[Rare cause of myoclonus with giant SEP's: methyl bromide poisoning. Apropos of a case with unilateral predominance].

Giant and asymmetric SEPs were recorded in a patient with predominantly unilateral, spontaneous and intention myoclonus due to voluntary intoxication with methyl bromide as soon as day 3 after intoxication. The N10 Erb's point potential, cervical N13 and scalp recorded P15 potentials were found to be normal in latency, morphology and amplitude. The somesthetic informations could be considered as normally processed up to the subcortical levels of the somatosensory pathways. The parietal cortical potentials N20 and P25 and the frontal cortical potentials P22 and N30, contralateral to myoclonus, were abnormally large. This suggests that myoclonus could be related with an abnormal reactivity of somatomotor and somatosensory cortices to the afferent volleys triggered by voluntary movements. The prerolandic components P22 and N30 were found to be relatively more enhanced than the parietal N20 and P15.

[A unusual manifestation of multiple sclerosis: sciatica].

The authors recall the possibility of a typical sciatica in multiple sclerosis and describe seven new cases. Their main clinical features are: early onset before any other signs of the disease, hyperalgic, paroxysmal, short, repetitive episodes, absence of mechanical or effort triggers, absence of improvement with rest or anti-inflammatory drugs, well defined course. The intra-medullar origin of these attacks is suggested by the clinical criteria and the aspect of evoked potentials of the lower limbs recorded in 2 of the 7 patients.

[Clinical and pathological study of a case of subacute combined degeneration of the cord with folic acid deficiency (author's transl)].

Clinical and pathological findings in a case of subacute combined degeneration of the cord are described. The patient was a severe alcoholic but there was no vitamin B12 deficiency. Lesions were similar to those observed in Lichtheim's disease. Biological tests demonstrated frank folic acid deficiency, with very low serum and red cells levels. Clinical features included only mild macrocytic anemia, and flexion quadriplegia after a period of disorders of equilibrium. Higher functions were unaffected. Apart from alcoholism, no other toxic or digestive causative factors were found.
