The relationship between the features of MRI in brainstem and pathological findings was investigated in eight autopsy cases with progressive supranuclear palsy (PSP). Features of T1-weighted images at midbrain level were atrophy of tegmentum and tectum, and dilatation of aqueduct. Histologically, these findings were consistent with atrophy of periaqueductal(More)
OBJECT Previous studies of surgical complications associated with posterior lumbar interbody fusion (PLIF) are of limited value due to intrastudy variation in instrumentation and fusion techniques. The purpose of the present study was to examine rates of intraoperative and postoperative complications of PLIF using a large number of cases with uniform(More)
OBJECT The authors investigated the background, risk factors, and treatment strategies for Charcot spinal disease (CSD) after spinal cord injury (SCI). METHODS The authors retrospectively examined the clinical and radiological findings in 9 patients with a total of 10 Charcot spine lesions that occurred after SCI. The mean age of the 9 patients was 54(More)
OBJECT The management of isthmic spondylolisthesis remains controversial, especially with respect to reduction. There have been no reports regarding appropriate slip reduction. The purpose of this study was to investigate the following issues: (1) surgical outcomes of posterior lumbar interbody fusion (PLIF) with total facetectomy for low-dysplastic isthmic(More)
The purpose of this retrospective study was to demonstrate the surgical outcomes of anterior spinal fusion (ASF) and posterior subtraction osteotomy (PSO) for osteoporotic vertebral collapse (OVC). Forty patients who underwent surgery for OVC at the thoracolumbar junction with neurological deficits were included in this study. ASF was primarily chosen for(More)
Study Design Retrospective clinical study. Objective To investigate the age-related surgical outcomes of laminoplasty. Methods One hundred patients who underwent an en bloc laminoplasty for cervical spondylotic myelopathy from 2004 to 2008 and were followed for at least 1 year were included in this study. The clinical outcomes were assessed with the(More)
Adult T cell leukemia/lymphoma (ATL) is a highly aggressive malignancy of T cells caused by human T cell lymphotropic virus type 1 (HTLV-1). Recent clinical studies have suggested that allogeneic stem cell transplantation (HSCT) improves the clinical course of ATL by harnessing a graft-versus-ATL effect, and that donor-derived HTLV-1 Tax-specific CD8+(More)
OBJECTIVE Tranexamic acid (TXA), a synthetic antifibrinolytic drug, has been reported to reduce blood loss in orthopedic surgery, but there have been few reports of its use in spine surgery. Previous studies included limitations in terms of different TXA dose regimens, different levels and numbers of fused segments, and different surgical techniques.(More)
Study Design Case report. Objective To present two cases of neurogenic shock that occurred immediately following posterior lumbar interbody fusion (PLIF) and that appeared to have been caused by the vasovagal reflex after dural injury and incarceration of the cauda equina. Case Report We present two cases of neurogenic shock that occurred immediately(More)
A 74-year-old, right handed man, developed insidiously with levitation and clumsiness of the right upper limb. His right arm tended to levitate spontaneously, when he was examined. He could put the elevated arm down on command, while the arm resumed to antigravity posture when his attention was diverted. His right arm also exhibited unwilled elevation when(More)
