[Gliomas constitute more than 50% of brain tumours. Primary malignant forms recur within 1/2 to 1 year after surgery, and even totally removed benign forms may recur. 50% of recurrent astrocytomas are more malignant than the original tumour. The time elapsing until recurrence strongly depends on the degree of malignity and the surgical removal. However, the age of the patient also plays an important role. Survival of the patient after the establishment of diagnosis also depends on the therapy. Effective treatment requires a knowledge of the degree of malignity as well as differentiation between recurrent tumour and radiation necrosis. CT and MRI scans offer high sensitivity, but poor specificity. Evaluation of tumour metabolism by means of 18F-fluoro-deoxy-glucose positron emission tomography (PET-FDG) helps to determine the degree of malignity of the gliomas, and recurrent tumour can safely be differentiated from necrosis following radiation therapy.]

[Symptomps, localization of cerebral lesions and aetiology of "letter-by-letter" reading]

SÉRA László, MÁRKUS Atilla, BERNÁTH László

[The symptoms, localization of cerebral lesions and aetiology were analysed literally data of 78 patients suffering from pure alexia (letter-by-letter reading). During the 100 years since Déjerine's first case study on the issue was been published our knowledge on the clinical and pathomorphological characteristics of pure alexia has become more exact. On the one hand, clinical symptomatology has narrowed, eg. right homonymous hemianopsia is no regarded as a compulsory concomintant symptom on the other hand, the locus of damage underlying the symptoms may be at various areas of the brain (eg. subangular), not only at the occipital regions. The role of the posterior trajectory system in the reading process emphasized. In addition however, taking into account recent neuropsychological findings, the importance of other areas of the brain is presumable. In accordance with cognitive psychological research of the reading process it is concluded that it is essential the is for our understanding of the whole reading process that all of these factors are taken into consideration.]

[Transoral and posterior fixation for inveterated fracture of odontoid process - Case report]


[Combined operative treatment is reported of a fixed malpositioned type III. (according to Anderson-D'Alonso) oblique anterior odontoid process fracture. Due to the ventral and dorsal compression of the spinal canal a part of the dens and a part of the body were transorally removed, and a part of the arch of the atlas also removed by a dorsal approach. The position was fixed by means of a combined method of a transoral Harms-plate and a posterior C.I.-C.II. fransarticular screwing according to Magerl. With this method were achiered proper decompression and stabile C.1.-C.II. arthrodesis.]

[Cerebral aspergillosis]


[Four cases of cerebral aspergillosis are reported. Brain abscesses developed in a patient with chronic alcoholism and pyogenic urogenital process, and in a baby, treated for aplastic anaemia. Haemorrhagic necroses were found in the other two cases, one of them suffered from agressive hepatitis, the other had lymphoid leukaemia. Pulmonary alterations were observed as part of generalised aspergillosis in all the cases. Early diagnosis of pulmonary processes should be emphasized as the disease can hardly be influenced when neurologic symptoms appear.]

[The effect of the cue-controlled modification of the level of vigilance on the intentional inhibition of seizure in patients with partial epilepsy]


[The cue-controlled modification of the level of vigilance, as one of the methods of self-control appeared to be a practicable therapeutic intervention for the intentional inhibition of epileptic seizures in some special cases of epilepsy. The authors worked out a variation of the above self-control technique, in which the aura imagined in hypnosis was associated with the change in vigilance in patients suffering from partial epilepsy, in order to enable them to try to inhibit the epileptic fits with this associated modification of the level of alertness during auras. The authors report two cases of intractable partial epileptic patients, in which the patients attained the application of this self-control method. The first patient carried out intentional seizure inhibition in 73 cases over one year, reducing the frequency of the fits from the previous 115 to 77. In the second case, the patient was able to decrease considerably even the number of epileptic auras by learning and applying the technique, consequently the number of auras decreased to 7 compared with the 38 fits observed in the previous 8 months, further he was able to terminate the attack in 6 cases out of auras. The authors think, that their method might be useful for a certain group of patients suffering from partial epilepsy to inhibit epileptic attacks, and would mean a new possibility in the management of intractable cases.]

