Background Method Results Conclusion Approximately 1% of Sweden's 90 000 annual deaths were reported caused by poisoning. In this study, we aim to describe this poisoning population's characteristics, autopsy frequency and results of toxicology testing.A national cohort study based on Swedish national registers. All deceased subjects older than 18 years with poisoning as the cause of death registered between 1 January 2000 and 31 December 2021 were included. Causes of death according to primary ICD‐10 code were analysed along with the substances found in forensic chemistry testing.There were 27 057 poisonous deaths during the study periods 2 018 495 adult deaths. Subjects deceased due to poisoning had a median age of 53 years, and 18 838 (70%) were men. A private home was the most reported location of death (52%). In total, 23 260 (87%) did undergo some sort post‐mortem examination. Drugs (synthetic narcotics, opioids, heroin) caused 12 448 (46%) deaths, and alcohols explained 9056 cases (33%). Positive toxicological tests were found in 22 550 (83%) of the subjects. The most common separate substances were ethanol, zopiclone and nordazepam.Poisoning caused 1.3% of Swedish deaths. Men in their 50s were the most common victims, and their deaths were often cause by synthetic narcotics, other opioids or alcohol. The autopsy frequency was lower than expected for poisonous deaths.

Background and Aims: Studies on adolescent alcohol use and cognition are often unable to separate the potential causal effects of alcohol use on cognition from shared etiological influences, including genetic influences or other substance use comorbidities also known to be associated with cognition, such as nicotine use. The present study aimed to fill this gap and clarify the relationship between adolescent alcohol use and young adult cognition by accounting for both measured and unmeasured confounders. Design: A random effects model accounting for nesting in families was used to control for measured confounders. Next, co‐twin comparisons were conducted within the full sample and in monozygotic twin pairs (MZ) to control for unmeasured genetic and environmental confounders shared by co‐twins. Participants/Setting: Participants were 812 individuals (58.6% female, 361 complete pairs, 146 MZ pairs) from the longitudinal FinnTwin12 study in Finland. Measurements Adolescent alcohol use was indexed with measures of frequency of use and intoxication averaged across ages 14 and 17. Cognitive outcomes were measured at average age 22 and included Trail Making Test, California Stroop test, Wechsler Adult Intelligence subtests (Vocabulary, Block Design, Digit Symbol), Digit Span subtest of Wechsler Memory Scale, Mental Rotation Test and Object Location Memory test. Covariates included sex, parental education, general cognitive ability, current alcohol use and nicotine use. Findings Greater frequency of alcohol use and frequency of intoxication across adolescence was associated with decreased vocabulary scores in the co‐twin control [freq: stnd beta = −0.12, 95% confidence interval (CI) = −0.234, −0.013] and MZ only co‐twin control models (freq: stnd beta = −0.305, 95% CI = –0.523, −0.087; intox: stnd beta = −0.301, 95% CI = ‐0.528, −0.074). Conclusions: In Finland, there appears to be little evidence that adolescent alcohol use causes cognitive deficits in young adulthood, except modest evidence for association of higher adolescent alcohol use with lower young adult vocabulary scores.

Le protoxyde d'azote (N 2 O) est un gaz utilisé en médecine pour ses propriétés anesthésiques et analgésiques et dans l'industrie comme gaz comburant ou propulseur. Ce gaz est également disponible pour un usage alimentaire à la vente en libre-service. Depuis quelques années, son utilisation est de plus en plus détournée pour un usage récréatif. Entre 2020 et 2021, le nombre de cas graves d'intoxications a augmenté de 320 % en France, démontrant une préoccupation majeure de santé publique. De plus, c'est un problème pour la sécurité routière avec une augmentation du nombre d'accidents de la route en lien avec la consommation de ce gaz. Le protoxyde d'azote provoque des effets à court terme (euphorie, désorientations, etc.) et à long terme (troubles neurologiques sensitifs et moteurs, thrombose). Ce gaz agit sur le système nerveux central, induisant des effets anxiolytique, anesthésique, antidépresseur et analgésique. Le dosage du protoxyde d'azote est difficile à cause de son élimination rapide. L'exploration biologique repose ainsi sur les anomalies secondaires liées à l'inactivation de la vitamine B12 : augmentation du taux d'acide méthylmalonique et d'homocystéine. Cependant ces deux marqueurs biologiques ne sont pas spécifiques à l'intoxication au protoxyde d'azote. Pour permettre une meilleure prise en charge des patients, il est nécessaire de trouver de nouveaux marqueurs biologiques plus spécifiques des intoxications au protoxyde d'azote. Nitrous oxide (N 2 O) is a gas used in medicine for its anesthetic and analgesic properties, and in industry as an oxidizing gas or propellant. This gas is also available on self-service for food use. In recent years, its use has been increasingly diverted to recreational purposes. Between 2020 and 2021, the number of serious cases of intoxication increased by 320% in France, demonstrating a major public health concern. It is also a problem for road safety, with an increase in the number of road accidents linked to the consumption of this gas. Nitrous oxide causes both short-term effects (euphoria, disorientation, etc.) and long-term effects (sensory and motor neurological disorders and thrombosis). This gas acts on the central nervous system, inducing anxiolytic, anesthetic, antidepressant and analgesic effects. Nitrous oxide is difficult to quantify because of its rapid elimination. Biological investigation is thus based on secondary anomalies linked to vitamin B12 inactivation: increased methylmalonic acid and homocysteine levels. However, these two biological markers are not specific to nitrous oxide intoxication. To improve patient support, we need to find new biological markers that are more specific to nitrous oxide intoxication. [ABSTRACT FROM AUTHOR]

