Changes in the ecology of macrofungi are poorly understood, not only because much of their life cycle is hidden belowground, but also because experiments often miss real-world complexity and most fruitbody inventories are limited in space and time. The National Poisons Information Centre 'Tox Info Suisse' provides countrywide 24hours/7days medical advice in case of poisonings since 1966. Here, we introduce a total of 12,126 mushroom-related phone calls that were received by Tox Info Suisse between 1966 and 2014...

BACKGROUND: Psychosis can be associated with acute recreational drug and novel psychoactive substance (NPS) toxicity. However, there is limited data available on how common this is and which drugs are most frequently implicated. We describe a European case series of psychosis associated with acute recreational drug toxicity, and estimate the frequency of psychosis for different recreational drugs. METHODS: The European Drug Emergencies Network (Euro-DEN) collects data on presentations to Emergency Departments (EDs) with acute recreational drug and NPS toxicity at 16 centres in ten countries...

Mushrooms are a favourite natural food in many countries. However, some wild species cause food poisoning, sometimes lethal, due to misidentification caused by confusing fruiting bodies similar to those of edible species. The morphological inspection of mycelia, spores and fruiting bodies have been traditionally used for the identification of mushrooms. More recently, DNA sequencing analysis has been successfully applied to mushrooms and to many other species. This study focuses on a simpler and more rapid methodology for the identification of wild mushrooms via protein profiling based on matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS)...

Lethal amanitas (Amanita sect. Phalloideae) are responsible for 90% of all fatal mushroom poisonings. Since 2000, more than ten new lethal Amanita species have been discovered and some of them had caused severe mushroom poisonings in China. However, the contents and distribution of cyclopeptides in these lethal mushrooms remain poorly known. In this study, the diversity of major cyclopeptide toxins in seven Amanita species from Eastern Asia and three species from Europe and North America were systematically analyzed, and a new approach to inferring phylogenetic relationships using cyclopeptide profile was evaluated for the first time...

α-Amanitin and β-amanitin are the main toxins of mushroom poisoning. The application of traditional non-selective adsorbents is not satisfactory in clinical treatment of amanita mushroom poisoning due to lack of specificity adsorption capability of these adsorbents toward amanitin toxins. In the current work, we introduce a novel molecularly imprinted biomimetic adsorbent based on a ligand specificity determinant through surface imprinted strategy. Owing to the expensive price of the amanitin sources, we selected a typical common moiety of α, β-amanitin as specificity determinant to synthesize a template necessary for the preparation of molecularly imprinted polymers (MIPs)...

Mushroom exposures are increasing worldwide. The incidence and fatality of mushroom poisoning are reported to be increasing. Several new syndromes in mushroom poisoning have been described. Rhabdomyolytic mushroom poisoning is one of new syndromes. Russula subnigricans mushroom can cause delayed-onset rhabdomyolysis with acute kidney injury in the severely poisoned patient. There are few reports on the toxicity of R. subnigricans. This report represents the first record of R. subnigricans poisoning with rhabdomyolysis in Korea, describing a 51-year-old man who suffered from rhabdomyolysis, acute kidney injury, severe hypocalcemia, respiratory failure, ventricular tachycardia, cardiogenic shock, and death...

Amatoxins, which are mainly found in Amanita phalloides, Amanita virosa, and Galerina autumnalis, are responsible for the majority of fatal intoxication with green death cap. The intoxication is associated with acute liver failure, which explains the poor prognosis. Acute liver injury is generally preceeded by a gastrointestinal phase with nausea, vomiting and diarrhea. In the course, pre-renal kidney failure due to the associated fluid deficit and fulminant liver failure may occur. General guidelines for the treatment of amatoxin poisoning are yet not available...

Aim of the study: Based on an abundance of information on the internet, psychotropic plants and mushrooms are of increasing relevance as legal and cheap alternatives to other illicit drugs. Due to the lack of a German database, the abuse of selected biogenic drugs using reported exposures to 3 German Poison Information Centres (PICs) was examined. Methods: Information on abuse of biogenic drugs was collected from the German PICs in Berlin, Erfurt and Fribourg (2007-2013). Results: 602 drug abuses were reported to the selected PICs...

