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.

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.

Extremely dilution of strychnos Nux vomica mitigates alcohol-induced reduction in enthalpies associated with free water molecules in a fish brain

Introduction: Alcohol intoxication affects aquaporins in the glial cells of brain resulting in oedema. Nux vomica, a homeopathic drug of plant origin, is known to counteract alcohol effect. The objective of this present study is to find out the level of free water molecules in the brain of a teleost fish under ethanol intoxication. The second objective is to determine whether Nux vomica could restore the level of free water in the alcohol treated fish. Materials and methods: One group of fish was exposed to 456 mM ethanol for 30 min, another exposed first to a solution of Nux vomica 200c for 20 min and then to 456 mM ethanol for 30 min. The third group served as an untreated control. The mid brain of each fish was kept in an aluminium sample pan and its free water level was assessed by differential scanning calorimetry (DSC). Results: All alcohol treated fish showed significant reduction in the level of free water molecules as compared to the untreated control. Treatment with Nux vomica increased the level of free water in the brain significantly as compared to the untreated alcoholic group. Conclusion: Alcohol intoxication reduces free water molecules in the fish brain. Nux vom might have acted on aquaporins in the glial cells thereby increasing the level of free water in the brain.

Mixed isopropanol-methanol intoxication following ingestion of alcohol-based hand rub solution
.

Traditionally, ingestion of alcohol-based hand rub solution results in isopropanol poisoning, which has a low toxicity. We describe a case of combined methanol and isopropanol intoxication by ingestion of alcohol-based hand rub solution. Metabolic acidosis was absent in our patient, presumably because formic acid production is blocked by isopropanol, which inhibits alcohol dehydrogenase. Our case highlights the importance of considering methanol intoxication in patients who ingested alcohol-based hand rub solution, even when there is no metabolic acidosis, and timely removal of the toxic alcohols by dialysis in these patients would prevent permanent retinal damage.

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.

[Psychosocial Characteristics of Adolescents Treated for Alcohol Intoxication in Emergency Departments]. / Psychosoziale Merkmale von Jugendlichen, die wegen einer Alkoholintoxikation im Krankenhaus behandelt wurden.

Psychosocial Characteristics of Adolescents Treated for Alcohol Intoxication in Emergency Departments In Germany, every year a substantial number of adolescents is treated in emergency departments for acute alcohol intoxication. Until now, only few studies have been published investigating psychosocial aspects in this group of adolescents. In the present study 316 adolescents were surveyed in the emergency department regarding their problematic use of alcohol and illicit drugs, their patterns of alcohol consumption, their alcohol-related and mental problems. We reported results for the whole sample. Additionally, the sample was divided in two groups based on the result in an established screening instrument for problematic alcohol use (CRAFFT-d). To compare the two groups we conducted unpaired t tests, chi-square tests and logistic regression analyses. Compared to the other group the adolescents exceeding the cut-off value of the CRAFFT-d reported a statistically significant higher past 30-day binge drinking frequency and number of standard-drinks consumed on a typical drinking occasion, more alcohol-related problems, more frequently a problematic use of illicit drugs and more mental problems (regarding antisocial behavior, anger control problems and self-esteem). Antisocial behavior was the most important factor for the affiliation to one of the two groups. The application of the screening instrument for problematic alcohol use (CRAFFT-d) in the emergency department seems to be a promising approach to identify adolescents with a general higher psychosocial burden.

Women and Men Admitted for Alcohol Intoxication at an Emergency Department: Alcohol Use Disorders, Substance Use and Health and Social Status 7 Years Later.

