Acute alcohol intoxication: a clinical overview.

Abstract: Alcohol is a legal and yet detrimental psychoactive substance, capable of establishing addiction and impacting the physical, mental, social, and economic health of people. Alcohol intake causes a large variety of tissue damages severely impacting the nervous system, digestive and cardiovascular systems and causing oral cavity, oropharyngeal, hypopharyngeal, esophageal, colon-rectal, laryngeal, liver and intrahepatic bile duct, and breast cancers. Alcohol can also play a role in the pathogenesis of diabetes mellitus, cardiomyopathy and hemorrhagic strokes. When drunk during pregnancy it is proved to be responsible for serious damage to fetuses causing a wide range of pathological conditions from miscarriage to Fetal Alcoholic Spectrum Disorder (FASD). Acute ethanol intoxication happens when the amount of alcohol consumed is greater than the disposal capacity of the liver, causing an accumulation of its metabolites displayed by initial dysphoria and disinhibition. Nausea, vomiting, memory loss could happen. Although, it can lead to more serious conditions like impaired speaking, impaired coordination, unstable gait, nystagmus, stupor, or coma. Respiratory depression and death could also happen in such cases. Unfortunately, diagnosis of acute alcohol intoxication is difficult because most of the drinkers deny or minimize their assumption. It is dramatically important to assess when the last intake happened to avoid withdrawal syndrome. Alcohol acute intoxication can be considered a serious harm to health and a relevant issue for healthcare provid-ers working in emergency rooms. Differential diagnosis is crucial to avoid serious outcomes. There is no consensus about therapies for acute intoxication, but supportive and symptomatic treatments were proved effective. The repercussions of alcohol misuse over drinkers' social, familiar, economical and working life enhance the importance of a multidisciplinary approach in such cases.

Neonatal acute ethanol intoxication during the epidemic of COVID-19: a case report.

BACKGROUND: After the outbreak of COVID-19, many families equip with 75% ethanol to inactivate the SARS-CoV-2, which increases the risk of exposure to ethanol. CASE PRESENTATION: We reported a 25-day-old newborn who was diagnosed with neonatal acute ethanol intoxication with a presenting complaint of accidental consumption about 15 ml formula milk containing 75% ethanol. His main clinical manifestations were irritability, flushed skin, tachycardia, tachypnea, and toxicology analysis detected ethanol. After timely gastric lavage and intravenous fluid replacement, he was cured and discharged. CONCLUSIONS: During the COVID-19 epidemic, high concentration ethanol used for inactivating SARS-COV-2 should be placed reasonably and neonatal feeding safety should be emphasized. Timely diagnosis and symptomatic treatment are essential for the prevention and management of acute ethanol intoxication in newborns.

Relationship between level of response to alcohol and acute tolerance.

BACKGROUND: A low level of response (low LR) to alcohol correlates with the later development of alcohol-related problems. Although some of the underpinnings of LR are understood, little is known about the potential relationship between LR and acute tolerance. The current analyses tested the hypothesis that a low LR will be explained in part by more intense acute tolerance to alcohol during a drinking session. METHODS: Data were generated through a reanalysis of data from 120 individuals who were 18- to 25-year-old, sex-matched pairs of low and high LR drinkers who at baseline did not meet criteria for an alcohol use disorder. Each subject participated in an oral alcohol challenge in which they consumed about 0.7 ml ethanol per kg and acute tolerance was measured as the differences in alcohol's effects at similar breath alcohol levels (BrACs) during the rising and falling breath alcohol concentration (BrAC) curve. Measures included aspects of the Subjective High Assessment Scale (SHAS) and body sway. RESULTS: Contrary to our hypothesis, but similar to results with other alcohol measures, acute tolerance was significantly attenuated in low LR compared with high LR individuals on most SHAS scores. Neither LR group demonstrated acute tolerance to alcohol for sleepiness or body sway. Men and women did not differ on any of these measures. CONCLUSION: These data do not support a role of acute tolerance in the low LR to alcohol as measured by subjective feelings of intoxication or body sway in these subjects, findings that were similar across males and females. In addition, consistent with the literature, the analyses demonstrated differences across measures such that acute tolerance was observed for most measures of subjective effects but not for body sway. Among the subjective effects, acute tolerance was observed for alcohol's intoxicating effect but not for feeling sleepy.

The role of tobacco smoking and illicit drug use in adolescent acute alcohol intoxication.

