✦ Synopsis
We undertook a biopsy of a terminal branch of the musculocutaneous nerve in a man with severe Guillain-Barre syndrome and very small distally evoked action potentials. The biopsy showed pronounced subperineurial edema, macrophage infiltration, and many axons that had been completely demyelinated, some associated with intratubal macrophages. The biopsy unequivocally identified the pathological process as primary demyelination, not axonal degeneration, and was more informative than previous reports of sural nerve biopsies in patients with Guillain-Barre syndrome.

## Abstract Adynamic ileus occurred in 17 of 114 patients (15%) with severe Guillain–Barré syndrome (GBS). Cardiovascular dysautonomia coincided with ileus in only five patients. In four patients, mechanical ventilation and immobilization could be implicated; and in eight patients, preexisting cond
Among eight sural nerve biopsies from patients with the Guillain-Bar& syndrome (GBS), demyelination was ob- served in five and endoneural mononuclear cell infiltrates in three. Receptors for the activated third component of complement (C3b) were detected within the nerve fascicles. The receptor acti
