[Objective - Although the primary purpose of the study reported here was to identify stroke risk factors among the residents of a village in eastern Hungary, the study also included a multi-faceted survey conducted in 1992-94 to ascertain the somatic, mental and socio-economic conditions of the residents. Here we report data from the survey on prevalence of mental disorders (a cross-sectional descriptive study). Method - The screenings included the following tests administered to 535 subjects: anxiety, depression, dementia, neurosis were measured; recent medical records were compared to survey data for 330 of the same subjects. Findings - The summary of prevalence of mental disorders measured in this study was as follows: anxiety 34.7% (severe), dementia 44.68% (mild), depression 66% (mild), 15.94% (medium), 7.88% (severe), neurosis 66.73% (mild, medium, and severe). Medical records maintained by village physicians since 1960 differed from the results obtained in the present study. A treatment gap was observed between mental health treatment for neurosis, as indicated by medical records, and the diagnostic prevalence of neurosis as measured by the survey instruments: there were three times as many people diagnosed as neurotic in the survey as had been noted in village medical records. Additionally, the unique position of cerebrovascular alteration was established between the mental and somatic factors. Conclusion - The study demonstrates the successful simultaneous collection of a wide spectrum of data on somatic conditions, mental disorders, and socio-economic status of the subjects. The study showed that 1. patientcentered medical care can simultaneously address both somatic and mental factors; 2. it is possible to decrease the treatment gap in mental health; 3. there is value in systematic collection of data in order to optimize the planning of prevention, health care costs and decision making.]

[Emotion-related brain regions (in English language)]

SZILY Erika, KÉRI Szabolcs

[Converging data from human functional imaging in healthy subjects, neuropsychological studies of brain-damaged patients, and non-human neurophysiology indicate that emotional processing is linked to anatomically distinct and well-defined brain regions. A main characteristic of emotion-related brain regions (orbitofrontal cortex, anterior cingulated cortex, amygdala, insula) is their reciprocal anatomical connectivity with each other as well as with neuromodulatory systems (e.g., serotonergic dorsal raphe, cholinergic nucleus basalis of Meynert, and dopaminergic ventral tegmentum) and with other brain areas involved in sensory, motor, and cognitive functions. These structures mediate the representation of stimulus values, the affectleaden enhancement of sensory processing, and the predictions of values associated with actions in order to bias decision-making in uncertain situations. In this review, we discuss new results from the functional neuroanatomy of these brain circuits and outline their significance in the emergence of various psychopathological phenomena.]

[REMOVAL OF INTRASPINAL SPACE-OCCUPYING LESIONS THROUGH UNILATERAL PARTIAL APPROACH, THE “HEMI-SEMI LAMINECTOMY”]

BANCZEROWSKI Péter, VAJDA János, VERES Róbert

[Objective - The conventional dorsal surgical approaches used in removal of intraspinal space-occupying lesions by unroofing the spinal canal, often result the destruction of dorsal bony structures, sacrifice the interspinosus/supraspinosus ligament complexes and stripping of the paraspinal muscles causing a pathologic biomechanical milieu may lead to spinal deformities, instability. Various less invasive techniques exist to save the integrity and to prevent the instability of the spinal column and allow removal of intraspinally located space-occupying lesions at the same time. The authors discuss the experiences with unilateral partial laminectomy approach in removal of intraspinally, mainly lateral, intra- or extradurally located pathologic lesions. Methods - The unilateral partial laminectomy, in which the laminas were preserved (hemi-semi laminectomy) was performed in 86 symptomatic patients to remove space-occupying intra- or extradurally located lesions of the cervical, thoracic and lumbar spinal canal. Symptoms were local or radicular pain, motor, sensory and vegetative disturbances. Results - Adequate surgery of the lesions located within the spinal canal was achieved in all patients using this approach. The hemi-semi laminectomy was performed at one spinal level in 68 patients, two levels in 15 and three levels in 3. The affected spine was the cervical in 16, the cervico-thoracic in 6, the thoracic in 35, the thoraco-lumbar in 10 and lumbar region in 19 cases. Histological results were as follows: 32 intradural meningeomas, 27 neurinomas, 10 ependymomas, 3 arachnoid cysts, 2 cavernomas and extradurally 4 epidural haemorrhage, 5 epidural abscesses and 3 dural vascular malformations. Conclusion - The unilateral partial laminectomy (named hemi-semi laminectomy) approach for the mainly laterally located intra- or extradural lesions, confined to one side, allow to minimize resection of and injury to tissues not directly involved in the pathologic process, while affording a safe and thorough removal of space-occupying pathologies and decompression of neural structures located in a spinal canal. Two additional advantages come from this technique in cases of misjudged level or at re-operation.]

