Background - Acute mortality rate of stroke in Hungary is significantly higher than in Western Europe, which is likely to be partially attributable to suboptimal treatment. Subjects and methods - We examined the use of acute vascular imaging and mechanical thrombectomy for acute ischaemic stroke patients. We collected data on 20 consecutive patients from Hungarian stroke centres before 31st August 2016. Results - Out of the reported 410 patients, 166 (40.4%) underwent CT angiography and 44 (10.7%) had mechanical thrombectomy. Conclusion - Only about 1/3 of acute ischaemic stroke patients eligible for thrombectomy actually had it. The underlying reasons include long onset-to-door time, low utilization of acute vessel imaging and a limited neuro­intervention capacity needing improvement.

[Tracing trace elements in mental functions]

JANKA Zoltán

[Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de­mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area. ]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

A clinical study of an online educational programme for chronic pain patients

GALAMBOS Wellingerné Krisztina, SZOK Délia, CSABAI Márta

Background - The research of alexithymia - the inability to express or understand emotions - has recently become of great importance in clinical practice, mainly in the field of doctor-patient and psychologist patient communication. Many studies have proven the correlation between alexithymia and the development of functional somatic symptoms, i.e. somatization. Purpose - The aim of this clinical study was to examine the emotion-recognition and emotion communication patterns of patients suffering from chronic pain (e.g., headache, low back pain, arthralgia, neuropathy). Moreover, the participants received access to the Hungarian adaptation of a new international online educational site (www.retrainpain.org) dealing with pain management. Methods - Data were collected from the Headache and Chronic Pain Outpatient Clinic, Department of Neurology, Faculty of Medicine, University of Szeged, Hungary (tertiary care - Group 1) and from a general practice in district 2, Budapest, Hungary (primary care - Group 2) from March, 2017 to April, 2018. Patients received a test package containing a pain-specific questionnaire, then the Difficulties in Emotion Regulation Scale (DERS), the Toronto Alexithymia Scale (TAS-20), and the shortened Hungarian version of the WHO-Well-being (WBI-5) had to be completed. After filling out the questionnaires, all patients got access to the Hungarian adaptation of the www.retrainpain.org website. Results - Altogether 92 patients participated in the study (Group 1 n=50; Group 2 n=42). Based on the TAS-20 re­sults, 35 patients reached a pathological score (≥60 points), which indicates the diagnosis of alexithymia. The mean TAS-score was lower in Group 2 (primary care) than in Group 1 (tertiary care) (p=0.003). The DERS disclosed pathological results in 19 cases (p=0.009). As regards the www.retrainpain.org chapters, we received feedback only from 25 out of 92 patients (27%) (Group 1 n=20; Group 2 n=5). Conclusions - Although the examined patients have been suffering from different chronic pain syndromes for years and 50% of them confirmed that symptoms placed at least moderate or heavy burden on their everyday life, the available educational programme was studied only by a smaller proportion of patients than expected. Additionally, those who surveyed the Hungarian adaptation of the www.retrainpain.org website were mainly patients from primary care (Group 2), in spite of the fact that patients from specialized medical care (Group 1) had worse subjective conditions. Our future objective is to extend our database with follow-up results and to improve patients’ response willingness.

[Early experience with CyberKnife treatment in case of intra-, suprasellar hypernephroma metastasis]

SIPOS László, BAJCSAY András, KONTRA Gábor, CZIRJÁK Sándor, JÁNVÁRY Levente, FEDORCSÁK Imre, POLGÁR Csaba

[Among tumours found in the suprasellar region metastases are very rare and the most frequent primary tumours are lung and breast cancer. Data of a patient with clear cell renal carcinoma with intra-suprasellar metastasis will be discussed. As in most of the tumours in the sellar region, the first symptom was visual deterioration with visual field defect. A transsphenoidal debulking of the tumour was performed and the residual tumor was treated by CyberKnife hypofractionated stereotactic radiotherapy. Both our patient’s visual acuity and visual field impairment improved after the surgery and CyberKnife treatment. At 6-month after irradiation, MR of the sella showed a complete remission of the tumour. This was the first treatment with CyberKnife in our country in case of a tumour close to the optic chiasm. According to our best knowledge, there are 21 cases in the literature with renal cell carcinoma metastasis in the suprasellar region.]

