[Objective - After routine workup, 23-25% of ischemic strokes etiology remains unknown, i.e. cryptogenic. However, according to international results pathogenic patent foramen ovale (PFO) reveals in 25% of these cases. Aim of our retrospective study to prove the substantial etiological role of PFO-related stroke (PFO-RS) in cryptogenic strokes (CS), and to identify age related differences in stroke etiology. Methods - All new ischemic strokes of 2014-2015 were classified by ASCOD (Atherosclerosis, Small-vessel disease, Cardiac pathology, Other, Dissection) phenotyping. CS was defined when the etiology was unknown. With the help of special ultrasound techniques and RoPE (Risk of Paradoxical Embolism) score the portion of PFO-RS were determined in the examined CS population. Moreover, etiological distribution and differences between age groups (<40, 40-60, >60 years) were described. Results - During the examined period, 8.12% of 985 new ischemic strokes were categorized as CS. 41.38% of examined CS were found to be PFO-related. PFO-RS were considerably more frequent in the younger age groups than in the older age groups. The probability of appearance of PFO-RS were significantly higher in younger age than in case of age independency. Our results verify the substantial etiological role of PFO-RS in CS, and confirm the essential role of contrast enhanced functional transcranial Doppler in the routine diagnostic workup. Age related differences in stroke etiology were found to be statistically significant (p=0.000, df=14), in which small-vessel disease, cardiac pathology, dissection, other pathologies, CS and PFO-RS were contributed significantly. Based on our results, till in young age rare etiologies are typical, while in older age classical etiologies are mainly characteristic.]

[Pharmacological and nonpharmacological treatment of insomnias with regard to sleep medicine]

FALUDI Béla, ROZGONYI Renáta

[Insomnia - one of the most prevalent sleep complain - has a great impact on the everyday life. Basically two different form of insomnia can be defined: the insomnia disorder and the co-morbid insomnias. To treat adequately determination of background pathology is essential, which is based on the help of Sleep Medicine Centers. According to the newest guidelines, the treatment of insomnia disorder is based on cognitive behavioural therapies followed by pharmaceutical intervention. In this review we provide the short description of cognitive behavioural therapies and basic principles of hypnotic drugs. Despite the availability of insomnia guidelines the huge variation of the insomnia medication can be seen in the daily practice. Due to the above mentioned reasons we summarize the good clinical practice of hypnotic drug administration for insomnia patients.]

Evaluation of ischemic stroke patients with systemic cancer

UFUK Emre, TASKIN Gunes, IREM Pinar, FURUZAN Kokturk, ESENGUL Liman, ORHAN Yağiz

Purpose - In cancer patients, an ischemic stroke can be seen as both a direct effect of cancer and a complication of treatment. This condition can negatively affect the follow-up and treatment of these patients. For this research, we aimed to evaluate the clinical features, stroke types and etiological features of ischemic stroke patients with histories of cancer or found to have cancer during the aetiological investigation. Materials and methods - We retrospectively evaluated 100 patients (57 males, 43 females) who were hospitalized with acute stroke and determined to have the presence of cancer or a cancer history during the aetiological investigation between 2011 and 2016. All the demographic features, stroke types and localizations, National Institutes of Health Stroke Scale (NIHSS) scores, Rankin Scale scores, durations of cancer and cancer treatments were recorded. Results - The mean age of the patients was 67.07 ± 10.9 years old, the median NIHSS score was 5, and the median Rankin Scale score was 4. While 79% of patients had ischemic stroke risk factors, 21% did not. Atherosclerotic stroke was the most common stroke type (49%, n=49) and cryptogenic strokes were detected in 21% (n=21). In addition, 63% of the patients had chronic cancer (later than 6 months), 31% of the patients had recent cancer histories (less than 6 months), and 29% of the patients had metastases. Among all the malignancies, lung cancer (n=23), gastrointestinal cancer (n=20) and gynaecological-breast cancer (n=16) were the three most common. Moreover, 37% of the patients underwent chemotherapy, 29% underwent radiotherapy, and 88% of the patients had Carotid/Vertebral Doppler USG abnormalities. Conclusion - Similar to what is stated in the literature, an atherosclerotic stroke was the most common type of stroke in the cancer patients. Stroke risk factors were not detected in 21% of the patients, and in the majority of the patients, atherosclerotic changes in the carotid artery were observed in the Doppler examinations. In the aetiology and prognosis of ischemic stroke, it is important to keep in mind the existence of cancer in addition to the classical stroke risk factors.

