OBJECTIVE In recent years, percutaneous laser disc decompression (PLDD) has become a routine surgical procedure because it can be performed under local anesthesia and is minimally invasive. However, there is a risk of nerve root and endplate injury owing to heat generated by laser irradiation during PLDD. We recently performed salvage surgery on a patient(More)
STUDY DESIGN This study was aimed at investigating changes in the dorsal horn of the lumbar cord induced by mechanical compression using an in vivo model. OBJECTIVE To determine the effect of axonal flow disturbance in the dorsal horns induced by nerve root compression. SUMMARY OF BACKGROUND DATA Few studies have looked at changes of synapses within the(More)
OBJECTIVE Stress is thought to be one of the triggers of relapses in patients with inflammatory bowel disease (IBD). We examined the rate of relapse in IBD patients before and after the Great East Japan Earthquake. DESIGN A retrospective cohort study. SETTINGS 13 hospitals in Japan. PARTICIPANTS 546 ulcerative colitis (UC) and 357 Crohn's disease (CD)(More)
STUDY DESIGN The aim of this study is to investigate changes in lumbar motor neurons induced by mechanical nerve root compression using an in vivo model. This study is to investigate the changes of lumbar motor neuron induced by mechanical nerve root compression using in vivo model. OBJECTIVES The effect of axonal flow disturbance induced by nerve root(More)
In this report, we describe a small schwannoma of the dural sleeve and mention that it is often difficult to differentiate this tumor from lumbar disc herniation, especially a sequestered hernia, or a discal cyst. Gadolinium-enhanced MR images were a useful preoperative examination modality for differentiating this lesion from other diseases.(More)
The authors describe the clinical course and treatment of a patient with cleidocranial dysplasia in whom spastic myelopathy developed due to atlantoaxial subluxation. This 27-year-old woman with cleidocranial dysplasia and a history of atlantoaxial subluxation presented with spastic myelopathy. Surgery was performed twice for cervical myelopathy and(More)
OBJECT The vascular terminations (vascular buds) in the bone-disc junction area are structurally very similar to cartilage. In all previous studies to date, however, the roles of cartilage canals and vascular buds were mainly discussed using histological and transparent sections but not electron microscopic sections. The purpose of this study was to clarify(More)
BACKGROUND AND STUDY AIMS Intramucosal vascular density differs between differentiated and undifferentiated type gastric carcinomas. This study aimed to evaluate the microvascular density characteristics of these two types of carcinoma using magnifying endoscopy with narrow-band imaging (ME-NBI). PATIENTS AND METHODS In total, 42 differentiated and 10(More)
We present an instructive case of habitual left patellar dislocation in which the patella had appeared odd due to lateral tilt relative to contralateral side, but had been radiologically confirmed to be on the trochlea at 1 year prior to the referral. An 11-year-old girl presented to our hospital 2 years after the left patella had dislocated with a 'giving(More)
