[MR imaging of acute disseminated encephalomyelitis and multiple sclerosis in children. A review (in English language)]

PATAY Zoltán

[Inflammatory diseases of the central nervous system (CNS) are relatively rare in children, but their relevance to public health is considerable due to frequent and significant long term morbidity and even mortality. As in adults, acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) and their variants are the most common entities in this group of pathologies in the pediatric patient population. Recent efforts have focused on establishing standardized diagnostic criteria schemes to facilitate the diagnosis and differential diagnosis of these diseases, however especially with multiple sclerosis those have not been fully validated yet for disease occurring in children. In recent decades the role of MRI has been constantly increasing in the diagnostic work-up of suspected inflammatory diseases of the CNS as well as in the follow-up of patients with confirmed disease. Currently, MRI is the first-line diagnostic imaging modality in ADEM and MS and is fully integrated in the most widely used diagnostic criteria schemes, but it has a key role in clinical therapeutic research trials as well. This paper provides an update on the current concepts and strategies of MRI in inflammatory diseases of the CNS, as well as a review of the imaging semiology of the various disease entities and variants with emphasis on clinical and imaging particularities relevant to the pediatric patient population.]

[Current issues of neuroimaging diagnostics of multiple sclerosis]

BAJZIK Gábor

[Magnetic resonance imaging techniques have been routinely used in diagnostics and follow-up of multiple sclerosis and magnetic resonance imaging findings are incorporated into the current diagnostic criteria of the disease. International guidelines were created aiming to define the indication, timing, minimum requirements and interpretation of magnetic resonance examination in multiple sclerosis. In Hungary, there is a lack of widely-accepted standardized protocol, therefore presenting the magnetic resonance diagnostic criteria and the international guidelines may prove useful. It may also point towards consideration of a national guideline.]

[Application of diffusion weighted imaging in neuroradiology]

BARSI Péter

[Diffusion weighted magnetic resonance (MR) imaging is available on all modern MR scanners. It depicts the motion of water molecules in the brain tissue and intracranial foreign tissues and provides information on changes in the proportion of intra- and extracellular space and the characteristics of foreign intracranial tissues and fluids. It is of utmost importance eg. in the diagnostics and differential diagnostics of acute ischaemic brain lesions, the diagnostics of inflammatory brain processes and in the differential diagnostics of intracranial space-occupying lesions. The examination method of short scanning and post-processing time must be completed with the apparent diffusion coefficient (ADC) maps and it is indispensable in the everyday neuroradiological diagnostics. Diffusion tensor imaging and tractography are able to depict the white matter tracts. They require a longer scanning and post-processing time and have several technical problems yet to be solved, but they provide help in their current state e.g. in the surgical planning of intracranial space-occupying lesions.]

[State of the art neurointerventional treatment of intracranial vascular anomalies]

SZIKORA István, BERENTEI Zsolt, MAROSFŐI Miklós, KULCSÁR Zsolt, GUBUCZ István

[Haemorrhagic stroke is frequently caused by rupture of intracranial vascular anomalies. The role of minimally invasive therapy in the treatment of such lesions has increased dramatically within the past two decades. The purpose of this study is to summarize the pathology and clinical features of these anomalies and to overview the potential applications of neurointerventional techniques in their treatment. Endovascular therapy is the first choice of treatment for most intracranial aneurysms. Both pial and dural arteriovenous malformations are being treated by endovascular techniques, but the combination of different modalities (such as endovascular, direct surgery and radiosurgery) is frequently applied. Capillary malformations require surgical removal and venous anomalies do not allow for any type of invasive treatment. State of the art therapy of intracranial vascular anomalies require institutions equipped with appropriate imaging facilities and having equal access to both conventional neurosurgical and neurointerventional techniques with ample experience and case load.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

Long-term follow-up results of concomitant chemoradiotherapy followed by adjuvant temozolomide therapy for glioblastoma multiforme patients. The importance of MRI information in survival: Single-center experience

LUKÁCS Gábor, TÓTH Zoltán, SIPOS Dávid, CSIMA Melinda, HADJIEV Janaki, BAJZIK Gábor, CSELIK Zsolt, SEMJÉN Dávid, REPA Imre, KOVÁCS Árpád

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.