Aims Design Setting Participants Measurements Findings Conclusions This study aimed to estimate the strength of association between prescriptions of glucose‐dependent insulinotropic polypeptide (GIP) and/or glucagon‐like peptide‐1 receptor agonists (GLP‐1 RA) and the incidence of opioid overdose and alcohol intoxication in patients with opioid use disorder (OUD) and alcohol use disorder (AUD), respectively. This study also aimed to compare the strength of the GIP/GLP‐1 RA and substance use‐outcome association among patients with comorbid type 2 diabetes and obesity.A retrospective cohort study analyzing de‐identified electronic health record data from the Oracle Cerner Real‐World Data.About 136 United States of America health systems, covering over 100 million patients, spanning January 2014 to September 2022.The study included 503 747 patients with a history of OUD and 817 309 patients with a history of AUD, aged 18 years or older.The exposure indicated the presence (one or more) or absence of GIP/GLP‐1 RA prescriptions. The outcomes were the incidence rates of opioid overdose in the OUD cohort and alcohol intoxication in the AUD cohort. Potential confounders included comorbidities and demographic factors.Patients with GIP/GLP‐1 RA prescriptions demonstrated statistically significantly lower rates of opioid overdose [adjusted incidence rate ratio (aIRR) in OUD patients: 0.60; 95% confidence interval (CI) = 0.43–0.83] and alcohol intoxication (aIRR in AUD patients: 0.50; 95% CI = 0.40–0.63) compared to those without such prescriptions. When stratified by comorbid conditions, the rate of incident opioid overdose and alcohol intoxication remained similarly protective for those prescribed GIP/GLP‐1 RA among patients with OUD and AUD.Prescriptions of glucose‐dependent insulinotropic polypeptide and/or glucagon‐like peptide‐1 receptor agonists appear to be associated with lower rates of opioid overdose and alcohol intoxication in patients with opioid use disorder and alcohol use disorder. The protective effects are consistent across various subgroups, including patients with comorbid type 2 diabetes and obesity. [ABSTRACT FROM AUTHOR]

Patients with malicious poisoning (MP) are individuals who are the victims of another person's intent to harm them through poisoning. Limited studies have investigated the clinical features and outcomes of MP. We evaluated the characteristics and outcomes of MP cases presented to emergency departments (EDs). This multicenter retrospective study enrolled MP patients who presented to three EDs in northern Taiwan. Patients with uncertain or unreasonable exposure histories and those who remained asymptomatic throughout the incident were excluded. In total, 14,329 poisoning cases were recorded between 2012 and 2019; of these, 82 (0.57%) were identified as MP cases. The incidence of MP was highest among individuals aged 13-49 years. Friends (37.8%) were the most common perpetrators, followed by family members (15.9%) and colleagues (4.9%). Sedative/hypnotics were the most frequently used substance (36.6%), followed by stimulants (26.8%) and street ketamine (6.1%). Most patients (75.6%) were discharged from the ED after a thorough assessment, while 11 (13.4%) were admitted. Of those admitted, six (7.3%) required admission to an intensive care unit. No mortalities were reported. Preschool victims (aged <6 years) exhibited more severe poisoning, with lower Glasgow Coma Scale scores and higher rates of intubation compared to non-preschool victims. Patients with MP exhibited characteristics that differed significantly from other forms of poisoning. Healthcare providers must remain vigilant for signs of MP in ED patients, particularly preschool children. [ABSTRACT FROM AUTHOR]

Phenibut is a gamma aminobutyric acid derivative with activity at γ‐aminobutyric acid (GABA)B, A and β‐phenethylamine receptors. It was developed as a drug in the former Soviet Union to overcome anxiety and improve cognitive function in military personnel. In the last decade, it has made inroads into the European and U.S. markets, being marketed for purported nootropic properties. Here, we summarize the current knowledge on phenibut, its toxicology, pharmacology, adverse health effects, and patterns of use. Publications in peer‐reviewed journals were searched in PubMed, Web of Science, and Google Scholar databases. Available literature points to adverse side effects associated with intoxication, withdrawal, and addiction to phenibut. Some of these effects can be life‐threatening, requiring hospitalization and therapeutic interventions. Supportive efforts are often complicated by a lack of knowledge regarding phenibut's toxicology and pharmacology. Ingestion of phenibut was often associated with concomitant use of other substances of abuse. As control over its online marketing seems unrealistic, current efforts need to be focused on the addition of phenibut to current drug screening tests and the development of generally accepted treatment strategies for phenibut‐associated toxicities.

Many young people in Western countries are abstaining from alcohol consumption, but their Nigerian counterparts are adopting lifestyles that valorize alcohol use and heavy drinking rituals. This study explored heavy drinking practices and alcohol-related harms among young Nigerians (students and nonstudents) who use alcohol. Although participants were highly knowledgeable about the harms associated with heavy drinking, they reported heavy drinking and normalized intoxication. Most participants consumed between 3 and 12 bottles of beer, stout and other alcoholic beverages on a single occasion and suffered multiple incidents of intoxication and loss of control with adverse outcomes. Many participants suffered more than one health-related consequence, like vomiting, hangovers, and abdominal pain, while others fell sick, which incapacitated them for many days/weeks. Heavy drinking and intoxication also adversely impacted training and studies, as some participants could not go to work or attend lectures as planned. The findings highlighted the need for prevention and intervention strategies that seek to reduce heavy drinking and associated harms by targeting the social norms around heavy drinking specifically. Lessons learned in regions with youth drinking decline may inform public health strategies that can be implemented in Nigeria. [ABSTRACT FROM AUTHOR]

Acute intoxications and poisonings are a relevant cause for ICU admission of critically ill patients. This study aimed to determine the characteristics of intoxicated patients in a tertiary center medical ICU in Austria over time and to investigate parameters associated with ICU mortality. This study was a retrospective data analysis including adult ICU patients from the years 2007 to 2021. In addition to ICU documentation, pre-hospital, and emergency department documents as well as autopsy reports were utilized. In an exploratory subanalysis, we compared these findings to a historical dataset from our facility from 1992 to 1996. We identified 581 cases admitted to the medical ICU because of acute poisoning (2007–2021), of which 45% were female and 46.6% were mixed intoxications. Suicidal intent was the primary cause of intoxication (48.2%) and ICU length of stay was median 1.2 days. The majority of deceased patients received pre-hospital mechanical CPR. Primary and secondary poison/toxin removal modalities were used in 29.9% and 11.7% of cases, whereas antidotes were administered in 54.4%. Comparing the data with a historical cohort (n = 168), we found a shift in primary detoxification away from gastric lavage and an increase in alternative secondary poison/toxin removal techniques. The ICU mortality was 4.1% and 4.2% in the present and historic cohort, respectively. Pre-existing psychiatric illnesses increased from 49% in the historic to 69% in the present cohort. Psychiatric illness predisposes patients to severe intoxications necessitating ICU care, thus increasing prevention measures seems warranted. Females did present with a different spectrum of intoxications compared to males. ICU mortality remained low over time and most deceased patients had a grim prognosis already on ICU arrival.

