[Prevention of thrombotic complications in vascular interventional procedures]


[Procedures of vascular interventional radiology is linked inevitably a certain amount of risk of thrombotic complications, like intimal and vascular wall injuries, increased thrombotic risk caused by the catheter itself, etc. The first approach of thrombotic prevention was achieved by acetyl salicylic acid in case of peripheral arteries, this treatment was later replaced by long-term anticoagulation. Opportunities were provided by the recognition of risky blood characteristics in relation to thrombotic complications. Consequently, a well performed preparation and premedication of the patients could reasonably decrease the risk. The most important steps are the cessation of smoking, normalization of hemoconcentration and antithrombotic premedication. Better understanding of the nature of atherosclerotic progression led to the introduction of long-term fibrinolytic inhibition therapy. In the past decades beside patients with vascular stenosis, the oncology patients are also treated by different radiological interventions, like intraarterial chemotherapy and chemoembolization. The use of several-day-long infusion represent a new challenge, the treated vessels, the lumen and the surface of the catheter must be prevented of thrombosis. For this purpose a few suitable drugs can be applied with mild anticoagulant and fibrinolytic stimulating effect. We use the sodium pentosan polysulphate.]

[Comparison of the results of lung helical CT and lung scintigraphy in pulmonary embolism]

WENINGER Csaba, BODROGI Gabriella, BOROS Szilvia, SCHMIDT Erzsébet, UDVAROS Eszter, ZÁMBÓ Katalin

[INTRODUCTION - The frequency of the pulmonary embolism is high and the underdiagnosis or delayed recognition of the disease occurs. Recently the helical CT is used to detect pulmonary embolism. The authors compare the results of single-slice spiral thoracic CT and lung scan. PATIENTS AND METHODS - During one year period chest CT examination was performed in 49 patients due to the suspicion of pulmonary embolism, in 30 of them lung scan was also performed. RESULTS - The results of the two diagnostic methods were the same in 21 cases out 30 (in 13/21 cases both methods demonstrated embolism and 8/21 cases the findings were normal). In the remaining nine cases the findings were different. CONCLUSIONS - The lung CT examination is a rapid, non-invasive method to depict the central pulmonary embolism and small infarcts in non fresh cases. The negative result of perfusion lung scan can exclude the pulmonary embolism. If the lung scan demonstrates perfusion defect(s), it is necessary to perform another diagnostic tests (e.g. chest X-ray, ventillation scan). While the lung scan is a cheap, simple method with low radiation dose, it can play important role in the screening.]

[The possibilities of invasive radiological therapy of deep venous thrombosis and in vitro experimental examination of therapeutic factors affecting the treatment]


[INTRODUCTION - The first part of this paper is an overview on the possibilities of invasive radiology treatment of deep venous thrombosis. In the next part an in vitro experiment is described demonstrating the basics of mechanical and pharmaco-mechanical catheters applied in deep venous thrombosis. MATERIALS AND METHODS - The in vitro haemodinamic model of the iliocaval veins contained a thermostat and an engine responsable for pulsing circulation according to the venous system. We tested the chance of driftage of thrombus in different age according to the state of the collateral system. Thrombectomy was made by mechanical (Simpson-catheter) and pharmaco-mechanical (Pulsespray catheter) ways. The weight of the non-drifted thrombi was measured. RESULTS - All the 16 thrombus were flown while collateral system was closed and none of them were flown while the collateral system was open but the rate of their solubility was different. The efficacy of the thrombus-removal by Simpson catheter was better than by Pulse-spray catheter and fresh thrombus-fragments were more soluble than older ones. CONCLUSION - By this in vitro experiment we opened the way for using mechanical and pharmaco-mechanical catheters in deep venous thrombosis.]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]


[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]

[Association between cyclothymic affective temperament and hypertension]


[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.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Tracing trace elements in mental functions]

JANKA Zoltán

[Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de­mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area. ]
