STUDY DESIGN A prospective, randomized, controlled study. PURPOSE The objective of this study was to evaluate the effectiveness of two techniques of skin preparation with povidone-iodine. OVERVIEW OF LITERATURE Preoperative skin preparation is important for preventing surgical site infection by reducing the bacteria in the surgical area. Povidone-iodine(More)
A recurrent laryngeal nerve injury is known as a complication referring to an anterior cervical spine surgery. However, hypoglossal nerve injury is not well known yet. Herein we report a rare case of a 39-years-old male with a hypoglossal nerve injury after C3/4 osteophyte resection with Smith-Robinson approach. In this case there appeared difficulties of(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. We are extremely grateful for your interest in our manuscript. The report by Saunders et al. was very helpful. As you indicated, there are reports about hypoglossal nerve palsy (HNP) after soft tissue surgery of the(More)
STUDY DESIGN Retrospective case series. PURPOSE To investigate the relationship between tumor location and clinical characteristics. OVERVIEW OF LITERATURE Hemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as(More)
Authors have developed a mandibular retraction system in a rat that was constructed by arms having a metal mesh, an incisor metal cap, a pair of closed coil springs and a soft plastic collar. The merit of this system is that the anchor is very stable because it is made on the parietal bones, and the direction and load of the traction are invariable(More)
Meningioma is typically considered to be a benign tumor. Malignant transformation and metastasis of meningiomas are rare. Moreover, most meningiomas are intracranial, and there are few reports on intraspinal meningiomas. This report aimed to describe the clinical features and pathological findings of a case of malignant transformation and distant metastasis(More)
BACKGROUND Glial and fibrotic scars inhibit neural regeneration after spinal cord injury (SCI). N-[3,4-dimethoxycinnamoyl]-anthranilic acid (tranilast) inhibits transforming growth factor β, alleviates allergic reactions, and decreases hypertrophic skin scars. We evaluated its ability to improve motor function and inhibit the spread of tissue damage in rats(More)
Peripheral nerve injury (PNI) triggers cellular and molecular changes in the spinal cord. However, little is known about how the polyunsaturated fatty acid-containing phosphatidylcholines (PUFA-PCs) are regulated in the spinal cord after PNI and the association of PUFA-PCs with the non-neuronal cells within in the central nervous system (CNS). In this(More)
Objective When we perform surgical correction for spinal deformity with degenerative changes, nerve root impingement, traction , or nerve root injury could be occurred. Electromyo-graphic (EMG) monitoring provides a real-time measure of impending spinal nerve root injury during instrumented posterior lumbar fusion. However, the utility of intraopera-tive(More)
Sagittal alignment in Japanese elderly people-how much can we tolerate as normal sagittal vertical axis? Objectives Spinal sagittal alignment has been reported that it is highly associated with health related QOL in adult spinal deformity patients. Optimal sagittal alignment is critical for the efficient function of the musculoskeletal system. In Japan as(More)