AIMS: To assess the prevalence of alcohol use disorder (AUD), substance use, mental health and social status 7 years following an Emergency Department (ED) admission for alcohol intoxication. To assess gender differences in these prevalences. METHODS: Cohort of 631 patients aged 18-30 years admitted for alcohol intoxication in 2006-2007 at a tertiary referral hospital in Switzerland, contacted for an interview in 2014. Assessment consisted of demography, Alcohol Use Disorders Identification Test-Consumption, Mini International Neuropsychiatric Interview for AUD, Patient Health Questionnaire (depression, anxiety) and lifetime/past year use of tobacco/illegal drugs. Gender differences were assessed with Chi-square tests, t-tests and Wilcoxon tests. RESULTS: In 2014, 318/631 (50.4%) completed the interview. Study completers were not different from non-completers on baseline characteristics (all P > 0.2). Of study completers, 36.8% were unemployed, 56.9% reported hazardous alcohol use, 15.1% alcohol dependence, 13.2% harmful use, 18.6% depression, 15.4% anxiety disorder. Prevalence of any use (lifetime/past year) was 93.4%/80.2% for tobacco, 86.6%/53.1% for cannabis, 54.7%/22.6% for cocaine, 25.6%/13.5% for sedatives, 40.9%/11.0% for stimulants, 21.7%/7.2% for opioids. Men reported significantly more binge drinking, AUD, cannabis use (past year) and more lifetime cannabis, cocaine and stimulants use (all P < 0.05). There was no gender difference in the prevalence of hazardous alcohol use and tobacco use. The prevalence of psychiatric disorders was significantly higher in women (P < 0.05). CONCLUSIONS: Seven years after being admitted for alcohol intoxication, young patients are likely to present substance misuse, mental health disorders and social problems, suggesting  that they should be offered secondary prevention measures while in the ED. SHORT SUMMARY: We studied a cohort of patients aged 18-30 and admitted for alcohol intoxication in 2006-2007 at a tertiary hospital. Participants were interviewed in 2014. Seven years after an admission for alcohol intoxication, patients are likely to present AUDs, substance misuse, mental health disorders and social problems.

Long-term outcomes after adolescent in-patient treatment due to alcohol intoxication: A control group study.

BACKGROUND: The long-term psychosocial development of adolescents admitted to in-patient treatment with alcohol intoxication (AIA) is largely unknown. METHODS: We invited all 1603 AIAs and 641 age- and sex-matched controls, who had been hospitalized in one of five pediatric departments between 2000 and 2007, to participate in a telephone interview. 277 cases of AIA and 116 controls (mean age 24.2 years (SD 2.2); 46% female) could be studied 5-13 years (mean 8.3, SD 2.3) after the event. The control group consisted of subjects who were admitted due to conditions other than alcohol intoxication. Blood alcohol concentration on admission was systematically measured in the AIA but, owing to the retrospective study design, not in the control group. Subtle alcohol intoxication could therefore not be entirely ruled out in the control group. Long-term outcome measures included current DSM-5 alcohol use disorders (AUD), drinking patterns, illicit substance use, regular smoking, general life satisfaction, use of mental health treatment, and delinquency. RESULTS: AIA had a significantly elevated risk to engage in problematic habitual alcohol use, to exhibit delinquent behaviors, and to use illicit substances in young adulthood compared to the control group. Severe AUD also occurred considerably more often in the AIA than the control group. CONCLUSIONS: In the majority of AIAs, further development until their mid-twenties appears to be unremarkable. However, their risk to develop severe AUD and other problematic outcomes is significantly increased. This finding calls for a diagnostic instrument distinguishing between high- and low-risk AIAs already in the emergency room.

The effect on problematic drinking behavior of a brief motivational interview shortly after a first arrest for driving under the influence of alcohol: a randomized trial.

