[Our aim was to assess the social insurance costs of hospital treatments for acute stroke in Hungary between 2003 and 2005. We studied how much burden stroke patients impose on the financer (National Health Insurance Fund Administration) in acute and chronic hospital admissions. We extracted the data of “new” stroke patients (ICD-10: I60-64 diagnosis) hospitalized in May 2003 from the database of the financer. We analyzed active and chronic hospital treatment costs of these patients in the period of 12 months before the stroke and in the following first and second 12 months. Data were collected by sex and age (age groups: 25-44, 45-64, over 65). We studied patients hospitalized in May 2003 with the ICD-10: I60-64 main diagnosis but not being treated with the same diagnosis in the previous 24 months. In the first 12 months of the active care the burden of the disease was (male vs. female) 65+: 254.6 vs. 205.8; 45-64: 341.4 vs. 280.5; 25-44: 370.1 vs. 306.1 thousand HUF per patient. In the second 12 months the costs were 50.6 vs. 36.2; 24.2 vs. 32.6; 27.6 vs. 24.8 thousand HUF respectively. In the first year following the episode the costs of the chronic hospital treatment were (age groups as above) 23.3 vs. 31.3; 28.9 vs. 22.2; 22.8 vs. 22.5 thousand HUF. A year later the chronic hospital costs were 9.0 vs. 10.9; 6.7 vs. 12.2; 1.4 vs. 38.1 thousand HUF respectively. Average costs of stroke are higher in the case of males as are in the case of females, 364.8 vs. 303.0 thousand HUF in the first 24 months. The remarkable difference results from active hospital treatment costs (331.5 vs. 262.1 thousand HUF), while the discrepancy is smaller in the chronic hospital care (33.3 vs. 40.9 thousand HUF).]

[AIM OF THE STUDY - To perform functional MRI experiments at low magnetic field, and to set up routine protocol to help the planning of neurosurgical operations and the examination of epilepsy patients. METHODS - An optimized 2D EPI sequence was applied to yield functional MR images in basic paradigms such as finger tapping and internal word generation. Further, activation was induced also by a task involving mental navigation based on the retrieval of individually familiar visuo-spatial knowledge. RESULTS - Low resolution (matrix of 64×64) functional MR images satisfactorily visualized moto-sensor strip and speech centers. In the mental navigation task bilateral activation of formatio hippocampalis was observed. Determination of motor area was also performed in an epilepsy patient whose seizure focus had been found in the area of pre- and postcentral gyrus. The dislocation of the motor cortex was demonstrated. CONCLUSION - Functional MR images with fine quality can be obtained in basic paradigms even at low magnetic field if MR imaging parameters and paradigms are optimized.]

[The early-onset generalised dystonia is a dyskinetic movement disorder with a wide variety in phenotype and poor response to pharmacological treatment. A mutation on the DYT1 gene is responsible for the disease in more than 50% of cases with typical early-onset dystonia beginning in a limb. We describe the medical history of two brothers with first signs of focal dystonia at age 12 starting with right side lower limb dystonia of the older brother and writers cramp of the younger one. In both over a period of 6 and 10 years dystonia generalised. The negativ results of MRI, electrophisiological testing and muscle biopsy corroborate the diagnosis of primary dystonia. The DNA from the older patient was tested for the 3 bp deletion in exon 5 of the DYT1 gene by restriction enzyme. The positive result confirmed the diagnosis of early-onset primary dystonia. A short synopsis of routine molecular genetic tests indications and treatment options is outlined.]

