RESUMO

Exposure to chemical substances results in a multitude of poisonings or suspected poisonings every year. Poison centres (PCs) advise the public and medical staff on these issues and register cases in their databases. Additionally, the Federal Institute for Risk Assessment (BfR) maintains a case database with notifications reported by attending physicians within the framework of the Chemicals Act.This article describes important poisons from the field of chemicals and products and gives an example of poisoning risk management for a new product group. For this purpose, exemplary case information published in the annual reports of different PCs and the cases notified to the BfR were examined.An overview is provided on the product groups leading most frequently to poisonings and requests to the PCs. The spectrum of poisonings registered by the BfR and PCs differs clearly between reporting persons, route of exposure and severity. Substance groups with a relatively high risk compared to other chemical substances and products are highly concentrated detergents, acids and alkalis as well as carbon monoxide.PCs and the BfR databases contain valuable information to estimate the frequency and severity of various poisonings. By merging these data in a national poisoning register, new risks would be discovered more quickly in the future and a national overview of poisoning events would be gained.

RESUMO

Reports on adverse effects of chemical substances and mixtures (poisonings in the broader sense) are of great importance both for the improvement of medical care as well as for substance and product safety and for medical education and training. Case reports are the basis of toxicovigilance, i.e. the detection and assessment of poisoning risks in a community arising from clinical cases. Reports on poisonings are created mainly by medical doctors, but also by toxicologically trained nurses and non-medical scientists of poison centres and toxicology labs.In this article, basic terms of clinical toxicology are explained and the important roles of reporting on poisoning are described.Standards for poisoning reporting are partly developed. Reports differ in structure, information content and the degree of assignment of evaluation categories (administrative, clinical, product safety, e.g. agent group, degree of poisoning severity, causality). Methodologically, a distinction is made between detailed individual case reports and aggregated case series with little clinical information.As a result, case reports have recently been used to describe novel intoxications (e.g. new psychoactive substances [NPSs]). Case series facilitated the detection of poisoning outbreaks (sealant spray, ciguatera fish poisoning) and novel products with increased risk of poisoning (e.g. liquid laundry detergent capsules). Systematic toxicovigilance at the national level in Germany will be considerably improved by a national register of poisoning planned at German Federal Institute for Risk Assessment (BfR). For a European toxicovigilance scheme, the recently developed EuPCS product category system forms an important basis.

RESUMO

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.

RESUMO

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.

RESUMO

As a result of decentralized and non-harmonized documentation of poisoning cases within Germany, in comparison to other countries (e.g. the USA, Switzerland, Sweden, and the Netherlands), there is a substantial lack of harmonized national data, in particular for the early detection and risk assessment at the German Federal Institute for Risk Assessment (BfR).The establishment of a national monitoring system for poisonings in Germany is therefore an important step towards enabling faster and more efficient technical access to consolidated accumulated national poisoning data. Additionally, the monitoring would consolidate the publication of annual reports (modelled on the USA National Poison Data System reports) of the German Poison Information Centres and the BfR. Timely assessment of poisoning cases enables fast recognition and confirmation of acute as well as previously unrecognized poisoning hazards. Also relevant here is the safety of products and the associated protection, especially of children, against poisoning accidents.The continuous monitoring and reporting requirements of such a system necessitate additional and challenging work, suitable human resources and IT infrastructure and an annual budget that must be taken into consideration for overall as well as financial planning.

RESUMO

INTRODUCTION: In the past eight years, the European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) has been intensively involved in a European Commission led process to develop EU legislation on the information of hazardous products that companies have to notify to EU Poisons Centres (or equivalent "appointed bodies"). As a result of this process, the Commission adopted Regulation (EU) No 2017/542, amending the CLP Regulation by adding an Annex on harmonised product submission requirements. Harmonised mixture information requirements: Detailed and consistent information on the composition of the hazardous product will become available to EU Poisons Centres (PC). The information will be submitted by companies to PCs (or equivalent "appointed bodies") using a web-based software application or in-house software. Two new important features are introduced. Firstly, to be able to rapidly identify the product formula, a Unique Formula Identifier (UFI) on the product label links to the submitted information. Secondly, for better comparability of reports on poisonings between EU member states, a harmonised Product Categorisation System will specify the intended use of a product. Rapid product identification and availability of detailed composition information will lead to timely and adequate medical intervention. This may lead to considerable reduction in healthcare costs. Additionally, for companies trading across the EU, costs of submission of this information will be reduced significantly. Next steps: From 2017, an implementation period has started, consisting of a three-year period for stakeholders to implement the new requirements, followed by a gradual applicability for consumer products (2020), professional products (2021) and industrial use-only products (2024). Technical tools to generate the electronic format and the UFI together with guidance documents are expected to be made available by the end of 2017 by the European Chemicals Agency (ECHA). Guidance on interpretation of legal text and ECHA helpdesk support are planned to be ready at the end of 2018.

