.38)] or provided alcohol-only awards and prizes [OR: 1.80 (95% CI: 1.16-2.80)] were at significantly greater odds of consuming alcohol at risky levels than members of clubs that did not have such alcohol management practices. At-risk alcohol consumption was also more likely among members of clubs with less than 150 players compared with larger clubs [OR:1.45 (95% CI: 1.02-2.05)] and amongst members of particular football codes. The findings of this study suggest a need and opportunity for the implementation of alcohol harm reduction strategies targeting specific alcohol management practices at community football clubs.

The recurring dilemma of having to deal with an intoxicated person in possession of a gun uttering homicidal or suicidal threats along with the current debate on gun control prompted this controlled survey of the characteristics of individuals with problems arising from the joint abuse of alcohol and possession of a gun. A comparison of the data point to violence as being the most significant differentiating variable involved. This violent potential was reflected by the presence among the alcoholics involved of more past and present antisocial traits, a higher rating on the Nicol's scale of violence, more offences committed against the person and homicidal behaviour. The availability of a gun was a significant factor. No correlation was found between the severity of the drinking problem and the risk of dangerous handling of a gun. The need for more stringent gun controls is supported but their implications to the physician and especially the psychiatrist as a potential guarantor for a licence application ought to be further explored by the professional bodies involved.
Full Text Available Ricin, a plant-derived toxin originating from the seeds of Ricinus communis (castor beans, is one of the most lethal toxins known, particularly if inhaled. Ricin is considered a potential biological threat agent due to its high availability and ease of production. The clinical manifestation of pulmonary ricin intoxication in animal models is closely related to acute respiratory distress syndrome (ARDS, which involves pulmonary proinflammatory cytokine upregulation, massive neutrophil infiltration and severe edema. Currently, the only post-exposure measure that is effective against pulmonary ricinosis at clinically relevant time-points following intoxication in pre-clinical studies is passive immunization with anti-ricin neutralizing antibodies. The efficacy of this antitoxin treatment depends on antibody affinity and the time of treatment initiation within a limited therapeutic time window. Small-molecule compounds that interfere directly with the toxin or inhibit its intracellular trafficking may also be beneficial against ricinosis. Another approach relies on the co-administration of antitoxin antibodies with immunomodulatory drugs, thereby neutralizing the toxin while attenuating lung injury. Immunomodulators and other pharmacological-based treatment options should be tailored according to the particular pathogenesis pathways of pulmonary ricinosis. This review focuses on the current treatment options for pulmonary ricin intoxication using anti-ricin antibodies, disease-modifying countermeasures, anti-ricin small molecules and their various combinations.

Cholera toxin (CT) enters and intoxicates host cells after binding cell surface receptors via its B subunit (CTB). We have recently shown that in addition to the previously described binding partner ganglioside GM1, CTB binds to fucosylated proteins. Using flow cytometric analysis of primary human jejunal epithelial cells and granulocytes, we now show that CTB binding correlates with expression of the fucosylated Lewis X (LeX) glycan. This binding is competitively blocked by fucosylated oligosaccharides and fucose-binding lectins. CTB binds the LeX glycan in vitro when this moiety is linked to proteins but not to ceramides, and this binding can be blocked by mAb to LeX. Inhibition of glycosphingolipid synthesis or sialylation in GM1-deficient C6 rat glioma cells results in sensitization to CT-mediated intoxication. Finally, CT gavage produces an intact diarrheal response in knockout mice lacking GM1 even after additional reduction of glycosphingolipids. Hence our results show that CT can induce toxicity in the absence of GM1 and support a role for host glycoproteins in CT intoxication. These findings open up new avenues for therapies to block CT action and for design of detoxified enterotoxin-based adjuvants.
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.
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.

Alcohol intoxication and overserving of alcohol at sporting events are of great concern, given the relationships between alcohol consumption, public disturbances, and violence. During recent years this matter has been on the agenda for Swedish policymakers, authorities and key stakeholders, with demands that actions be taken. There is promising potential for utilizing an environmental approach to alcohol prevention as a strategy to reduce the level of alcohol intoxication among spectators at sporting events. Examples of prevention strategies may be community mobilization, Responsible Beverage Service training, policy work, and improved controls and sanctions. This paper describes the design of a quasi-experimental control group study to examine the effects of a multi-component community-based alcohol intervention at matches in the Swedish Premier Football League. A baseline assessment was conducted during 2015 and at least two follow-up assessments will be conducted in 2016 and 2017. The two largest cities in Sweden are included in the study, with Stockholm as the intervention area and Gothenburg as the control area. The setting is Licensed Premises (LP) inside and outside Swedish football arenas, in addition to arena entrances. Spectators are randomly selected and invited to participate in the study by providing a breath alcohol sample as a proxy for Blood Alcohol Concentration (BAC). Actors are hired and trained by an expert panel to act out a standardized scene of severe pseudo-intoxication. Four types of cross-sectional data are generated: (i) BAC levels among ≥ 4 200 spectators, frequency of alcohol service to pseudo-intoxicated patrons attempting to purchase alcohol at LP (ii) outside the arenas (≥200 attempts) and (iii) inside the arenas (≥ 200 attempts), and (iv) frequency of security staff interventions towards pseudo-intoxicated patrons attempting to enter the arenas (≥ 200 attempts). There is an urgent need nationally and internationally to

Full Text Available The sensitivity to the intoxicating effects of alcohol as well as its adverse medical consequences differ markedly among individuals, which reflects in part differences in alcohol's absorption, distribution, metabolism, and elimination (ADME properties. The ADME of alcohol in the body and its relationship with alcohol's brain bioavailability, however, is not well understood.The ADME of C-11 labeled alcohol, CH(3 (11CH(2OH, 1 and C-11 and deuterium dual labeled alcohol, CH(3 (11CD(2OH, 2 in baboons was compared based on the principle that C-D bond is stronger than C-H bond, thus the reaction is slower if C-D bond breaking occurs in a rate-determining metabolic step. The following ADME parameters in peripheral organs and brain were derived from time activity curve (TAC of positron emission tomography (PET scans: peak uptake (C(max; peak uptake time (T(max, half-life of peak uptake (T(1/2, the area under the curve (AUC(60 min, and the residue uptake (C(60 min.For 1 the highest uptake occurred in the kidney whereas for 2 it occurred in the liver. A deuterium isotope effect was observed in the kidneys in both animals studied and in the liver of one animal but not the other. The highest uptake for 1 and 2 in the brain was in striatum and cerebellum but 2 had higher uptake than 1 in all brain regions most evidently in thalamus and cingulate. Alcohol's brain uptake was significantly higher when given intravenously than when given orally and also when the animal was pretreated with a pharmacological dose of alcohol.The study shows that alcohol metabolism in peripheral organs had a large effect on alcohol's brain bioavailability. This study sets the stage for clinical investigation on how genetics, gender and alcohol abuse affect alcohol's ADME and its relationship to intoxication and medical consequences.

Alcohol is usually consumed in social contexts. However, the drug has been studied mainly under socially isolated conditions, and our understanding of how social setting affects response to alcohol is limited. The current study compared the subjective, physiological, and behavioral effects of a moderate dose of alcohol in moderate social drinkers who were tested in either a social or an isolated context and in the presence of others who had or had not consumed alcohol. Healthy men and women were randomly assigned to either a social group tested in pairs (SOC; N = 24), or an isolated group tested individually (ISO; N = 20). They participated in four sessions, in which they received oral alcohol (0.8 g/kg) or placebo on two sessions each, in quasi-randomized order under double-blind conditions. In the SOC condition, the drug conditions of the co-participants were varied systematically: on two sessions, both participants received the same substance (placebo or alcohol) and on the other two sessions one received alcohol while the other received placebo. Cardiovascular measures, breath alcohol levels, and mood were assessed at regular intervals, and measures of social interaction were obtained in the SOC group. Alcohol produced greater effects on certain subjective measures in the SOC condition compared with the ISO condition, including feelings of intoxication and stimulation, but not on other measures such as feeling sedated or high, or on cardiovascular measures. Within the SOC condition, participants rated themselves as more intoxicated when their partner received alcohol, and paired subjects interacted more when at least one participant received alcohol. The presence of others enhances some of the subjective and behavioral effects of alcohol, especially the presence of another intoxicated individual. This enhancement of alcohol effects may explain, in part, why it is used in a social context.
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.

Poisoning is a frequent disease in an emergency division. During four years we observed patients with poisoning related to there reason of intoxication, the degree of severity, age group and sex, and tried to make conclusions about lethal outcome on behalf of our data. The severity was defined by the «poison severity scale» (PSS). 1515 patients with intoxication in four years were documented. 152 (10%) of them had a severe intoxication or lethal outcome. In women suicide predominated as reason of severe intoxication, whereas in men an abuse of alcool and drugs was mostly seen. A multidisciplinary approach is important for handling intoxicated patients. Our investigation showed a good somatical outcome of patients with severe intoxication. Mortality was 5% (7/152 patients).

Heavy alcohol consumption during young adulthood is a risk factor for the development of serious alcohol use disorders. Research has shown that individual differences in subjective responses to alcohol may affect individuals' vulnerability to developing alcoholism. Studies comparing the subjective and objective response to alcohol between light and heavy drinkers (HDs), however, have yielded inconsistent results, and neural responses to alcohol in these groups have not been characterized. We performed a double-blind, placebo-controlled, randomized crossover alcohol challenge study comparing functional magnetic resonance imaging and subjective response to intravenously administered 6% v/v ethanol to a target blood alcohol concentration of 0.08% or placebo between HDs and social drinkers (SDs). During the imaging, we presented emotional cues in order to measure how emotion modulated the effects of alcohol on the brain's reward circuitry. We found that, at equivalent blood alcohol concentrations, HDs reported lower subjective alcohol effects than SDs. Alcohol significantly activated the nucleus accumbens in SDs, but not in HDs. Self-reported ratings of intoxication correlated with striatal activation, suggesting that activation may reflect subjective experience of intoxication. Fearful faces significantly activated the amygdala in the SDs only, and this activation was attenuated by alcohol. This study shows that HDs not only experience reduced subjective effects of alcohol, but also demonstrate a blunted response to alcohol in the brain's reward system. Our findings indicate that reduced subjective and neural response to alcohol in HDs may be suggestive of either the development of tolerance to alcohol, or of pre-existing decreased sensitivity to alcohol's effects.

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

The low level of response (LR) to alcohol is a genetically influenced characteristic related to the development of alcohol use disorders (AUDs). This phenotype is found in men with a family history (FH) of alcoholism, predicts future AUDs, and has heritabilities as high as 60%. However, despite evidence of genetic influences for AUDs in both sexes, the majority of studies evaluating differences in LR across high- and low-risk groups have been conducted on males, and it is unclear how generalizable these results are to women. Twenty-five women who are family history positive (FHP) for alcohol dependence were matched with 25 women with no FH of alcoholism (FHN) on factors that may impact LR. Using an alcohol challenge paradigm, data on the reaction to a moderate dose of alcohol were gathered over a period of 3.5 h. Assessments included breath alcohol concentrations (BrACs), the Subjective High Assessment Scale (SHAS), as well as body sway or static ataxia. Family history positives reported lower subjective intoxication than FHNs. In addition, when body sway scores were corrected for skewness, FHPs had significantly lower scores on alcohol-related changes in lateral sway. These differences remained after considering the effects of drinking history and BrAC values. This study evaluated the LR to alcohol in the largest sample of alcohol challenges in matched FHP and FHN women to date. Overall, the findings are consistent with most data from earlier investigations of smaller sized samples of FHP women. The results suggest that, similar to sons of alcoholics, a low LR to alcohol might also be characteristic of daughters of alcoholics.
Full Text Available Colchicine is frequently used in the treatment of familial Mediterranean fever (FMF. First symptoms of colchicine intoxication are gastrointestinal disturbances, such as abdominal cramps, diarrhea, pancytopenia and so on. Herein, we report a female FMF patient with pancytopenia and hemophagocytic lymphohitiocytosis (HLH, following colchicine intoxication for committing suicide. To our knowledge, this is the first reported case of a patient with HLH associated with colchicine intoxication.
The defense of involuntary intoxication has long been an exception to the general notion that intoxication is not a defense to criminal liability. The consumption of medications prescribed by a physician can form the basis of an involuntary-intoxication defense. In this article, I review cases where defendants relied on the use of prescribed medications for an involuntary-intoxication defense. The medications most frequently implicated by defendants are listed by name and by class. From the case law, I provide a summary of the defense and a review of the pitfalls of the defense to serve as practice pointers for forensic evaluators. © 2015 American Academy of Psychiatry and the Law.

This study sought to clarify if Alexander the Great indulged pathologically in alcohol and whether it contributed to his death. The texts of the historians Diodorus of Sicily, Plutarch, Arrian, Curtius Rufus, Athenaeus, Aelian and Justin were studied, with their information concerning wine consumption by Macedonians, and especially Alexander, and were evaluated. The surviving historical texts, all later than Alexander's epoch, are based on a series of contemporary histories and especially on the 'Royal Journals', an official diary written in the imperial court. Alexander consumed large quantities of undiluted wine periodically, reaching pathological intoxication. However, the existing data do not provide convincing evidence that Alexander the Great manifested abuse of or dependence on alcohol according to DSM-IV or ICD-10 criteria and it seems unlikely that alcohol was involved in his untimely death.

The high suicide rate in Russia and its profound fluctuation over the past decades have attracted considerable interest. There is growing evidence that beverage preference and binge-drinking patterns, i.e., excessive consumption of strong spirits, results in a quicker and deeper level of intoxication, which increases the propensity for the alcohol-related suicide. In line with this evidence, we assumed that higher levels of vodka consumption, in conjunction with binge-drinking patterns, would result in a close, aggregate-level association between vodka sales and suicide in Russia. To test this hypothesis, trends in beverage-specific alcohol sales per capita and suicide rates from 1970 to 2005 in Russia were analyzed employing ARIMA time-series analysis. The results of the time-series analysis suggested that a 1 liter increase in overall alcohol sales would result in a 4% increase in the male suicide rate and a 2.8% increase in the female suicide rate; a 1 liter increase in vodka sales would increase the suicide rate by 9.3% for men and by 6% for women. This study replicates previous findings from other settings, which suggest that suicide rates tend to be more responsive to changes in distilled spirits consumption per capita than to the total level of alcohol consumption. Assuming that drinking spirits is usually associated with intoxication episodes, these findings provide additional evidence that the drinking pattern is an important determinant in the relationship between alcohol and suicide. The outcomes of this study also provide support for the hypothesis that suicide and alcohol are closely connected in cultures where an intoxication-oriented drinking pattern prevails and adds to the growing body of evidence that alcohol plays a crucial role in the fluctuation in suicide mortality rates in Russia during recent decades.

