1/127. Parenchymatous cerebral neurocysticercosis in a quadriplegic patient.OBJECTIVE: To present and discuss a case of cerebral neurocysticercosis in a quadriplegic patient. DESIGN: Case report of a case of neurocysticercosis in a high level spinal cord injury (SCI) patient who developed episodes of autonomic dysreflexia and orthostatic hypotension associated with transient neurologic deficits and seizures. SETTING: spinal cord Unit of the University Hospital of Geneva, switzerland. SUBJECT: Single patient case report. MAIN OUTCOME MEASURE: Clinical and radiological magnetic resonance imaging follow-up of the patient between July 1995 and October 1997. RESULTS: Treatment of cysticercosis with praziquantel relieved the patient from autonomic dysreflexia, symptomatic orthostatic hypotension, transitory neurological deficits and seizures. CONCLUSION: Diagnosis of neurocysticercosis in a quadriplegic patient might be difficult because of frequent overlaps with some usual symptoms occurring in high level SCI, mostly autonomic dysreflexia and orthostatic hypotension. neurocysticercosis should be kept in mind when a SCI patient living in, or coming from endemic zones presents with new neurological abnormalities and seizures. magnetic resonance imaging appears to be more sensitive than computerised tomography to confirm the diagnosis of active cysticercosis. Treatment with praziquantel associated with cimetidine to increase the drug bioavailability and prednisone to reduce the inflammatory reaction gives good results.- - - - - - - - - - ranking = 1keywords = seizure (Clic here for more details about this article) |
2/127. Successful bone marrow transplantation in a case of Griscelli disease which presented in accelerated phase with neurological involvement.Griscelli disease (GD) is a rare disorder characterized by pigment dilution, immunodeficiency and occurrence of accelerated phase consisting of hemophagocytosis, pancytopenia and neurological manifestations. Allogeneic BMT in the early period is an important modality of treatment for GD. We carried out an alloBMT from an HLA-identical sibling donor on a 4-year-old girl who presented in accelerated phase with neurological manifestations including convulsions, strabismus, severe dysarthria, ataxia and clonus. She was treated with etoposide, methylprednisolone and intrathecal methotrexate for 8 weeks and underwent alloBMT after receiving a conditioning regimen including ATG (rabbit, 10 mg/kg x 5 days), Bu/Cy. 8 x 108/kg nucleated bone marrow cells were given. Engraftment occurred early and the post-BMT period was uneventful. Currently, she is at 18 months post BMT with sustained engraftment and with a normal neurological examination except for minimal clonus. Long-term follow-up will determine the prognosis regarding the neurological findings.- - - - - - - - - - ranking = 0.063053880805479keywords = convulsion (Clic here for more details about this article) |
3/127. Isolated sulfite oxidase deficiency: review of two cases in one family.OBJECTIVE: The authors describe two cases of isolated sulfite oxidase deficiency found in one family. This is a rare autosomal-recessive disorder presenting at birth with seizures, severe neurologic disease, and ectopia lentis. It can be easily missed with metabolic screening; however, the finding of lens subluxation stresses the importance of ophthalmic assessment in making the diagnosis. DESIGN: Two observational case reports. INTERVENTION/methods: Ophthalmic assessment, biochemical assay for specific urinary and plasma metabolites, magnetic resonance imaging, and gene sequencing were used to make the diagnosis of the disease in the proband. The diagnosis was subsequently recognized in a previously affected sibling after the postmortem neuropathology was reviewed. mutation analysis was performed on cultured fibroblasts from the proband to identify and categorize the specific mutation responsible for the disease in the family. From this, future prenatal detection of sulfite oxidase deficiency is possible. MAIN OUTCOME MEASURES: The diagnosis of sulfite oxidase deficiency was established in this family, enabling appropriate genetic counseling and recurrence risk estimation. RESULTS: Point mutations were found in both alleles of the sulfite oxidase gene in the proband. The first is a 623C-->A mutation, which predicts an A208D substitution, and the second is a 1109C-->A, which predicts an S370Y substitution. Both residues A208D and S370Y are critical for sulfite oxidase activity. CONCLUSIONS: Isolated sulfite oxidase deficiency is a rare heritable disease for which mutation analysis can allow accurate prenatal screening. It often is difficult to diagnose by clinical presentation alone, but the critical finding of lens subluxation accompanying seizures and diffuse neurologic disease in an infant should alert the physician to the diagnosis.- - - - - - - - - - ranking = 0.66666666666667keywords = seizure (Clic here for more details about this article) |
