ABSTRACT
INTRODUCTION: Acute alcohol toxicity is a significant component of alcohol-related mortality. The study aimed to: (i) determine the circumstances of death and characteristics of fatal alcohol toxicity cases, 2011-2022; (ii) determine their toxicological profile and major autopsy findings; and (iii) determine trends in population mortality rates. METHODS: Retrospective study of acute alcohol toxicity deaths in Australia, 2011-2022, retrieved from the National Coronial Information System. RESULTS: A total of 891 cases were identified, with a mean age of 49.2 years, 71.0% being male. Alcohol use problems were noted in 71.3%. In 57.5% death was attributed solely to acute alcohol toxicity, and combined acute alcohol toxicity/disease in 42.5%. There was evidence of sudden collapse in 24.9% of cases. The mean BAC was 0.331 g/100 mL (range 0.107-0.936), and spirits were the most commonly reported beverages (35.8%). Cases of combined toxicity/disease had significantly lower BACs than those attributed solely to alcohol toxicity (0.296 vs. 0.358 g/100 mL). Cardiomegaly was diagnosed in 32.5%, and severe coronary artery disease in 22.1%. Aspiration of vomitus was noted in 18.0%, and chronic obstructive pulmonary disease in 19.6%. Severe liver steatosis was present in 33.4% and 13.6% had cirrhosis. There was an average annual percentage increase in deaths of 7.90. DISCUSSION AND CONCLUSIONS: The 'typical' case was a long-standing, heavy spirits drinker. BACs showed enormous variation and no arbitrary concentration may be deemed lethal. Clinically significant disease was associated with death at a lower BAC and people with such disease may be at increased risk of alcohol poisoning.

Ethylene glycol (EG), in addition to its neurotoxic and nephrotoxic effects, evokes oxidative stress. The aim of this study was to assess the influence of the ethylene glycol on the biochemical indicators and oxidoreductive balance of patients treated for acute poisoning. The total study group consisted of 56 persons including 26 alcoholics who took EG as a substitute for ethyl alcohol in the course of alcohol dependence syndrome and 30 controls. Severity of poisoning, results of acid-base parameters, biochemical, and toxicological tests as well as biomarkers of the oxidative stress in blood were analyzed during the patients' hospitalization. The key issue was to assess the oxidative stress and biochemical disturbances caused by EG and the type of treatment applied in the course of poisoning. Significant changes in some parameters were found both at time of diagnosis and after treatment initiation (ethanol as an antidote and hemodialysis). The most important differences included the activity of hepatic parameters (aspartate aminotransferase, AST) and oxidative stress markers like catalase (CAT); correlation of the lipid peroxidation products level (TBARS) with urea concentration has been shown. On the last day of the hospitalization, in some cases, the mutual correlation between the evaluated markers were observed, for example, between alanine transaminase (ALT) and glutathione reductase (GR), and urea concentration and glutathione level (GSH/GSSG). The concentration of ions (H+) had a major impact on the oxidoreductive balance, correlating with the elevated GR and GSH/GSSG levels.

OBJECTIVE: Investigate whether there are differences in the drugs involved, symptomatology and severity of drug intoxication in patients with co-ingestion of alcohol attended in hospital emergency departments (ED). METHOD: Patients attended in 11 Spanish EDs due to drug intoxication were included. Sociodemographic and clinical characteristics were collected. A combined adverse event of cardiorespiratory arrest, need for intubation, and admission to intensive care or death was considered as the primary indicator of severity. The symptomatology and severity were compared adjusted for age, sex and type of drug based on whether or not ethanol had been co-ingested. RESULTS: 3925 patients (alcohol co-ingestion: 2290, 58.3%) with a mean age of 33 (±11) years were included, and 25% were women. Co-ingestion of alcohol was observed in younger patients, in EDs in areas with high leisure tourism, on holidays and during the early morning hours. It was also more frequent in individuals intoxicated by amphetamine derivatives (66.2%) and cocaine (65.7%), and was more frequently associated with a reduction in consciousness (odds ratio [OR] = 2.13, 95% confidence interval [CI] 1.69-2.67) and agitation/aggressiveness (OR = 1.22, 95% = 1.04-1.43). A combined adverse event was observed in 114 patients (2.9%) with no differences between individuals co-ingesting or not ethanol (3.1% vs. 2.7%; OR = 1.11, 95% CI = 0.74-1.65). CONCLUSION: Co-ingestion of alcohol is more frequent in individuals intoxicated by cocaine and amphetamines and predisposes a greater reduction in the level of consciousness or agitation, although there are no differences in the severity of the episodes of drug intoxication.

