In this work, the brain lesions that cause spontaneously hyperintense T1 signal on MRI were studied under seven categories. The first category includes lesions with hemorrhagic components, such as infarct, encephalitis, intraparenchymal hematoma, cortical contusion, diffuse axonal injury, subarachnoid hemorrhage, subdural and epidural hematoma, intraventricular hemorrhage, vascular malformation...

We identified 1,369 consecutive patients who received glycoprotein IIb/IIIa inhibitors during 1,461 stenting procedures (2,382 lesions); of these, 240 (17.5%) were aged > or =75 years (253 procedures, 430 lesions). Very elderly patients (> or =75 years) had similar in-hospital outcomes but a higher hemorrhagic stroke rate than patients aged <75 years.

BACKGROUND AND PURPOSE The cause of intracranial bleeding in moyamoya disease patients is still unknown. To identify factors that contribute to bleeding, we assessed the angiographic findings of moyamoya disease patients. METHODS We examined angiograms obtained from 107 moyamoya patients; 70 manifested ischemic and 37 had hemorrhagic lesions. Patients with intracerebral aneurysms or both hemo...

argas reflexus is considered obligate blood feeder that may cause skin redness and local swelling. for histopathological evaluation of biting site, pigeons were used as natural host species in this study. adult ticks were collected from urmia, north-west of iran and kept in a desiccator before their use in the experiment. sixteen pigeons were infested experimentally and were divided into 4 grou...

traumatic basal ganglia hematoma is a rare condition defined as presence of hemorrhagic lesions in basal ganglia or adjacent structures suchas internal capsule, putamen and thalamus. bilateral basal ganglia hematoma are among the devastating and rare condition. we herein report a 28-year old man, a victim of car-car accident who was brought to our surgical emergency room by immediate loss of co...

Spinal cord injury (SCI) is typically complicated by progressive hemorrhagic necrosis, an autodestructive process of secondary injury characterized by progressive enlargement of a hemorrhagic contusion during the first several hours after trauma. We assessed the role of Abcc8, which encodes sulfonylurea receptor 1 (SUR1), in progressive hemorrhagic necrosis. After SCI, humans and rodents exhibi...

vious to the onset of lesions; therefore they scratched their skin. We observed that these patients presented more lesions and that they were more disseminated than in those patients without pruritus. What is more relevant, in patients 2, 3 and 4 some of the lesions had a linear, Koebner-like, arrangement (Figure 1B). Strikingly, patient 3 developed new lesions on the stitches at the site of bi...

BACKGROUND Copper is an essential element in various metabolisms. The investigation was carried out to evaluate acute gastroprotective effects of the Copper (II) complex against ethanol-induced superficial hemorrhagic mucosal lesions in rats. METHODOLOGY/PRINCIPAL FINDINGS Rats were divided into 7 groups. Groups 1 and 2 were orally administered with Tween 20 (10% v/v). Group 3 was orally admi...

A survey of inbred strains of mice was made to determine whether the phenomenon of dermal hemorrhagic necrosis, as described in rabbits by Shwartzman, could be elicited in mice by bacterial polysaccharide preparations of demonstrated activity in rabbits. The polysaccharide preparations used were obtained from cultures of S. marcescens, S. typhosa, Ps. aeruginosa, and H. pertussis. Ten of the st...