This experiment examined the effects of women's relationship motivation, partner familiarity, and alcohol consumption on sexual decision making. Women completed an individual difference measure of relationship motivation and then were randomly assigned to partner familiarity condition (low, high) and to alcohol consumption condition (high dose, low dose, no alcohol, placebo). Then women read and projected themselves into a scenario of a sexual encounter. Relationship motivation and partner familiarity interacted with intoxication to influence primary appraisals of relationship potential. Participants' primary and secondary relationship appraisals mediated the effects of women's relationship motivation, partner familiarity, and intoxication on condom negotiation, sexual decision abdication, and unprotected sex intentions. These findings support a cognitive mediation model of women's sexual decision making and identify how individual and situational factors interact to shape alcohol's influences on cognitive appraisals that lead to risky sexual decisions. This knowledge can inform empirically based risky sex interventions.

Background The primary goal of this study was to establish a paradigm for credibly administering placebo alcohol to underage drinkers. We also sought to create a new, valid procedure for establishing placebo alcohol believability. Method Participants were 138 American college students (66.7% female) predominantly (90.0%) under the legal drinking age. Groups of 2–3 participants and one same-sex confederate consumed mixed drinks, purportedly containing alcohol, ad-lib in a naturalistic bar-laboratory for 20 minutes. All beverages, however, were non-alcoholic but we used visual, olfactory, and taste cues to maximize placebo credibility. Also, the confederate made two scripted statements designed to increase the perception of drinking real alcohol. After the drinking portion, participants responded to survey items related to alcohol consumption and intoxication. Next, they were individually debriefed, with open-ended responses used to make a determination of whether the participant was deceived with respect to placebo alcohol. Results All participants estimated consuming some amount of alcohol. However, using a more conservative criteria for estimating alcohol believability based on the debrief, 89.1% of participants were classified as deceived. Deceived participants were much more likely to estimate having a positive Blood Alcohol Content, and to say their current level of intoxication was typical given the amount of alcohol consumed than non-deceived participants. Discussion Credibly administering placebo alcohol to underage drinkers is possible. This approach carries great potential for future laboratory work. In addition, the methodology used here to classify participants as deceived or not deceived appears valid based on self-reported BAC estimation and intoxication levels. PMID:26334562

Ethylene glycol (EG) and methanol poisoning can cause life-threatening complications. Toxicity of EG and methanol is related to the production of toxic metabolites by the enzyme alcohol dehydrogenase (ADH), which can lead to metabolic acidosis, renal failure (in EG poisoning), blindness (in methanol poisoning) and death. Therapy consists of general supportive care (e.g. intravenous fluids, correction of electrolytes and acidaemia), the use of antidotes and haemodialysis. Haemodialysis is considered a key element in the treatment of severe EG and methanol intoxication and is aimed at removing both the parent compound and its toxic metabolites, reducing the duration of antidotal treatment and shortening the hospital observation period. Currently, there are two antidotes used to block ADH-mediated metabolism of EG and methanol: ethanol and fomepizole. In this review, the advantages and disadvantages of both antidotes in terms of efficacy, safety and costs are discussed in order to help the physician to decide which antidote is appropriate in a specific clinical setting.

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

Consumption of alcohol mixed with energy drinks (AmED) has been associated with both short- and long-term risks beyond those observed with alcohol alone. AmED use has been associated with heavy episodic (binge) drinking, risky behaviors, and risk of alcohol dependence. Laboratory research has demonstrated that AmED beverages lead to greater motivation to drink versus the same amount of alcohol consumed alone. However, the reason consumers find AmED beverages particularly appealing has been unclear. A recent report by Droste and colleagues (Alcohol Clin Exp Res 2014; 38:2087-2095) is the first study to investigate motivations related to AmED consumption and to determine which motives predict AmED consumption patterns, experience of drinking-related harms, and risk of alcohol dependence. The findings of this study significantly enhance our understanding of why AmED consumption is related to the risk of alcohol dependence and change our understanding of why consumers choose AmED beverages. The authors report that hedonistic motives strongly predicted AmED use and the harms associated with use. While intoxication-reduction motives predicted self-reported accidents and injuries, these motives did not predict AmED consumption patterns and risk of dependence. The risk of alcohol dependence may arise from repeated experiences when drinking alcohol is more pleasurable when energy drinks are consumed with the alcohol. This commentary will focus on why energy drinks might increase the rewarding properties of alcohol in social drinkers. In addition, discussion is provided explaining why more research on the neurotransmitter, adenosine, may actually inform us about the mechanisms contributing to the development of alcohol dependence.

Full Text Available Chronic excessive alcohol intoxications evoke cumulative damage to tissues and organs. We examined prefrontal cortex (Brodmann's area (BA 9 from 20 human alcoholics and 20 age, gender, and postmortem delay matched control subjects. H & E staining and light microscopy of prefrontal cortex tissue revealed a reduction in the levels of cytoskeleton surrounding the nuclei of cortical and subcortical neurons, and a disruption of subcortical neuron patterning in alcoholic subjects. BA 9 tissue homogenisation and one dimensional polyacrylamide gel electrophoresis (PAGE proteomics of cytosolic proteins identified dramatic reductions in the protein levels of spectrin β II, and α- and β-tubulins in alcoholics, and these were validated and quantitated by Western blotting. We detected a significant increase in α-tubulin acetylation in alcoholics, a non-significant increase in isoaspartate protein damage, but a significant increase in protein isoaspartyl methyltransferase protein levels, the enzyme that triggers isoaspartate damage repair in vivo. There was also a significant reduction in proteasome activity in alcoholics. One dimensional PAGE of membrane-enriched fractions detected a reduction in β-spectrin protein levels, and a significant increase in transmembranous α3 (catalytic subunit of the Na+,K+-ATPase in alcoholic subjects. However, control subjects retained stable oligomeric forms of α-subunit that were diminished in alcoholics. In alcoholics, significant loss of cytosolic α- and β-tubulins were also seen in caudate nucleus, hippocampus and cerebellum, but to different levels, indicative of brain regional susceptibility to alcohol-related damage. Collectively, these protein changes provide a molecular basis for some of the neuronal and behavioural abnormalities attributed to alcoholics.

To report the periodontal status of older adults in Plateau State, Nigeria, and determine its Association with alcohol consumption. Periodontal disease is common among Nigerians, and the prevalence increases with age. The role that alcohol consumption plays in the occurrence of the disease among Africans is uncertain. Sample selection was performed using a multistage cluster sampling technique among older adults in Plateau State, Nigeria. Interviews, using structured questionnaires, were conducted for each of the participants. Clinical examinations were then carried out to determine the occurrence of periodontal disease, assessed by clinical attachment loss and probing depth. The prevalence of periodontal disease was 79%, being severe in 46% of the population. Almost half of the participants (46.7%) examined were still actively consuming alcohol, among which 48% reported a history of intoxication. There was no statistically significant relationship between periodontal disease and the frequency of alcohol consumption, or quantity consumed on each occasion. However, alcohol consumption was highly correlated with periodontal disease among those who reported intoxication from the drink (r = 0.095; p = 0.033). A history of intoxication with alcohol was the only significant predictor of periodontal disease, after adjusting for age and gender. Periodontal disease was highly prevalent among older Nigerians in this study. Apart from those who reported intoxication from alcohol, there was no statistically significant relationship between the prevalence of periodontal disease and the frequency of alcohol consumption or the quantity consumed on each occasion. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

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.

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)

Intoxications with gamma-hydroxybutyrate (GHB) are occurring more frequently. Patients are primarily treated symptomatically. The use of activated charcoal (AC) has been suggested in several guidelines and in literature, although the clinical value of AC in GHB intoxication is a matter of debate. However, it has never been demonstrated that GHB binds to AC. Under certain conditions, prevention of absorption could be clinically relevant. Therefore, adsorption of GHB to AC in an in vitro model was tested. A previously described in vitro model was used. Dosages of 2.5, 5, 7.5, or 10 g of standard AC (simulating in vivo dosages of approximately 25-100 g) were mixed with a dose of 800 mg GHB at 37 °C in 100 mL simulated gastric or intestinal fluid, respectively. Subsequently, the AC was separated from the liquid by centrifugation and the remaining GHB quantified by gas chromatography. GHB adsorption capacity was plotted in an adsorption curve. Binding of GHB to AC was dose-dependent. At gastric pH, adsorption was higher than at intestinal pH, with a maximum adsorption of 84.3% and 23.3%, respectively, with 10 g of AC, corresponding with a high adult dose. AC has clinically relevant GHB binding capacity, which is pH dependent. The normally rapid adsorption and the need for intubation argue against AC treatment in GHB intoxications. However, under certain circumstances e.g. in case of unintentional intake of GHB by children or in case of very high doses of GHB, rapid treatment with AC may still be appropriate. In vivo studies are needed to establish the clinical relevance of GHB adsorption to AC. Copyright © 2012 Elsevier B.V. All rights reserved.

Full Text Available Introduction: Conviction rates for drivers driving under the influence (DUI and in motor vehicle collisions (MVC presenting to trauma centers are based primarily on data from the 1990s. Our goal was to identify DUI conviction rates of intoxicated drivers in MVCs presenting to a trauma center and to identify factors associated with the failure to obtain a DUI conviction. Methods: Retrospective study of adults (>18 years presenting to a trauma center emergency department (ED in 2007. Eligible subjects were drivers involved in a MVC with an ED blood alcohol level (BAL ≥ 80mg/dL. Subjects were matched to their Department of Motor Vehicle (DMV records to identify DUI convictions from the collision, the legal blood alcohol concentration (BAC, and arresting officer’s impression of the driver’s sobriety. We entered potential variables predictive of failure to obtain a DUI conviction into a regression model. Results: The 241 included subjects had a mean age of 34.1 ± 12.8 years, and 185 (77% were male. Successful DUI convictions occurred in 142/241 (58.9%, 95% CI 52.4, 65.2% subjects. In a regression model, Injury Severity Score > 15 (odds ratio = 2.70 (95% CI 1.06, 6.85 and a lower ED BAL from 80 to 200mg/dL (odds ratio = 5.03 (95% CI 1.69, 14.9 were independently associated with a failure to obtain a DUI conviction. Conclusion: Slightly more than half of drivers who present to an ED after a MVC receive a DUI conviction. The most severely injured subjects and those with lower BALs are least likely to be convicted of a DUI.

Most research on drinking games (DGs) and the associated risks focuses on Western countries. In the Nigerian context, DGs activity has not attracted scholarly attention but growing media reports indicate that Nigerian youths play DGs, and that a number of gamers have died during or immediately after game-playing. Drawing on gender performance scripts, we explored the performance of gender through DGs practices and the factors that motivate DGs participation. Thirty-one in-depth interviews were conducted with male and female college students (aged 19-23 years) at a university in south-eastern Nigeria. The participants discussed the popularity of the DGs that students play on this campus, identifying the spaces where each game is played and the motivations for game-playing. Collective, contextual constructions of gender identities through 'Fastest-Drinker' DG were identified, and the participants also performed gender through 'Truth-or-Dare' and 'Endurance' DGs. Men dominated 'First-to-Finish' DGs, which are played at parties and bars, and consumed beer or stout, while women, who mainly played Truth-or-Dare games, drank spirits or sweetened alcoholic beverages. Boredom and fun seeking provoked game-playing among women while adherence to masculinity norms, which engendered the public performance of masculinity and gambling activities, motivated men to play DGs. To avoid 'collective shame', men's friendship groups provided support/care for inebriated game-playing members, but the immediacy of this support/care varied according to DGs type. DGs appear to normalize heavy drinking and the culture of intoxication on this campus. Measures to monitor alcohol sales outlets around campuses and interventions that target students' leisure spaces should be developed.

Methanol, ethylene glycol, diethylene glycol, and propylene glycol intoxications are associated with cellular dysfunction and an increased risk of death. Adverse effects can develop quickly; thus, there is a need for methods for rapidly detecting their presence. To examine the value and limitations of present methods to diagnose patients with possible toxic alcohol exposure. I searched MEDLINE for articles published between 1969 and 2014 using the terms: toxic alcohols, serum osmolality, serum osmol gap, serum anion gap, metabolic acidosis, methanol, ethylene glycol, diethylene glycol, propylene glycol, and fomepizole. Each article was reviewed for additional references. The diagnosis of toxic alcohol exposure is often made on the basis of this history and physical findings along with an increase in the serum osmol and anion gaps. However, an increase in the osmol and/or anion gaps is not always present. Definitive detection in blood requires gas or liquid chromatography, laborious and expensive procedures which are not always available. Newer methods including a qualitative colorimetric test for detection of all alcohols or enzymatic tests for a specific alcohol might allow for more rapid diagnosis. Exposure to toxic alcohols is associated with cellular dysfunction and increased risk of death. Treatment, if initiated early, can markedly improve outcome, but present methods of diagnosis including changes in serum osmol and anion gap, and use of gas or liquid chromatography have important limitations. Development of more rapid and effective tests for detection of these intoxications is essential for optimal care of patients.

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.

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

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.

This study was the first to test the moderating effect of acute alcohol intoxication on the relation between heterosexual men's sexual prejudice and perpetration of aggression toward gay men and lesbians. Participants were 320 heterosexual men aged 21-30 recruited from a large southeastern United States city. Participants completed a measure of prejudice toward sexual minorities and were randomly assigned to one of eight experimental groups within a 2 (Beverage: Alcohol, No-Alcohol Control) × 2 (Opponent Gender: Male, Female) × 2 (Opponent Sexual Orientation: Homosexual, Heterosexual) design. Following beverage consumption, participants were provoked via reception of electric shocks from a fictitious opponent. Participants' physical aggression was measured using a shock-based aggression task. The association between sexual prejudice and aggression toward the gay male opponent was stronger among intoxicated, relative to sober, participants. This pattern of association was not observed among participants who competed against the heterosexual male, heterosexual female, or lesbian opponent. Findings provide the first experimental evidence that alcohol intoxication moderates sexually-prejudiced aggression toward gay men. These data offer a first step toward understanding how alcohol facilitates bias-motivated aggression. Such knowledge contributes to the empirical foundation needed to guide the development of interventions for alcohol-related aggression toward sexual minorities.

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.

