Background: Inquiries about fruit plants are a frequent reason for consultation with poison information centers, although it should be emphasized that there are no large systematic studies on toxicity based on exposure data. The aim of this work is to determine the risk of poisoning by fruit plants in Germany., Methods: Retrospective study of data from the Erfurt Joint Poison Information Center on poisoning inquiries regarding fruit plants (2010-2019) with a detailed presentation of interim results, a tabular handout, plant photos as identification aids, and trend analyses., Results: From 16,088 plant exposures with 16,700 plants, 214 different fruit plant species were identified. Forty-five fruit plant species (21%) turned out to be relevant (≥ 30 inquiries) and of these, 6 (2.8%) turned out to be highly relevant (≥ 300 inquiries). All relevant plants were assigned a defined risk category (RC): RC 0 (2; 4.4%), RC 1 (26; 57.8%), RC 2 (12; 26.7%), and RC 3 (5; 11.1%). Regarding the inquiries, 6% (459/7607) were related to RC 0; 47.9% (3645/7607) to RC 1; 39.3% to RC 2 (2986/7607); and 6.8% (517/7607) to RC 3. Of the inquiries, 69.5% (5284/7607) were related to young children (1 to < 6 years). Exposure outcomes for all age groups were asymptomatic in 82%, mild in 14.7%, moderate in 3%, and severe in 0.3%, with severe poisoning caused by seven plant species. Interventions were initiated in 66.8% (5079) of the inquiries. Inquiries were most frequently related to Taxus baccata, Ligustrum vulgare, Physalis alkekengi, Prunus laurocerasus, Convallaria majalis, Mahonia spec., Sambucus spec., Lonicera spec., Sorbus aucuparia, Thuja spec., Hedera helix, and Cotoneaster spec., Discussion: Poisoning by fruit plants in Germany is rare. However, there is a great need for information and education., (© 2023. The Author(s).)

Aim of the Study: Because of significant changes in recent years, cases of illicit drug exposure reported to the Poisons Information Centre (PIC) Erfurt during the last 10 years were investigated., Methods: Retrospective analysis of above-mentioned cases from 2011 to 2020 according to substance classes, symptom severity, age groups, and gender., Results: Cases of illicit drug exposure (4,963, 2.8% of all exposures) increased from 316 in 2011 to 614 in 2015, decreased to 514 in 2017, and rose again to 578 in 2019. In 2020, a drop to 549 cases was observed. The ratio of multiple to single drug exposure cases, however, increased from 1.0 to 1.7 in 2020. Cases of exposure to psychostimulants almost doubled from 168 in 2011 to 319 in 2020. Cases of exposure to new psychoactive substances (NPS) rose from 21 in 2011 to 126 in 2015 and fell to 16 in 2020. 320 cases (6.5%) of illicit drug exposures resulted in severe, 1902 cases (38.3%) in moderate and 2139 cases (43.1%) in minor or no symptoms. Age groups mainly involved were adults of middle age (72.7%) and unknown age (12.7%) as well as adolescents (12.1%). Men (69.9%) were more often involved than women (26.9%)., Conclusions: Illicit drug exposures reported to the Poisons Information Centre (PIC) Erfurt discontinuously increased from 2011 to 2020 mainly by increase in mixed consumption. The intermittent decrease in 2016 and 2017 was caused by the fall of NPS exposures. Data of substance abuse from PICs could supplement official annual drug reports in aspects of Clinical Toxicology., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Introduction: Poison Information Centers (PICs) fulfil the legal mandate to provide advice and answer inquiries from healthcare professionals and medical nonprofessionals on measures to be taken in the event of an intoxication. Medication errors might be a frequent cause of intoxication. However, hardly any data on medication errors are available from PICs., Aim: We aimed to investigate the incoming inquiries of a PIC with regard to medication errors., Methods: In the PIC database, we identified and analyzed medication errors in a retrospective analysis of inquiries from 2013 to 2020. We distinguished between medication errors committed by (i) laypersons or by healthcare professionals in (iia) medical care facilities or (iib) home care facilities. We evaluated the estimated potential risk of toxicity to assess the potential harm to the patient., Results: From 152,149 inquiries in total, 43.5% ( n  = 66,229) dealt with drug exposures. We identified medication error in 19.1% ( n  = 12,619) of those inquiries. Of those medication errors, 80.1% ( n  = 10,113) were committed by (i) laypersons and 19.9% ( n  = 2506) were committed by healthcare professionals, with nearly equal proportions occurring in medical care and in home care [(iia) 49.6% and (iib) 50.4%, respectively]. A total of 18,718 drugs were involved, with most medication errors found for ibuprofen, acetaminophen, and levothyroxine. The medication errors led to a minor estimated risk of toxicity in 46.6% (5,877/12,619); moderate and severe risk occurred in 7.0% (886/12,619) and 2.6% (329/12,619), respectively. Medication errors caused by laypersons or healthcare professionals in home care were associated with a lower risk compared to those caused by healthcare professionals in medical care ( p  < 0.001)., Conclusion: This study identified medication errors that were committed mainly by laypersons in almost 80% of the medication inquiries to a PIC. Medication errors caused by healthcare professionals in medical care led to a higher risk of harm to the patients.

