[Some aspects of occupational spinal diseases].

Prevalence of neurologic cervical and lumbar disorders among workers does not depend upon hardness of work conditions. First diagnosed occupational vertebral syndromes were clinically divided into reflectory and compression ones. Length of service, age and X-ray signs appeared not to differ significantly between the groups.

The critical role of 3-D CT reconstructions for defining spinal disease.

Three dimensional processing of routine CT images has previously been applied to osseous related maxillo-facial and spinal disorders. Two groups of patients, 25 with substantial spinal trauma and 25 with 'failed back' syndrome had 2-D and 3-D like displays processed by the Cemax 1000 system. The goal was to objectify whether the adjunct of 3-D imaging was truly valuable diagnostically. All images were recorded on 35 mm slides and projected both randomly and as an organized case; intra- and interpersonal evaluations were made. 3-D imaging in 19 of the 25 (76%) trauma patients disclosed additional diagnostic information which was considerably important to both the neuroradiologist and the referring surgeon. In the 'failed back' group, the 3-D images showed supplementary information in 15 of 25 (60%) cases. 3-D displays were usually in color showing complete regional information obtained from high resolution, medium thickness (4 mm) CT slices with minor overlapping (1 mm). The displays were optimized to the plane best defining the pertinent osseous and joint morphology; this included variably rotated and sometimes hemisected views. The images presented here are static, however, when viewed rapidly or by dynamic rotation, the regional morphology results in a highly graphic 3-D presentation.

[Peroneal muscle atrophy with talipes cavus. Pyramidal symptoms and sensory disorders in one family. On the problem of the nosological classification of hereditary spinal diseases and polyneuropathies].

We describe a family with peroneal muscular weakness and atrophy with associated pyramidal signs. Onset of obvious symptoms was usually after the age of 50 years, but history pointed to subtle symptoms at an earlier age. The disorder was of autosomal dominant inheritance. The muscle weakness involved only the legs. All affected persons remained independent as regards their ability to walk. Sensory disturbances were never significant for the affected individual. With regard to the neurographies, the disease could be classified as a form of hereditary motor and sensory neuropathy (HMSN). The clinical picture, however, allows the classification of the disease as a form of spinal muscular atrophy or spastic spinal paralysis. We discuss the diagnostic implications of such disorders, which involve both the peripheral and the central motor pathways.

[Spinal diseases and professional longevity of flying personnel].

Analyzed were histories of medically discharged (n = 727), physically qualified (n = 807), pilots and navigators, and flying personnel (n = 372) who had been repeatedly tested in one and the same hospital at the age of 34-36 yrs and 38-41 yrs. Spondylosis deformans is diagnosed more frequently in medically discharged than qualified flyers but, according to the covariation analysis, this is explained by elder age of the discharged persons. Physically fit persons with SD diagnosed at the age of 30-40 are prone to be grounded earlier than healthy persons. Compared with persons having other diagnoses, flying career (FC) will have longer if SD was stated at the age of 30, same if SD was stated at the age of 35, and shorter if SD was diagnosed at the age of 40. These differences remain statistically significant after covariation correction for specialty, age of entering military school and number of chronic diseases.