RESUMO

BACKGROUND: Illnesses caused by exposure to extracorporeal artificial substances play a major role in emergency medicine, family medicine, and environmental medicine. OBJECTIVE: The current situation of medical poisoning management and national reporting of poisonings in Germany are described. MATERIALS UND METHODS: The information and data presented here are derived from a literature review and from stakeholder interviews. RESULTS AND CONCLUSION: Eight poison centres (PCs) offer consultation supporting the diagnosis and treatment of poisoning cases in Germany today. Furthermore, those affected, their relatives and first aiders contact these German PCs, mainly because of a suspected poisoning. German PCs are also contacted by those affected and by institutions in other situations when expert toxicological judgement is needed, especially in cases with an environmental background. Often, interpretation of analytical laboratory results of body fluid samples or environmental samples are requested, or reference to environmental medicine treatment facilities is made. The PCs and the German Federal Institute for Risk Assessment (BfR) cooperate on the national reporting of the risks of poisoning for the population. In addition, the BfR collects and evaluates poisoning reports from German medical doctors that have been directly submitted. A pilot project on a national monitoring of poisonings should collate future case reports. An extensive and current overview of poisonings in Germany is a prerequisite for the identification of unsafe products and to fully comply with the international reporting needs of the German Federal Government in the case of chemical outbreaks and the resulting suspected cases.

RESUMO

CONTEXT: To date, there are no publicly available schemes designed and evaluated specifically for severity assessment of animal poisonings. This poses challenges for the evaluation and comparison of animal poisoning exposure data. OBJECTIVE: Our objective for this pilot study was to evaluate agreement between raters using the Poisoning Severity Score (PSS) and National Poison Data System (NPDS) medical outcome scheme for severity assessment of canine exposures reported to a multistate poison center (PC) and to identify issues regarding their use for severity assessment of animal poisonings. Agreement between both schemes was also assessed. METHODS: The first 196 canine exposures reported to a multistate PC between 1 January and 31 August 2016 were selected and initial inquiry data from exposures was scored by four independent raters. Interrater agreement and agreement between the severity systems was calculated using weighted kappa (Κ) (Light's kappa). Reported clinical effects were also described. RESULTS: Interrater agreement for both the PSS (Κ 0.31; 95% CI 0.19, 0.43) and NPDS schemes (Κ 0.34; 95% CI 0.22, 0.44) was low. Agreement between the schemes was slight (Κ 0.05; 95% CI -0.08, 0.16) for pooled results from all four raters. For the PSS, 71.7% (n = 281) of ratings were minor, 23.0% (n = 90) moderate, and 5.4% (n = 21) severe. For the NPDS, 69.6% (n = 273) of ratings were minor, 27.0% (n = 106) moderate, and 3.3% (n = 13) severe. The top three reported clinical effects included vomiting (n = 86, 29.9%) drowsiness/lethargy (n = 38, 13.2%), and diarrhea (n = 24, 8.3%). DISCUSSION AND CONCLUSIONS: This study shows considerable variability between raters using either the PSS or NPDS schemes for canine exposures severity assessment. The subjective nature of the schemes, the influence of intra- and interrater variation, and predominance of minor cases on the study findings should be taken into account when interpreting this data. Further evaluation of these schemes is warranted and could help inform their future use for animal poisoning severity assessment.

