title: [Tropical African neuromyelopathies: 61 studied cases in the Ivory Coast].
abstract: Sixty one cases of tropical myeloneuropathies (TNM) from Abidjan, Ivory Coast, are reported. The mean age of patients was 35 years. The socioeconomic level was often very low and puerperality was a common initiating factor. Several clinical forms are noted: pure pyramidal (16 cases), pure ataxic (11 cases), sensory motor polyneuritis (8 cases), combined sclerosis of the spinal cord (1 case), ataxic polyneuritis (25 cases). In fact the extent of the pathobiological process was more severe as shown by slowings of peripheral motor nerve conduction velocities, prolonged central conduction time determined after cortical and spinal stimulations, and a severe sensory axonal impairment on nerve biopsies. These changes were observed with varying degrees in all clinical forms. As long as the etiological factors of TMN are not known (preventing from the possibility to split this disease in several entities) it is preferable to speak about one global disorder and not isolated various clinical forms (e.g. particulary: tropical spastic paraplegia). HTLV-I retrovirus seems to play a limited role in the etiology of TMN in Ivory Coast (1 positive case).