Fatal intoxications are common in a medico-legal autopsy setting and are associated with sparse findings during autopsy. It has been suggested that an increased lung weight may be associated with such fatalities. Previous literature is generally limited to a descriptive approach, including only opioid deaths, and lacking a definition of "heavy" lungs. Our aim was to create a model to identify cases with heavy lungs and to assess the predictive power of "heavy" lungs in identifying cases of different types of fatal intoxications during autopsy in an unselected medico-legal autopsy population. We identified all medico-legal autopsy cases ≥18 years in Sweden from 2000 through 2013. The lung weight to heart weight (LWHW) ratio was calculated. The positive predictive values (PPV) and negative predictive values (NPV) of both lung weight and LWHW ratio were calculated. Mean lung weight was higher in the intoxication group but the predictive power in the individual case was limited. Lung weight to heart weight ratio had better predictive power than lung weight alone, with a PPV of at most 0.15(0.14, 0.16 95% CI), while the NPV was 0.96 (0.95, 0.96 95% CI). The association between fatal intoxication and increased lung weight was positive, regardless of method and cutoffs used. While the PPV was poor, the NPV could reduce suspicion of fatal intoxication in the absence of other information. LHWH ratio is only a probability factor for fatal intoxication; accurate cause of death determination-as always-requires consideration of circumstances, autopsy, and toxicologic findings.

Importance: Persons with opioid use disorder (OUD) and co-occurring alcohol use disorder (AUD) are understudied and undertreated. It is unknown whether the use of medications to treat OUD is associated with reduced risk of alcohol-related morbidity. Objective: To determine whether the use of OUD medications is associated with decreased risk for alcohol-related falls, injuries, and poisonings in persons with OUD with and without co-occurring AUD. Design, Setting, and Participants: This recurrent-event, case-control, cohort study used prescription claims from IBM MarketScan insurance databases from January 1, 2006, to December 31, 2016. The sample included persons aged 12 to 64 years in the US with an OUD diagnosis and taking OUD medication who had at least 1 alcohol-related admission. The unit of observation was person-day. Data analysis was performed from June 26 through September 28, 2020. Exposures: Days of active OUD medication prescriptions, with either agonist (ie, buprenorphine or methadone) or antagonist (ie, oral or extended-release naltrexone) treatments compared with days without OUD prescriptions. Main Outcomes and Measures: The primary outcome was admission for any acute alcohol-related event defined by International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes. Conditional logistic regression was used to compare OUD medication use between days with and without an alcohol-related event. Stratified analyses were conducted between patients with OUD with and without a recent AUD diagnostic code. Results: There were 8â¯424â¯214 person-days of observation time among 13â¯335 participants who received OUD medications and experienced an alcohol-related admission (mean [SD] age, 33.1 [13.1] years; 5884 female participants [44.1%]). Agonist treatments (buprenorphine and methadone) were associated with reductions in the odds of any alcohol-related acute event compared with nontreatment days, with a 43% reduction for buprenorphine (odds ratio [OR], 0.57; 95% CI, 0.52-0.61) and a 66% reduction for methadone (OR, 0.34; 95% CI, 0.26-0.45). The antagonist treatment naltrexone was associated with reductions in alcohol-related acute events compared with nonmedication days, with a 37% reduction for extended-release naltrexone (OR, 0.63; 95% CI, 0.52-0.76) and a 16% reduction for oral naltrexone (OR, 0.84; 95% CI, 0.76-0.93). Naltrexone use was more prevalent among patients with OUD with recent AUD claims than their peers without AUD claims. Conclusions and Relevance: These findings suggest that OUD medication is associated with fewer admissions for alcohol-related acute events in patients with OUD with co-occurring AUD.

