[The propagation and semiology of focal epileptic seizures. case presentations to the insula. theoretical considerations]

BALOGH Attila, BALOGH Attila ifj.

[Study objectives – The developing of diagnostical examinations in epileptology provides new challenges in seizure semiology. On the analysis of seizures it is important to examine the mechanisms of their propagation. The brain connectivity (based on the neuroimaging), the shadowing of the movement of excessive neuronal activity (based on computerized EEG and MEG methods), the cognition of the physiological and pathological brain networks are the foot- stone of the epileptic seizure propagation. The investigators prove, by means of case demonstrations of the role of the network nodes and the role of the epileptic hubs in the seizure symptomatology. Methods – The preoperative, intra and postoperative data are analised of three insular and one parietal epileptic patients in point of view of their seizure symptomes. Complex neuroimaging, noninvasive and invasive electrophysiology, intensive long-term video-EEG monitoring, computerized EEG analysis, fuctional mapping, intraoperative corticography were used. The etiology were confirmed with hystology. Results – It is observed that on seizure semiology our patients plays the insula a double role. In some cases, it is the focus of insular seizures with their symptoms difficult to identify. However, in the majority of cases and as a consequence of its rich neural connections, the insula has a peculiar property in the evolution of the symptomatogenic features of seizures. This observations are developing new relationships between the mechanism of seizure propagation and its semiological consequences. Conclusions – On epileptological point of view there are brain structures which has peculiar role in the „designe” of propagation of the epileptic excitement. The numerous new methods in neuroimaging and neurophysiology allowed the connectomical examination of the epileptic networks. The role of the epileptic diathesis is approachable with the metholdology of the brain connectivity. Theoretically the node of the epileptic network consist of the potential pathes where the localised excessive excitement can propagete. The route where the actual seizure can go adhead is determined by the actual edpileptic propensity of the above mentioned potential pathes.]

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis


The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

[The comprehensive screening program of Hun­gary (MAESZ) 2010-2020-2030 is a unique initiative in Hungary and worldwide too. This largest humanitarian program provides by the latest technology free scree­ning tests for all residents in Hungary. The program developed by 76 pro­fessional organizations offers 38 scree­ning tests to every participants free of charge, in a special designed screening truck. Screening program performed by MAESZ includes cardiovascular, ophthalmologic, dermatologic, gynecologic, and neurologic investigations, lab tests, audiometry, blood pressure and arterial stiffness measurements, and venous Doppler ultrasound examinations. More­over, screening tests for lactose intolerance, colon malignancy, inflammatory bowel disease, reflux disease, urine incontinency, prostatic cancer and physical activity level were evaluated. Starting 2020, a dental screening station will be added to the mobile unit for early detection of oral cancers. Beyond screening tests, special attention is paid to assess health threatening risk factors, such as smoking, alcohol con­sumption, physical inactivity, un­healthy nutrition, and obesity. The program demonstrates the key elements of first aid from reanimation to bandage of burns in cooperation with professional and civil organisations. Furthermore, during the waiting time, participants get lifestyle recommendations and a health booklet with a bar code enabling the immediate computer analysis of test outcomes. Since the 2018/2019 school year the official prevention program for children entitled “Travel around the Empire of Health” was started. During its 10 years, the MAESZ performed 7 million free of charge screening tests on 1,886 scenes, enrolled 560,000 participants, invested 16,000 hours for prevention, handed out 1,200,000 health booklets and 391,000 prevention info packages to thousands of fami­lies. More than 20,000 health professionals (GPs, nurses, dietetics, health development agents, public health government officials, Accident Prevention Committee of National Police Headquarters, General Directorate of Social Affairs and Child Protection and non-governmental organizations) have been participated. The program designed to improve social health aims to help more and more Hun­garian citizens to be informed about their health status and to reminds them of the importance of prevention. ]

[Correction of the physiological artefacts at pre-surgical clinical functional MR]

KISS Máté, GÁL Andor Viktor, KOZÁK Lajos Rudolf, MARTOS János, NAGY Zoltán

[Introduction/aim of the study - Pre-surgical functional MRI (fMRI) is an important modality of examinations before brain surgery. There are several artefacts (e.g. motion, susceptibility) which may hinder the evaluation of fMRI data. Physiological artefacts (breathing, pulsation) also affect the sensitivity and specificity of anatomical localization. The aim of this study is to demonstrate the efficiency of physiological artefact identification and removal methods for presurgical evaluation. Materials and methods - Siemens Magnetom Verio 3T MRI scanner was used to collect data. The physiological parameters (breathing, pulse) were recorded with the MRI system’s built-in devices. Data from fourteen patients - with primary brain tumour - were evaluated with SPM12 utilizing the RETROICOR/RVHR tool to detect and decrease the effect of physiological artefacts. We compared the statistical maps obtained with and without the physiological correction using the Jaccard similarity coefficient, and ROI analyses. Results - Significant differences were found in the mean ROI values (p<0.0016) and the extensions of eloquent activations (p<0.0013), when using the physiological correction (RETORICOR/RVHR) based on convolution method. On the other hand, no significant differences were found between the ROIs’ standard deviations (F=0.28). The RETROICOR/ RVHR method helps to define the precise localisation of eloquent areas (p<0.009). The number of irrelevant (non-significant) voxels were increased (p<0.001). Conclusions - Minimising of physiological artefacts in fMRI data calculations, the (RETROICOR/RVHR) method based on convolution has been successfully adapted. This algorithm could be helpful before neurosurgical intervention. The activity pattern became more reliable. ]