BACKGROUND: This study aims to determine the prevalence of tobacco smoking and illicit drug use among Dutch adolescents admitted to hospital for acute alcohol intoxication treatment. Furthermore, socio-demographic predictors for smoking and illicit drug use in the sample population will be studied. The relationship between illicit drug use and specific characteristics of intoxication, such as blood alcohol concentration (BAC) and duration of reduced consciousness is also investigated. METHODS: The national Dutch Paediatric Surveillance Unit was used to prospectively register cases of acute alcohol intoxication from 2007 through 2017. Cases were included if they met the following inclusion criteria: BAC > 0.0 g/L, aged between 10 to 18 years old and requiring hospital treatment due to reduced consciousness. Questionnaires were sent to paediatricians to obtain clinical information. RESULTS: During the period 2007-2017, 5322 cases that met the inclusion criteria were reported. In this patient group, the prevalence of tobacco smoking was 22.2% (CI 21.0-23.5%), while the prevalence of illicit drug use was 11.8% (CI 10.9-12.7%). The predictors for smoking were the absence of alcohol-specific parental rule-setting, lower educational level, non-traditional family structure and positive drug screening. The predictors for illicit drug use were the absence of alcohol-specific parental rule-setting and smoking. Illicit drug use was also associated with a lower BAC at the time of admission. CONCLUSIONS: Assessing smoking and illicit drug use among adolescents admitted for acute alcohol intoxication is important in acute cases of intoxication, for outpatient follow-up and for the purposes of prevention. The relationship between simultaneous illicit drug use and a lower BAC is of relevance for paediatricians' attempts to diagnose acute intoxication. With respect to outpatient follow-up and preventive measures, it is important to be aware that adolescents' alcohol consumption, tobacco and illicit drug use are related and, ultimately, increase the odds of using other substances.

Comparison of 4 tests' utility for predicting need for emergency department care in patients with alcohol-related complaints.

INTRODUCTION: Intoxication is a common presenting complaint in emergency departments (ED), but many patients with intoxication do not need emergency care. Three screens (BLINDED, Brown, and San Francisco) attempt to determine which intoxicated patients can be triaged to a lower level of care. METHODS: Observational multi-center cohort study of patients presenting to one of three ED with complaints consistent with acute intoxication. When a qualifying patient was brought to the emergency department, a team member interviewed the triaging provider. Interviews covered all three screens and the provider's gestalt. Receiver operating curve (ROC) analysis was used to determine which screen performed best. Cases were reviewed to determine need for emergency care. RESULTS: Of the 199 subjects studied, 91% (181/199) were male and were 50 years old on average (SD = 12 years). Of the 55 subjects tested (28%), their average alcohol level was 251 mg/dL (SD = 146 mg/dL). Only 117 subjects (59%) had complete information for inclusion in the final comparison of screens. Provider gestalt performed best (AUC = 0.69), but there were no meaningful differences between any of the screens (AUC = 0.62-0.66, p > 0.05 for all comparisons). Inability to sit up was sensitive for needing emergent care (88%), but it was non-specific (17%). Similarly, signs of trauma were specific (99%) for ED care, but insensitive (18%). CONCLUSIONS: The three formal screens and provider gestalt performed similarly.

L-Cysteine Containing Vitamin Supplement Which Prevents or Alleviates Alcohol-related Hangover Symptoms: Nausea, Headache, Stress and Anxiety.

AIMS: Alcohol-related hangover symptoms: nausea, headache, stress and anxiety cause globally considerable amount of health problems and economic losses. Many of these harmful effects are produced by alcohol and its metabolite, acetaldehyde, which also is a common ingredient in alcohol beverages. The aim of the present study is to investigate the effect of the amino acid L-cysteine on the alcohol/acetaldehyde related aftereffects. METHODS: Voluntary healthy participants were recruited through advertisements. Volunteers had to have experience of hangover and/or headache. The hangover study was randomized, double-blind and placebo-controlled. Nineteen males randomly swallowed placebo and L-cysteine tablets. The alcohol dose was 1.5 g/kg, which was consumed during 3 h. RESULTS: The primary results based on correlational analysis showed that L-cysteine prevents or alleviates hangover, nausea, headache, stress and anxiety. For hangover, nausea and headache the results were apparent with the L-cysteine dose of 1200 mg and for stress and anxiety already with the dose of 600 mg. CONCLUSIONS: L-cysteine would reduce the need of drinking the next day with no or less hangover symptoms: nausea, headache, stress and anxiety. Altogether, these effects of L-cysteine are unique and seem to have a future in preventing or alleviating these harmful symptoms as well as reducing the risk of alcohol addiction.

Case Report: Early Transplant Rejection of a Methanol-Intoxicated Donor Heart in a Young Female Patient. A Diagnostic Approach With CMR, Cardiac Biopsy, and Genetic Risk Assessment.

