OBJECTIVES:The requirements of biliary stents used in the palliation of malignant biliary obstruction are a long duration of patency and minimal adverse effects. Covered self-expandable metal stents (SEMSs) have been shown to prevent tumor ingrowth, which is the most frequent complication of uncovered SEMSs. However, because they are prone to migration, the(More)
We examined the distribution and origin of the nerve fibers innervating the dura mater of the rat that show immunoreactivity for the TRPV1 receptor (TRPV1-IR). Nearly 70% of the nerve fibers showing TRPV1-IR in the dura mater also exhibited CGRP-IR. Using a combination of immunohistochemistry and a retrograde tracer technique, we detected tracer(More)
We report a case of pretibial cyst formation, which is a rare complication, after anterior cruciate ligament (ACL) reconstruction. The patient had undergone ACL reconstruction at age 18 and complained of pain and swelling localized on the anteromedial aspect of the ipsilateral proximal tibia 2 years postoperatively. Magnetic resonance imaging showed a(More)
BACKGROUND Osteochondral autografts have recently become popular to treat articular cartilage defects, and they are used for unstable osteochondritis dissecans lesions as a means of biological fixation. PURPOSE To evaluate the clinical results of osteochondral autograft transfer for osteochondritis dissecans of the elbow. STUDY DESIGN Case series; Level(More)
REM sleep behavior disorder (RBD) is known to be observed more frequently in patients with an α-synucleinopathy such as Parkinson’s disease (PD) than in the general population. The precise prevalence of RBD in Japanese PD patients is not known. Therefore, we investigated the prevalence and the clinical characteristics of patients with RBD in a large(More)
OBJECTIVE The aim of this work was to investigate the prevalence of camptocormia and the clinical characteristics of patients with camptocormia in a large population of PD patients. BACKGROUND Although camptocormia has been recognized as a prominent phenomenon in PD, the previous epidemiological reports were limited, especially in terms of sample size. (More)
The purpose of this study was to assess double-bundle anterior cruciate ligament (ACL) reconstruction, which reproduces the anteromedial bundle and posterolateral bundle, using a navigation system. In 32 patients, anteroposterior (AP) displacement and rotation of the tibia were measured before reconstruction and after posterolateral bundle fixation,(More)
The human lectin-like oxidized low-density lipoprotein receptor 1 (OLR1/LOX-1) is the major endothelial scavenger receptor against oxidized low-density lipoprotein (Ox-LDL), which has been implicated in the pathogenesis of atherosclerosis. We investigated the G501C mutation in the OLR1 gene in 235 Japanese patients with ischemic cerebrovascular disease(More)