RESUMO

OBJECTIVES: European legislation requires reporting from Member States on acute poisoning incidents involving pesticides. However, standard rules for data collection and reporting have not yet been set out. The new categorization system presented in this paper is aimed at enabling Member States to gather comparable data and provide standard reporting on pesticide poisoning exposures. MATERIALS AND METHODS: European Regulations providing separate official categorization of biocidal and plant protection pesticides, were used as a basis to build up a unified pesticide categorization and coding system. Data on selected pesticide exposures collected by Poison Control Centres in six EU countries were reviewed, categorized and reported according to the proposed system. RESULTS: The resulting pesticide categorization system has two dimensions. The first part identifies the main category of use, i.e. biocide/plant protection pesticide/unknown, and the secondary category of use, e.g. Rodenticides, Insecticides and acaricides. The second part of the system is organized into two levels: level one identifies chemical grouping, e.g. Coumarins, Pyrethrins/pyrethroids, while level two identifies the active compound by using its Chemical Abstract Service Registry Number. The system was used to provide a unified categorization to compare exposures to plant protection and biocidal Rodenticides and Pyrethrins/pyrethroids Insecticides and acaricides identified by six EU member states. CONCLUSION: The developed pesticide categorization system was successfully applied to data extracted from different databases and was able to make the required information comparable. The data reported filling in common templates containing a pre-ordinate list of active compounds categorized according the proposed system, highlighted different capabilities in data collection and recording, showing that some of the collaborating centres were not able to distinguish between main categories of pesticide products or provide information on active compounds. The results indicate that a special effort should be dedicated to support detailed data recording at national level. Providing common tools to systematically report to the EU Commission hazardous exposures to pesticides, as well as to other selected categories of products, could allow for data comparability between Member States and greatly improve post marketing surveillance and alerting systems in Europe.

RESUMO

Non-targeted screening of body fluids for psychoactive agents is an essential task for forensic toxicology. The challenge is the identification of xenobiotics of interest from background noise and endogenous matrix components. The aim of the present work was to evaluate the use of an Automated Mass Spectral Deconvolution and Identification System (AMDIS) for gas chromatography-mass spectrometry (GC-MS) based toxicological serum screening. One hundred fifty serum samples submitted to the authors´ laboratory for systematic forensic toxicological analysis underwent GC-MS screening after neutral and basic liquid-liquid extraction. Recorded datasets were routinely evaluated both by experienced personnel and automatically using the AMDIS software combined with the Maurer/Pfleger/Weber GC-MS library MPW_2011. The results from manual and automated data evaluation were then systematically compared. AMDIS parameters for data deconvolution and substance identification had been successfully adapted to the GC-MS screening procedure in serum. The number of false positive hits could substantially be reduced without increasing the risk of overlooking relevant compounds. With AMDIS-based data evaluation, additional drugs were identified in 25 samples (17%) that had not been detected by manual data evaluation. Importantly, among these drugs, there were frequently prescribed and toxicologically relevant antidepressants and antipsychotic drugs such as citalopram, mirtazapine, quetiapine, or venlafaxine. For most of the identified drugs, their serum concentrations were in the therapeutic or subtherapeutic range. Thus, our study indicated that automated data evaluation by AMDIS provided reliable screening results. Copyright © 2015 John Wiley & Sons, Ltd.

RESUMO

Ciguatera is a seafood-borne illness caused by consumption of tropical fish contaminated with ciguatoxins, lipophilic polyethers that are produced in benthic dinoflagellates and accumulate through the marine food chain. Ciguatera cases in Europe usually occur in travellers returning from tropical and subtropical regions of the Pacific and Carribean, where ciguatera is endemic. In 2012, several cases of ciguatera occurred in Germany due to sale of contaminated fish products originating from the Indian Ocean. Although the symptomatology in these cases were typical of ciguatera, with patients reporting gastrointestinal discomfort including nausea, vomiting and diarrhea as well as neurological effects including widespread intense pruritus, paresthesias, hypothermia or altered temperature sensation and diffuse pain, correct diagnosis was delayed in all cases due to lack of awareness of the treating medical practitioners. In light of increasing global mobility, trade, and occurrence of ciguatoxic fish in previously non-endemic areas, ciguatera should be considered as a possible diagnosis if gastrointestinal and neurological symptoms occur shortly after consumption of fish.