Ricinine is an alkaloid present in the castor bean plant (Ricinus communis) that can be used as a biomarker for ricin poisoning. Serial ricinine levels are reported in the serum and urine of a patient suffering from intentional ricin intoxication. The patient was brought to the hospital 4 h after injection and oral intake of a castor bean extract, but died 38 h later, despite intensive medical care. Ricinine was isolated from the samples by solid-phase extraction and quantitatively determined by isotopic dilution liquid chromatography-mass spectrometry. The ricinine level in serum declined from 33 to 23 ng/mL between 10 and 29 h post-exposure. Three urine samples collected from 12 to 41 h after ricin intoxication showed ricinine concentrations in the range of 20-58 ng/mL. The creatinine corrected values (21-30 µg/g) indicated a concentration-time profile with a maximum ricinine level in urine between 12 and 29 h after exposure.
Full Text Available Wild ruminants, including deer species (cervids have incorrectly been regarded as refractory to yew (Taxus intoxication. This assumption has been based upon anecdotal observations of individual deer browsing on yew over time without apparent adverse effect. A single case of yew intoxication was reported in a free-ranging Norwegian moose (Alces alces in 2008. The current report describes five additional cases of yew toxicosis in moose, seven in roe deer (Capreolus capreolus and two in reindeer (Rangifer tarandus tarandus, all in Norway. The animals were found dead during the winter, close to or within gardens containing yew plants showing signs of browsing. Gross findings included lung congestion and edema, thoracic and pericardial effusion, bilateral heart dilatation, epi- and endocardial hemorrhage, and enlarged (congested spleen. Yew plant remnants were detected in the rumen of all animals with the exception of a single moose. Histology revealed multifocal acute myocardial degeneration and necrosis with hemorrhage in roe deer, but not in the two other species. A qualitative high performance liquid chromatography-ion trap mass spectrometry analysis was used to tentatively identify five major Taxus alkaloids (taxines in crude yew extracts and in heart and liver samples from the moose cases. All five major taxines were detected with good signal/noise ratio in tissue samples from the four moose with visible ruminal yew content, whereas lower levels of taxines were detected in the moose without visible ruminal yew content. Possible differences in interspecies tolerance to taxines and role of individual protective adaptation are discussed.

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.

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.

Presently used methods for detection and diagnosis of the severity of intoxication with organophosphorus (OP) compounds are mostly those that quantify inhibition of blood cholinesterases. It was found that when plasma inhibited with OP compounds is incubated in the presence of a high concentration of fluoride ions, the organophosphate is released from the enzyme thus yielding a phosphofluoridate, which can be analyzed by gas chromatography and NP detection. In our study, the concentration of sarin released after fluoride ions were added to the plasma of sarin-poisoned rats was determined. Sarin amounts in plasma measured after refluoridation and plasma butyrylcholinesterase activity in ten rats, that were exposed to sarin vapors at concentration of 1.25 microg/L (E1 group) and 2.5 microg/L (E2 group) respectively, for 60 min. In the E2 group the concentration of sarin in plasma was nearly 2-fold higher than in the E1 group. These results correspond well with the concentrations of sarin vapors to which the animals were exposed. Both experimental groups of animals showed significant decreases in butyrylcholinesterase activity by more than 30%-36.4% (E1 group) and 47.0% (E2 group). The method of fluoride-induced reactivation provides a very good marker for monitoring sarin intoxication in laboratory animals determined previously mostly by ChE determination which does not allow any information on sarin amounts in plasma.

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

The numerous adverse effects of ethanol abuse and ethanol withdrawal on biological systems are well documented. Conversely, the understanding of the molecular mechanisms underlying these pathological effects is still incomplete. This study was undertaken to investigate the effects of short-term chronic ethanol administration and ethanol withdrawal on the molecular structure and function of hippocampal tissue, a brain region important for mnemonic processes and known to be highly susceptible to ethanol intoxication. Ethanol was administered to adult Wistar rats by intragastric intubation for 15 days with a stepwise increase in the daily dose from 6 to 12 g/kg body weight, with the highest dose delivered for the last 2 days only. The total daily dose of ethanol was divided into 3 equal portions administered 4 hours apart. Animals were sacrificed by decapitation at 4, 24, and 72 hours after the last ethanol administration to examine potential effects of ethanol intoxication and ethanol withdrawal. Ethanol-related molecular changes were monitored by Fourier transform infrared (FT-IR) spectroscopy. Significant changes in the hippocampal content, structure, and function of lipids, proteins, and nucleic acids were recorded under ethanol intoxication. Seventy-two hours after the cessation of ethanol administration, during the late phase of withdrawal, alterations in the macromolecules' content and conformational changes in protein and nucleic acid structure ameliorated, while the changes in macromolecular ratios, lipid order, and dynamics aggravated. Our results suggest that 15 days of binge-like drinking resulting in the high blood alcohol concentration (varying in the dose-dependent manner between 253 and 606 mg/dl) produced a strong physical dependence manifested mainly by the changes in lipid profiles pointing toward withdrawal-induced oxidative stress. These results show that ethanol withdrawal may cause equal to or even more severe brain damage than the ethanol

The aim of the study was to analyze independent and potential interactive effects of age at drinking onset and family history of alcohol abuse on subsequent patterns of alcohol drinking, alcohol-related problems and substance use. Participants were college students (60.3% females, mean age = 20.27 ± 2.54 years) from the city of Córdoba, Argentina. Several measures were used to assess alcohol, tobacco and drug use. The Spanish version of the Brief Young Adult Alcohol Consequences Questionnaire was used to assess alcohol-related problems. Factorial analyses of variance, or its non-parametric equivalent, were performed to explore differences in substance use behaviors and alcohol-related problems in subjects with early or late drinking onset and with or without family history of alcohol abuse. Chi-square tests were conducted to analyze the association between these two risk factors and categorical measures of alcohol, tobacco and drug use. Early onset of drinking was associated with amount of consumption of alcohol including up to hazardous levels, as well as tobacco and drug use. However, the frequency of alcohol problems and frequency of episodes of alcohol intoxication were only related to age of onset in those with a positive family history of alcohol problems. Delaying drinking debut is particularly important in the prevention of future alcohol problems in those adolescents who have a family history of such problems.

The ingestion of toxic alcohols, specifically ethylene glycol (EG) and methanol, provides unique therapeutic challenges for emergency personnel. If untreated, these agents can result in significant morbidity and mortality. The toxicity of EG and methanol is dependent on endogenous metabolic processes rather than the actual parent compound ingested. These metabolites lead to the characteristic metabolic acidosis and cellular dysfunction typically seen with toxic alcohol ingestions. Fortunately, several options exist for the treatment of these ingestions, which, if implemented in the appropriate time period, can significantly decrease associated morbidity and mortality. The intent of this review is to discuss relevant management issues associated with EG and methanol intoxication in the emergency department.

Coconsumption of alcohol with energy drinks (AED) is becoming increasingly popular among adolescents and young adults and has been associated with a range of harms. Motivations related to determined drunkenness and hedonistic drinking are potentially important in explaining both alcohol and AED consumption, given that a relationship has been identified between AED use and heavy alcohol consumption. This study aimed to explore motives for combined AED consumption, as well as their relationship with alcohol dependence and experiences of harm and aggression. Students (n = 594) enrolled at Deakin University, Victoria, Australia, completed an anonymous online survey in 2012. Approximately two-thirds of the sample (66.5%) were female, and the mean age was 22.3 (SD = 4.5), consistent with 2012 Deakin University enrollment. Principal axis factor analysis of 14 items measuring motivations for AED use identified 4 factors, categorized as "hedonistic," "social," "energy/endurance," and "intoxication-reduction" motives. Multinomial and binary logistic regression analyses demonstrated that hedonistic motives for AED use significantly predicted increases in alcohol and energy drink coconsumption during AED episodes, risk of alcohol dependence, as well as experiencing harm and aggression. Intoxication-reduction motives significantly predicted harm outcomes. Hedonistic motives specific to sensation and pleasure ideals are implicated in negative consequences associated with coconsumption of alcohol and energy drinks. Further, consumers who reported using AEDs to reduce alcohol intoxication were at increased risk of negative outcomes, a finding indicating that consumer knowledge of the effects of AED use may be limited.

Little is known about social-ecological correlates of simultaneous use of alcohol with other substances. This study examined places and social contexts associated with simultaneous use of alcohol, tobacco and marijuana among young adults. We used survey data obtained from 1538 young adult recent alcohol drinkers (49% male; 18-30 years old) in 24 non-contiguous cities in California. Event-level measures included alcohol, tobacco and marijuana use, drinking places and social characteristics of the event. Individual-level measures included alcohol expectancies, depression and demographics. Bars and restaurants had less alcohol and marijuana use (odds ratio = 0.34; 95% confidence interval 0.18, 0.62; P < 0.001) and alcohol, marijuana and tobacco use (odds ratio = 0.27; 95% confidence interval 0.14, 0.54; P < 0.001) compared with alcohol use only. Perceived percent of intoxicated people at an event was associated with greater likelihood of using alcohol with tobacco and marijuana at the event. At the individual level, greater age was generally associated with increased odds of simultaneous use. Participants who were male, less educated, more depressed and had positive alcohol expectancies were more likely to simultaneously co-use alcohol with tobacco and marijuana. Those with negative expectancies were less likely to simultaneously use these substances. Social events in private settings with a high percentage of people who are intoxicated had increased likelihood of simultaneous use of alcohol, tobacco and marijuana. Prevention efforts in these settings may reduce simultaneous use of these substances and related harms. [Lipperman-Kreda S, Paschall MJ, Saltz RF, Morrison CN.

Full Text Available The association between substance use and criminality can be deduced from the acknowledgment of the increase of what are commonly called drug-defined offences, and those offences committed while under the influence of drug and/or alcohol. The aim of this study was to determine the prevalence of substance use disorder, the relationship between type of crime and demographic profile, and the relationship between offence committed and degree of intoxication with alcohol and illegal drugs at the time of crime among convicted and awaiting trial violent offenders. A cross-sectional descriptive study was carried out among 432 male inmates either convicted or awaiting trial in Jos maximum security prison, Plateau state. They completed a pro forma questionnaire containing their demographic and forensic profiles. They were screened with self-administered General Health Questionnaire item 28 and interviewed with the Composite International Diagnostic Interview questionnaire. The prevalence of substance use disorder was 54% (233. A significant correlation was found between type of offence committed and intoxication with substance at the time of crime (odds ratio = 0.3003; P= 0.001. High prevalence of substance use disorder was found among violent offenders in the prison.

Background and aims Although alcohol intake and gambling often co-occur in related venues, there is conflicting evidence regarding the effects of alcohol expectancy and intake on gambling behavior. We therefore conducted an experimental investigation of the effects of alcohol expectancy and intake on slot machine gambling behavior. Methods Participants were 184 (females = 94) individuals [age range: 18-40 (mean = 21.9) years] randomized to four independent conditions differing in information/expectancy about beverage (told they received either alcohol or placebo) and beverage intake [actually ingesting low (target blood alcohol concentration [BAC] 0.40 mg/L; ≈0.80 mg/L) amounts of alcohol]. All participants completed self-report questionnaires assessing demographic variables, subjective intoxication, alcohol effects (stimulant and sedative), and gambling factors (behavior and problems, evaluation, and beliefs). Participants also gambled on a simulated slot machine. Results A significant main effect of beverage intake on subjective intoxication and alcohol effects was detected as expected. No significant main or interaction effects were detected for number of gambling sessions, bet size and variation, remaining credits at termination, reaction time, and game evaluation. Conclusion Alcohol expectancy and intake do not affect gambling persistence, dissipation of funds, reaction time, or gambling enjoyment.

Community sports clubs provide an important contribution to the health and wellbeing of individuals and the community; however, they have also been associated with risky alcohol consumption. This study assessed whether a club's alcohol management strategies were related to risky alcohol consumption by members and levels of social capital, as measured in terms of participation in and perceived safety of the club. A total of 723 sports club members from 33 community football clubs in New South Wales, Australia, completed a computer assisted telephone interview (CATI) and a management representative from each club also completed a CATI. The club representative reported on the club's implementation of 11 alcohol management practices, while club members reported their alcohol consumption and perceived levels of safety at the club and participation in the club. A structural equation model identified having the bar open for more than four hours; having alcohol promotions; and serving intoxicated patrons were associated with increased risky alcohol consumption while at the club; which in turn was associated with lower levels of perceived club safety and member participation. The positive contribution of community sports clubs to the community may be diminished by specific inadequate alcohol management practices. Changing alcohol management practices can reduce alcohol consumption, and possibly increase perceived aspects of social capital, such as safety and participation. © 2014 Public Health Association of Australia.

Excessive alcohol consumption leads to neurodegeneration, which contributes to cognitive decline that is associated with alcohol use disorders (AUDs). The endocannabinoid system has been implicated in the development of AUDs, but little is known about how the neurotoxic effects of alcohol impact the endocannabinoid system. Therefore, the current study investigated the effects of neurotoxic, binge-like alcohol exposure on components of the endocannabinoid system and related N-acylethanolamines (NAEs), and then evaluated the efficacy of fatty acid amide hydrolase (FAAH) inhibition on attenuating alcohol-induced neurodegeneration. Male rats were administered alcohol according to a binge model, which resulted in a transient decrease in [³H]-CP-55,940 binding in the entorhinal cortex and hippocampus following two days, but not four days, of treatment. Furthermore, binge alcohol treatment did not change the tissue content of the three NAEs quantified, including the endocannabinoid and anandamide. In a separate study, the FAAH inhibitor, URB597 was administered to rats during alcohol treatment and neuroprotection was assessed by FluoroJade B (FJB) staining. The administration of URB597 during binge treatment did not significantly reduce FJB+ cells in the entorhinal cortex or hippocampus, however, a follow up "target engagement" study found that NAE augmentation by URB597 was impaired in alcohol intoxicated rats. Thus, potential alcohol induced alterations in URB597 pharmacodynamics may have contributed to the lack of neuroprotection by FAAH inhibition.

Five percent of alcoholics develop an acute pancreatitis (AP). The mechanism leading to pancreatic injury is not yet understood. Microcirculatory disorders seem to play a pivotal role. The objective of this study was to compare alcoholic pancreatic injury in response to intravenous and intragastric routes of alcohol administration. Alcohol was applied in rats intravenously (IV) or gastric via a surgical implanted feeding tube (IG). Serum alcohol concentration was maintained between 1.5‰ and 2.5‰. Four subgroups (n = 6/group) were examined in the IV/IG arm and compared with healthy controls. Pancreatic microcirculation, enzyme levels, and morphological damage were assessed after 3, 6, 12, and 24 hours. Microcirculatory analysis showed significantly disturbed pancreatic perfusion and increased adherent leukocytes in IV and IG animals. In IV and IG groups, serum amylase was increased without morphological signs of AP compared with healthy controls. Alcohol application does not induce AP in rodents, but impairs pancreatic microcirculation irrespectively of the application route. Intravenous application is commonly used and shows no disadvantages compared with the physiological intragastric application form. Therefore, the intravenous route offers a valid model, which mimics the physiological process for further studies of the influence of acute alcohol intoxication on the pancreas.

This study investigated how different doses of alcohol affected eyewitness recall. Participants (N = 126) were randomly assigned to three groups with different blood alcohol concentration (BAC), either a control group (mean BAC 0.00%, N = 42), a lower alcohol dose group (mean BAC 0.04%, N = 40), or a higher alcohol dose group (mean BAC 0.06%, N = 44). After consumption, participants witnessed a movie of a mock crime and were interviewed one week later. The main results showed that witnesses with the higher intoxication level recalled fewer details compared to witnesses with the lower intoxication level. The amount of alcohol consumed did not have an impact on the accuracy rate. No sex differences were found. The results are discussed in the light of past research. We conclude that more studies are needed before recommendations can be made to an applied setting. © 2013 The Authors.

