Clin Toxicol 2015; online early: doi: 10.3109/15563650.2015.1022896: Introduction Tolperisone is a centrally acting muscle relaxant that acts by blocking voltage-gated sodium and calcium channels. There is a lack of information on the clinical features of tolperisone poisoning in the literature. The aim of this study was to investigate the demographics, circumstances and clinical features of acute overdoses with tolperisone. Methods An observational study of acute overdoses of tolperisone, either alone or in combination with one non-steroidal anti-inflammatory drug in a dose range not expected to cause central nervous system effects, in adults and children (< 16 years), reported to our poison centre between 1995 and 2013. Current Awareness in Clinical Toxicology is produced monthly for the American Academy of Clinical Toxicology by the Birmingham Unit of the UK National Poisons Information Service, with contributions from the Cardiff, Edinburgh, and Newcastle Units. The NPIS is commissioned by Public Health England Results 75 cases were included: 51 females (68%) and 24 males (32%); 45 adults (60%) and 30 children (40%). Six adults (13%) and 17 children (57%) remained asymptomatic, and mild symptoms were seen in 25 adults (56%) and 10 children (33%). -

Methanol Interim AEGL Document
INTERIM 1: 1/2003 INTERIM 2: 2/2005 INTERIM ACUTE EXPOSURE GUIDELINE LEVELS (AEGLs) METHANOL (CAS Reg. No. 67-56-1) For NAS/COT Subcommittee for AEGLs February 2005 METHANOL Interim 2: 2/2005 PREFACE Under the authority of the Federal Advisory Committee Act (FACA) P. L. 92-463 of 1972, the National Advisory Committee for Acute Exposure Guideline Levels for Hazardous Substances (NAC/AEGL Committee) has been established to identify, review and interpret relevant toxicologic and other scientific data and develop AEGLs for high priority, acutely toxic chemicals. AEGLs represent threshold exposure limits for the general public and are applicable to emergency exposure periods ranging from 10 minutes to 8 hours. AEGL-2 and AEGL-3 levels, and AEGL-1 levels as appropriate, will be developed for each of five exposure periods (10 and 30 minutes, 1 hour, 4 hours, and 8 hours) and will be distinguished by varying degrees of severity of toxic effects. It is believed that the recommended exposure levels are applicable to the general population including infants and children, and other individuals who may be sensitive or susceptible. The three AEGLs have been defined as follows: AEGL-1 is the airborne concentration (expressed as ppm or mg/m;) of a substance above which it is predicted that the general population, including susceptible individuals, could experience notable discomfort, irritation, or certain asymptomatic, non-sensory effects. However, the effects are not disabling and are transient and reversible upon cessation of exposure. AEGL-2 is the airborne concentration (expressed as ppm or mg/m;) of a substance above which it is predicted that the general population, including susceptible individuals, could experience irreversible or other serious, long-lasting adverse health effects, or an impaired ability to escape. -
Methanol: Toxicological Overview
Methanol Toxicological Overview Key Points Kinetics and metabolism readily absorbed by all routes and distributed in the body water undergoes extensive metabolism, but small quantities are excreted unchanged by the lungs and in the urine Health effects of acute exposure methanol is toxic following ingestion, inhalation or dermal exposure exposure may initially result in CNS depression, followed by an asymptomatic latent period metabolic acidosis and ocular toxicity, which may result in blindness, are subsequent manifestations of toxicity coma and death may occur following substantial exposures long-term effects may include blindness and, following more substantial exposures, permanent damage to the CNS Health effects of chronic exposure long-term inhalation exposure to methanol has resulted in headaches and eye irritation in workers methanol is considered not to be a mutagen or carcinogen in humans methanol is considered not to be a reproductive toxicant in humans PHE publications gateway number: 2014790 Published: August 2015 Compendium of Chemical Hazards: Methanol Summary of Health Effects Methanol may be acutely toxic following inhalation, oral or dermal exposure. Acute methanol toxicity often follows a characteristic series of features; initially central nervous system (CNS) depression and gastrointestinal tract (GI) irritation may be observed. This is typically followed by a latent period of varying duration from 12–24 hours and occasionally up to 48 hours. Subsequently, a severe metabolic acidosis develops with nausea, vomiting and headache. Ocular toxicity ranges from photophobia and misty or blurred vision to markedly reduced visual acuity and complete blindness following high levels of exposure. Ingestion of as little as 4–10 mL of methanol in adults may cause permanent damage. -