The incidence of acute poisonings has increased in recent years and constitutes approximately 2% of the services provided by the Emergency Department currently. The objective of this study is to describe the frequency and characteristics of the intoxications treated at the Central University Hospital of Asturias during 2015 from biochemical-analytical, epidemiological and medical-legal perspectives. We conducted a retrospective study and a descriptive analysis of the clinical and sociodemographic variables included in the acute intoxication (AI) protocol at the national level. This hospital treated 2,478 cases of acute poisoning, representing 2.3% of the emergencies treated and corresponding to an incidence of 764 cases/100,000 inhabitants/year with an age ranging from under 1 year to over 80 years. The average age of the patients was 43.6 (SD = 16.6) years. Of these patients, 59.4% were males with an average age of 44 (SD = 16.8) years, and women represented 43.1% with an average age of 42.8 (SD = 16.5) years. These intoxications have a frequency of 47.2% during the weekend, while 37.4% occur between June and September. Acute voluntary intoxication is the most frequent intentionality, corresponding to 83.2% of the cases. We must point out that the medical records register 16.8% of the cases as suicide attempts. Ethanol and benzodiazepines are the most commonly-used toxics. These intoxications are treated in the Emergency Department without requiring hospitalization and have a very low mortality rate.
La incidencia de las intoxicaciones agudas ha aumentado en los últimos años, y actualmente constituye aproximadamente el 2% de las atenciones sanitarias llevadas a cabo por los Servicios de Urgencias. El objetivo de este estudio es describir la frecuencia y características de las intoxicaciones atendidas en el Hospital Universitario Central de Asturias durante el año 2015 desde la perspectiva bioquímica-analítica, epidemiológica y médico-legal. Se realizó un estudio retrospectivo y un análisis descriptivo de las variables clínicas y sociodemográficas incluidas en el protocolo de intoxicación aguda a nivel nacional. Este hospital atendió 2478 casos de intoxicaciones agudas representando el 2,3% de las urgencias atendidas y que corresponde a una incidencia de 764 casos/100000 habitantes/año con un rango de edad de menores de 1 año a mayores de 80 años. La edad media de los pacientes atendidos fue de 43,6 (DE = 16,6) años. El 59,4% de los pacientes eran varones con una edad media de 44 (DE = 16,8) años, las mujeres representaban el 43,1% y su edad media era de 42,8 (DE = 16,5) años. El 47,2% de estas intoxicaciones ocurren durante el fin de semana y el 37,4% se dan entre junio y septiembre. La intencionalidad más frecuente es la intoxicación aguda voluntaria correspondiente al 83,2% de los casos. Cabe destacar que el 16,8% de los casos están referenciados en su historia clínica como intentos de suicidio. Los tóxicos más empleados son el etanol y las benzodiacepinas. Estas intoxicaciones son resueltas en el Servicio de Urgencias sin requerir ingreso hospitalario y poseen una tasa de mortalidad muy baja.

BACKGROUND: Case studies and small series have demonstrated that beverage ethanol may pose a serious poisoning hazard to infants. Intoxicated infants may not present with the classic signs or symptoms of ethanol poisoning. The objective of this study was to describe the epidemiology of beverage ethanol exposures among infants reported to the United States poison control centers. METHODS: Data from the National Poison Data System were retrospectively analyzed for infants <12 months of age who were exposed to beverage ethanol from 2009-2018. RESULTS: Over the 10-year study period, 1,818 infant exposures to beverage ethanol were reported. Most exposures were single substance (95.2%), and the most common route of exposure was ingestion (n = 1,738). Infants 9-11 months were the most commonly exposed age group subset (45.3%). The annual number and rate of alcoholic beverage exposure increased by 37.5% and 42.9%, respectively, from 2009 to 2018. Of the 563 infants evaluated at a healthcare facility, 38% of exposures were hospitalized. Infants 0-5 months of age had higher odds of being admitted to a non-critical (OR: 2.35, 95% CI: 1.41-3.92) or critical care unit (OR: 2.39; 95% CI: 1.50-3.79) compared to infants 6-11 months of age. Infants 0-5 months of age were more likely to (OR: 4.65; 95% CI: 3.18-6.79) experience a serious outcome compared to infants ages 6-11 months. Five fatalities in infants <6 months old were documented. An in-depth case review identified improper storage and subsequent formula preparation with beverage ethanol as a common exposure mechanism. CONCLUSIONS: Beverage ethanol exposures among infants are associated with hospitalization, serious clinical effects, and mortality. Infants may present with atypical signs and symptoms of intoxication, requiring a high index of suspicion. Opportunities exist to reduce exposures by addressing improper storage of beverage alcohols.

