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.

[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.]

[Relationship between patent foramen ovale and cryptogenic stroke in a retrospective hospital-based study]

BÖJTI Péter Pál, BARTHA Noémi Eszter, MAY Zsolt, BERECZKI Dániel, FÜLÖP Szilvia, SZAKÁCS ZOLTÁN, SZILÁGYI Géza

[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.]

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.

[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. ]

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.

[Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]

NAGY Ildikó, FABÓ Dániel

[Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient’s condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. ]

[Dizziness - vertigo Warning symptoms in vertebrobasilar ischemia - Part I. ]

FAZEKAS András

[Dizziness and vertigo - like headache - are the most common complaints which leads patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]

[Angioneuritic edema in ischaemic stroke patients treated with rt-PA]

LOVÁSZ Rita, SAS Attila, KOLLÁR Tibor, PETERCSÁK Edina, FEKETE István, BILINSZKI Erika, VALIKOVICS Attila

[Data of our 254 patients who were treated with rt-PA between 1st of Jan, 2011 and 31st of Dec, 2014 were processed. We focused on angioneurotic oedema as allergic complication of thrombolysis which caused life threatening respiratory obstruction in two cases. We describe these two patients’ history. Out of 254 patients six (2.3%) suffered angioneurotic edema caused respiratory obstruction in two (0.90%) cases. This occurrence is approximately 1.3-5.1% in literature. Five, out of six patients who suffered from angioneurotic oedema, had been treated with ACE inhibitors or ARB before. The role of ACE inhibitors is known in metabolism of bradykinin cascade. Plasmin which present during thrombolysis, precipitates biochemical mechanisms of this potential life threatening complication. Therefore rt-PA alone can be the cause of angioedema, but it can be more frequent together with ACE inhibitors therapy.]

[The possibilities of invasive radiological therapy of deep venous thrombosis and in vitro experimental examination of therapeutic factors affecting the treatment]

HARMAT Zoltán, JÁRAY Ákos, BATTYÁNY István

[INTRODUCTION - The first part of this paper is an overview on the possibilities of invasive radiology treatment of deep venous thrombosis. In the next part an in vitro experiment is described demonstrating the basics of mechanical and pharmaco-mechanical catheters applied in deep venous thrombosis. MATERIALS AND METHODS - The in vitro haemodinamic model of the iliocaval veins contained a thermostat and an engine responsable for pulsing circulation according to the venous system. We tested the chance of driftage of thrombus in different age according to the state of the collateral system. Thrombectomy was made by mechanical (Simpson-catheter) and pharmaco-mechanical (Pulsespray catheter) ways. The weight of the non-drifted thrombi was measured. RESULTS - All the 16 thrombus were flown while collateral system was closed and none of them were flown while the collateral system was open but the rate of their solubility was different. The efficacy of the thrombus-removal by Simpson catheter was better than by Pulse-spray catheter and fresh thrombus-fragments were more soluble than older ones. CONCLUSION - By this in vitro experiment we opened the way for using mechanical and pharmaco-mechanical catheters in deep venous thrombosis.]

[Non-contrast brain ct based systemic thrombolysis of two wake up ischemic stroke patients in rural settings]

POZSEGOVITS Krisztián, RENCZ László, CSÚSZ Lajos, SZABÓ Géza

[Background and presentation - Conventionally the acute ischemic stroke patients who wake up with symptomes (WUS - wake up stroke) cannot benefit from systemic thrombolysis due to the uncertainty of the exact onset time of the cerebrovascular event. Perfusion brain imaging could be used as patient selection tool but the method is not available in many settings. Simple non-contrast CT scan is easily accessible and reliable as it shows the different stages of the evolving ischemia with high accuracy. Early brain CT scan results of WUS patients have the same characteristics as the ones who are surely within therapeutic window. The intravenous thrombolysis with recombinant tissue plasminogen activator (rTPA) of WUS patients seems to be similarly successful as the ones with known onset time, the treatment does not come with excess complications, higher rate of symptomatic intracranial hemorrhage was not found in previous reports. Purpose - In this report we present two systemic thrombolysis cases of acute ischemic stroke patients who woke up with stroke symptoms. Methods - In 2014 and 2015 we performed systemic thrombolysis for one wake up stroke patients, respectively. Both patients had large vessel occlusion. Indication was based on favourable non-contrast brain CT scan results. Results - Treatment of these two patients with rTPA proved to be safe, no hemorrhage occurred after treatment. Conclusion - We presented two acute ischemic stroke patients with symptomes at early wake up who were treated intravenously with recombinant tissue plasminogen activator based on non-contrast CT alone without complications and some moderate improvement at 90 days in the settings of a rural town hospital in a middle income country.]