RESUMO

Toxin-producing microalgae are thriving worldwide due to coral reef destruction and global warming with major consequences on ecosystems, international trade and human health. Microalgae belonging to the family of flagellate protists, in particular dinoflagellates, secrete a variety of high-molecular-weight polyether toxins that accumulate through the marine food chain to cause disease in humans by acting as sodium channel activator toxins; ciguatera is the most frequent seafood-borne illness worldwide with 50,000 to 500,000 global incidences per annum and is usually limited to endemic areas located between 35° northern and 35° southern latitude. The rising global incidence frequency renders it a major human health problem, because no curative treatment is available yet and reliable detection assays are lacking. During the last decade ciguatera has increasingly become endemic in previously unaffected areas for two reasons: first global warming has contributed to the emergence of dinoflagellate species in subtropical and even temperate regions that previously had been constrained to tropical areas and second: in Europe globalization of fishing industry and tourism has led to a progressive increase in the number of ciguatera cases and a lack of awareness among medical personnel contributes to under-reporting. We review, through a recent ciguatera outbreak in Germany, the risk for ciguatera poisoning in Europe and highlight characteristic symptoms, current knowledge about disease pathomechanisms and treatment options.

RESUMO

There is a need of guidance on how local irritancy data should be incorporated into risk assessment procedures, particularly with respect to the derivation of occupational exposure limits (OELs). Therefore, a board of experts from German committees in charge of the derivation of OELs discussed the major challenges of this particular end point for regulatory toxicology. As a result, this overview deals with the question of integrating results of local toxicity at the eyes and the upper respiratory tract (URT). Part 1 describes the morphology and physiology of the relevant target sites, i.e., the outer eye, nasal cavity, and larynx/pharynx in humans. Special emphasis is placed on sensory innervation, species differences between humans and rodents, and possible effects of obnoxious odor in humans. Based on this physiological basis, Part 2 describes a conceptual model for the causation of adverse health effects at these targets that is composed of two pathways. The first, "sensory irritation" pathway is initiated by the interaction of local irritants with receptors of the nervous system (e.g., trigeminal nerve endings) and a downstream cascade of reflexes and defense mechanisms (e.g., eyeblinks, coughing). While the first stages of this pathway are thought to be completely reversible, high or prolonged exposure can lead to neurogenic inflammation and subsequently tissue damage. The second, "tissue irritation" pathway starts with the interaction of the local irritant with the epithelial cell layers of the eyes and the URT. Adaptive changes are the first response on that pathway followed by inflammation and irreversible damages. Regardless of these initial steps, at high concentrations and prolonged exposures, the two pathways converge to the adverse effect of morphologically and biochemically ascertainable changes. Experimental exposure studies with human volunteers provide the empirical basis for effects along the sensory irritation pathway and thus, "sensory NOAEChuman" can be derived. In contrast, inhalation studies with rodents investigate the second pathway that yields an "irritative NOAECanimal." Usually the data for both pathways is not available and extrapolation across species is necessary. Part 3 comprises an empirical approach for the derivation of a default factor for interspecies differences. Therefore, from those substances under discussion in German scientific and regulatory bodies, 19 substances were identified known to be human irritants with available human and animal data. The evaluation started with three substances: ethyl acrylate, formaldehyde, and methyl methacrylate. For these substances, appropriate chronic animal and a controlled human exposure studies were available. The comparison of the sensory NOAEChuman with the irritative NOAECanimal (chronic) resulted in an interspecies extrapolation factor (iEF) of 3 for extrapolating animal data concerning local sensory irritating effects. The adequacy of this iEF was confirmed by its application to additional substances with lower data density (acetaldehyde, ammonia, n-butyl acetate, hydrogen sulfide, and 2-ethylhexanol). Thus, extrapolating from animal studies, an iEF of 3 should be applied for local sensory irritants without reliable human data, unless individual data argue for a substance-specific approach.

