    history of slurred speech, double vision, and
    dysphagia, a 24-year-old
    woman becomes quadriplegic and requires intubation and
    mechanical
    ventilation. Her medical history is unremarkable.

    and diarrhea since the picnic. Her temperature is 37

    mucous membranes, large unreactive pupils,
    ophthalmoplegia, and
    profound facial weakness. There is areflexia,
    quadriplegia, and no movement
    of the palate and tongue. Sensation is normal.