Excessive alcohol consumption is one of the most important factors in a substantial number of violent deaths. The aim of our study was to investigate alcohol-related deaths in the Republic of North Macedonia in the period from 2007 to 2020, in order to study the influence of elevated blood alcohol levels in violent deaths. Five hundred sixty-four post-mortem blood samples from alcohol-related death cases—natural deaths and violent deaths (suicides, accidents, and homicides)—were analyzed, and the results were evaluated according to sex, age, and cause of death. Among 564 cases, traffic accidents were the leading cause of violent death (54.3% of the cases) followed by suicides (19.9% of the cases). In the examined post-mortem samples, BAC values ranged from 0.15–6.20 g/L. The average age was 45 ± 16 years for the male and 49 ± 19 years for the female group. The biggest proportion of high BAC values was found in the group of accidents specifically road traffic accidents and accidental intoxication as well as in the group of bolus deaths. The analysis of BAC in the cases of violent deaths in the Republic of North Macedonia confirmed that consumption of alcohol is strongly related to violent deaths. The data obtained from this study could raise caution and give aid in a national strategy for the prevention of alcohol-related violent deaths. [ABSTRACT FROM AUTHOR]

This study describes a case of poisoning by pyrrolizidine alkaloids in a horse. To the best of the author's knowledge, this is the first confirmed case of Senecio ovatus poisoning. A six-year-old 450-kg Irish cob mare was presented to the Equine Clinic of the University of Veterinary Sciences Brno (Czechia) with symptoms of hepatic encephalopathy, which progressively worsened with time despite intensive therapy and led to euthanasia. A complex diagnostic and therapeutic approach including the post-mortem patoanatomical and histopathological examination is described here. Regarding the histopathology of the liver, there was necrosis with haemorrhage, fatty changes and inflammation. A later inspection of the grazing area revealed the presence of Senecio ovatus (wood ragwort). A sensitive chromatographic method was used to determine the pyrrolizidine alkaloids and their metabolites in the plasma and the liver. In both of the samples, metabolites of pyrrolizidine alkaloids were detected. Although pyrrolizidine alkaloid poisoning was proven, the histopathological findings typical for this disease were absent. It is clear from our case that the histopathology in cases of poisoning by pyrrolizidine alkaloids may not always be conclusive. [ABSTRACT FROM AUTHOR]

Introduction: The increase in the production of substances to enhance the quality of life, the biodiversity of the different ecosystems in Mexico, and the unique characteristics of pediatric patients, contribute to intoxications within this population. Method: Analytical retrospective study of admissions to pediatric emergency care due to poisoning in < 16-year-old (2016 to 2020). Included variables were age, gender, type of toxic substance, exposure characteristics, and the season of the year. Frequencies, percentages, range, average and standard deviation were obteined. In the bivariate análisis, the Chi square test was used. A p-value < 0.05 was considered statistically significant. Results: Over 5 years, there were 459 cases, with a prevalence of 3.16%. No gender predominance was observed. The most common was caused by venomous animals (28.5%), followed by medication ingestion (27.6%). Only 5% of cases were suicide attempts, the rest were accidental (95%). Children up to 5 years old were more commonly by medication ingestion, hydrocarbons, or household products (p = 0.03, p = 0.0001), while the causes in older children were contact with venomous animals and ingestion of stimulants drugs (alcohol, amphetamines, cannabis, cocaine) (p = 0.0001, p = 0.006). Intoxication with quaternary ammonium herbicides was lethal in all cases. Conclusions: Children under the age of 5 are more susceptible to intoxication from common household products. Older kids tend to be more frequently a combination of stimulants drugs. [ABSTRACT FROM AUTHOR]

Background: Consumption of stimulant drugs, a heterogeneous group of addictive substances, has significantly increased in recent years with rising numbers of stimulant-associated intoxication and deaths. Objective: To provide an overview of recent scientific evidence of the diagnosis and treatment of stimulant use disorders. Material and methods: A literature review of the neuropathology, clinical presentation, diagnostic criteria and evidence-based treatment for stimulant use disorders. Results: The chronic use of stimulant drugs is associated with significant physical (e.g., hypertension, tachycardia and dyspnoea) and psychological harm (e.g., dependence, psychotic disorders and affective disorders). Despite major advances in the research of the neuropathology of stimulant use disorder and the refinement of diagnostic criteria, the disorder still presents a challenge, not least because of the lack of effective treatments. There are currently no approved pharmacotherapeutic interventions for stimulant use disorder and meta-analyses show that the efficacy of behavioural interventions is low to moderate, similar to cognitive behavioural treatment. Conclusion: Despite growing insights into the neuropathology associated with stimulant use disorder, treatment remains a challenge. The lack of effective interventions makes it difficult to give clear recommendations for the clinical practice. Further scientific research is thus warranted. [ABSTRACT FROM AUTHOR]

Background Overdoses of carbamazepine may occur due to various reasons. The summary of product characteristics of carbamazepine includes information about the possibility of side effects after taking this drug. However, the symptoms described do not include coronary vasospasm, which occurred in the case described. Making such a diagnosis is a key element in therapeutic management, as it changes further clinical decisions. Case summary A 46-year-old patient was admitted to the hospital for disorders of consciousness following an overdose of carbamazepine. On the second day, the patient exhibited respiratory distress. Subsequently, the patient was transferred to the intensive care unit, intubated, and placed on mechanical ventilation. On the same day, the patient experienced recurrent cardiac arrhythmias in the form of pulseless ventricular tachycardia and ventricular fibrillation; the patient was resuscitated and defibrillated eight times. Due to a rapid decline in cardiac output coupled with persistent electrocardiographic changes and haemodynamic instability, the patient underwent urgent coronary angiography. The procedure revealed a spasm in the initial segment of the circumflex branch of the left coronary artery, which subsequently resolved following nitroglycerin administration. Subsequent to the implementation of this therapeutic approach, a reduction in the demand for norepinephrine and dobutamine was achieved. In the following days, the patient's general condition improved. The patient was discharged home while maintaining full cognitive capacity and cardiovascular and respiratory fitness. Discussion In the case described, the expeditious performance of a cardiological diagnostic evaluation played a pivotal role in achieving therapeutic success, enabling the prompt initiation of appropriate treatment.

