[Personalized medicine and healthcare: where are we now, where should we go?]

The authors of this manuscript are representatives of different subdisciplines of medicine, all of them are experienced researchers. As of their origin, they are practicing doctors from the primary care and from the clinical/hospital setting, diagnostics experts, researchers from healthcare management, health economics, representatives of patients' rights and patient organizations. They are all devoted to the implementation of personalized medicine and personalized healthcare in Hungary. The current manuscript - also meant to be a keynote message provoking further discussion in the medical community - is devoted to correcting for two false ideas. One is that personalized medicine is not yet ready for practical applications, it is merely a research area of futurologists. The other false idea is that only (or mainly) the lack of financial resources hinders the introduction of personalized healthcare in Hungary. Orv Hetil. 2023; 164(6): 202-209.

[Anoxic myocardial lesions in man, developed during extracorporeal circulation, studied by electron microscopy]

Anoxemic changes of the myocardium were examined at 20 patients operated on in extracorporal circulation. At a mild degree hypothermia (30 degrees C) morphological changes appear after a 20 minutes period of anoxaemia. Damage to the myocard of irreversible character could be revealed after an anoxaemic period of 43--55 minutes. An intermitting perfusion of the coronary arteries delayes the formation of the lesions, although in cases of ligation of the aorta for 90 minutes severe mitochondrial changes and deformation of cells were seen. The best method for protecting the myocard is an isotherm perfusion of the coronary arteries. Clinical and laboratory findings show that necrosis of the myocard has a focal character and may play a part in formation of postoperative lesions.
