Snakebite is an environmental hazard associated with a significant morbidity and mortality. Two main types of toxicity occur due to snakebite, namely vasculotoxicity and neurotoxicity. Neurotoxic snakebites present mainly with bilateral ptosis with dilated pupils and/or difficulty in breathing. Jatropha curcas belongs to the family Euphorbiaceae and is commonly referred to as "Ratanjyot" in Gujarati. It has got many medicinal uses such as anticancerous properties and bio-oil. There are very few cases of its toxicity in adults...

The illicit drug market has rapidly evolved from synthetic cannabinoids to cathinone derivatives and now a new emerging threat of synthetic opioids. These compounds were mostly developed by pharmaceutical companies during drug discovery. The new psychoactive substances are not routinely covered in drug screening and may go undetected. Recently fentanyl analogous, AH-7921, MT-45 and now U-47700 have been encountered in clinical and forensic casework. U-47700 is gaining popularity on drug user forms as a legal alternative to heroin...

"Purple drank" is a dangerous hallucinogenic cocktail commonly used by teenagers, made popular by American rappers and social networks. It combines codeine-based cough syrup, antihistamines such as promethazine, and soda. Unknown by caregivers, it may be responsible for serious neuropsychological complications. We report the effects of this new risky behavior in three patients: a 14-year-old girl and her boyfriend, both found in an initial state of drowsiness, followed by hallucinations and anticholinergic toxidrome; and another teenager whose chronic use led to addiction with increasing doses...

A 39-year-old homeless man was found confused and incoherent after ingesting an estimated total of 200 tablets of various medications. He presented to the emergency department with delirium, tachycardia, clonus and hyperthermia of 38.0°C. His condition worsened rapidly with his temperature rising to 39.9°C despite active cooling. The patient was subsequently sedated, intubated, paralysed and admitted to the intensive care unit, where he remained for 38 days. His initial presentation of a large mixed drug overdose manifested as serotonin syndrome, which had a protracted course complicated by ethanol withdrawal...

BACKGROUND: Dextromethorphan (DXM) in combination with antihistamines and/or pseudoephedrine is widely available as an over-the counter remedy commonly used for relief of colds and cough. In supra-therapeutic amounts, DXM has psychoactive effects. These cough preparations have been adopted by many young users of recreational drugs for these effects. OBJECTIVES: This paper aims to highlight the increasingly prevalent practice of Robotripping, review pharmacokinetic and dynamic data and discuss potential tolerance and withdrawal from the substance as well as treatment modalities...

INTRODUCTION: Stimulant medications are approved to treat attention deficit hyperactivity disorder (ADHD) in children over the age of 6 years. Fatal ingestion of stimulants by children has been reported, although most ingestions do not result in severe toxicity. Lisdexamfetamine dimesylate, a once daily long-acting stimulant, is a prodrug requiring conversion to its active form, dextroamphetamine, in the bloodstream. Based on its unique pharmacokinetics, peak levels of d-amphetamine are delayed...

Acute pesticide poisoning in children is rare but potentially serious. Some clinical patterns (toxidromes) are suggestive of the drug class: cholinergic crisis for organophosphate or carbamate insecticides; neurological syndrome for rodenticides; digestive and respiratory syndrome for herbicides. Treatment is symptomatic and only a few patients are treated with an antidote: atropine and pralidoxime for organophosphate insecticides, vitamin K for anticoagulant rodenticides.

Intentional or accidental intoxications are common in the emergency department, but are not always sufficiently recognised. When intoxication is suspected, the causative agent or combination of agents often remain unclear, making these patients a diagnostic challenge. We present here a 45-year-old woman who was admitted due to altered consciousness. The clinical presentation fitted the anticholinergic toxidrome and an intoxication with venlafaxine (her known prescribed medication) was suspected. Plasma venlafaxine concentrations, however, were very low...

The American Association of Poison Control Centers has continued to report approximately 50,000 telephone calls or 8% of incoming calls annually related to plant exposures, mostly in children. Although the frequency of plant ingestions in children is related to the presence of popular species in households, adolescents may experiment with hallucinogenic plants; and trekkers and foragers may misidentify poisonous plants as edible. Since plant exposures have continued at a constant rate, the objectives of this review were (1) to review the epidemiology of plant poisonings; and (2) to propose a rapid toxidromic classification system for highly toxic plant ingestions for field use by first responders in comparison to current classification systems...

Poisoning is the leading cause of injury-related mortality in the United States. Data suggest that nonmedical use of pharmaceuticals is increasing, along with a proportional increase in subsequent adverse events. The widespread use of illegal drugs contributes to the challenge, because these drugs may produce a wide array of clinical presentations that warrant time-critical recognition and treatment. Common legal and illegal poisonings highlighting clinical presentations in terms of toxidromes as a means of categorically recognizing these emergencies is the focus of this article...

BACKGROUND: The pattern of recreational drug use has changed over the last decade and now includes a multitude of substances sold as "research chemicals" or new psychoactive substances, "NPS". In France, synthetic cathinones emerged in 2008 (while first mentioned by the French police force in 2007 first alerts among users appeared in 2008) and have grown to be popular drugs of abuse. Under the Official Journal dated 11th June 2010, only mephedrone has been listed as narcotics but "designer drugs" have synthesized new substitute cathinones in order to avoid anti-drug laws...