Illicit drug use is common among attendees of electronic dance music (EDM) festivals, but is often significantly underreported by participants. The current study aimed to compare the prevalence and over- and under-reporting of illicit drug use among attendees at EDM festivals in two European countries with distinct drug laws and cultures. Self-reported data regarding recent drug use were collected through interviews. Participants' blood alcohol concentrations were measured using a breathalyzer. Recent illicit drug use was assessed through sampling microparticles in the breath and consequent off-site analysis through liquid chromatography and tandem mass spectroscopy. Illicit drug use was higher in Belgium than in Sweden as indicated by self-reports (56.8 vs. 4.3%) and drug testing (37.2 vs. 12.5%). Underreporting was higher in Sweden than in Belgium; in Sweden, only 2.6% reported taking an illicit drug other than cannabis, whereas 11.6% tested positive, while the corresponding figures in Belgium were 36.5% and 36.9%. In both countries, results from self-reporting and drug testing for specific drugs matched poorly at the individual level, indicating unwitting consumption of substances. This study indicates that the drug use prevalence and the likelihood of disclosure may differ between countries or cultures, which should be considered when choosing methods to investigate drug use prevalence.

This umbrella review presents different therapeutic approaches for Paraquat (PQ) poisoning to reach a general conclusion on what is the best treatment to reduce mortality. A comprehensive electronic search of relevant databases was conducted from inception to April 2022. Only systematic reviews with or without meta‐analysis were eligible for this review. Initially, 123 titles were retrieved, and after removing the duplicates, 89 titles and abstracts were reviewed. Finally, 34 full texts were screened, and of these, 11 qualitative systematic reviews and quantitative meta-analyses (including 12 trials) were eligible. The mortality rate following all included interventions was 24% less likely to occur than in routine management (RR: 0.763, 95% CI 0.649–0.897; p = 0.001). In subgroup analysis, the efficacy of immunosuppressive therapy and Ambroxol was higher than other interventions. The mortality rate following Ambroxol was 31% less likely to occur than routine management (RR: 0.690, 95% CI 0.552–0.863; p = 0.001). This rate was similar to the immunosuppressive therapy (RR: 0.700, 95% CI: 0.627–0.782; p < 0.001). Other interventions did not affect the reduction of the mortality rate (p > 0.05). To conclude the accurate result, further studies are recommended to evaluate the efficacy and safety of immunosuppressive therapy. [ABSTRACT FROM AUTHOR]

Background/Objectives: Poisonings among children are a major cause of morbidity and mortality worldwide and present a significant challenge for emergency medical services (EMS). The aim of this study was to analyze the types of substances causing poisonings and the intention of poisonings in children, providing detailed information on the most common causes of poisonings in different age groups. Methods: A retrospective study was conducted analyzing medical records of pediatric patients under the care of emergency medical services (EMS) in Wroclaw, Poland, between 2015 and 2017. The study included all patients under 18 years old diagnosed with poisoning. Data collected included age, sex, cause of poisoning, location of the incident, neurological status (GCS), and the type of healthcare facility. Results: The study included 484 patients, with a mean age of 13 years. The largest age group was 16–18 years (44%), and the majority were female (58%). The most common causes of poisonings were alcohol (29.3%), medications (26%), and intoxicants (24.8%). Over half of the incidents occurred at home (52.5%). Intentional poisonings constituted 75% of cases, particularly involving alcohol (38.6%), intoxicants (32%), and medications (26.7%). Accidental poisonings were mainly due to household chemicals (28.7%) and carbon monoxide (27%). The differences in causes and locations of poisonings were statistically significant (p < 0.001). Conclusions: Our study showed that the most common causes of poisonings among children were alcohol, medications, and intoxicants. Poisonings most frequently occurred at home, especially with medications, while outside the home, alcohol and intoxicants were predominant. This study was not registered. [ABSTRACT FROM AUTHOR]

Influenza and acute respiratory viral infections (ARVI) impose a substantial damage to the population health in the Russian Federation due to their seasonal circulation and predominantly affect young children. A very few data on the cytokine profile, the nonspecific LPO — AOD system and their relationships with clinical characteristics in such diseases in preschool children are available. The aim of this study was to assess the cytokine profile, LPO — AOD system parameters and their relationship with the clinical and laboratory characteristics of diseases in preschool children with influenza and other ARVI. 86 preschool children (3–6 years old) were examined: with an established diagnosis of influenza (n = 31), non-influenza ARVI (n = 28), apparently healthy children (control group (n = 27). All pediatric samples were analyzed by enzyme-linked immunosorbent assay assessing blood serum concentrations of C-reactive protein and cytokines IL-1β, IL-4, IL-6, IL-8, TNFα, IFNα, IFNγ. Spectrophotometric, fluorometric and enzyme immunoassay methods to assess the state of the “LPO — AOD” system were used. In the group of children with influenza vs other ARVI, a higher incidence of intoxication syndrome was revealed. Cytokine profile in children from both clinical groups compared with control cohort was featured with higher indicators of both pro-inflammatory and anti-inflammatory origin. Children with non-influenza ARVI, had increased magnitude of LPO final products in the nonspecific LPO — AOD system along with lowered concentration of fat-soluble vitamins, general antioxidant activity, GSH level, and SOD activity. In the group with influenza, the level of primary and final lipid peroxidation products was increased, whereas that of for retinol,α-tocopherol, and total antioxidant activity was decreased paralleled with higher GSSG and SOD levels. Numerous correlations were noted in the group of children with ARVI: IL-1β/ketones, IL-6/ketones, IL-8/ketones, TNFα/ketones, IL-4/ketones, IFNg/shortness of breath, IFNα/cough, double bonds/fever, double bonds/AST, SO/intoxication, retinol/fever, GSSG/cough. The influenza group differed in the following relationships: IL-4/ketones, IL-4/fever, IFNα/ketones, CDs/AST. It can be concluded that in preschool children with ARVI and influenza, changes in the cytokine profile are accompanied by increased pro- and anti-inflammatory cytokine levels, increased intensity of lipid peroxidation reactions along with reduced magnitude of antioxidant factors. In the group with ARVI, there was a relationship between the final toxic products of lipid peroxidation — Schiff bases — and the intoxication index, as well as the presence of protective mechanisms in the form of connections between interferons and disease clinical manifestations. The group with influenza was distinguished by the presence of protective relations, which may have a beneficial effect in the context of developing pathological process. The data obtained will help expand the understanding of the pathogenetic mechanisms related to immune reactivity and nonspecific lipid peroxidation reactions in preschool patients and formulate appropriate measures for correction.

