    Area of Science:

    • Neurology
    • Toxicology
    • Occupational Medicine

    Background:

    • Chronic manganese poisoning is a serious occupational hazard.
    • Exposure can occur through industrial fumes (e.g., manganese steel) or dusts (e.g., manganese dioxide in ceramics).
    • Previous reports of manganese intoxication in California were lacking.

    Purpose of the Study:

    • To report two cases of chronic manganese poisoning in California.
    • To highlight the diagnostic challenges and clinical manifestations.
    • To emphasize the importance of considering manganese intoxication in differential diagnoses.

    Main Methods:

    • Case report of two individuals with suspected chronic manganese poisoning.
    • Clinical observation and symptom documentation.

    Related Experiment Videos

  • Review of exposure history and diagnostic workup.

    • Main Results:

    • Case 1: Exposure to manganese fumes, presenting with chronic depressive psychosis and extrapyramidal symptoms.
    • Case 2: Exposure to manganese dioxide dust, presenting with transient acute brain syndrome and extrapyramidal symptoms.
    • Both cases presented diagnostic challenges, underscoring the need for awareness.

    Conclusions:

    • Chronic manganese poisoning can manifest with diverse neurological and psychiatric symptoms.
    • Increased industrial use of manganese necessitates its consideration in diagnosing related illnesses.
    • Levodopa has emerged as a significant therapeutic advancement for manganese poisoning victims.
