STUDY DESIGN The authors studied the origin of nerves supplying the posterior portion of lumbar intervertebral discs in rats by resection of the sympathetic trunks. OBJECTIVE To understand discogenic low back pain from the innervation of the lumbar intervertebral discs. SUMMARY OF BACKGROUND DATA The afferent pathways of discogenic low back pain have(More)
STUDY DESIGN The level of dorsal root ganglia that receives sensory afferent nerves from the anterior portion of the lower lumbar intervertebral disc was investigated in rats using a retrograde transport method. OBJECTIVES Sometimes patients with lower lumbar disc lesions complain of inguinal pain that does not correspond to the dermatome of the injured(More)
STUDY DESIGN The levels of dorsal root ganglia and paravertebral sympathetic ganglia innervating the lumbar facet joint were investigated in rats using the retrograde transport method. The pathways and functions of the nerve fibers supplying the lumbar facet joint were determined immunohistochemically. OBJECTIVES To study lumbar facet pain in relation to(More)
This study was designed to investigate neural mechanisms of referred pain in lumbar intervertebral disc lesions. Patients with a degenerative disc in lower lumbar segments occasionally complain of groin pain, which cannot be explained anatomically as having a radicular origin. In rats pretreated with intravenous application of Evans blue dye, the dye(More)
BACKGROUND Sleep-disordered breathing (SDB) has been recognized as an important risk factor for cardiovascular diseases; however, the impact of SDB on long-term outcomes in patients with acute coronary syndrome has not been fully evaluated. METHODS AND RESULTS We performed overnight cardiorespiratory monitoring of 241 patients with acute coronary syndrome(More)
BACKGROUND Stent fracture (SF) after drug-eluting stent implantation has become an important concern. The aim of this study was to assess the incidence, predictors, and clinical impact of SF after biolimus-eluting stent. METHODS AND RESULTS A total of 1026 patients with 1407 lesions undergoing the Nobori biolimus-eluting stent implantation and follow-up(More)
