The 3D MRA is a very good non-invasive investi­ gation of patients having brain tumors of diffe­rent types of the diseases of the intracranial vessels. This investigation can not give always enough infor­mation about every fine detail of the pathologic pro­cesses. Because of this fact in a lot of cases other methods have to be performed (for example DSA). lt is mostly necessary before operations. ln our pre­vious works we have investigated this problem in the cases of supratentorial tumors and vascular mal­formations. According to our practical experience the characteristics of the vascular malformations are the same in cases of the supra-and infratentorial processes, but on the other hand, they are not the same in cases of tumors. Because of that we have reviewed the MRl results of the posterior fossa tumors. lt has been an impor­tant point of view of our work if the MRA methodcould be able to substitute the DSA and generally any kind of information could be expected from this method in these cases.

Correlation of clinical and molecular genetic findings in malignant brain stem tumors

V. K. Ammon, U. Sure, DN Louis, V. Deimling A.

Brain stem gliomas are rare, predominantly pediatric tumours. Histologically, they are comparable to adult supratentorial astrocytomas. Most of the pediatric brain stem tumours were classified as low-grade astrocytoma (WHO II), anaplastic astrocytoma (WHO III) or glioblastoma multiforme (GBM, WHO IV). Survival of patients with malignant brain stem gliomas as WHO grade III and IV rarely exceeds more than two years. Recently developed molecular genetic techniques gave new insights in tumour biology. Oncogenes and tumour suppressor genes are genetic alterations which can cause tumorous transformation and furthermore malignant progression. Molecular genetic studies of malignant brain stem gliomas have rarely been investigated. Therefore, we set out to study 12 such tumours clinically and 2 by molecular biological methods.

Different autoregulatory responses in the cerebellar cortex, neocortex and subcortical gray matter of the rat to systemic hypo- and hypertension

BALÁZS István, BARZÓ Pál, DÓCZI Tamás, PÓRSZÁSZ Róbert, SZOLCSÁNYI János

Cerebral autoregulation was investigated in the cerebral and cerebellar cortex, and subcortical gray matter (caudate nucleus) of the rat by means of Laser-Doppler flowmetry. As the vascular architecture of the basal ganglia, the cerebral cortex and the cerebellar cortex have substantial geometrical, onto genetical and pathological differences (3), we tested the working hypothesis that autoregulation of the blood supply to these areas may also be different. Laser-Doppler flowmetry has an ideal time resolution, and it enables analysis of flow-pressure curves (1, 2). The dependency of autoregulation on the rate of change in systemic blood pressure (SABP) in all three regions were confirmed. Control of CBF was significantly different in the subcortical gray matter and the neocortex. Interestingly, no autoregulatory capacity of the cerebellar vasculature was found.

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

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.

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[Comparative analysis of the full and shortened versions of the Oldenburg Burnout Inventory]

ÁDÁM Szilvia, DOMBRÁDI Viktor, MÉSZÁROS Veronika, BÁNYAI Gábor, NISTOR Anikó, BÍRÓ Klára

[Background – The two free-to-use versions of the Oldenburg Burnout Inventory (OLBI) have been increasingly utilised to assess the prevalence of burnout among human service workers. The OLBI has been developed to overcome some of the psychometric and conceptual limitations of the Maslach Burnout Inventory, the gold standard of burnout measures. There is a lack of data on the structural validity of the Mini Oldenburg Burnout Inventory and the Oldenburg Burnout Inventory in Hungary. Purpose – To assess the structural validity of the Hungarian versions of the Oldenburg Burnout Inventory and the Mini-Oldenburg Burnout Inventory. Methods – We enrolled 564 participants (196 healthcare workers, 104 nurses and 264 clinicians) in three cross-sectional surveys. In our analysis we assessed the construct validity of the instruments using confirmatory factor analysis and internal consistency using coefficient Cronbach’s α. Results – We confirmed the two-dimensional structure (exhaustion and disengagement) of the Mini-Oldenburg Inventory and a shortened version of the Oldenburg Burnout Inventory Internal consistency coefficient confirmed the reliability of the instruments. The burnout appeared more than a 50 percent of the participants in every subsample. The prevalence of exhaustion was above 54.5% in each of the subsamples and the proportion of disengaged clinicians was particularly high (92%). Conclusions – Our findings provide support for the construct validity and reliability of the Hungarian versions of the Mini-Oldenburg Burnout Inventory and a shortened version of the Oldenburg Burnout Inventory in the assessment of burnout among clinicians and nurses in Hungary.]

[Tension type headache and its treatment possibilities]

ERTSEY Csaba, MAGYAR Máté, GYÜRE Tamás, BALOGH Eszter, BOZSIK György

[Tension type headache, the most common type of primary headaches, affects approximately 80% of the population. Mainly because of its high prevalence, the socio-economic consequences of tension type headache are significant. The pain in tension type headache is usually bilateral, mild to moderate, is of a pressing or tightening quality, and is not accompanied by other symptoms. Patients with frequent or daily occurrence of tension type headache may experience significant distress because of the condition. The two main therapeutic avenues of tension type headache are acute and prophylactic treatment. Simple or combined analgesics are the mainstay of acute treatment. Prophylactic treatment is needed in case of attacks that are frequent and/or difficult to treat. The first drugs of choice as preventatives of tension type headache are tricyclic antidepressants, with a special focus on amitriptyline, the efficacy of which having been documented in multiple double-blind, placebo-controlled studies. Among other antidepressants, the efficacy of mirtazapine and venlafaxine has been documented. There is weaker evidence about the efficacy of gabapentine, topiramate, and tizanidin. Non-pharmacological prophylactic methods of tension type headache with a documented efficacy include certain types of psychotherapy and acupuncture. ]
