Exposure of blood to tissue factor (TF) activates the extrinsic (TF:FVIIa) and intrinsic (FVIIIa:FIXa) pathways of coagulation. In this study, we found that mice expressing low levels of human TF ( approximately 1% of wild-type levels) in an mTF(-/-) background had significantly shorter lifespans than wild-type mice, in part, because of spontaneous fatal hemorrhages. All low-TF mice exhibited a...
Twenty-nine patients with true arteriovenous malformations as diagnosed by MR imaging or angiography were examined by MR to detect the presence of hemosiderin deposition, a marker for remote hemorrhage. The resulting information was compared with the clinical record to determine the frequency with which MR demonstrated prior hemorrhagic episodes where no clinical evidence for such episodes exis...
In normal adult males, about 25%o of the body iron content is in storage depots (1). This iron exists in two forms: as a diffuse soluble fraction called ferritin, in which the molecules are dispersed, and as insoluble aggregates of hemosiderin, which can be visualized by conventional microscopy (2). Although the liver is regarded as the chief storage organ, chemical analyses suggest that it nor...
INTRODUCTION Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative disorder of the synovial membrane that typically presents in adults and affects a single joint. Multifocal PVNS is very rare, particularly in childhood. We reported a rare case of multifocal PVNS affecting over 20 joints in a child. CLINICAL PROCEDURE A 7-year-old female patient had a 6-month history of multi...
PURPOSE To describe and emphasize importance of recognizing superficial siderosis (SS) of the central nervous system (CNS) when assessing cerebellar ataxia syndrome CASE REPORT Superficial siderosis (SS) of the central nervous system (CNS) is a rare disorder that results from chronic hemosiderin deposition in the subpial layers of the brain and the spinal cord. Although recurrent bleeding in ...
Iron is one of the most abundant elements, essential for the completion of numerous important biological functions, including electron transfer reactions, gene regulation, binding and transport of oxygen, regulation of cell growth and differentiation. In the human body it is mainly found in the oxygen transport and storage proteins haemoglobin (Hb) (60 70%) and myoglobin (10%), in various iron-...
BACKGROUND AND PURPOSE Patients with spontaneous intracerebral hemorrhage (ICH) frequently have small areas of signal loss on gradient-echo T2*-weighted MR images, which have been suggested to represent remnants of previous microbleeds. Our aim was to provide histopathologic support for this assumption and to clarify whether the presence and location of microbleeds were associated with microang...
