    Notes: Abstract Magnetic resonance imaging (MRI), single photon emission tomography (SPET), and positron emission tomography (PET) using [18F]fluorodeoxyglucose were used in combination with scalp and scalp-video EEGs in a group of 30 pediatric patients with drug resistant epilepsy (DRE) in order to identify patients who could benefit from neurosurgical approach. Seizures were classified according to the consensus criteria of The International League Against Epilepsy. In three patients infantile spasms (IS) were diagnosed; 13 subjects were affected by different types of generalized seizures, associated with complex partial seizures (CPS) in three. In the other 14 patients partial seizures, either simple (SPS) or complex, were present. A localized abnormality was demonstrated in one patient with IS and in three patients with generalized seizures. Of the group of 14 subjects with CPS, MRI and CT were normal in 7, but SPET or PET indicated focal hypoperfusion or hypometabolism concordant with the localization of the EEG abnormalities. In 5 of the other 7 patients anatomical and functional imaging and EEG findings were concordant for a localized abnormality. It can be concluded that functional imaging combined with scalp EEGs appears to be superior to the use of only CT and MRI for selecting children with epilepsy in whom a surgical approach can be considered, in particular when CPS resistant to therapy are present.

    Notes: Abstract We reviewed the clinical and EEG features of 30 Italian patients with childhood-onset neuronal ceroid lipofuscinosis (NCL). The outcome and the EEG pattern of the 4 infantile NCL cases were classic, although the age at onset of symptoms varied from 1.0 to 3.5 years. This latter finding is unusual and has not been reported for other Italian patients. Both typical and variant cases of late-infantile NCL (LINCL) were observed. This NCL type represents the most common form in our country, and was the largest group (18 cases) in our study. A particular pseudoperiodic EEG pattern was observed in 15 of the 18 patients with LINCL. This pattern may be useful in early diagnosis, especially if associated with the absence of sleep spindles. In the 8 cases with juvenile NCL, clinical and EEG findings were similar to those reported in the literature.