[Introduction - Vinpocetine has been widely used in the treatment of ischaemic cerebrovascular diseases and dementias of vascular type. Chronic cerebral hypoperfusion plays an important role in the development of certain types of dementia. In consequence of complex mode of action vinpocetine plays a significant role in the improvement of cerebral hypoperfusion. The symptoms of mild cognitive impairment considered as “predementia” are similar to those of dementia, although milder. Aims - The authors investigated the characteristics of the blood flow parameters of patients with ischemic stroke and mild cognitive impairment both in resting conditions or following chemical stimulus as well as they investigated the severity of mental deterioration in the two patient groups. In a pilot study the authors examined the influence of 12-week long oral vinpocetine therapy on the blood flow parameters and cognitive functions in the two patient groups. Methods - The authors studied the blood flow velocity of a. cerebri media in resting conditions and after 30 sec of breath holding with transcranial Doppler before treatment and after a 12-week long oral vinpocetine treatment. At the same time psychometric tests (MMSE, ADAS-Cog) were used in order to examine cognitive functions, while the general condition of the patients were scored by Clinical Global Impression (CGI) scale. Results - After a 12-week long oral vinpocetine treatment the increase of blood flow velocity in resting conditions compared to the baseline values was significant in the vascular group. The percent increase of mean velocity after the breath holding TCD test showed a significant increase compared to the baseline in both patient groups. The authors found a significant improvement of cognitive functions after a 12-week long oral vinpocetine therapy using psychometric tests. The improvement was identical in both groups. The general condition of patients improved significantly according to both the investigator's and the patients' opinion; patients with mild cognitive impairment judged the improvement higher. Conclusions - Vinpocetine improved the cerebrovascular reserve capacity in both patient groups and favourably influenced the cognitive status and general condition of patients with chronic hypoperfusion. The authors recommend the use of vinpocetine for the treatment of patients with mild cognitive impairment.]

[The case of a 57 year-old-man is reported who has been treated several times because of his relatively expedite mental decline which has begun four years before his death. His first complaints were forgetfulness, mild changes in his behaviour, confusion and difficulty in speech. The neuropsychiatric examinations displayed a mild difficulty in naming and sometimes comprehension of words, although his speech was gramatically correct. Furthermore the patient presented a very severe decrease in short term memory with dementia and confusion. These symptomes together with the results of CT and test examinations established the diagnosis of Alzheimer's disease. Finally pneumonia afflicted the patient during the last hospitalization and he died. Histopathological examinations of the brain showed a severe, mainly temporofrontal atrophy caused by an extensive cortical neuronal loss and gliosis without neurofibrillar degenerations and senile plaques which characterize the Alzheimer's disease. Tau-positivity Pick- and Lewy-bodies may not be found. The loss of neurons associated in some places with spongiosity of laminar form. The ubiquitine-positive intracytoplasmic inclusions proved to be the most characteristic feature in the swollen neurons. These mainly occurred in the gray matter of the mediobasal part of the temporal lobe. The positivity of GFAP immunocytochemistry revealed a definite astrocytosis in the affected parts of the gray matter. In the temporal and frontal cortex scattered ballooned cells (achromatic or Pick cells) were seen in αB-crystallin immunohistochemistry. These findings confirmed the diagnosis of the case of frontotemporal lobar degeneration with ubiquitin-positive intraneuronal inclusions (FTLD-U) without tau-positivity. The separation of the different forms in the group of the frontotemporal dementias is recommended by means of the modern immunocytochemical examinations.]

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.

[Efficacy of anticoagulation with vitamin K antagonists in acut stroke patients with atrial fibrillation - Hungarian results]

SAS Attila, CSONTOS Krisztina, LOVÁSZ Rita, VALIKOVICS Attila

[Background and objective - An estimated 20% of ischemic strokes are of cardiogenic origin, half of which is associated with atrial fibrillation (AF). Anticoagulation treatment of patients with this arrhythmia reduces their risk of stroke. Effectiveness and safety of oral anticoagulant therapy with vitamin K antagonists (VKA) is limited, however, by their well-known narrow therapeutic window and the substantial inter- and intraindividual variability of INR values depending on genetic and dietary factors as well as drug interactions. Our objective was to evaluate the prevalence of adequate anticoagulation and the level of anticoagulant effect actually achieved among patients with AF hospitalized for acute stroke. Methods - Patients with AF admitted to our hospital ward in 2012 for acute stroke (n=226) were included in the analysis. Using descriptive statistics, relevant clinical and therapeutic characteristics of the patients were assessed, with special reference to the INR values on admission (among patients with known AF), and the clinical outcomes. Results - Of the study cohort, 170 patients had a diagnosis of AF before the admission for stroke, but 47% of them did not take anticoagulants. Patients who suffered stroke while on anticoagulants (83 on VKA, 7 on low-molecular-weight heparins), were in most cases (75%) out of the therapeutic INR range, typically undertreated (INR<2). Overall, inadequate or completely absent anticoagulation was documented in 81% of the stroke cases occurring in patients with known AF. Of the entire study cohort, 41% was discharged home, 34% required continued institutional care, and 25% died. Conclusions - The inadequacy or lack of anticoagulation was observed in the vast majority of acute strokes in patients with known AF. These cases are often related to the well-documented limitations of VKA therapy in terms of its safety, tolerability and/or practical aspects. To prevent them, important changes are warranted in the anticoagulation practice, including the closer control of VKA therapy and the broader use of new oral anticoagulants.]

