[During the assessment of blood donor candidates the physician considers two factors; first, whether the loss of 450 ml blood would be of any risk for them (e.g., because of hypotension) and second, whether they have any illness, current (seasonal allergy, antibiotic use, etc.) or chronic conditions (oncological or autoimmune disease, drug use, etc.) that may confer risk to the recipient. For the safety of blood preparations it is essential that the donors are dependable individuals who lead a lifestyle of low risk of getting infected (by HIV, hepatitis, etc.). Hungarian practice concerning donor qualification are generally stricter (e.g., because of the differences in the health care system, in the health culture) than the directive of the European Union. This implies that a number of donor candidates are temporarily or permanently disqualified. Following medical interventions (e.g., surgery, transfusion), environmental effects (e.g., radiation exposure) and recovery from diseases, however, the donor may again give blood after a certain period of time. Certain chronic diseases, if properly managed and if the patient is in perfect general condition, do not constitute a cause for exclusion either. General practicioners can greatly contribute to safe national blood supply by identifying and advising potential blood donors.]

[Awareness of Blood donation-related issues among paramedical professionals in Hungary]

RAJKI Veronika, HIRDI Henriett Éva, BALOGH Zoltán, MÉSZÁROS Judit

[Aim of the research: To assess the blood donation-related knowledge of paramedical professionals working in the fields of nursing and care-giving, emergency care, surgical care and obstetric care in Hungary. Sample and method: The anonymous, self-completion questionnaire used in the survey was based on the „Eurobarometer 41.0 (1995): Europeans and Blood” survey, which the authors supplemented with their own questions. The authors conducted a web-based survey. The survey took place between 15 July and 15 September 2012, among paramedical professionals in four different professional groups, using a convenience sampling method. The authors analysed the collected data with IBM SPSS Statistics 20 software and the Kingsoft Office Spreadsheet (2012) program, using a descriptive statistical method and chi square test. Results: The survey took place with the participation of 312 paramedical professionals. Based on the results of the survey it was established that all the professional groups displayed gaps in their knowledge regarding blood donation. 86.19% of respondents have a correct understanding of blood donation. No significant differences can be observed between the levels of knowledge in the individual professional groups. Conclusions: The results display some significant and some non-significant correlations, as well as stochastic relationships relating to the distribution within the submanifolds. In the interest of eliminating the gaps in knowledge that were revealed in respect of the individual issues, the authors highlight the need for further training of paramedical professionals regarding blood donation.]

[Hungarian health care professionals’ attitudes and habits regarding blood donation in different professional groups]

RAJKI Veronika, HIRDI Henriett Éva, BALOGH Zoltán, MÉSZÁROS Judit

[INTRODUCTION - We carried out a survey in Hungary among health care workers, we surveyed their habits in blood donation and their knowledge about the blood donation. METHODS - A cross-sectional study happened between 15th July and 15th Sep-tember in 2012 among the Adult nursing care-, Emergency care-, Surgical care-, and Maternity care professional groups, with convenience sampling statistical method (n=312). The data collection happened with a web-based, anonymous, self-administered questionnaire. For the edited electronic questionnaire we used some question from the “Eurobarometer 41.0 (1995): Europeans and the blood” survey. We analyzed the collected data with IBM SPSS Statistics 20 software and Kingsoft Office Spreadsheet (2012) program, using by descriptive statistical methods. RESULTS - The survey has occured with the participation of 312 health care workers. The blood donation activity of the health care workers in every professional groups was higher than the national average in a EU survey stated in 2009. 61.86% of the health care professionals give blood at least twice a year at different locations. The most common causes of the non-appearance from blood donation were the “other reasons”, “earlier forbidden from blood donation” and “lack of time”. We found differences in their view in each groups about refusing/authorizing blood transfusion, but these have no great importance. CONCLUSION - Regarding to our results we recommend to open the eyes to the need for common, aligned collaboration, and to the modifying the current competencies, to the betterment of the opportunities for further trainings in order to further increase of blood donation habits and attitudes. ]

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.
