[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.’]

[CENTRAL NEUROENDOCRINE MECHANISMS OF GASTROPROTECTION]

GYIRES Klára

[Selye recognized the importance of activation of hypothalamic- pituitary-adrenal axis during stress and the connection between central nervous system and neuroendocrine regulation. This concept basically contributed to initiation of the studies, which revealed the importance of brain gut axis in regulation of gastric mucosal integrity. Several neuropeptides, such as thyreotrop releasing hormones, adrenomedullin, peptide YY, amylin, opioid peptides, nociceptin, nocisatin, substance P, ghrelin, leptin, orexin-A, angiotensin II were shown to induce gastroprotective effect injected centrally. Though the involvement of dorsal vagal complex and vagal nerves in conveying the central action to the periphery has been well documented, additional mechanisms have also been raised. The interaction between neuropeptides further component that may modify the gastric mucosal resistance to noxious stimulus.]

[HANS SELYE 70 YEARS LATER: STEROIDS, STRESS ULCERS & H. PYLORI]

SZABÓ Sándor

[Although Hans Selye is mostly known for his discovery & development of the stress concept, he also introduced the first physiologically sound, structure-activity classification of steroids that was also based on the chemical structure of steroids in 1943. He not only introduced the names of glucocorticoids & mineralocorticoids but discovered the anti- & pro-inflammatory properties, respectively, of these steroids in animal models. Furthermore, he not only described the first stress-induced gastric ulcers in rats (1936) & characterized the first human ‘stress ulcers’ during the air-raids in London during World War II (1943). Thus, Selye was a much more productive & creative scientist than it is generally considered.]

[A PSYCHIATRIST’S PERSPECTIVES ON STRESS, STEROIDS AND MENTAL ILLNESS]

DUNAI Magdolna

[The relationship between stress and mental illness has been extensively studied and there is a growing consensus that the occurrence of mental illness rather depends on a combination of factors than is caused by stressful external events. Significant hypothalamus pituitary adrenal axis abnormalities were observed among others in major depressive disorder and bipolar disorder. In both disorders, the extent of change in cortisol level was related to the severity of illness and to cognitive changes. Exogenous use of synthetic steroids also frequently resulted in severe psychiatric symptoms. In conclusion changes in the level of steroid hormones may cause impairments in the brain.]

[HANS SELYE AND THE STRESS RESPONSE: FROM “THE FIRST MEDIATOR” TO THE IDENTIFICATION OF THE HYPOTHALAMIC CORTICOTROPIN-RELEASING FACTOR]

TACHÉ Yvette

[Selye pioneered the stress concept that is ingrained in the vocabulary of daily life. This was originally build on experimental observations that divers noxious agents can trigger a similar triad of endocrine (adrenal enlargement), immune (involution of thymus) and gut (gastric erosion formation) responses as reported in a letter to Nature in 1936. Subsequently, he articulated the underlying mechanisms and hypothesized the existence of a “first mediator” in the hypothalamus able to orchestrate this bodily changes. However he took two generations to identify this mediator. The Nobel Laureate, Roger Guillemin, a former Selye’s PhD student, demonstrated in 1955 the existence of a hypothalamic factor that elicited adrenocorticotropic hormone release from the rat pituitary and named it corticotropin releasing factor (CRF). In 1981, Wylie Vale, a former Guillemin’s Ph Student, characterized CRF as 41 amino acid and cloned the CRF1 and CRF2 receptors. This paves the way to experimental studies establishing that the activation of the CRF signaling pathways in the brain plays a key role in mediating the stress-related endocrine, behavioral, autonomic and visceral responses. The unraveling of the biochemical coding of stress is rooted in Selye legacy continues to have increasing impact on the scientific community.]

