PURPOSE To explore a more effective treatment for newly diagnosed stage IV, relapsed, or refractory extranodal natural killer/T-cell lymphoma, nasal type (ENKL), we conducted a phase II study of the steroid (dexamethasone), methotrexate, ifosfamide, L-asparaginase, and etoposide (SMILE) regimen. PATIENTS AND METHODS Patients with newly diagnosed stage IV,(More)
OBJECTIVE To determine the extent of audiometric correlation with CT findings. METHODS Forty-four patients (82 ears) with surgically confirmed otosclerosis underwent preoperative CT examination. Based on the computed tomography (CT) findings, the ears were classified into five groups as follows: Group A, the group with no pathological CT findings; Group(More)
The route of the cochlear nerve can be imaged using computed tomography (CT) or magnetic resonance imaging (MRI). To gain information about the cochlear nerve, we conducted a trial measuring the width of the cochlear nerve canal (CNC) using CT. When we examined images of the route of the cochlear nerve on MRI, both in ears with congenital sensorineural(More)
Elective embolotherapy for recurrent hemoptysis was evaluated for its effectiveness. Forty embolotherapeutic procedures were performed in 30 patients. In the short term, complete hemostasis was achieved in 16 of 40 procedures (40%) and significant improvement in another 16 procedures (40%). Long-term complete hemostasis was achieved in 14 of 34 procedures(More)
Comparing bufuralol 1'-hydroxylase activity among liver microsomes prepared from individuals whose CYP2D6 genotypes had been determined, we found that the activity tended to decrease depending on the number of the CYP2D6*10 allele. Pre-incubation of liver microsomes from individuals homozygous for the CYP2D6*10 allele resulted in a decrease in the enzyme(More)
An unusual case of glioblastoma with adenoid structures arising in a 30-year-old Japanese woman with neurofibromatosis type-1 (NF1) is reported. The patient was admitted to University of Miyazaki Hospital, complaining of headache, nausea and vomiting. From the neuroradiological findings the patient was diagnosed as having glioblastoma, and the tumor was(More)
BACKGROUND Chronic pain is defined as intractable pain caused by abnormal pain transmission or impairment of the pain control system per se. Alteration of regional cerebral blood flow (rCBF) is known to occur under the presence of pain stimulation. Epidural spinal cord stimulation (SCS) is occasionally effective in relieving the symptom. OBJECTIVE The aim(More)
OBJECTIVE This study, was conducted to determine the clinical value of diffusion-weighted MR imaging (DWI) in detecting the presence of cholesteatoma. SUBJECT AND METHODS Fifty-six patients (21 female and 35 male patients; mean age, 43 years) who underwent middle ear surgery were referred to the radiology department for a preoperative DWI study. RESULTS(More)
UNLABELLED The current study is an investigation of alterations in regional cerebral blood flow (rCBF) distribution in patients with transient hypothyroidism after thyroidectomy. In addition, the effects of thyroxine treatment on rCBF changes were studied. METHODS Noninvasive rCBF measurements using 99mTc-HMPAO SPECT were performed on 24(More)
In this work, we examined structural changes of actin filaments interacting with myosin visualized by quick freeze deep-etch replica electron microscopy (EM) by using a new method of image processing/analysis based on mathematical morphology. In order to quantify the degree of structural changes, two characteristic patterns were extracted from the EM(More)