Question of the Day Archives: Monday, December 5, 2016 Question: Calcium Oxalate Is a Widespread Toxin Found in Many Species of Plants
Question Of the Day Archives: Monday, December 5, 2016 Question: Calcium oxalate is a widespread toxin found in many species of plants. What is the needle shaped crystal containing calcium oxalate called and what is the compilation of these structures known as? Answer: The needle shaped plant-based crystals containing calcium oxalate are known as raphides. A compilation of raphides forms the structure known as an idioblast. (Lim CS et al. Atlas of select poisonous plants and mushrooms. 2016 Disease-a-Month 62(3):37-66) Friday, December 2, 2016 Question: Which oral chelating agent has been reported to cause transient increases in plasma ALT activity in some patients as well as rare instances of mucocutaneous skin reactions? Answer: Orally administered dimercaptosuccinic acid (DMSA) has been reported to cause transient increases in ALT activity as well as rare instances of mucocutaneous skin reactions. (Bradberry S et al. Use of oral dimercaptosuccinic acid (succimer) in adult patients with inorganic lead poisoning. 2009 Q J Med 102:721-732) Thursday, December 1, 2016 Question: What is Clioquinol and why was it withdrawn from the market during the 1970s? Answer: According to the cited reference, “Between the 1950s and 1970s Clioquinol was used to treat and prevent intestinal parasitic disease [intestinal amebiasis].” “In the early 1970s Clioquinol was withdrawn from the market as an oral agent due to an association with sub-acute myelo-optic neuropathy (SMON) in Japanese patients. SMON is a syndrome that involves sensory and motor disturbances in the lower limbs as well as visual changes that are due to symmetrical demyelination of the lateral and posterior funiculi of the spinal cord, optic nerve, and peripheral nerves. -

Spread of Alimentary-Toxic Paroxysmal Myoglobinuria-Haff Disease (Literature Review)
E3S Web of Conferences 254, 09002 (2021) https://doi.org/10.1051/e3sconf/202125409002 FARBA 2021 Spread of alimentary-toxic paroxysmal myoglobinuria-haff disease (literature review) L.A. Glazunova*, A.R. Musina, A.A. Yurchenko, Y.V. Glazunov, and E.M. Gagarin Federal State Budgetary Educational Institution of Higher Education Northern Trans-Ural State Agricultural University, Tyumen, Russia Abstract. In 1924, Haff disease was first detected in East Prussia. Till now, cases of Haff disease have been recorded in Sweden, Russia, the United States, China, Brazil, Japan, and China among people and animals. During the last 40 years, there has been a significant expansion in the geographical range of Haff disease. From 1924 to 2019, 31 outbreaks were recorded in various parts of the world. The total number of victims was about 3,000 people. In Russia, the last cases of human disease were registered in 2019- 2020. In fact, the source of the toxin is fish (crucian carp, carp, pike, burbot, walleye, perch, ruff, ide, yellowtail, black sea bass, eel, silver dollar, brown paku, red paku, cowfish, etc.) or crayfish. Today, the problem of the disease etiology has not been solved; the toxin with the corresponding features has not been isolated, and as a result, causal and pathogenetic treatment of alimentary-toxic paroxysmal myoglobinuria has not been developed. Over this period, several hypotheses were made that are leading in the study of the etiology of the occurrence of Haff disease (thiaminase theory, tannic, arachidonic). This disease-causing substance is known to be heat-resistant and break down the metabolism of skeletal muscles, resulting in the release of myoglobin, which disorders kidney function. -
