  • Chronic occupational metallic mercurialism
    Faculdade de Saúde Pública da Universidade de São Paulo, 2003
    Co-Authors: Faria, Marcília De Araújo Medrado
    Abstract:

    Revisão que analisa os conhecimento atuais das manifestações do mercuralismo crônico ocupacional. Avaliaram-se os principais estudos e revisões científicas concernentes às formas clínicas e fisiopatogenia desta intoxicação. Foram pesquisadas, entre outras fontes, as bases de dados Medline e Lilacs. O eretismo ou a síndrome neuropsíquica caracterizada por sintomas de irritabilidade, ansiedade, mudanças de comportamento, apatia, perda da auto-estima e de memória, depressão, insônia, delírio, cefaléia, dores musculares e tremores é observada após a exposição ao mercúrio metálico. Manifestações de hipertensão arterial, renais, imunológicas e alérgicas são freqüentes. A falta de medidas preventivas aumenta o risco da doença em indústrias, no garimpo e consultórios odontológicos. A legislação brasileira assinala 16 manifestações clínicas determinadas pela intoxicação, todavia ocorre subdiagnóstico. O diagnóstico clínico é importante e as novas tecnologias médicas podem detectar alterações do sistema nervoso central, renal e imunológico, proporcionando avanços no conhecimento neuro-imuno-toxicológico e nas medidas de prevenção do mercuralismo.This is a review on current knowledge of chronic occupational mercurialism syndrome. Major scientific studies and reviews on clinical manifestation and physiopathology of mercury poisoning were evaluated. The search was complemented using Medline and Lilacs data. Erethism or neuropsychological syndrome, characterized by irritability, personality change, loss of self-confidence, depression, delirium, insomnia, apathy, loss of memory, headaches, general pain, and tremors, is seen after exposure to metallic mercury. Hypertension, renal disturbances, allergies and immunological conditions are also common. Mercury is found in many different work processes: industries, gold mining, and dentistry. As prevention measures are not often adopted there is an increasing risk of mercury poisoning. The disease has been under diagnosed even though 16 clinical forms of mercury poisoning are described by Brazilian regulations. Clinical diagnosis is important, especially because abnormalities in the central nervous, renal and immunological systems can be detected using current medical technology, helping to develop the knowledge and control measures for mercurialism

  • the toxicology of mercury
    Critical Reviews in Clinical Laboratory Sciences, 1997
    Co-Authors: Thomas W Clarkson
    Abstract:

    AbstractThe major physical forms of mercury to which humans are exposed are mercury vapor, Hg0, and methylmercury compounds, CH3HgX. Mercury vapor emitted from both natural and anthropogenic sources is globally distributed in the atmosphere. It is returned as a water-soluble form in precipitation and finds its way into bodies of fresh and ocean water. Land run-off also accounts for further input into lakes and oceans. Inorganic mercury, present in water sediments, is subject to bacterial conversion to methylmercury compounds that are bioaccumulated in the aquatic food chain to reach the highest concentration in predatory fish. Human exposure to mercury vapor is from dental amalgam and industries using mercury. Methylmercury compounds are found exclusively in seafood and freshwater fish. The health effects of mercury vapor have been known since ancient times. Severe exposure results in a triad of symptoms, Erethism, tremor, and gingivitis. Today, we are concerned with more subtle effects such as preclinica...

  • HYPERTENSIVE ENCEPHALOPATHY INDUCED BY MERCURY POISONING; A REPORT OF 3 CASES (IN AN IRANIAN FAMILY)
    2007
    Co-Authors: M. Sharifian, M. Noorisafa, M. Kiahosseini
    Abstract:

    Mercury poisoning is one of the important recent causes of mortality and mortality in children worldwide, particularly in industrial environments; mercury is a poisonous metal, especially harmful to the nervous and immune systems and the kidneys and can even be fatal. Elemental mercury is present in thermometers, barometer batteries, sphygmomanometers and latex paints. Inorganic mercury salts are found in antiseptics, pesticides, pigments and explosives and are used as preservatives in medicine. Mercury was once used to stop fever, and this worked because the immune system was so weakened that it could no longer sustain the attack for which the fever was created. Some medical drugs still contain mercury chloride and mercurous chloride and certain forms of mercury are still used in some laxatives. Mercury toxicity of the nervous system causes anorexia, ataxia, lack of ability to coordinate voluntary muscle movements, dementia, depression, dizziness, emotional instability, Erethism (abnormal irritability in response to stimulation), incoordination, insomnia, irritability, loss of ability to speak, memory impairment

  • HYPERTENSIVE ENCEPHALOPATHY INDUCED BY MERCURY POISONING; A REPORT OF 3 CASES (IN AN IRANIAN FAMILY)

    Abstract:

    Objective Mercury poisoning is one of the important recent causes of mortality and mortality in children worldwide, particularly in industrial environments; mercury is a poisonous metal, especially harmful to the nervous and immune systems and the kidneys and can even be fatal. Elemental mercury is present in thermometers, barometer batteries, sphygmomanometers and latex paints. Inorganic mercury salts are found in antiseptics, pesticides, pigments and explosives and are used as preservatives in medicine. Mercury was once used to stop fever, and this worked because the immune system was so weakened that it could no longer sustain the attack for which the fever was created. Some medical drugs still contain mercury chloride and mercurous chloride and certain forms of mercury are still used in some laxatives. Mercury toxicity of the nervous system causes anorexia, ataxia, lack of ability to coordinate voluntary muscle movements, dementia, depression, dizziness, emotional instability, Erethism (abnormal irritability in response to stimulation), incoordination, insomnia, irritability, loss of ability to speak, memory impairment, numbness, saresthesias (sensation of prickling, tingling or creeping on the skin), psychosis, tremors, drowsiness, fatigue and weakness. Other organ damages include kidney failure, headaches, hearing impairment, visual impairment, hypertension, dermatitis, digestive tract problems, colitis, diarrhea, stomatitis and excessive salivation, loss of teeth, metallic taste, chromosomal damage, birth defects and ensuing organ failure. Chronic mercury poisoning can cause Acrodynia (Pink disease). Mercury poisoning is a rare cause of hypertension in children. Herein we report 3 cases, the first a child with hypertensive encephalopathy due to severe mercury poisoning and his two siblings with moderate symptoms. Case report A 10 year old boy was admitted in psychiatric ward of Imam Hossein Hospital with behavioral disorder, irritability, mood change and convulsion. Because of his blood pressure which was 160/120 he was referred and admitted to the Pediatric Nephrology department. On arrival, for his hypotonia and the pink  discoloration of his fingers a diagnosis of Acrodynia (Pink disease) was considered; his history showed that he has played with a ball of mercury, taken from a laboratory. He and his 2 siblings received British Anti Lewisite(BAL) and D-penicillamin; at follow-up all symptoms had gradually disappeared and they are well now.