This case report describes the contributions of multimodality imaging, cardiac biopsy, and genetic sequencing to the diagnosis and management of heart transplant rejection in a 23-year old patient with dilated cardiomyopathy.

Teenage kicks: splenic rupture secondary following infectious mononucleosis.

A 16-year-old man was brought to the emergency department by his father with apparent alcohol intoxication. While in the department, it was noted that the patient had ongoing tachycardia, hypotension and abdominal pain. His recent medical history included a self-resolving illness of fatigue, muscle aches and sore throat. A CT scan of his abdomen revealed an enlarged spleen with a splenic infarct and rupture, likely secondary to infectious mononucleosis. The patient was treated conservatively for 12 days.

Comparison of age of first drink and age of first intoxication as predictors of substance use and mental health problems in adulthood.

BACKGROUND: International public policy on age of first alcoholic drink (AFD) has emphasised the long-term benefits of delaying AFD. This study aimed to compare AFD to age of first intoxication (AFI) as predictors of substance use disorder and mental disorder outcomes in adulthood. METHODS: Data were obtained from a longitudinal birth cohort in Christchurch, New Zealand. Participants were born in 1977. Analysis samples ranged from n = 1025 (age 18) to n = 962 (age 35). Measures of AFD and AFI were generated using parental- and self-report data collected from age 11. Outcomes at age 18-35 were alcohol quantity consumed, DSM-IV alcohol use disorder (AUD) and AUD symptoms, major depression, anxiety disorder, and nicotine, cannabis, and other illicit drug dependence. Covariate factors measured during childhood included family socioeconomic status, family functioning, parental alcohol-related attitudes/behaviours, and individual factors. RESULTS: There was a significant unadjusted association between AFD and symptoms of AUD (p < .001) and nicotine dependence (p < .05) but not other outcomes. AFI was significantly (p < .05) associated with all outcomes. After adjustment for covariates, the association between AFD and outcomes was not statistically significant. Conversely, in adjusted models, statistically significant (p < .05) associations remained between AFI and all AUD and substance use disorder outcomes but not alcohol consumption or mental disorder outcomes. CONCLUSIONS: AFI was a more robust predictor of adult substance use disorder outcomes than AFD. Public health and policy interventions aimed at prevention of long term harms from alcohol should therefore focus on AFI rather than AFD.

[Alcohol-associated mortality in Russia (based on the materials for the period from 2011 till 2016)]. / Alkogol'-assotsiirovannaia smertnost' v Rossii (po materialam 2011-2016 gg.).

The objective of the present study was to evaluate the frequency of alcoholic drunkenness documented during forensic medical expertises (investigations) of the corpses carried out in this country throughout the period from 2011 till 2016. The investigations were conducted with the use of medical statistics methods by calculating the fractional difference, dynamics, and rates of detection of the cases of alcoholic intoxication depending on the cause of death. The study has demonstrated the high frequency of the cases of alcoholic drunkenness revealed during forensic medical expertises (investigations) of the corpses that amounted to 30.5% [15, 16]. The total number of the corpses examined in 2016 was 8.6% higher than in 2011. The frequency of the documented cases of alcoholic drunkenness during the same period decreased by 19.7%. The frequency of the documented cases of alcoholic drunkenness in the cases of violent death was 2.8 times that in the cases of death from various diseases (52.8 and 19.0% respectively). The enhanced frequency of alcoholic drunkenness in relation to the number of the conducted forensic medical expertises was documented in the cases of death by drowning and from hypothermia whereas the lowest frequency of alcoholic intoxication was recorded for the corpses of the people who had died from malignant tumours and diseases of the nervous system. Various regions of Russia differed in terms of the frequency of alcoholic drunkenness recorded among the recently deceased people.

Should alcohol screening be a routine practice in alcohol-related facial trauma care? A narrative review.

The link between alcohol intoxication and Emergency Department (ED) attendance for management of alcohol-related injuries has been well documented. The acute settings such as ED and surgical wards may not be the most appropriate environment for treatment of chronic conditions, but traumatic episode presentation to ED may offer the most opportunistic time to focus on screening against harmful alcohol use in order to provide timely feedback and support. Although ED provides an opportunity to identify patients with alcohol problems, the initial challenge is finding suitable ways to identify and screen affected patients. This paper is a narrative review on methods of alcohol screening and its effectiveness and efficacy in trauma care setting. It is second part in a series on implementation of screening and brief intervention in managing trauma patients.

Factors associated with alcohol drinking behavior of cancer survivors: The Korean National Health and Nutrition Examination Survey.