BACKGROUND: Buprenorphine is abused in several countries notwithstanding its benefits as an analgesic and as an opioid agonist treatment medication. Benzodiazepines and alcohol have previously been associated with buprenorphine toxicity. This study elucidates the role of emerging concomitant drugs in different groups of buprenorphine user deaths. METHODS: All cases in the Finnish national post-mortem toxicology database from 2016-2019 in which buprenorphine or norbuprenorphine was a laboratory finding in any post-mortem specimen and age at death of 15-64 years were investigated for cause and manner of death, concurrent drug and alcohol findings, age, and gender. RESULTS: There were 792 deaths with a buprenorphine finding, of which buprenorphine was implicated in poisoning without other opioids in 271 cases (34 %). In this group of buprenorphine poisoning deaths, concomitant benzodiazepines were found in 94 % (clonazepam 53 %), illicit drugs in 63 %, gabapentinoids in 50 % (pregabalin 41 %), alcohol in 41 %, antidepressants in 32 %, and antipsychotics in 28 % of cases; only three deaths showed no benzodiazepines, alcohol, or gabapentinoids. Polydrug use was common regardless of the cause of death. In the age group 15 to 24 years, concomitant use of benzodiazepines and illicit drugs, and buprenorphine poisoning were more prevalent than in the age group 25-64 years. CONCLUSIONS: The unprecedentedly high concomitant use of benzodiazepines in buprenorphine user deaths obscures other possible pharmacological risk factors for buprenorphine poisoning that could be relevant for prevention. Higher mortality in the younger age group suggests particularly unsafe drug use patterns that should be addressed.

RESUMO Objetivo. Descrever o perfil toxicológico de todas as vítimas de suicídio no Rio Grande do Sul, Brasil, de 2017 a 2019. Métodos. Neste estudo descritivo e transversal, foram consultados todos os laudos periciais e as ocorrências policiais relacionados aos óbitos por suicídio no estado. Foram realizadas análises de correspondência múltipla e construídos modelos independentes de regressão logística, tendo como variáveis dependentes o etanol, os ansiolíticos, os antidepressivos, as substâncias ilícitas e os agentes tóxicos não medicamentosos. Resultados. Foram realizados 2 978 exames de alcoolemia, com resultado positivo em 28,5%. A chance de resultados positivos para alcoolemia foi 0,5 (IC95%: 1,1 a 2,2) vez maior para suicídio durante a noite, 1,0 (IC95%: 1,4 a 2,9) vez maior para suicídio aos finais de semana e 0,9 (IC95%: 1,3 a 2,7) vez maior na presença de antecedentes criminais. A pesquisa de psicotrópicos (2 900 amostras) detectou algum medicamento em 30,4%. Os ansiolíticos foram a classe mais frequente, com chance 1,5 (IC95%: 1,6 a 4,1) vez maior em mulheres e 0,8 (IC95%: 1,2 a 2,7) vez maior para suicídios ocorridos no outono-inverno. As substâncias ilícitas (n = 338) tiveram chance 4,1 (IC95%: 1,9 a 14,4) vezes maior de detecção na macrorregião de Pelotas em relação à de Passo Fundo e 1,2 (IC95%: 1,3 a 3,6) vez maior em pessoas com resultados positivos para etanol. Não houve diferença significativa entre adolescentes e adultos. Conclusões. Embora sem evidência de causalidade, os resultados mostram um vínculo entre o suicídio e diversos psicoativos. Os médicos legistas devem ser orientados quanto à necessidade de realização de exames toxicológicos em todos os casos de suicídio.
ABSTRACT Objective. To describe the toxicology of suicide cases recorded in the state of Rio Grande do Sul, Brazil, from 2017 to 2019. Method. The present descriptive, cross-sectional study examined all the medico-legal reports and police records related to suicide deaths in the state. Multiple correspondence analyses were performed along with independent logistic regression models having ethanol, anxiolytic and antidepressant drugs, illicit drugs, and non-medical substances as dependent variables. Results. Ethanol was investigated in 2 978 samples, with positive results in 28.5%. The odds of a positive ethanol finding were 0.5 time higher (95%CI: 1.1; 2.2) for suicides occurring at night, 1.0 (95%CI: 1.4; 2.9) time higher for suicides occurring on weekends, and 0.9 (95%CI: 1.3; 2.7) time higher in individuals with a prior criminal record. Investigation of psychotropic drugs (2 900 samples) was positive in 30.4% samples. Anxiolytics were the most common medication detected, with 1.5 (95%CI: 1.6; 4.1) time higher odds of occurrence in women and 0.8 time higher odds (95%CI: 1.2; 2.7) for suicides occurring in the fall-winter. The odds of detecting illicit drugs (n = 338) were 4.1 times higher (95%CI: 1.9; 14.4) in the regions of Pelotas (south of the state) vs. Passo Fundo (north), and 1.2 (95%CI: 1.3; 3.6) time higher in cases with positive ethanol results, without significant difference between adolescents and adults. Conclusions. Despite the lack of evidence on causality, the present results support a link between suicide and several psychoactive drugs. Medico-legal experts should be guided regarding the need to perform toxicological tests in all suicide cases.

