BACKGROUND The frequency of the association between chronic demyelinating inflammatory polyneuropathy (CIDP) and central nervous system (CNS) demyelinating lesions is probably underestimated. OBJECTIVE To investigate the occurrence of combined central and peripheral demyelination in CIDP patients and to correlate visual evoked potential (VEP)(More)
UNLABELLED Autonomic nervous system disturbances such as pupillary abnormalities have rarely been evaluated in multiple sclerosis (MS). However, pupillary impairment is not uncommon in MS and its origin is still unclear. The aim of this study was to investigate pupillary disturbances in MS and to try to correlate pupillary defects with spinal cord and(More)
PURPOSE As corticosteroids appear to intervene in pathogenesis of central serous chorioretinopathy, ion transport changes within the retinal pigment epithelium (RPE) might be involved. Electrophysiological responses to corticosteroid administration were recorded in vivo and in vitro. METHODS Clinical study: The standing ocular potential was recorded(More)
OBJECTIVE The predictive value of electrophysiologic visual testing in Creutzfeldt-Jakob disease (CJD) was investigated, and the retinal pathologic findings in three cases are reported. BACKGROUND The fatal prognosis of CJD, its transmissibility, and the lack of treatment make early diagnosis essential in averting human-to-human transmission.(More)
INTRODUCTION Visual acuity loss and scotoma are not the only functional consequence of macular disease. Frequently, patients also complain of metamorphopsia. Such visual distortion should be taken into account when evaluating the potential benefit of surgical procedures in macular disease. The Amsler grid does not allow any quantified analysis. In addition,(More)
Cross-clamping of the descending aorta immediately below the subclavian artery may result in damage to the spinal cord. Despite various protective procedures, the risk of such damage cannot be entirely eliminated. In an experimental study with 47 pigs, the influence of various factors on the genesis of spinal cord damage was examined. The pigs were divided(More)
Ischemic spinal cord injury after cross-clamping of the descending aorta can occur independently of aortic disease. In a previous study we had shown a precipitous uniform fall of spinal surface oxygen tension downstream to the clamping site irrespective of level. In the present paper, the hemodynamic changes in the spinal and aortic collateral circulation(More)
PURPOSE To analyze clinical and paraclinical characteristics of recurrent isolated optic neuropathy. PATIENTS and method: In three university hospitals (Montpellier, Nimes, and Strasbourg), between October 2005 and September 2006, the charts of patients with corticosensitive recurrent isolated optic neuropathy and normal cerebral magnetic resonance(More)
Spinal cord injury is the most dreaded complication of operative procedures on the descending aorta. Our previous experimental study on pigs indicated that an increase in the cerebrospinal fluid pressure after aortic cross-clamping did not influence the occurrence of spinal cord injury. We therefore concluded that the cause of spinal cord injury after(More)
