INTRODUCTION: Cannabis is the most common recreational drug worldwide and synthetic cannabinoid receptor agonists are currently the largest group of new psychoactive substances. The aim of this study was to compare the clinical features and outcomes of lone acute cannabis toxicity with lone acute synthetic cannabinoid receptor agonist toxicity in a large series of presentations to European emergency departments between 2013-2020. METHODS: Self-reported drug exposure, clinical, and outcome data were extracted from the European Drug Emergencies Network Plus which is a surveillance network that records data on drug-related emergency department presentations to 36 centres in 24 European countries. Cannabis exposure was considered the control in all analyses. To compare the lone cannabis and lone synthetic cannabinoid receptor agonist groups, univariate analysis using chi squared testing was used for categorical variables and non-parametric Mann-Whitney U- testing for continuous variables. Statistical significance was defined as a P value of <0.05. RESULTS: Between 2013-2020 there were 54,314 drug related presentations of which 2,657 were lone cannabis exposures and 503 lone synthetic cannabinoid receptor agonist exposures. Synthetic cannabinoid receptor agonist presentations had statistically significantly higher rates of drowsiness, coma, agitation, seizures and bradycardia at the time of presentation. Cannabis presentations were significantly more likely to have palpitations, chest pain, hypertension, tachycardia, anxiety, vomiting and headache. DISCUSSION: Emergency department presentations involving lone synthetic cannabinoid receptor agonist exposures were more likely to have neuropsychiatric features and be admitted to a psychiatric ward, and lone cannabis exposures were more likely to have cardiovascular features. Previous studies have shown variability in the acute toxicity of synthetic cannabinoid receptor agonists compared with cannabis but there is little comparative data available on lone exposures. There is limited direct comparison in the current literature between lone synthetic cannabinoid receptor agonist and lone cannabis exposure, with only two previous poison centre series and two clinical series. Whilst this study is limited by self-report being used to identify the drug(s) involved in the presentations, previous studies have demonstrated that self-report is reliable in emergency department presentations with acute drug toxicity. CONCLUSION: This study directly compares presentations with acute drug toxicity related to the lone use of cannabis or synthetic cannabinoid receptor agonists. It supports previous findings of increased neuropsychiatric toxicity from synthetic cannabinoid receptor agonists compared to cannabis and provides further data on cardiovascular toxicity in lone cannabis use.

INTRODUCTION: Snakebite incidence varies across Europe. However, there is limited research from Central and Southeastern Europe. These regions are notable for the presence of the common European adder (Vipera berus) and the more venomous nose-horned viper (Vipera ammodytes). No standard European antivenom protocol exists. The aim was to assess the epidemiology and treatment of viper bites in this region, focusing on a comparison of bites from Vipera berus and Vipera ammodytes. METHODS: We conducted a prospective multicenter study in Central and Southeastern Europe from 2018 to 2020. This study included poison centres and toxicology-associated hospital wards in Poland, the Czech Republic, Slovakia, Hungary, Slovenia, Croatia, Serbia, and Bulgaria. The following data were collected: age, gender, Vipera species, snakebite site, clinical picture, laboratory results, Audebert's clinical severity grading score, and antivenom therapy. RESULTS: The annual incidence of viper bites in Central and Southeast Europe was estimated at 2.55 bites per million population. Within their respective geographical distribution areas, the incidence of Vipera ammodytes bites (1.61 bites per million population) was higher than Vipera berus bites (1.00 bites per million population). Patients bitten by Vipera ammodytes more frequently reported local pain and developed thrombocytopenia. Antivenom treatment was more commonly administered in Vipera ammodytes bites (72%) compared to Vipera berus bites (39%). The incidence of Vipera ammodytes bites treated with antivenom within its geographical distribution area was three times higher than Vipera berus bites treated with antivenom (1.16 bites per million population versus 0.39 bites per million population). No deaths were reported. CONCLUSIONS: The estimated incidence of viper bites in Central and Southeastern Europe is at least 2.55 per million population. Vipera ammodytes bites are more common and severe, characterized by higher frequencies of pain and thrombocytopenia. Antivenom is needed more often for Vipera ammodytes bites. It is vital that enough European Medicines Agency-approved Vipera ammodytes antivenom is produced and offered affordably.

