    Discectomies of the lower cervical spine using interbody biopolymer (B.O.P.) implants (1989)
    Springer
    Acta neurochirurgica 96 (1989), S. 88-93 
    Details
    ISSN: 0942-0940
    Keywords: Cervical interbody fusion ; biopolymer implants ; biocompatible orthopaedic polymer ; BOP
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The authors report their experience with 150 cases of discectomies performed with interbody grafts using a copolymer (Biocompatible Orthopedic Polymer or BOP*). Made of N-Vinylpyrrolidone-Methylmethacrylate monomers, polyamide fibres and calcium gluconate. BOP is a biocompatible, biodegradable, osteoconductive matrix, easy to use and quite safe. These properties are quite well appreciated for cervical interbody grafting. After discectomy, stabilization of the spine is immediate, and fusion slowly occurs around and through the biopolymer within one year. The biomaterial avoids morbidity inherent in the harvesting of an autograft, as well as any limitations resulting from the use of allografts.

    Specific selection of osteosynthetic material in the treatment of thoracic or lumbar spinal injuries by the posterior approach (1986)
    Springer
    Acta neurochirurgica 81 (1986), S. 118-124 
    Details
    ISSN: 0942-0940
    Keywords: Thoraco-lumbar spine ; trauma ; osteosynthesis ; posterior approach
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The authors report 165 cases of thoraco-lumbar lesions with neurological dysfunction. All the patient were operated. They analyze the neurological and mechanical results and indicate the use of different osteosynthesis apparatus according to the type and level of lesions. Harrington's rods seem to give more precise repositioning while Roy Camille's plates give more stability. When the posterior wall of the spinal canal is intact, Kempf's compression rods can be used. Thoraxic spine injuries seem to be an indication for Harrington's rods, while lumbar injuries seem to call for Camille's plates.

    Percutaneous interbody osteosynthesis in the treatment of thoracolumbar traumatic or tumoural lesions (1990)

    ISSN: 0942-0940
    Keywords: Lumbordorsal spine ; interbody osteosynthesis ; percutaneous
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The authors describe a technique of percutaneous interbody osteosynthesis applicable to the dorsal and lumbar spine. 51 patients were so treated for different aetiologies:traumatic conditions (35 cases) andtumoural lesions (16 cases). The material used consisted of special instruments that are positioned in double obliquity by a percutaneous posterolateral approach. A posterior approach limited to the pathological focus was used jointly whenever a graft or a decompression was necessary (19 cases). Several types of anaesthesia were used (local, local-regional, general, neuroleptanalgesia). The patients benefited by the advantages that usually accompany percutaneous techniques. The advantages and limitations of the method are discussed.

    Tyrosine kinase activity of insulin receptors from an insulin-resistant patient with leprechaunism (1987)
    Springer
    Diabetologia 30 (1987), S. 631-637 
    Details
    ISSN: 1432-0428
    Keywords: Insulin receptor ; tyrosine kinase ; insulin resistance ; anti-receptor antibodies ; leprechaunism
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Defects in insulin receptor function can impair the response of target cells to insulin. Previously we have described an insulin resistant patient (leprechaun/Ark−1) with qualitative abnormalities in insulin binding suggestive of a structural defect in her insulin receptors. In the present work, we have studied the tyrosine kinase activity associated with insulin receptors from cultured Epstein-Barr virus-transformed lymphocytes. In studies of insulin receptors from leprechaun/Ark−1, we observed that both the magnitude and the dose-dependency of insulin's effect to stimulate the tyrosine kinase activity were normal. This suggests that the defect causing this patient's insulin resistance is independent of the receptor-associated tyrosine kinase. In the course of these studies, we noted that an anti-receptor antiserum (B−d) had a markedly decreased ability to immunoprecipitate insulin receptors from leprechaun/Ark−1. This observation further supports our previous conclusion that the insulin receptor from leprechaun/Ark−1 is abnormal in structure. Moreover, it emphasizes the importance of choosing anti-receptor antisera which are equally effective at immunoprecipitating receptors from both patients and normal subjects when the anti-receptor antisera are employed as reagents in investigations of receptors from insulin-resistant patients.

    Occult spinal dysraphism: neuroradiological study (1990)
    Springer
    Neuroradiology 31 (1990), S. 512-522

    ISSN: 1432-1920
    Keywords: Occult spinal dysraphism ; Lipoma ; Tethered cord ; Spinal cord ; Caudal regression syndrome ; Developmental mass lesions
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary We present a retrospective study of occult spinal dysraphism in 47 children aged 0 to 14 years, all studied with plain X-rays, 60% with CT and myelo-CT, and 40% with MR. We consider the classification and grading of these malformations, clinical, neuroradiological patterns, and indications for surgery. In the light of our findings and of the published data MR emerges as the key investigation. Only in a few cases of great anatomical complexity is it now necessary to perform CT and myelo-CT as well. A case in point is when the conus and thickened filum terminale are inextricably bound together and can no longer be considered separate structures. We propose the term “neurofibrous structure” to define the conus-thickened-filum-terminale unit when these structure are no longer distinguishable.

    Ependymomas of the posterior cranial fossa: CT and MRI findings (1995)
    Springer
    Neuroradiology 37 (1995), S. 238-243 
    Details

    Keywords: Key words Ependymoma ; Posterior cranial fossa ; Children ; Magnetic resonance imaging ; Computed tomography ; Brain tumours
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract We studied nine children with posterior cranial fossa ependymomas to identify specific neuroradiological features. Patients were studied preoperatively with CT and MRI; T1-, T2- and proton-density (PD)-weighted images were obtained. All children underwent surgery and a definite histopathological diagnosis was made. All the tumours grew into the fourth ventricle and caused dilatation of its upper part, which resembled a cap. All but one were separated from the vermis by a cleavage plane. In eight cases there was desmoplastic development through the foramina of the fourth ventricle, and five were heterogeneous due to necrosis and cystic change; one had a haemorrhagic area. In most cases the solid portion was isointense with grey matter on T1-weighted images, hyperintense on PD weighting, and isointense on T2-weighted images. On CT the tumour was isodense in six cases and calcification was detected in four. The presence of both desmoplastic development and a tumour/vermis cleavage plane in a posterior cranial fossa tumour isodense on CT is highly suggestive of ependymoma.
