21/2677. Rapid thrombectomy of superior sagittal sinus and transverse sinus thrombosis with a rheolytic catheter device.thrombosis of the dural venous sinuses is a potentially lethal condition that remains a diagnostic dilemma. Clinical outcome is typically dependent on the timeliness of diagnosis and definitive treatment. We report a case of successful rapid thrombectomy of extensive thrombus within the superior sagittal and transverse sinuses using a rheolytic catheter device. This appears to be a promising treatment option, particularly in those patients who do not respond to other, more established, forms of therapy.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
22/2677. Successful cerebral artery stent placement for total occlusion of the vertebrobasilar artery in a patient suffering from acute stroke. Case report.A 64-year-old man suffering from crescendo brainstem symptoms due to acute total occlusion of the vertebrobasilar artery was successfully treated by cerebral artery stent placement. The total occlusion of a long segment of the vertebrobasilar artery was completely recanalized by implanting two flexible, balloon-expandable coronary stents. The patient's clinical outcome 30 days later was favorable. No complications occurred during or after the procedure. This therapeutic option may prove to be a useful means to revascularize an acute total occlusion of the vertebrobasilar artery.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
23/2677. Acute and reversible parkinsonism due to organophosphate pesticide intoxication: five cases.OBJECTIVE: To describe five patients who developed acute and reversible parkinsonism following organophosphate (OP) pesticide exposure, and to consider whether this syndrome represents a rare sequela of such exposure in genetically susceptible individuals. BACKGROUND: Several toxins are known to produce parkinsonism following acute exposure. Although case-control studies have implicated OP pesticides in the etiology of PD, acute parkinsonism following brief pesticide exposure has never been reported. methods: The authors describe the clinical syndrome affecting five patients who presented with recent OP exposure and symptoms of an acute akinetic-rigid syndrome. RESULTS: All patients developed parkinsonism that resembled PD clinically except for poor response to levodopa. Three genetically related patients were exposed to pesticides in a common environment before onset of parkinsonism; other family members remained unaffected. Other secondary causes of parkinsonism were excluded. Four patients recovered completely without treatment, and one patient was lost to follow-up. One patient experienced repeated episodes of parkinsonism with inadvertent reexposure to a pesticide-contaminated environment. CONCLUSION: The clinical course of these five patients suggests their syndrome represents a heretofore undescribed toxic effect of OP pesticides. Our observations strengthen epidemiologic studies implicating OP pesticides in the etiology of PD. A genetic susceptibility to OP pesticide-induced parkinsonism may account for three family members developing this syndrome.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
24/2677. Diffuse unilateral subacute neuroretinitis in europe.BACKGROUND: Diffuse unilateral subacute neuroretinitis is thought to be caused by a solitary helminth migrating within the subretinal space. Laser photocoagulation of the located worm is the preferred mode of therapy. methods: We describe the clinical and electrophysiological features of a case of a 15-year-old Caucasian male with a longstanding diffuse unilateral subacute neuroretinitis (DUSN), in whom two worms were seen in the fundus examination. Focal photocoagulation of the worms was applied as treatment. RESULTS: No signs of inflammation could be seen after treatment. Three months later, the patient was doing well. Follow-up examination 4 years later revealed an unchanged fundus appearance in the affected eye, with no evidence of progression of the syndrome. CONCLUSIONS: If a worm is identified in DUSN, focal laser treatment of the located area is the treatment of choice, regardless of whether fundus changes suggest late stages of the disease. However, the eye of the patient should be thoroughly examined to rule out the presence of more than one worm that might cause the failure of therapy.- - - - - - - - - - ranking = 2keywords = ms (Clic here for more details about this article) |