En este estudio descriptivo y transversal se consultaron todos los informes periciales y policiales sobre las muertes por suicidio en el estado. Se realizaron análisis de correspondencia múltiple y se crearon modelos independientes de regresión logística, con empleo de etanol, productos ansiolíticos y antidepresivos, sustancias ilícitas y agentes tóxicos no medicamentosos como variables dependientes. Resultados. Se realizaron 2 978 exámenes de alcoholemia, con resultado positivo en un 28,5%. La probabilidad de obtener resultados positivos para alcoholemia aumentó 0,5 (IC95%: 1,1-2,2) en casos de suicidio durante la noche, 1,0 (IC95%: 1,4-2,9) en casos de suicidio en los fines de semana y 0,9 (IC95%: 1,3-2,7) cuando había antecedentes penales. En la investigación de productos psicotrópicos (2 900 muestras) se detectó algún medicamento en un 30,4%. Los ansiolíticos fueron la clase detectada con más frecuencia, con un aumento de la probabilidad de 1,5 (IC95%: 1,6-4,1) en las mujeres y de 0,8 (IC95%: 1,2-2,7) en casos de suicidio durante el otoño y el invierno. El aumento de la probabilidad de detección de sustancias ilícitas (n = 338) fue de 4,1 (IC95%: 1,9-14,4) en la macrorregión de Pelotas en comparación con la de Passo Fundo y de 1,2 (IC95%: 1,3-3,6) en personas con resultados positivos en la prueba de detección de etanol, sin que hubiera ninguna diferencia significativa entre adolescentes y adultos. Conclusiones. Aun sin haberse comprobado la causalidad, los resultados muestran que existe un vínculo entre el suicidio y diversos productos psicoactivos. Es preciso orientar a los médicos legistas con respecto a la necesidad de realizar exámenes toxicológicos en todos los casos de suicidio.

AIM: To describe the context surrounding the deaths of homeless people in New Zealand and to determine the proportion of deaths that could be considered amenable to healthcare. METHOD: We used coroners' findings related to 171 deaths of persons with "no fixed abode" at the time of death, from 2008 to 2019. Recent lists of amenable mortality from the New Zealand Ministry of Health and the Office of National Statistics in the UK were combined to determine the rate of amenable mortality. RESULTS: The life expectancy of homeless persons identified in this sample was 30 years shorter than in the housed population, with a mean age of death of 45.7 years. Deaths occurred mainly alone, in public spaces (56.1%) or in private vehicles (14%). Three-quarters (75.8%) of homeless persons died from conditions amenable to timely and effective healthcare interventions, mostly from natural causes (45.7%) and suicide (41.5%). CONCLUSION: Homeless people experience considerable challenges when accessing the healthcare system, as uncovered by the dramatic rate of amenable mortality. Our findings highlight the urgent need to implement specific models of care that are designed to meet the social and healthcare needs of homeless persons and address the significant health inequalities they experience.

BACKGROUND: Most people are frequently exposed to chemicals and chemical products. This study provides basic information on the outcomes of acute chemical ingestion of patients aged under 19 years. METHODS: Patients aged under 19 years who had ingested chemicals and thus visited the emergency department between January 2011 and December 2016 were included in this study. RESULTS: In all, 1,247 patients included (1,145 in the unintentional group and 102 in the intentional group). The mean age was 3.27±4.77 in the unintentional ingestion group and 16.49±1.94 in the intentional group. In the unintentional group, detergents were most frequently ingested (by 219 patients), followed by hypochlorite-based agents, ethanol, sodium hydroxide, acetone, silica gel, and citric acid. Cases of boric acid (odds ratio [OR] = 6.131), ethylene glycol (OR = 6.541), glacial acetic acid (OR = 7.644), other hydrocarbons (OR = 4.496), hypochlorite-based agent (OR = 2.627), nicotine (OR = 5.635), and sodium peroxocarbonate (OR = 6.783) ingestion was associated with a significantly high admission rate. In the intentional group, there were 54 cases of ingestion of hypochlorite-based agent, followed by detergent, ethylene glycol, ethanol, methanol and sodium peroxycarbonate. The significant risk factors for admission in the intentional group were ingestion of ethylene glycol (OR = 37.333) and hypochlorite-based agent (OR = 5.026). There was no mortality case. CONCLUSION: The most commonly ingested substances were sodium hypochlorite (hypochlorite-related agent), surfactants (detergent and soap), and ethanol. The ingestion of hypochlorite or ethylene glycol was the main risk factor for admission. Intentional ingestion was higher in adolescents than in children.

