1/273. Lymphocyte transformation test for the evaluation of adverse effects of antituberculous drugs.The usefulness of the lymphocyte transformation test (LTT) for the analysis of adverse reactions to antituberculous drugs was evaluated. - The LTT was performed with isoniazid and rifampicin in 15 tuberculosis and 2 MOTT (Mycobacteria other than tuberculosis)-infection patients who suffered drug reactions, in 23 patients without any adverse reactions, in 7 controls previously exposed to antituberculous drugs, and in 14 controls who had never been exposed. 4/15 of the hepatotoxic reactions only showed a positive LTT with rifampicin, 3/15 only with isoniazid, and in 8/15 the LTT was negative. In an anaphylactoid shock reaction the LTT was extremely exaggerated for both rifampicin and isoniazid. In patients without any side effects only one slightly increased LTT due to isoniazid was observed. Two healthy controls with previous contact to these drugs showed a positive LTT for isoniazid, one of those with both rifampicin and isoniazid. The LTT was negative in all control persons without any former contact to antituberculous medications. In most cases hepatotoxicity seems to be a pure toxic reaction without the participation of cellular immune mechanisms. LTT can be useful for identifying the drug responsible for immunological side effects.- - - - - - - - - - ranking = 1keywords = person (Clic here for more details about this article) |
2/273. Can immunoadsorption plasmapheresis be used as the first choice therapy for neuroimmunological disorders?The subjects were 31 patients in whom immunoadsorption plasmapheresis (IAPP) was performed as the first choice therapy for primary or recurrent neuroimmunological disorders. The clinical manifestations before and after IAPP and the use of corticosteroids were investigated in the present study. IAPP was clinically effective in all patients. The corticosteroids (CSs) administration was begun or CSs were increased after completion of IAPP in 11 patients. IAPP was performed as the first choice therapy, and favorable results were obtained in patients with guillain-barre syndrome and Miller-Fisher syndrome. IAPP alone was also effective in a patient with lupoid sclerosis. When IAPP was used alone in 2 patients with chronic inflammatory demyelinating polyradiculoneuropathy, it completely eliminated the clinical manifestations, but the symptoms recurred about 2 months later. Therefore, although IAPP could be performed as the first choice therapy for many neuroimmunological disorders, subsequent therapies should be carefully investigated.- - - - - - - - - - ranking = 0.04446387380639keywords = ill (Clic here for more details about this article) |
3/273. Neurologic compromise after an isolated laminar fracture of the cervical spine.STUDY DESIGN: Report of a rare fracture of the cervical spine. OBJECTIVES: To illustrate the importance of the cervical spinolaminar line in the diagnosis of this unusual injury and to comment on appropriate investigations, management, and outcome. SUMMARY OF BACKGROUND DATA: Laminar fractures of the cervical spine are uncommon and are often missed. They usually occur after a hyperextension injury. It is unusual for these injuries to cause neurologic compromise. The injury reported here differs in that it was a result of direct trauma to the posterior aspect of the neck, and there was a significant neurologic deficit. methods: The clinical findings, roentgenographic appearance, treatment, complications, and follow-up assessment are presented and discussed. RESULTS: Initial neurologic examination revealed a right hemiparesis. Radiographs showed disruption of the spinolaminar line at C5 and a computed tomography scan revealed a fracture of the lamina of C5 with spinal canal encroachment. Management included high-dose corticosteroid administration and a posterior spinal decompression. The patient's initial postoperative course was complicated by acute pulmonary edema, which responded well to intravenous furosemide and ventilation. Follow-up assessment showed significant neurologic improvement. CONCLUSIONS: The satisfactory outcome in the case of this rare injury was the result of a prompt, accurate diagnosis and appropriate management.- - - - - - - - - - ranking = 0.022231936903195keywords = ill (Clic here for more details about this article) |
4/273. A case of paroxysmal tonic upgaze of childhood with ataxia.Paroxysmal tonic upgaze of childhood is a rare, distinctive, childhood syndrome that may be associated with ataxia and sometimes strabismus or amblyopia. Neurological examination as well as metabolic studies, electroencephalogram and neuroradiological investigations are normal in these patients. Although it has been considered as an age-related, dopa-sensitive dystonia, the exact pathogenetic mechanism is still unknown. Aggravation of attacks by fatigue, intercurrent infection or vaccination, and possible corticomesencephalic dysmaturation may underlie this abnormality. We report on a sporadic case of paroxysmal tonic upgaze with ataxia in which there was prompt aggravation of symptoms with sleep without response to levodopa treatment. This case suggests a different underlying pathogenetic mechanism from dopaminergic pathways for this syndrome.- - - - - - - - - - ranking = 0.022231936903195keywords = ill (Clic here for more details about this article) |
