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)
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)
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)
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)
PURPOSE To evaluate the clinical outcome of the extrapedicular approach of percutaneous vertebroplasty (PVP) for upper and mid-thoracic vertebral compression fractures in patients. MATERIAL AND METHODS Extrapedicular vertebroplasty was performed in painful compression fractures at T4-T8 levels. The assessment criteria were changes over time in visual(More)
Fabry disease is an X-linked lysosomal disease caused by deficiency of α-galactosidase, in which early diagnosis may be missed due to the wide variety of clinical symptoms presenting during disease progression. A 13 year-old boy visited our pain clinic complaining of pricking and burning pain in the toe tips of both feet. Continuous epidural infusion for(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)
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)
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)
