[Poisoning by exotic pets]. / Vergiftungen durch exotische Haustiere.

Exotic poisonous animals such as snakes, marine animals, spiders, and scorpions are a rarity in Central Europe, but are kept as pets by some people. Poisoning caused by these animals is a particular challenge in medical care.Over a period of six years (2001-2006), a total of 202 cases of poisoning with exotic animals were registered and evaluated at four poison information centers in Germany and France. Of the accidents, 91% happened in the home environment; the rest in pet stores. The poisonings were caused by snakes (38%), marine animals (31%), arthropods (spiders and scorpions, 27%), and other poisonous animals (4%). Severe poisoning was involved in 8% of the cases, all caused by snake bites. The severe poisonings were in the form of coagulopathies, severe local symptoms, and a respiratory insufficiency requiring intubation. In six cases of severe poisoning, an immune serum (antivenom) was administered and in three cases a surgical procedure was needed. Deaths did not occur.After the bite of a poisonous animal, the affected limb should usually be immobilized and disinfected, but not tied, cut, or sucked. The exact biological name of the species should be identified. In addition to hospitalization, it is recommended to consult a poison information center.

Effect of new legislation in Germany on prevalence and harm of synthetic cannabinoids.

CONTEXT: New psychoactive substances (NPS) have become an ongoing threat to public health. To prevent the emergence and spread of NPS, a new German law, the 'NpSG' took effect in November 2016. This study presents an overview of analytically confirmed synthetic cannabinoid (SC) intoxications from January 2015 to December 2018. In order to demonstrate effects of the NpSG, the results of 23 month before and 25 month after the introduction of the law were compared. METHODS: Within the scope of a prospective observational study blood and urine samples were collected from emergency patients with suspected NPS intoxication. Comprehensive drug analyses were performed by LC-MS/MS analysis. RESULTS: In the period considered, 138 patients were included. Within these, SC intake was verified in 65 patients (73%) in the period before the law change, and in 30 patients (61%) after. The median age increased significantly from 19.5 to 26 years. Seizures and admission to the ICU were reported significantly less frequently (seizures 29% versus 6.7%, p = 0.0283; ICU admission 42% versus 13%, p = 0.0089). 34 different SCs were detected, including four SCs (Cumyl-PEGACLONE, 5 F-MDMB-P7AICA, EG-018, 5 F-Cumyl-P7AICA) not covered by the NpSG at the time of detection. In the first period the most prevalent SC was MDMB-CHMICA (n = 24). 5 F-ADB was the most prevalent SC overall, detected in 7 patients (11%) in the first, and in 24 patients (80%) in the second period. CONCLUSION: The number of SC intoxications decreased overall after the implementation of the NpSG. The shift in the detected SCs can be considered a direct effect of the NpSG but unfortunately the market supply does not appear to have been reduced. Although changes in the age distribution and in the severity of intoxications may be seen as secondary effects of the law, the main objectives of the new law to prevent the emergence and spread of further chemical variations of known scheduled drugs, have apparently not been achieved from the perspective of this study.

[Carbon monoxide poisoning from indoor barbecues--incidents reported to the German-speaking Poison Information Centers and the German Federal Institute for Risk Assessment (BfR) in Berlin]. / Kohlenmonoxidvergiftungen durch Grillen in Innenräumen--Mitteilungen an die deutschsprachigen Giftinformationszentren und das Bundesinstitut für Risikobewertung Berlin.

From 2008 to the end of 2009 the Joint Poison Information Center (PIC) in Erfurt observed 7 incidents involving 17 persons (1 fatality) with signs of carbon monoxide poisoning from indoor barbecues (COFIB). To find out whether COFIB is a regional or a general phenomenon in Germany, Austria and Switzerland, all information about COFIBs recorded by the 11 German-speaking Poison Information Centers and the BfR Berlin were retrospectively analyzed for the period 2000 to 2009. In all, 60 COFIBs (accidental: 90.0 %, suicidal: 8.3%, reason unknown: 1.7%) involving 146 individuals were reported. The number of incidents increased from one case with 2 persons in 2000 to 18 cases involving 34 persons in 2009. The 146 victims (female 26.7%, male 27.4%, gender unknown 45.9%; adults 58.2%, children 24.7%, age unknown 17.1%) lived in 15 of the 16 federal states of Germany and in Switzerland. The highest number of victims was found in Bavaria (23), Brandenburg (18), and Baden-Wuerttemberg (18). The symptoms according to the Poisoning Severity Score were none to mild in 60.3%, moderate in 13.7%, severe in 11.6%, fatal in 6.9% and unratable in 7.5%. No clear correlation was found between the carboxyhemoglobin concentration and the severity of the symptoms. As a rising number of COFIBs often involving several individuals was observed from 2000 to 2009, the general public was informed about the risks of indoor barbecues.

Intox, detox, antidotes - Evidence based diagnosis and treatment of acute intoxications.