Background: There are only rare case reports that revealed the efavirenz (EFV) toxicity. Case Report: This study presents an acute intoxication with 12 g of efavirenz in a 16-year-old healthy girl whose main problem was dose-dependent neurotoxicity. No other serious EFV-related side effects were seen. Previous serious side effects of EFV were observed in HIV-infected patients who underwent long-term combination drug therapy. Conclusion: Accordingly, in terms of the key clinical messages, serious adverse effects of efavirenz are expected to be observed in long-term use in combination with other antiretroviral drugs.

The article presents an analysis of fire hazard of high-rise buildings and skyscrapers. The author notes a range of factors significantly impacting on the course of emergency rescue operations, including the difficulty of evacuating people from the burning buildings (e.g., due to the rapid movement of combustion products to the roof of the building, the duration of the descent down the stairs to evacuation exits, etc.), uncertainty of toxicity (the nature of gases formed during combustion, the synergism of their toxic effect, the determination of toxic dose), difficulties in rescuing people from the upper floors of the building and in the process of extinguishing a fire (due to the lack of necessary fire equipment), as well as the behavior of people caught in a fire in the building. The inadmissibility of using «risk-analysis» in the forensic practice is emphasized, since the correct initial data (linear and mass burning rates) for its calculation is unknown. The article is intended for fire experts of the forensic institutions of various departments, investigators of the Ministry of Emergency Situations and employees of engineering organizations.

Abstract Introduction Ricin intoxication is a serious condition with symptoms ranging from mild gastroenteritis to fatal outcomes due to shock and multi-organ failure. Intoxication from the ingestion of castor seeds is uncommon. However, its diagnosis is crucial, particularly with a clear history of exposure to castor seeds, regardless of the route of exposure (enteral or parenteral). Prompt diagnosis is essential to monitor and manage the patient effectively and to prevent potentially fatal outcomes. We report a case where ingestion of castor seeds resulted in gastroenteritis severe enough to necessitate emergency medical care. Case report We present the case of a 47-year-old Belgian woman of Moroccan descent, previously healthy who was admitted to the emergency department with symptoms of colicky abdominal pain, diarrhea, and vomiting following the ingestion of six castor beans. The patient was diagnosed with ricin intoxication, admitted for observation, and received symptomatic treatment. She was discharged home after a complete recovery three days later. Conclusion Our report underscores the clinical manifestations, hemodynamic changes, laboratory findings, and treatment of intoxication due to castor seed ingestion. It contributes to the limited literature on castor seed poisoning in humans, with a specific focus on cases in Belgium. This report aims to raise awareness among clinicians about this condition and emphasizes the importance of a comprehensive history-taking to prevent misdiagnosis and malpractice.

Abstract Cannabigerol (CBG) is a phytocannabinoid increasing in popularity, with preclinical research indicating it has anxiolytic and antidepressant effects. However, there are no published clinical trials to corroborate these findings in humans. The primary objective of this study was to examine acute effects of CBG on anxiety, stress, and mood. Secondary objectives were to examine whether CBG produces subjective drug effects or motor and cognitive impairments. A double-blind, placebo-controlled cross-over field trial was conducted with 34 healthy adult participants. Participants completed two sessions (with a one-week washout period) via Zoom. In each, they provided ratings of anxiety, stress, mood, and subjective drug effects prior to double-blind administration of 20 mg hemp-derived CBG or placebo tincture (T0). These ratings were collected again after participants ingested the product and completed an online survey (T1), the Trier Social Stress Test (T2), a verbal memory test and the DRUID impairment app (T3). Relative to placebo, there was a significant main effect of CBG on overall reductions in anxiety as well as reductions in stress at T1. CBG also enhanced verbal memory relative to placebo. There was no evidence of subjective drug effects or impairment. CBG may represent a novel option to reduce stress and anxiety in healthy adults.

Introduction: Salbutamol is a moderately selective beta-2-adrenergic agonist. Various side effects can occur because of beta-1 and beta-2 receptor activation. Due to the large volume of distribution, it is not considered dialyzable. Case Presentation: A patient with salbutamol intoxication, which developed as a result of a medical error in a patient with sepsis, Down syndrome, and liver cirrhosis, is presented. Initial treatment was partially successful and antibiotic adjustments were made. After his respiratory failure worsened, the patient needed non-invasive ventilation, and previously undiagnosed chronic obstructive pulmonary disease was suspected. He was prescribed intravenous methylprednisolone but accidently received 5 mg of salbutamol (albuterol), which led to immediate severe arrhythmic tachycardia with hemodynamic collapse. After unsuccessful cardioversion and treatment with landiolol infusion, salvage hemodialysis was commenced to decrease suspectedly highly elevated serum salbutamol levels. After 30 min, sinus rhythm with normocardia was observed. After the hemodialysis termination, no rebound tachycardia was noted, but due to severe septic shock, the hypotension was ongoing and vasoactive medications were adjusted. However, the measured levels of plasma salbutamol and data from literature do not support the view that hemodialysis was the cause of the described improvement: the total amount of the drug cleared was very small (2.8% of total dose). Conclusion: Our results confirm a large volume of salbutamol distribution; the measured levels are within observed therapeutic levels; and the measured half-life time during hemodialysis (3.1 h) is comparable to observed half-life times in therapeutic settings. The observed favorable clinical benefit associated with dialysis may be fortuitous, highlighting potential bias toward positive clinical outcomes and unproven (“salvage”) therapies.