Consumption of alcohol mixed with energy drinks (AmED) has been associated with both short and long-term risks beyond those observed with alcohol alone. AmED use has been associated with heavy episodic (binge) drinking, risky behaviors, and risk of alcohol dependence. Laboratory research has demonstrated that AmED beverages lead to greater motivation to drink versus the same amount of alcohol consumed alone. However, the reason consumers find AmED beverages particularly appealing has been unclear. A recent report by Droste and colleagues (2014) is the first study to investigate motivations related to AmED consumption and to determine which motives predict AmED consumption patterns, experience of drinking-related harms, and risk of alcohol dependence. The findings of this study significantly enhance our understanding of why AmED consumption is related to the risk of alcohol dependence and change our understanding of why consumers chose AmED beverages. The authors report that hedonistic motives strongly predicted AmED use and the harms associated with use. While intoxication-reduction motives predicted self-reported accidents and injuries, these motives did not predict AmED consumption patterns and risk of dependence. The risk of alcohol dependence may arise from repeated experiences when drinking alcohol is more pleasurable when energy drinks are consumed with the alcohol. This commentary will focus on why energy drinks might increase the rewarding properties of alcohol in social drinkers. In addition, discussion is provided explaining why more research on the neurotransmitter, adenosine, may actually inform us about the mechanisms contributing to the development of alcohol dependence.

Alcoholism is a complex disorder that demonstrates genetic heterogeneity. Genetic linkage studies of alcohol dependence also suffer from the probability that many individuals who inherit an enhanced risk never develop the clinical syndrome. Thus, studies of genetic influences in alcohol abuse or dependence would benefit from the identification of characteristics of an individual that are associated with the probability of developing the disorder. A reduced responsivity to alcohol has been reported to characterize almost 40% of sons of alcoholics and to predict future alcohol abuse or dependence a decade later. This study explores the existence of this characteristic in a more heterogeneous sample that is part of a genetic pedigree study of families of alcoholics. Eighteen to 30 year old subjects who were sons of alcohol dependent fathers and who were drinkers but not alcohol dependent were selected from pedigrees of alcoholics at all six sites of the Collaborative Study on the Genetics of Alcoholism (COGA) study. Family history negative controls matched on demography and substance use histories were selected for each subject. Data were obtained on 20 pairs of high-risk and low-risk men (40 subjects) following a challenge with 0.72 g/kg (0.9 ml/kg) of ethanol. Evaluations included measures of subjective feelings of intoxication and body sway, and changes in cortisol, ACTH and prolactin. The data corroborate a lower level of intensity of response to alcohol in the sons of alcoholics especially as measured by changes in cortisol, with similar but less robust changes in subjective feelings and other measures. The results expand upon earlier studies by using a more heterogeneous population of men at high alcoholism risk. The data highlight the possible usefulness of the reduced response to alcohol as an adjunct to future linkage analyses.

Some salivary markers of alcohol abuse/dependence have been proposed so far: aminotransferases, gamma-glutamyltransferase, ethanol, ethyl glucuronide, ethyl sulfate, sialic acid, β-hexosaminidase A, oral peroxidase, methanol, diethylene/ethylene glycol, α-amylase, clusterin, haptoglobin, heavy/light chains of immunoglobulins and transferrin. To investigate the effect of chronic alcohol drinking and smoking on the activity (pKat/ml) and output (pKat/min) of salivary lysosomal exoglycosidases: α-fucosidase (FUC), α-mannosidase (MAN), β-galactosidase (GAL), and β-glucuronidase (GLU), and their applicability as markers of alcohol dependence. The activity of FUC, MAN, GAL and GLU was measured colorimetrically in the saliva of healthy social drinkers, alcohol-dependent non-smokers and alcohol-dependent smokers. We observed an increased salivary activity of FUC, GAL, GLU and MAN, as well as an increased output of GAL and GLU, in comparison with controls. The highest increase in the activity/output was found in salivary GLU and MAN (GLU, even 7- to 18-fold), and the least in GAL. We found an excellent sensitivity and specificity and a high accuracy (measured by the area under the ROC curve) for salivary FUC, GLU and MAN activities. The salivary GLU activity positively correlated with the number of days of last alcohol intoxication. Salivary activity of FUC, GAL and MAN, but not GLU, positively correlated with the periodontal parameters such as gingival index and papilla bleeding index. Although we found an excellent sensitivity and specificity as well as a high accuracy for the salivary activity of FUC, GLU and MAN, the GLU activity seems to be mostly applicable as a marker of chronic alcohol drinking (alcohol dependence). © The Author 2014.

There is little research describing how intoxication levels change throughout the night in entertainment districts. This research aims to describe levels of alcohol intoxication across multiple Australian metropolitan and regional nightlife districts. This study was conducted in the night-time entertainment districts of three metropolitan cities (Sydney, Melbourne and Perth) and two regional cities (Wollongong and Geelong) in Australia. Data collection occurred approximately fortnightly in each city on a Friday or Saturday night between 8 pm and 5 am. Brief structured interviews (3-10 min) and breathalyser tests were undertaken in busy thoroughfares over six months. Of the 7037 individuals approached to participate in the study, 6998 [61.8% male, mean age 24.89 years (standard deviation 6.37; range 18-73)] agreed to be interviewed. There was a linear increase in blood alcohol concentration (BAC) levels throughout the night. Post hoc testing revealed significantly more highly intoxicated participants (i.e. BAC above 0.10 mg of alcohol per 100 mL of blood) after midnight (P gender differences disappeared by 3 am. There was no age differences in intoxication earlier in the night, but after midnight, patrons over the age of 21 showed increasing BAC levels. There is a consistent trend across the cities of high to very high levels of intoxication later in the night, with trends after midnight being significantly different to those before. © 2014 Australasian Professional Society on Alcohol and other Drugs.

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.

Cognitive and emotional disorders have been reported in veterans intoxicated with sulfur mustard (SM) a chemical weapon belonging to the category of vesicating agents. However, the intense stress associated with the SM intoxication may render difficult determining the exact role played by SM intoxication itself on the emergence and maintaining of cognitive disorders. Animal's model would allow overcoming this issue. So far, we presently investigated the cognitive and emotional impact of an acute cutaneous intoxication with CEES (2-chloroethyl ethyl sulfide), a SM analog in C57/Bl6 mice. Our study evidenced that up to 5days after a single acute neat CEES skin exposure, compared to controls, mice exhibited i) a significant increase in anxiety-like reactivity in an elevated plus-maze and in an open-field tasks and ii) an alteration of working memory in a sequential alternation task. In contrast, mice submitted to intoxication with a diluted CEES solution or hydrochloric acid (HCl) did not show any memory or emotional impairments. Given that, Our data shows that a single local cutaneous intoxication with neat CEES induced long-lasting cognitive and emotional pejorative effects, in accordance with the epidemiological observations in veterans. Thus, the single acute neat CEES cutaneous intoxication in mice could allow studying the sulfur mustard-induced cognitive and emotional disorders and their further counter-measures.

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.
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.
When a patient operates a vehicle, he commits a traffic violation if he is incapable of conducting his vehicle safely in traffic at that time. If the lack of safety has been caused by medication or other types of intoxicating drugs, he commits a criminal offense. At present, scientific evidence suggests that the proof of a causal link between driving insecurities and the intake of intoxicating medication cannot solely be based upon the quality and quantity of such medication but must also take into account the possible establishment of visible physical disabilities.A physician must thoroughly inform his patient of all relevant risks both of the illness itself and its medical treatment in relation to traffic safety. The former is nevertheless not legally authorized to suspend the patient's driving licence; neither does his explicit permission to operate a vehicle generally protect the patient from criminal prosecution. Even in cases where the capability to operate a vehicle is not subject to medical doubts, a patient should be encouraged to constantly scrutinize this capability, especially in regard to unexpected side-effects of the medication. Insufficient medical advice may result in criminal responsibility of the physician if an accident is proved to have been caused by the patient, resulting in injury of the patient or a third party. If sufficient advice has been conveyed, possible criminal responsibility is limited to cases where the patient lacks the ability to act self-responsibly or if there is the imminent danger of an accident. If the physician learns that a patient with relevant disabilities will attempt to conduct a vehicle despite his opposite advice, he may inform the traffic authority after having repeatedly and unsuccessfully communicated with the patient and after having carefully balanced the interests of the parties involved. The physician is then longer obliged to abide by the requirement of medical confidentiality; there is, however, no legal

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.

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

Variability in sensitivity to the acute effects of alcohol is an important risk factor for the development of alcohol use disorder (AUD). The most commonly used retrospective self-report measure of sensitivity, the Self-Rating of the Effects of Alcohol (SRE) form, queries a limited number of alcohol effects and relies on respondents' ability to recall experiences that might have occurred in the distant past. Here, we investigated the construct validity of an alternative measure that queries a larger number of alcohol effects, the Alcohol Sensitivity Questionnaire (ASQ), and compared it to the SRE in predicting momentary subjective responses to an acute dose of alcohol. Healthy young adults (N = 423) completed the SRE and the ASQ and then were randomly assigned to consume either alcohol or a placebo beverage (between-subjects manipulation). Stimulation and sedation (Biphasic Alcohol Effects Scale) and subjective intoxication were measured multiple times after drinking. Hierarchical linear models showed that the ASQ reliably predicted each of these outcomes following alcohol but not placebo consumption, provided unique prediction beyond that associated with differences in recent alcohol involvement, and was preferred over the SRE (in terms of model fit) in direct model comparisons of stimulation and sedation. The ASQ compared favorably with the better-known SRE in predicting increased stimulation and reduced sedation following an acute alcohol challenge. The ASQ appears to be a valid self-report measure of alcohol sensitivity and therefore holds promise for identifying individuals at-risk for AUD and related problems.

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...... 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....

Energy drinks are popular beverages that typically include high levels of caffeine and other ingredients such as taurine, or caffeine-containing herbs, such as guarana. While energy drinks are often consumed alone, they are also frequently used as mixers for alcoholic beverages. This review summarizes what is known about the scope of use of alcohol mixed with energy drinks, the risks associated with such mixtures, and the objective laboratory data examining how the effects of their consumption differ from consuming alcohol alone. The weight of the evidence reveals that consuming alcohol mixed with energy drinks is riskier than consuming alcohol alone and constitutes a public health concern. Consumption of these mixed beverages is frequent, especially in young and underage drinkers, and compared with alcohol alone, their use is associated with elevated rates of binge drinking, impaired driving, risky sexual behavior, and risk of alcohol dependence. Laboratory research (human and animal) has demonstrated that consuming alcohol mixed with energy drinks leads to altered subjective states including decreased perceived intoxication, enhanced stimulation, and increased desire to drink/increased drinking compared to consuming alcohol alone. Possible underlying mechanisms explaining these observations are highlighted in this review. © 2014 International Life Sciences Institute.

This article summarizes the proceedings of a symposium held at the conference on “Alcoholism and Stress: A Framework for Future Treatment Strategies” in Volterra, Italy, May 6–9, 2008. Chaired by Markus Heilig and Roberto Ciccocioppo, this symposium offered a forum for the presentation of recent data linking neuropetidergic neurotransmission to the regulation of different alcohol related behaviours in animals and in humans. Dr. Donald Gehlert described the development of a new corticotrophin releasing factor (CRH) receptor 1 antagonist and showed its efficacy in reducing alcohol consumption and stress-induced relapse in different animal models of alcohol abuse. Dr. Andrey Ryabinin reviewed recent findings in his laboratory indicating a role of the urocortin 1 (Ucn) receptor system in the regulation of alcohol intake. Dr. Annika Thorsell showed data supporting the significance of the neuropetide Y (NPY) receptor system in the modulation of behaviours associated with a history of ethanol intoxication. Dr. Roberto Ciccocioppo focused his presentation on the nociceptin/orphanin FQ (N/OFQ) receptors as treatment targets for alcoholism. Finally, Dr. Markus Heilig showed recent preclinical and clinical evidence suggesting that neurokinin 1 (NK1) antagonism may represent a promising new treatment for alcoholism. Collectively, these investigators highlighted the significance of neuropeptidergic neurotransmission in the regulation of neurobiological mechanisms of alcohol addiction. Data also revealed the importance of these systems as treatment targets for the development of new medication for alcoholism. PMID:19913192

Ethyl alcohol is the most commonly used psychoactive agent. It's average consumption in Poland totaled 9.67 liters per capita in 2013. Ethanol's biotransformation rate in an adult ranges from 7 to 10 grams per hour. The basic metabolism takes place in the liver through the oxidation involving NAD+. The alcohol is transformed first into acetaldehyde and then into acetic acid. In higher blood concentrations or in alcoholism, cytochrome's P-450 coenzyme CYP2E1 also plays an important role in this process. Alcohol is responsible for nearly 50% of annual deaths, mostly caused by an accident due to alcohol intoxication while driving. Studies were performed to determine the influence ethanol has on the human body and how it impacts the progression of illnesses such as senile dementia, cardiovascular diseases or osteoporosis. Scientists' attention was drawn to the possibility of ethyl alcohol's usage resulting in a reduction in an overall mortality rate, however the beneficial effects were observed only during a slight and moderate consumption. Higher doses of alcohol were associated with a decline in patient's condition. The purpose of this dissertation is an attempt to answer the question, whether the alcohol can be beneficial to the user's health and if so, in what doses? The importance of this topic comes from the fact that due to the alcohol being widely available, determining the influence it has on human body is vital for public health. Original articles and reviews were used to summarize the results of studies regarding the topic. © 2015 MEDPRESS.

Individuals involved in the treatment of alcoholism for decades have argued that men and women crave alcohol essentially because they enjoy the effect it offers. This effect is so mysterious that, while adults will confess that these cravings are potential dangerous to their health and well being, during consumption their reasoning and belief of these facts will alternate between the true and the false. In essence these individuals alcohol cravings life actually seems to them the only normal ...