Retrospective comparison of efficacy of levetiracetam and lacosamide add-on treatments in patients with partial onset seizure

ACAR Türkan, ARAS Guzey Yesim

Objective - The study aims to retrospectively compare the efficacy of lacosamide (LCS) and levetiracetam (LEV) in add-on treatment in patients with partial-onset epilepsy. Material and method - Patients who have been followed-up for at least one year due to diagnosis of partial epilepsy between September 2014 and December 2017 and who had no seizure control, despite using at least two antiepileptic monotherapies, and therefore undergone LEV or LCS add-on treatment were retrospectively reviewed. Of the patients, total number of seizures and seizure control rates 6 months before and 3 and 6 months after the add-on treatment were compared. Results - There was no statistically significant difference between the 30 patients in the LEV group (12 females, 18 males, mean age 29.7±6.6) and 28 patients in the LCS group (12 females, 16 males, mean age 28.2±6.4) in terms of age, gender and the duration of illness. When the LEV and LCS groups were evaluated separately, the mean number of seizures within 3 and 6 months after the add- on treatment were significantly lower than the mean number of seizures in the last 6 months before the add-on treatment (p<0.005 and p<0.005 respectively). There was no statistically significant difference between the two groups when compared with each other in terms of the rate of decrease in number of seizures and seizure control before and after the add-on treatment (p=0.445 and p=0.238, respectively). Conclusion - LCS appears to be as effective as the currently well-established LEV in the treatment of partial onset seizures. No comparative study was found in the literature similar to this subject matter. There is a need for prospective studies for the comparison of the efficacies of these two drugs.

Is stroke indeed a “Monday morning disease”?

FOLYOVICH András, BÉRES-MOLNÁR K Anna, GIMESI-ORSZÁGH Judit, KATONA Lajos, BICZÓ Dávid, VÖRÖS Károly, GŐBL Gábor, AJTAY András, BERECZKI Dániel

Introduction - The therapeutic time window of acute stroke is short. Decision on the use of intravenous thrombolysis is based on well-defined criteria. Any delay in the transport to a designated stroke centre decreases the odds of therapeutic success. In Hungary, the admission rate of stroke patients peaks on Monday, the number gradually decreasing by the end of the week. This phenomenon has long been suggested to be due to the lack of emergency care approach. According to the literature, however, returning to work following a holiday is a risk factor for acute stroke. A similar phenomenon is well-known in veterinary medicine, a condition in horses referred to as ‘Monday morning disease’. In our study, we analysed the distribution of admissions due to acute stroke by the day of the week in 4 independent data sources. Patients and methods - The number of patients admitted to the Szent János Hospital, Budapest, Hungary with stroke and that of emergency ambulance transports in the whole city of Budapest due to acute stroke were analysed in the period between January 1 and March 31, 2009. The distribution of thrombolytic interventions reflecting hospitalizations for hyperacute stroke was analysed based on data of the Szent János Hospital in 2009-2012, and on national data from 2006-2012. Descriptive statistics was used to present the data. The variation between daily admission was compared by chi-square test. Results - The proportion of daily admission of stroke patients admitted to the Szent János Hospital was the highest at the beginning of the week (18% on Monday, and 21% on Tuesday) and the lowest on the weekend (9% and 9% on Saturday and Sunday, respectively). The distribution of ambulance transports in Budapest due to acute stroke tended to be similar (15% and 15% on Monday and Tuesday, whereas 13% and 12% on Saturday and Sunday, respectively) on different days of the week. No such Monday peak could be observed in a single centre regarding thrombolytic interventions: 18% and 19% of the total of 80 thrombolytic interventions in the Szent János Hospital were performed on Monday and Sunday, respectively. At the national level the higher Monday rate is obvious: during a 7-year period 16.0%, 12.7%, and 13.5% of all thrombolytic interventions in Hungary were performed on Monday, Saturday and Sunday, respectively. Conclusion - Monday preference of stroke is not exclusively caused by the lack of emergency care approach, and the phenomenon is not consistent at the individual hospital level in cases undergoing thrombolysis.

[Assessment of health related quality of life among epileptic patients in the context of coping strategies and subjective disease perception]

KOVÁTS Daniella, CSÁSZÁR-NAGY Noémi, JUHOS Vera, SALLAY Viola, BÉKÉS Judit, FABÓ Dániel, KELEMEN Anna, KURIMAY Tamás