[The history of a 23 year old male patient is reported who developed sudden disturbance of consciousness, diplopia, right hemiparesis, dysesthesia and later dementia due to medial thalamic infarction. The coexistence of atrial septal aneurysm and platelet hyperaggregability suggested microembolisation. The importance of the transesophageal echocardiography and platelet function tests in young patients with cerebral ischemia is emphasised.]

[The paraclinical examinations, principally the MRI have an increasing significance in the diagnosis of multiple sclerosis. However, MRI markers also have a prominent role in monitoring of the disease-course and activity, and also in the planning of possible therapeutic changes. In accordance with previously published international guidelines, in this article we propose a protocol for the monitoring the treatment efficacy in multiple sclerosis. This could be the basis of a consensus based guideline to be implemented in Hungary.]

Introduction - Glioblastoma multiforme (GBM) is the most common malignant primary anomaly of central nervous system. The GBM infiltrates the nearly sturctures from the initial tumor and its metastatic attribution is well known. The aim of our single-centered retrospective study was to introduce the importance of postoperative medical imaging confirmation of total tumor resection for patient with GBM combined concomitant and adjuvant chemoradiotherapy on a 10 year long patient follow up. Methods - From January 2006 to April 2015 we registered 59 patients with newly diagnosed GBM at the University of Kaposvár Health Center Institute of Diagnostic Imaging and Radiation Oncology. The histological diagnosis was confirmed by a proficient neuropathologist (World Health Organisation WHO; grade IV astrocytoma). According to histological status if the ECOG performance status of patients allowed it the mutidisciplinary oncoteam recommended adjuvant chemoradiotherapy all features strictly by Stupp protocol. (60 Gy dose on the gross tumor volume and 2-3 cm margin for the clinical target volume with parallel 75 mg/m2 TMZ. Four weeks after monotherapial phase patients had to recieve 6 cycles of TMZ first cycle with 150 mg/m2 up to 200 mg/m2). The irradiation was carried out by a conformal three dimensional planning system. Results - 59 patients with the median age of 63 (range 17-84) year. Our sample counted 34 male patients and 25 woman patients. 14 patients underwent gross total tumor resection while, 39 patients underwent partial resection and the rest from our sample 6 patients passed through biopsy. Statistical analysis showed a lengthier survival among males than females, with a median survival of 13 months for males and females, the OS of 26.209 for males, meanwhile 15.625 for females. However, the difference is not considerable (log-rank p=0.203). Our study found that the estimated survival of patients at least 50 years old is significantly shorter at a median survival of 12 months (log rank p=0.027) than that of patients below 50 years of age at a median survival of 23 months. The longest estimated median survival was calculated with patients of ECOG '0' condition (16 months). However, no significant difference was found in the estimated survival of patients of different ECOG conditions (log-rank p=0.146). Based on the extent of surgery, complete resection resulted in the longest average survival of 36.4 months, followed by 21.5 months among patients with biopsy, and 15.8 months among patients with partial resection. Different surgical procedures, however, did not result in significant differences in survival (log-rank p=0.059). The overal survival of patients who had complete resection confirmed by MRI compared with the overal survival of patients with residual tumor confirmed by MRI as well we can estimate that there is significant difference between these two groups (p=0,004). Conclusion - Despite complex and intense treatment, recurrence is inevitable and causes relatively rapid death. In our analysis complete resection, as defined from the neurosurgeon’s report and postoperative MRI, resulted in an independently significant improvement in OS. Our results are the evidences that the treatment of patients with glioblastoma multiforme in Hungary is at least on the same level as any other developed European countries.

