1/196. 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 = cyst (Clic here for more details about this article) |
2/196. Abnormal liver function tests following inadvertent inhalation of volatile hydrocarbons.The use of aerosols containing volatile hydrocarbons in conditions of poor ventilation can result in accidental overexposure which can cause central nervous system effects and hepatic injury. We present a case in which inadvertent usage of an adhesive spray used to make greeting cards resulted in vague neurological symptoms and abnormal liver function tests both of which fully resolved on discontinuation.- - - - - - - - - - ranking = 21.813015771412keywords = nervous system, central nervous system (Clic here for more details about this article) |
3/196. Apparent central nervous system depression in infants after the use of topical brimonidine.PURPOSE: To report two cases in which topical brimonidine resulted in apparent central nervous system depression and unresponsiveness in an infant. methods: review of two patients. An 11-day-old infant became lethargic and apneic after a single drop of brimonidine. These symptoms were reproduced after a second administration of brimonidine. A 5-month-old infant became lethargic and poorly responsive after receiving 1 drop of brimonidine in each eye. RESULTS: The first patient required admission to the hospital for medical stabilization. He recovered without sequelae. The second patient recovered spontaneously approximately 2.5 hours after administration of brimonidine. CONCLUSIONS: Topical brimonidine may be associated with central nervous system depression in infants. The use of brimonidine is not recommended in these patients until further data are available.- - - - - - - - - - ranking = 130.87809462847keywords = nervous system, central nervous system (Clic here for more details about this article) |
4/196. A case of Perlman syndrome: fetal gigantism, renal dysplasia, and severe neurological deficits.We report on a neonate presenting with polyhydramnios; macrosomia; macrocephaly; visceromegaly including bilateral nephromegaly, hepatomegaly, cardiomegaly; thymus hyperplasia; cryptorchidism; generalized muscle hypotonia; and a distinctive facial appearance. The clinical course was marked by severe neurodevelopmental deficits combined with progressive respiratory decompensation leading to death at the age 6 months. magnetic resonance imaging (MRI) disclosed a generalized cerebral atrophy with a marked deficit of the white matter. Renal ultrasound and MRI showed markedly enlarged kidneys with multiple small cystic lesions, a pattern indistinguishable from polycystic kidney disease. The postmortem kidney biopsy revealed dysplastic changes, microcysts, and a focal nephrogenic rest, characteristic features of the Perlman syndrome. In children with fetal gigantism, renal abnormalities, and neurological deficits, Perlman syndrome should be considered and may be confirmed by kidney biopsy.- - - - - - - - - - ranking = 0.3keywords = cyst (Clic here for more details about this article) |
5/196. Detection of skin over cysts with Spina bifida may be useful not only for preventing neurological damage during labor but also for predicting fetal prognosis.Spina bifida is one of the most common open neural tube defects. There are two common types of spina bifida cystica, myelomeningocele and meningocele. Special attention to the thickness of the cystic sac (presence of intact skin and subcutaneous tissue) on magnetic resonance imaging is advantageous for determination of whether the child will profit from cesarean section in order to prevent neurological change (infection and drying of nerve tissue) and for management of spina bifida (most meningocele) during the perinatal period. Furthermore, skin detection may help to predict the prognosis of spina bifida after birth. meningocele, with intact skin over the cyst, has a better clinical course than myelomeningocele. Some myelomeningoceles with neural tube defects in a lower position, also frequently having an intact skin over the cyst, have almost the same clinical course as a meningocele. From this, we hypothesize that a baby with spina bifida who has intact skin over the cyst might have a good prognosis neurologically. In this report, we concentrate attention on the skin over cysts in 3 cases (1 meningocele and 2 myelomeningoceles).- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
6/196. 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 = 43.626031542825keywords = nervous system, central nervous system (Clic here for more details about this article) |
