Recurrent Intracerebral Hemorrhage after Exercise in a Young Patient Presenting with Sporadic Cerebral Amyloid Angiopathy in a Young Patient.

Cerebral Amyloid Angiopathy (CAA) is one of the significant causes of lobar intracerebral hemorrhage (ICH) mainly among elderly people. Sporadic cases of CAA have been linked to genetic polymorphisms with an increased risk of disease, an earlier presentation, and an accelerated pathology [1]. Here, we present a patient with no significant risk factors who had a recurrent intracerebral hemorrhage secondary to CAA probably induced by exercise.

Pediatric Primary Diffuse Leptomeningeal Primitive Neuroectodermal Tumor: A Case Report and Literature Review.

Background: Primary diffuse leptomeningeal primitive neuroectodermal tumor (PDL PNET) is extremely rare, with only 19 cases reported in the literature to date. We present a case of a child with rapidly progressive PDL PNET and a literature review. A 10-year-old boy presented with mood lability, hallucinations, generalized pain, enuresis, and headaches.

A mathematical evaluation of hemodynamic parameters after carotid eversion and conventional patch angioplasty.

Carotid endarterectomy has a long history in stroke prevention, yet controversy remains concerning optimal techniques. Two methods frequently used are endarterectomy with patch angioplasty (CEAP) and eversion endarterectomy (CEE). The objective of this study was to compare hemodynamics-related stress and strain distributions between arteries repaired using CEAP and CEE.

Nonlinear mechanical behavior of the human common, external, and internal carotid arteries in vivo.

Background: The mechanical environment and properties of the carotid artery play an important role in the formation and progression of atherosclerosis in the carotid bifurcation. The purpose of this work was to measure and compare the range and variation of circumferential stress and tangent elastic moduli in the human common (CCA), external (ECA), and internal (ICA) carotid arteries over the cardiac cycle in vivo.

Methods: Measurements were performed in the surgically exposed proximal cervical CCA, distal ECA, and distal ICA of normotensive patients (n = 16) undergoing carotid endarterectomy.