Background: Questions on poisoning by plants are a common reason for inquiries to poison information centers (PIC). Over the years 2011-2020, plant poisoning was the subject of 15% of all inquiries to the joint poison information center in Erfurt, Germany (Gemeinsames Giftinformationszentrum Erfurt, GGIZ) that concerned poisoning in children (2.3% in adults). In this patient collective, plant poisoning occupied third place after medical drugs (32%) and chemical substances (24%), and was a more common subject of inquiry than mushroom poisoning (1.5%)., Methods: This review is based on pertinent publications retrieved by a selective literature search in PubMed/TOXLINE on plant poisoning and on 12 epidemiologically and toxicologically relevant domestic species of poisonous plants in risk categories 2 and 3 (up to 2021)., Results: Medical personnel should have basic toxicological knowledge of the following highly poisonous plants: wolfsbane (aconitum), belladonna, angel's trumpet, cowbane (cicuta virosa), autumn crocus, hemlock, jimson weed, henbane, castor bean (ricinus), false hellebore, foxglove (digitalis), and European yew. The intoxication is evaluated on the basis of a structured history (the "w" questions) and the clinical manifestations (e.g., toxidromes). Special analysis is generally not readily available and often expensive and time-consuming. In case of poisoning, a poison information center should be contacted for plant identification, risk assessment, and treatment recommendations. Specimens of plant components and vomit should be obtained, if possible, for further testing. Measures for the elimination of the poisonous substance may be indicated after a risk-benefit analysis. Specific antidotes are available for only a few types of plant poisoning, e.g., physostigmine for tropane alkaloid poisoning or digitalis antibodies for foxglove poisoning. The treatment is usually symptomatic and only rarely evidence-based. Individualized medical surveillance is recommended after the ingestion of large or unknown quantities of poisonous plant components., Conclusion: The clinician should be able to recognize dangerous domestic species of poisonous plants, take appropriate initial measures, and avoid overdiagnosis and overtreatment. To improve patient care, systematic epidemiological and clinical studies are needed.

Psycholeptics, psychoanaleptics, and cardiovascular drugs alter individual tolerance to extreme heat. To explore the influence of heat waves on their toxicity in acute overdose, we retrospectively analyzed all human exposures to psycholeptics and psychoanaleptics (PLAexp) as well as cardiovascular drugs (CVDexp) registered by the Poisons Information Center (PIC) Erfurt between June to September of the years 2003 to 2018 for frequency, age groups, sex, circumstances of exposure, and symptom severity. The results of the non-heat years (NHY) 2004-2005 and 2007-2014 (average air temperature June-September 16.2 °C) were compared to the results of the heat years (HY) 2003, 2006 and 2015-2018 (average air temperature June-September 17.5 °C). In total, 13,191 cases (HY 5,117; NHY 8,074) of PLAexp and 2,960 cases (HY 1,168; NHY 1,792) of CVDexp were registered. During HY, accidental PLAexp (11.2% versus 9.7%) and CVDexp (40.6% versus 36.8%) were more often seen. Severe symptoms were less frequent in PLAexp (4.4% versus 6.3%) and CVDexp (3.3% versus 4.9%). Although in HY, no higher rates of moderate or severe PLAexp and CVDexp were detected than in NHY, patients with these medications should be observed carefully during heat waves because of affected body's usual cooling mechanisms.

We examined human exposures to dental products (EDP), stomatological preparations (ESP), and in the context of dental care (EDC) or toothache (ETA) registered by the Poisons Information Centre (PIC) Erfurt from 1997 to 2017. Dental products like dental technical and filling materials belong to medical devices. Stomatological preparations were classified according to the ATC code and symptom severity to the Poisoning Severity Score (PSS). In total, 156 cases of EDP (136 cases with different tooth filling materials), 1167 cases of ESP (55.6% fluoride containing products), 979 cases of EDC, and 331 cases of ETA were registered. Symptom severity in EDP and ESP were asymptomatic or mild. In ETA and EDC, however, 35 cases with moderate and 5 cases with severe symptoms were detected. 5 moderate and 3 severe cases were caused by prolonged paracetamol overdose. Severe bleeding occurred following tooth extraction in a 41 year-old phenprocoumon treated patient after self-medication with acetylsalicylic acid and metamizole. Gingival injection of lidocaine plus epinephrine in a 37 year-old healthy woman resulted in severe bradycardia and cardiac arrest. Acute toxicity of EDP and ESP appears to be low. Prolonged paracetamol overdose because of toothache, and some dental treatment can result in severe symptoms.