Traumatic brain injury (TBI) may cause damage to distant organs. Acute ethanol intoxication (EI) induces complex local and systemic anti-inflammatory effects and influences the early outcomes of traumatized patients. Here, we evaluated its effects on the BI-induced expression of local inflammatory mediators in the trauma-remote organs the lungs and liver. Male mice were exposed to ethanol as a single oral dose (5g·kg-1, 32%) before inducing a moderate blunt TBI. Sham groups underwent the same procedures without TBI. Ether 3 or 6h after the TBI, the lung and liver were collected. The gene expression of HMGB1, IL-6, MMP9, IL-1ß, and TNF as well as the homogenate protein levels of receptor for advanced glycation end products (RAGE), IL-6, IL-1ß, and IL-10 were analyzed. Liver samples were immunohistologically stained for HMGB1. EI decreased the gene expressions of the proinflammatory markers HMGB1, IL-6, and MMP9 in the liver upon TBI. In line with the reduced gene expression, the TBI-induced protein expression of IL-6 in liver tissue homogenates was significantly reduced by EI at 3h after TBI. While the histological HMGB1 expression was enhanced by TBI, the RAGE protein expression in the liver tissue homogenates was diminished after TBI. EI reduced the histological HMGB1 expression and enhanced the hepatic RAGE protein expression at 6h post TBI. With regard to the lungs, EI significantly reduced the gene expressions of HMGB1, IL-6, IL-1ß, and TNF upon TBI, without significantly affecting the protein expression levels of inflammatory markers (RAGE, IL-6, IL-1ß, and IL-10). At the early stage of TBI-induced inflammation, the gene expression of inflammatory mediators in both the lungs and liver is susceptible to ethanol-induced remote effects. Taken together, EI may alleviate the TBI-induced pro-inflammatory response in the trauma-distant organs, the lungs and liver, via the HMGB1-RAGE axis.

The purpose of this work is an in-depth study of main morphological features and pathogenesis of acute lung injury in cases of acute fatal poisoning with ethanol; assessment of microcirculation disorders in the respiratory system; details of the mechanisms of development of non-cardiogenic pulmonary edema. An analysis of 160 deaths of men and women aged 19 to 85 years from acute ethanol poisoning was made. Histological preparations were colored with hematoxylin and eosin according to the Van Gieson method, elastic fibers - according to Weigert. It was established that the first reaction in response to the effect of ethanol is hemodynamic disorders, then interstitial and alveolar edema develops; pronounced changes occur in endothelial cells, which lead to plasmorrhagia and hyalinosis.

OBJECTIVES: Intoxication with novel psychoactive drugs poses a significant challenge for medicine due to diagnostic difficulties, complex clinical patterns resulting from the polyethiology of poisoning, and the risk of fatal complications. MATERIAL AND METHODS: The authors of the present work have made a retrospective review of medical records of the patients hospitalized at the Toxicology Unit (TU), diagnosed with poisoning by novel recreational drugs. RESULTS: In 2008-2013, 576 patients diagnosed with that type of poisoning were admitted to the TU. Of those, 192 (33.3%) patients were positive for ethanol in addition to the most popular toxins found in the material collected from the patients, such as tetrahydrocannabinol (50 [8.6%] patients) and amphetamine (35 [6.1%] patients). The most frequent clinical symptoms observed on admission were: anxiety (433 [75.1%] patients), agitation (275 [47.7%] patients), and complaints associated with the circulatory system (225 [39.1%] patients). In the subgroup of 104 (18.0%) psychiatrist-interviewed people, a relationship was found between the suicidal ideation reported during history-taking and the following factors: earlier psychiatric treatment (p = 0.000), financial problems (p = 0.015) and prolonged unemployment (p = 0.022). CONCLUSIONS: The observed clinical pattern may be associated with sympathomimetic syndrome due to poisoning by novel psychoactive substances. Preliminary results of this research show that financial problems and a history of psychiatric treatment may enhance suicidal ideation in patients after acute poisoning by psychoactive substances.
