    Absztrakt: Egy 42 Ă©ves fĂ©rfi akut coronaria szindrĂłma okozta De Winter-fĂ©le EKG-jel miatt kerĂŒlt sĂŒrgƑssĂ©gi osztĂĄlyra. Az EKG nem megfelelƑ interpretĂĄciĂłja miatt csak hĂĄrom ĂłrĂĄval kĂ©sƑbb kerĂŒlt a katĂ©teres laboratĂłriumba. Addigra a hiperakut T-hullĂĄmok megszƱntek, a praecordialis ST-depressziĂł regrediĂĄlt, de a cardialis biomarkerek jelentƑs emelkedĂ©st mutattak. A coronarographia a bal elĂŒlsƑ leszĂĄllĂł coronaria proximĂĄlis thromboticus dissectiĂłjĂĄt mutatta, amely egy gyĂłgyszerkibocsĂĄtĂł sztenttel lett lefedve. A szerzƑk azĂ©rt ismertetik ezt az EKG-jelet, mert ilyen esetben – attĂłl fĂŒggetlenĂŒl, hogy nincs ST-szegmens-elevĂĄciĂł – a javasolhatĂł kezelĂ©s az azonnali coronariaintervenciĂł. Orv Hetil. 2019; 160(43): 1711–1713. | Abstract: A 42-year-old man is presented with acute coronary syndrome and De Winter ECG sign. The De Winter sign is a rare ECG manifestation of proximal LAD occlusion. The ECG sign was misinterpreted and the patient was transmitted to our percutan coronaria intervention centrum with 3 hours delay. The hyperacute T-waves and the precordial ST-depressions disappeared, but the biomarkers showed a marked elevation. Coronary angiography revealed LAD proximal thrombotic dissection treated with a drug-eluting stent. The authors suggest that in patients with this ECG pattern the immediate coronary intervention is the best treatment. Orv Hetil. 2019; 160(43): 1711–1713

    Absztrakt: A laikusok oktatĂĄsa sorĂĄn gyakran hangsĂșlyozzuk, milyen fontos a szĂ­vizominfarktus korai felismerĂ©se Ă©s a beteg mielƑbbi speciĂĄlis centrumba törtĂ©nƑ szĂĄllĂ­tĂĄsa. A tĂ­pusos panaszok mellett – ilyenek az erƑs mellkasi nyomĂĄs, szorĂ­tĂł Ă©rzĂ©s, bal vĂĄllba, lapockĂĄba vagy ĂĄllkapocsba kisugĂĄrzĂł fĂĄjdalom – gyakran elƑfordul, hogy extracardialis tĂŒnetegyĂŒtteskĂ©nt jelentkezik az angina. Ezen utĂłbbiak leginkĂĄbb gastrointestinalis tĂŒneteknek imponĂĄlnak, Ă©s gyakran mĂ©g a tapasztaltabb orvosokat is fĂ©lrevezethetik a diagnĂłzis felĂĄllĂ­tĂĄsakor. Egy 83 Ă©ves, idƑs nƑbeteg esetĂ©t ismertetjĂŒk, aki bĂĄr Ă©vtizedek Ăłta ismert coronariabetegsĂ©gben szenved, 2015 decembere Ăłta egy egĂ©szen Ășj tĂŒnetet produkĂĄl angina pectorisban, ez pedig a hangos, visszafojthatatlan böfögĂ©s. Nyolc hĂłnap alatt nĂ©gy alkalommal jelentkezett böfögĂ©ssel kezdƑdƑ, majd mellkasi fĂĄjdalommal is tĂĄrsulĂł panasza, Ă©s bĂĄr kezdetben a böfögĂ©snek nem tulajdonĂ­tottunk kĂŒlönösebb jelentƑsĂ©get, mind a nĂ©gy alkalommal igazolĂłdott coronariaintervenciĂłt igĂ©nylƑ occlusio. Orv. Hetil., 2017, 158(5), 183–186. | Abstract: While educating non-medical personnel on acute coronary syndrome we often emphasize the importance of early recognition and urgent transfer to acute cardiac center of patients with acute myocardial infarction. Aside from typical symptoms of chest tightness and pain radiating to shoulder, arm and jaw, angina often presents with atypical, non-cardiac complaints. These symptoms, often suggesting gastrointestinal problems, can sometimes mislead even the most experienced physicians. We would like to present the case of an 83-year-old woman with several decades long history of ischaemic heart disease, who recently developed a new anginal symptom: lound, uncontrollable belching. Within the past eight months she was admitted four times with complaints of belching followed by chest pain. Even though initially it was thought as an incidental finding, in all four cases she had proven coronary occlusion requiring cardiac intervention. Orv. Hetil., 2017, 158(5), 183–186

    The developmental impact of prenatal stress, prenatal dexamethasone and postnatal social stress on physiology, behaviour and neuroanatomy of primate offspring: studies in rhesus macaque and common marmoset

    RATIONALE: Exposure of the immature mammalian brain to stress factors, including stress levels of glucocorticoids, either prenatally or postnatally, is regarded as a major regulatory factor in short- and long-term brain function and, in human, as a major aetiological factor in neuropsychiatric disorders. Experimental human studies are not feasible and animal studies are required to demonstrate causality and elucidate mechanisms. A number of studies have been conducted and reviewed in rodents but there are relatively few studies in primates. OBJECTIVES: Here we present an overview of our published studies and some original data on the effects of: (1) prenatal stress on hypothalamic-pituitary-adrenal (HPA) re/activity and hippocampus neuroanatomy in juvenile-adolescent rhesus macaques; (2) prenatal dexamethasone (DEX) on HPA activity, behaviour and prefrontal cortex neuroanatomy in infant-adolescent common marmosets; (3) postnatal daily parental separation stress on HPA re/activity, behaviour, sleep and hippocampus and prefrontal cortex neuroanatomy in infant-adolescent common marmoset. RESULTS: Prenatal stress increased basal cortisol levels and reduced neurogenesis in macaque. Prenatal DEX was without effect on HPA activity and reduced social play and skilled motor behaviour in marmoset. Postnatal social stress increased basal cortisol levels, reduced social play, increased awakening and reduced hippocampal glucocorticoid and mineralocorticoid receptor expression in marmoset. CONCLUSIONS: Perinatal stress-related environmental events exert short- and long-term effects on HPA function, behaviour and brain status in rhesus macaque and common marmoset. The mechanisms mediating the enduring effects remain to be elucidated, with candidates including increased basal HPA function and epigenetic programming

    Seizure logging: A new approach to synchronized cable-free EEG and video recordings of seizure activity in mice

    Full text link
    We describe a new cable-free, non-telemetric method for synchronized electrophysiological and videorecordings of seizure activity in freely moving mice. The electrophysiological recordings were made bya head-mounted 4-channel data-logging device, allowing the mouse to move freely in its cage, and evento be moved from cage to cage under ongoing recording. Seizures were studied in Synapsin I/II doubleknock-out (SynDKO) mice, a genetically engineered mouse line that shows seizures upon daily handlingprocedures such as tail lifting during cage changes, much in resemblance to the more studied El mouse. The ability to elicit seizures through daily handling in SynDKO mice undergoing electrophysiological recording is a significant improvement in comparison to the traditional cable-based set-up. Furthermore, with its four channels and a sample rate of up to 500 Hz, the data-logging device opens for more varied electrophysiological studies than other available cable-free systems
