[Osteosynthesis of the spine using Cotrel-Dubousset instrumentation. Contribution of x-ray computed tomography with 3D reconstruction]. / Ostéosynthèse du rachis par matériel de Cotrel-Dubousset (C-D). Apport du scanner avec reconstruction 3D.

3D reconstruction is of a great interest in the study of the osteosynthesis of the spine by C-D material, where MRI is impossible and CT usually artifacted. The results obtained by 3D reconstruction allow visualization of osseous, extra osseous (disks, ligaments...) and metallic structures.

[Effects of radiotherapy on the course of cerebral metastases: contribution of x-ray computed tomography]. / Effets de la radiothérapie sur l'évolution des métastases cérébrales: apport de la TDM.

The clinical and radiological responses after irradiation of brain metastases were compared in 50 patients. A complete response as evidenced by CT scan was achieved in 11 patients, whereas a clinical complete response was observed in 16 cases. There was only 35% agreement between the clinical and the radiological responses. In terms of patient survival, those in whom complete radiological response was obtained has a significantly longer survival time (p = 0.004). Therefore, in evaluating the treatment of brain metastases, it is preferable to determine both the clinical and the radiological responses. The latter seems to be more accurate and justifies the use of repeated CT scans in the follow-up of these patients.

[The pure visceral form of Niemann-Pick disease in children. Review of the literature apropos of a case]. / La forme viscérale pure de la maladie de Niemann-Pick chez l'enfant. Revue de la littérature à propos d'un cas.

The fortuitous discovery of a pulmonary miliary pattern in a asymptomatic child led the authors to the diagnosis of Niemann-Pick disease.