Vestibular evoked myogenic potential responses in Parkinson’s disease

CICEKLI Esen, TITIZ Pinar Ayse, TITIZ Ali, OZTEKIN Nese, MUJDECI Banu

Background - Our objectives were to determine the differences in the vestibular evoked myogenic potential (VEMP) responses in patients diagnosed with early staged idiopathic Parkinson’s disease (PD) compared to the normal population and evaluate the vestibular system disorder causing balance-posture disorders. Second aim of this study was to investigate caloric test responses particularly in early staged PD compared to normal popu­lation. Material and methods - Thirty patients (14 females and 16 males; mean age, 60.6 ± 13.1 years) diagnosed with idiopathic PD and 28 healthy subjects (20 males and 8 females; mean age, 59.1 ± 6.4 years) were included. The patient and control groups were subdivided according to their age, gender and the patient group was subdivided according to onset time of the Parkinson symptoms, Hoehn-Yahr staging. The subgroups were compared for VEMP and caloric test responses. Results - There were no significant differences between the study and control groups for right and left VEMP measurements. Patients over 60 years and under 60 years did not show significant differences in terms of right and left mean VEMP measurements. However, P1 amplitude was significantly lower in patients over 60 years old (P = .004). Gender, disease duration, BERG balance scale and Hoehn-Yahr stage had no effect on the VEMP amplitudes. There was no significant correlation with the side of Parkinsonian symptoms to the side of canal paresis (P = .566) and the side on which no VEMP response was obtained in caloric test. Conclusion - VEMP responses were not different between PD and healthy subjects. VEMP P1 amplitude was decreased with age in PD group. Canal paresis and symptoms side were not statistically correlated in caloric test.

[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.]

[Mentalizing deficit in neurological disorders: a review article]

HEROLD Róbert, VARGA Eszter, MIKE Andrea, TÉNYI Tamás, SIMON Mária, HAJNAL András, FEKETE Sándor, ILLÉS Zsolt

[Introduction – Mentalization is the ability to attribute mental states (intentions, desires, thoughts, emotions) to others, and hence to predict their behaviour. This ability fundamentally determines our participation in social relationships and adaptation to society. A significant proportion of the disorders of the central nervous system (CNS) affects those brain structures and neurotransmitter systems that play a role in the mentalizing processes. Accordingly, a number of CNS disorders may be associated with mentalizing deficits, which may affect the outcome of these diseases. Here, we review recent research on mentalizing abilities in neurological diseases. Methods – An internet database search was performed to identify publications on the subject. Results – Sixty-two publications in English corresponded to the search criteria. These publications reported impaired mentalization in several neurological disorders (e.g. epilepsy, Parkinson’s disease, multiple sclerosis, dementias, traumatic brain injury). Discussion – The results indicate that a number of neurological disorders associate with mentalizing deficit. This deficit is often present in the early stages of the diseases and has a prognostic value, which in turn emphasizes the importance of the early detection and adequate rehabilitation.]

[Parkinson’s disease from the perspective of general practice]

KOVÁCS Norbert

[Due to the recent developments in medicine, Parkinson’s disease became a relatively well-treatable condition. Recently the working abilities and the health-related quality of life of our patients dramatically improved by the application of optimal pharmacological and functional neurosurgical treatment options. Despite of these good progresses, the curative treatment option is still warranted. The aim of this review article is to present those pharmacological, neurosurgical and other treatments, which can improve the condition and quality of life of the patients. We also discuss the major concerns important for general practitioners including the assessment of driving abilities.]

[Clinical studies on pramipexol retard]

KLIVÉNYI Péter, VÉCSEI László

[Pramipexol retard is the newest drug for the treatment of Parkinson’s disease. The prolonged release of the agent in this preparation allows a more continuous dopaminergic stimulation than previous preparations, without reducing the agent’s already known and proven clinical efficiency. In addition, it has a more favourable adverse effect profile than previous preparations, and patient compliance can also be better as it needs to be taken only once daily. These benefits have been proven in recent clinical studies, of which the most important ones are reviewed here.]