BACKGROUND AND AIM: Aim of this review is to describe the role of clinical toxicology in the context of acute medicine. A special focus is put on antidotes and important aspects of diagnosis and therapy of acute intoxications. The data of the annual report of GIZ-Nord Poisons Centre is analyzed concerning the following aspects: what intoxications are relevant in acute medicine, are there special aspects in therapy, e.g. antidotes, and what antidotes are relevant? More over intoxication-related fatalities are analyzed. RESULTS AND CONCLUSION: In 2015 the poisons centre was consulted in 33,000 cases of acute intoxications. The most important groups are drugs (e.g. antidepressants, beta blockers and calcium channel blockers), chemical products (e.g. products containing surfactant, corrosive substances and toxic alcohols like methanol), plants and recreational drugs. Intoxications are relevant in acute medicine. Some substances can cause fatal intoxications. Important antidotes are naloxone for opiods, acetylcystein for paracetamol, fomepizole and ethanol for toxic alcohols and diazepam for intoxications caused by chloroquine.

Toxicological investigation of forensic cases related to the designer drug 3,4-methylenedioxypyrovalerone (MDPV): Detection, quantification and studies on human metabolism by GC-MS.

3,4-methylenedioxypyrovalerone (MDPV) is a synthetic cathinone belonging to the class of α-pyrrolidinophenones that become increasingly popular as a designer psychostimulant. Here, we report a comprehensive collection of MDPV exposure with quantitative serum level confirmation in Germany. During the years 2014-2016, we could proof consumption of MDPV in 23 cases where urine and blood samples were submitted to our laboratory by the police of Lower Saxony. Most of the samples underwent systematic toxicological analysis by gas chromatography-mass spectrometry (GC-MS), where MDPV could be detected in urine and/or serum samples. The determined concentrations of MDPV in serum showed a high variability, ranging from traces (<10ng/mL) up to 576ng/mL with a mean concentration of 118ng/mL and median of 47ng/mL. The majority of MDPV users were men (87%) and the age ranged from 23 to 49 years (mean 35.9, median 37 years). For most of the analytically confirmed MDPV cases we could prove co-consumption of other psychotropic drugs with frequent occurrence of opiates and cannabinoids in 22% of the cases, followed by benzodiazepines and cocaine in 17%. Analysis of urine samples by GC-MS disclosed the presence of MDPV and its metabolites 2'-oxo-MDPV, demethylenyl-MDPV, demethylenyl-methyl-MDPV, demethylenyl-oxo-MDPV, demethylenyl-methyl-oxo-MDPV and demethylenyl-methyl-N,N-bisdealkyl-MDPV. The metabolite pattern substantiates previous suggestions for principle metabolic pathways of MDPV in humans.

[Imported tropical fish causes ciguatera fish poisoning in Germany]. / Vergiftung durch Tropenfisch: Ciguatera-Epidemie in Deutschland.

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.

Ciguatera fish poisoning: a first epidemic in Germany highlights an increasing risk for European countries.

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.

Bites and stings by exotic pets in Europe: an 11 year analysis of 404 cases from Northeastern Germany and Southeastern France.

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.

Surgical treatment in cocaine body packers and body pushers.

OBJECTIVE: Body packers smuggle cocaine by swallowing containers filled with the drugs, whilst body pushers conceal the containers in the rectum or vagina. In a collaborative effort between the Department of General Surgery, two major airports and Poisons Centre, we performed a retrospective study to develop an algorithm for the treatment of ruptured cocaine-filled containers. MATERIALS AND METHODS: The data of all cocaine body packers and body pushers who were identified at the airports of Frankfurt and Paris from 1985 to 2002 were evaluated concerning incidence, demographics and surgical aspects. RESULTS: From 1985 to 2002, 312 body pushers and 4,660 body packers were identified. The sex ratio was 1:1. Sixty-four "mules" (1.4%) developed life-threatening symptoms of cocaine overdose after the rupture of a container. In 20 patients, an emergency laparotomy was performed and the containers were removed; all of these patients survived. Forty-four body packers died before surgical treatment could be performed. Only one body pusher required medical attention. CONCLUSION: Cocaine overdose can be life-threatening. If the cause is the rupture of a container in a body packer, the only possible treatment is immediate laparotomy for the removal of the container.

Rattlesnake bites in Europe--experiences from southeastern France and northern Germany.

INTRODUCTION: Rattlesnakes are indigenous to the New World and hence their envenomations are a significant percentage of all poisonings in North and South America. Some years ago rattlesnake bites were virtually unknown in Europe. But the biodiversity of European household fauna has changed: cats and dogs are increasingly replaced by stingrays, tarantulas, fire fish, and rattlesnakes. This phenomenon is the background of a French-German cooperation to evaluate the relevance of rattlesnake bites for European doctors. MATERIAL AND METHODS: In a retrospective study all consultations of the GIZ-Nord poison centre in Göttingen and the Centre Antipoison in Marseille concerning bites of poisonous snakes in a 20-yr time period were analyzed. RESULTS: Altogether 671 cases of poisonous snake bites were registered. Rattlesnake bites came up to 21 (3.1% of all consultations due to poisonous snake bites). Over the years the number increased constantly. All patients were adult men with a mean age of 37.2 (20-64) years. There were no females and no pediatric patients involved. According to the Poisoning Severity Score there were 8 minor, 5 moderate, and 8 severe envenomations; no fatalities. The leading clinical symptoms consisted of rhabdomyolysis, neurological, and coagulational disorders. In 5 cases antivenom therapy was applied, and in 4 patients surgical therapy was performed. CONCLUSION: Rattlesnake bites are rare in Europe, but the incidence is rising. The patients' profile is different from large American case series. European doctors should be aware of the increase in these infrequent envenomations.
