Atrial myxoma is a rare cause of stroke. In this report we present the case of a 52-year-old female patient who went to hospital suffering from a headache. Her neurological examination was normal except for a positive Babinski sign on the left. In the superolateral of the right, a Sylvian fissure consistent with a thrombosed aneurysm was detected using computerised tomography (CT). Diffusion MRI showed an acute infarction on the right MCA area. Transthorasic Echocardiography and ECG were normal. A -16×4 mm-sized fusiform perpendicular aneurysm on the M2 segment Sylvian curve of right MCA and a -6×4 mm-sized dissecting aneurysm on P3 segment of the left posterior cerebral artery (PCA) were observed in cerebral angiography. Transesophageal echocardiography (TEE) demonsrated a large mass with a suspected size of 2×2×1.5 cm on the left atrium. The mass was resected and on the eighth day after the operation, she had a temporary vision loss and hyperintensity on the T1 sequence was interpreted as laminary necrosis suspected on Cranial MRI. In follow up, she was stable with 300mg acetylsalicylic acid treatment. The main treatment is surgical resection in stroke caused by atrial myxoma.

[MRI has a significant role in the diagnosis of multiple sclerosis. The newer and newer treatment options of the disease make it necessary to monitor the effectiveness of the therapy. Besides the clinical signs (clinical relapses and progression), the different MRI parameters can also reflect the disease activity. In our current article we summarize those MRI markers, which best predict the long-term disability, based on the international standards.]

[The paraclinical examinations, principally the MRI have an increasing significance in the diagnosis of multiple sclerosis. However, MRI markers also have a prominent role in monitoring of the disease-course and activity, and also in the planning of possible therapeutic changes. In accordance with previously published international guidelines, in this article we propose a protocol for the monitoring the treatment efficacy in multiple sclerosis. This could be the basis of a consensus based guideline to be implemented in Hungary.]

[Nusinersen in the treatment of spinal muscular atrophy]

SINKÓ Gabriella, KISS Zsuzsanna, BERNADETTE Kalman

[Until recently, the diagnosis of spinal muscular atrophy (SMA) has been associated with severe life-long motor disability in adults and with early death in infants. The new experimental therapeutic approaches of the last few years have become more and more promising, while nusinersen was approved for the treatment of SMA in December 2016 in the USA, and in May 2017 in Hungary. Our paper presents mechanisms and clinical benefits of this new medication, and highlights some of the other therapeutic strategies still in experimental stages.]

Introduction - Glioblastoma multiforme (GBM) is the most common malignant primary anomaly of central nervous system. The GBM infiltrates the nearly sturctures from the initial tumor and its metastatic attribution is well known. The aim of our single-centered retrospective study was to introduce the importance of postoperative medical imaging confirmation of total tumor resection for patient with GBM combined concomitant and adjuvant chemoradiotherapy on a 10 year long patient follow up. Methods - From January 2006 to April 2015 we registered 59 patients with newly diagnosed GBM at the University of Kaposvár Health Center Institute of Diagnostic Imaging and Radiation Oncology. The histological diagnosis was confirmed by a proficient neuropathologist (World Health Organisation WHO; grade IV astrocytoma). According to histological status if the ECOG performance status of patients allowed it the mutidisciplinary oncoteam recommended adjuvant chemoradiotherapy all features strictly by Stupp protocol. (60 Gy dose on the gross tumor volume and 2-3 cm margin for the clinical target volume with parallel 75 mg/m2 TMZ. Four weeks after monotherapial phase patients had to recieve 6 cycles of TMZ first cycle with 150 mg/m2 up to 200 mg/m2). The irradiation was carried out by a conformal three dimensional planning system. Results - 59 patients with the median age of 63 (range 17-84) year. Our sample counted 34 male patients and 25 woman patients. 14 patients underwent gross total tumor resection while, 39 patients underwent partial resection and the rest from our sample 6 patients passed through biopsy. Statistical analysis showed a lengthier survival among males than females, with a median survival of 13 months for males and females, the OS of 26.209 for males, meanwhile 15.625 for females. However, the difference is not considerable (log-rank p=0.203). Our study found that the estimated survival of patients at least 50 years old is significantly shorter at a median survival of 12 months (log rank p=0.027) than that of patients below 50 years of age at a median survival of 23 months. The longest estimated median survival was calculated with patients of ECOG '0' condition (16 months). However, no significant difference was found in the estimated survival of patients of different ECOG conditions (log-rank p=0.146). Based on the extent of surgery, complete resection resulted in the longest average survival of 36.4 months, followed by 21.5 months among patients with biopsy, and 15.8 months among patients with partial resection. Different surgical procedures, however, did not result in significant differences in survival (log-rank p=0.059). The overal survival of patients who had complete resection confirmed by MRI compared with the overal survival of patients with residual tumor confirmed by MRI as well we can estimate that there is significant difference between these two groups (p=0,004). Conclusion - Despite complex and intense treatment, recurrence is inevitable and causes relatively rapid death. In our analysis complete resection, as defined from the neurosurgeon’s report and postoperative MRI, resulted in an independently significant improvement in OS. Our results are the evidences that the treatment of patients with glioblastoma multiforme in Hungary is at least on the same level as any other developed European countries.