BACKGROUND: In medical settings, motivational interviewing-based "brief intervention" (BI) counseling reduces alcohol-related risk-taking behavior and harm in high-risk populations. Individuals arrested for driving under the influence of alcohol (DUI) are another at-risk population. We sought to determine whether a BI administered shortly after a first DUI arrest might decrease problematic drinking behavior. METHODS: We conducted a single-center, parallel-group, double-blinded superiority randomized trial (NCT01270217), enrolling first-time DUI arrestees at a county jail from December 2010 through April 2011. Before their release, we randomized participants by computer-generated sequence to either a single BI or no discussion. We assessed 90-day change in Alcohol Use Disorders Identification Test (AUDIT) scores (range 0-40, higher values indicating more problematic drinking) as the primary outcome. RESULTS: We enrolled 200 subjects (100 to each arm), and 181 (90.5%, 86 control and 95 BI) completed the 90-day follow-up. Mean (SD) age was 30 (10) years, and 50% were men. Mean (SD) blood alcohol concentration upon arrest was 0.14% (0.04%). Mean (SD) baseline AUDIT scores were 8.8 (5.8) among control subjects and 7.7 (6.3) among BI subjects. At 90 days, AUDIT scores decreased by a mean (SD) 4.7 (5.1) units among control subjects and 3.4 (5.0) among BI subjects (difference, -1.3; 95% confidence interval [CI], -2.8 to +0.1). The likelihood of subsequent binge drinking [relative risk (RR) 1.6; 95% CI, 0.8-3.0; BI vs. control], abstinence (RR, 0.9; 95% CI, 0.4-2.1), alcohol-related injury to self or others (RR, 0.4; 95% CI, 0.1-2.4), and seeking treatment (RR, 1.2; 95% CI, 0.8-1.7) did not differ. CONCLUSION: A single BI counseling session shortly after first-time DUI arrest does not reduce 90-day self-reported drinking behavior or increase seeking treatment for drinking beyond that which occurs without such a discussion. LEVEL OF EVIDENCE: Therapeutic study, level III.

Rabdomiolisis secundaria a intoxicación etílica: caso clínico / Rhabdomyolysis following alcohol intoxication: a case report

Introduction: rhabdomyolysis is a potentially lethal syndrome characterized by disintegration of striated muscle fibers. In children Rhabdomyolysis is caused mostly by trauma, nonketotic hyperosmolar coma, viral myositis, dystonia and malignant hyperthermia. Case report: a 14 year old male was brought into the emergency room because of a decreased level of consciousness following alcohol and cannabis. An initial assessment indicated the presence of hypothermia and a Glasgow Coma Scale of 9. A blood biochemical analysis showed a mixed acidosis and CPK levels of 12260 U/L (CK-MB 132 U/L). After diagnosing alcohol induced coma and rhabdomyolysis, intravenous fluids and urinary alkalinization are administered. The patient presented a rapid neurological improvement reaching normal within 12 hours. He remained normotensive, adequate diuresis, negative balances, normal blood gas values and urine test strips presented no pathological changes. A maximum level of serum CPK was observed 24 hours after ingestion (20820 U/L), with subsequent decline to 6261 U/L at day 5, once he was discharged. Discussion: alcohol poisoning is a rare cause of rhabdomyolysis in pediatrics. The main therapeutic goal is to prevent acute renal failure, aggressive fluid therapy and urine alkalinization then must be administered, monitoring possible electrolyte abnormalities and the presence of myoglobinuria. In conclusion, rhabdomyolysis is one of the possible complications after alcohol poisoning. Given its potential morbidity, it should always be considered.

