    Description / Table of Contents: Sommario Gli Autori riportano l'inusuale semeiologia delle crisi in un bambino con una leucemia linfoblastica acuta. La sintomatologia convulsiva esordì acutamente con uno stato di male parziale somatomotorio con un rallentamento diffuso dell'EEG. Successivamente le crisi divennero di tipo mioclono-atonico (drop attacks), con comparsa di un focolaio EEG sulle aree centro-parietali paramediane di sinistra, attivato da stimoli propriocettivi. Nonostante la gravità del quadro clinico iniziale, le crisi hanno dimostrato successivamente un andamento favorevole, con scomparsa sotto trattamento con carbamazepina. Gli A. ipotizzano che la sindrome epilettica possa essere in rapporto ad una encefalopatia iatrogena, verosimilmente correlata con la somministrazione intratecale di metotrexate.
    Notes: Abstract We report the unusual seizures in a patient with acute lymphoblastic leukemia. The convulsive disorder began acutely as partial somatomotor status epilepticus and with diffuse EEG slowing. The seizures then became myoclonic-atonic (drop attacks) and an EEG focus appeared on the left paramedian centro-parietal areas, activated by proprioceptive stimuli. Despite the severity of the clinical picture at onset, the seizures showed a benign course, and disappeared on carbamazepine therapy. We think that this epileptic syndrome may have been caused by diffuse iatrogenic encephalopathy, probably related to intrathecal methotrexate therapy.

    Notes: Abstract The purpose of this study was to evaluate the frequency and characteristics of epilepsy associated with cerebral venous angiomas (VA). We examined epileptic patients in which magnetic resonance imaging (MRI) showed VA. The characteristics of epilepsy and its relationships to VA were studied. Out of 1020 epileptic patients submitted to MRI in a 10-year period, 4 presented with VA. All had partial seizures, most frequently complex partial, with secondary generalizations in 3. Drug resistance was observed in 2. One patient had a small area of cortical dysplasia near the VA; another had a cutaneous angioma. In 2 patients, there was no topographic concordance between the VA and the focus on electroencephalography. Our study reveals that VA are rarely found in epileptic patients, differently from other vascular malformations, in particular cavernomas. Topographic and/or etiological relationships between VA and epilepsy are still undefined.

    Description / Table of Contents: Sommario Viene descritto un caso di sindrome ipereosinofila idiopatica (HES). La malattia esordiva all'età di 31 anni con una sintomatologia simil-polineuropatica e disturbi dell'apparato gastrointestinale. Erano presenti ipereosinofilia e leucocitosi. Le indagini strumentali sull'apparato digestivo mostravano esofagite, ulcera peptica, segni di rettocolite cronica. Erano presenti cristalli di Charcot-Leyden nelle feci. All'EMG e agli studi di conduzione nervosa erano presenti alterazioni del sistema nervoso periferico. La biopsia muscolare era in accordo con i dati elettrofisiologici e mostrava anomalie di natura infiammatoria. L'istologia qualitativa ed il teasing delle fibre del nervo surale erano indicative di degenerazione assonale. Alcune sostanze proteiche derivate dalla degranulazione degli eosinofili possono essere responsabili dei disturbi osservati in vari sistemi ed organi.
    Notes: Abstract A case of idiopathic hypereosinophilic syndrome (HES) is reported. The disease started at the age of 31, with polyneuropathic-like symptoms and disorders of the gastrointestinal tract. Hypereosinophilia and leukocytosis were observed. Instrumental investigation of the digestive tract showed esophagitis, a peptic ulceration, signs of chronic rectocolitis. Charcot-Leyden crystals were present in feces. Peripheral nervous system changes were seen with EMG and nerve conduction studies. Muscle biopsy findings were in agreement with the electrophysiological data and showed inflammatory abnormalities. Qualitative histology and teased nerve fiber studies of sural nerve indicated axonal degeneration. Protein substances derived from eosinophils degranulation may account for the disturbances observed in various systems and organs.
