OBJECTIVE To determine the prognostic factors of the functional outcome of patients surgically treated for acute epidural hematomas. METHODS Two hundred patients who consecutively underwent neurosurgery for acute epidural hematomas over the past 9-year period were studied. Clinical characteristics, radiologic findings, and the time intervals with regard(More)
OBJECTIVE This study was conducted to evaluate the kinematic response of late fusion results for cervical spine discectomies with and without bone grafting. MATERIALS AND METHODS Fifteen Barbados Black Belly sheep underwent sham operations (Group A, n = 5), C2-C3 discectomies only (Group B, n = 5), and C2-C3 discectomies with autologous iliac bone(More)
OBJECT The authors sought to ascertain the nature of the hemodynamic and metabolic derangement underlying acute pathophysiological events that occur after intracerebral hemorrhage (ICH). METHODS Cerebral perfusion pressure (CPP), flow velocity (FV) of the middle cerebral artery, and the arteriovenous contents of oxygen and lactate were investigated in 24(More)
A 28-year-old man with a 5-year history of gouty arthritis suffered from an acute episode of lower back pain. He visited a rehabilitative clinic and received physical therapy following his examination. Weakness and numbness of both lower legs developed rapidly after physical therapy. He was sent to our hospital with complete paralysis of both lower limbs(More)
The aim of this study was to generate a transgenic mouse that ubiquitously expressed enhanced green fluorescent protein (EGFP) under the control of the murine phosphoglycerate kinase 1 promoter by allotransplantation of transgenic mouse ovaries. The EGFP transgenic mice expressed green fluorescence in many organs, and the fluorescence was detected as early(More)
Non-industrial robot applications are getting more popular than ever. Moving capability is one of the most important features of non-industrial robots. In general, the movements of non-industrial robots are categorized as wheeled and legged mechanical platforms. The wheeled platform performs stable and fast movement characteristics; however, it can not move(More)
To determine the influence of anemic hypoxia on cerebral hemodynamics and brain metabolism during pathological conditions of the brain, moderate-sized intracerebral hemorrhage (ICH) was created in canines with and without preoperatively inducing chronic anemia. The changes in cerebral perfusion pressure (CPP) and cerebral blood flow velocities (CBFv) were(More)
A 17-year-old male patient was brought to our clinic because of sudden onset of headache, vomiting, followed by transient loss of consciousness during a strenuous exercise. Neurologic examinations revealed that the patient had severe sensorimotor and brain stem dysfunction. Examinations of cranial CT and MR imaging showed a huge heterogeneously enhanced(More)
The present study was undertaken to investigate the influence of imposed anemic hypoxia on cerebral hemodynamics and metabolism in a condition of massive ICH. Two groups of eight dogs, with a target hemoglobin concentration of 12 g/dl in nonanemic and 6 g/dl in anemic group, were included. Before the onset of the insult, anemic group had a significant(More)