4/127. biotinidase deficiency--a treatable entity.biotinidase deficiency is a well recognised treatable cause of a wide spectrum of progressive neurological symptoms. Recent reports have stressed the need to screen children with early onset of seizures, encephalopathy, neurodevelopmental delay, skin rash and alopecia. Enzyme estimation remains the conclusive test. We present a patient with biotinidase deficiency suspected on the above clinical grounds and diagnosed on the basis of metabolic acidosis, raised blood lactate, ketonuria and positive dinitrophenylhydrazine (DNPH) test and confirmed on urinary organic acid profile. Supplementation with biotin resulted in marked clinical improvement and normalisation of metabolic parameters. Thus the clinician should be alert to simple clinical pointers which aid in early diagnosis of these disorders.- - - - - - - - - - ranking = 0.33333333333333keywords = seizure (Clic here for more details about this article) |
5/127. angelman syndrome in three adult patients with atypical presentation and severe neurological complications.angelman syndrome (AS) is a distinct neurogenetic disorder and the phenotype is well known in childhood and adolescence. However, with advancing age the clinical and behavioral phenotype changes. In adulthood, the phenotype can be rather aspecific. We report on AS in 3 severely to profoundly mentally retarded patients, who developed severe neurologic complications of severe tremor, spasticity and coordination problems, resulting into severe loss of function. They presented atypical craniofacial features, short stature, epileptic seizures, microcephaly, brachytelephalangy and absent speech. Two patients presented at an older age a change in day-night rhythm. Based on this experience, we conclude that all severely to profoundly mentally retarded patients with atypical phenotype, spasticity, absent speech, epileptic seizures and changed day-night rhythm are candidates for further cytogenetic and molecular investigation for AS. Clinical photographs of the patient at a younger age can be helpful. The presence of the typical EEG pattern with frontal triphasic delta waves may direct to the diagnosis of AS.- - - - - - - - - - ranking = 0.66666666666667keywords = seizure (Clic here for more details about this article) |
6/127. Neurological symptoms in patients whose cerebrospinal fluid is culture- and/or polymerase chain reaction-positive for mycoplasma pneumoniae.We describe 13 patients with neurological signs and symptoms associated with mycoplasma pneumoniae infection. M. pneumoniae was isolated from the cerebrospinal fluid (CSF) of 9 patients: 5 with meningoencephalitis, 2 with meningitis, and 1 with cerebrovascular infarction. One patient had headache and difficulties with concentration and thinking for 1 month after the acute infection. M. pneumoniae was detected, by means of PCR, in the CSF of 4 patients with negative culture results. Two had epileptic seizures, 1 had blurred vision as a consequence of edema of the optic disk, and 1 had peripheral nerve neuropathy.- - - - - - - - - - ranking = 0.33333333333333keywords = seizure (Clic here for more details about this article) |
7/127. Neurologic symptoms in children with systemic lupus erythematosus.Neurologic complications of systemic lupus cerebritis are not as well known in children as in adults. Twenty-five children with neurologic complications were identified after reviewing the hospital medical records of 86 children with systemic lupus erythematosus. Seven children (28%) had neurologic symptoms at the time of initial diagnosis of systemic lupus erythematosus; median time between diagnosis of systemic lupus erythematosus and onset of neurologic complications was 1 month (range 0-5 years). seizures were the most common neurologic symptoms overall, but headaches were the most frequent neurologic manifestation in children without a previous diagnosis of systemic lupus erythematosus. Sixteen children had seizures, and 12 children had seizures as the initial central nervous system involvement. Almost all children who developed seizures had an established diagnosis of systemic lupus erythematosus; only one child had seizures that led to the diagnosis of systemic lupus erythematosus. No patient had status epilepticus, and, in general, seizures were not difficult to control. In six children, headache was the initial symptom of central nervous system involvement. Five children had lupus cerebritis, three children had stroke, and two had isolated cranial neuropathies. chorea was seen in only two cases, and three children had pseudotumor cerebri. Treatment with high-dose intravenous methylprednisolone led to a good response in 18 children; cyclophosphamide was required in 6 patients and plasmapheresis in 1 child. Outcome was generally good, although one child developed fulminant cerebritis with intracranial hypertension and died.- - - - - - - - - - ranking = 1.6666666666667keywords = seizure (Clic here for more details about this article) |
