The purpose of this study was to evaluate the linear and angular parameters vertebral body (VB) required for cervical pedicle screw (CPS) insertion by using multiplanar computerized tomography (CT) reconstructions.Three hundred fifteen vertebrae from C-3 C-7 in 63 patients were studied. Pedicle dimensions such as transverse angle (PTA), sagittal (PSA), outer width (POW) measured on axial CT reconstructions, including lateral mass thickness (LMT), anteroposterior (AP) mediolateral distances...
Abstract Background Bone mineral density (BMD) measurements are widely used to assess fracture risk. However, the finding that some patients had high BMD together with low contribution of drugs osteoporosis suggests bone strength factors other than contribute quality. We evaluated amount advanced glycation end products (AGEs) by non-invasive assays serum and urine as well skin autofluorescence measure levels a representative AGE, pentosidine, investigate whether pentosidine can serve an...
Eldecalcitol (ELD), an active form of vitamin D analog approved for the treatment osteoporosis in Japan, increases lumbar spine bone mineral density (BMD), suppresses turnover markers, and reduces fracture risk patients with osteoporosis. We have previously reported that ELD 6 months improved mechanical properties ovariectomized (OVX) cynomolgus monkeys. increased BMD, suppressed reduced histomorphometric parameters both formation resorption vertebral trabecular bone. In this study, we...
More than 290 cases of cerebral arteriovenous malformation have been treated at our hospital by Gamma Knife radiosurgery since May 1991, which 99 were followed with angiography for 1 year or more. The results from adult and pediatric age groups compared. There 70 adults 23 children. Previous hemorrhage had occurred in 73.7% the 91.3% mean volume nidus was similar both groups: 4.2 cm3 4.8 In approximately 70% fell into Spetzler Martin grade III. margin dose 20.0 Gy 20.5 Complete occlusion 45%...
Bazedoxifene (BZA) is used for the treatment of post-menopausal osteoporosis. To elucidate changes in collagen, mineralization, and structural properties their relationship to bone strength after with BZA ovariectomized (OVX) monkeys, levels collagen enzymatic immature, mature, non-enzymatic cross-links were simultaneously examined, as well trabecular architecture mineralization vertebrae. Adult female cynomolgus monkeys divided into 4 groups (n = 18 each) follows: Sham group, OVX given...
A retrospective multicenter study was performed to evaluate the effectiveness of Gamma Knife radiosurgery (GKRS) in treatment drug resistant epilepsy associated with cavernous hemangiomas (CH). The mean duration before GKRS 7.5 ¿ 9.3 years. frequency seizures 6.9 14/month. marginal dose 19.2 4.4 Gy (range 11.3 36 Gy). follow up 23.7 13 months. At most recent follow-up examination, 26 (53%) patients were seizure-free (Engel s class I) including 24 IA (49%) and two (4%) occasional auras (class...
A bifacial solar cell structure is applied to multicrystalline substrates obtained from the OTC cast material. The double sided cathode configuration made it possible collect photogenerated minority carriers nearest side of cell, which allows carrier not necessarily travel across substrate having short diffusion lengths. rear acts as a current booster for front light entering side, and vice versa. Because this two fold enhancement, outputs equivalent nearly 20% efficiency are obtainable 15%...
Lumbosacral dislocations are rare disorders; since they were first reported by Watson-Jones [1], only 100 cases have appeared in the literature [2]. A traumatic bilateral lumbosacral dislocation is even rarer, with a mere 10 [3]. Because of its low incidence and atypical location, lesion may often go unnoticed on initial clinical assessment [4]. Surgical treatment modalities not defined, but open reduction internal fixation necessary because three-column involvement [5]. In this paper, we...
Following identification of peak height velocity (PHV) by a recent study as possible prognostic factor for curve progression in patients with idiopathic scoliosis (IS), the aim this was to investigate PHV curves Japanese female IS. The subjects were 20 skeletally immature IS who followed until maturity. mean age and pubertal status at initial visit 9.8 years 24 months before menarche, respectively, follow-up period 5.2 years. Height measurements recorded each visit, HV calculated change (cm)...
A 39-year old woman with antiphospholipid antibody positive systemic lupus erythematosus (SLE) was admitted to our department because of high fever, liver dysfunction and level C-reactive protein. At hospitalization, there no anemia or jaundice. tumor palpable in the epigastric region, tenderness this but muscular defense. There were findings which indicated disease activity SLE. The result abdominal ultrasonography showed that a giant tumor, occupied majority left lobule liver, nonuniform...