7/196. Intramedullary neurenteric cysts of the spine. Case report and review of the literature.This case of a 68-year-old woman with a low-thoracic intramedullary neurenteric cyst is notable for clinical presentation, cyst location, intraoperative findings, and imaging characteristics. The patient's postoperative course was complicated by neurological deterioration and a neuropathic pain syndrome. Potential causes of these complications are discussed, as are possible ways to reduce the risk of their occurrence.- - - - - - - - - - ranking = 0.6keywords = cyst (Clic here for more details about this article) |
8/196. recurrence of acute disseminated encephalomyelitis at the previously affected brain site.BACKGROUND: Acute disseminated encephalomyelitis (ADEM) is a usually monophasic demyelinating disorder of the central nervous system. Recurrences pose a diagnostic challenge because they can be overlooked or suggest an alternative diagnosis. OBJECTIVE: To examine the frequency, nature, and outcome of recurrent ADEM. DESIGN: review of the medical records of patients diagnosed in our institution as having ADEM between January 1, 1983, and May 31, 1998. Recurrences were defined as appearance of new symptoms and signs at least 1 month after the previous episode. RESULTS: Five (24%) of 21 patients with ADEM developed recurrent disease episodes. In all, diagnosis was confirmed by brain biopsy. One patient had 4 disease episodes, 2 had 3, and the other 2 each had 2. recurrence appeared 1.5 to 32 months after initial presentation and involved the same brain territory in 6 of 9 recurrences in 3 of 5 patients. In 2 patients, recurrences included neuropsychiatric signs. A good response to corticosteroid therapy was observed in 10 of 13 of treated ADEM attacks: in 3 of the 4 treated initial events and in 7 of 9 recurrences. CONCLUSIONS: Recurrent ADEM may be more prevalent than previously recognized. patients who relapse tend to have more than 1 recurrence that usually involves, clinically and radiologically, a brain territory that was affected before and can simulate a space-occupying lesion that requires histologic diagnosis. Neuropsychiatric features may be the main presentation of a relapse. Since recurrent ADEM is a corticosteroid-responsive condition, awareness and early diagnosis are mandatory.- - - - - - - - - - ranking = 21.813015771412keywords = nervous system, central nervous system (Clic here for more details about this article) |
9/196. Navajo neurohepatopathy: a mitochondrial DNA depletion syndrome?Navajo neurohepatopathy (NNH) is an autosomal recessive disease of full-blooded Navajo children living in the Navajo Reservation of southwestern united states. Clinical features of NNH include peripheral and central nervous system involvement, acral mutilation, corneal scarring or ulceration, liver failure, and metabolic and immunologic derangement. The cause of NNH is unknown, but the clinical features of NNH are similar to those of patients with mitochondrial DNA (mtDNA) depletion. Therefore, we studied mtDNA concentration in the liver from 2 patients with NNH. Using histochemical, biochemical, and molecular techniques, we found evidence of mtDNA depletion, and we propose that the primary defect in NNH is in the nuclear regulation of mtDNA copy number.- - - - - - - - - - ranking = 21.813015771412keywords = nervous system, central nervous system (Clic here for more details about this article) |
10/196. adult-onset xeroderma pigmentosum neurological disease--observations in an autopsy case.xeroderma pigmentosum (XP) is an inherited disease with defective dna repair. patients develop skin cancer because of unrepaired dna damage produced by the ultraviolet radiation (UV) in sunlight. Many XP children also develop XP neurological disease (ND), consisting of sensorineural hearing loss (SNHL) and a primary neuronal degeneration of the central and peripheral nervous systems. Since the harmful UV in sunlight cannot reach the nervous system, the cause of the death of XP neurons has been hypothesized to result from the inability to repair their DNA that has been damaged by endogenous metabolites. Progressive XP ND originating in an adult has been identified in only a single case. Although clinically asymptomatic at the age of 47 years, the patient had audiometric evidence of a developing mild SNHL together with elicited signs and electrophysiologic evidence of a peripheral neuropathy. She died of metastatic endocervical adenocarcinoma at 49 years of age. We describe here the neuropathological findings in this patient, including examination of the inner ear. Despite clinical evidence of SNHL, there were no anatomic abnormalities of the inner ear. However, the dorsal root ganglia (DRG) showed ongoing neuronal loss. Our findings indicate that XP ND originating in this adult is, like XP ND in children, a primary neuronal degeneration that manifests first in the peripheral nervous system.- - - - - - - - - - ranking = 53.833681927564keywords = nervous system (Clic here for more details about this article) |
