BACKGROUND This study was performed to verify reports of the decreased accuracy of endorectal ultrasonography (EUS) in preoperative staging of rectal cancer, and to compare the efficacy of 3-dimensional (3D) EUS with that of 2-dimensional (2D) EUS and computed tomography (CT). METHODS Eighty-six consecutive rectal cancer patients undergoing curative(More)
OBJECTIVE Although the diagnosis of metachronous colorectal cancer have increased, due primarily to improvements in diagnostic modalities, the potential risk factors for these tumours are not well known. We compared the characteristics of patients with metachronous and sporadic primary colorectal cancer to determine risk factors for its occurrence. (More)
The regulators of G protein signaling (RGS) are a family of proteins with conserved RGS domains and play essential roles in regulating G protein-mediated signal transduction and physiological events. GAIP/RGS19 (G alpha interacting protein, also classified as RGS19), a member of the RGS family, has been shown to negatively regulate the signaling of many G(More)
AIMS Local anaesthetics, which act as neurolytics and Na(+) channel blockers, have been used for disrupting the neural firings in certain neuropathic pain conditions. This study was undertaken to investigate the clinical outcome of trigeminal nerve block with 10% lidocaine in the management of trigeminal neuralgia (TN). METHODS Thirty-five patients with(More)
BACKGROUND Raynaud's phenomenon (RP) associated with connective tissue disease (secondary RP) may be difficult to manage with conservative therapy. A combination of sympathetically mediated vasospasm and vaso-occlusion has been implicated as the etiology of digital ischemic phenomenon. Thoracic sympathetic outflow blocking has been performed with various(More)
BACKGROUND Cervical interlaminar epidural injection (CIEI) is widely used in the management of acute or chronic neck and upper extremity pain. There is no consensus regarding the optimal volume of solution to be used for CIEI. STUDY DESIGN Randomized, double blind controlled trial. OBJECTIVE The purpose of this study was to evaluate how many spinal(More)
Hyperhidrosis is a disorder of perspiration in excess of the body's physiologic need and significantly impacts one's occupational, physical, emotional, and social life. The purpose of our study was to investigate the characteristics of primary hyperhidrosis in 255 patients at Ajou University Hospital Hyperhidrosis Center from March 2006, to February 2008.(More)
Regulators of G protein signaling (RGS) proteins are GTPase-activating proteins which act as modulators of G-protein-coupled receptors. RGS9 has two alternative splicing variants. RGS9-1 is expressed in the retina. RGS9-2 is expressed in the brain, especially abundant in the striatum. It is believed to be an essential regulatory component of dopamine and(More)
BACKGROUND Transforaminal epidural injection (TEI) is commonly used in the treatment of radicular pain. However, there have been many published cases of serious complications after a TEI, occurring most often in cervical levels. One of the presumptive reasons for this complication is inadvertent intravascular injection. We sought to identify the incidence(More)
Ninety-eight patients received 160 mandibular nerve (V3) blocks with alcohol for the treatment of trigeminal neuralgia in this prospective study. According to the Kaplan-Meier analysis, the probabilities of remaining pain free for 1, 2, 3, and 7 years after the procedures were 90.4%, 69%, 53.5%, and 33%, respectively. There was no significant difference in(More)