[Current questions of multiple sclerosis: the secunder progressive form of the disease]


[Recent data suggest that long-term worsening is common in relapsing-remitting multiple sclerosis patients and is largely independent of relapses or new lesion formation on brain MRI. The current definition of secunder progressive multiple sclerosis is worsening of disability independent of relapses over at least 6-month interval. Early focal inflammatory disease activity and spinal cord lesion are predictors of very-long term disease outcomes in relapse - onset multiple sclerosis. The potential of PET imaging to visualize hidden inflammation in MS brain in vivo is an important contribution for better understanding the progression of the disease. Therefore, PET imaging is a promising tool in detecting the conversion from relapsing remitting multiple sclerosis to secunder progressive form of multiple sclerosis. Furthermore, neuro-axonal damage is the pathological substrate of permanent disability in different neurological disorders including multiple sclerosis. The neurofilament proteins have promise in this context because their levels rise upon neuro-axonal damage not only in the cerebrospinal fluid but also in blood. Patients with increased serum levels of neurofilament at baseline, independent of other clinical and MRI variables, experience significantly more brain and spinal cord volume loss over 2 years and 5 years of follow-up. The kynurenine-pathway abnormalities may be associated with the swich from early-mild stage multiple sclerosis to debilitating progressive forms of the disease. Analysis of these metabolites in serum may have application as multiple sclerosis disease biomarkers. Free radical action has been suggested as a causal factor in the illness. Increased free radical production and consumption of the scavenger molecules were found during the active phase of the disease. Based on the clinical findings (EXPAND Study) and pathomechanism of the disease siponimod is approved by the US Food and Drug Administration for the treatment of relapsing remitting forms of multiple sclerosis, to include secunder progressive multiple sclerosis with active disease, relapsing-remitting multiple sclerosis and clinically isolated syndrome.]

[The Veszprém model, alias a different approach of psychiatric care]


[This study describes an integration of a county-level psychiatric care unit with two elements of primary social care, namely the community psychiatric care and the daycare for psychiatric patients via mediation of a specific foundation. Adequate trainings make the connection and dual employment possible in the presented system. On the health care side development is characterized by extended psychiatric care with effective psychosocial interventions. Adding specialized group psychotherapies and sociotherapies to the activity of the social care also brought a quality change, extension of which provided self-help and the consumers' applicability as therapy leaders in sociotherapy group. Based on our ten years of practice we may declare that recovery-based psychiatric rehabilitation can be realized more effectively in this community-based biopsychosocial model of care. ]

[What does a triage nurse do? ]

BALOGH Khernné Mariann

[Emergency patient care department problems have recently come to the fore, especially in terms of waiting times and triage activity. It is still not entirely clear to society what is the triage system is, what is it good for, and who is the person, who applies the classification of patients. There is countless conflicts and tensions in the process of health services due to lack of knowledge. In Hungary, emergency departments play a prominent role in healthcare. Increased patient flow is a global problem, and therefore a distinction should be made between the „door to physician time” of the patients. The so-called grading system (triage) has been developed for this purpose, during which an experienced qualified nurse will measure and assess the patient’s condition as quickly as possible on the basis of different criteria. In my communication, I present the triage activity, the use of the classification system, what the triage nurse is doing, by comparing two cases. ]

[The importance of brain-derived neurotrophic factor in psychopathology and cardiovascular conditions: psychosomatic connections]


[Cardiovascular diseases and mood disorders are common public health problems worldwide. Their connections are widely studied, and the role of neurotrophins, especially brain derived neurotrophic factor (BDNF) is already supposed in both conditions. However, no reviews are available describing possible associations between cardiovascular risk and mood disorders based on BDNF. Decreased level of BDNF is observed in depression and its connection to hypertension has also been demonstrated with affecting the arterial baroreceptors, reninangiotensin system and endothelial nitric oxide synthase activity. BDNF was also found to be the predictor of cardiovascular outcome in different patient populations. Our aim was to overview the present knowledge in this area demonstrating a new aspect of the associations between mood disorders and cardiovascular diseases through the mediation of BDNF. These findings might enlighten a new psychosomatic connection and suggest a new therapeutic target that is beneficial both in respect of mood disorders and cardiovascular pathology.]