Introducción: la rabdomiolisis es un síndrome potencialmente letal caracterizado por la destrucción de fibras musculares estríadas. En niños es producido fundamentalmente por traumatismos, coma hiperosmolar no cetósico, miositis vírica, distonía o hipertermia maligna. Caso clínico: varón de 14 años que es traído al servicio de Urgencias por disminución del nivel de conciencia secundaria a consumo de alcohol y cannabis. En la valoración inicial en nuestro centro se constatan hipotermia y una puntuación según la escala de Glasgow de 9. En el análisis bioquímico sanguíneo destacan una acidosis mixta y niveles de CPK de 12.260 U/L (CK-MB 132 U/L). Con los diagnósticos de coma etílico y rabdomiolisis se inicia administración de fluidoterapia intravenosa y alcalinización urinaria. Presentó una rápida mejoría neurológica con normalización en las primeras 12 h. Se mantuvo normotenso, con adecuada diuresis, balances negativos, normalización de los valores gasométricos y tiras reactivas de orina seriadas sin hallazgos patológicos. Se objetivó un nivel máximo de CPK sérica 24 h tras la ingesta (20.820 U/L), con descenso posterior hasta 6.261U/L a los 5 días, cuando se dio de alta. Discusión: la intoxicación etílica constituye una causa infrecuente de rabdomiolisis en pediatría. El principal objetivo terapéutico es evitar el fracaso renal agudo, por lo que se deben iniciar fluidoterapia agresiva y eventual alcalinización de la orina, manteniendo monitorizados las posibles alteraciones electrolíticas así como la presencia de mioglobinuria. En conclusión, la rabdomiolisis es una de las posibles complicaciones de la intoxicación etílica. Dada su potencial morbimortalidad, siempre debe ser tenida en cuenta.

Hypertonic saline resuscitation enhances blood pressure recovery and decreases organ injury following hemorrhage in acute alcohol intoxicated rodents.

BACKGROUND: Acute alcohol intoxication (AAI) impairs the hemodynamic and arginine vasopressin (AVP) counter-regulation to hemorrhagic shock (HS) and lactated Ringer's solution (LR) fluid resuscitation (FR). The mechanism of AAI-induced suppression of AVP release in response to HS involves accentuated nitric oxide (NO) inhibitory tone. In contrast, AAI does not prevent AVP response to increased osmolarity produced by hypertonic saline (HTS) infusion. We hypothesized that FR with HTS during AAI would enhance AVP release by decreasing periventricular nucleus NO inhibitory tone, subsequently improving mean arterial blood pressure (MABP) and organ perfusion. METHODS: Male Sprague-Dawley rats received a 15-hour alcohol infusion (2.5 g/kg + 0.3 g/kg/h) or dextrose (DEX) before HS (40 mm Hg × 60 minutes) and FR with HTS (7.5%, 4 ml/kg) or LR (2.4 × blood volume removed). Organ blood flow was determined, and brains were collected for NO content at 2 hours after FR. RESULTS: HTS improved MABP recovery in AAI (109 vs. 80 mm Hg) and DEX (114 vs. 83 mm Hg) animals compared with LR. This was associated with higher (>60%) circulating AVP levels at 2 hours after FR compared with those detected in LR animals in both groups. Neither AAI alone nor HS in DEX animals resuscitated with LR altered organ blood flow. In AAI animals, HS and FR with LR reduced blood flow to the liver (72%), small intestine (65%), and large intestine (67%) compared with shams. FR with HTS improved liver (threefold) and small intestine (twofold) blood flow compared with LR in AAI-HS animals. The enhanced MABP response to HTS was prevented by pretreatment with a systemic AVP V1a receptor antagonist. HTS decreased periventricular nucleus NO content in both groups 2 hours after FR. CONCLUSION: These results suggest that FR with HTS in AAI results in the removal of central NO inhibition of AVP, restoring AVP levels and improving MABP and organ perfusion in AAI-HS.

Ethylene glycol ingestion masked by concomitant ethanol intoxication.

An obtunded male with a history of alcohol abuse presented to the emergency department with metabolic acidosis, an osmolar gap and lactic acidosis. The patient was initially treated for alcohol intoxication due to an extremely high blood alcohol level. Following respiratory failure and intubation, a large volume of dark green liquid was removed via nasogastric suction; bedside fluorescence for ethylene glycol was negative. Twenty-four hours later, the patient's glomerular filtration rate decreased significantly, serum osmolality was 807, the osmolar gap was 407, complete metabolic panel showed pH of 6.8, sodium of 156 mmol/l, potassium of 7.3 mmol/l, chloride of 116, CO(2) of 3.9 and anion gap of 30.7. Blood lactic acid was >56 mmol/l. The patient received emergency haemodialysis. Four days after presentation, the patient began to respond to voice commands and was extubated. Currently, the patient still receives haemodialysis due to ongoing renal failure, but no long-term neurologic complications are evident.

