[Essential tremor in Tunisia about 66 cases]

Essential tremor is a frequent hereditary disease beginning more frequently after the age of 65 years. It can be divided, following age at onset and familial history, into 3 groups: familial, sporadic and senile. Our series is composed of 22 patients suffering from familial essential tremor and 44 from senile type. We noted female predominance with a mean age of 70 years. The mean delay between the disease onset and the diagnosis confirmation is about 3 years. The bilateral form is frequent with significant symetric distal involvement of upper limbs comparatively to lower limbs. Drugs are indicated when tremor becomes important or handicapping. Meprobamate is well tolerated and constitutes an efficacious treatment

Apport de la tomodensitometrie cerebrale au cours du neuro-behcet [a propos de 50 cas]

The authors report a retrospective study of 50 CT Scan made for patients suffering from Behcet's disease with neurological manifestations. Neuro- Behcet can affect all the central nervous system structures with particular predilection to the brain stem, internal capsule and basal brain ganglia. The authors emphasize on the importance of CT Scan for the diagnosis, the severity evaluation of the neurological impairment and for the Neuro-Behcet's prognosis

Report of six cases of radiation myelopathy

The authors report six cases of radiation myelopathy observed after irradiation of 4 cases of cavum cancer,1 case of Hodgkin disease and 1 case of testicular seminomia. Radiation etiology of the myelopathy is diagnosed when the spinal cord is exposed to radiations, when there is coincidence between clinical signs level and irradiated medullary level, a free sufficient post radiotherapy interval and a lack of metastatic radiological signs. Chronic progressive radiation myelopathy is the most frequent with a mean beginning delay of 28.4 months clinical features of radiation myelopathy are frequently characterized by Brown sequard syndrome. This complication depend on different irradiation parameters as volume, dose and time factors, with an upper limit of 45 grays. Particular care must be taken for patients suffering from cavum cancer where irradiation ways are difficult and the other cancers where irradiation concerns an important length of the spinal cord with high doses. Systematic spinal somatosensory evoked responses for the patients who undergo spinal cord irradiation let to find infraclinical changes and modify treatment to avoid or decrease radiation myelopathy risks
