Abstract
We report a patient with Leber hereditary optic neuropathy (G11778A mtDNA) and a severe demyelinating neuropathy, for which no other cause except his mitochondrial disorder could be found. The involvement of the peripheral nervous system of patients with LHON, in particular with a 11778 mtDNA, is discussed.

Abstract
Three male patients aged 82, 56 and 60 years presented with cognitive impairment and hemiparesis, weakness of the tongue and facial muscles, and pain and weakness of the left arm, respectively. They were found to have carcinoma of the prostate with cerebral, skull and cervical spine metastases. They were treated with hormonal therapy and local radiotherapy for bone metastases. The first patient died within 2 weeks, the second after 1.5 year, and the third was still alive after 6 years. The diagnostic work-up in men with unexplained neurological symptoms should probably include a rectal exam and assessment of prostate-specific antigen.

Abstract
Insulin-like growth factors (IGFs) play an important role in tumour growth and development. We hypothesized that this is also the case for medulloblastomas, which are highly malignant cerebellar brain tumours usually occurring in children. In these tumours the expression patterns of IGF-I and -II mRNA were studied. Tumour specimens obtained from 12 children and two adults at diagnosis were hybridized in situ with digoxigenin-labelled cRNA probes for hIGF-I and hIGF-II mRNAs. In all cases, tumour cells showed abundant expression of IGF-I mRNA. Nine of the 14 tumours showed variable but significant IGF-II expression. In these tumours, the hybridization signal almost exclusively colocalized with a subpopulation of Ki-M1P positive cells that were identified as ramified microglia (RM) cells. In the five tumours without IGF-II expression, microglia/brain macrophages with a more rounded amoeboid-like morphology predominated. RM cells in normal cerebellar tissues, residing abundantly in areas of the white and, to a less extent, in the grey matter, were IGF-II mRNA-negative. These RM cells showed a thinner and more extensively branched appearance and were more evenly distributed than those encountered in medulloblastoma. Probably, during the transformation from the resting ramified towards the amoeboid morphology (or vice versa) IGF-II mRNA expression is only temporarily induced. The physiological meaning of the induction of IGF-II mRNA expression by these cells in medulloblastoma remains unclear but any IGF-II peptide synthesized could exert unfavourable mitogenic and antiapoptotic effects on adjacent tumour cells. However, in this relatively small number of cases we could not find any indications for a relationship between clinical characteristics of the various cases and the extent of IGF-II mRNA expression.

Abstract
OBJECTIVE The goal of our study was to investigate the inverse correlation between number of genetic aberrations and malignancy grade in ependymal tumors at the ploidy level. METHODS we examined seven myxopapillary ependymomas (mpEs) (WHO grade I), 28 spinal and cerebral ependymomas (Es) (WHO grade II), and 18 cerebral anaplastic ependymomas (aEs) (WHO grade III) using image DNA cytometry. The ploidy status was correlated with clinicopathological characteristics and with the results obtained by comparative genomic hybridization (CGH) analysis that we performed in about half of these tumors. RESULTS mpEs were exclusively located in the spinal cord and aEs in the cerebrum only, whereas Es were located in both the spinal cord and brain. We found aneuploidy or tetraploidy to be common in the group of mpEs (6 out of 7) and much less frequent in Es (6 out of 28) and aEs (4 out of 18). Three-year postoperative survival was 100% for mpEs, 100% for spinal Es, 92% for cerebral Es, and 33% for aEs. Our CGH results in a selection of these tumors revealed the highest number of genetic aberrations in the mpEs (average 16; n = 2), a lower number in Es (average 12; n = 11) and the lowest number in aEs (average 5; n = 6). Interestingly, in the group of Es and aEs, a high number of genetic aberrations as detected by CGH was not correlated with aneuploidy or tetraploidy. Three patients, all with mpEs had local seeding. CONCLUSION These results underline that mpEs are distinctly different from Es and aEs at the genetic level and that extensive genomic alterations and aneuploidy in ependymal tumors are not in itself an indicator of malignant behavior.

Abstract
Three patients, two women aged 72 and 45 years, and a man aged 80 years, presented with transient neurological deficits due to a brain tumour, a glioblastoma multiforme and two meningiomas respectively. A fourth patient, an 84-year-old man, had a transient ischaemic attack (TIA) with a meningioma as an incidental finding. The first woman had normal CT findings, but MRI revealed the neoplasm. Symptoms included motor loss, sensory disturbances, dysphasia and dysarthria, lasting from 30 seconds up to 10 minutes. The first two patients had surgery; the first one later died when the tumour recurred. The other two patients still exhibit a spontaneous recovery. Of all patients with a clinical presentation of a TIA, 0.4-1% harbour a brain tumour. Clinical symptoms do not distinguish 'transient tumour attacks' from TIAs with a primarily vascular origin. Transient tumour attacks are mainly seen with meningiomas, and to a lesser extent with high-grade gliomas. Changes in intracranial pressure leading to focal ischaemia may explain the occurrence of this phenomenon. A part from intracerebral tumours, non-vascular entities mimicking TIAs can also be seen with demyelinating processes, metabolic disturbances, epilepsy or migraine. Brain imaging is always required in patients with transient neurological deficits. A CT scan may provide false-negative results and in case of doubt, MRI is the preferred diagnostic tool.

