Hemorrhagic stroke is a disease with high incidence and mortality rates. In addition to the mass lesions that result from hemorrhagic stroke, substances such as the blood-derived products (BDP) (hemoglobin (Hb), heme and iron) induce a potent inflammatory response and exert direct toxic effects on neurons, astrocytes, and microglia. In the present review, we discuss the mechanisms of brain inju...

The Rous chicken sarcoma and its causative virus have been intensively studied since Peyton Rous first reported the transmissibility of the tumor by a filtrable agent (10). I t is known that Rous sarcoma virus (RSV) can propagate in tissues other than tumor. Groupe and Rauscher (4) demonstrated progressive propagation in chicken brain after intracerebral inoculation. Groupe et al. (5) found vir...

abstract objective ethylmalonic encephalopathy (ee) is a severe mitochondrial disease of early infancy clinically characterized by a combination of developmental delay, progressive pyramidal signs and vascular lesions including petechial purpura, orthostatic acrocyanosis and chronic hemorrhagic diarrhoea. biochemical hallmarks of the disease are persistently high levels of lactate, and c4–c5-ac...

BACKGROUND AND PURPOSE Multifocal microhemorrhages have been reported to be commonly found in the brain of patients with systemic hypertension and spontaneous brain hemorrhage. The factors associated with these lesions detected on T2*-weighted gradient-echo images were examined to determine whether these lesions serve to indicate different types of microangiopathy and to predict a patient's ris...

BACKGROUND AND PURPOSE The effect of low molecular weight heparin (LMWH) in the management of cerebral venous thrombosis (CVT) remains unclear. The present study was performed to determine the safety and feasibility of subcutaneous LMWH, with particular attention to hemorrhagic conversions. METHODS LMWH (nadroparin, 7,500 ICU, every 12 hours) was administered subcutaneously for 14 days to 12 ...

Acute hemorrhagic edema of infancy (AHEI) is a rare skin disorder which was first described by Snow in 1913. Clinical manifestations are usually limited to cutaneous lesions and is most commonly observed in infants under the age of 1 year. Usually, there is a history of recent upper respiratory tract infection and antibiotic administration. Clinical presentation of this disease includes petechi...

Pyogenic granuloma is a hemorrhagic nodule that happens utmost often on the gingiva (although it can occur any surface) and has robust penchant to persist after simple excision if connected irritant not removed. Clinically these lesions usually present as single or sessile papule with smooth lobulated surface. These may be seen in size from few millimeters several centimeters. Here, we report c...

Retrosternal extension of goiter is one the most common types masses in superior mediastinum. These goiters classically present with compressive symptoms such as dyspnoea, dysphonia, dysphagia, or sleep apnea. Surgical treatment a total thyroidectomy and complete removal intrathoracic portion thyroid gold standard treatment. cervico-mediastinal lesions at times may not be continuous, sternotomy...

Furthermore high vascular lesions may present high perfusion as well as brain cancer. The symmetrical calcifications and the diffuse enhancing nodular lesions are other important findings that suggest a diffuse cerebral condition. Actually the nodular enhancing lesions constitute pre-cystic lesions as same cases show in the literature. Actually the leucodistrophy described in this entity is rat...
