Organophosphate-induced delayed neuropathy (OPIDN), also called organophosphate-induced delayed polyneuropathy (OPIDP), is a neuropathy caused by killing of neurons in the central nervous system, especially in the spinal cord, as a result of acute or chronic organophosphate poisoning.
OPs are one of the most common causes of poisoning worldwide. [2] There are nearly 3 million poisonings per year resulting in two hundred thousand deaths. [2] [3] Around 15% of people who are poisoned die as a result. [2] Organophosphate poisoning has been reported at least since 1962. [7]
Malathion, one of the first organophosphate insecticides. It remains important as a Vector control agent. Organophosphates are best known for their use as pesticides. The vast majority are insecticides and are used either to protect crops, or as vector control agents to reduce the transmission of diseases spread by insects, such as mosquitoes ...
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
Common mnemonics for the symptomatology of organophosphate poisoning, including sarin, are the "killer Bs" of bronchorrhea and bronchospasm because they are the leading cause of death, [8] and SLUDGE – salivation, lacrimation, urination, defecation, gastrointestinal distress, and emesis (vomiting). Death may follow in one to ten minutes after ...
If one is regularly using carbamate and organophosphate pesticides, it is important to obtain a baseline cholinesterase test. [25] [26] Cholinesterase is an important enzyme of the nervous system, and these chemical groups kill pests and potentially injure or kill humans by inhibiting cholinesterase. If one has had a baseline test and later ...
One of the most notable uses of endogenous glutamate is its functionality as an excitatory neurotransmitter. [53] When concentrated, however, glutamate becomes toxic to surrounding neurons. This toxicity can be both a result of direct lethality of glutamate on neurons and a result of induced calcium flux into neurons leading to swelling and ...
Oligonucleotide phosphorothioates (OPS) are modified oligonucleotides where one of the oxygen atoms in the phosphate moiety is replaced by sulfur. These compounds are the basis of antisense therapy, e.g., the drugs fomivirsen (Vitravene), oblimersen, alicaforsen, and mipomersen (Kynamro). [2] Further examples of these include: Diazinon ...