Objective: Local effects on the eye following cleaning product exposures are frequently reported. According to EU chemicals legislation many cleaning products are labelled with Hazard Phrase 318 indicating risk of irreversible eye damage. The objectives of this study were to identify cleaning products with potential for irreversible eye damage by collecting human exposure data from poisons centres (PC), and to clarify to what degree exact product identification is possible during a PC telephone call. Methods: MAGAM II was a multicentre binational prospective observational PC study. All human eye exposures to detergents or maintenance products reported to nine PCs taking calls from the public and medical professionals during an 18-month period were included. The severity of eye effects was rated according to the WHO Poisoning Severity Score. Results: Five hundred and eighty-six cases were included. Product identification by name leading to formula information was successful in 533 cases (91%). Follow-up was successful in 528 exposures. Irrigation was performed in 94% of cases. Duration of symptoms was ≥24 hours in 73 patients (25%). 33 (6%) patients developed moderate eye injury. Healing was reported in all cases. The percentage of moderate cases was highest in the group of drain cleaners (25%), toilet cleaners (18%) and oven cleaners (15%). Products intended for professional use caused relatively more moderate eye injuries than products also intended for consumer use. Conclusion: MAGAM II has shown that PCs are able to identify formulas in sufficiently high quality as needed for product-directed toxicovigilance. The results underline the potential of PC exposure case data for product safety monitoring. The results indicate that irreversible eye damage is very rare after cleaning product exposure.

Background: In 2016, according to the German Federal Statistical Office, 178 425 cases of intoxication (poisoning) were treated in German hospitals. The poison control centers in the German-speaking countries gave advice in a total of 268 787 instances of poisoning in that year, and use of activated charcoal was recommended in 4.37% of cases. The application of activated charcoal plays a major role in both primary and secondary detoxification. This article serves as an overview of the mechanism of action, indications, contraindications, modes of application, and dosing of activated charcoal., Methods: This review is based on pertinent publications retrieved by a selective search in PubMed. The opinions of experts from the poison control centers in the German-speaking countries were considered in the interpretation of the data., Results: The administration of activated charcoal is indicated to treat moderately severe to life-threatening intoxication. It should be carried out as soon as possible, within the first hour of the ingestion; timed-release preparations can be given up to 6 hours after the ingestion. An important contraindication is impaired consciousness with the danger of aspiration in a patient whose air- way has not yet been secured. Activated charcoal is ineffective or inadequately effective in cases of poisoning with acids or bases, alcohols, organic solvents, inorganic salts, or metals. The proper dosage consists of an amount that is 10 to 40 times as much as that of the intoxicating substance, or else 0.5-1 g/kg body weight in children or 50 g in adults. Repeated application is indicated for intoxications with agents that persist for a longer time in the stomach and for intoxications with timed-release drugs or drugs with a marked enterohepatic or entero-enteric circulation. The routine combination of activated charcoal with a laxative is not recommended., Conclusion: Even though intoxications are common, there is still no internationally valid guideline concerning the administration of activated charcoal. A precise analysis of the risks and benefits is needed for each administration, and a poison control center should be consulted for this purpose.