[The applicability of 123I-FP-CIT SPECT dopamine transporter imaging in clinical practice]

PERLAKI Gábor, SZEKERES Sarolta, JANSZKY József, DEZSŐ Dániel, ASCHERMANN Zsuzsanna, ZÁMBÓ Katalin, KOVÁCS Norbert

[The 123I-FP-CIT dopamine transporter SPECT imaging is a sensitive method to assess functional dopaminergic neuron terminals in the striatum. The method has also been available in Hungary for years. There are two main indications: (i) to help differentiate essential tremor from clinically uncertain Parkinsonism, including patients with early symptoms and (ii) to help differentiate dementia with Lewy bodies from Alzheimer’s disease. The aim of this paper is to review 123I-FP-CIT SPECT imaging based on international data/guidelines and our own experiences, thereby assisting nuclear medicine practitioners and neurologists.]

[Blood pressure management for stroke prevention and in the acute stroke. The new guideline of European Society of Hypertension (ESH, 2018), European Society of Cardiology and Hungarian Society of Hypertension (HSH, 2018)]

JENEI Zoltán

[Hypertension is the leading modifiable risk factor for stroke. Its prevalence amongst stroke patient is about 60-70% and the benefit of blood pressure (BP) lowering therapy on stroke risk reduction is well established. However the optimal BP targets for preventing stroke and reducing stroke consequences have been controversial. The new European (ESC/ESH) and Hungarian (HSH) hypertension guideline published in 2018 highlighted the primary and secondary prevention of stroke and the BP management in the acute stroke care as well. According results from ACCORD, SPRINT, HOPE-3, and other metaanalysis the systolic blood pressure (SBP) lowering < 120 mmHg has not favourable effect, thus in hypertensive patients < 65 years the SBP should be lowered to a BP range of 120-129 mmHg. In older patients ≥ 65 years the SBP should be targeted to a BP range of 130-139 mmHg (IA). In patients with acute intracerebral haemorrhage careful acute BP lowering with iv. therapy, to <180 mmHg should be considered only in case of SBP ≥ 220 mmHg (IIaB). In patients with acute ischaemic stroke who are eligible for iv. thrombolysis, BP should be carefully lowered and maintained to < 180/105 mmHg for at least the first 24 h after thrombolysis (IIaB). If the patient is not eli gible for lysis and BP ≤ 220/110 mmHg, routine BP lowering drug therapy is not recommended inside 48-72 h (IA). In patients with markedly elevated BP > 220/110 mmHg who do not receive fibrinolysis, drug therapy may be considered, based on clinical judgement, to reduce BP by 15% during the first 24 h after the stroke onset (IIbC). After 72 h of acute stroke in case of hypertensive patients < 65 years the SBP should be lowered to a BP range of 120-129 mmHg (IIaB). In older patients ≥ 65 years the SBP should be targeted to a BP range of 130-139 mmHg (IA). If BP < 140/90 mmHg after stroke, the BP lowering should be considered (IIbA). It is recommended to initiate an antihypertensive treatment with combination, preferably single pill combination of renin-angiotensin system blockers plus a calcium channel blocker and/or a thiazide like diuretics (IA). Lowering SBP < 120 mmHg is not recommended due to advers events regardless of age and type of stroke either in primary or secondary stroke prevention.]

[Dissections of the supraaortic arteries]

CSEH Tamás, SZUKITS Sándor, SZAPÁRY László

[Dissection of the cervical and intracranial vasculature is a rare but important cause of ischaemic stroke especially in young adults. In the majority of cases it affects the extracranial vessels, mostly the internal carotid artery. It might be categorized as spontaneous or traumatic, causing diverse clinical symptoms. Dissection might lead to ipsilateral stroke mainly by artery-to-artery embolisation. Due to its relative rarity compared to the classic ischaemic stroke of the elderly, there are much less clinically relevant information for the clinician to rely on. Several large, randomised, multicentered, prospective studies and some smaller, retrospective analyses have been published recently concerning the genetic background, epidemiology, acute care and secondary prevention of supraaortic arterial dissection which helps the neurologist to provide evidence-based care for his patient. Our aim is to give a short, up-to-date overview of arterial dissections with two case reports.]

