[Gastrointestinal stromal tumor]

GONDA Gábor

[Gastrointestinal stromal tumors were subject of much controversy in the last decades. This type of tumors was delineated from the leiomyoma - leiomyosarcoma group. GISTs show variable histological picture, moreover, they are capable of dual (neurogen and myogen) differentiation as it is proved by immunohistochemical and ultrastructural studies. These tumors have relatively good prognosis, only 10-30% of them is malignant, although it is difficult to predict their behaviour in a given case. The most reliable signs of malignancy - cytological pleoimorphism, high mitotic activity, proliferation index above 10 %, and aneuploid DNA content - are generally accepted. The treatment of choice is excision, but not enucleation. Radical surgery is not necessary, since lymph node metastasis is exceptionally rare. Further investigations revealed electronmicroscopical and immunohistochemical (CD 34, CD 117) similarities of tumor cells and interstitial cells of Cajal (ICC) located in the wall of the bowel. The results of these investigations led to the theory that cells of GIST and ICCs are of the same stem cell origin. Molecular genetic studies are also of great help in the differential diagnosis and in predicting the prognosis of GISTs. Mutations in the c-kit gene can not be detected in leiomyomas, so they are thougt to be specific for GISTs. Mutation of exon 11. of chromosome 4. is observed only in malignant GISTs.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[On nursing in a different way - What are we talking about? ]

SÖVÉNYI Ferencné, PERKÓ Magdolna, FEDINECZNÉ Vittay Katalin

[Using an uncustomary approach to nursing history, authors review the intensive development process in the 1990s that resulted in the transition of nursing from an occupation to profession in Hungary. An occupa­tion attains professional status if its practitio­ners have access to education and training of a considerable duration, it has independent professional organisation, an ethical code of its own and is regulated by law. The article addresses these factors discussing at length the history and development of nurs­ing education and training in Hungary, subsequently it describes the process arching from practical nursing to the appearance of nursing science, an intrinsic part of which was the birth of a scientific nursing journal “Nővér”. The relevant and effective legislation on nursing and nursing practice is re­viewed comprehensively and the efforts to establish professional nursing organisations are described. It is maintained that framework conditions had to be established as a necessary precondition for nursing to professionalise itself on its own and become a vocation highly regarded by society. ]
