[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.]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[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.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[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.]