To examine the effect of previous-day excessive alcohol consumption on laparoscopic surgical performance. Study 1 was a randomized controlled trial. Study 2 was a cohort study. Surgical skills laboratory. Sixteen science students (laparoscopic novices) participated in study 1. Eight laparoscopic experts participated in study 2. All participants were trained on the Minimally Invasive Surgical Trainer Virtual Reality (MIST-VR). The participants in study 1 were randomized to either abstain from alcohol or consume alcohol until intoxicated. All study 2 subjects freely consumed alcohol until intoxicated. Subjects were assessed the following day at 9 am, 1 pm, and 4 pm on MIST-VR tasks. Assessment measures included time, economy of diathermy use, and error scores. In study 1, both groups performed similarly at baseline, but the alcohol group showed deterioration on all performance measures after alcohol consumption. Overall, although the time score differences between the 2 groups were not statistically significant (P = .29), there was a significant difference between the 2 groups' diathermy (P < .03) and error (P < .003) scores. There was also a significant effect for time of testing (P < .003), diathermy (P < .001), and errors (P < .001). In study 2, experts demonstrated a similar postalcohol performance decrement for time (P < .02), diathermy (P < .001), and error scores (P < .001). Excessive consumption of alcohol appeared to degrade surgical performance the following day even at 4 pm, suggesting the need to define recommendations regarding alcohol consumption the night before assuming clinical surgical responsibilities.
Full Text Available Using plants in treating some diseases has become a tradition, ‘the nature’s pharmacy’ being an important source of therapy. At present, the medicinal plants properties are being re-assessed due to progress made in chemical, pharmaceutical and clinical research of plants and due to forms obtained from vegetal products, but especially due to the advantages they offer. In the context of more frequent use of natural products with pharmaceutical and therapeutical aims, both at a national and at an international level, our research hints at highlighting and giving details about a series of effects produced by vegetal extracts of Aronia melanocarpa and Silybum marianum on certain physiological, biochemical and histopathological processes at CD1 mice. In this study, 2 hydro-alcoholic extracts obtained from 2 species of medicinal plants (Aronia melanocarpa and Silybum marianum, were tested in order to analyse the hypoglycemiant activity. The data accumulated in the specialty literature reveal that the phytotherapeutic use of extracts of Aronia melanocarpa and Silybum marianum is based only on the major pharmacologic effect while the intimate action mechanism of the two vegetal products, al cellular and subcellular level, is not known. Starting from these premises, we considered useful the initiation of a comparative study regarding the antidiabetic influence of fluid extracts of Aronia melanocarpa and Silybum marianum upon mice experimentally intoxicated with alloxan monohydrate solution. CDI mice were used as an experimental model in order to induce diabetes: alloxan monohydrate was injected intraperitoneal with concentration of 130 mg/kg body (Ahmed Saber Abu – zaiton, 2013, dissolved in physiological serum, during two weeks, at an interval of 3 days. Both extracts acted positively by lowering blood sugar and by returning to normal body weight in diabetic mice. Aronia extract has a pronounced effect compared to milk thistle extract for both

While persons at risk for alcohol dependence by virtue of heavy drinking patterns or family history (FH) of alcohol use disorders have exhibited differential alcohol responses on a variety of measures, few studies have examined alcohol's effects on eye movements in these subgroups. The purpose of this study was to (1) conduct a placebo-controlled, dose-ranging study of alcohol's effects on eye movements and (2) examine the impact of these risk factors on oculomotor response to alcohol. A within-subject, double-blind laboratory study was conducted in N = 138 heavy (HD; n = 78) and light social drinkers (LD; n = 60) with self-reported positive (FH+) or negative (FH-) family history. Subjects participated in three laboratory sessions in which they consumed a beverage containing a high (0.8 g/kg) or low (0.4 g/kg) dose of alcohol or placebo. Smooth pursuit, pro-saccadic, and anti-saccadic eye movements were recorded before and at two intervals after alcohol consumption. Alcohol significantly impaired smooth pursuit gain and pro- and anti-saccade latency, velocity, and accuracy in a dose and time specific matter. HD and LD showed similar impairment on smooth pursuit gain and anti-saccade measures, but HD were less impaired in pro-saccade latency, velocity, and accuracy. FH+ and FH- subjects were equally impaired in nearly all pro- and anti-saccade measures, but FH+ were less impaired in smooth pursuit gain. In sum, alcohol produced systematic impairment on oculomotor functioning, even at a non-intoxicating dose. Furthermore, high- and low-risk drinkers may be vulnerable to select performance deficits relative to eye movement task.

Alcohol use and abuse are a problem on college campuses. Religious behaviors (religious attendance, prayer, and importance) have been shown to be a protective factor against alcohol use among college students. This study examined the role religious behaviors and positive and negative affect had on drinking (alcohol use and alcohol to intoxication). College students (765) completed an online survey. The results showed that college students who attended religious services were less likely to use alcohol than those who did not attend religious services. The results have important implications for college administrators and policy makers. Limitations and future research will be discussed.

As executive dysfunctions frequently accompany alcohol dependence, we suggest that reports of executive dysfunction in alcoholics are actually due, in some case to a maternal history of alcohol misuse (MHA+). A history of maternal alcohol dependence increases the risk for prenatal alcohol exposure to unborn children. These exposures likely contribute to executive dysfunction in adult alcoholics. To assess this problem, we propose a case-comparison study of alcohol-dependent subjects with and without a MHA. Ten alcohol-dependent subjects, with a maternal history of alcoholism (MHA) and paternal history of alcoholism (PHA), were matched with 10 alcohol-dependent people with only a paternal history of alcoholism (PHA). Executive functions (cancellation, Stroop, and trail-making A and B tests) and the presence of a history of three mental disorders (attention deficit hyperactivity disorder, violent behavior while intoxicated, and suicidal behavior) were evaluated in both populations. Alcohol-dependent subjects with MHA showed a significant alteration in executive functions and significantly more disorders related to these functions than PHA subjects. The major measures of executive functioning deficit are duration on task accomplishment in all tests. Rates of ADHD and suicidality were found to be higher in MHA patients compared to the controls. A history of MHA, because of the high risk of PAE (in spite of the potential confounding factors such as environment) must be scrupulously documented when evaluating mental and cognitive disorders in a general population of alcoholics to ensure a better identification of these disorders. It would be helpful to replicate the study with more subjects.

Full Text Available Alcohol has a wide variety of effects on physiology and behavior. One of the most well-recognized behavioral effects is disinhibition, where behaviors that are normally suppressed are displayed following intoxication. A large body of evidence has shown that alcohol-induced disinhibition in humans affects attention, verbal, sexual, and locomotor behaviors. Similar behavioral disinhibition is also seen in many animal models of ethanol response, from invertebrates to mammals and primates. Here we describe several examples of disinhibition in the nematode C. elegans. The nematode displays distinct behavioral states associated with locomotion (crawling on land and swimming in water that are mediated by dopamine. On land, animals crawl and feed freely, but these behaviors are inhibited in water. We found that additional behaviors, including a variety of escape responses are also inhibited in water. Whereas alcohol non-specifically impaired locomotion, feeding, and escape responses in worms on land, alcohol specifically disinhibited these behaviors in worms immersed in water. Loss of dopamine signaling relieved disinhibition of feeding behavior, while loss of the D1-like dopamine receptor DOP-4 impaired the ethanol-induced disinhibition of crawling. The powerful genetics and simple nervous system of C. elegans may help uncover conserved molecular mechanisms that underlie alcohol-induced disinhibition of behaviors in higher animals.

Alcohol and other recreational drug use reaches peak prevalence in young adulthood, including for those with chronic medical conditions such as type 1 diabetes. This review summarises the current literature on the patterns of substance use amongst young adults with type 1 diabetes and the mechanisms through which alcohol and recreational drugs may affect diabetes related health outcomes. These include the direct physical effect of intoxication, as well as the effects of alcohol and drugs on mental health and glucose metabolism. Evidence for increased associated mortality and morbidity is also presented, and current guidelines, management strategies and directions for further research are discussed.

In response to concern about whether mixing caffeinated energy drinks with alcohol (AED) increases alcohol consumption and related harm, and the role of industry in this debate, we conducted a comprehensive review of the research evidence on the effects of AED and documented industry involvement in this research. A systematic review of 6 databases. Studies must have examined the effect of consuming alcohol with energy drinks (ED) or caffeine on alcohol-related outcomes. 62 studies were identified; 29 were experiments, 9 had industry ties (8 with Red Bull GmbH). Young adults who consumed AED drank more alcohol and experienced more alcohol-related harm than other drinkers. There was insufficient evidence to conclude that AED led to increased alcohol consumption or altered the nature of alcohol-related harm. However, AED consumers reported that AED increased stimulation and alertness, offset fatigue from drinking, and facilitated drinking. Experimental research also found that combining ED or caffeine with alcohol increased stimulation and alertness, offset alcohol-related fatigue and increased the desire to keep drinking. It did not change BAC, perceived intoxication, perceived impairment and it did not reverse alcohol-induced impairment on simple psychomotor tasks. Combining ED/caffeine with alcohol reduced alcohol-induced impairment on some but not all aspects of complex tasks. Although few in number, studies with industry ties presented contrary evidence. A growing body of evidence suggests that AED may facilitate drinking and related harms via its effects on intoxication but a causal link needs to be confirmed. The influence of industry involvement in this area of research needs to be monitored. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The purpose of this study was to determine if a brief 10-item alcohol-related Facebook® activity (ARFA) questionnaire would predict alcohol use patterns in college students (N = 146). During a single laboratory session, participants first privately logged on to their Facebook® profiles while they completed the ARFA measure, which queries past 30 day postings related to alcohol use and intoxication. Participants were then asked to complete five additional questionnaires: three measures of alcohol use (the Alcohol Use Disorders Identification Test [AUDIT], the Timeline Follow-Back [TLFB], and the Personal Drinking Habits Questionnaire [PDHQ]), the Barratt Impulsiveness Scale (BIS-11), and the Marlowe-Crowne Social Desirability Scale (MC-SDS). Regression analyses revealed that total ARFA scores were significant predictors of recent drinking behaviors, as assessed by the AUDIT, TLFB, and PDHQ measures. Moreover, impulsivity (BIS-11) and social desirability (MC-SDS) did not predict recent drinking behaviors when ARFA total scores were included in the regressions. The findings suggest that social media activity measured via the ARFA scale may be useful as a research tool for identifying risky alcohol use. PMID:28138317

One out of 2 Americans report drinking on a routine basis, making the excessive consumption of alcohol the third leading cause of preventable death in America (). Alcoholism and depression are common comorbidities that home healthcare professionals frequently encounter. To achieve the best patient outcomes, alcoholism should be addressed initially. Although all age groups are at risk, alcoholism and depression occur in more than 8 percent of older adults. Prevention through identifying alcohol use early in adolescence is vital to reduce the likelihood of alcohol dependence. This article provides an overview of the long-term effects of alcohol abuse, including alcoholic cirrhosis and hepatic encephalopathy. The diagnostic criteria for substance dependence and ideas for nonthreatening screening questions to use with patients who are adolescent or older are discussed. While providing patient care, home healthcare nurses share the patient's intimate home environment. This environment is perceived as a safe haven by the patient and home care nurses can take advantage of counseling and treatment opportunities in this nonthreatening environment.

Salicylate, the active ingredient of aspirin can cause sensorineural hearing loss and tinnitus when plasma concentrations reach a critical level. The ototoxic mechanisms of salicylate remain unclear but hearing and tinnitus usually recovers a few days after intoxication. There have been few reports of salicylate-induced ototoxicity in Korea, and the majority is caused by a low dose of aspirin. Herein, we report a case of sudden hearing loss and tinnitus after acute salicylate intoxication and review recent updates on salicylate ototoxicity.
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 schools 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

Alcohol consumption can prime motivation to continue drinking and may contribute to excessive drinking. Most alcohol administration research assesses the effect of a single alcohol dose on outcome measures; however, this differs from typical drinking occasions in which several drinks are consumed over time. This research tracks priming measures (alcohol urge, latency to first sip, and consumption time) and subjective effects (intoxication, stimulation, and sedation) across consumption of 5 drinks, over a period of 2.5 hours. Alcohol, placebo, and no-alcohol (i.e., soft drink) conditions are compared with isolate the effects of alcohol expectancies and differentiate these from alcohol's pharmacological effects. Alcohol urge and subjective state were measured before and after an initial drink was consumed (preload: alcohol, placebo, or no-alcohol). Four additional drinking phases followed whereby participants had access to 2 drinks (alcohol/no-alcohol, or placebo/no-alcohol). Experimental priming (urge, latency to first sip, consumption time) and subjective effect (intoxication, stimulation, and sedation) outcomes were recorded after each drink. The pattern of alcohol urge following placebo drinks differed compared with alcohol and no-alcohol consumption, Fs(1, 90) > 4.10, ps alcohol condition, while in the alcohol condition urge increased after the first few drinks before decreasing. Urge ratings showed the opposite pattern in the placebo condition (a decrease followed by an increase). Alcohol produced the highest ratings of lightheadedness, F(5, 440) = 2.8, p alcohol and placebo produced increased sedated feelings, Fs ≥ 19.05, ps ≤ 0.001. After placebo, urge was positively related to liking and enjoying the "alcoholic" drinks and feeling more stimulated (rs ≥ 0.31, ps ≤ 0.01). In social drinkers, different factors may affect priming during different stages of a drinking episode. For example, the pharmacological effects of alcohol appear

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

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

Oral methanol intoxication is common, but dermal intoxication is rare. We report a previously healthy 19-month-old female infant admitted to the emergency department (ED) with vomiting and tonic-clonic seizure. On physical examination, she was comatose and presented signs of decompensated shock with Kussmaul breathing. Her left thigh was edematous, with purple coloration. Methanol intoxication was suspected due to high anion gap metabolic acidosis (pH, 6.89; HCO3, pediatric intensive care unit, and methanol levels decreased to 0 mg/dL after 12 hours. During follow-up, massive edema and subarachnoid hemorrhage in the occipital lobe were detected by computed tomography of the brain. The patient died after 7 days.Although methanol intoxication occurs predominantly in adults, it must be considered in children with high-anion gap metabolic acidosis. This case report demonstrates that fatal transdermal methanol intoxication can occur in children, and it is the second report in the English literature of transdermal methanol intoxication in an infant.

Some criteria were evaluated, such as: intoxicating agent; patient's age and gender; place of event, cause, circumstances and severity of the intoxication; as well as signs and symptoms of the muscarinic, nicotinic and neurological effects. seventy patients (average age: 25 ± 19.97) formed the study's population. It was observed that 77.14% of them suffered carbamate intoxication. However, organophosphate intoxications were more severe, with 68.75% of patients presenting moderate to severe forms. Suicide attempt was the leading cause of poisoning, with 62 cases (88.57% of total). Atropine administration was an effective therapeutic approach for treating signs and symptoms, which included sialorrhea (p = 0.0006), nausea (p = 0. 0029) and emesis (p carbamates or organophosphates.

