Neuropsychiatric manifestations following acute organophosphate poisoning

open access: yesMedical Journal of Dr. D.Y. Patil University, 2016
Acute muscarinic and nicotinic side effects of organophosphate (OP) poisoning are well known and easily recognized, but neuropsychiatric changes are rarely reported. We are reporting a case of a 22-year-old male who developed psychotic features and motor

Temporal Trends in Exposure to Organophosphate Flame Retardants in the United States

open access: yesEnvironmental Science and Technology Letters, 2017
During the past decade, use of organophosphate compounds as flame retardants and plasticizers has increased. Numerous studies investigating biomarkers (i.e., urinary metabolites) demonstrate ubiquitous human exposure and suggest that human exposure may ...