Abstract Background Over the last decade, there has been an emerging trend of recreational misuse of several drugs and inhaled solvent including ethyl chloride. This case report follows CARE guidelines and highlights, with supporting video, the neurological features of ethyl chloride intoxication. Case presentation A 48-year-old man was seen for the sudden occurrence of an unsteady gait with dizziness. His only medical history was a chronic and treated HIV infection without any complications. Clinical examination revealed a cerebellar syndrome associated with impairment of short-term memory. Biological and radiological workups were normal. After several days, the patient recalled ethyl chloride inhalation. He fully recovered after being discharged from hospital. Conclusion Clinicians should recognise the clinical features and neurological manifestations of ethyl chloride intoxication due to the potential fatal cardiovascular complications of this intoxication.

Introduction: Ricin intoxication is a serious condition with symptoms ranging from mild gastroenteritis to fatal outcomes due to shock and multi-organ failure. Intoxication from the ingestion of castor seeds is uncommon. However, its diagnosis is crucial, particularly with a clear history of exposure to castor seeds, regardless of the route of exposure (enteral or parenteral). Prompt diagnosis is essential to monitor and manage the patient effectively and to prevent potentially fatal outcomes. We report a case where ingestion of castor seeds resulted in gastroenteritis severe enough to necessitate emergency medical care. Case report: We present the case of a 47-year-old Belgian woman of Moroccan descent, previously healthy who was admitted to the emergency department with symptoms of colicky abdominal pain, diarrhea, and vomiting following the ingestion of six castor beans. The patient was diagnosed with ricin intoxication, admitted for observation, and received symptomatic treatment. She was discharged home after a complete recovery three days later. Conclusion: Our report underscores the clinical manifestations, hemodynamic changes, laboratory findings, and treatment of intoxication due to castor seed ingestion. It contributes to the limited literature on castor seed poisoning in humans, with a specific focus on cases in Belgium. This report aims to raise awareness among clinicians about this condition and emphasizes the importance of a comprehensive history-taking to prevent misdiagnosis and malpractice.

The aim of our study is to define the most frequent etiology, clinical presentation, and predictive factors of outcome in children with acute ataxia (AA) and to determine "the red flags" in the diagnostic approach to children with AA. The retrospective study included the patients with AA treated in the institute from 2015 to 2021. The inclusion criteria were children aged 1–18 years, evolution time of ataxia within 72 h, and diagnosis made by a physician. The exclusion criteria were anamnestic data about ataxia without confirmation by any physician, chronic/persistent ataxia, and psychogenic or postictal ataxia. Clinical presentation was divided into two categories: (1) isolated cerebellar signs (CS): ataxic gait, dysmetria, dysdiadochokinesia, intention tremor, dysarthria, and nystagmus; (2) CS-plus symptoms which included CS associated with any of other symptoms such as encephalopathy (GCS < 15), awareness disturbances, vomiting, headache, a new onset limb or facial paresis, torticollis, hypotonia, and opsoclonus. The outcome was assessed at the end of hospitalization and was defined as complete or incomplete recovery. The study included 76 children, with a mean age of 5.7 years (IQR 2.1–8.3). The most frequent causes of AA were immune-mediated/infective cerebellar ataxia in 27 (35.5%), and intoxication in 24 (31.6%) cases, followed by vestibular ataxia, opsoclonus-myoclonus-ataxia syndrome, and intracranial expansive process. Forty-two (56%) cases experienced isolated CS, and 35 (46%) cases had CS-plus. Complete recovery was experienced by 62 (81.6%) patients. Analysis of some risk factors (sex, age, presence of previous infection, "cerebellar plus symptoms," and structural abnormalities/neuroimaging abnormalities) and their relation to outcome was performed. Analysis showed that presence of additional symptoms to ataxia, so called "cerebellar plus symptoms" (p = 0.002) and structural abnormalities (p < 0.001), had statistically higher frequency of poor outcome. Statistical significance remained in the univariate analysis. Significant data was included in multivariate logistic regression analysis which also showed that presence of "cerebellar plus symptoms" (p = 0.021) and structural abnormalities (p = 0.002) is related to a poor outcome. Most of the children with AA have "benign" etiology such as intoxication and post/parainfectious cerebellar ataxia with favorable outcomes. On the other hand, AA might be the first manifestation of CNS neoplasm or paraneoplastic phenomena. "The red flags" associated with cerebellar signs are limbs or facial palsy, hypotonia, GCS < 15, vomiting, opsoclonus, headache, myoclonus, visual impairment, torticollis, and vertigo. The presence of those signs and/or structural brain abnormalities was related to poor outcomes in children with AA. [ABSTRACT FROM AUTHOR]

