1/466. Transient paralytic attacks of obscure nature: the question of non-convulsive seizure paralysis.Eleven patients with transient paralytic attacks of obscure nature are described. paralysis could involve face or leg alone, face and hand, or face, arm and leg. The duration varied from two minutes to one day. Four patients had brain tumors, six probably had brain infarcts, and one a degenerative process. The differential diagnosis included TIAs, migraine accompaniments, and seizures. In the absence of good evidence for the first two, the cases are discussed from the standpoint of possibly representing nonconvulsive seizure paralysis (ictal paralysis, inhibitory seizure paralysis or somatic inhibitory seizure). Because of the difficulty in defining seizures as well as TIAs and migraine in their atypical variations, a firm conclusion concerning the mechanisms of the spells was not attained. Two cases of the hypertensive amaurosis-seizure syndrome have been added as further examples of ictal deficits.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/466. MR and CT imaging in the Dyke-Davidoff-Masson syndrome. Report of three cases and contribution to pathogenesis and differential diagnosis.Cerebral hemiatrophy or Dyke-Davidoff-Masson syndrome is a condition characterized by seizures, facial asymmetry, contralateral hemiplegia or hemiparesis, and mental retardation. These findings are due to cerebral injury that may occur early in life or in utero. The radiological features are unilateral loss of cerebral volume and associated compensatory bone alterations in the calvarium, like thickening, hyperpneumatization of the paranasal sinuses and mastoid cells and elevation of the petrous ridge. The authors describe three cases. Classical findings of the syndrome are present in variable degrees according to the extent of the brain injury. Pathogenesis is commented.- - - - - - - - - - ranking = 0.78284513370819keywords = brain, brain injury, injury (Clic here for more details about this article) |
3/466. Suspected carbamazepine-induced hepatotoxicity.carbamazepine is a potent anticonvulsant agent with proven efficacy in the treatment of partial and tonic-clonic seizures. An epileptic child treated with therapeutic dosages of carbamazepine developed severe hepatitis and hepatic insufficiency. She had a positive response to withdrawal of the drug and administration of corticosteroids. The Roussel UCLAF method for estimating causality of the adverse event was applied for an acute hepatocellular problem, with a final score of 8. This method has advantages over other tools because it involves many clinical factors that give additional guides to clinicians in patients with liver injury, but it must be adapted for adverse events in the pediatric population.- - - - - - - - - - ranking = 0.012919482418632keywords = injury (Clic here for more details about this article) |
4/466. Continuous EEG monitoring in the intensive care unit: early findings and clinical efficacy.The assessment of the neurocritical care patient involves serial assessment of neurologic status using bedside clinical examination and a variety of periodic neurophysiologic testing. Continuous electroencephalographic (CEEG) monitoring in the intensive care unit offers a unique means to track neurologic function directly and regionally. CEEG is becoming more widespread with a growing but small body of literature. The purpose of this paper is to outline the current experience with intensive care unit CEEG monitoring. The basic methods and caveats are discussed. We review the underlying rationale for using CEEG which is that secondary neurologic injury commonly occurs in the intensive care unit and at times is hard to detect. CEEG has a proven role in detecting secondary injuries, namely seizures and brain ischemia. The basic tenets of establishing clinical effectiveness for CEEG in the ICU are discussed while acknowledging a need for further study of clinical effectiveness. We review our initial clinical experience of CEEG in 300 patients and outline the clinical efficacy in terms of cost reduction and improvement in outcome (P < 0.01) using CEEG. Finally, several controversial aspects of CEEG are enumerated, and the need for additional study to answer these pressing questions is presented.- - - - - - - - - - ranking = 0.51291948241863keywords = brain, injury (Clic here for more details about this article) |
5/466. Behenoyl cytarabine-associated reversible encephalopathy in a patient with acute myelogenous leukemia.We report a case of reversible encephalopathy syndrome in a 16-year-old girl with acute myelogenous leukemia (AML), who is undergoing during consolidation chemotherapy composed of BH-AC (N4-behenoyl-1-beta-D-arabinofuranosyl cytosine) and idarubicin. On the 6th day of chemotherapy, she was in a drowsy state following generalized tonic clonic seizure lasting 20 minutes. MR images revealed extensive cortical and subcortical white matter brain edema. Alertness returned over the 24 hr following by the discontinuation of BH-AC and intravenous administration of diphenylhydantoin, although she complained of intermittent headaches and visual disturbance. She gradually recovered from these symptoms during subsequent 7 days. Previously noted abnormal signal intensities have nearly disappreared on follow-up MRI obtained on the 22nd day after the first seizure. She was discharged without any neurologic sequela. This case suggests that BH-AC, a derivative of cytosine arabinoside (1-beta-D-arabinofuranosylcytosine) could be a cause of reversible encephalopathy syndrome.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
