[Acute polyradiculoneuritis in children. Clinical and developmental aspects. Prognostic factors apropos of 100 cases].

The main clinical features of acute infectious polyneuritis are described from a study of 100 cases. The distinction between Guillain-Barré syndrome and the atypical forms of the condition is arbitrary. In particular, the atypical features (pleocytosis, normal C.S.F. protein, relapses) had no influence on the final prognosis. In contrast, the severity of the distal neurological deficit, the duration of the acute illness, a late dissociation between the cells and proteins C.S.F., the age and sex were all statistically significant prognostic factors.