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

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

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

Emergency Departments (EDs) care for thousands of alcohol-intoxicated patients annually. No clinically relevant bedside measures currently exist to describe degree of impairment. To assess a group of bedside tests ("Hack's Impairment Index [HII] score") that applies a numerical value to the degree of alcohol-induced impairment in ED patients. A six-month retrospective review of HII score data was performed in a convenience sample of 293 intoxicated ED patients. Patients were scored 0-4 on five tasks, divided by the maximum score (20 if all tasks completed), every 2 hours; and classified by the number of visits: Low-frequency (1 visit); Medium-frequency (2 visits); High-frequency (≥3 visits). Correlations were assessed between HII score, healthcare provider judgment of intoxication, and measured alcohol levels. Study patients had 513 visits; 236 were low-frequency, 26 middle-frequency and 31 high-frequency. Clinical assessment and HII score were strongly correlated (Spearman's rho = 0.82, p < 0.001); clinical assessment and alcohol level less strongly so (rho = 0.49, p < 0.001). Among low-frequency patients, HII score and alcohol level were weakly correlated (r = 0.324, p < 0.001), with no such correlation among high-frequency visitors (r = -0.04, p = 0.89). The mean decline between serial HII scores was 0.126 (95% CI: 0.098-0.154). This pilot study shows the HII score can be performed at the bedside of alcohol-intoxicated patients. The HII declines in a reasonably predictable manner over time; and applies a quantitative, objective assessment of alcohol impairment.

The morbidity and mortality in developed countries is related to habits acquired in adolescence. Alcohol is the drug most consumed by Spanish adolescents, making its abuse a concern for public health. To evaluate the pattern of alcohol consumption of 4th year secondary school pupils in the city of Gandia, the defining characteristics of this population and the environment in which this takes place. This is a descriptive study of alcohol use in adolescents aged 15 to 18 years of Gandia, which was carried out through a survey of different issues related to health habits, nine of which relate to consumption alcohol. Of the 346 adolescents surveyed, 98% were minors, 93.3% had tried an alcoholic drink. Just under half (48.5%) took part in street binge-drinking, and 45.5% had got drunk at least once. Consumption was mainly during the weekend. More than three-quarters (76.6%) had their first contact with alcohol in the family. Alcohol use among adolescents is high, with consumption is mostly at weekends and with a high prevalence of alcohol intoxication, drinking in public places, and with friends.

In 'binge drinking' cultures, there is a strong association between alcohol consumption and violence. At the same time, several studies suggest that this link is cultural and contextual. We explore the role of alcohol in incidents of violence in nightlife settings. We used qualitative interviews with 104 Norwegians (52 men and 52 women, mean age 25 years) who binge drink and party in nightlife settings. Alcohol both sparks and constrains violence in these contexts. When participants use alcohol, they expect conflicts to occur and blame alcohol intoxication for such behaviour. The packed settings of nightlife and parties combined with the effects of alcohol can induce violence through personal affronts, heightened emotions and jealousy. At the same time, nightlife settings constrain violence. That is, binge drinkers excuse misbehaviour when it is attributed to alcohol. In addition, audiences in these setting often go to great lengths to stop fights. Combined, these factors help explain why violence occurs and why it usually does not escalate. The association between alcohol and violence can be understood by more closely examining the cultural and situational context where the events occur. This link is not primarily related to the psychopharmacological properties of alcohol, but rather it is associated with situational factors and cultural norms regarding how to behave while intoxicated. Strategies aiming at reducing violence in nightlife should take such factors into consideration. [Pedersen W, Copes H, Sandberg S.

Legal issues around the duty of care in common law with regard to addictive legal drugs are evolving. Two recent cases came before the Irish courts dealing with the issue of duty of care of alcohol suppliers to intoxicated individuals. In both cases the intoxication was self-induced and the consequences were lethal. The juxtaposition of personal autonomy and duty of care cannot ignore personal responsibility.

Full Text Available Abstract Background Both early alcohol debut, behavioural and health problems are reported to enhance adolescence substance use. This prospective study investigate the influence of behavioural and health problems on adolescents' alcohol and drug use. Method Prospective population based cohort study of 2 399 adolescents attending the Young-HUNT study, aged 13-15 at baseline in 1995/97, and 17-19 at follow-up 4 years later. Exposure variables were self reported conduct problems, attention problems, anxiety and depressive symptoms, and muscular pain and tension. Outcome variables at follow-up were frequent alcohol use and initiation of drug use. Associations were estimated by logistic regression models, influence of gender and drinking status at baseline were controlled for by stratification. Results At follow-up 19% of the students drank alcohol once a week or more frequently. Baseline conduct problems (OR 2.2, CI 1.7-3.0 and attention problems (OR 1.5, CI 1.2-2.0 increased the risk for frequent alcohol use at follow-up in the total population. Girls who had experienced alcohol-intoxications at baseline showed strong association between baseline problems and frequent alcohol use at follow-up. Conduct problems (OR 2.5, CI 1.3-4.8, attention problems (OR 2.1, CI 1.2-3.4, anxiety/depressive symptoms (OR 1.9, CI 1.1-3.1 and muscular pain and tension (OR 1.7, CI 1.0-2.9 all were associated with frequent alcohol use among early intoxicated girls. 14% of the students had tried cannabis or other drugs at follow-up. Conduct problems at baseline increased the odds for drug use (OR 2.6, CI 1.9-3.6. Any alcohol intoxications at baseline, predicted both frequent alcohol use (boys OR 3.6, CI 2.4-5.2; girls OR 2.8, CI 1.9-4.1, and illegal drug use (boys OR 4.7; CI 3.2-7.0, girls OR 7.7, CI 5.2-11.5 within follow-up. Conclusions Conduct problems in high-school more than doubles the risk for both frequent alcohol use and initiation of drug use later in adolescence

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.

To evaluate the usefulness of plasma glucose and serum cholinesterase levels as predictors of organophosphate-induced intermediate syndrome. Seventy-one organophosphate poisoning patients who were admitted to our emergency department during a 4-year period were evaluated retrospectively. Four patients were excluded from the study due to a lack of medical records. Categorical variables were analyzed using the chi-square test and nonparametric variables were analyzed using the Mann-Whitney U test. Thirty-five (52.2%) patients were male and 32(47.8%) were female. Patients had a mean age of 39.4 ± 15.9 years and 70.1% of the patients were married. Oral intake (68.7%) was the most common method of intoxication, and attempted suicide (67.2%) was the most common cause. The most common organophosphates were methamidophos (20.8%), dichlorvos (19.4%), parathion (7.5%), and methyl parathion (7.5%). Fifty-seven (85%) patients were treated in the emergency observation unit and 10 (15%) patients were admitted to the intensive care unit. Eleven (16%) patients developed intermediate syndrome and had significantly lower levels of serum cholinesterase (P organophosphate-induced intermediate syndrome.

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

Senna occidentalis (So) is a weed that grows in pastures along fences and in fields cultivated with cereals such as corn and soybean, and many reports have been showing intoxication with this plant in different animal species. It is also used in many medicinal purposes. The objective of the present study was to better evaluate the toxic effects of prolonged administration of So seeds to rats. Forty male Wistar rats were divided into four groups of 10 animals each, three of them respectively fed rations containing 1%, 2% and 4% So seeds, and the last one (control) fed commercial ration for a period of 2 weeks. Fourteen rats were also used in a pair-feeding (PF) experiment. The rats of the experimental groups showed lethargy, weakness, recumbency, depression and emaciation. Two rats of the 4% group and two of the PF group died during the experiment. Histopathological study showed fiber degenerations in the skeletal (Tibial, pectoral and diaphragm) and cardiac muscles. In the liver parenchyma, was observed vacuolar degeneration and, in the kidney, mild nefrosis in the proximal convoluted tubules. All of these alterations occurred in a dose-dependent fashion. Moderate to severe degeneration and spongiosis in the central nervous system, especially in cerebellum. Electron microscopy revealed mitochondrial lesions in all analyzed tissues.

Full Text Available The 21st-century epidemic of pharmaceutical and other drug-intoxication deaths in the United States (US has likely precipitated an increase in misclassified, undercounted suicides. Drug-intoxication suicides are highly prone to be misclassified as accident or undetermined. Misclassification adversely impacts suicide and other injury mortality surveillance, etiologic understanding, prevention, and hence clinical and public health policy formation and practice.To evaluate whether observed variation in the relative magnitude of drug-intoxication suicides across US states is a partial artifact of the scope and quality of toxicological testing and type of medicolegal death investigation system.This was a national, state-based, ecological study of 111,583 drug-intoxication fatalities, whose manner of death was suicide, accident, or undetermined. The proportion of (nonhomicide drug-intoxication deaths classified by medical examiners and coroners as suicide was analyzed relative to the proportion of death certificates citing one or more specific drugs and two types of state death investigation systems. Our model incorporated five sociodemographic covariates. Data covered the period 2008-2010, and derived from NCHS's Multiple Cause-of-Death public use files.Across states, the proportion of drug-intoxication suicides ranged from 0.058 in Louisiana to 0.286 in South Dakota and the rate from 1 per 100,000 population in North Dakota to 4 in New Mexico. There was a low correlation between combined accident and undetermined drug-intoxication death rates and corresponding suicide rates (Spearman's rho = 0.38; p<0.01. Citation of 1 or more specific drugs on the death certificate was positively associated with the relative odds of a state classifying a nonhomicide drug-intoxication death as suicide rather than accident or undetermined, adjusting for region and type of state death investigation system (odds ratio, 1.062; 95% CI,1.016-1.110.

Several [ 18 F]-FDG positron emission tomography (PET) studies in alcoholics have consistently reported decreases in overall brain glucose metabolism at rest and following acute alcohol administration. However, changes in cerebral glucose utilization associated with the transition to addiction are not well understood and require longitudinal translational imaging studies in animal models of alcoholism. Here, we studied brain glucose uptake in alcohol drinking rats in order to provide convergent evidence to what has previously been reported in human studies. Brain glucose metabolism was measured by [ 18 F]-FDG microPET imaging in different male Wistar rat groups: short-term drinking (three months), long-term drinking (twelve months) and alcohol-naïve. Global and regional cerebral glucose uptake was measured at rest and following acute alcohol administration. We showed that alcohol significantly reduced the whole-brain glucose metabolism. This effect was most pronounced in the parietal cortex and cerebellum. Alcohol-induced decreases in brain [ 18 F]-FDG uptake was most apparent in alcohol-naïve rats, less intense in short-term drinkers and absent in long-term drinkers. The latter finding indicates the occurrence of tolerance to the intoxicating effects of alcohol in long-term drinking individuals. In contrast, some regions, like the ventral striatum and entorhinal cortex, showed enhanced metabolic activity, an effect that did not undergo tolerance during long-term alcohol consumption. Our findings are comparable to those described in human studies using the same methodology. We conclude that [ 18 F]-FDG PET studies in rat models of alcoholism provide good translation and can be used for future longitudinal studies investigating alterations in brain function during different stages of the addiction cycle.

Binge drinking is prevalent and has serious biomedical consequences. In children, adolescents, and young adults, it is a prominent risk factor for later development of alcohol-use disorders. Many preclinical models have been employed to study the genetic risks for and biomedical consequences of alcohol drinking. However, these models historically did not result in blood-alcohol concentrations (BACs) exceding 80 mg%; this relatively modest level is the threshold that currently defines a binge session, according to the NIAAA and CDC. Nevertheless, in alcohol-dependent rodents, binge drinking has been well documented. Key neurobiological substrates localized to brain reward and stress systems have been identified. Studies of newer models of binge drinking without dependence are reviewed here. In these models, rodents, non-human primates, and flies will drink enough to reach high BACs. They often display observable signs of intoxication. The neurobiological consequences of these episodes of binge drinking without dependence are reviewed, preliminary evidence for roles for GABA, glutamate, opioid peptides, and corticotropin releasing factor are discussed, as is the need for more work to identify the antecedents and consequences of binge drinking in both animal models and humans.

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.

Although an association between adolescent sleep and substance use is supported by the literature, few studies have characterized the longitudinal relationship between early adolescent sleep and subsequent substance use. The current study examined the prospective association between the duration and quality of sleep at age 11 and alcohol and cannabis use throughout adolescence. The present study, drawn from a cohort of 310 boys taking part in a longitudinal study in Western Pennsylvania, includes 186 boys whose mothers completed the Child Sleep Questionnaire; sleep duration and quality at age 11 were calculated based on these reports. At ages 20 and 22, participants were interviewed regarding lifetime alcohol and cannabis use. Cox proportional hazard analysis was used to determine the association between sleep and substance use. After accounting for race, socioeconomic status, neighborhood danger, active distraction, internalizing problems, and externalizing problems, both the duration and quality of sleep at age 11 were associated with multiple earlier substance use outcomes. Specifically, less sleep was associated with earlier use, intoxication, and repeated use of both alcohol and cannabis. Lower sleep quality was associated with earlier alcohol use, intoxication, and repeated use. Additionally, lower sleep quality was associated with earlier cannabis intoxication and repeated use, but not first use. Both sleep duration and sleep quality in early adolescence may have implications for the development of alcohol and cannabis use throughout adolescence. Further studies to understand the mechanisms linking sleep and substance use are warranted. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Since the advent of energy drinks in the U.S. marketplace, some defendants have claimed that positive breath alcohol test results have occurred due to the ingestion of non-alcoholic energy drinks. A variety of energy drinks were tested by gas chromatography and some 88.9% (24 of 27) were found to contain low concentrations of ethanol (5-230 mg/dL). Drinks were then consumed (24.6-32 oz) by volunteers to determine the extent of reaction that could be achieved on a portable breath-testing instrument. Eleven of 27 (40.7%) beverages gave positive results on a portable breath-testing instrument (0.006-0.015 g/210 L) when samples were taken within 1 min of the end of drinking. All tests taken by portable breath test, DataMaster, and Intox EC/IR II at least 15 min after the end of drinking resulted in alcohol-free readings (0.000 g/210 L). Affording subjects a minimum 15-min observation period prior to breath-alcohol testing eliminates the possibility that a small false-positive alcohol reading will be obtained.

Full Text Available Summary Objectives: to evaluate and indicate the procedure to be followed in the health unit, both for diagnosis and the treatment of acute exogenous intoxications by carbamates or organophosphates. Methods: a descriptive study based on retrospective analysis of the clinical history of patients diagnosed with intoxication by carbamates or organophosphates admitted at the emergency unit of the Hospital de Urgências de Sergipe Governador João Alves (HUSE between January and December of 2012. Some criteria were evaluated, such as: intoxicating agent; patient's age and gender; place of event, cause, circumstances and severity of the intoxication; as well as signs and symptoms of the muscarinic, nicotinic and neurological effects. Results: seventy patients (average age: 25±19.97 formed the study's population. It was observed that 77.14% of them suffered carbamate intoxication. However, organophosphate intoxications were more severe, with 68.75% of patients presenting moderate to severe forms. Suicide attempt was the leading cause of poisoning, with 62 cases (88.57% of total. Atropine administration was an effective therapeutic approach for treating signs and symptoms, which included sialorrhea (p=0.0006, nausea (p=0. 0029 and emesis (p lt0.0001. The use of activated charcoal was shown effective, both in combating the signs and symptoms presented by both patient groups (p <0.0001. Conclusion: it is concluded that the use of atropine and activated charcoal is highly effective to treat the signs and symptoms developed by patients presenting acute exogenous intoxication by carbamates or organophosphates.
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.