6/466. tremor and seizures associated with chronic manganese intoxication.tremor and seizures developed in a 2-year-old girl receiving total parenteral nutrition. T1-weighted images on MRI revealed areas of hyperintensity in the basal ganglia, brainstem and cerebellum. blood manganese was elevated. The symptoms and MRI abnormalities disappeared after withdrawal of manganese administration. The recommendation of daily parenteral manganese intake was discussed.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
7/466. Terminal deletion, del(1)(p36.3), detected through screening for terminal deletions in patients with unclassified malformation syndromes.We report on a 4 year-old girl with a 1p36.3-pter deletion. Clinical findings included minor anomalies of face and distal limbs, patent ductus arteriosus, the Ebstein heart anomaly, and brain atrophy with seizures. Conventional GTG-banded chromosome analysis revealed a normal (46,XX) result. Subsequent analysis by fluorescent in situ hybridization (FISH) using distal probes demonstrated a deletion of 1p36.6-pter. Molecular investigations with microsatellite markers showed hemizygosity at three loci at 1p36.3 with loss of the paternal allele. The deletion of 1p36.3 is difficult to identify by banding alone; indeed, our patient represents the third reported case with a del(1)(p36.3) that was detected only after more detailed analysis. In all three cases the deletion was detected through screening of patients with multiple congenital anomalies/mental retardation syndromes suggestive of autosomal chromosome aberrations for subtelomeric submicroscopic deletions by means of FISH or microsatellite marker analysis. On the basis of these observations we highly recommend that FISH with a subtelomeric 1p probe be routinely performed in patients with similar facial phenotype, severe mental retardation and seizures, and a heart malformation, particularly the ebstein anomaly.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
8/466. Operative treatment of tentorial herniation in herpes encephalitis.herpes simplex virus is the most common cause of acute viral encephalitis in children. Due to the variety of possible clinical manifestations the diagnosis is often overlooked in the early stages of the disease. Anti-viral therapy with acyclovir should be started whenever HSE is suspected. When there is further deterioration under virostatic therapy, a brain biopsy should be performed to verify the diagnosis. But even when the adequate medical therapy is established, massive brain edema and brain shift resulting in tentorial herniation can develop. Up to now the reported mortality of these patients is still around 30%. Here we report on a child with severe necrotizing herpes simplex encephalitis who developed severe tentorial herniation due to a right-sided mass lesion. The patient's status markedly improved after decompressive anterior temporal lobe resection. To our knowledge a similar case has not yet been reported in the literature. We suggest that anterior temporal lobe resection and decompressive craniotomy is of benefit in selected cases with tentorial herniation because both decompression and reduction of infectious material can be achieved.- - - - - - - - - - ranking = 1.5keywords = brain (Clic here for more details about this article) |
9/466. Severe cerebral venous sinus thrombosis and dural arteriovenous fistula in an infant with protein s deficiency.A 12-month-old infant presented with cerebral seizures and neurological deficits. MRI scan of the brain and angiography showed massive cerebral venous sinus thrombosis complicated by a dural arteriovenous fistula. Subsequent clotting analysis revealed a protein s deficiency. Screening for inherited coagulation inhibitor deficiency is recommended in children with unexplained or atypical thrombotic events.- - - - - - - - - - ranking = 0.5keywords = brain (Clic here for more details about this article) |
10/466. Behavioral psychophysiological intervention in a mentally retarded epileptic patient with brain lesion.Behavioral psychophysiological treatment entailing Slow Cortical Potential (SCP) biofeedback training and behavioral self-control training was conducted with a 27-year-old male epileptic patient (seizures for 23 years) with Wechsler IQ 64 who underwent callosotomy. The patient had 12/week secondary generalized tonic-clonic seizures. The treatment, consisting of 43 SCP training sessions and 22 behavioral control sessions, yielded a highly significant reduction of seizure frequency to about 7.5/week; such a decrease had never been observed after administration of new anticonvulsant drugs, nor after the callosotomy. During SCP feedback training, the patient was able to produce highly-significant cortical differentiation of SCPs of about 4 microV. In addition, he developed several new behaviors indicating growing ability of self-perception and self-regulation. These findings suggest that a combination of SCP biofeedback with behavioral treatment of epilepsy can be used even in mentally retarded patients with organic brain disorders.- - - - - - - - - - ranking = 2.5keywords = brain (Clic here for more details about this article) |