Novel structured MRI reporting system in neonatal hypoxic-ischemic encephalopathy - issues of development and first use experiences


Purpose - To develop an evidence-based, standardized structured reporting (SR) method for brain MRI examinations in neonatal hypoxic-ischemic encephalopathy (HIE) suitable both for clinical and research use. Materials and methods - SR template development was based on comprehensive review of the pertinent literature with the basic sections and subdivisions of the template defined according to MRI sequences (both conventional and diffusion-weighted, MR-spectroscopy (MRS), and T2*-weighted imaging), and the items targeted on age-related imaging patterns of HIE. In order to evaluate the usability of the proposed SR template we compared data obtained from the brain MR image analysis of 87 term and 19 preterm neonates with the literature. The enrolled 106 infants were born between 2013 and 2015, went through therapeutic hypothermia according to the TOBY criteria due to moderate to severe asphyxia and had at least one brain MRI examination within the first two weeks of life. Ethical approval was obtained for this retrospective study. Descriptive statistical analysis was also performed on data exported from the structured reporting system as feasibility test. Results - The mean gestational age of the study population was 38.3±2.2 weeks; brain MRI was performed on 5.8±2.9 day of life, hence in 78% of our patients after the conclusion of therapeutic hypothermia. Our main imaging findings were concordant to the pertinent literature. Moreover, we identified a characteristic temporal evolution of diffusion changes. Interestingly 18% (n=19/106) of the clinically asphyxiated infants had isolated axial-extraaxial haemorrhage without any imaging sign of HIE. Conclusion - In this article our approach of reporting HIE cases with our novel SR template is described. The SR template was found suitable for reporting HIE cases, moreover it uncovered time and location dependent evolution of diffusion abnormalities (and pseudonormalization, as well), suggesting its usefulness in clinical research applications. The high number of isolated intracranial haemorrhages, and the changing diffusion pattern emphasizes the importance of early imaging in HIE.

[MRI has a significant role in the diagnosis of multiple sclerosis. The newer and newer treatment options of the disease make it necessary to monitor the effectiveness of the therapy. Besides the clinical signs (clinical relapses and progression), the different MRI parameters can also reflect the disease activity. In our current article we summarize those MRI markers, which best predict the long-term disability, based on the international standards.]

Wnt pathway markers in low-grade and high-grade gliomas

NAGY Ádám, TOMPA Márton, KRABÓTH Zoltán, GARZULY Ferenc , MARÁCZI Alexandra , KÁLMÁN Bernadette

Aberrant activation of the Wnt pathway contributes to differentiation and maintenance of cancer stem cells underlying gliomagenesis. The aim of our research was to determine as to what degrees some Wnt markers are expressed in gliomas of different grades, lineages and molecular subtypes. Nine grade II, 10 grade III and 72 grade IV surgically removed, formalin-fixed paraffin-embedded glioma specimens were included. Mutation status of IDH1 codon 132 was defined by immunohistochemistry and pyrosequencing in all tumors. Grade II and III astrocytic and oligodendroglial tumors were further tested for the expression of p53 and ATRX by immunohistochemistry, and codeletion of 1p19q by fluorescent in situ hybridization. Expression levels of the non-canonical Wnt5a and Fzd2, and the canonical Wnt3a and beta-catenin Wnt pathway markers were determined by immunohistochemistry, and compared between subgroups stratified according to grade, lineage and the presence or absence of IDH1 R132H/C mutations. In the normal brain – grade II-IV glioma comparisons, a gradual increase was observed for the expressions of Wnt5a, Wnt3a, Fzd2 and beta-catenin. In the astroglial and oligodendroglial lineages of grade II and III gliomas, only the Wnt5a expression was significantly higher in the astroglial subgroup. Stratification according to the IDH1 status resulted in a significant increase of the Wnt3 expression in the wild type grade II-IV gliomas. These data extend previous observations and show a correlation of Wnt pathway activity with glioma grade. Further investigations of the Wnt marker expression regulation according to glioma lineage or IDH gene mutational status are in progress by using more exact molecular approaches.
