[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.]

[The role of intergenerational stress in the background of anorexia nervosa]

TÚRY Ferenc, PÁSZTHY bea

[In childhood and adolescence, family therapy is a crucial therapeutic method in the treatment of anorexia nervosa. Among the family stress factors there are the tensions often too obvious between the parental and grandparental generations. Three case reports are presented, where the transgenerational tensions played an important role in the family of a young patient, suffering from anorexia nervosa. During the family therapy, the treat­ment of interrelated family stress factors and focusing on transgenerational relations proved to be crucial in the successful outcomes. While treating anorexia nervosa by family therapy there are not only important the recognition and treatment of tensions within the nuclear family, but also those of stressed relations emerging from grandparental generation through multigenerational transfer mechanisms. This treatment may be successful either with the grandparent’s inclusion, or exclusion. ]

[Epilepsy in coronavirus pandemic]

SZŰCS Anna, HALÁSZ Péter, NARULA Lalit

[We aim to review the impact of COVID-19 pandemic on epilepsy and epilepsy-care. While the virus has no specific link with epilepsy, it may affect the nervous system both directly and indirectly, leading to seizures in several ways. The hyper-coagulable state occurring with the infection may cause strokes leading to seizures. The infection may first manifest in the form of disturbances of consciousness and behaviour, seizures, and even status epilepticus. The interactions of antiviral/antiepileptic drugs need to be taken into account during treatment. The hypercoagulable state induced by COVID-2 infection may cause stroke, which leads to seizures. The infection can occur also as an impaired consciousness of non-epileptic origin. Interactions of antiviral/antiepileptic drugs have also to be taken into account. The pandemic itself as well as quarantines and social distancing may cause anxiety and insomnia, challenge continuous antiepileptic supply; each one carrying the risk of seizing. Young epilepsy patients with learning disabilities and mental health issues are most vulnerable, justifying their hyper-protection. The danger of infection has highlighted the role of telemedicine. Internet-based video communication may ensure full care for chro­nic patients. Those methods favour bes­­ted patients with higher education. Epilepsy does not increase directly the risk of infection, but its comorbidities may worsen the course of the disease. Brain lesions and hypoxia, stress, insomnia and fever joining the infection increase seizure susceptibility. Because the danger of infection ma­de telemedicine an essential tool of pa­tient care, education and better computer supply for those in need is crucial. ]

Mental health of physicians - nationwide representative study from Hungary

GYŐRFFY Zsuzsa, GIRASEK Edmond

Background and aim - Somatic and mental health and stress factors of physicians became an issue of growing interest in both national and international researches. Our aim is to give an overviewing analysis of Hungarian physicians’ mental health state. Methods - Representative, cross-sectional, quantitative survey on a representative sample of Hungarian physicians (n=4784). The control group was formed by the population group of a national survey conducted by “Hungarostudy 2013” (n=2000). Results - Suicidal thoughts (18.8% vs. 9.6%, p<0.001), the scores of Somatic Symptom Scale (PHQ-10, 20.4% vs. 13.6%, p<0.001) were significantly higher among physicians. The suicidal attempts (1.9% vs. 3.5%, p=0.053) and BDI depression scores (7.9% vs. 29.5%, p<0.001) were significantly higher in the control group. High Perceived Stress Scale (PPS) scores occurred in 43.3% of the physicians sample, and 43.4% of them had high scores in the Athenian Insomnia Scale (AIS). The young (<35) female physicians showed significantly higher rates of suicidal thoughts, higher scores of PHQ and PPS. In the young female cohort, the AIS scores were significantly higher than of the other physicians. Conclusions - Mental health of physicians (sleep disorders, suicidal thoughts and psychosomatic symptoms) showed poorer results than the population data. BDI scores and the rate of suicidal attempts showed favourable trends. The next step in the physicians’ mental health researches is to investigate the most decisive risk factors, and to work out the prevention tools.

Unilateral thalamic infarction causing downward gaze palsy in a patient with uncorrected tetralogy of fallot: a case report

ANNUS Ádám, BENCSIK Krisztina, JÁRDÁNHÁZY Tamás, VÉCSEI László, KLIVÉNYI Péter

Introduction - Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease (CHD). Adults with surgically uncorrected forms of this condition are extremely rare, since operation is recommended in childhood to prevent cyanosis. Cyanotic CHD increases the risk of thromboembolic events. An endothelial dysfunction caused by chronic hypoxia and shear stress due to rheological alterations with a platelet dysfunction appear to be the explanation behind this finding. Paramedian thalamic infarction causing vertical gaze palsy without midbrain involvement is an infrequent finding. We report here a rare case of a patient with untreated TOF, who suffered a left-sided unilateral thalamic infarction presenting as downward gaze palsy and diplopia. Case presentation - A 44-year-old women complained of sudden onset diplopia and vertigo. Neurological examination revealed a downward gaze palsy with other symptoms related to a vertebrobasilar territory circulatory disturbance. The MRI scan revealed an acute infarction, 8 mm in diameter in the left medial thalamic region without midbrain involvement. Discussion - Adults with uncorrected forms of TOF are extremely uncommon, and descriptions of stroke in these patients are therefore rarities. We set out to give a concise survey of the literature regarding TOF patients with stroke. Conclusion - We present a rare case of unilateral thalamic infarction causing downward gaze palsy in an adult patient with uncorrected TOF. Cyanotic CHD is regarded as one of the risk factors of stroke. Besides other pathologic conditions, ischaemic stroke at an early age should raise the suspicion of a cardioembolic origin and, in rare cases, might result from cyanotic CHD.

[Smoking habits and predicting factors of smoking cessation among health care workers ]

SZELKÓ Olajosné Katalin, SIKET Ujváriné Adrienn, SÁRVÁRY Attila, ZRÍNYI Miklós

[The aim of the study: The aims of the study were to determine the prevalence of smoking and identify factors that predict smoking cessation motivation among health workers. Material and method: Cross-sectional, self-reported survey filled out by all healthcare workers of Jósa András Teaching Hospital. Statistical analyses were performed by chi-square analysis and Mann-Whitney tests. Results: Of all responses (N =1561), 29.9% reported actively smoking, 52.0% smoked between 11-20 cigarettes a day. A total of 20.4% had tried to quit smoking before. Those who would not participate in a smoking cessation program outweighed those who favored participation (43.2% vs. 35.6%). Significant relationships were found between the technique of smoking cessation and intent to quit smoking (χ2 = 7,73; p = 0,02) and between smoking cessation and stress induced smoking habits (r = 0,1; p = 0,12). Those not wanting to quit smoking appraised smoking as a social link to others (Z = -2.34; p = 0,02). Conclusion: Besides putting a stronger emphasis on smoking cessation and on negative health effects of smoking, nurse managers should promote working environments where improvement in stress management and collegial relationships will minimize the need for smoke related groups.. ]