RESUMO

BACKGROUND: In 2011, German hospitals treated approximately 205 000 patients suffering from acute poisoning. Change is seen over time both in the types of poisoning that occur and in the indications for specific treatment. METHODS: This article is based on a selective review of the literature, with special attention to the health reports of the German federal government, the annual reports of the GIZ-Nord Poisons Center (the poison information center for the four northwestern states of Germany, i.e. Bremen, Hamburg, Lower Saxony and Schleswig-Holstein), and the recommendations of international medical associations. RESULTS: From 1996 to 2011, the GIZ-Nord Poisons Center answered more than 450 000 inquiries, most of which involved exposures to medical drugs, chemicals, plants, foods, or cosmetics. Poisoning was clinically manifest in only a fraction of these cases. Ethanol intoxication is the commonest type of acute poisoning and suicide by medical drug overdose is the commonest type of suicide by poisoning. Death from acute poisoning is most commonly the result of either smoke inhalation or illegal drug use. Severe poisoning is only rarely due to the ingestion of chemicals (particularly detergents and cleaning products), cosmetics, or plant matter. Medical procedures that are intended to reduce the absorption of a poison or enhance its elimination are now only rarely indicated. Antidotes (e.g., atropine, 4-dimethylaminophenol, naloxone, toluidine blue) are available for only a few kinds of poisoning. Randomized clinical trials of treatment have been carried out for only a few substances. CONCLUSION: Most exposures to poisons can be treated with general emergency care and, if necessary, with symptomatic intensive-care measures. Poison information centers help ensure that cases of poisoning are dealt with efficiently. The data they collect are a useful aid to toxicological assessment and can serve as a point of departure for research projects.

RESUMO

Recent proof-of-principle data showed that the haematopoietic growth factor granulocyte colony-stimulating factor (filgrastim) mediates neuroprotection in rodent models of Parkinson's disease. In preparation for future clinical trials, we performed a preclinical characterization of a pegylated derivative of granulocyte colony-stimulating factor (pegfilgrastim) in the mouse 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine model of Parkinson's disease. We determined serum and cerebrospinal fluid drug levels after subcutaneous injection. A single injection of pegfilgrastim was shown to achieve stable levels of granulocyte colony-stimulating factor in both serum and cerebrospinal fluid with substantially higher levels compared to repetitive filgrastim injections. Leucocyte blood counts were only transiently increased after repeated injections. We demonstrated substantial dose-dependent long-term neuroprotection by pegfilgrastim in both young and aged mice, using bodyweight-adjusted doses that are applicable in clinical settings. Importantly, we found evidence for the functionally relevant preservation of nigrostriatal projections by pegfilgrastim in our model of Parkinson's disease, which resulted in improved motor performance. The more stable levels of pegylated neuroprotective proteins in serum and cerebrospinal fluid may represent a general advantage in the treatment of chronic neurodegenerative diseases and the resulting longer injection intervals are likely to improve patient compliance. In summary, we found that pegylation of a neuroprotective growth factor improved its pharmacokinetic profile over its non-modified counterpart in an in vivo model of Parkinson's disease. As the clinical safety profile of pegfilgrastim is already established, these data suggest that evaluation of pegfilgrastim in further Parkinson's disease models and ultimately clinical feasibility studies are warranted.

RESUMO

Two previously healthy women developed nausea, vomiting, headache and dizziness for several days, a massive hair loss about 2 weeks later and a discoloration of the fingernails. Detailed diagnostic procedures did not reveal any pathological results. Therapeutic measures did not show any effect. Thallium and arsenic were within normal range in plasma. Delayed quantitative determination of selenium in blood, however revealed toxic values (in case I: 479 microg/L of serum, 8 weeks after ingestion, and in case II 300 microg/L of serum, 9 weeks after ingestion).

RESUMO

INTRODUCTION: The presence of exotic, and sometimes venomous, pets in European homes is becoming more common. This phenomenon is the basis of a French-German cooperative evaluation of the species causing the injuries and the circumstances, severity, and treatment of the envenomations METHODS: A retrospective, descriptive, cross-sectional, case series of data from 1996 to 2006. The study sample consists of all cases of bites and stings by exotic pets that were registered at four poisons European poisons centers. The inclusion criteria were bites and stings of human beings. RESULTS: From 1996 to 2006 four poisons centers in Europe were consulted on 404 bites and stings by exotic pets. The average age of the patients was 36 (2 to 75) years and 73% of the patients were male. The severity of the envenomations, according to the Poisoning Severity Score, was as follows: 29 severe (7.1%), 55 moderate (14.2%) and 320 minor (78.7%). There were no fatalities in this case series. Exotic snakebites from rattlesnakes, cobras, mambas, and other venomous snakes caused 39% of envenomations, aquatic animals (mostly lionfish of the Pterois genus and stingrays) caused 30% of envenomations and arthropods (tarantulas and scorpions) caused 27% of envenomations. All severe envenomations were caused by venomous snakes. CONCLUSIONS: European healthcare professionals may encounter patients bitten or stung by exotic pets. Poisons center consultation can help manage these unusual presentations and help obtain rarely used antivenoms.
