Public health department response to mercury poisoning: the importance of biomarkers and risks and benefits analysis for chelation therapy

Clinical management of chronic mercury intoxication secondary to skin lightening products: A proposed algorithm

Mercury is a toxic substance that is commonly used in skin lightening products. Various effects on humans have been observed, which affect both users and non-users. Many studies reported delayed diagnosis and treatment, even after weeks of hospitalization. The possible reasons are non-specific clinical manifestation and lack of awareness and knowledge regarding chronic mercury intoxication secondary to skin lightening products. A thorough history of mercury exposure is crucial. Physical assessment and relevant supporting tests are indicated to establish a diagnosis. Blood and urine mercury levels are an essential examination for diagnosis and monitoring of the progress and response to treatment. The primary treatment is the discontinuation of the skin lightening products. Chelation therapy is not mandatory and is usually indicated for symptomatic patients. The prognosis depends on the duration of the product use, concentration of mercury in the skin product, and the severity of clinical presentation.

Medical toxicology case presentations: to chelate or not to chelate, is that the question?

Four case studies described in this article were presented to a panel of physicians participating in the ACMT "Use and Misuse of Metal Chelation Therapy" Symposium in February 2012. The individuals who participated in the panel are listed in the appendix. These cases highlight some of the practical questions facing medical providers when issues of metal toxicity and its treatment arise. Medical toxicologists are valuable resources for information, public debate, consultation, and treatment of patients with concerns about heavy metal exposure.
