[Delayed-type subacute measles encephalitis].

Introduction: We analyze the clinical, neurological, EEG, neuroradiological features and evolution of two patients with subacute measles encephalitis.

Case Reports: The patients, aged five years and eleven months respectively showed an acute, progressive neurological compromise and deterioration of consciousness, epilepsia partialis continua and progressive damage on neuroimaging, with a history of measles in the first case and exposure to the virus in the second. The first patient had Hodgkin's disease and the other had a familial C4 deficit disorder.

[Reflex myoclonic epilepsy in infancy: a new reflex epilepsy syndrome or a variant of benign myoclonic epilepsy in infancy].

Case Reports: We report a clinical and EEG study of 8 children with reflex myoclonic epilepsy of infancy to further confirm the existence of this syndrome first described by Ricci et al in 1995.

Results: Between February 1990 to July 2002, we identified 64 epileptic patients with myoclonic seizures with an onset in the first six years of life. Eight (12.

[Acquired epileptic aphasia].

Objective: To evaluate clinical and EEG features, as well as treatment and progression in fifteen patients with a diagnosis of acquired epileptic aphasia.

Patients And Methods: The population comprised nine male and six female patients, whose mean age was 14.5 (r = 8.

[Cerebral magnetic resonance in the study of West syndrome].

Introduction And Objective: West's syndrome (WS) is an epileptic encephalopathy of the first year of life, associated with different aetiologies. MRI of the brain allows precise determination of the type and extent of the lesions. The aetiology must be recognised in order to establish the prognosis and a suitable therapeutic approach.

[Benign neonatal sleep myoclonus].

Objective: To evaluate the clinical, electro-encephalographic and evolutionary characteristics of a series of patients diagnosed as having benign neonatal sleep myoclonus (BNSM).

Material And Methods: The clinical histories of 21 patients with BNSM were analyzed. Criteria for inclusion in the study were: neonates who had had more than one episode of myoclonia during sleep and in whom neurological examination and psychomotor development were normal.

[Benign paroxysmal tonic upward gaze syndrome].

Introduction: The benign paroxysmal tonic upward gaze syndrome (BPTUG) is a rare condition. We present two new cases analyzing the clinical, genetic, evolution and therapeutic aspects.

Clinical Cases: Case 1.