[Changes of cognitive functions in healthy aging]


[Introduction - Mental health has crucial role in our life. Cognitive changes or decline can lead to many difficulties in daily routine of older people (e.g. organization of daily activities), which can, consequently, influence their well-being. Therefore it is an important question, which cognitive abilities are affected by age-related decline. Methods - In our study we aimed to investigate the changes of cognitive abilities in healthy older adults between 61 and 85 years of age compared to the performance of younger adults. Digit span, counting span, listening span, letter fluency, semantic fluency and action fluency tests were used to assess cognitive abilities, namely working memory and executive functions. Results - The results showed that younger adults performed significantly better in all tests than older adults. Importantly, the performance of older adults was better on tests requiring less complex mental computations (e.g. digit span test) than on more complex tests where both storing and mani-pulating information was required (e.g., counting span test). We also showed that within the older age group, cognitive functions’ decline was linearly associated with increasing age. Conclusion - The present study used several, well-established neuropsychological tests to map the changes of working memory and executive functions in healthy older adults between 61 and 85 years of age compared to younger adults. Our findings can contribute to the development of prevention programs aimed at improving the quality of life of older adults and preventing age-related cognitive decline.]

[The connection between the socioeconomic status and stroke in Budapest]


[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]


[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

The applications of transcranial Doppler in ischemic stroke


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.

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Hypertension and it’s therapy in acut phase of stroke]


[The elevation of blood pressure above normal and premorbid values within the first 24 hours of symptom onset in patients with stroke is relatively common. This acute hypertensive response is usually managed by different group of physicians, including general practitioners, emergency physicians, neurologists, internists, intensivisists. Management strategies of this phenomenon vary considerably. The first consideration in blood pressure management in this clinical setting is to determine whether the patient might be a candidate for thrombolytic therapy. For those patients are not entitled to that therapy premorbide blood pressure values and the type of stroke are the key data for sufficient control of hypertension. In patients with chronic hypertension, the lower end of the autoregulation curve is shifted toward high pressure and an impaired autoregulation due to acute stroke may increase the risk for further brain tissue damage if the blood pressure is inadequately controlled. The current guidelines recommend lowering blood pressure in patients with an intracranial haemorrhage below 160- 180/100-105 mmHg, if the patient is normotensive, while the target level is 180/105 mmHg in hipertensive patients. However, in ischaemic stroke no treatment is recommended if systolic blood pressure <220 mmHg and/or diastolic blood pressure <120 mmHg in the acute stage. Clinical studies are rare which assess the effectiveness of different antihipertensive drugs in acute stroke. The first strong evidence came from the ACCESS (The Acute Candesartan Cilexetil Therapy in Stroke Survivors) trial which suggested that a 7-day course of candesartan after an acute ischaemic stroke significantly improves cardiovascular morbidity and mortality.]