Aim of the Study: Poisoning due to substance abuse has changed significantly during the last few years. Therefore, developments of substance abuse reported to the Poisons Information Centre Erfurt were investigated and compared to other circumstances of human exposures during the last 15 years., Methods: Retrospective analysis of all cases of human exposures (intentional abuse, accidental and unknown circumstances, and suicide attempts) for the period 2002-2016 according to substance classes, reasons of exposures, symptom severity, age groups, and gender., Results: Cases of substance abuse (n=7,237, 3.5% of all exposures) continuously increased from 250 (159 with one and 91 with multiple substances) in 2002 to 830 in 2016 (398 with one and 432 with multiple substances). Cases of exposure to metamphetamine strongly increased from 10 in 2003 to 100 in 2012 and dropped to 52 in 2016. Cases of exposure to new psychoactive substances (NPS) rose from 1 in 2008 to 130 in 2015 and fell to 90 in 2016. Substance abuse significantly (p<0.001) more often caused moderate (29.1%) and severe symptoms (5.8%) than suicide attempts (11.6%; 4.9%). NPS and their subgroup synthetic cannabinoids led significantly (p<0.001 and 0.025) more frequently to moderate and severe symptoms (46.9% and 43.6%; 7.9% and 6.0%) than cannabis exposure (19.7%; 2.1%)., Conclusions: Clinical significance of substance abuse is shown by the fact that it resulted more often in moderate and severe symptoms than suicide attempts. Data of substance abuse from PICs could supplement those on clinical toxicology in official annual drug reports., Competing Interests: Die Autoren erklären, dass kein Interessenskonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim of the Study: Exposures in suicide attempts are demanding for hospitals and poisons information centres (PICs). Therefore, the time characteristics of their frequency were studied. Methods: A retrospective analysis was undertaken of all human exposures reported to Centre Erfurt from the beginning of 2004 to the end of 2013 according to their frequency in the respective year, season, month, weekday, time of the weekday, circumstances of exposure, age and gender. Results: 59.7% of all exposures (n=137 104) were accidental, 23.4% occurred in suicide attempts and 3.3% in substance abuse. 0.3% of the suicide attempts resulted in death. Their number continuously increased from n=2 422 in 2004 to n=3 458 in 2013, but their relative frequency remained almost constant at 23.4%. Their highest numbers were reached in the spring and summer with maxima in July and August and minima in February and September. During the week, the most suicide attempts were observed between Sunday and Tuesday and the least on Friday. Highest rate of suicide attempts was seen at 10 pm and lowest at 6 am. The median of age was 39 years (first quartile 24 years, third quartile 50 years). The female proportion was almost twice as high as the male. Conclusions: Hospitals the Centre Erfurt is serving should be particularly prepared for exposures in suicide attempts in the spring and summer (especially in July and August), at the beginning of the week and shortly before midnight., Competing Interests: Interessenkonflikt:: Die Autoren erklären, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim of the Study: Because of their frequency, non-opioid analgesics (NOA) single drug exposures registered by Poisons Information Centre (PIC) Erfurt have been studied over a decade., Methods: A retrospective analysis of frequencies, circumstances of exposure, symptom severity, and age groups in NOA single drug exposures received by the PIC Erfurt from the beginning of 2003 to the end of 2012 was undertaken., Results: Of all 4749 NOA single drug exposures, the 10 most frequent were caused by paracetamol (n=1 686), ibuprofen (n=1 439), acetylsalicylic acid (n=456), dipyrone (n=274), diclofenac (n=267), flupirtine (n=138), naproxen (n=41), etoricoxib (n=36), indomethacin (n=24), and dexketoprofen (n=19). Paracetamol single drug exposures increased from 158 in 2003 to 216 in 2007 and fell afterwards to 133 in 2012. Ibuprofen single drug exposures continously rose from 57 in 2003 to 258 in 2012. Adults were more often involved in NOA (53.8%) and all single drug exposures (54.1%) than children (45.9% and 45.6%, respectively). Suicidal attempts were more frequent in NOA (43.1%) than in all single drug exposures (34.2%), whereas accidental exposures or exposures in abuse were less often (33.4 and 0.2%, 46.0 and 0.9% respectively). NOA single drug exposures resulted mostly in none to minor symptoms (77.0%) and rarely in moderate (2.1%) or severe symptoms (1.0%). One adult was found dead after probable ingestion of 32 g of acetylsalicylic acid in suicidal intention., Conclusions: Because many NOA are over-the-counter drugs, it is difficult to obtain data on their use. PIC data could provide information on the NOA use in the population., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim of the Study: Because of their importance for clinical toxicology, developments of sub-stance abuse reported to the Poisons Information Centre (PIC) Erfurt were investigated and compared to other reasons of human exposures., Methods: A retrospective analysis of all human exposures (exposures of humans to substances in abuse, accidental and unknown circumstances, and suicide attempts) (n=125,130) from the beginning of 2002 to the end of 2011 was undertaken according to substance classes, reasons of exposures, symptom severity, age groups, and gender., Results: Cases of substance abuse (3,760, 3.0% of all exposures) continuously increased from 252 (92 with one and 160 with multiple substances) in 2002 to 507 in 2011 (239 with one and 268 with multiple substances). In relation to all exposures, only the abuse of multiple substances rose significantly (p<0.001). In comparison to all substances of exposure, ethanol, amphetamine-type stimulants, benzodiazepines/analogues, and liquid ecstasy abuse significantly (p<0.005) increased while cannabis and Brugmansia/Datura species abuse significantly (p<0.05) decreased. Substance abuse significantly (p<0.001) more often caused moderate (23.7%) and severe symptoms (6.1%) than in suicide attempts (9.6%; 4.4%). First legal highs exposures were registered in 2010 and led significantly (p<0.001) more often to moderate symptoms (50%) than cannabis exposures (19.4%)., Conclusions: The clinical significance of substance abuse is shown by the fact that it resulted more often in moderate and severe symptoms than suicide attempts. Data on substance abuse from PICs could supplement official annual drug reports in aspects of clinical toxicology., (© Georg Thieme Verlag KG Stuttgart · New York.)