25/2677. Acute dysarthria induced by low dose methotrexate therapy in a patient with erythrodermic cutaneous T-cell lymphoma: an unusual manifestation of neurotoxicity.Neurotoxicity has been associated on rare occasions with methotrexate therapy. We now report the case of a 71-year-old man with erythrodermic cutaneous T-cell lymphoma who developed symptoms of dysarthria and inco-ordination within 1 month of the initiation of oral methotrexate; discontinuation of the therapy then resulted in a gradual resolution of the problems.- - - - - - - - - - ranking = 2keywords = ms (Clic here for more details about this article) |
26/2677. Acute cholestatic hepatitis associated with pravastatin.A 57-yr-old man presented with clinical and laboratory signs of acute cholestatic hepatitis. Symptoms had appeared 7 wk after he was started on pravastatin 20 mg/day for hypercholesterolemia. A full evaluation including ultrasound, computed tomography, endoscopic cholangiography, and liver biopsy confirmed the diagnosis of intrahepatic nonobstructive jaundice. The liver function abnormalities normalized 7 wk after cessation of therapy. pravastatin should be considered as a potential cause of cholestatic hepatitis with favorable clinical outcome after drug withdrawal.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
27/2677. pancreatitis caused by duodenal duplication.The authors present the investigations and surgical treatment of two cases of duodenal cystic duplication. abdominal pain and gastroesophageal reflux were the most important symptoms and signs associated with an history of recurrent acute pancreatitis. Computed tomography scan, ultrasound examination, and cholangiography confirmed preoperatively the diagnosis, and a transduodenal surgical approach was carried out in both children. A simple marsupialization of the cyst was performed in the former, and a sphincterotomy with papillosphincteroplasty was associated in the latter. The diagnosis was confirmed by microscopy, and both the children are asymptomatic after a 14 and 18 months of follow-up. This report focuses on the importance of the cholangiopancreatography for every child presenting with recurrent, unexplained bouts of acute pancreatitis, and underlines the technical surgical aspects on the basis of the anatomic identification of the malformation.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
28/2677. Cyamamezine-induced acute hepatitis after unique massive intake: a case report.Hepatotoxicity of cyamamezine, a phenothiazine structurally related to chlorpromazine, has been rarely documented. We report here a case of acute symptomatic hepatitis following a unique massive intake of cyamamezine in a suicide attempt and discuss the mechanisms of such injury.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
29/2677. Subacute encephalopathy after combination chemotherapy including moderate-dose methotrexate in a patient with gastric cancer.An episode of subacute encephalopathy after the infusion of a moderate dose of methotrexate (1500 mg/m2) (MTX) is reported in a young adult with metastastic gastric cancer. Weakness of the right arm, focal seizures, lethargy and confusion appeared on day 10. High signal intensity in periventricular white matter was observed on T2-weighted magnetic resonance imaging. Symptoms resolved spontaneously and completely after 48 h. We believe that this represents an unusual case of moderate-dose MTX-induced neurotoxicity in a patient with gastric cancer, which has not previously been reported.- - - - - - - - - - ranking = 1keywords = ms (Clic here for more details about this article) |
30/2677. Posterior circulation aneurysms. Technical strategies based on angiographic anatomical findings and the results of 60 recent consecutive cases.Ninety-eight patients with aneurysms of the posterior circulation were admitted to our department from 1993 to 1997. Sixty of them underwent microsurgical treatment, mostly in the acute stage of subarachnoid hemorrhage. Peri- and intraoperative management were carried out according to a structured treatment strategy. Special aspects of surgical technique included extradural selective anterior clinoidectomy for basilar head aneurysms, lateral suboccipital craniotomy and partial condylectomy without laminectomy for aneurysms of the vertebral artery or posterior inferior cerebellar artery, and a trans-Sylvian approach, as used in selective amygdalohippocampectomy, for aneurysms of the posterior cerebral artery. A careful angiographic evaluation of the aneurysms in relation to the neighboring important arteries and bony structures was essential for optimal surgical planning. Forty-nine patients (82%) made a good recovery by 3 months after surgery. The mortality was 7%.- - - - - - - - - - ranking = 9keywords = ms (Clic here for more details about this article) |