A toxic mushroom, Russula subnigricans, causes fatal poisoning by mistaken ingestion. In spite of the potent bioactivity, the responsible toxin had not been identified for about 50 years since its first documentation. Recently, we isolated an unstable toxin and determined the structure. The slow elucidation was partly due to the instability of the toxin and also due to misidentification of R. subnigricans for similar mushrooms. To discriminate genuine Russula subnigricans from similar unidentified Russula species, we searched for a unique chemical marker contained in the mushroom...

CONTEXT: Paralepistopsis acromelalga, formerly known as Clitocybe acromelalga, is a rare poisonous mushroom. The mycotoxins in this mushroom cause symptoms resembling those of erythromelalgia; however, its pathogenesis remains unclear. In this report, a patient who received nicotinic acid treatment for P. acromelalga poisoning and radiological evaluation for erythromelalgia has been presented. Case detail: A 59-year-old woman was hospitalized for redness, swelling, and burning pain in her extremities that rendered difficulty in walking, and a diagnosis of P...

Orellanine (OR) toxin is produced by mushrooms of the genus Cortinarius which grow in North America and in Europe. OR poisoning is characterized by severe oliguric acute renal failure, with a mortality rate of 10%-30%. Diagnosis of OR poisoning currently hinges on a history of ingestion of Cortinarius mushrooms and histopathology of renal biopsies. A key step in the diagnostic approach is analysis of tissues for OR. Currently, tissue-based analytical methods for OR are nonspecific and lack sensitivity. The objectives of this study were: (1) to develop definitive HPLC and LC-MS/MS tissue-based analytical methods for OR; and (2) to investigate toxicological effects of OR in mice...

Automated rRNA intergenic spacer analysis (ARISA), a method of microbiome analysis, was evaluated for species identification of mushrooms based on the specific fragment sizes. We used 51 wild mushroom-fruiting bodies collected in the centre of Hokkaido and two cultivated mushrooms. Samples were hot-air-dried and DNA were extracted by a beads beating procedure. Sequencing analysis of portions of the rRNA gene (rDNA) provided 33 identifications of mushrooms by genus or species. The results of ARISA identification based on the combination of the fragment sizes corresponding to two inter spacer regions (ITS2 and ITS1) of rDNA within±0...

Amatoxins and phallotoxins are toxic cyclopeptides found in the genus Amanita and are among the predominant causes of fatal food poisoning in China. In the treatment of Amanita mushroom poisoning, an early and definite diagnosis is necessary for a successful outcome, which has prompted the development of protocols for the fast and confirmatory determination of amatoxins and phallotoxins in human biological fluids. For this purpose, a simple, rapid and sensitive multiresidue UPLC-MS/MS method for the simultaneous determination of α-amanitin, β-amanitin, γ-amanitin, phalloidin (PHD) and phallacidin (PCD) in human plasma, serum and urine was developed and validated...

The present study was undertaken with a view to improving forensic medical diagnostics of intoxication with poisonous mushrooms in the cases of patients' death in a hospital. A total of 15 protocols of forensic medical examination of the corpses of the people who had died from acute poisoning were available for the analysis. The deathly toxins were amanitin and muscarine contained in various combinations in the death cap (Amanita phalloides) and the early false morels (Gyromitra esculenta and G. gigas). The main poisoning season in the former case was May and in the latter case August and September (93...

Nanotechnology is a most promising field for generating new applications in medicine, although, only few nano products are currently in use for medical purposes. A most prominent nanoproduct is nanosilver. Nano-silver has biological properties which are significant for consumer products, food technology, textiles, and medical applications (e.g. wound care products, implantable medical devices, in diagnosis, drug delivery, and imaging). For their antibacterial activity, silver nanoparticles (Ag NPs) are largely used in various commercially available products...
