PÉNTEK Márta, GULÁCSI László, RÓZSA Csilla, SIMÓ Magdolna, ILJICSOV Anna, KOMOLY Sámuel, BRODSZKY Valentin

[Background and purpose - Data on disease burden of multiple sclerosis from Eastern-Central Europe are very limited. Our aim was to explore the quality of life, resource utilisation and costs of ambulating patients with multiple sclerosis in Hungary. Methods - Cross-sectional questionnaire survey was performed in two outpatient neurology centres in 2009. Clinical history, health care utilisation in the past 12 months were surveyed, the Expanded Disability Status Scale and the EQ-5D questionnaires were applied. Cost calculation was conducted from the societal perspective. Results - Sixty-eight patients (female 70.6%) aged 38.0 (SD 9.1) with disease duration of 7.8 (SD 6.7) years were involved. Fifty-five (80.9%) had relapsing-remitting form and 52 (76.5%) were taking immunomodulatory drug. The average scores were: Expanded Disability Status Scale 1.9 (SD 1.7), EQ-5D 0.67 (SD 0.28). Mean total cost amounted to 10 902 Euros/patient/year (direct medical 67%, direct nonmedical 13%, indirect costs 20%). Drugs, disability pension and informal care were the highest cost items. Costs of mild (Expanded Disability Status Scale 0-3.5) and moderate (Expanded Disability Status Scale 4.0-6.5) disease were 9 218 and 17 634 Euros/patient/year respectively (p<0.01), that is lower than results from Western European countries. Conclusion - Our study provides current inputs for policy making and contributes to understanding variation of costof- illness of multiple sclerosis in Europe.]

[Aim of the study - To summarize the results gained with awake craniotomies, which were performed in either low grade glioma patients or epilepsy surgical patients whose tumor or epileptogenic zone, was in the vicinity of eloquent, mostly language, cortices. Patient selection and methods - In our retrospective study we selected 16 patients who were operated awake between 1999-2011 at the Neurosurgical Department of MÁV Kórház Budapest, or at the National Institute of Neurosciences in Budapest, or at the Neurosurgical Department of the University of Debrecen in Debrecen. In the presurgical evaluation if it was possible we performed functional magnetic resonance imaging, tractography and detailed neuropsychological testing. At the National Institute of Neurosciences all patients were operated with the aid of MR guided neuronavigation. Results - Anesthesia was carried out without complications in all of the 16 cases. Monitoring of sleep deepness has significantly contributed to the safety of anesthesia during the superficial anesthezied states of the operation. The intraoperative neuropsychological tasks used for testing language were sensitive enough to judge the little disturbances in speech during stimulation. Stimulation evoked seizures could be adequately managed during surgery and did not influence the outcome of the procedures. The use of neuronavigation helped significantly by planning the optimal place for the craniotomy and by intraoperative orientation. Conclusions - Awake craniotomies require well practiced surgical teams, which requires the cooperation of neuro-anesthesiologits, neurosurgeons, neuropsychologist and electrophysiologists. It has two goals, first to reduce the time of surgery to minimize surgical complications, secondly the detailed intraoperative mapping of cognitive and motor functions to avoid any neurological deficit. The intraoperative anatomical data provided by the neuronavigation and the functional data provided by awake intraoperative stimulation of the patient together serve the safety of the patient which is essential in the neurologically minimal invasive neurosurgical approach of the 21st century.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]


[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]
