[Partial benign crises in adolescence].

The aim of this paper is to present the case of teenage patient with partial seizures fulfilling the criteria of benign partial seizures of adolescence. A 16-year-old male patient had two seizures with a sensory-motor "march" that evolved into a secondarily generalized tonic-clonic seizure on the same day. Several weeks before this event he had had several simple partial sensory seizures. The patient had no previous history of seizures and there was no family history of epilepsy. The neurological examination, EEG and magnetic resonance imaging were normal. The patient was treated with antiepileptic monotherapy during two years. The treatment was gradually tapered and withdrawn over the following six months. He has had no recurrences during the five years of follow-up. The early diagnosis of this entity has the significant prognostic and therapeutic repercussions.

[Validation of transcranial Doppler in Mataro, Barcelona].

INTRODUCTION: Transcranial Doppler (TCD) is a new technique which is becoming increasingly used in neurology and is highly dependent on the user. OBJECTIVE: To evaluate the reliability of TCD in our hospital. PATIENTS AND METHODS: During a five month period, all patients who had a cerebral angiogram done, also had DTC within 24 hours. The TCD was reported on before the result of the angiogram was known. Subsequent analysis of the comparison of the results was done by a person who had not done the initial investigations. RESULTS: 49 persons were included in the study. The average time between the two investigations was 12.5 hours. In 5 patients the TCD was inconclusive due to a poor window. In 21 patients both tests were normal. Of the 14 patients in whom there were pathological findings on angiography, correct diagnosis was made on TCD in 12 cases, including those with stenosis of the anterior circulation. The two false negative findings of intracranial stenosis were in a vertebral artery and a posterior cerebral artery. The remaining seven cases were of patients in whom only one investigation showed signs of distal vasculopathy. CONCLUSION: The index of false positives of DTC showing intracranial stenosis was 0. All intracranial stenoses of the anterior circulation were correctly diagnosed.

[Clinical utility of outpatient videoelectroencephalogram monitoring].

OBJECTIVE: To analyze the utility of outpatient videoelectroencephalogram (VEEG) in a general neurology department to detect an ictal event. PATIENTS AND METHODS: One hundred and five patients with ictal phenomenology of unknown etiology, suspicion of pseudoseizures, refractory epilepsy with very frequent seizures, underwent outpatient VEEG monitoring from 30 minutes to five hours of duration, between June 1, 1999 and June 30, 2003. Patient medication was not modified to perform the recording. RESULTS: Among the 105 outpatient VEEG monitoring, 33 clinical pathologic events were identified; these comprised 14 epileptic seizures, 12 pseudoseizures, four syncopes, and three non epileptic abnormal movements. Outpatient VEEG monitoring duration was as follows: 30 minutes in 12 patients, between 30 minutes and two hours in another 12, and more than two hours in 9. In 19 patients, the VEEG recording allowed a definitive diagnosis; in one case, it changed the epileptic seizure type, and in 11 patients, it helped to better characterize the epileptic seizure type. CONCLUSION: Although the percentage of pathologic events during an outpatient VEEG monitoring of 30 minutes to five hours of duration is low, its clinical repercussion is very important and the added cost is low.
