Five right-handed children with Landau-Kleffner syndrome (LKS) who had disease onset between the ages of 3 and 9 years were studied with EEG and single-photon emission computed tomography (SPECT) before and, in four cases, after 6 months of corticosteroid treatment. EEG findings included both focal and generalized spikes as well as spike-wave discharges(More)
This paper presents an approach to perform neutral facial image recognition through facial expression image. The differential of this work is the previous images processing. First, the dimension is reduced. Next, the image is sliced into gray levels, from the most significant bits to the less significant bits. Finally, eight parallel hopfield neural(More)
We conducted an open, add-on study with topiramate (TPM) as adjunctive therapy in Lennox-Gastaut syndrome (LGS), to assess the long-term efficacy and safety and to evaluate quality of life (QL) measurements in the chronic use of TPM. We studied 19 patients (11 male; age ranging from 4 to 14 years) with uncontrolled seizures receiving 2-3 anti-epileptic(More)
Germination of coffee (Coffea arabica L.) seed is slow and uneven. Its germination is the net result of events that occur simultaneously in the embryo and endosperm and which are controlled by abscisic acid (ABA). The aim of the study was to monitor the expression of genes related to the cell cycle and to cell wall modifications, including an actin (ACT), a(More)
This paper presents an approach to perform neutral facial image recognition through expression facial image using Hopfield neural networks. The dimension of neutral facial image is reduced and the image is sliced into gray levels, from the most significant bits to the less significant bits. The same process is applied to the expression facial image. The(More)
Children, 47, with various types of severe drug-resistant epilepsy were entered into a prospective, add-on, open trial with vigabatrin. Patients with West syndrome and idiopathic generalized epilepsies were excluded. Seven children had the drug withdrawn, five because of increase in seizure frequency and two because of adverse effects. Drug efficacy,(More)
We present our results of intermittent prophylaxis with oral diazepam in febrile seizures. We treated 82 patients aged between 3 months and 5 years. They have had simple or complex febrile seizures. Recurrence occurred in 22 patients (26%), none had a long-lasting febrile convulsion. Transient side effects occurred in 21.95% of the cases. We conclude that(More)
Intermittent prophylaxis with oral diazepam is presented as an optional treatment for febrile seizures. This proposition is justified by the severe side effects of the currently used chronic anticonvulsant drug therapy in febrile seizures (phenobarbital and valproate). Nineteen patients aged between 3 months and 5 years were treated. They had either simple(More)
