BACKGROUND AND OBJECTIVES Ultrasound-guided cervical periradicular steroid injection (US-CPSI) is an attractive alternate to conventional C-arm guided transforaminal epidural injection for treatment of cervical radicular pain. We compared the technical differences and clinical outcomes between these two techniques. METHODS Following ultrasound-guided(More)
An organophosphate pesticide terbufos (S-t-butylthiomethyl-O,O-diethyl phosphorodithioate; TBF) has been extensively used as an insecticide. A sexual dimorphism in TBF toxicity was not reported and remains unclear. The objective of the work was to investigate the influence of TBF on sexual dimorphism after oral administration of TBF to rats by using(More)
There are currently no initial guides for the diagnosis of somatic referred pain of lumbar zygapophyseal joint (LZJ) or sacroiliac joint (SIJ). We developed a classification system of LZJ and SIJ pain, the ''pain distribution pattern template (PDPT)'' depending on the pain distribution patterns from a pool of 200 patients whose spinal pain source was(More)
OBJECTIVE Pressure-controlled manometric discography is used by clinicians to evaluate discogenic pain. However, some would improve diagnostic accuracy. The goal of this study was to investigate potential confounding factors that might affect discographic results. Pressure differences depending on different speed of injection, lengths of connecting tubing(More)
Few studies have been conducted to explain the pain patterns resulting from osteoporotic vertebral compression fractures (OVCF). We analyzed pain patterns to elucidate the pain mechanism and to provide initial guide for the management of OVCFs. Sixty-four patients underwent percutaneous vertebroplasty (N=55) or kyphoplasty (N=9). Three pain patterns were(More)
OBJECTIVE Researchers and clinicians have been unable to fully elucidate the natural course of and proper treatment for unruptured intracranial aneurysms (UIAs) smaller than or equal to 5 mm, particularly with regard to whether close observation or surgery is more appropriate. In this retrospective study, we evaluated the safety and efficacy of endovascular(More)
Distal middle cerebral artery aneurysm is rare and can develop from trauma, infection, atherosclerosis, or surgery. Nasogastric (NG) tube insertion is a common and safe procedure for stroke patients with dysphagia. In this case, the patient showed right internal border-zone infarction without major arterial occlusion. Magnetic resonance angiography of the(More)
OBJECTIVE Endovascular treatment is one of the most important treatments along with open craniotomy for cerebrovascular surgery. The successful treatment of endovascular disease relies on appropriate instruments and the surgeon's skill. Endovascular treatment needs to provide safe and stable access to the catheter cavity. Additionally, it is important to(More)
Encapsulated acute subdural hematoma (ASDH) has been uncommonly reported. To our knowledge, a few cases of lentiform ASDH have been reported. The mechanism of encapsulated ASDH has been studied but not completely clarified. Encapsulated lentiform ASDH on a computed tomography (CT) scan mimics acute epidural hematoma (AEDH). Misinterpretation of(More)
