[Background - The Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) has been published in 2008 as the successor of the original UPDRS. The MDS-UPDRS organizing team developed guidelines for the development of official non- English translations consisting of four steps: translation/back-translation, cognitive pretesting, large field testing, and clinimetric analysis. The aim of this paper was to introduce the new MDS-UPDRS and its validation process into Hungarian. Methods - Two independent groups of neurologists translated the text of the MDS-UPDRS into Hungarian and subsequently back-translated into English. After the review of the back-translated English version by the MDS-UPDRS translation administration team, cognitive pretesting was conducted with ten patients. Based on the results of the initial cognitive pretesting, another round was conducted. For the large field testing phase, the Hungarian official working draft version of MDS-UPDRS was tested with 357 patients with Parkinson’s disease (PD). Confirmatory factor analyses (CFA) determined whether the factor structure for the English-language MDS-UPDRS could be confirmed in data collected using the Hungarian Official Draft Version. To become an official translation, the Comparative Fit Index (CFI) had to be ≥0.90 compared to the English-language version. Results - For all four parts of the Hungarian MDS-UPDRS, the CFI was ≥0.94. Conclusion - The overall factor structure of the Hungarian version was consistent with that of the English version based on the high CFIs for all the four parts of the MDSUPDRS in the CFA; therefore, this version was designated as the ‘OFFICIAL HUNGARIAN VERSION OF THE MDSUPDRS.’]

[Association of temporal lobe inflammatory leukoencephalopathy with two B cell malignancies]

GARZULY Ferenc, HAHN Katalin, IVÁNYI János László, KERESKAI László, GÁBOR Valéria, KOVÁCS G. Gábor, BUDKA Herbert, KÁLMÁN Bernadette

[Identification of etiological connections among virtually distinct diseases in a patient may be sometimes challenging. We report a unique case with two B cell malignancies and an inflammatory leukoencephalopathy. Three days prior to admission, the elderly male patient developed fatigue, headaches, recurrent vomiting, memory disturbances, depression and somnolence. Clinical, laboratory and imaging evaluations as well as post mortem histological studies were performed. Simultaneous presence of primary central nervous system B cell lymphoma, temporal lobe inflammatory leukoencephalopathy and multiple (smoldering) myeloma, was revealed by the detailed work up in the treatmentnaïve patient. Based on recent data from genomic studies, we propose that a sequential evolution of molecular pathology lead to the co-occurrence of multiple myeloma and primary central nervous system B cell lymphoma in this patient, and interpret the development of the temporal lobe leukoencephalopathy as a likely paraneoplastic complication of smoldering myeloma.]

Retinal morphological changes during the two years of follow-up in Parkinson’s disease

ATUM Mahmut, DEMIRYÜREK Enes Bekir

The study aims to investigate the relationship between the progression of idiopathic Parkinson’s disease (IPD) and retinal morphology. The study was carried out with 23 patients diagnosed with early-stage IPD (phases 1 and 2 of the Hoehn and Yahr scale) and 30 age-matched healthy controls. All patients were followed up at least two years, with 6-month intervals (initial, 6th month, 12th month, 18th month, and 24th month), and detailed neurological and ophthalmic examinations were performed at each follow-up. Unified Parkinson’s Disease Rating Scale part III (UPDRS Part III) scores, Hoehn and Yahr (H&Y) scores, best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness were analyzed at each visit. The average age of the IPD and control groups was 43.96 ± 4.88 years, 44.53 ± 0.83 years, respectively. The mean duration of the disease in the IPD group was 7.48 ± 5.10 months at the start of the study (range 0-16). There was no statistically significant difference in BCVA and IOP values between the two groups during the two-year follow-up period (p> 0.05, p> 0.05, respectively). Average and superior quadrant RNFL thicknesses were statistically different between the two groups at 24 months and there was no significant difference between other visits (p=0.025, p=0.034, p> 0.05, respectively). There was no statistically significant difference in CMT between the two groups during the follow-up period (p> 0.05). Average and superior quadrant RNFL thicknesses were significantly thinning with the progression of IPD.

