A host of studies on the cardiac innervation have found a complex link known as cardiac autonomic nervous system (CANS), connecting extracardiac nerves, intracardiac ganglia, and myocardial cells. Now it is well known that CANS plays a critical role in regulating the functions of the heart and its imbalance is regarded as one of the major causes of cardiac arrhythmias. With the development of medical technology and the advancement of ideas, several novel therapies of arrhythmias through modulati...
Permanent Memory Deficits with Normal MRI Following Heat Stroke after Physical Activity and Sauna

Heat stroke is the result of high heat stress and determines multi-organ dysfunction with predominant encephalopathy. Heat stroke only rarely leads to permanent neurologic deficits with a propensity to cerebellar dysfunction while memory disorders are very unusual. We report a unique case of a patient who suffered from a heat stroke after strenuous physical activity and sauna, resulting in persistent memory deficit with normal acute and follow-up normal MRI. Neuropsychological assessment suggest...
Effect of Elasticity on Flow Characteristics Inside Intracranial Aneurysms

Many medical and bioengineering researchers have investigated flow behavior inside intracranial aneurysms using computational fluid dynamics. The majority of these studies assume to be rigid wall, but blood flows through a deformable elastic vessel. A few researchers have tried to simulate using fluid-structure interaction because an elastic wall implicates the decrease of wall shear stress inside the aneurysms. The current experimental model with the elastic wall has been carried out using part...

A 15-year-old boy presented to our hospital with headache after head trauma caused by a traffic accident. T2-weighted axial MR-images demonstrated the deep medullary veins of the cerebellum converging on the roof of the fourth ventricle. These veins drained into the subependymal vein, which then drained into the precentral cerebellar vein (Figure 1). MR-cisternography with 3D Fourier transformation constructive interference in steady state (CISS), which can depict the venous anatomy when it is s...
