Unfortunately the page on Guillain-Barré has been unavailable for a while because our web server does not speak French. As the file name for the page used the correct spelling (Guillain-Barré), the anglophile server refused to recognise it and was displaying an error message instead. The page is now available again, however (apologies to all the Francophiles out there), at the expense of dropping the accent from the final e in Barré. Nos excuses, but it was easier than trying to teach the web server French.