Novel Psychoactive Substances (NPS), sometimes referred to as Legal Highs, are newly available drugs with psychoactive properties that are not currently prohibited by United Nations Drug Conventions. Despite many of these compounds still being 'legal' and readily available via online mail-order companies and high-street 'headshops', their rapid emergence in the UK has been associated with increasing hospital admissions, enquiries on TOXBASE® and fatalities. It is therefore vital that Acute Physicians have a good understanding of the issues in recognizing, investigating and managing patients presenting to the AMU with toxicity due to legal highs...

UNLABELLED: Drug poisoning is a common cause for attendance in the emergency department. Several toxicology centres suggest performing urinary drug screens, even though they rarely influence patient management. STUDY OBJECTIVES: Measuring the impact on patient management, in a University Emergency Department with approximately 40 000 admissions annually, of a rapid urinary drug screening test using specifically focused indications. Drug screening was restricted to patients having a first psychotic episode or cases demonstrating respiratory failure, coma, seizures, a sympathomimetic toxidrome, severe opiate overdose necessitating naloxone, hypotension, ventricular arrhythmia, acquired long QT or QRS >100 ms, and high-degree heart block...

UNLABELLED: We report on two patients who ingested psychoactive scopolamine that was synthesized at home from butylscopolamine (Buscopan®), which is available as over-the-counter antispasmodic in nearly 100 countries worldwide. Patient 1 presented with severe central anticholinergic toxidrome, while patient 2 suffered from minor symptoms. An empty blister of Buscopan® was found in the patients' home, but initially was not suspected to be causative for the observed central anticholinergic symptoms, as Buscopan® is not able to pass the blood-brain barrier in its native form...

Hallucinogenic plant poisoning in children is a significant problem for the emergency physician. We describe the case of a boy who had slurred speech, fever, hallucinations, tachycardia, dilated pupils, confusion and disorientation. He had no history of drug use or toxin intake. All signs and symptoms were improved by supportive therapy within 48 hours. It turned out that the patient had ingested seeds of Datura stramonium in a neighbor's garden two days previously. The medical history should be taken repeatedly in cases of unknown etiology, and physicians should keep in mind the possibility that unexplained anticholinergic toxidromes could be the result of exposure to toxic plants, in particular those containing atropine and atropine derivates...

BACKGROUND: New psychoactive substances (NPSs) are substitutes for classical drugs of abuse and there are now compounds available from all groups of classical drugs of abuse. During 2014, the number of synthetic cathinones increased dramatically and, together with phenylethylamines, they dominate the NPS markets in the European Union. In total, 31 cathinones and 9 phenylethylamines were encountered in 2014. The aim of this article was to summarize the existing knowledge about the basic pharmacology, metabolism, and human toxicology of relevant synthetic cathinones and phenylethylamines...

Hydrogen sulfide (H2S) is a hazard primarily in the oil and gas industry, agriculture, sewage and animal waste handling, construction (asphalt operations and disturbing marshy terrain), and other settings where organic material decomposes under reducing conditions, and in geothermal operations. It is an insoluble gas, heavier than air, with a very low odor threshold and high toxicity, driven by concentration more than duration of exposure. Toxicity presents in a unique, reliable, and characteristic toxidrome consisting, in ascending order of exposure, of mucosal irritation, especially of the eye ("gas eye"), olfactory paralysis (not to be confused with olfactory fatigue), sudden but reversible loss of consciousness ("knockdown"), pulmonary edema (with an unusually favorable prognosis), and death (probably with apnea contributing)...

Terrorist use of organophosphorus-based nerve agents and toxic industrial chemicals against civilian populations constitutes a real threat, as demonstrated by the terrorist attacks in Japan in the 1990 s or, even more recently, in the Syrian civil war. Thus, development of more effective countermeasures against acute organophosphorus poisoning is urgently needed. Here, we have generated and validated zebrafish models for mild, moderate and severe acute organophosphorus poisoning by exposing zebrafish larvae to different concentrations of the prototypic organophosphorus compound chlorpyrifos-oxon...

A woman in her mid-50s contacted her social worker and expressed intent to commit suicide by ingesting prescription medications. On arrival of emergency responders, the patient was found unconscious with an empty bottle of amitriptyline. Time of ingestion was estimated using the social worker's contact with local authorities. The patient's presentation at the emergency department (ED) exemplified tricyclic antidepressant toxidrome with a poor prognosis, based on measurable criteria and physical findings. Respiratory and cardiovascular collapse was managed emergently...

OBJECTIVES: Drug misuse is a disturbing, common practice among youth. One in 4 American adolescents reports consuming prescription medications without a clinical indication. We sought to explore current trends of drug misuse in adolescents. METHODS: Using the 37 participating sites of the ToxIC (Toxicology Investigators Consortium) Case Registry, a cross-country surveillance tool, we conducted an observational cohort study of all adolescents (aged 13-18 years) who presented to emergency departments with drug misuse and required a bedside medical toxicology consultation between January 2010 and June 2013...
