[This review summarizes the diagnostic spectrum, ways of application and methodological difficulties of multislice computed tomographic (MSCT) coronary angiography. The non-invasive assessment of cardiac and coronary anatomy is now possible with computed tomographic coronary angiography using the modern 16 to 64-slice technology. This technique finds its main use today in the screening of patients with moderate probability of having coronary artery disease (atypical chest pain). Its negative predictive value varies between 97% and 99%, thus, a negative result of this non-invasive outpatient procedure can reduce the possibility of coronary artery disease to the minimum. Other important diagnostic applications include the follow-up of patients with coronary artery bypass, accurate diagnosis of coronary artery anomalies, and the simultaneous examination of the heart and great vessels. The future development of the technique is directed to coronary plaque characterization, particularly the detection of vulnerable plaques. The radiation exposure is relatively low (7-13 mSv), comparable with that of invasive coronary angiography.]

[ANTIHYPERTENSIVE THERAPY IN VIEW OF RECENT CLINICAL STUDIES]

ALFÖLDI Sándor

[Different antihypertensive agents, while having the same blood pressure lowering effect, will have significantly and clinically important different impact on the serum levels of glucose, lipids, insulin, potassium, creatinine, as well as on albumin excretion, heart rate, body weight, central pressure, various hypertensive target organ damages, and, in particular, 24-hour blood pressure dinamics. There is agreement in that the main benefits of first-line antihypertensive agents are related to the lowering of blood pressure itself. Some other drugs, however, have shown preventive and protective cardiovascular properties in certain patient groups, independent of their blood pressure lowering effect as measured traditionally.]

[BENEFICIAL EFFECT OF INSULIN DETEMIR ON THE BODY WEIGHT OF DIABETICS]

BECHER Péter

[Detemir is the newest base insulin analogue. In phase III trials and the PREDICTIVE study, the use of insulin detemir in various treatment regimens (basal-bolus or in combination with an oral antidiabetic) did not lead to weight gain in either types of diabetes, in contrast to what is usually observed with insulin therapy. Similar results were obtained when neutral protamine Hagedorn insulin or glargine were replaced by detemir, or insulin-naive patients received detemir as a new therapeutic regime. The mechanism of the beneficial effect on body weight is not clear yet. It may be related to the reduction in the number of hypoglycaemic episodes. It may also be associated with a stronger action of detemir on hepatocytes compared to peripheral tissues due to its acylation, which results in an effective suppression of hepatic glucose output without promoting lipogenesis in the adipocytes. Detemir reaches the insulin receptors of the hypothalamus faster than regular insulin, therefore, satiety develops in a shorter time. These hypotheses still require further studies.]

[INFLAMMATORY BOWEL DISEASE IN CHILDREN]

BODÁNSZKY Hedvig, VERES Gábor

[The term inflammatory bowel disease includes two similar, but distinct intestinal diseases so far of unknown ethiology - ulcerative colitis and Crohn’s disease. They used to be considered diseases of young adults, but in recent decades they have become more common among children, with characteristics different from those in adults. In the past they were considered severe, incurable diseases, but today, owing to modern nutrition, medical and surgical treatment, both diseases have became well manageable, even though complete recovery can not yet be expected.]

[The radiohygienic aspects of the interventional radiology]

PELLET Sándor, GICZI Ferenc, GÁSPÁRDY Géza, TEMESI Alfréda

[Interventional radiology is a relatively new and very rapidly developing cost-effective branch of radiology. Its aim to help or to replace surgical procedures and interventions in many cases are life saving, which are performed by imaging modality control (most commonly angiography or fluoroscopy). During interventional radiological procedures the exposure of staff and patients is usually higher, than in conventional radiography or fluoroscopy. Deterministic effects may also occur. The dosimetry can be carried out by film dosimetry, thermoluminescent dosimetry, DAP meters, semiconductor detectors and personal electronic dosimeter. The basis of reduction of radiation exposure is the radiation protection training. An important rule is that reduction of patient exposure is connected with reduction of staff exposure. With the use of appropriate tools and training the most injuries are avoidable.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

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

SZAUDER Ipoly

[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.]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]

FARSANG Csaba

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]
