Acute Subarachnoid Hemorrhage and Cardiac Abnormalities: Takotsubo Cardiomyopathy or Neurogenic Stunned Myocardium? a case report

Abstract Introduction Cardiac abnormalities can be seen with subarachnoid hemorrhage. To date, there have been isolated case reports of transient left ventricular apical ballooning cardiomyopathy, also known as Takotsubo cardiomyopathy in patients suffering from subarachnoid hemorrhage. Case presentation An adult female was brought to the emergency department with somnolence. A 3 × 3 mm ruptured basilar aneurysm was found and successfully embolized. Two days after the patient developed acute heart failure. Troponin-I was elevated to 4.2 (normal \u3c0.4). On ECG, new symmetric T wave inversion in V3, V4, V5 with prolonged QT were evident. Transthoracic echocardiogram showed severe systolic dysfunction with an ejection fraction of 20% and akinetic apex along with the distal left ventricular segments, consistent with Takotsubo cardiomyopathy. Myocardial contrast echocardiography showed a decrease in capillary blood flow and volume in the akinetic areas with delayed contrast replenishment, sparing the basal segments. A repeat study 2 weeks later showed near normalization of the perfusion parameters. The patient improved with medical management. A repeat echocardiogram, a month later revealed an ejection fraction of 45% with no identifiable wall motion abnormality. Conclusion Our case, as well as others reported previously, supports the diagnosis of Takotsubo cardiomyopathy in patients with Subarachnoid Hemorrhage who fulfill the clinical and imaging description of this syndrome

Apocrine carcinoma of the face in a 62-year-old Asian man

Apocrine carcinoma (AC) is a rare tumor with heterogeneous presentation. The disease has a highly morbid course and little is known about it. We present an otherwise healthy, 62- year-old Asian male who originally presented with chronic swelling of his left eyelid associated with excessive tears and diminished vision was diagnosed with AC. AC is often challenging to diagnose, yet it is critical to do so as early diagnosis and treatment can maximize patient survival

Cognitive impairment induced by permanent bilateral common carotid occlusion exacerbates depression-related behavioral, biochemical, immunological and neuronal markers

Item does not contain fulltextThere is a strong link between cognitive impairment and depression, but up to date it is not clear whether cognitive impairment is 'cause' or 'consequence' of depression. Therefore, we here examined the effect of cognitive impairment induced by permanent occlusion of common carotid arteries, a model known as two-vessel occlusion (2VO), on chronic unpredictable stress (CUS)-induced depression-related markers in rats. Male Sprague-Dawley rats underwent 2VO or sham surgery. Sixty days after the surgery, the cognitive function of the rats was tested using the radial arm maze task measuring working and reference memory. Subsequently, the animals were randomly assigned to undergo 21 days of CUS or to stay non-stressed. One week after the last stressor, psychomotor retardation, a feature of depression-like behavior, was assessed using the forced swim test (FST) by measuring time spent on immobility. Plasma amino acid (glutamine, glutamate and glycine) and serum pro-inflammatory cytokine (interleukin 6) levels, and hippocampus CA1 neuronal damage were measured 24h after FST exposure. Results show that 2VO increased immobility in the FST only when rats had been exposed to CUS. In addition, 2VO surgery intensified the effect of CUS on IL-6, glutamate and glycine levels and increased CA1 hippocampal damage. In conclusion, our findings show that cognitive impairment may predispose to depression by intensifying the effect of stress on depression-related behavioral, biochemical, immunological and neuronal markers
