[INTRODUCTION - Modern radical radiotherapy can be an effective alternative of radical prostatectomy in low risk patients with prostate tumor. Our objective was to demonstrate the feasibility of transperineal MR-guided prostate interventions in an open MR unit and to present our early clinical experiences on canines. METHODS AND MATERIALS - The procedures were performed on 5 canines in an open-configuration 0.35T MR scanner. For interventions an MR compatible custom-made device was used. The canines were placed in the right lateral decubitus position. Template reconstruction, trajectory planning, target and OAR delineation were based on T2 FSE images. For image guidance and target confirmation, fast spoiled gradient-echo (FSPGR) sequence was used. MR compatible coaxial needles were inserted through the perineum to the base of the prostate. After satisfactory position was confirmed, brachytherapy catheters were placed through the coaxial needles, which were then removed. RESULTS - Mean and standard deviation of the needle displacements was 2.2 mm±1.2 mm, with a median of 2 mm. 96% of the errors were less than 4.0 mm. Implantation induced prostate motion was measured with a mean of 10.3 and 2.3 mm in cranio-caudal and transverse directions. Significant movement was only observed during the first 4 needle insertions. The average time needed for each step was: anesthesia 15 minutes, setup and positioning 15 minutes, initial imaging 15 minutes, template registration and projection 15 minutes, contouring, trajectory planning, insertion of 10 needles 60 minutes. CONCLUSION - Based on our canine model experiences our method seems to be a promising approach for performing feasible, accurate, reliable and high-quality prostate MR guidance within a reasonable time span. We plan to introduce MR-guided biopsy and brachytherapy in human patients in the near future.]

[Computed tomography brain perfusion in the management of acute stroke]

BAGI Róbert, SZABÓ Tünde, MONOKI Erzsébet

[INTRODUCTION - The multidetector CT-technology made the application of perfusion CT-examination in the diagnosis of vascular brain damages possible in recently. The purpose of this study was to introduce the method and to assess the importance of computed tomography brain perfusion in emergency patient care and early diagnosis of brain ischemia. PATIENTS AND METHODS - We perform brain perfusion examinations with a 2 slice multidetector computer tomography (General Electric Highspeed NX/i, 2004) in our hospital. We examined the results of native and perfusion CT of 27 patients who underwent CT brain perfusion examination during emergency patient care in our department between 2004 January and 2006 December. We also examined if the patients got systemic thrombolysation and the patients’ condition after therapy. RESULTS - The perfusion software can make quantitative colour maps of parameters (CBF, CBV, MTT) and can visualize mean value and percentil decrease of measuring parameters. There were 18 positive and 8 negative CTbrain perfusion examinations in the examined period. One examination was technically unvaluable. CONCLUSION - By measuring blood flow's decrease the CT-brain perfusion examination can separate the reversible and irreversible damage of brain parenchyma. The examination protocol of brain vascular damages are native CT-scan, postcontrast perfusion CT-examination and CTangiography by the recommendation of international literature. Despite the multidetector CT-s and CT-perfusion technic is available for years, the CT-brain perfusion examination is not a routine process in the emergency patient care in our country.]

[Technical aspects of MR urography based on two cases]

HORVÁTH László, BOGNER Péter, NAGY Gyöngyi, BAJZIK Gábor, VANDULEK Csaba, REPA Imre

[Intravenous urography has been the gold standard in diagnostic radiology studying the urogeintal system. However, ultrasound and other cross-sectional imaging methods have brought major change in this area. Beside modern (multislice) CT examinations the methods of MR urography are more frequently applied making possible both static and dynamic examinations beyond the wellknown advantages of MR imaging. The authors describe two complemetary methods of MR urography which provide a complete evaluation of the urinary system. The first method is aimed to image stationary fluid by using heavily T2 weighted turbo spin echo pulse sequences. This measurement well depicts the dilations of the excretory system even with little or no excretion of urine. The second method is analogous with the traditional IVU, as the excretion of a less nephrotoxic gadolinium based contrast medium followed by a T1 weighted gradient echo pulse sequence (possibly dynamic) helps to visualise the renal cavities and the urinary pathways. Normal renal function is a prerequisite when using this technique in order to visualise normal and obstructed urinary pathway disorders. The use of MR urography together with traditional MR methods may significantly reduce the number of invasive examinations and methods based on X-ray radiation exposure. MR urography may be exceptionally important in the uroradiological study of distensions of renal cavities in pediatric cases, pregnant women and renal transplant patients or in case of contrast material allergy.]

[Data on blood pressure over two years in resistant hypertensive patients with lett brain stem microvascular decompression]

FEJES Imola, VÖRÖS Erika, BARZÓ Pál, ÁBRAHÁM György, LÉGRÁDY Péter

[In the background of resistant hypertension (RHT) the neurovascular pulsatile compression (NVPC) of the left rostral ventrolateral medulla may play a role. In these cases a microvascular decompression (MVD) may decrease the blood pressure (BP). The aim of this work was to investigate how the BP has changed after the MVD in the operated patients recorded at the farthest time from the MVD up to maximum 31 December 2016. We have retrospectively collected data from 9 patients whose follow-up data fór 2 years has already been published earlier. Data collection was carried out from the patient register program of the University of Szeged Albert-Szent Györgyi Clinical Centre. The MVDs were performed between 2000 and 2004. The mean follow-up time was 11.1±4.6 years. Both the systolic and the diastolic BPs were significantly lower at the time of last record compared to the BPs at the time of MVD (systolic BP 211±40 vs. 135±20 mmHg, p=0.003; diastolic BP 116±17 vs. 81±14 mmHg, p=0.007). Last recorded BPs compared to the 24-month data alsó were lower bút nőt signffi- cantly (systolic BP 148±32 vs. 135±20 mmHg, p=0.25; diastolic BP 96 vs. 85 mmHg, p=0.11). The mean number of antihypertensives at the last Office visít was nőt sig- nificantly higher compared to MVD (5.9±1.4 vs. 6.3±1.5; p=0.5) bút signfficantly increased compared to MVD +1 month data (4.7±0.9vs. 6.3±1.5; p=0.03). These results confirmed our previous opinion that in severe RHT nőt respond- ing to conventional therapy an MVD of the left side NVPC could be a therapeutic option and may guarantee a long-lasting BP reduction. Evén if the number of antihypertensives increased in the meantime, as they still responded better to therapy. ]