Abstract
We report on a patient with recovery of activity of the left orbicularis oris and nasalis muscles 3 months after a complete left facial palsy. Stimulation of the affected facial nerve evoked no responses, whereas contralateral facial nerve stimulation showed polyphasic responses with very long latencies in the nasalis and orbicularis oris muscles. Needle electromyography (EMG) revealed abnormal spontaneous activity in the left orbicularis oris muscle. The motor unit action potentials on the left side of the face could be recruited only during marked contraction of the corresponding muscles on the right and were of low voltage and polyphasic ("nascent potentials"). Contralateral reinnervation is probably due to sprouting of terminal branches crossing the midline of the face and innervating bundles of muscle fibers on the affected side. This phenomenon seems unfamiliar to most clinicians. Whether the activity is due to conduction along nerve fibers or muscle fibers crossing the midline is discussed.

Abstract
Angiogenesis is of vital importance for the growth of solid tumors and constitutes a target for anti-cancer therapy. Glioblastomas (GBMs) are histologically characterized by striking microvascular proliferation. The identification of the mechanism of angiogenesis is of major importance for the further development of anti-angiogenic therapy. Tumor angiogenesis might be the result of a combination of local tissue conditions (especially hypoxia) and specific genetic alterations acquired during oncogenesis. In order to investigate the relationship between genetic aberrations and tumor angiogenesis in GBM xenograft lines, the genetic alterations were examined by Comparative Genomic Hybridization (CGH). Two vascular phenotypes of GBM xenografts could be identified: a well vascularized and a poorly vascularized type. In this model, the poorly vascularized type had a larger number of genetic alterations. However, there was no unequivocal correlation between angiogenesis, growth rate and patterns of genetic alterations as detected by CGH.

Abstract
Medulloblastomas are highly malignant primitive neuroectodermal tumors of the cerebellum that display a wide variety of histopathological patterns. However, these patterns do not provide an accurate prediction of clinical-biological behavior and no satisfactory morphological grading system has ever been presented. Genetic alterations may provide additional diagnostic information and allow clinically relevant subgrouping of primitive neuroectodermal tumors. We examined 10 medulloblastomas and one medulloblastoma cell line. One amplification site on chromosome 8q24 was detected in the cell line corresponding to the known amplification of the c-myc gene in this cell line. The gain of 2p21-24 in two tumors was shown to represent amplification of the N-myc gene by Southern blot hybridization and fluorescence in situ hybridization. The data show that the isochromosome 17 can be recognized using comparative genomic hybridization (CGH) by the typical combination of loss of 17p combined with gain of 17q. No specific pattern of genetic alterations could be linked to the clinical behavior of the tumors. We have compared our results with previous CGH studies on medulloblastomas.

Abstract
OBJECT Human tumors implanted as subcutaneous xenografts in nude mice are widely used for the study of tumor biology and therapy. Validation of these models requires knowledge of the genetic makeup of the xenografts. The aim of this study was to establish whether chromosomal imbalances in 11 xenograft lines derived from human glioblastomas multiforme (x-GBMs) are similar to those found in GBM biopsy samples. The authors also studied genetic stability during serial passaging of three xenograft lines. METHODS Chromosomal imbalances in x-GBMs were detected using comparative genomic hybridization (CGH). The authors compared the CGH results in x-GBMs with those in the original GBMs (o-GBMs) that were used to establish three of the xenograft lines and with the GBM biopsy results reported in the literature (1-GBMs). In three xenograft lines two different passages were analyzed. CONCLUSIONS The results show that the chromosomal imbalances in x-GBMs are similar to those in o-GBMs and 1-GBMs, indicating that the GBM xenograft lines used were valid models from a genetic point of view. The CGH analysis of two different passages of three xenograft lines indicates that x-GBMs (like 1-GBMs) show intratumoral genetic heterogeneity and do not acquire chromosomal imbalances as a result of serial passaging.

Abstract
We report on an additional fourth case of Prader-Willi (PW)-like phenotype and an interstitial deletion of 6q. Despite sharing clinical characteristics, patients with a PW-like phenotype and a deletion of 6q, have features which distinguish them from Prader-Willi syndrome (PWS) patients. This case emphasizes the need to examine patients with suspected PWS, but who are negative for recognizable deletions of 15q11-q13 or uniparental maternal disomy of chromosome 15, for a deletion of 6q.
