Glue sniffer's neuropathy.

J Towfighi, N K Gonatas, D Pleasure

    Neurology
    |March 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Chronic inhalation of n-hexane (glue sniffing) caused progressive sensorimotor neuropathy in two patients. Nerve biopsies revealed axonal damage, suggesting a "dying-back" neuropathy mechanism.

    Area of Science:

    • Neuroscience
    • Toxicology
    • Pathology

    Background:

    • Investigating the neurological effects of chronic n-hexane exposure from glue sniffing.
    • Examining the pathological changes in peripheral nerves and muscles.

    Observation:

    • Two patients developed progressive sensorimotor neuropathy after prolonged n-hexane inhalation.
    • Sural nerve biopsies indicated axonal loss, widened nodes of Ranvier, and filament accumulation.
    • Muscle biopsies showed neurogenic atrophy, with nerve twigs and end-plates affected.

    Findings:

    • n-Hexane exposure leads to significant peripheral nerve damage, including axonal degeneration.
    • Pathological findings in n-hexane neuropathy resemble those seen in acrylamide neuropathy.
    • The observed nerve damage pattern is consistent with a "dying-back" neuropathy.

    Implications:

    • n-Hexane is a neurotoxin that can cause severe, progressive peripheral nerve damage.
    • Understanding the mechanism of n-hexane neuropathy is crucial for diagnosis and treatment.
    • This study highlights the risks associated with chronic solvent abuse.