[Relationship of adolescents’ eating behavior and motivations with self-control and risk perception]

SZABÓ Katalin, PIKÓ Bettina

[Obesity and related diseases caused by unhealthy eating form a serious public health problem already in youth. In terms of prevention, it is essential to explore adolescents’ eating behaviors and factors influencing their diet. Our study aimed to explore adolescents’ eating behaviors, its motivations and their relation to self-control and risk perception related to eating behavior. Participants were 374 high school students (48% males; mean age: 16 years, S.D.=1.5) from Szeged and Bu­da­pest. Self-administered questionnaire was used for data collection which assessed socio-demographics, eating behaviors, mo­ti­vation, eating behavior related risk perception and self-control. Using factor analysis, we categorized eating behaviors (“junk food/drink consumption”; “health-oriented nutrition”; and “snacking and habit-oriented nutrition”), and eating motivations (“social, emotional and external motives”; “traditions and internal motives”; and “health motives”). According to correlation analysis, self-control was positively related to health-oriented nutrition and health motives and negatively to junk food/drink consumption and social, emotional and external motives. These two latter factors were associated with an increased risk perception as well. Our results draw the attention to strengthen self-control and explore the role of risk perception and eating motivations in school health education programs. ]

Association of cardiovascular risk factors and Parkinson’s disease - case-control study in South East Hungary

MARKÓ-KUCSERA Mária, VÉCSEI László, PAULIK Edit

Aims - Parkinson’s disease (PD) has the second highest incidence among neurodegenerative diseases in the world population. The study aimed to investigate the presence of some cardiovascular risk factors - dyslipidemia, diabetes, and hypertension - in PD patients and to compare their risk with non-PD population in South East Hungary. Methods - A case-control study was conducted at the Department of Neurology, University of Szeged, Hungary. The study included 1299 subjects out of which 620 patients were identified as cases of diagnosed PD and 679 as controls. Logistic regression analyses were conducted to reveal the association of vascular risk factors with PD. Results - In the univariate analysis, diabetes mellitus was positively associated with PD, while dyslipidemia showed negative association to it in the total population, and no significant associations were found between hypertension and PD. The multivariate logistic regression models showed that the odds of diabetes mellitus was higher (OR=2.86), while the odds of dyslipidemia was lower (OR=0.58) among PD patients than in the control group. Hypertension showed a different pattern by gender: the odds of registered hypertension was significantly lower in female PD patients (OR=0.68), whereas the result was not significant in males. Conclusions - This is the first study that provides a comprehensive view of the cardiovascular risk factors in PD patients in Hungary and shows considerable relationship between diabetes mellitus and PD.

[The Multiple Sclerosis Registry of Szeged]

BENCSIK Krisztina, SANDI Dániel, BIERNACKI Tamás, KINCSES Zsigmond Tamás, FÜVESI Judit, FRICSKA-NAGY Zsanett, VÉCSEI László

[Multiple sclerosis (MS) is a rare disease of the central nervous system considering the total population, the prevalence in Hungary is 83.9/100.000. The first MS registry was established in Denmark in the middle of the 1950’s. This was followed by the establishment of several national, then international databases with the number of enrolled patients in the hundred-thousands. At the beginning, the primary goal of the registries were the epidemiological surveys, focusing on the number of patients, the prevalence, the incidence, the mortality and the co-morbidity. As of today, however, with the rapid advancement and development of new disease modifying therapies (DMT) with different effectiveness and adverse reactions, the therapeutic use of the registries became even more essential: the modern, up-to-date, well established registries become integral part of the DMTs’ monitorization. The Multiple Sclerosis Registry of Szeged was first established as a “paper-based” database, then, in 2012, it was upgraded to an electronic, easily contactable and useable internet-based registry. As of today, it contains the socio-demographic and clinical data of more than 600 patients; we constantly add new patients as well as keep the registry up-to-date with the refreshment of old patients’ data. Aside from the “classical” clinical data, it can be used for the recording and assessment of the MRI scans and the data on psychopathological and quality of life assessments, which are becoming more and more important in everyday MS management. The establishment of the internet-based registry incredibly helped both the monitorization of the effectiveness of DMTs, and the success of the new epidemiological and psychopathological surveys. ]

[Unattended automated office blood pressure measurement versus classic office automated blood pressure measurement in a hypertension outpatient clinic]

LÉGRÁDY Péter, FEJES Imola, CZOMBOS András, ÁBRAHÁM György

[Accurate measurement of blood pressure is a fundamental prerequisite requirement for an appropriate management of arterial hypertension. In order to eliminate the well-known limitations of classic office blood pressure measurements, the so-called unattended automatic office blood pressure measurement method can be a solution. In 52 patients arriving for regular followup into one of the Hypertension Outpatinet Clinic of the Nephrology-Hypertension Center of the University of Szeged 3-3 blood pressure measurements were made at 1-1 minute intervals first by a doctor with an MIT5 automatic device and then in a separate room unattended, starting alone by the patient with a Hem-907 device. ]
