Impaired sleep-related consolidation of declarative memories in idiopathic focal epilepsies of childhood.

Objective: Declarative memory is consolidated during sleep in healthy children. We tested the hypothesis that consolidation processes are impaired in idiopathic focal epilepsies (IFE) of childhood in association with frequent interictal epileptiform discharges (IEDs) during sleep.

Methods: A verbal (word-pair association) and a nonverbal (2D object location) declarative memory task were administrated to 15 children with IFEs and 8 control children 6-12 years of age.

[Familial epithelioma of Ferguson-Smith about two familial cases].

Two cases of multiple self-healing epithelioma (Ferguson-Smith) are reported in a French family. This dermatosis has been present since the age of 30 in both father and son. The father aged 66 years, farmer, had suffered since 1939 from recurrent spontaneously healing tumors of the face and neck, with deeply pitted scars on the face.