8/127. Absence of N-acetylaspartate in the human brain: impact on neurospectroscopy?N-acetylaspartate (NAA) contributes to the most prominent signal in proton magnetic resonance spectroscopy (1H-MRS) of the adult human brain. We report the absence of NAA in the brain of a 3-year-old child with neurodevelopmental retardation and moderately delayed myelination. Since normal concentration of NAA in body fluids is hardly detectable, 1H-MRS is a noninvasive technique for identifying neurometabolic diseases with absent NAA. This report puts NAA as a neuronal marker to question.- - - - - - - - - - ranking = 0.026197999281227keywords = impact (Clic here for more details about this article) |
9/127. Embolization of arteriovenous malformations with Onyx: clinicopathological experience in 23 patients.OBJECTIVE: To report our experience in treatment of arteriovenous malformations (AVMs) using a new liquid embolic agent, Onyx (Micro therapeutics, Inc., Irvine, CA). methods: Between January 1998 and May 1999, 23 patients (8 men and 15 women) were treated. The patients' average age was 40 years, with seizure being the most common presenting symptom (39%). The average Spetzler-Martin grade on presentation was 3. The average AVM volume before embolization was 14.5 cm3. RESULTS: We observed an average 63% reduction in AVM volume after 129 arterial feeders were embolized. There were four adverse events. Two patients experienced ischemia because of inadvertent occlusion of an arterial feeder. One of these patients made a full recovery, but the other patient had a permanent deficit. Two other patients experienced transient neurological deficits that resolved within 1 week of embolization. Permanent morbidity was thus 4% (1 of 23 patients). There were no deaths. Twelve patients underwent subsequent radiosurgery, and 11 patients had surgery that resulted in complete resection of their AVMs. Histopathological examinations showed mild acute inflammation in specimens resected 1 day after embolization. Chronic inflammatory changes were observed in specimens resected more than 4 days after embolization. In two patients, angionecrosis of the embolized vessels was noted. No evidence of parenchymal hemorrhage was observed in these patients, and vessel wall integrity was maintained as well. CONCLUSION: Onyx is a new nonadhesive liquid embolic agent that has been used to treat 23 patients at our institution with good results. Its nonadhesive nature and ease of use make it a promising agent in the future treatment of AVMs.- - - - - - - - - - ranking = 0.33333333333333keywords = seizure (Clic here for more details about this article) |
10/127. Bullous pemphigoid in a leg affected with hemiparesia: a possible relation of neurological diseases with bullous pemphigoid?We report a typical case of bullous pemphigoid (BP) associated with a neurological disorder and study a possible link between neurological disorders and BP. An 84-year-old hemiplegic woman presented with unilateral BP on the hemiparetic side. BP was confirmed by histological and immunofluorescence data. The medical records of the previous 46 consecutive patients with BP were retrospectively analyzed (average age: 79; median age: 85). Thirty of the 46 patients with BP had neurological disorders. These disorders included dementia, epilepsy, multiple sclerosis, cerebral stroke, Parkinson's disease, gonadotropic adenoma, trembling, dyskinesia, lumbar spinal stenosis. In a control group of the 46 consecutive oldest patients (older than 71; average age: 82,5; median age: 80) with another skin disease referred during the previous two-year-period to our one-day-unit only, 13 patients had a neurological disorder. This study demonstrates that there is a high prevalence of neurological disorders in patients with BP (p = 0.0004). A prospective case control study with neurological examination and psychometrical evaluation is warranted to confirm these data. We speculate that neuroautoimmunity associated with the aging process or neurological disorders may be involved in pemphigoid development via an autoimmune response against dystonin which shares homology with bullous pemphigoid antigen 1. Bullous pemphigoid could be considered to be a marker of neurological disorder.- - - - - - - - - - ranking = 0.2033096717322keywords = epilepsy (Clic here for more details about this article) |