BACKGROUND: This study aimed to evaluate the factors associated with drinking behavior of cancer survivors after cancer diagnosis. METHODS: The study subjects were 906 adult cancer survivors who had reportedly drunk alcohol before cancer diagnosis and participated in the Korean National Health and Nutrition Examination Surveys conducted from 2007 to 2013. Among them, 360 abstained from alcohol drinking after cancer diagnosis. We categorized remaining 546 persistent drinkers into high-risk drinker (consuming≥7 glasses of alcohol for men and≥5 glasses of alcohol for women at one sitting at the frequency of at least once a month) or moderate drinker. We used multiple logistic regression analysis to evaluate risk factors associated with drinking behavior. RESULTS: The high-risk drinkers occupied 27.1% (148 survivors) of the persistent alcohol drinking survivors. Age increase (OR=0.96; 95% CI 0.93-0.99), female sex (OR=0.15; 95% CI 0.08-0.28), and increase of time lapse (by 1-year) after cancer diagnosis (OR=0.94; 95% CI 0.92-0.97) were associated with a lower risk of high-risk drinking as compared with moderate drinking. Meanwhile,≤9years of education (OR=1.99; 95% CI 1.10-3.60), alcohol-related cancer (OR=2.09; 95% CI 1.23-3.56), and current smoking (OR=1.92; 95% CI 1.03-3.59) were associated with increased risk of high-risk drinking of cancer survivors. CONCLUSIONS: These findings suggest that greater efforts for preventing high-risk drinking should be laid on the cancer survivors, with consideration of individual sociodemographic characteristics, especially when the survivors had been diagnosed with alcohol-related cancer.

Identification and initial management of intoxication by alcohol and other drugs in the pediatric emergency room / Identificação e manejo inicial de intoxicações por álcool e outras drogas na sala de emergência pediátrica

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.

Resumo Objetivo: Revisar o rastreamento, o diagnóstico, a abordagem e o tratamento das intoxicações por álcool e outras drogas de crianças e adolescentes no contexto de emergência. Fontes dos dados: Foi feita uma revisão narrativa da literatura. Sumário dos achados: A detecção desse problema na sala de emergência pode ser um desafio, especialmente quando sua avaliação não é padronizada. O uso intencional e em grandes quantidades episódicas de substâncias psicoativas é o padrão em adolescentes e a intoxicação não intencional é mais comum em crianças menores de 12 anos. O quadro clínico em adolescentes e em crianças difere dos adultos e algumas particularidades são importantes no contexto de emergência. Após o manejo do quadro agudo, intervenções com vistas ao adolescente de risco podem ser efetivas. Conclusão: O diagnóstico e o tratamento das intoxicações por álcool e outras drogas em adolescentes e crianças em emergência requer uma avaliação sistemática do uso dessas drogas. Há poucos tratamentos específicos para intoxicação e o manejo é de apoio e das complicações clínicas relacionadas.

Intoxicación alcohólica / Alcohol intoxication

Resumen:La intoxicación se considera como una manifestación patológica definida por los signos y síntomas que secundarios a la acción de una o varias dosis de un agente tóxico y su evolución puede llevar al sujeto a un estado irreversible e incluso a la muerte. Cada año mueren alrededor de un millón de personas a consecuencia de diversos envenenamientos. La intoxicación alcohólica es causada por alcoholes, compuestos orgánicos que se derivan de los hidrocarburos y están formados por grupos hidroxilos. El etanol es el alcohol que con más frecuencia produce intoxicaciones ya que es el más común y el que más al alcance de la población se encuentra, este produce múltiples alteraciones a nivel del sistema nervioso y de otros sistemas del organismo.

Abstract:Intoxication is considered a pathological manifestation defined by the signs and symptoms secondary to the action of one or more doses of a toxic agent and its evolution may lead to an irreversible subject to state and even to death.Every year about a million people as a result of various poisonings. Alcohol intoxication is caused by alcohols, organic compounds derived hydrocarbons and consist of hydroxyl groups. Ethanol is the alcohol intoxication occurs more frequently because it is the most common and the most accessible to the population is, this results in multiple abnormalities in the nervous system and other body systems.

Development and Validation of a Method for Alcohol Analysis in Brain Tissue by Headspace Gas Chromatography with Flame Ionization Detector.

