STUDY DESIGN A retrospective, consecutive case series. OBJECTIVE To determine the risk factors that have a statistically significant association with the need of tracheostomy in patients with cervical spinal cord injury (CSCI) at the acute stage. SUMMARY OF BACKGROUND DATA Respiratory complications remain a major cause of further morbidity and mortality(More)
Few studies have reported the characteristics of Modic changes (MCs) in the cervical spine in contrast to the lumbar spine. The purpose of this study was to identify the prevalence of MCs in the cervical spine and to elucidate the relationship of MCs with spinal canal stenosis and angular motion. 437 consecutive, symptomatic patients with neck pain with or(More)
OBJECTIVE The present study was undertaken to evaluate clinical application of serum cystatin C as a new marker of glomerular filtration rate (GFR) in patients with various renal diseases. PATIENTS AND METHODS A total of 140 patients were enrolled in the study. We measured the serum cystatin C levels and compared them with creatinine clearance (Ccr) and(More)
OBJECTIVES To test, for the first time, the predictive capability of the total stone volume (TSV) and the attenuation value histogram. Recently, the mean attenuation value (MAV) of urinary stones has been recognized as a predictor of fragility by extracorporeal shock wave lithotripsy. However, properties other than MAV, including the TSV and the(More)
BACKGROUND To assess the feasibility of laparoscope-guided minilaparotomy (endoscopic minilaparotomy) for renal cell carcinoma in patients on chronic dialysis. METHODS Endoscopic retroperitoneal minilaparotomy using a 30 degrees telescope was carried out through single skin incision (5-8 cm) in eight patients with renal cell carcinoma who were on chronic(More)
The 14C-deoxy-d-glucose technique was used to examine glucose utilization, as a measure of neuronal activity, in 100 cerebral nuclei by means of radiodensitometry of autoradiographs of serial brain sections. Three groups of rats were studied, namely young spontaneously hypertensive rats (SHR), adult SHR and normal Wistar-Kyoto rats whose blood pressure was(More)
We compared the prevalence of concurrent diseases (diabetes mellitus, hypertension, ischemic heart diseases and apoplexy) in patients with renal cell carcinoma, bladder carcinoma and prostatic carcinoma diagnosed in our department with that in all patients in our department analyzed using Mantel-Haenszel regression. In hypertension, there was a(More)
We report three cases with severe anastomotic strictures, which recurred several times after radical prostatectomy despite repeated treatments of urethral dilation, internal urethrotomy and/or transurethral resection. All three cases were finally treated with holmium laser successfully without any intraoperative or postoperative complications after repeated(More)
Although the association between dermatomyositis and cancer is well recognized, there have been a limited number of reports of dermatomyositis associated with testicular cancer. We report the case of a 31-year-old man who was diagnosed with dermatomyositis. Because the patient's serum levels of alpha-fetoprotein and human chorionic gonadotropin beta subunit(More)