Fentanyl is an opioid with powerful analgesic effects and a high speed of action. Due to its pharmacological properties, this molecule has therapeutic application as an anesthetic in surgery or as palliative therapy for cancer patients. Unfortunately, in recent years, the easy availability of this substance, the low cost and the illegal online market have favored the large-scale diffusion of fentanyl. Fentanyl is available in different forms, including nasal spray, oral patches, soluble capsules, aerosol or the new version of fentanyl mixed with other drugs, making its use very widespread. Subjects of various ages are involved in fentanyl consumption, including minors that have not yet reached adolescence. In this work, we performed a literature review using the search engines PubMed NCBI and SCOPUS regarding episodes of acute fentanyl intoxication occurring in those of a pediatric age using the Mesh Terms "fentanyl" AND "overdose" AND "children". The inclusion criteria were English papers published in the last 10 years regarding the cases of children under the age of 10. We evaluated the most frequent methods of intake and the circumstances of such episodes. In cases of death, we analyzed the autopsy, the toxicological findings and the investigations carried out. The review results show that in this age group (under < 10 y.o. s), it is possible to identify the risk factors for fentanyl intake, such as the presence of this molecule within the family unit due to drug addiction or medical therapy. The results also demonstrate a significant risk of underestimation of this phenomenon, since the molecule is often not investigated through adequate toxicological analysis. These results, therefore, suggest always carrying out toxicological investigations in the case of suspected fentanyl intoxication, both on patients or cadavers. The investigations must always include a urinary screening for opiates, and the request for a second level analysis with molecule dosage in cases of positivity or in cases of strong suspicion for assumption. In cases of intoxication in a family context of drug addiction, it is necessary to investigate the chronicity of the intake through hair analysis and evaluate the possible co-administration of other drugs. In conclusion, we suggest a protocol, applicable both on patients or cadavers, which can be useful for physicians and forensic pathologists in order to promptly identify these cases and allow for the reporting of them to the judicial authorities with the adoption of strict prevention and control measures.

Cannabigerol (CBG) is a phytocannabinoid increasing in popularity, with preclinical research indicating it has anxiolytic and antidepressant effects. However, there are no published clinical trials to corroborate these findings in humans. The primary objective of this study was to examine acute effects of CBG on anxiety, stress, and mood. Secondary objectives were to examine whether CBG produces subjective drug effects or motor and cognitive impairments. A double-blind, placebo-controlled cross-over field trial was conducted with 34 healthy adult participants. Participants completed two sessions (with a one-week washout period) via Zoom. In each, they provided ratings of anxiety, stress, mood, and subjective drug effects prior to double-blind administration of 20 mg hemp-derived CBG or placebo tincture (T0).

Introduction. Il existe une relation complexe entre le statut résidentiel et la consommation de substances. En effet, la consommation de substances réduit les perspectives de logement et le fait d'être sans logement augmente les raisons de consommer des substances ainsi que les risques et la stigmatisation qui y sont associés. Méthodologie. Dans cette analyse descriptive des personnes sans logement qui ont perdu la vie en raison d'une intoxication aiguë accidentelle liée à une substance au Canada, nous avons utilisé les données relatives aux enquêtes sur les décès tirées d'une étude nationale d'examen des dossiers concernant les décès par intoxication aiguë due à une substance en 2016 et 2017, afin de comparer les facteurs sociodémographiques, les antécédents médicaux, les circonstances du décès et les substances ayant contribué au décès des personnes sans logement et des personnes non identifiées comme sans logement, au moyen du test du khi carré de Pearson. Nous avons comparé le profil démographique des personnes décédées d'une intoxication aiguë aux données du Dénombrement ponctuel coordonné de l'itinérance dans les collectivités canadiennes de 2016 et du Recensement de 2016. Résultats. Les personnes sans logement étaient nettement surreprésentées parmi les personnes décédées d'une intoxication aiguë en 2016 et 2017 (8,9 % contre moins de 1 % de la population générale). L'intoxication aiguë ayant entraîné le décès des personnes sans logement a eu lieu plus souvent à l'extérieur (24 %); un opioïde ou un stimulant a plus fréquemment contribué à leur décès (68 % à 82 %; les deux substances ont été responsables de 59 % des décès) et ces personnes avaient plus souvent été libérées d'un établissement correctionnel ou été autorisées à sortir d'un établissement de soins de santé au cours du mois précédant leur décès (7 %). Conclusion. Nous présentons plusieurs possibilités de réduire les décès attribuables à une intoxication aiguë chez les personnes sans logement, notamment lors de la prise de contact avec les services de santé et d'autres établissements, par des mesures de soutien à la réduction des méfaits liés à la consommation d'opioïdes et de stimulants ainsi que par la création d'environnements plus sûrs pour les personnes sans logement.

Cadmium (Cd) toxicity poses a significant threat to human health and the environment due to its widespread occurrence and persistence. In recent years, considerable attention has been directed towards exploring natural compounds with potential protective effects against Cd-induced toxicity. Among these compounds, resveratrol (RV) has emerged as a promising candidate, demonstrating a range of beneficial effects attributed to its antioxidant and anti-inflammatory properties. This literature review systematically evaluates the protective role of RV against Cd toxicity, considering the various mechanisms of action involved. A comprehensive analysis of both in vitro and in vivo studies is conducted to provide a comprehensive understanding of RV efficacy in mitigating Cd-induced damage. Additionally, this review highlights the importance of phytoremediation strategies in addressing Cd contamination, emphasizing the potential of RV in enhancing the efficiency of such remediation techniques. Through the integration of diverse research findings, this review underscores the therapeutic potential of RV in combating Cd toxicity and underscores the need for further investigation to elucidate its precise mechanisms of action and optimize its application in environmental and clinical settings.

Occupational toxicology in the paper industry aims to study the occupational risks of exposure to chemical, physical and biological compounds used in the workplace, in addition to helping and preventing the possible appearance of adverse effects on the health of workers due to exposure to themselves. The pulp and paper industries use several chemical agents in the production of packaging, demanding attention to handling due to their toxic action, currently research in this area is scarce. In turn, this article sought to demonstrate, through questionnaires and chemical analysis, contamination by hydrochloric acid and sodium hydroxide in workers during their work activity in a paper industry located in southern Brazil. Seeking to increase the studies, the workers' knowledge about the agents was investigated, as well as the use of Personal Protective Equipment (PPE) and the contamination of these individuals with the aforementioned agents. To achieve these objectives, interviews were applied to employees from four different shifts and the clothes were analyzed after the end of the shift through titration and pHmetry analysis. The results of the analyzes showed a lack of awareness among the workers, evidence of contamination and traces of sodium hydroxide on the employees' clothing. These results imply reflection on the indispensability of personal protective equipment. Highlighting the need for the routine use of PPE, as well as offering the necessary qualification for workers, in order to prevent and minimize occupational accidents. [ABSTRACT FROM AUTHOR]

