[Metoprolol treatment in dialated cardiomyopathy]

DÉKÁNY Miklós, NYOLCAS Noémi, FIÓK János, VÁNDOR László, SEREG Mátyás, BALOGH Ildikó

[Authors applied metoprolol for treating heart failure in with dilated cardiomyopathy. Patients were given digitalis, diuretics as well as ACE-inhibitor and vasodilator drugs. The grade of heart failure was according to NYHA classification in the mean 2.5 class. For assessing the effect of metoprolol clinical variables and results of non-invasive tests were evaluated and compared in 3 consecutive periods: 1) before starting metoprolol, 2) 2–4 weeks after reaching its definitive dose (short-term effect), 3) 3-6 months later (medium-term effect). Early intolerance appeared in 3 patients; signi ficant progression of heart failure in 2 and hypotension causing complaints in 1. Evaluating the actually treated 17 patients clinical signs of heart failure (NYHA class) decreased, left ventricular ejection fraction improved, though not significantly in case of every considered variables, left atrial filling pressure decreased, exercise capacity did not alter, rate-pressure product decreased at rest and at low level of exercise as well. The authors stress the significance of "up-regulation" of myocardial beta-1 receptors in the reduction of myocardial toxic catecholamin effect and myocardial oxygen demand as well as in the increase of myocardial blood supply. Referring to the data of the respective literature and to their own experiences the authors suggest metoprolol treatment in cases of dilated cardiomyopathy, where previus therapy did not prove to be efficient.]

[Role of oxygen derived free radicals during myocardial reperfusion]

KÓNYA László , FEHÉR János, JUHÁSZ Nagy Sándor

[Oxygen derived free radicals are now considered to be important contributors to tissue (myocardium) injury associated with ischemia and reperfusion. Normaly the tissue concentration of these toxic intermediate products of oxygen is strietly limited, but production of oxygen free radicals overwhelming the capacity of the tissue elimination may cause serious damage. Thus reperfusion has it's own danger with the extension of the injury produced by the ischemia alone. Several experi mental studies have shown that different free radical scavengers can reduce the post-ischemic tissue injury, however, there are contradictory results and unresolved problems. Further investigation is necessary to establish the relevance of oxygen free radical mediated myocardial injury and the effective antioxidant treatment. ]

[Autoimmunity and the network of the antibody-forming cells: the "immunological homunculus"]

UHER Ferenc

[Frank M. Burnet's clonal selection theory declares the deletion and/or anergy of self-reactive clones to be the fundamental mechanism responsible for self tolerance. There is ample evidence, however, that all healthy individuals have lymphocytes and , natural” antibodies that recognize self structures. In the 1970s, Niels K. Jerne postulated the network theory. It is based on the idea that the idiotype, the region of an immunoglobulin that is unique because it comprises the antigen-binding portion of the molecule, can act as both antigen and antibody within the same individual. Network theory views the immune system as a single, highly interconnected system, through idiotypes, a web of V domains. Antonio Coutinho adressed this problem and divided the repertoire of the B lymphocytes into two parts. He suggested that a set of naturally activated cells and the immunoglobulins they secrete, is reflected in the autonomous immune activities of the self-related network as the central immune system. In contrast, immune responses to external antigens are essentially allonomous clonal activities of another set of resting, rapidly turning over lymphocytes that follow the predictions of the clonal selection theory, making up the peripheral part of the system. Finally, Irun R. Cohen suggested that some, perhaps all, major autoantigens are indeed dominant because each one of them is encoded in the organizational structure of the immune system. This picture was termed the immunological homunculus by its analogy to the picture of the body encoded in the central nervous system. ]

[Modern therapy of intracerebral and subarachnoidal hemorrhages]

LEEL-ŐSSZY Lóránt

[The frequency of the intracerebral hemorrhages among the strokes is most commonly quoted around 10 percent. The rupture of an intracranial aneurysm is often complicated with subarachnoideal hemorrhage as well as with intracerebral hematoma therefore this latter type of intraparenchymal hemorrhage may also be discussed in this topic. The modern imaging procedures (Computed to mography, Nuclear magnetic resonance) are of crucial importance in the urgent and exact diagnosis of intracranial hemorrhages. The first essential step in the diagnosis of stroke is to distinguish the ischemic lesion from the hemorrhage by means of CT. When an intra cerebral hemorrhage threatens life and the patient's condition is relatively good there must be an urgent decision considering the choice between medical therapy or surgical intervention. Although clearcut indications for surgery are now available, the clinical and computed tomographic guidelines play indi vidually an important role in the final decision. The individual judgment is always desirable in every case of intracerebral hemorrhage as well as in the surgical intrvention of intracranial aneurysm during the acute phase (two days).]

[What makes youth happy today? Relationships between religion, spirituality and mental well-being among high school students]

PIKÓ Bettina, KOVÁCS Eszter, KRISTON Pálma

[INTRODUCTION - Studies suggest that traditional religiosity is more and more neglected among adolescents, however, not implying to the lack of religiousness or spirituality. Religion/spirituality is still a significant protective factor. Therefore, the main goal of the present paper was to analyze indicators of mental well-being in a sample of high school students in light of religious/spiritual variables. METHODS - The data collection of the questionnaire survey (2010) was going on among 656 high school students in Sze­- ged (age range between 14-21 years, mean=16.5 years, S.D.=1.5 years of age, 49.1% of the sample was female). Depressive symptomatology, satisfaction with life and optimism were dependent variables and indicators of spirituality/religiosity were the independent ones. Beyond descriptive statistics, correlation and multiple regression analyses (stepwise method) were applied in the calculations. RESULTS - Our results show that for today’s youth happiness is primarily associated with their existential well-being: those who see a meaning in life, who have goals in life and believe that they are able to see through and understand life events, tend to be more satisfied with life, more optimistic and less depressed. Besides, spiritual belief may also contribute to life satisfaction whereas importance of religiosity may be a protective factor in the case of depression. CONCLUSIONS - Based on these results we may conclude that existential well-being (that is, finding a meaning in life) is a prominent spiritual variable. Data also suggest, however, that youth’s mental well-being only partially comes from religiosity, mostly it stems from other resources. More research is needed to detect this. All in all, as it appears that youth do need a belief in a meaning in life, similar to other age groups.]

[Development of anticoagulation in the past two decades]

SAS Géza

[In the past two decades we have witnessed a gradually increasing significance of both prophylactic and therapeutic anticoagulation. The importance of thromboprophylaxis has become widely accepted in the course of surgical interventions and in various other fields of medicine, too. The introduction of low molecular weight heparins was a milestone in this respect. The need for long-term anticoagulation has become a common problem. The various recent aspects and topics of anticoagulation have been described in the current Hungarian medical literature, therefore, I focus on two general problems of medicine of our days from the aspects of our subject. The evaluation of information on the new, direct-acting inhibitors (anti-IIa and anti- Xa),and their high price present great difficulies, especially in the case of long-term anticoagulation therapy. Clinical data and experiences have been collected from patients who are greatly different from the majority of patients in the real world. The lack of antidote may also be a serious problem in case of these new drugs, as urgent neutralization might be necessary, for example in case of serious bleeding, accidents etc. Today, cost-effectiveness of medical interventions and drugs has become a major aspect, therefore, the high price of new anticoagulants might prevent their use in the clinical practice. Despite the optimistic expectations regarding new anticoagulants, at present we have to strive to treat our patients with the currently available, effective but affordable drugs, widening and improving their use.]