[Background and purpose - Data on the disease burden of Duchenne Muscular Dystrophy are scarce in Hungary. The aim of this study was to assess patients’ and their caregivers’ health related quality of life and healthcare utilisations. Methods - A cross sectional survey was performed as part of the European BURQOL-RD project. The EQ-5D-5L and Barthel Index questionnaires were applied, health care utilisations and patients’ informal carers were surveyed. Results - One symptomatic female carer, 50 children (boys 94%) and six adult patients (five males) participated in the study, the latter two subgroups were included in the analysis. The average age was 9.7 (SD=4.6) and 24.3 (SD=9.8) years, respectively. Median age at time of diagnosis was three years. The average EQ-5D score among children and adults was 0.198 (SD=0.417) and 0.244 (SD=0.322), respectively, the Barthel Index was 57.6 (SD=29.9) and 53.0 (SD=36.5). Score of satisfaction with healthcare (10-point Likert-scale) was mean 5.3 (SD=2.1) and 5.3 (SD=2.9). 15 children were hospitalised in the past 12 months for mean 12.9 (SD=24.5) days. Two patients received help from professional carer. 25 children (mean age 11.1, SD=4.4 years) were helped/supervisied by principal informal carer (parent) for mean 90.1 (SD=44.4) hours/week and further family members helped in 21 cases. Correlation between EQ-5D and Barthel Index was strong and significant (0.731; p<0.01) as well as with informal care time (-0.770; p<0.01), but correlation with satisfaction with health care was not significant (EQ-5D: 0.241; Barthel Index: 0.219; informal care: -0.142). Conclusion - Duchenne muscular dystrophy leads to a significant deterioration in the quality of life of patients. Parents play outstanding role in the care of affected children. This study is the first in the Central and Eastern European region that provides quality of life data in this rare disease for further health economic studies.]

[Guidelines for the treatment of traumatic brain injury - 2017]

BÜKI András, BARZÓ Pál, DEMETER Béla, KANIZSAI Péter, EZER Erzsébet, TÓTH Péter, HORVÁTH Péter, VARGA Csaba

[Traumatic brain injury (TBI) is recognized to be the main cause of death and disability in the first four decades representing a major socio-economical problem worldwide. Recent communications revealed a particularly worrying image about the quality of care for TBI in Hungary. For any improvement a systematic approach characterized by utilization of scientific evidence based guidelines forming the basis for close monitoring of the actual care are considered a prerequisite. In Hungary the first evidence based guidelines in the field of TBI have been issued by the National Society for Anesthesiology and Intensive Care more than two decades ago followed by joint guidelines of the Hungarian Neurosurgical Society and the Hungarian College of Neurosurgeons. These publications were primarily based on the work of the European Brain Injury Consortium as well as guidelines issued by the Brain Trauma Foundation. Recent renewal of the latter and a need to refresh the outdated national guidelines was met by a call from regulatory authorities to issue the updated version of the Hungarian TBI-guidelines. The present review is aimed to briefly summarize the most fundamental elements of the national head injury guidelines that would hopefully be officially issued in a far more detailed format soon.]

[Europe’s highest COVID-19 mortality experienced behind the former iron curtain]

RIHMER Zoltán

[While 11 out of the 15 first European countries with highest COVID-19 mortality rates are Post-Socialist countries (73%), and only 9 out of the 31 countries on place 16-46 (29%) are Post-Socialist. All of the top 17 European countries with the highest cumulative excess-mortality since the beginning of the COVID-19 pandemic era, are Post-Socialist countries (100%) as well as 19 out of the top 20 (95%). The dividing line between high and low COVID-19 mortality of European countries follows exactly the path of the former Iron Curtain. In addition, out of the 43 data reporting European countries, all the 18 with the lowest vaccination rate (100%) are Post-Socialist. The main cause of these differences in European COVID-19 mortality may be the traditionally disadvantageous physical and mental condition of the population of Post-Socialist countries, but this problem needs further, more intense investigations.]
