Neurological involvement in children with E. coli O104:H4-induced hemolytic uremic syndrome.

Background: The aim of this study was to analyze the neurological involvement and outcome in pediatric patients with hemolytic uremic syndrome (HUS) during the 2011 epidemic caused by Escherichia coli O104:H4.

Methods: Clinical data and data from magnetic resonance imaging (MRI) scans and electroencephalography (EEG) during the acute phase of the disease and during follow-up at 3 and 6 months were analyzed in 50 patients. Twenty-five of these patients underwent neuropsychological testing (WISC IV) during follow-up.

On the existence of radially symmetric blow-up solutions for the Keller-Segel model.

We investigate the existence of radially symmetric solutions of the Keller-Segel model [abstract see text] which blow up in finite or infinite time, i.e.[abstract see text] for T(max) < or = infinity, under a larger class of initial data than in [10] and [11].