5/273. 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 = 0.022231936903195keywords = ill (Clic here for more details about this article) |
6/273. Focal neurological manifestations following aberrant central venous catheter placement.An infant developed focal tonic clonic movements of both lower limbs while receiving total parenteral nutrition through a left saphenous percutaneous central venous catheter. Radiographic studies using a contrast confirmed that the catheter tip was located in the ascending lumbar vein in close proximity to the epidural space. Withdrawal of the catheter abated all clinical symptoms. This case emphasizes the need to confirm central venous catheter placement and illustrates yet another risk associated with the infusion of parenteral alimentation.- - - - - - - - - - ranking = 0.022231936903195keywords = ill (Clic here for more details about this article) |
7/273. Neurological sequelae after lithium intoxication.Severe lithium intoxication was seen in a 57-year-old woman despite close monitoring of blood lithium levels over 23 months. High blood lithium levels were aggravated by drug induced hyponatremia. Neurological sequelae were still present six months after admission,- - - - - - - - - - ranking = 0.022231936903195keywords = ill (Clic here for more details about this article) |
8/273. Chronic relapsing thrombocytopenic purpura with severe neurological manifestations and full recovery.Neurological complications in thrombotic thrombocytopenic purpura (TTP) are associated with poor prognosis and/or permanent damage. We report a young woman in whom the diagnosis of TTP was difficult because cardinal manifestations were absent at presentation. The patient relapsed, showing severe and dramatic neurological manifestations, including coma. She was treated with multiple therapeutic modalities and recovered fully with no neurological sequelae. The difficulties involved in the management of chronic relapsing TTP are discussed. In the absence of clear guidelines, patients are still subjected to different treatment modalities according to the personal opinions and approaches of physicians. Clearly, well-controlled clinical trials to address this problem are required.- - - - - - - - - - ranking = 1.0222319369032keywords = person, ill (Clic here for more details about this article) |
9/273. 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 = 0.022231936903195keywords = ill (Clic here for more details about this article) |
10/273. Organic syndromes diagnosed as conversion disorder: identification and frequency in a study of 85 patients.BACKGROUND: The percentage of patients initially diagnosed with a conversion disorder and later identified as having an organic disorder has been decreasing in recent studies. METHOD: Consecutive patients with a diagnosis of conversion disorder were referred for psychiatric diagnosis and treatment. research questions were: (1) What incidence of neurological disorder is revealed by neurological reassessment and by which diagnostic technique is the final diagnosis established? (2) What differences can be observed between true-positive and the false-positive results? RESULTS: Ten (11.8%) of the 85 patients examined appeared to suffer from a neurological disorder. In this sample, variables discriminating between the true positives and false positives were: (1) prior suspicion of neurological disorder; (2) older age at referral; (3) older age at onset of symptoms; (4) longer duration of symptoms; and (5) use of medication. Three variables contributed significantly to the prediction of organic disorder: prior suspicion of neurological disorder; age at onset of symptoms; and duration of symptoms. CONCLUSIONS: Although our results are in line with those of other recent studies, the percentage of false positives was still high. The data further emphasize the dangers of making a diagnosis of conversion disorder in the absence of positive evidence. It is important to continue to provide follow up for patients with a diagnosis of conversion disorder. Unfortunately, unreliable psychiatric indications, like certain behavioral characteristics, are still used in the diagnostic process. The results show that a general neurological examination is still a valuable diagnostic instrument in addition to modern diagnostic techniques.- - - - - - - - - - ranking = 0.066695810709585keywords = ill (Clic here for more details about this article) |