Acute ethanol intoxication and the trauma patient: hemodynamic pitfalls.

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

Interpersonal violence and facial fractures.

PURPOSE: Interpersonal violence is a major health hazard that contributes to the high volume of trauma seen in the emergency department. It is also one of the principal causes of maxillofacial fractures. MATERIALS AND METHODS: The present study was a retrospective analysis of patients referred to, and treated at, the Oral and Maxillofacial Surgery Unit at Christchurch Hospital during an 11-year period (1996 to 2006). The variables examined included patient demographics, fracture types, mode of injury, and treatment delivered. RESULTS: An increase was found in the number of fractures due to interpersonal violence in the second half of the study, although the proportion remained the same. The age of the patients ranged from 9 to 89 years (mean 28). The male-to-female ratio was 9:1. Of the patients, 87% had alcohol involvement. The mandible was the most common site of fracture, followed by the zygoma. Other midface fractures, including Le Fort fractures, were less frequently observed. Of the patients, 59% were hospitalized and 56% required surgery, with internal fixation necessary in 41% of patients. CONCLUSION: An increase occurred in the number of facial fractures associated with interpersonal violence during the study period. Young male adults were the most affected demographic group, with alcohol a main contributing factor. Violence-related facial fracture is a health hazard that deserves more public awareness and implementation of preventive programs.

Process evaluation of serial screening criteria to identify injured patients that benefit from brief intervention: practical implications.

BACKGROUND: The aim of the current study is to evaluate the effectiveness of serial screening methods for the identification of injured patients at risk for alcohol problems and are most likely to benefit from brief interventions. We hypothesize that blood alcohol concentration (BAC) alone is not sufficient to effectively identify at-risk drinkers in the trauma care setting. METHODS: During a 2-year period, patients admitted to an urban Level I trauma center for treatment of an injury were screened for alcohol problems. Screening consisted of four serial screening criteria: (1) clinical indication of acute intoxication including positive BAC; (2) self-reported drinking 6 hours before injury; (3) at-risk drinking as defined by National Institutes on Alcohol Abuse and Alcoholism or (4) by responding yes to one or more items on the CAGE within the last year. RESULTS: In all, 11,028 patients were seen. Fifty-eight percent were eligible for screening and 90% of eligible patients were screened. Of screened patients, 41% screened positive for an alcohol-related injury. Of patients that did not have a BAC drawn, 39% (n = 935) went on to screen positive using serial screening procedures. Additionally, 36% (n = 339) of patients with a negative BAC went on to screen positive using serial screening procedures. CONCLUSIONS: This evaluation clearly suggests that BAC alone is not sufficient to identify patients who are most likely to benefit from brief alcohol interventions. Self-reported drinking in conjunction with BAC facilitates identification and intervention of injured patients with alcohol problems.

Drunken patients in the general hospital: their care and management.

In Britain alcohol consumption is increasing, 1 in 4 men and 1 in 10 women drink hazardously, 1 in 3 young men, and 1 in 4 young women regularly binge drink. Mortality rates attributable to alcohol have doubled; with 1 in 5 male inpatients having an alcohol related problem. The increasing problem of managing drunken behaviour in accident and emergency departments is discussed. Although an alcohol history is recommended for all admissions, because of various reasons, hazardous drinkers continue to miss the opportunity of effective interventions. In addition to the more formal treatments for alcohol problems, there is a wealth of evidence reporting the effectiveness of brief interventions carried out by a range of health professionals can lead to long term reductions in alcohol consumption. This review discusses practical and legal issues of the assessment, screening tools, and management of intoxicated patients.

Treatment of the alcohol intoxications: ethylene glycol, methanol and isopropanol.

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.
