From a statistical point of view, in less than 100 glioblastoma cases will a meningioma be simultaneously present in the brain. We report three cases with this coincidence and display the results of CGH and chromosome analysis in two patients, in whom the tumors arose in very close spatial correlation to each other.Patients: We describe three case histories with simultaneous occurrence of meningioma and glioblastoma as shown by MRI on admission. After neurosurgical removal of mass lesions, specimens from two patients were cultivated in cell culture and the cells were examined for chromosomal aberrations by conventional karyotyping as well as comparative genomic hybridization (CGH).Results: Examinations disclosed characteristic genetic aberrations for one meningioma and two glioblastomas. In one patient it was possible to compare the data for the meningioma and the glioblastoma; in this case we did not find a common genetic aberration in tumor cells with a different histology.Conclusion: Genetic testing of tumor cells should be performed routinely when different histological types of brain tumors are present in a close spatial relationship. We favor the hypothesis of statistical coincidence for the simultaneous occurrence of the two tumors rather than a common pathway giving rise to two tumor entities.","PeriodicalId":50708,"journal":{"name":"Zentralblatt Fur Neurochirurgie","volume":"68 3","pages":"145-50"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2007-981673","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26859675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of microsurgical techniques in the sixties contributed significantly to the progress in nerve repair. Since then, no major clinical innovation has become established. However, with an increased understanding of cellular and molecular mechanisms underlying nerve regeneration, various tubulization concepts have been developed which yield possible alternatives to direct suturing and to autologous nerve grafting in cases of short nerve defects. The vast knowledge gathered in the field of nerve regeneration needs to be further exploited in order to develop alternative therapeutic strategies to nerve autografting, which can result in donor-site defects and often lead to inappropriate results. Considering the encouraging results from preclinical studies, innovative nerve repair strategies are likely to improve the outcome of reconstructive surgical interventions. This paper outlines, in addition to the fundamentals of nerve regeneration, the current treatment options for defects of peripheral nerves. This article also reviews the developments in the use of alternative nerve guides and demonstrates new perspectives in the field of peripheral nerve reconstruction.","PeriodicalId":50708,"journal":{"name":"Zentralblatt Fur Neurochirurgie","volume":"68 3","pages":"101-10"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2007-984453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26859228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But recent publications suggest that titanium implants can be used safely in infectious sites in combination with debridement and antibiotic therapy. The purpose of this study is to provide further evidence in support of debridement and instrumentation as a single-stage procedure for spinal infection.Methods: Twenty-four cases with cervical, thoracic, and lumbar spondylitis/spondylodiscitis were analyzed. In 17 cases, anterolateral stabilization was performed with titanium cages. No autologous or homologous bone grafts were used. Transpedicular screw/rod fixation following posterior debridement of the intervertebral space was performed in the other 7 cases.Results: WBC and C-reactive protein levels decreased significantly after surgical debridement. Pain levels decreased from a preoperative median of 4 (on the Denis Pain Scale) to a postoperative median of 2. Twenty-two of the 24 patients were fully mobilized within 2 weeks after surgery. The Barthel Index improved from 60 (10-85) before surgery to 90 (65-100) after surgery. No recurrence of the initial infection was noticed during a mean follow-up period of 18 months. The fusion rate was 90.5%. The mortality rate was 1 out of 24 (4.2%).Conclusions: These findings support the position that debridement and instrumented fusion can be performed as a single-stage procedure without an increase in the recurrence rate or morbidity, compared with the use of autologous bone grafting or staged procedures. Same-stage instrumentation allows early postoperative mobilization of the patient, which is advantageous, especially for an increasingly elderly population and in patients with comorbidities.","PeriodicalId":50708,"journal":{"name":"Zentralblatt Fur Neurochirurgie","volume":"68 3","pages":"123-32"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2007-984461","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26859229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is, however, debatable whether a plate is really necessary to increase the progress of fusion. Thus, the aim of this randomized and controlled prospective study was to evaluate whether ACDF with a cage and anterior plate fixation results in a greater progress of fusion compared with ACDF using a stand-alone cage.Methods: 37 candidates for ACDF were treated either with a stand-alone cage (study group) or with a cage+plate fixation (control group). 19 patients were randomized to be stabilized with a stand-alone cage and 18 patients were treated with a cage and additional anterior plate fixation. The progress of cervical fusion over time was compared by radiostereometric analysis (RSA). Follow-up examinations pre- and postoperatively were done using the Visual Analogue Scale (VAS) for neck and arm pain. Radiographic assessment of fusion using an RSA-control was done after one, six and twelve weeks, as well as after six months, and one and two years postoperatively. Mann-Whitney test for unpaired values was used to determine the statistical differences in residual intervertebral motion.Results: Three-dimensional analysis of segmental motion (left-right, cranio-caudal, and posterior-anterior) did not reveal any statistical differences between both groups at any examination time postoperatively ( P>0.05). The VAS score did not differ between the groups ( P>0.05).Conclusion: Anterior plate fixation did not demonstrate an improvement in the progress of fusion in one-level ACDF.","PeriodicalId":50708,"journal":{"name":"Zentralblatt Fur Neurochirurgie","volume":"68 3","pages":"133-8"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2007-984462","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26859230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Simpson grade I resection was achieved in seven patients (58%) and none of these patients developed local tumour recurrence after a mean follow-up period of 127 months (10.6 yrs). Only one of these patients received adjuvant radiotherapy. A recurrence of the HPC was observed in all patients (42%) who underwent subtotal tumour resection at first surgery (Simpson grade II or higher). Recurrences occurred after a mean period of 39 months (3.2 yrs) after primary surgery and were effectively controlled by surgical excision, radiotherapy and gamma knife radiosurgery. Two patients (17%) developed extraneural metastases which were treated by surgical excision, radiotherapy and salvage chemotherapy.

Authors of some recent series have advocated total removal with SSS reconstruction. However gamma-knife surgery is a reasonable choice for these tumors.Patients: This study focused on 43 cases of meningioma invading the SSS that were treated with gamma-knife therapy. Twenty-eight patients had undergone previous resection. The follow-up period after radiosurgery ranged from 24 to 86 months (median, 46 months). The median marginal dose was 15 Gy.Results: During follow-up, 22 (51%) tumors decreased in size, 16 (37%) remained unchanged, and 5 (12%) expanded. The overall rate of tumor control with radiosurgery was 89%.Conclusion: When a small meningioma involves the SSS and the sinus is patent, the first-line treatment should be radiosurgery. If the tumor is large and the sinus is patent, we recommend gross total resection with no removal of SSS. If postoperative or follow-up MR imaging demonstrates residual tumor or recurrence, gamma-knife surgery should be performed. If a large meningioma has completely obliterated the SSS, our policy is to remove the tumor and all sinus tissue without reconstructing the SSS.","PeriodicalId":50708,"journal":{"name":"Zentralblatt Fur Neurochirurgie","volume":"68 2","pages":"73-8"},"PeriodicalIF":0.0,"publicationDate":"2007-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2007-977740","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26816199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