Ethanol is the most widely used and abused drug. While blood is the preferred specimen for analysis, tissue specimens such as brain serve as alternative specimens for alcohol analysis in post-mortem cases where blood is unavailable or contaminated. A method was developed using headspace gas chromatography with flame ionization detection (HS-GC-FID) for the detection and quantification of ethanol, acetone, isopropanol, methanol and n-propanol in brain tissue specimens. Unfixed volatile-free brain tissue specimens were obtained from the Department of Pathology at Virginia Commonwealth University. Calibrators and controls were prepared from 4-fold diluted homogenates of these brain tissue specimens, and were analyzed using t-butanol as the internal standard. The chromatographic separation was performed with a Restek BAC2 column. A linear calibration was generated for all analytes (mean r2 > 0.9992) with the limits of detection and quantification of 100-110 mg/kg. Matrix effect from the brain tissue was determined by comparing the slopes of matrix prepared calibration curves with those of aqueous calibration curves; no significant differences were observed for ethanol, acetone, isopropanol, methanol and n-propanol. The bias and the CVs for all volatile controls were ≤10%. The method was also evaluated for carryover, selectivity, interferences, bench-top stability and freeze-thaw stability. The HS-GC-FID method was determined to be reliable and robust for the analysis of ethanol, acetone, isopropanol, methanol and n-propanol concentrations in brain tissue, effectively expanding the specimen options for post-mortem alcohol analysis.

Intoxication of a Young Girl Reveals the Pitfalls of GHB Rapid Screening.

The authors discuss the case of a 14-year-old girl who was transferred to the ICU of our hospital with ethanol intoxication (3.3 g/L), loss of consciousness (E5M3V1), and severe amnesia on recovery that was suspected of gamma-hydroxybutyric acid (GHB) intoxication. STAT toxicology screening may be necessary, when sexual assault under GHB intoxication is suspected. Therefore, the initial analysis of a urine sample was performed with a new enzymatic assay analysis for GHB. The enzymatic assay reported a GHB concentration of 26 mg/L, which is above the cut-off value of 10 mg/L. This cut-off value is to differentiate endogenous and exogenous levels because low levels of GHB occur naturally in the body. However, confirmation of these results by gas chromatography, which is common practice to confirm a positive GHB, gave a negative result. This discrepancy is probably contributed to interference of ethanol with the assay. This is a substantial downside of the GHB rapid screening, since the combination of GHB and ethanol is common. It is therefore advised to confirm that the positive GHB results are lower than 50 mg/L by gas chromatography, when using the rapid screening. This way the false-positive results and consequent inappropriate social and legal actions may be avoided.

Prevalence and risk of potentially adverse drug interactions in the treatment of acute alcohol poisoning

ABSTRACT The aim of this paper is to determine the profile of acute alcohol poisoning and to estimate the risk of potentially adverse drug interactions (ADIs) in patients intoxicated by alcohol when attended in emergency care at hospital. A descriptive serial cross-sectional study was performed with 4,271 individuals intoxicated by alcohol, from January 2009 to July 2011. Possible correlations were measured by Pearson's chi-square test. The data show high consumption in the population, especially in males between 25 and 59 years. The main circumstances for poisoning were alcohol misuse (96.3%). After treatment complete recovery from the signs or symptoms of the poisoning was observed in 96.88% cases; and death in 0.70%. The demonstration of potential risk for ADIs in medical care included 300 medical records which contained a history of acute alcohol poisoning. Possible drug-drug interactions (44.2%) and drug-alcohol interactions (55.8%) were demonstrated in 60.60% of analyzed medical records. Among these cases, 3%, 92.4% and 4.6% were classified as mild, moderate and severe, respectively. The measurement of ADIs aims to prevent clinical complications in medical care for alcohol misuse disorders.

RESUMO O objetivo deste trabalho foi definir o perfil de intoxicação alcoólica aguda e estimar o risco de interações medicamentosas adversas (IMAs) potenciais em pacientes com intoxicação alcoólica atendidos na emergência hospitalar. Um estudo descritivo, serial, de corte transversal foi realizado com 4.271 indivíduos com intoxicação alcoólica, de janeiro 2009 a julho 2011. Correlações foram medidas pelo teste qui-quadrado. Os dados mostram alto consumo na população estudada, especialmente em homens de 25 a 59 anos. A principal circunstância de intoxicação foi o abuso (96,3%). Após tratamento, cura foi observada em 96,88% dos casos e morte em 0,7%. O risco de IMAs potenciais no atendimento médico incluiu 300 prontuários médicos com histórico de intoxicação alcoólica aguda. Possíveis interações medicamentosas (44,2%) e interações fármaco-álcool (55,8%) foram observadas em 60,6% dos prontuários analisados. Entre elas, 3%, 92,4% e 4,6% foram classificadas como leve, moderada e grave, respectivamente. A medição das IMAs visa a prevenir complicações clínicas no atendimento dos agravos devido ao abuso de álcool.