OBJECTIVE: To analyse the relative percentage of acute recreational drug toxicity emergency department (ED) presentations involving the main drug groups according to age and sex and investigate different patterns based on sex and age strata. METHODS: We analysed all patients with acute recreational drug toxicity included by the Euro-DEN Plus dataset (22 EDs in 14 European countries) between October 2013 and December 2016 (39 months). Drugs were grouped as: opioids, cocaine, cannabis, amphetamines, gamma-hydroxybutyrate (GHB), hallucinogens, new psychoactive substances (NPS), benzodiazepines and ketamine. Descriptive data by age and sex are presented and compared among age/sex categories and among drug families. RESULTS: Of 17,371 patients were included during the 39-month period, 17,198 (99.0%) had taken at least one of the investigated drugs (median age: 31 years; 23.9% female; ethanol co-ingestion recorded in 41.5%, unknown in 31.2%; multiple drug use in 37.9%). Opioids (in 31.4% of patients) and amphetamines (23.3%) were the most frequently involved and hallucinogens (1.9%) and ketamine (1.7%) the least. Overall, female patients were younger than males, both in the whole cohort (median age 29 vs. 32 years; p < 0.001) and in all drug groups except benzodiazepines (median age 36 vs. 36 years; p = 0.83). The relative proportion of each drug group was different at every age strata and some patterns could be clearly described: cannabis, NPS and hallucinogens were the most common in patients <20 years; amphetamines, ketamine and cocaine in the 20- to 39-year group; GHB/GBL in the 30- to 39-year group; and opioids and benzodiazepines in patients ≥40 years. Ethanol and other drug co-ingestion was more frequent at middle-ages, and multidrug co-ingestion was more common in females than males. CONCLUSION: Differences in the drugs involved in acute drug toxicity presentations according to age and sex may be relevant for developing drug-prevention and education programs for some particular subgroups of the population based on the increased risk of adverse events in specific sex and/or age strata.

The use of lower cut-off values/concentration limits for the calculation of mixture classification in UN GHS/EU CLP versus the previous regulatory scheme (EU Dangerous Preparations Directive, DPD), has resulted in an increased number of classifications in the highest eye hazard category. Herein, a semi-quantitative categorisation of severity of eye effects, following accidental human exposures to detergents, was compared to the classification category of the products. Three schemes were evaluated: EU DPD; EU CLP (based on all available data and information, including weight of evidence); and EU CLP (based entirely on the calculation method). As reported by four EU Poison Centres, the vast majority of exposures had caused minor or no symptoms. Classification was a poor predictor of effects in man subjected to accidental exposure. Note however that this is also because effects are not only driven by the intrinsic hazard (as reflected in the classification), but also by the exposure conditions and mitigation (i.e. rinsing). EU CLP classification using all available data and information was more predictive of medically relevant symptoms than the EU CLP calculation method. The latter led to a poorer differentiation between irritating products versus products potentially causing serious eye damage.

The purpose was to study the prevalence and predisposing factors of brain lesions in survivors of acute methanol poisoning. Clinical data on 106 patients with methanol poisoning were collected during the Czech mass poisoning outbreak. Of 83 survivors, in 46 (55%) patients, follow-up examinations including magnetic resonance imaging of brain (MR) were performed 3-8 and 24-28 months after discharge from the hospital. Of 46 patients with a median age of 49 (interquartile range, 35-57) years, 24 (52%) patients had a total of 40 abnormal brain findings with haemorrhagic lesions detected in 15 (33%) and non-haemorrhagic lesions found in 9 (19%) patients. The patients with haemorrhagic brain lesions were more acidemic (lower arterial blood pH, higher base deficit) and had higher glycaemia and lactacidaemia on admission than those without haemorrhages (all p < 0.05). Thirteen of 32 (41%) of patients with systemic anticoagulation and 2 of 14 (14%) of patients without it had haemorrhagic lesions (p = 0.080). Bleeding complications during the treatment occurred in 4 of 15 (27%) patients, and 5 of 15 (33%) patients had conditions predisposing to haemorrhage in the group with haemorrhagic lesions. In three cases with a series of computer tomography (CT)/MR performed during hospitalization, the necrotic lesions in the brain remained non-haemorrhagic during hospitalization and haemorrhagic lesions were detected on the follow-up MR examinations only. No association between brain haemorrhages and systemic anticoagulation during dialysis was found: brain haemorrhages might occur in severely poisoned patients treated without systemic anticoagulation, whereas treatment with high doses of heparin might not lead to brain haemorrhages.

OBJECTIVES: Paracetamol overdose belongs to frequent calls to Toxicological Information Centre (TIC) in the Czech Republic and to the National Toxicological Information Centre (NTIC) in Slovakia. The aim of the study was to evaluate outcomes and side effects of paracetamol overdose in both countries. METHODS: Data concerning paracetamol poisoning extracted from TIC and NTIC databases 2000-2013 and discharge reports were analysed. Numbers and outcomes in patients presenting within 24 hours of a single paracetamol overdose were compared in relation to 3 paracetamol concentration bands (≤ 100 mg/l, 100-149 mg/l, and 150 mg/l). RESULTS: 5397 inquiries concerning paracetamol were recorded in TIS and NTIC. Data from 196 discharge reports with plasma level were studied. Median age of the patients was 18 (0.2-86) years. Eight/196 (4.1%) patients developed side effects after N-acetylcysteine (NAC) administration. 120 cases fulfilled time criteria of the study and were divided into 3 groups, where 55.7%, 73.1% and 96.9% patients have been treated with NAC. Among these 120 patients, favourable outcome was seen in 100%, 100%, and 92.8%, respectively. One death due to suicidal attempt with plasma level 407 mg/l presenting at 20 hours has been recorded among 120 patients. No patient without NAC treatment died due to acute overdose and plasma concentration ≤ 150 mg/I at 4 hours. CONCLUSIONS: These data support the opinion that NAC should not be used in patients with < 149 mg/l levels in absence of higher risk factors because of very low risk of hepatotoxicity on one side, and side effects on the other side.
