is 3% and the chance of relapse has been reported as 7% in children. Cause: It can follow an upper respiratory infection or gastrointestinal viral infection. A specific type of GI infection
produced by the bacteris campylobacter jejuni has been particularly associated with GBS. It is considered an
autoimmune disease. Also called Acute Inflammatory Peripheral

sundials on the top of the hill, and the 'borogroves' were afraid that their nests would be undermined. The hill was probably full of the nests of 'raths', which ran
out, squeaking with fear, on hearing the 'toves' scratching outside. This is an obscure, but yet deeply-affecting, relic of ancient Poetry." (