We reviewed records of adult patients admitted to our burn unit who were reported to abuse drugs or alcohol from 1985 to 1988. The proportion of patients reported as abusing drugs increased significantly from 1987 to 1988, compared to previous years. However, there was no increase in the proportion of patients reported to abuse alcohol. Patients identified as abusing drugs had longer hospital stays, compared to patients who were not reported to abuse substances. Methamphetamine and cocaine were the drugs most often abused by patients who abused drugs or both drugs and alcohol. Mechanisms of burn injury in these patients included "accidental" burn injury related to acute intoxication, and self-injury due to psychosis or depression.

Caffeinated alcoholic beverage (CAB) consumption is a rapidly growing phenomenon among young adults and is associated with a variety of health-risk behaviors. The current study examined whether either caffeinated alcohol or the expectation of receiving caffeinated alcohol altered affective, cognitive and behavioral outcomes hypothesized to contribute to risk behavior. Young adult social drinkers (N=146) participated in a single session where they received alcohol (peak Breath Alcohol Content = .088 g/dL, SD = .019; equivalent to about 4 standard drinks) and were randomly assigned to one of four further conditions 1) no caffeine, no caffeine expectancy, 2) caffeine and caffeine expectancy, 3) no caffeine but caffeine expectancy, 4) caffeine but no caffeine expectancy. Participants’ habitual CAB consumption was positively correlated with measures of impulsivity and risky behavior, independently of study drugs. Administration of caffeine (mean dose = 220 mg, SD = 38; equivalent to about 2.75 Red Bulls) in the study reduced subjective ratings of intoxication and reversed the decrease in desire to continue drinking, regardless of expectancy. Caffeine also reduced the effect of alcohol on inhibitory reaction time (faster incorrect responses). Participants not expecting caffeine were less attentive after alcohol, whereas participants expecting caffeine were not, regardless of caffeine administration. Alcohol decreased response accuracy in all participants except those who both expected and received caffeine. Findings suggest that CABs may elevate risk for continued drinking by reducing perceived intoxication, and by maintaining the desire to continue drinking. Simply expecting to consume caffeine may reduce the effects of alcohol on inattention, and either expecting or consuming caffeine may protect against other alcohol-related performance decrements. Caffeine, when combined with alcohol, has both beneficial and detrimental effects on mechanisms known to contribute to

This study investigated the impact of mild-moderate dehydration on alcohol-induced deteriorations in cognitive functions. Sixteen healthy males participated in a single-blind, placebo-controlled cross-over design study involving 4 experimental trials (separated by ≥7 d). In each trial, participants were dehydrated by 2.5% body mass through exercise. After 1 h recovery in a thermo-neutral environment (22 ± 2 °C, 60-70% relative humidity) 4 tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB) were administered to the participants (test 1). In two of the trials, participants were provided with water equivalent to either 50% or 150% body mass loss and given salt (NaCl) capsules (50 mmol/L). A set volume of alcohol or placebo was then consumed in each trial, incorporating the conditions: dehydration-placebo (DP), dehydration-alcohol (DA), partial rehydration-alcohol (PA), and full rehydration-alcohol (FA). The same 4 CANTAB tasks were then re-administered (test 2). Subjective ratings of mood and estimates of alcohol intoxication and driving impairment were also recorded in each trial. Alcohol consumption caused deterioration on 3 of the 4 CANTAB measures (viz., choice reaction time, executive function and response inhibition). This reduction in performance was exacerbated when participants were dehydrated compared to trials where full rehydration occurred. Subjective ratings of impairment and intoxication were not significantly different between any of the trials where alcohol was consumed; however ratings for alcohol trials were significantly higher than in the placebo trial. These findings suggest that rehydration after exercise that causes fluid loss can attenuate alcohol-related deterioration of cognitive functions. This may pose implications for post match fluid replacement if a moderate amount of alcohol is also consumed. Copyright © 2013 Elsevier Inc. All rights reserved.

Young adulthood (ages 18-25 years) represents a time when high-risk behaviors, including alcohol and drug use, peak. Electronic music dance events (EMDEs) featured at clubs provide an ecologic niche for these high-risk behaviors. This paper examines the prevalence of alcohol and drug use among EMDE patrons. Examination of personal characteristics associated with exit levels of alcohol and drug use identifies important indicators of risk taking for prevention strategies. Data were collected anonymously during 2010-2012 from 2028 patrons as they entered and exited clubs in the San Francisco Bay area featuring EMDEs. Nearly half were aged ≤25 years. Biological measures of drug and alcohol and self-reported personal characteristics were attained. Analyses were completed in 2012. At entrance, more than one fifth of patrons were positive for drug use and one fourth arrived either impaired (blood alcohol concentration [BAC]: 0.05%-0.079%) or intoxicated (BAC: >0.08%) by alcohol. At exit, one fourth tested positive for drugs, and nearly half were impaired or intoxicated by alcohol. Individual characteristics that were important for levels of risk included prior alcohol use behaviors, sexual identity, ethnic/racial identity, and transportation to the event. Gender did not differentiate for alcohol use but fewer women used drugs. Findings confirm the importance of targeting EMDEs for prevention efforts. EMDEs attract young working adults who are engaged in heavy alcohol and/or drug use. Targeting these social settings for delivering public health prevention strategies regarding alcohol and drug use and related harm is indicated by the findings. © 2013 American Journal of Preventive Medicine.

This was a retrospective chart review to evaluate various risk factors associated with in-hospital mortality and intubation risk in acute methadone overdose. All patients admitted to an academic hospital in Tehran, Iran, during a 10-year period (2000-2009) constituted the study sample. Exclusion criteria were significant comorbidities and age under 18 years. Outcome variables were in-hospital mortality and being intubated during admission. A total of 802 patients were enrolled in the study. There were 15 (1.8%) deaths due to methadone overdose or its complications. The number of yearly admissions was 15 patients in 2000, 16 in 2001, 16 in 2002, 18 in 2003, 23 in 2004, 38 in 2005, 59 in 2006, 110 in 2007, 206 in 2008 and 301 in 2009. Based on logistic regression analysis, the most important independent variable predicting mortality was length of admission in toxicology ward [OR (95% CI): 1.6 (1.1-2.3)]. For the prediction of intubation, independent variables were Glasgow Coma Scale (GCS) score of 5-9 [OR (95% CI): 356.5 (9.8-12907.4)] in the emergency department (ED), miosis in the ED [356.9 (1.4-87872.5)] and respiratory rate in the ED [1.5 (1.1-2.1)]. Linear regression model for length of hospitalization showed patient age as the most important variable for prediction of this outcome. Despite a relatively low mortality rate, the increasing number of methadone-poisoned patients requires special attention to this common intoxication. Careful disposition of patients from ED to ordinary wards or intensive care units and also from higher to lower levels of care should be considered in methadone overdose. © 2015 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

Energy drinks are popular beverages that typically include high levels of caffeine and other ingredients such as taurine, or caffeine-containing herbs, such as guarana. While energy drinks are often consumed alone, they are also frequently used as mixers for alcoholic beverages. This review summarizes what is known about the scope of use of alcohol mixed with energy drinks (AmED), the risks associated with AmED, and the objective laboratory data examining how AmED differs from alcohol alone. The weight of the evidence reveals that AmED beverages are riskier than alcohol alone and constitute a public health concern. AmED beverage consumption is frequent, especially in young and underage drinkers. AmED use is associated with elevated rates of binge drinking, impaired driving, risky sexual behavior, and risk of alcohol dependence when compared with alcohol alone. Laboratory research (human and animal) has demonstrated that AmED beverages lead to altered subjective states including decreased perceived intoxication, enhanced stimulation, and increased desire to drink/increased drinking compared to alcohol alone. Possible underlying mechanisms explaining these observations are highlighted. PMID:25293549
There is a widespread assumption that nitrogen narcosis is comparable to alcohol intoxication, a similarity that may extend to patterns of tolerance. It has been suggested this indicates evidence of a shared biological mechanism but there is a paucity of experimental data to support these claims. The current study aimed to test this assumption by comparing subjective (ratings) and behavioural (Digit Letter Substitution Test) responses to nitrogen narcosis and alcohol. Experiment 1 compared responses to narcosis in 39 participants posited to differ in tolerance based on prior exposure to alcohol (heavy/light drinkers) and narcosis (novice/experienced divers). Experiment 2 compared responses to narcosis and after a 0.5 g/kg dose of alcohol in 23 participants. In both experiments narcosis was measured at depths between 40 and 45m in the ocean off Port Vila, Vanuatu. Experiment 1 measured a significant decrement in the behavioural measure underwater, compared to baseline but failed to find any differential responding to narcosis between drinker or diving experience groups. In contrast, Experiment 2 found positive correlations between alcohol and narcosis on both subjective and behavioural measures, indicating those affected to a greater degree by alcohol were also affected to a greater degree by narcosis. These results support the contention of a relationship between nitrogen narcosis and alcohol, although the role of diving and drinking history, if any, remains obscure.

Alcoholic patients have been known to have brain atrophy and cognitive dysfunction. However, recent studies have reported bilateral signal hyperintensities of the globus pallidus on T1-weighted magnetic resonance imaging (MRI) in liver failure, findings that are typically associated with manganese intoxication. The present study compared brain atrophy on T1-weighted MRI, signal intensity ratios of the globus pallidus on T1-weighted MRI, whole blood manganese levels, and Wechsler Adult Intelligence Scale-Revised (WAIS-R) IQ parameters between alcoholics with and without liver cirrhosis, to investigate cognitive dysfunction, MRI findings and manganese levels in alcoholics. Pallidal hyperintensity was visually identified in 80% of alcoholic patients with liver cirrhosis. In addition, a significant correlation was seen between pallidal signal intensity (P.S.I.) ratio and blood manganese level. However, no significant correlations were found between pallidal signal intensity ratio and any of the WAIS-R parameters. These findings suggest that no direct connection exists between cognitive dysfunction and pallidal hyperintensity in alcoholic patients with liver cirrhosis. We confirmed that brain MRI in alcoholics could detect pallidal signal hyperintensity, suggesting severe liver dysfunction. In addition to diagnosis, brain MRI is useful for therapeutic psychoeducation to alcoholic patients with liver cirrhosis, visualizing the severe liver dysfunction. (author)

The differentiator model predicts that individuals with a positive family history of alcoholism (FHA) or heavy alcohol consumers will feel more sensitive to the effects of alcohol on the ascending phase of the blood alcohol content while feeling less sedated on the descending phase. This study tested whether subjective perceptions are sensitive to the slope of breath alcohol concentration (BrAC) and whether that sensitivity is associated with an FHA and/or recent drinking history (RDH). Family-history-positive (FHP, n = 27) and family-history-negative (FHN, n = 27) young adult nondependent drinkers were infused intravenously with alcohol in 2 sessions separated by 1 week. After 20 minutes, one session had an ascending BrAC (+3.0 mg%/min), while the other session had a descending BrAC (-1 mg%/min). The BrAC for both sessions at this point was approximately 60 mg%, referred to as the crossover point. Subjective perceptions of intoxication, high, stimulated, and sedation were sampled frequently and then interpolated to the crossover point. Within-subject differences between ascending and descending responses were examined for associations with FHA and/or RDH. Recent moderate drinkers reported increased perceptions of feeling intoxicated (p Subjective perceptions in young adult social drinkers depend on the slope of the BrAC when examined in association with RDH. These results support the differentiator model hypothesis concerning the ascending slope and suggest that moderate alcohol consumers could be at risk for increased alcohol consumption because they feel more intoxicated and high on the ascending slope. Subjects did not feel less sedated on the descending slope, contrary to the differentiator model but replicating several previous studies. Copyright © 2011 by the Research Society on Alcoholism.

The 21st-century epidemic of pharmaceutical and other drug-intoxication deaths in the United States (US) has likely precipitated an increase in misclassified, undercounted suicides. Drug-intoxication suicides are highly prone to be misclassified as accident or undetermined. Misclassification adversely impacts suicide and other injury mortality surveillance, etiologic understanding, prevention, and hence clinical and public health policy formation and practice. To evaluate whether observed variation in the relative magnitude of drug-intoxication suicides across US states is a partial artifact of the scope and quality of toxicological testing and type of medicolegal death investigation system. This was a national, state-based, ecological study of 111,583 drug-intoxication fatalities, whose manner of death was suicide, accident, or undetermined. The proportion of (nonhomicide) drug-intoxication deaths classified by medical examiners and coroners as suicide was analyzed relative to the proportion of death certificates citing one or more specific drugs and two types of state death investigation systems. Our model incorporated five sociodemographic covariates. Data covered the period 2008-2010, and derived from NCHS's Multiple Cause-of-Death public use files. Across states, the proportion of drug-intoxication suicides ranged from 0.058 in Louisiana to 0.286 in South Dakota and the rate from 1 per 100,000 population in North Dakota to 4 in New Mexico. There was a low correlation between combined accident and undetermined drug-intoxication death rates and corresponding suicide rates (Spearman's rho = 0.38; psuicide rather than accident or undetermined, adjusting for region and type of state death investigation system (odds ratio, 1.062; 95% CI,1.016-1.110). Region, too, was a significant predictor. Relative to the South, a 10% increase in drug citation was associated with 43% (95% CI,11%-83%), 41% (95% CI,7%-85%), and 33% (95% CI,1%-76%) higher odds of a suicide

Binge drinking during adolescence is common and may predict increased drinking in young adulthood and enhanced risk of alcohol dependence. Variation in level of response to the hedonic and adverse effects of alcohol is in part an inherited factor that may also influence its use, abuse, and dependence. This study investigated, in young adults, whether an association could be demonstrated between variation in self-reported responses to alcohol and a history of binge drinking during adolescence. Young adult (18 to 30 years, n = 790) Native Americans and Mexican Americans were recruited from the community and completed a structured diagnostic interview. Response to alcohol was indexed using the expectation version of the Subjective High Assessment Scale (SHAS-E). An adolescent history of regular binge drinking was defined as drinking 5 or more drinks for boys and 4 or more drinks for girls per drinking occasion at least once a month during their highest drinking period prior to the age of 18. An adolescent history of regular binge drinking was found to be associated with a lower level of self-reported responses to the negative aspects of alcohol intoxication (feeling terrible) as well as to the overall level of intoxication, but not to the positive impressions of intoxication (feeling great) on the SHAS-E. A history of regular adolescent binge drinking was also correlated with less feelings of the "terrible" and "total" effects of alcohol, as indexed by the SHAS-E, in a linear regression model that included several diagnostic and demographic variables such as a history of conduct disorder and current levels of drinking. These data suggest that a history of adolescent binge drinking is associated with a reduction in the self-reported level of intoxication in young adulthood, a factor that could theoretically lead to increased risk of alcohol dependence.

