Wound botulism.

M Cherington, S Ginsburg

    Archives of Surgery (Chicago, Ill. : 1960)
    |April 1, 1975
    PubMed
    Summary

    Wound botulism, previously considered rare, is increasingly diagnosed. Electrophysiologic studies are crucial for identifying this serious condition, even when traditional tests are inconclusive.

    Area of Science:

    • Neurology
    • Infectious Diseases
    • Toxicology

    Background:

    • Botulism associated with wounds is historically considered a rare clinical diagnosis.
    • Wound botulism presents a diagnostic challenge due to its infrequent occurrence and potential for non-specific initial symptoms.

    Purpose of the Study:

    • To highlight the diagnostic utility of electrophysiologic studies in suspected cases of wound botulism.
    • To underscore the importance of considering wound botulism in patients with relevant injury and neurological deficits.

    Main Methods:

    • Case presentation of a patient with a hand and wrist laceration and finger avulsion.
    • Clinical observation of neurological symptoms including diplopia, dizziness, slurred speech, weakness, and dysphagia.
    • Electrophysiologic assessment using repetitive nerve stimulation to detect neuromuscular blockade.

    Main Results:

    • Repetitive nerve stimulation revealed neuromuscular blockade consistent with botulism.
    • Initial bacteriologic and immunologic tests were negative.
    • The clinical course, characterized by fluctuating bulbar symptoms and eventual recovery, confirmed the diagnosis.

    Conclusions:

    • Wound botulism, though rare, should be considered in the differential diagnosis of neurological impairment following penetrating trauma.
    • Electrophysiologic testing, particularly repetitive nerve stimulation, is a valuable tool for diagnosing botulism when other methods fail.
    • Increased clinical awareness and utilization of electrophysiologic studies are leading to the identification of more wound botulism cases.
