Quarrels over aphasia are no recent phenomena and have not always been explicit. Lordat and Gall can be cited in this respect as well as Dax and Bouillaud. Reference is also made to Broca-Dax and Trousseau-Lordat. ⋯ However, his patience eventually ran out and he replied sharply to the comments of Dejerine on "images of language" and those of Dupré on "mental representations". Metaphorically speaking, it might be said that the gold medal was not awarded, Augusta Dejerine Klumpke took the silver, Dupré and André-Thomas shared the bronze, and Souques and Moutier each deserved a special mention. It might also be suggested that in 1908 the Society sketched out to a large extent the programme for research on aphasia for the century to come. (ABSTRACT TRUNCATE

Neurological sequelae reported after epidural anesthesia include epidural hematoma, spinal cord ischemic injury and lumbosacral nerve root injury. We describe here a case of monoplegia of the right lower limb associated with an ipsilateral loss of perception of pain and temperature following an epidural anesthesia. ⋯ Hypotension, vascular spasm, trauma, arteriosclerosis, pressure increase in the epidural space are potential causative mechanisms. Unilateral symptoms might result from injury to a sulcocommissural artery or an anterior spinal artery when duplicated.

Review Case Reports
[Motor neuropathy, putamen necrosis and optic nerve atrophy after acute methanol poisoning].
Optic neuropathy and putaminal necrosis are the most common sequellae of methanol poisoning. We report a case in a patient with a chronic motor neuro(no)pathy in addition to these neurological complications. Peripheral nerve and spinal cord disorders, related to methanol poisoning, are uncommon and probably underestimated.

Review Case Reports
[Bilateral intracranial subdural hematoma following lumbar puncture: report of a case].
A chronic, bilateral, intra-cranial subdural hematoma was diagnosed in a 28 year old man. A standard diagnostic spinal tap had been performed 6 weeks before. There was no other etiologic factor. ⋯ Outcome was fatal in 9 of them. The possibility of an intra-cranial subdural hematoma has to be considered in case of prolonged or unusual headache following a lumbar puncture, even with a headache-free period, knowing the emergency of the surgical therapeutic procedure. The most likely mechanism is subdural venous bleeding induced by the chronic intracranial hypotension due to the persisting lumbar meningeal wound.

Magnetic resonance imaging represents voxels (volume elements) of the body placed in a magnet, by their magnetization determined under various acquisition conditions weighting the contrast of the image by the density of free water protons and their relaxation times T1 and T2. Thus, the sensitivity in depicting lesions is high but pathological specificity is poor. Efforts are made to increase the diagnosis powerfulness of M. ⋯ R. diffusion imaging and functional M. R. I. are intensively under investigation for a better analysis of these different factors conditioning the reversibility of the patient disability.
