EKG-gyöngyszem: tranziens De Winter-jel = ECG pearl: transient De Winter sign
Absztrakt:
Egy 42 éves férfi akut coronaria szindróma okozta De Winter-féle EKG-jel miatt
kerĂŒlt sĂŒrgĆssĂ©gi osztĂĄlyra. Az EKG nem megfelelĆ interpretĂĄciĂłja miatt csak
hĂĄrom ĂłrĂĄval kĂ©sĆbb kerĂŒlt a katĂ©teres laboratĂłriumba. Addigra a hiperakut
T-hullåmok megszƱntek, a praecordialis ST-depresszió regrediålt, de a cardialis
biomarkerek jelentĆs emelkedĂ©st mutattak. A coronarographia a bal elĂŒlsĆ
leszĂĄllĂł coronaria proximĂĄlis thromboticus dissectiĂłjĂĄt mutatta, amely egy
gyĂłgyszerkibocsĂĄtĂł sztenttel lett lefedve. A szerzĆk azĂ©rt ismertetik ezt az
EKG-jelet, mert ilyen esetben â attĂłl fĂŒggetlenĂŒl, hogy nincs
ST-szegmens-elevĂĄciĂł â a javasolhatĂł kezelĂ©s az azonnali coronariaintervenciĂł.

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

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.

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
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