[Genetics and hemostasis in young stroke patients]


[Background and purpose - The classical risk factors did not explain all the possible ethiology of cerebral stroke. Genetic polymorphisms responsible for thrombophilia were implicated recently as risk factors of stroke. In this geneticoepidemiological study the author’s aim was to analyse the tendency of genetic polymorphisms to cluster in a cohort of young and elderly stroke patients and in healthy subjects in Hungary. Methods - 253 patients with stroke were compared with 173 healthy blood donors on the basis of genetic polymorphisms of platelet GP IIb/IIIa receptor (33 LeuPro), prothrombin gene G20210A, Factor V Leiden mutation, ACE I/D, methylenetetrahydrofolate reductase (MTHFR) and β fibrinogen gene G455A. These data were acquired using PCR. Questionnaires were used to investigate the family history and to determine the risk factor profile. The subtypes of stroke were analysed in a stroke cohort grouped according to different polymorphisms. Results - An increased frequency of GP IIIa heterozygousity was found as compared to a West-European stroke cohort (31% versus 19%). The prothrombin gene variant (2.9% European and 4.8% in Hungary) was also found to increase in frequency. In young stroke patients (age <50) compared with control subjects the odds ratios were higher: in prothrombin gene (OR: 4.9), in Leiden mutation (OR: 1.67), in fibrinogen gene (OR: 1.64) and in MTHFR(+/+) (OR: 1.58). Clustering of two polymorphisms could only be detected in young patients. These clustering polymorphisms were GP IIb/IIIa with prothrombin G20210A variant (OR: 6.74, 95% CI 1.1-18.2) and prothrombin gene variant with MTHFR (OR: 5.3, CI95 1.2-8.3). Conclusion - Selected and clustered genetic polymorphisms of haemostatic factors could be responsible for the high stroke morbidity in Central Europe. The presence and clustering tendency of these factors have been described in young stroke victims.]

[Neurological effects of tolperisone]


[Spasticity, as a result of cortical motor neuron injury, is a frequent symptom in neurological disorders. Tolperisone is a centrally acting muscle relaxant, which has been used for 50 years in clinical practice. Tolperisone has a membrane-stabilising effect and it inhibits voltage-gated sodium and calcium channels. Although it targets the central neural system, it has no sedative side effects, in contrast to other muscle relaxants. Besides clinical experiences of past decades, the efficacy of tolperisone has also been proved in a study fulfilling evidencebased criteria. In this double-blind, placebo- controlled, randomised, parallel group study, 78.3% of tolperisone-treated patients had an at least one-point reduction on the Asworth scale (a 5-grade scale used the measure spasticity), compared with 45% in the placebo-treated group. The excellent tolerability of tolpe-risone is demonstrated by the finding that the number of adverse events was greater in the placebo group than in the tolpe-risone group. Taking these facts in consideration, tolperisone is a safe and effective drug to treat spasticity.]


[The risk factors of osteoporosis and osteoporotic fractures in Hungarian women: the results of the NOKK study]

MEZŐ Tibor, TABÁK Ádám, BHATTOA Harjit Pál, LAKATOS Péter

[INTRODUCTION - It is widely accepted from Western European and the US studies that race and geography significantly affect the risk for osteoporosis. Less is known about similar associations in Eastern European subjects. Our aim was to describe the risk factors for osteoporotic fractures and osteoporosis in a selected female population in a cross-sectional, multi-center study performed under the guidance of the Hungarian Society for osteoporosis and Osteoarthrology. MATERIAL AND METHOD - From 10 randomly selected regional osteoporosis centers, altogether 2602 women >18 years of age, referred with any osteoarthrological reason, participated. During their visit data on risk factors, blood pressure, anthropometry, and bone mineral density were collected. RESULTS - Using multiple regression we found that older age, lower diastolic blood pressure, family history of bone fracture, fall in previous year and lower T-score were independently related to fractures. Independent risk factors for femoral osteoporosis included older age, lower weight, family history of fracture, less physical activity, fall in the previous year and glucocorticoid treatment. DISCUSSION - Our study is the first large-scale epidemiological survey describing risk factors of osteoporosis and fractures in a Hungarian female population. Our data may suggest that lower diastolic blood pressure might be related to osteoporotic fractures.]