[Dopamine agonists in Parkinson’s disease therapy - 15 years of experience of the Neurological Clinics from Tîrgu Mureș. A cross-sectional study ]

SZÁSZ József Attila, CONSTANTIN Viorelia, MIHÁLY István, BIRÓ István, PÉTER Csongor, ORBÁN-KIS Károly, SZATMÁRI Szabolcs

[Background and purpose - There is relatively few data regarding the usage of dopaminagonists for the treatment of Parkinson’s disease; furthermore, there are no publications regarding Central- and Eastern-European countries. The aim of the study was to evaluate the use of dopamine agonists as a therapeutic option amongst Parkinson’s disease patients admitted to the Neurological Clinics of Tîrgu Mures during the last 15 years. Methods - In our study we investigated the data of all Parkinson’s patients treated at our clinics between the 1st of January 2003 and the 31st of December 2017. We analyzed the particularities of dopamine agonists’ usage based on the therapeutic recommendations from the final report of these patients. Regarding time since the diagnosis, we divided the patients in two groups: less than or equal to 5 years and more than 5 years. Results - During the studied period a total of 2379 patients with Parkinson’s disease were treated at the Clinics. From the 1237 patients with disease duration under 5 years 665 received dopamine agonists: 120 as monotherapy, 83 together with monoamine oxidase inhibitors and in 234 cases associated with levodopa. The remaining 228 patients were treated with a triple combination of levodopa, dopamine agonists and monoamine oxidase inhibitors. In patients suffering from Parkinson’s disease for more than 5 years, in 364 cases out of 653 a dopamine agonist was part of the therapy. Conclusion - The usage of dopamine agonists was similar to the data presented in other studies. We consider that clinicians treating the disease should, with the necessary prudence, use the available and recommended dopamine agonist with the utmost courage to their maximum therapeutic potential.]

[The 123I-FP-CIT dopamine transporter SPECT imaging is a sensitive method to assess functional dopaminergic neuron terminals in the striatum. The method has also been available in Hungary for years. There are two main indications: (i) to help differentiate essential tremor from clinically uncertain Parkinsonism, including patients with early symptoms and (ii) to help differentiate dementia with Lewy bodies from Alzheimer’s disease. The aim of this paper is to review 123I-FP-CIT SPECT imaging based on international data/guidelines and our own experiences, thereby assisting nuclear medicine practitioners and neurologists.]

Insights into the structure and function of the hippocampal formation: Relevance to Parkinson’s disease

GYÖRFI Orsolya, NAGY Helga, BOKOR Magdolna, KÉRI Szabolcs

The link between the hippocampus and declarative memory dysfunctions following the removal of the medial temporal lobe opened unexplored fields in neuroscience. In the first part of our review, we summarized current theoretical frameworks discussing the role of hippocampus in learning and memory. Several theories are highlighted suggesting that the hippocampus is responsible for assembling stimulus elements into a unitary representation that later can be utilized to simulate future events. The hippocampal formation has been implicated in a growing number of disorders, from neurodegenerative diseases to atypical cognitive ageing and depression. Recent neuroimaging studies provided new opportunities to study in detail the hippocampal formation’s role in higher levels of the nervous system. We will present data regarding the regional specialization of the hippocampus in experimental models developed for healthy and neurological conditions with a special focus on Parkinson’s disease. Combined evidence from neuroimaging studies suggested that hippocampal volume is reduced in non-demented, newly diagnosed patients with Parkinson’s disease, which is associated with impaired memory performance. These findings proposed that, beyond the well-known striatal dopamine loss, impaired hippocampal synaptic plasticity may contribute to cognitive and affective impairments in early Parkinson’s disease.

TÓTH Adrián, TAKÁTS Annamária

[Parkinson’s disease is the elderly people’s condition which increases the risk of infections in the upper airways in its ad­vanced stages. Specific diseases (as hypertension, diabetes mellitus), older age and the male sex are significantly worsening the course of COVID-19. It would be challenging to examine parallel these diseases, since they are raising two important ques­tions. First, if Parkinson’s disease be a risk factor of COVID-19 morbidity and mortality. Se­condly, how the COVID-19 pandemic can influence the Parkinson’s disease patients. The authors are seeking answers to these questions based on the published results in the topic concerned.]
