[Prompt recognition and evaluation of hypertensive urgencies and emergencies can substantially decrease definitive target organ damage and mortality. Most frequent cause of sudden increase in blood pressure is stopping antihypertensive treatment. In hypertensive crises quickly acting parenteral drugs are of choice, while in urgencies orally administered ones might be sufficient. Cerebral and coronary hypoperfusion should be avoided therefore blood pressure must be decreased gradually.]

[Introduction: Erythropoietin (EPO) is a glycoprotein hormone, which is responsible for the proliferation and differentiation of erythroid cell lines. Since it is widely used as the treatment of renal anaemia, EPO-resistance is a common concern. Aims: We aimed to perform in vitro experiments to investigate a possible mechanism of EPO-hyporesponsiveness. Methods: We used a factor dependent erythroblast cell line (TF-1). Two independent observers calculated cell counts simultaneously on day 1; 2 and 3 in Bürker cell counting chambers. Colorimetric method was used to measure protein concentrations. Measurement of protein-bound para-, ortho- and meta-tyrosine was performed with reverse phase high performance liquid chromatography with fluorescence detection. We determined ERK and STAT5 activation using Western blot method. Results: In case of ortho- and meta-tyrosine pretreated cells time-dependent, EPOinduced proliferative activity was decreased compared to the 1.7 fold elevation of cell counts seen in para-tyrosine cultured cells. Protein concentration of ortho- and metatyrosine treated samples was significantly lower than control cells on the third day. Addition of para-tyrosine reclaimed EPO-sensitivity. Erythroblasts treated with orthoor meta-tyrosine contained lower concentrations of protein-bound para-tyrosine with higher ortho- and meta-tyrosine content. EPO dependent activation of ERK and STAT5 could be inhibited by ortho- or meta-tyrosine treatment. Conclusions: Elevated level of protein-bound ortho- and meta-tyrosine in erythroblasts can result in the pathological modification of intracellular signaling, leading to EPOhyporesponsiveness.]

[Authors studies the incidence of hypertensive patients with prediabetes - according to the IFG criteria - based on the 2005 Hungarian Hypertension registry (38849 subject) and on the „Live under 140/90” sub-program („Prevent it”) (23670 subject) database. The presences of diabetes patients were excluded. IFG incidence (from 5,6 to 7,1 mmol/l) was found between 13-18% of the adult population over 40 years. In men, the incidence was significantly higher. In individuals with IFG the BMI, waist circumference values were significantly higher than the average normal values and exceeded the danger zone. For women significantly higher values were found. These patients had higher total cholesterol and blood pressure values. After three months of intensive supervision, counseling, care over every 40 years age group - without medication - significantly decrease the fasting blood glucose values. They presented the international experiences of prediabetes.]

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.

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]