[Purpose – Psychosocial condition and life quality of epileptic patients are greatly determined by the existence of the disease-related comorbid disorders, like depression, anxiety, and the subjective disease perception, as well as the neuropsychological consequences of the seizures. (Whitehead et al. 2015; Goldstein et al. 2005). It has been examined in patients living with epilepsy how subjective disease perception and coping strategies influence life quality, comorbid depression and the condition of anxiety. Methods – Study patients were asked to fill in a self-completion questionnaire, which examined their psychosocial condition (HADS, Beck Depression Scale), life quality (Qolie-31), coping strategies (FKV-LIS), and subjective disease perception (IPQ-R), as well as sociodemographic and disease variables. The subjects of the study: the data of epileptic patients between the age of 18 to 70 was recorded. Patients were selected from the adult outpatients of a national centre, a regional hospital and two private health care centres located in Budapest. Results – Based on the multiple regression analysis. Beck’s depression (b coefficient=-0.351, t=-4.703, p<0.001**). Depressive coping strategy (FKV Dep) (b coefficient = -0.235, t=-3.123, p=0.002**). Subjective health perception (b coefficient =0.232. t=3.643, p<0.001**). Sex (women; b coefficient =-0.162, t=-3.008, p=0.003**). IPQ consequences (b coefficient =-0.161, t=-2.572, p=0.012*). Active coping strategy (FKV Act; b coefficient =0.146, t=2.572, p=0.012*). Type of seizure (b coefficient =-0.138, t=-2.527, p=0.013*), and Sleep quality (b coefficient =-0.125, t=-1.995, p=0.049) explain some 75.6% of the variance of life quality’s total score (model3: F=33.333, p<0.001**. adjusted R2=0.733). Conclusions – Among the factors of the subjective disease perception (IPQ-R), the physical, mental and social consequences play the most important role. Similarly, the impact of negative emotional representation, as well as the erratic nature of the seizures are decisive. Emotional representation, cyclicity and disease coherence have an important role in coping with disease-related negative emotions. ]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[Systemic thrombolysis and endovascular intervention in postpartum stroke]

BERECZKI Dániel Jr., NÉMETH Beatrix, MAY Zsolt, SZAKÁCS ZOLTÁN, GUBUCZ István, SZIKORA István, SZILÁGYI Géza

[Introduction - There are no previously published cases about intravenously applied recombinant tissue plasminogen activator in acute ischemic stroke during puerperium. Case presentation - We report a 40-year-old woman with postpartum acute ischemic stroke caused by multiple cervical artery dissections treated by systemic thrombolysis and endovascular intervention. Discussion - There are only limited data regarding thrombolytic treatment in acute stroke during pregnancy and puerperium. Current acute stroke treatment guidelines - while considering pregnancy as a relative exclusion criterion - do not deal with the postpartum state. Conclusion - As the condition is rare, randomized controlled trials are not feasible, therefore further reports on similar cases could eventually help us suggest guidelines or at least propose recommendations for the acute thrombolytic treatment of strokes occurring in pregnancy and puerperium.]

ORBÁN-KIS Károly, SZŐCS Ildikó, FEKETE Klára, MIHÁLKA László, CSIBA László, BERECZKI Dániel, SZATMÁRI Szabolcs

Objectives – Stroke is the third leading cause of death in the European region. In spite of a decreasing trend, stroke related mortality remains higher in Hungary and Romania when compared to the EU average. This might be due to higher incidence, increased severity or even less effective care. Methods – In this study we used two large, hospital based databases from Targu Mures (Romania) and Debrecen (Hungary) to compare not only the demographic characteristics of stroke patients from these countries but also the risk factors, as well as stroke severity and short term outcome. Results – The gender related distribution of patients was similar to those found in the European Survey, whereas the mean age of patients at stroke onset was similar in the two countries but lower by four years. Although the length of hospital stay was significantly different in the two countries it was still much shorter (about half) than in most reports from western European countries. The overall fatality rate in both databases, regardless of gender was comparable to averages from Europe and other countries. In both countries we found a high number of risk factors, frequently overlapping. The prevalence of risk factors (hypertension, smoking, hyperlipidaemia) was higher than those reported in other countries, which can explain the high ratio of recurring stroke. Discussion – In summary, the comparatively analyzed data from the two large databases showed several similarities, especially regarding the high number of modifiable risk factors, and as such further effort is needed regarding primary prevention.

[Cerebrovascular diseases in patients with chronic kidney disease]

KISS István, NAGY Judit

[The reason of the unfavourable life expectancy of patients with chronic kidney disease (CKD) is not only the development of end-stage renal failure but the frequent appearance of cardiovascular diseases (CVD). Chronic kidney damage itself is a cardiovascular risk state and the occurrence of CVD/associated diseases is significantly higher in chronic kidney failure. Beside risk stratification and valid treatment of CVD (hypertension, diabetes mellitus, ischemic heart disease e.g.) we and the international nephrological community have left the cerebrovascular diseases of CKD patients out of consideration. However, up to 50% of patients suffering a stroke will die immediately, only 10% of stroke survivors can continue his/her profession, but the others will be permanently disabled. High blood pressure is a strong predictor of stroke and of other CVD in most of the patients. In stroke risk reduction it is particularly important to reach the target blood pressure values. The main object of the “Live under 140/90 mmHg” programme of the Hungarian Society of Hypertension is to familiarize with target blood pressure itself and how to reach target blood pressure. In 2010, prevention, early diagnosis and management of stroke are the most important challenges of this programme (The Brain Control Programme). We think it is advisable to prepare and publish a clinical practice guideline in collaboration with stroke societies which is similar to the guidelines of international societies and of the Hungarian Society of Stroke but specific for CKD patients. This guideline would help to give a uniform, up-to-date treatment for the cerebrovascular diseases of CKD patients.]

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.