[DYNAMICS OF THE TRIPLE RING, VOLUMETRICAL ANALYSIS, PREDICTIONS FOR TREATMENT PLANNING]

KOLUMBÁN Zsuzsa, VIOLA Árpád, MAJOR Tibor, BAJZIK Gábor, JULOW Jenő

[Objective - The aim of this study is to reveal the volumetrical changes in tumor necrosis, reactive zone and edema following low-dose rate I-125 interstitial irradiation of 20 inoperable (partially irresecable, partially inoperable) lowgrade gliomas. Methods - The volumes of the three regions on imagefused control CT/MRI images were measured for a 24- month period with 36 occasions. The delivered dose on the tumor surface (GTV) was 50-60 Gy. Dose planning and image fusion were performed with the BrainLab Target 1.19 software, mathematical and statistical computations were carried out with the Matlab Numeric Computation and Visualization software. The control images with the „triple ring” were fused with the planning images, and the isodose curves were adjusted to them. Results - Relative volumes normalized to volume of the reference dose were calculated and plotted in the time domain. The mean values of volumes were determined from the patients' measured data then a polynom was fitted to the mean values using the polynomial curve fitting method. The accuracy of our results were verified by statistical tools. Conclusions - The new polynomial prediction approach using image fusion analysis of the volume of tumor necrosis, reactive ring and edema caused by interstitial irradiation as a function of time provides valuable information for 1. selecting the best patient’s treatment option, 2. following up patient’s condition and 3. planning reirradiation or reoperation if necessary.]

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.

[Effect of two month positive airway pressure therapy on the structure of sleep, cognitive function and anxiety]

CSÁBI Eszter, VÁRSZEGI Mária, SEFCSIK Tamás, NÉMETH Dezsõ

[Obstructive sleep apnea is a common disorder, characterized by repeated episodes of upper airway obstruction during sleep, resulting intermittent hypoxia and disruption of the normal sleep pattern, which caused cognitive dysfunction in these patients. Nasal continuous positive airway pressure is the treatment of choice for this disorder. The aim of the study is to evaluate the effect of short-term positive airway pressure on sleep pattern (polisomnographic measures), cognitive function and anxiety. Twenty four newly diagnosed and previously untreated patients with obstructive sleep apnea were evaluated a battery of neuropsychological tests before and after 2 and a half months of the treatment. We focused on working memory, short and long-term episodic memory, executive functions, anxiety and subjective sleepiness. Our results showed that the two and half month of treatment improved the respiration during sleep, sleep pattern and the subjective sleepiness. We found improvement in short- and long-term verbal memory, and complex working memory. Despite of treatment we did not find improvement in visuospatial learning. These results reveal that 2 and a half months of positive airway pressure treatment restored not only the normal respiration during sleep and normal sleep pattern, but also the cognitive functions. Our study suggests that cognitive dysfunction is at least partial reversible in obstructive sleep apnea patients after positive airway pressure treatment.]

[Pathomechanism, symptoms, differential diagnosis and therapy of fibromyalgia]

KELEMEN Judit

[Fibromyalgia is a chronic, non-inflammatory pain syndrome characterised by diffuse muscle pain and increased tenderness of specific tender points. The exact cause or pathomechanism of the disease is unknown. In the background, nociception and the pain processing pathways of the central nervous system are suspected as dysfunctional. The disease occurs primarily in middle-aged women. Occurence of fibromyalgia is between 1-4%, increasing up to 20% in a rheumatology clinic. In Canada, the cost of treatment of fibromyalgia was 350 million $ in 1993. Unfortunately, in Hungary no similar data is available. It is frequently joined by different vegetative and functional symptoms. One characteristic feature is insomnia, causing typical morning fatigue in patients. Effective therapy has yet to be found, although successful treatment may be achieved with drug therapy (amitryptilin), psychotherapy and aerobics with supplemental electro- and hydrotherapy. Patient education and involvement is also important for good therapeutic results and for the ability to return to work as soon as possible.]

[Interrelations between antidepressants and diabetes]

HARGITTAY Csenge, GONDA Xénia, MÁRKUS Bernadett, VÖRÖS Krisztián, TABÁK Gy. Ádám, KALABAY László, RIHMER Zoltán, TORZSA Péter

[Diabetes and depression are frequent comorbidities. They are a heavy burden by themselves, however, as comorbidities increase additionally the number of diabetes-related complications, morbidity, and mortality. In the background of interrelations, there are both well-known and hypothetical mechanisms. The aim of the present review is to outline these interrelations between antidepressants and diabetes and to discuss the effect of medications on carbohydrate metabolism respectively. Anti­depressant treatment on the one hand may improve mood, cognitive function and medication adherence leading to an improved glucose metabolism, on the other hand through their metabolic side effects, they may worsen carbohydrate metabolism. Concerning metabolic side effects, selec­tive serotonin reuptake inhibitors are the sa­fest, while tricyclic antidepressants and mo­noamine oxidase inhibitors should be administered under close monitoring. Se­rotonin and noradrenaline reuptake inhibitors may deteriorate gly­cae­mic control via increased noradre­nergic activation. Novel antidepressants, how­ever, have a neutral or positive impact on gly­caemic measures. Screening for and temporally adjusted treatment of depres­sion may decrease the risk of comorbidities ge­nerated complications. While caring for diabetic patients with depression, one should consider metabolic side effects of antidepressants and close monitoring of carbohydrate metabolism.]
