[ISOTOPE BASED CARDIAC DIAGNOSTICS - POSSIBILITIES IN NUCLEAR CARDIOLOGY]

BALOGH Ildikó

[Methods of nuclear cardiology have been applied for several decades and there is continuous development in this area. The most commonly used modality is the myocardial perfusion scintigraphy (MPS). During stress MPS, the presence and the severity of ischaemic heart disease (IHD) can be detected. Resting MPS can show a freshly developing acut myocardial infarction (AMI) immediately, but new and old infarcted myocardial areas can not be distinguished by this method. Using SPECT (single photon emission tomography) examination and quantitative analysis can improve the accuracy of MPS. With gated SPECT we can analyse both the perfusion and the function of left ventricle. To examine the function of left and right ventricle the “gold standard” non-invasive method is MUGA (multiple gated acquisition) of blood pool scintigraphy. After only a few hours of the onset of AMI we can detect it with the socalled infarct avid scintigraphy using radiopharmaceuticals which accumulate in affected area. Following an AMI it is essential to differentiate among high and low risk patients for revascularisation treatment, therefore distinguishing the viable (hibernating) and non-viable (necrotic) myocardium with imaging techniques is an important task. Preserved metabolism as the sign of viable myocardium can be detected both by SPECT (most accurately by thallium rest-redistribution scintigraphy) and PET (detecting glucose metabolism by F-18-FDG). Adrenerg receptor scintigraphy can show the sympathetic innervation: in the case of a transplanted heart it can detect the reinnervation and in the case of malignant ventricular tachyarrhythmias the risks and the severity of the illness.]

[CURRENT PRACTICE AND PROBLEMS IN RESUSCITATION]

DIÓSZEGHY Csaba

[Cardiopulmonary resuscitation is the progressive management of sudden cardiac arrest with the goal of restoring spontaneous circulation and preserve vital organ functions. Sudden cardiac death occuring out of hospital is still one of the major causes of death among otherwise healthy and young population however, approppriate management - certainly including resuscitation as the first step - might provide a reasonably good quality of life. Long term outcome of resuscitation is mainly determined by the links of the Chain of Survival, eg. early access, early CPR, early defibrillation and early advanced care. The aim of this review is to present the upto- date concepts for the best management of these survival links.]

[THE ROLE OF REGISTRY ANALYSIS IN THE FORMING OF THERAPEUTIC GUIDELINES IN RENAL TRANSPLANTATION]

PERNER Ferenc, HERCZEG Balázs, SZENOHRADSZKY Pál, ASZTALOS László, KALMÁR-NAGY Károly, JÁRAY Jenő

[The authors assess the two main outcomes of the immunosuppressive therapy after renal transplantation: graft and patient survival. According to their view, evidence from randomised clinical trials results can be well complemented by the several unique transplant registries and outcome research based upon these databases. The comparison of evidence from these two sources addresses the question of achievable outcome under ideal (controlled) versus real life conditions. Based on a systematic review of the relevant clinical trials and registries it can be stated, that in the case of some immunosuppressants (mycophenolate mofetil vs azathioprine, microemulsified cyclosporin vs cyclosporin and tacrolimus vs cyclosporin) the improvement in the intermediate outcome can lead to improved graft and patient survival, while in the case of other drugs no significant difference in hard endpoints were detected (tacrolimus vs microemulsified cyclosporin). Evidence on graft and patient survival differences could not be derived from traditional randomised clinical trials, only from transplant registries. For the sake of improved evidence based therapeutic guidelines in renal transplantation, authors call for further development of the Hungarian transplant registry.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[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.]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]