During alcohol intoxication the human brain increases metabolism of acetate and decreases metabolism of glucose as energy substrate. Here we hypothesized that chronic heavy drinking facilitates this energy substrate shift both for baseline and stimulation conditions. To test this hypothesis we compared the effects of alcohol intoxication (0.75g/kg alcohol versus placebo) on brain glucose metabolism during video-stimulation (VS) versus when given with no-stimulation (NS), in 25 heavy drinkers (HD) and 23 healthy controls each of whom underwent four PET- 18 FDG scans. We showed that resting whole-brain glucose metabolism (placebo-NS) was lower in HD than controls (13%, p=0.04); that alcohol (compared to placebo) decreased metabolism more in HD (20±13%) than controls (9±11%, p=0.005) and in proportion to daily alcohol consumption (r=0.36, p=0.01) but found that alcohol did not reduce the metabolic increases in visual cortex from VS in either group. Instead, VS reduced alcohol-induced decreases in whole-brain glucose metabolism (10±12%) compared to NS in both groups (15±13%, p=0.04), consistent with stimulation-related glucose metabolism enhancement. These findings corroborate our hypothesis that heavy alcohol consumption facilitates use of alternative energy substrates (i.e. acetate) for resting activity during intoxication, which might persist through early sobriety, but indicate that glucose is still favored as energy substrate during brain stimulation. Our findings are consistent with reduced reliance on glucose as the main energy substrate for resting brain metabolism during intoxication (presumably shifting to acetate or other ketones) and a priming of this shift in heavy drinkers, which might make them vulnerable to energy deficits during withdrawal

To test this hypothesis, we compared the effects of alcohol intoxication (0.75 g/kg alcohol vs placebo) on brain glucose metabolism during video stimulation (VS) versus when given with no stimulation (NS), in 25 heavy drinkers (HDs) and 23 healthy controls, each of whom underwent four PET-(18)FDG scans.

The rate of alcohol-related emergency department (ED) presentations in young people has increased dramatically in recent decades. Injuries are the most common type of youth alcohol-related ED presentation, yet little is known about these injuries in young people. This paper describes the characteristics of alcohol-related ED injury presentations in young people over a 13-year period and determines if they differ by gender and/or age group (adolescents: 12-17 years; young adults: 18-24 years). The Queensland Injury Surveillance Unit (QISU) database collects injury surveillance data at triage in participating EDs throughout Queensland, Australia. A total of 4667 cases of alcohol-related injuries in young people (aged 12-24 years) were identified in the QISU database between January 1999 and December 2011, using an injury surveillance code and nursing triage text-based search strategy. Overall, young people accounted for 38% of all QISU alcohol-related ED injury presentations in patients aged 12 years or over. The majority of young adults presented with injuries due to violence and falls, whereas adolescents presented due to self-harm or intoxication without other injury. Males presented with injuries due to violence, whereas females presented with alcohol-related self-harm and intoxication. There is a need for more effective ways of identifying the degree of alcohol involvement in injuries among young people presenting to EDs. © 2014 Australasian Professional Society on Alcohol and other Drugs.
Full Text Available Objective: The aim of the study is to analyze the general aspects of cases with carbon monoxide intoxication in order to improve the approach to future patients. Material and Methods: The hospital records of 84 children (mean age 4.71±2.64 years; 48 male, 36 female who had been admitted to Paediatric Emergency Department for carbon monoxide intoxication between October 2007 and February 2009, were retrospectively evaluated in a descriptive analysis.Results: The source of carbon monoxide intoxication was heaters, waterheaters and fi re in 82.1%, 7.1% and 6% of cases, respectively. There was a statistically signifi cant difference between the carboxyhemoglobin levels of the patients according to the clinical classifi cation (p<0.05. The intoxication caused by heaters was observed signifi cantly in November, December and January (p<0.001, between 16:00-24:00 hours (p<0.001 and among more than one member of a family (p<0.001. A medium level correlation was detected between the treatment approach and clinical classifi cation (r=0.50, p<0.001. Conclusion: Carbon monoxide intoxication, in the presented series, was found to develop accidentally; mostly in the Winter season; during night hours when the family members gathered together. The carboxyhemoglobin levels were appropriate with the developing clinical findings. Carboxyhemoglobin level solely was not enough for achieving the diagnosis and planning the treatment.

The effect of lead (Pb) intoxication during pregnancy and lactation on the male reproductive system was studied to evaluate the alterations caused by Pb in the development of pups. The investigations covered the effect of lead on the course of spermatogenesis and the development of the epididymis and reproductive glands. For this purpose, dams were intoxicated with 300 mg/L Pb during the gestational period and through lactation. Pups were sacrificed on Postnatal (PN) Days 12 and 21. Blood lead (PbB) and plasma iron concentrations were measured, and blood cells counted. Biochemical studies as well as histochemical analyses were performed on testes and accessory glands of the reproductive system. Lead intoxication resulted in a decrease in testis and seminal vesicle weights and an increase in DNA and RNA levels on PN Day 21. Total protein was significantly decreased by the toxicant, and alkaline and acid phosphatase levels of the gonads were reduced. Effects were also reflected in the reduction of the thickness of epithelium and of seminiferous tubule diameter (STD) as a consequence of the action of lead in the reduction in numbers of prospermatogonia and spermatocytes. Results indicate that the reproductive system targets of lead intoxication are not only the testes; lead intoxication results in the inhibition of testicular, epididymal, and seminal vesicle function, altering the biochemical composition of these organs, and consequently, affecting the normal development of germinal cells.

Objective: To analyze the CT and MR manifestations of methyl alcohol toxic encephalopathy and to improve the diagnosing value of CT and MRI. Methods: 40 patients with methyl alcohol intoxication were collected in this study, in which CT scan was performed on 40 cases and MRI on 4 cases. All CT and MRI radiological data of brain were retrospectively studied. Results: 13 of 40 cases showed abnormal findings on brain CT and MRI. The most common manifestation (6/13, 46%)was hypodensity in frontal parietal white matter and external capsule-putamen on CT, which showed long or short T1 and long T2 on MR. Hemorrhage in right putamen was found only in 1 patient (1/13,7%). CT showed low density inbilateral external capsule in 4 cases (4/13,31%), in which MR showed long or short T1 and long T2. Low density lesions in subcortical white matter of bilateral frontal and parietal lobes, cingulate gyms and insular lobes were found in 2 patients (2/13,15%). The more severe clinic manifestation, the more obvious brain lesion CT and MRI showed. Conclusion: Brain CT and MR manifestations have great diagnostic value of acute methyl alcohol toxic encephalopathy. MRI was more sensitive and better than CT in finding early brain damage caused by methanol intoxication. (authors)
You are reminded that: - the legal blood alcohol limit in force under the Host States’ traffic regulations (0.5 g per 1000 ml of blood) also applies on the CERN site; - the consumption of alcohol is forbidden during working hours and is only tolerated in the restaurants at certain times, unless an exception is granted for special events (Operational Circular No. 8); - failure to observe these rules may result in disciplinary action by the Organization, independently of any sanctions that may be applicable pursuant to the road traffic regulations of the Host State concerned. Furthermore, the Reception and Access Control Service, the site guards and the Fire Brigade have been instructed to stop any driver in an obvious state of intoxication and to ask him/her to abandon the vehicle on the spot. In case of disagreement, they may also suggest that he/she submits to a voluntary blood alcohol level test at the CERN Medical Service or Fire Brigade. They will also stop and question any obviously intoxicate...

Patients suffering from major depressive disorder are more likely to suffer from alcohol use disorder. The data is inconclusive for the effectiveness of antidepressant treatment of patients suffering from both illnesses in regards to improving sobriety and reducing alcohol-related healthcare expenses such as hospitalizations. The objective of this study is to determine if a new prescription of an antidepressant upon inpatient discharge is associated with a reduction in the number of future acute alcohol-related hospital readmissions to the same institution in patients suffering from major depressive disorder and alcohol-use disorder. A retrospective, medical record review study was conducted at a publicly-supported hospital in Sylmar, CA. A query was performed for adult patients admitted between 1/1/2005-12/31/2013 who had ICD-9 codes for both alcohol-use disorder and depression. Index admission was the first hospitalization in which the patient was currently consuming alcohol and had depression as identified by physician documentation as a problem. Acute alcohol-related admissions were those for alcohol intoxication or withdrawal (indicating current alcohol use). Patients were excluded if they were receiving an antidepressant on index admission, depressive disorder with a prescription for an antidepressant is not associated with a reduction in future readmissions, nor significantly increase the number of days to readmission. The study does not support the concept of antidepressants in reducing acute alcohol-related readmissions.

Alcohol consumption among young people in New Zealand is on the rise. Given the broad array of acute and chronic harms that arise from this trend, it is a major cause for alarm and it is imperative that we improve our knowledge of key drivers of youth drinking. Changes wrought by the neoliberal political climate of deregulation that characterised the last two decades in many countries including Aotearoa (Aotearoa is a Maori name for New Zealand) New Zealand have transformed the availability of alcohol to young people. Commercial development of youth alcohol markets has seen the emergence of new environments, cultures and practices around drinking and intoxication but the ways in which these changes are interpreted and taken up are not well understood. This paper reports findings from a qualitative research project investigating the meaning-making practices of young people in New Zealand in response to alcohol marketing. Research data included group interviews with a range of Maori and Pakeha young people at three time periods. Thematic analyses of the youth data on usages of marketing materials indicate naturalisation of tropes of alcohol intoxication. We show how marketing is used and enjoyed in youth discourses creating and maintaining what we refer to as intoxigenic social environments. The implications are considered in light of the growing exposure of young people to alcohol marketing in a discussion of strategies to manage and mitigate its impacts on behaviour and consumption.

Transdermal alcohol monitoring is used extensively in forensic settings to identify whether individuals have violated court-ordered mandates to abstain from drinking. Despite widespread use in that setting, comparatively few studies have explored the clinical utility of transdermal alcohol monitoring. Furthermore, of the few studies conducted, most have relied on the forensically established conservative criteria to identify whether or not a drinking episode has occurred. Here, we explore how transdermal alcohol monitoring data can be used to estimate more clinically meaningful parameters relevant to clinical treatment programs. We developed a procedure to use transdermal data to objectively estimate the number of standardized drinks an individual has consumed. Participants included 46 men and women who consumed 1 to 5 beers within 2 hours in the laboratory on separate days while wearing devices to monitor transdermal alcohol concentrations (TAC). A mathematical model was derived to estimate the number of standardized alcohol drinks consumed, which included a number of variables (time-to-peak TAC, area under the TAC curve, and sex). The model was then validated by applying it to data from a separate study. Our results indicate that transdermal alcohol devices can be used to estimate the number of standard drinks consumed. Objective methods characterizing both the level of intoxication achieved and the number of drinks consumed, such as transdermal alcohol monitoring, could be useful in both research and treatment settings.

It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white...... men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence...

This multi-center study of dual diagnosis (DD) programs involved 804 residential patients with co-occurring alcohol and mental health disorders. The Addiction Severity Index was administered at admission and at one, six, and 12 months after discharge. Repeated measures analysis showed the intoxication rate per month stabilized between months six and 12 with 68% still in remission and an 88% mean reduction from baseline (F = 519, p treatment of both disorders and explained their effectiveness. Co-occurring DSM IV mood disorders such as anxiety and depression as well as drug abuse involving opioids or cocaine fell between 66 and 95% at months one, six, and twelve. PMID:28868159
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.

The purpose of the research was the study of nitrite impact on energy metabolism in salivary gland tissues in connection with chronic nitrate intoxication. The study has been carried out on 100 Wistar rats, weighing 160-250 g, which were divided into following groups: the 1st group consisted of intact rodents (control); the 2nd group consisted of experimental rodents, where chronic nitrate intoxication has been reproduced during 14, 30, 60 and 90 days. Intoxication leads to hypoxia, which complications cause tissue hypoxia. Has been established that prolonged intake of nitrates in low doses leads to their accumulation in salivary glands tissues all these result in derangement of metabolism at the intermembrane cellular level. At the same time energy metabolism in salivary glands is inhibited, resulting in their dysfunction at the excretory and endocrine levels.
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.

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)

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.

Mixing alcohol with diet beverages, as compared to mixing the same amount of alcohol with a regular beverage, is associated with greater intoxication. This may occur because diet mixers increase alcohol absorption rates. Thus, it is plausible that the use of diet mixers may increase the risk of alcohol-related harms. The current study sought to (1) determine the rate/frequency of use in among college students, (2) examine the relationship between mixing alcohol with diet beverages and alcohol-related problems, above typical alcohol use and sensation seeking, and (3) explore key traits (gender, restricting food while drinking, and body mass index [BMI]) that may characterize users. Participants were 686 (73% female) undergraduate students who completed self-reports of alcohol use (including diet mixer use), alcohol-related problems, eating behaviors while drinking, sensation seeking, and demographic information. Results revealed that about 36% of the sample reported consuming alcohol with diet mixers, and users typically consumed this beverage at least once a month. Students who reported mixing alcohol with diet beverages experienced more alcohol-related problems. And, the more frequently one consumed this beverage, the more problems were reported. These associations were found after controlling for typical level of alcohol use and sensation seeking. No differences were observed between user-status on gender, eating behaviors while drinking, and BMI. Our findings suggest that mixing alcohol with diet beverages could be a risk factor for experiencing more alcohol-related harms. Further research is needed to understand this relationship, as it may help guide intervening efforts aimed to reduce alcohol-related risks. Copyright © 2016 Elsevier Ltd. All rights reserved.

Craving is recognized as a formidable barrier in the management of patients with alcohol dependence. Among pharmacological agents that have been used in experimental studies for reduction in craving, baclofen appears to have a significant advantage over other agents. The study is retrospective chart review of patients ( n = 113) who have been treated with baclofen for alcohol dependence in a tertiary hospital of North India. Baseline assessments included sociodemography, motivation, quantity-frequency of alcohol use, and other alcohol-related clinical parameters. Weekly assessments, for a period of 4 weeks, were extracted from records which included dose of baclofen, craving intensity, and alcohol consumption. The study sample was predominantly male, mean age of 41.49 (±9.75) years, most having a family history of substance use (70.97%), and many reporting binge use pattern in last year (49.46%). Baseline assessment revealed 48.7% of the sample was in precontemplation phase for alcohol use and 70% reported severe and persistent craving. This persistent craving was reported by only 15% of the sample by the end of 4 weeks treatment with baclofen (20-40 mg/day). Thirty-four percent of patients reported continued problematic use of alcohol by the end of 4 weeks. Our clinical experience suggests that baclofen reduces craving and alcohol consumption including in those with poor motivation. The drug causes few side effects and does not add to the intoxication effect of alcohol. Considering that baclofen is safe in those with liver cirrhosis and reduces withdrawal symptoms due to alcohol, a controlled trial comparing it with standard treatment is required.
