Brain dysfunction and blood flow velocity changes in the middle cerebral artery (MCAFV) were studied in 59 patients with ruptured cerebral aneurysms presenting subarachnoid hemorrhage. Brain function and blood flow velocity were evaluated by multimodality evoked potentials (MEPs) consisting of ABR, SEP and VEP as reported, and transcranial Doppler (TCD)(More)
The importance of coexisting diffuse axonal injury (DAI) and outcome were studied in 107 patients with diffuse and focal brain injury. Comprehensive neuropathological study was undertaken in 26 fatal patients. There was a clear rank order of the mortality rate in the lesion type. The rank order of good recovery and moderate disability was also similar to(More)
Intracranial haemodynamics were studied in 20 patients with diffuse and focal brain injury and experimental animals with acute intracranial hypertension by the use of TCD ultrasound. The mean flow velocity in the middle cerebral artery (MCA) commonly decreased on the side of the haematoma depending on intracranial pressure (ICP) elevation and cerebral(More)
An 11-year-old boy with congenital radial head dislocation experienced painful snapping of his left elbow upon movement. He had no previous history of trauma. A plain radiograph of his left elbow showed anterior dislocation of the radial head and flexion deformity of the hypoplastic radial neck. Arthroscopy showed that the snapping of the elbow occurred(More)
De Quervain disease is caused by a stenosing tenosynovitis in the first dorsal compartment, and the main aetiology is extensor pollicis brevis (EPB) tenosynovitis. We encountered three cases in which EPB tenosynovitis was absent and abductor pollicis longus (APL) tenosynovitis was confirmed during operation. In the treatment of de Quervain disease, APL(More)
BACKGROUND Uterine sarcoma is a rare tumor that is often difficult to classify based on morphological and immunohistochemical analysis alone. Limited access to molecular biological analysis in routine practice would hinder making a definitive diagnosis. CASE PRESENTATION In this report, we describe a case of a mesenchymal tumor arising from the uterine(More)
Aseptic bone flap resorption, a rare complication after cranioplasty following decompressive craniectomy, is more likely to develop in children. We experienced two cases of aseptic bone flap resorption and identified potential pathophysiological mechanisms through histological findings. In the first case, an 11-year-old girl underwent decompressive(More)
BACKGROUND Pseudomyogenic hemangioendothelioma (PHE) is an unusual vascular tumor of intermediate malignancy that rarely metastasizes and tends to arise in the lower limbs of young adults and children. Histologically, PHE shows fascicular proliferation of eosinophilic spindle cells and/or epithelioid cells showing "pseudomyogenic" morphology.(More)
We encountered 8 cases of acute subdural hematoma caused by mild head trauma in the aged. In this report, these cases were analyzed, taking into consideration clinical symptoms, CT scan, operative findings and outcome. The age ranged from 70 to 92 years (mean age of 79.7 years). 4 patients were male and 4 female. Head trauma was caused by falls in 4(More)
Intracranial haemodynamics were studied in 36 patients with severe head injury and experimental animals with acute intracranial hypertension by the use of TCD ultrasound. The mean flow velocity (FV) in the basal cerebral arteries commonly decreased on the side of the haematoma depending on intracranial pressure (ICP) elevation and cerebral perfusion(More)