Tetrahydrozoline is an alpha agonist imidazole derivative found in over-the-counter decongestive eye and nasal drops. The drug was patented in 1954 and was available for medical use in 1959. This drug recently gained the attention of law enforcement as it has been utilized in criminal activity such as homicide and drug-facilitated sexual assault. The aim of this scoping review is to scope the literature for all mentions of tetrahydrozoline eye/nasal drops use in a non-medical context to delineate areas of future research and development. We used Google Scholar and PUBMED/Medline databases to search for non-medicinal and criminal uses of THZ. The search word used was "tetrahydrozoline." A total of 15 articles matched our criteria. Among the case reports, two (11.1%) cases reported on drug-facilitated sexual assault, and two (11.1%) cases used THZ eyedrops to attempt suicide. Incidental ingestion of THZ eyedrops was reported in eight (44.4%) cases, three (16.7%) cases of attempted murder were reported, two (11.1%) cases of intentional ingestion were reported, and one (5.5%) case was a combination of drug-facilitated sexual assault and attempted murder. The most common clinical presentation was unexplained and resistant bradycardia and hypotension. THZ eye drops can be used to produce false negative results on drug tests. This study recognizes that THZ can be used in non-medicinal and criminal uses. There is room for future research and development. More studies should be conducted to better understand the mechanism of action, therapeutic window, and toxicity levels among various age groups at different methods of intake and to find an effective treatment in case of overdose. Eyedrop and nasal decongestant bottles should be designed with child proofing to prevent incidental ingestion and should contain warning labels. A fast and alternative test to GC/MS can be developed to ease the diagnosis of THZ toxicity. Purchases of this medication may need to be monitored. [ABSTRACT FROM AUTHOR]

Access to literature on clozapine in Russian language remains strikingly limited. We aimed to identify and translate clinical evidence on clozapine-based treatment outcomes. We performed a systematic review in PubMed, Embase and scientific indexes from former USSR states searching for articles published in Russian from the database inception till January 2023 and summarized the data in a scoping review (PROSPERO Reg. Number CRD42023386737). A total of 60 papers were included comprising eight main topic categories: 1) clozapine-related intoxications (n = 20), 2) effectiveness/efficacy and safety of clozapine treatment (n = 14), 3) adverse drug-induced reactions (ADRs) related to clozapine treatment (n = 9), 4) therapeutic drug monitoring for clozapine (n = 5), 5) combination of clozapine and non-pharmacological treatments (n = 4), 6) pharmacoepidemiology of clozapine (n = 3), 7) effects of clozapine on the brain electrical activity (n = 3), and 8) novel clozapine formulations (n = 2). Among clozapine-related intoxications there were reports of criminal poisoning, which was associated with low lethality. Worse outcomes were accompanied by systemic reactions to intoxications. Clinical benefits of hemoadsorption were reported in the management of clozapine-related intoxications. Only half of studies reporting clozapine effectiveness used standardized scales to assess outcomes. Clozapine superiority in treatment-resistant schizophrenia (TRS) was replicated in one trial. No reports of clozapine-related agranulocytosis were identified. Clozapine ranked among most prescribed antipsychotics for TRS and non-TRS. As clinical research in former USSR states is advancing to adopt western clinical research standards, comparability and extrapolation of findings is expected to increase, with transfer of older findings to clinical practice being particularly challenging.

Honeybee venom is one of the natural substances produced by bees (Apis mellifera). Their venom gland produces venom which plays a defensive role. In this study a concentration of macro and trace elements (Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Sb, Se, Sr, Pb and Zn) in foragers′ and honeybees′ venom was analysed by axial inductively coupled plasma optical emission spectrometry (ICP OES) with good validation parameters to differentiate the element accumulation ability in honeybee venom. Cumulative ability for some elements (As, Al, Ba, Cr, Li, Mo, Pb, and Zn) in bee venom was clearly demonstrated. Oppositely, levels of macro elements (Ca, K, Mg and Na) in venom were several times lower compared to the levels detected in foragers. Moreover, PCA analysis of bee samples showed that Cr was associated with locality Košice, and Cd with locality Krompachy; both have rich industrial history. Since some of analysed elements are potentially toxic for humans, a risk assessment for bee-stung scenario was also calculated. A new way of exposure to potentially toxic elements via honeybee stung was showed in this study. Non-carcinogenic risk assessment for humans to selected toxic elements (As, Cd, Cr, Ni, and Pb) demonstrated acceptable risk and moreover the same we may conclude for potential carcinogenic risk for beekeepers exposed to As, Cd, Ni, and Pb via venom over their whole life.

Objective: To identify mechanisms and types of injuries in patients having sustained craniofacial fractures under the influence of alcohol, and to compare the frequencies of them between males and females. Materials and methods: Patients included were adults who had been diagnosed with craniofacial fractures at Töölö Hospital Emergency Department, Helsinki University Hospital, Finland, and who had been under the influence of alcohol at the time of injury. The primary outcome variables were assault-related and fall-related injury mechanisms. The secondary outcome variables were other injury mechanisms, time of accident, type of craniofacial fracture and severity of facial fracture. The primary predictor variable was sex. The control variable was age at the time of injury. The statistical modelling was executed using logistic regression. Results: Of the total of 2,859 patients with craniofacial fractures, 1,014 patients (35.5%) fulfilled the inclusion criteria. Males predominated (84.6%). Assault (38.0%) was the most frequent aetiology. Compared to the odds of females, males had 2.8 times greater odds for assault, 2.4 times greater odds for isolated cranial fracture and 1.7 times greater odds for a facial injury severity score of ≥ 3. Females had 2.0 times greater odds for any fall compared to the odds of males. Conclusions: Particularly male patients are frequently under the influence of alcohol at the time of injury, predisposing them to assault and severe facial fractures more often than females. Codes of practice on how to identify unhealthy alcohol use and how to intervene are recommended.
