24-year preoperative evolution of a temporal astrocytoma.

We report the case of a patient suffering since 5 months of age from complex focal seizures that could not be controlled with medication and who developed severe psychomotor retardation. When she was 25 years old she was operated on for a left temporal lobe type II astrocytoma which had been detected but misinterpreted on CT scans performed at 12 and 18 years of age. After surgical and radiotherapy treatment the patient was seizure-free for 9 months, but then epilepsy reappeared and the patient died 19 months after surgery. Postsurgical malignant transformation is suspected but not histologically confirmed.

Epileptic akinetic mutism: following temporal lobectomy for Rasmussen's syndrome.

A girl aged 9 years with Rasmussen's encephalitis previously treated by left temporal lobectomy suddenly developed prolonged attacks of extremely rapid respirations associated with poverty of body movements and greatly reduced facial movements with loss of speech. Her comprehension appeared intact and she responded to certain requests. Her eye gaze behaviour suggested a high degree of vigilance. The attacks would last from minutes to hours and were repeated up to a dozen times daily. In the context of the stress generated by the illness and other family problems the attacks had been mistaken for an hysterical elaboration. Their ictal nature was confirmed by EEG/video monitoring. Possible links with other developmental language disorders associated with epilepsy are discussed, including a model of autism.

Crossed aphasia. Report of a rare case in a glioblastoma patient.

A rare case of a right-handed (on the Edinburgh Inventory) woman who developed aphasia at the clinical onset of a right hemisphere glioblastoma (GBM) is reported. She showed Wernicke aphasia and left spatial neglect. The integrity of the left hemisphere was assessed by Magnetic Resonance Imaging (MRI). A few aspects of hemispheric specialization for language, praxias and spatial abilities are briefly discussed.

Vascular abnormalities in surgical specimens obtained from the resected focus of intractable epilepsy.

The histopathological features, particularly hypervascularity, were examined in specimens resected from 21 patients, 15 with intractable epilepsy accompanying cortical dysplasia or dysembryoplastic neuroepithelial tumor (DNT), and 6 with benign brain tumors, such as ganglioglioma and low-grade glioma. Hypervascularity was found in resected specimens from 15 of the 21 patients (71.4%) and in 10 of the 12 patients (83.3%) who had double pathology. Counting of numbers of vessels by CD31 immunohistochemistry revealed that hypervascularity was prominent, especially in cases of vascular malformation or cortical dysplasia. However, almost all cases were negative for vascular endothelial growth factor (VEGF) staining, except for some cases of benign brain tumors. Moreover, all cases showed low or no proliferative potential in MIB-1 immunohistochemistry. These results suggest that the etiology of hypervascularity in the dysplastic lesions is one of a variety of cerebral malformations, as is the case with abnormal maturation and differentiation in neuroglial elements.

[Coincidence of epilepsy and Asperger syndrome. Case report and review].

Asperger syndrome is an autistic disorder and was first described by Hans Asperger in 1944 without further acceptance in the literature over almost four decades. Following several publications in the 1980s, for the disorder became more widely known and was first introduced into ICD-10 and DSM-IV as a new diagnosis in 1988 and 1994, respectively. The etiology is unknown. We present a female patient with typical features of Asperger syndrome, suffering also from epilepsy and internal medical disorders. The associated diseases, diagnostic criteria and possible therapeutic options are discussed.

[Tiagabine and non-convulsive status epilepticus].

A case report is given to draw attention to the risk of the occurrence of nonconvulsive status epilepticus (NCSE) under the anticonvulsant tiagabine in higher doses and doses increases. The patient who had no previous history of status epilepticus developed several NCSE shortly after administration of tiagabine. This represents strong evidence of a causal relationship. Also, in experimental studies it has been shown that in higher doses a disequilibrium between glial and neuronal GABA uptake may aggravate the failure of GABA inhibition thus explaining this adverse side-effect.

Osteosclerotic metaphyseal dysplasia: a skeletal dysplasia that may mimic lead poisoning in a child with hypotonia and seizures.

We report the case of a 23-month-old male with hypotonia, developmental delay, and complex seizures. Radiographs revealed profound sclerosis of the metaphyses and epiphyses of the long and short bones in the extremities, with a unique pattern of distribution. Sclerosis also involved the anterior ribs, iliac crests, talus, and calcaneus. The skull and vertebral bodies appeared unaffected. Blood lead levels were normal. We believe that this constellation of clinical and radiographic abnormalities closely resembles osteosclerotic metaphyseal dysplasia (OMD) due to an autosomal recessive defect. Characteristic skeletal findings were instrumental in determining the diagnosis. OMD is a very rare sclerosing bone disorder, first described in 1993. The syndrome is characterized clinically by developmental delay of a progressive nature, hypotonia, elevated alkaline phosphatase, and late-onset spastic paraplegia. We encountered a young child with these neurologic symptoms who displayed sclerotic metaphyseal changes on hand radiographs obtained to determine the bone age. Lead poisoning, a known cause of metaphyseal sclerosis, was initially suspected. Careful analysis of the metaphyseal bone changes helped to distinguish this bone dysplasia from lead poisoning and other causes of metaphyseal sclerosis.

Comparison and correlation of surface and sphenoidal electrodes with simultaneous intracranial recording: an interictal study.

We prospectively compared and correlated interictal spikes recorded with simultaneous surface, sphenoidal, depth and subdural electrodes in 21 patients. Although the amplitude of sphenoidal spikes was often larger than that of surface spikes in patients with mesial basal temporal ictal and interictal foci, only 1 patient had exclusively sphenoidal spikes. Spikes with maximal amplitude at the sphenoidal electrode arose from mesial temporal, temporal neocortical and orbital frontal foci. An inferior vertical temporal dipole (hippocampal positive and inferior temporal neocortex negative) was associated with surface and sphenoidal spikes.

Functional significance of the mu rhythm of human cortex: an electrophysiologic study with subdural electrodes.

The existence of the mu rhythm and its general anatomical and physiological relationships are well known. There are few data, however, regarding the details of its anatomical and physiological specificity. We implanted fronto-temporal subdural electrode grids in 9 patients with intractable epilepsy to facilitate their surgical management. A 7-11 Hz cortical mu rhythm was observed in 5-16 electrodes located over the sensorimotor cortex as mapped by electrical stimulation. The mu rhythm was blocked by contralateral face and arm movements, passive movements of contralateral arm, and by ipsilateral arm movements. There was correspondence between the body area movement of which blocked the mu at a given site and the body region that was affected by stimulation at the same site. Power spectral analysis showed an overall decrease in power in all frequency bands. This was less prominent in the 14-100 Hz band resulting in a relative increase in high frequency power in association with movement. We conclude that both the presence and blocking of mu rhythm are specific to the somatic representation of the cortex from which it is recorded. Its functional significance may be similar to other sensory rhythms like the occipital alpha rhythm.