[Apoptosis in focal brain ischaemia]

ZÁDOR Zsolt, LACZA Zsombor, BENYÓ Zoltán, HARKÁNY Tibor, HORTOBÁGYI Tibor

[Ischaemic stroke is one of the major causes of death and disability in the developed world. It is caused by focal impairment of cerebral blood flow. The subsequent ischaemic cell death is predominantly necrotic in nature. However, a therapeutically important characteristic is the delayed apoptotic cell demise in the border zone of the primary lesion core. Apoptosis is one of the most intensively studied field of current medical and biological research. The better understanding of its mechanism may provide novel and more effective ways of therapy in a wide range of diseases including ischemic stroke. The salient neurological features of focal brain ischaemia and the morphological signs of apoptotic and necrotic cell death are summarized. The mechanism of apoptosis is discussed. It is divided into an early genetic phase of decisionmaking followed by a cellular execution phase. The characteristics of the early shift in the finely tuned balance of proand antiapoptotic genes and their protein products, which is preceded by an inbalance in intracellular ionized calcium homeostasis, energy depletion and mitochondrial dysfunction is discussed. The crucial role of caspases in apoptosis is emphasized. The three possible pathways during the execution phase is described: the intrinsic- and extrinsic caspase activation cascade and the caspase-independent intracellular signal transduction route. The molecular mechanism of neural cell membrane damage in the execution phase is discussed and some examples of altered protein synthesis also known as message-selection are given. The important role of late reperfusion in the execution phase is emphasized. The possible targets of antiapoptotic therapeutic approaches and the results of experimental studies are presented as well as the perspectives of their use in human clinical care.]

[Objective - In neurology the objective evaluation of improvement of paresis on every-day practice. The aim of this study was to develope and test a small 3-d acceleration measuring device and validate its usefulness. Patients and methods - We collected data from 17 mild and medium severity hemiparetic, bedridden acute ischaemic and hemorrhagic stroke patients and compared with data of 22 control subjects. The devices were attached to the paretic and non-paretic extremities and any movements (m/s2) and movement-durations were registered (24h). The data of movement-monitors were compared also with the changes of National Institute of Health Stroke Scale and European Stroke Scale. The electromiograph-sensor of polysomnograph has been used for validation. Results - Mild differences could be found in the use of dominant and non-dominant upper extremities of control persons. The control persons used their upper extremities more frequently than the stroke patients. Our data showed significant correlation with National Institute of Health Stroke Scale. Higher values on the scores were accompanied with less intensive use of extremities. We found a correlation between the consiousness level of patients and their activity of upper extremities. If the patients had severe consiousness disturbances they used significantly less their upper extremities. Conclusion - Our device sensitively detected the movement-differences between paretic and non-paretic extremities and can be used for quantitative evaluation of patient's neurological and consciousness status.]

[Comparative analysis of attitudes during stroke among risk-exposed gypsy and caucasian hungarian population]

SÁNTHA Emese, PAPP László

[Aim of the study: The authors’s aim was to examine causasian and gypsy hungarians attitude towards illness and their knowledge about stroke. Further aim was to study whether the social and financial status and scholastic qualification have an impact on attitude during illness. Sample and methods: A self-made questionnaire was used for data collection. The authors asked 53 gypsy hungarians with a response rate of 85% (45 in total) and 50 causasian hungarians (response rate: 100%, 50 in total). Results: The gypsy persons have less knowledge about stroke than hungarians. The gypsys’ sociodemographic indicators are significantly worse than the other study group. Bad financial conditions and low employment rate seem to sustain the aversive attitude towards illness. Conclusions: If the non-desirable attitude is sustained by low qualification, employment rate and bad financial conditions, then the settlement of these areas could have an effect on the persons’ health. This study expands previous results, since it shows that the attitude towards illness is not only influenced by the knowledge about health and sickness, but also by the level of education. ]
