BACKGROUND Lumbar spinal stenosis (LSS) is often a position-dependent condition that is aggravated in extension and relieved in flexion. METHODS Ten consecutive elderly patients with LSS were assessed postoperatively by magnetic resonance imaging and the Swiss Spinal Stenosis Questionnaire. Cross-sectional areas of the dural sac and intervertebral(More)
There is increasing evidence that bone marrow stromal cells (BMSC) have the potential to migrate into the injured neural tissue and to differentiate into the CNS cells, indicating the possibility of autograft transplantation therapy. The present study was aimed to clarify whether the mouse BMSC can migrate into the lesion and differentiate into the CNS(More)
The generation of induced neural stem cells (iNSCs) from somatic cells using defined factors provides new avenues for basic research and cell therapies for various neurological diseases, such as Parkinson's disease, Huntington's disease, and spinal cord injuries. However, the transcription factors used for direct reprogramming have the potential to cause(More)
OBJECTIVE AND IMPORTANCE Approximately 20 to 50% of patients with syringomyelia associated with Chiari malformations exhibit cranial nerve or cerebellar symptoms. However, hiccups represent a rare clinical manifestation of this disorder. We report a case of intractable hiccups resulting from syringobulbia associated with a Chiari I malformation, which was(More)
OBJECT Spinal cord edema is a rare radiological finding in chronic degenerative disorders of the spine. Between 1997 and 2001, the authors treated six patients with cervical spondylotic myelopathy in whom postoperative spinal cord edema was demonstrated. The authors describe the radiological and clinical features of this unusual condition. METHODS The six(More)
A 36-year-old female was treated for a perimedullary arteriovenous fistula (AVF) using intraoperative color Doppler sonography monitoring. Color Doppler sonography before interruption of the fistulous point clearly demonstrated an abnormal hyperechoic lesion. After interruption of the shunting point, the lesion had disappeared. Intraoperative angiography(More)
Brain inflammation causes cell damage and death in diseases such as Alzheimer’s and Parkinson’s. In this study, we investigated whether early induced neural stem cells (iNSCs) could protect against cell death after treatment with THP1-derived macrophages. We developed an inflammatory model system with THP1-derived macrophages and cortical neuronal cells and(More)
Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord impairment worldwide and is a risk factor for traumatic central cord syndrome. Despite advances in surgery, there are no effective neuroprotective treatments for CSM, which reflects a limited understanding of its pathophysiology. In order to develop therapeutic strategies, we have(More)
BACKGROUND Neuronal cells are vulnerable to many stresses that can cause apoptosis. Reprogramming of fibroblasts into induced neural stem cells (iNSCs) is a potentially unlimited source of neurons. Discovering agents that can provide neuronal protection against these apoptotic stimuli is important for developing therapeutic strategies for various brain(More)
Pierre-Robin syndrome (PRS) is a rare congenital malformation that shows severe micrognathia and cleft soft palate. A 15-year-old boy who was admitted with occipital headache and gait disturbance was diagnosed with PRS. Radiological evaluation revealed severe herniation of the cerebellar tonsil and multiple craniovertebral osseous anomalies. We carried out(More)
