[MR imaging has recently emerged for visual representation of blood vessel structures as well. With MR angiography (MRA), appropriate diagnosis can be established for a number of pathologies involving the arteries and veins. In this report, authors analyse the significance of MR and MRA examinations in the diagnostics of intracranial aneurysms of 87 cases, comparing these procedures with results obtained by digital subtraction angiography (DSA), which is regarded as the gold standard method. In 52 patients where surgical intervention was performed, intraoperative findings were used as control. MR - MR angiographic examination was very sensitive in detecting aneurysms larger than 3 mm (98%), the rate of depicting smaller aneurysms proved to be lower (56%), the overall sensitivity was 79%. MRA is an excellent non invasive diagnostic tool in the examination of intracranial aneurysms. The method can not replace catheter angiography completely but its application is justified and useful in many cases. Occasionally, aneurysms not seen on DSA can be depicted with MR angiography. ]

[Antibacterial therapy: 2000 balance and perspectives]

GRABER Hedvig

[Following a brief history of antibacterial therapy and evaluating the achievements and damages occurred, authors focus on today's problems and the following statements are made: Principles of treatment are clearly defined, however the choice of antibiotics may vary in time and in regions according to the differences in bacterial resistance. Antibacterials of the last decade (III-IV. generation fluoroquinolones, streptogramins, oxazolidinones, new vancomycine analogues) are intended to be effective against multiresistant Gram-positive cocci. Beside bacterial resistance, the most difficult therapeutic problems are the infections in the immunocompromised patients. The role of infection in the pathogenesis of certain diseases, e.g. ventricular/duodenal ulcer and probably atherosclerosis, has only recently been discovered; here new prospects may open for antibacterials. Data of the antibiotic utilization in Hungary show radical changes in the last years. Conclusion: the immense power of antibiotics still has its limits: to conquer bacterial disease successfully the intelligent combination of antibiosis, asepsis and immunization are required. ]

[Molecular mechanisms of cardiac hypertrophy and heart failure]

MIKALA Gábor, PETŐ Mónika, VÁLYI Nagy István, CSÁSZÁR Albert

[In this review, the most important molecular mechanisms leading to cardiac muscle hypertrophy and consequentially to heart failure are detailed. In numerous instances, understanding molecular mechanisms offers the possibility for pharmacotherapeutic intervention. First, trimeric G-proteins and their attached intracellular signaling pathways are introduced, with special emphasis on the pathways elucidated by transgenic animal models. In this area, there are several clinically effective drugs to influence cardiac hypertrophy, including ACE inhibitors, angiotensin receptor antagonists, as well as a- and B-adrenergic receptor blockers. Mitogen activated protein kinases participate later in the hypertrophic cascade. There are ongoing investigations on the potential therapeutic use of lipid-soluble statins these are indirect inhibitors of Ras-farnesylation. Altered cellular Ca2+-homeostasis is fundamental with respect to cardiac muscle hypertrophy and heart failure. The third part of this article investigates the role of the calcium/calmodulin dependent protein phosphatase called calcineurin in these processes. Administration of cyclosporin A or tacrolimus (both are inhibitors of calcineurin) may not be recommended in most forms of cardiac hypertrophy, however, in certain settings they may prove to be valuable therapeutic agents. One of the most serious, not yet properly addressed problem of late stage heart failure is the development of ventricular arrhythmias caused by repolarization abnormalities. Certain mechanisms of this phenomenon are highlighted with a special note on Nat-Cat exchange inhibitors as one of future therapeutic agents of much promise. ]

[The growth in digital media technology within the past decade has strengthened e-Learning’s position in education. Traditional teaching methods are changing: from teacher to moderator and passive learner to active learner. A pilot e-Learning course in MR angiography (MRA) has been undertaken with Hungarian radiographer participants. The e-Learning course consisted of three phases covering basic MRA physics and technical aspects, advanced MRA techniques and concluding with an assessment work. The promising results suggest that e-learning may be a feasable method for the continuing professional development of Hungarian radiographers.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.
