De Winter's ECG: Not your usual STEMI.

We report a 39-year-old male who presented with severe chest pain and diaphoresis who suffered from pulseless polymorphic ventricular tachycardia en route to the hospital. His initial electrocardiogram showed De Winter's Pattern (dWP). Coronary angiography revealed 100% thrombotic ostial occlusion of the left anterior descending artery.

Prolonged esophageal acid exposures induce synaptic downscaling of cortical membrane AMPA receptor subunits in rats.

Background: We recently reported the involvement of AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptor subunit upregulation and phosphorylation in the rostral cingulate cortex (rCC) as the underlying mechanism of acute esophageal acid-induced cortical sensitization. Based on these findings, we proposed to investigate whether prolonged esophageal acid exposures in rats exhibit homeostatic synaptic scaling through downregulation of AMPA receptor expression in rCC neurons. We intended to study further whether this compensatory mechanism is impaired when rats are pre-exposed to repeated esophageal acid exposures neonatally during neuronal development.

Extrahippocampal integrity in temporal lobe epilepsy and cognition: thalamus and executive functioning.

Chronic temporal lobe epilepsy (TLE) is characterized by the presence of extra-hippocampal brain abnormality and cognitive impairment in both memory and nonmemory domains. However, the link between structural integrity and cognition has not frequently been studied. Forty-six patients with TLE and 61 age-matched controls were studied to determine the predictive relationship between baseline thalamic volume and performance on measures of executive functioning evaluated 4 years later.

Thalamofrontal circuitry and executive dysfunction in recent-onset juvenile myoclonic epilepsy.

Purpose: Thalamofrontal abnormalities have been identified in chronic primary generalized epilepsy, specifically in juvenile myoclonic epilepsy (JME). These regions also underlie executive functioning, although their relationship has yet to be examined in JME. This study examined the relationship between thalamic and frontal volumes and executive function in recent-onset JME compared to healthy control subjects and recent-onset benign childhood epilepsy with centrotemporal spikes (BCECTS), a syndrome not typically associated with thalamocortical or executive dysfunction.
