Name of journal: Health science reportsAbstract: Background and aims: Elemental mercury toxicity is a rare condition which can be difficult to diagnose due to its nonspecific signs and symptoms. The purpose of this investigation is to describe the presenting characteristics and treatment of adult and pediatric patients with elemental mercury poisoning.Conclusion: The evaluation and treatment of patients with suspected elemental mercury poisoning frequently require a multidisciplinary approach including medical toxicologists and public health officials. A heightened awareness of the clinical presentations of this condition, as well as early identification and removal of patients from the source of exposure and consideration of chelation therapy, can result in accelerated patient recovery. Copyright (c) 2021 The Authors. Health Science Reports published by Wiley Periodicals LLC.Methods: A retrospective review was performed in six patients with elemental mercury exposure or intoxication who were treated in an outpatient medical toxicology clinic. Clinical signs and symptoms, laboratory assessments, and public health responses were reviewed.Results: Headache, anorexia, rash, and personality changes were commonly reported symptoms in pediatric patients; the adult patients were asymptomatic or reported signs and symptoms included myalgias, tremors, and hypertension. Delays in diagnosis were common. Symptomatic patients had 24-hour urine mercury concentrations greater than 20 mcg/L. Treatment, including removal from the exposure source as well as chelation with dimercaptosuccinic acid, resulted in resolution of signs and symptoms within 6 months of diagnosis.All authors: Farrell J Jr, Johnson-Arbor K, Tefera EFiscal year: FY2021Digital Object Identifier: Date added to catalog: 2021-07-19
