[β-amyloid peptide-induced intracellular calcium level changes in Alzheimer fibroblasts]

PALOTÁS András, KÁLMÁN János, LASKAY Gábor, JUHÁSZ Anna, JANKA Zoltán, PENKE Botond

[Rationale - β-amyloid peptides, comprising the major neuropathological lesions of Alzheimer's disease, have been found to form depositions in various peripheral tissues, including the skin. Neurons in the disorder succumb to the altered ionic homeostasis and some other factors caused by this toxic peptide. In line with these findings, our study aimed to find differences in biochemical processes of cultured cutaneous fibroblasts derived from sporadic Alzheimer patients and from agematched control individuals that may mirror changes in the central nervous system. Methods - Intracellular ionic homeostasis of Alzheimer and control fibroblasts was measured in Fura-2AMloaded human fibroblasts by dual wavelength spectrofluorimetry. Results - Cells derived from Alzheimer patients exhibited lower intracellular free calcium levels as compared to the control cultures. Exposure of fibroblasts to β-amyloid resulted in increased calcium concentrations of the control cells, but not of Alzheimer ones. Conclusion - Our findings indicate that Alzheimer’s disease is a systemic disorder that, among others, affects the calcium homeostasis of fibroblasts. Even though it is unknown whether the diminished ionic response of Alzheimer fibroblasts is a disease or actual status marker, it could prove to be a useful model for the analysis of Alzheimer specific changes.]

[Objective - Post-movement beta synchronization is an increase in EEG beta power after movement termination. Its characteristics in movement disorders are not well described. Tremor dominant Parkinson’s disease shows unique clinical, anatomical and biochemical features. In our study we examined the relation between the laterality of tremor and size of post-movement beta synchronisation in tremor dominant Parkinson’s disease. Methods - In a self-paced movement paradigm we measured movement duration and analyzed EEG power changes at movement-reactive beta frequencies. Results - Movement duration was significantly longer in Parkinson-patients than in controls (0.49±0.170 s, 0.35±0.087 s, p=0.013, Mann-Whitney test). There was no difference between the two hands in the control group (0.36±0.078s, 0.34±0.099 s, p=0.207, Wilcoxon-test), while Parkinson patients performed longer movement with their left hand (0.52±0.195 s, 0.46±0.148 s, p=0.049, Wilcoxon), unrelated to the side of tremor. In controls, post-movement beta synchronisation contralateral to the movement was not significantly different after right and left hand movement (108.1±68.21% and 92.1±23.43%, p=0.78 Wilcoxon). In Parkinson patients post-movement beta synchronisation was significantly smaller contralateral to the tremulous hand movement (36.9±47.79%, 104.7±91.42%, p=0.012, Wilcoxon-test). The post-movement beta synchronisation showed anterior shifting in Parkinson-patients. Conclusions - In tremor dominant Parkinson’s disease the asymmetric decrease of post-move beta synchronisation is related to the laterality of tremor rather than bradykinesia. Analysis of this phenomena might provide further insight to the pathophysiology of Parkinson’s disease.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[IDIOPATHIC TOLOSA-HUNT SYNDROME: FOUR ADDITIONAL CASES]

D Kirbas, B Topcular, ME Ozcan, N Sakalli Karagoz, G Gul, I Aslan Kalyoncu

[Idiopathic Tolosa-Hunt syndrome (ITHS) is a very rare cause of painful ophthalmoplegia characterized by unilateral orbital pain, ipsilateral oculomotor paralysis and prompt response to steroids. In this paper we report 4 additional cases of ITHS. This rare cause of painful ophthalmoplegia effects the cranial nerves due to a granulomatous lesion of unknown etiology in the cavernous sinus or superior orbital fissure. The International Headache Society redefined the diagnostic criteria for ITHS but it is still mostly a diagnosis of exclusion. Careful evaluation and follow-up is essential for diagnosis. Optimal therapy duration and dosage and prophylactic treatment in recurrent cases needs further research.]

[Hungary’s anthropometric position based on national public health screening (2010-2017). Data and correlation analysis - Part I.]

KÉKES Ede, BARNA István, DAIKI Tenno, Dankovics Gergely, †KISS István

[The aim of the study is to present a Hungarian anthropometric profile on a full-scale basis (body mass, BMI, waist circumference, waist/hip ratio, percentage of body fat, abdominal fat mass) based on the data of the “Nationwide Comprehensive Health Screening Program in Hungary 2010-2020” collected over 8 years. In the analysis we processed 70,094 women and 67,549 men. We found, that in the Hungarian society, overweight and obesity was on the rise between 2010 and 2017, and beyond 2014 its rate was ever higher. Growth of body fat and abdominal fat is characteristic for both sexes, but abdominal obesity in relative terms of waist size, waist/hip ratio and percentage of body fat is significantly higher in morbid obese women. The fact is particularly worrying that these growth trends are already present in age groups of 18-26. These signs warn us definitely that we need to take a greater part in influencing the lifestyle, eating habits of individuals and in the promotion of physical activity.]
