- Study Design. Prospective cohort study. Objective. To compare the novel treatment procedure with nonoperative treatment for low back pain (LBP) in elderly patients with degenerative lumbar scoliosis (DLS). Summary of Background Data. Treatment of LBP associated with elderly DLS is controversial. We developed a novel treatment procedure, termed percutaneous intervertebral-vacuum polymethylmethacrylate injection (PIPI). Methods. We included patients with de novo DLS aged >= 65 years who had LBP with a visual analogue scale (VAS) score of >50 for >= 6 months with intervertebral vacuum and vertebral bone marrow edema (BME) defined on fat-saturated T2-weighted or gadolinium-enhanced T1-weighted magnetic resonance imaging. The primary outcomes were evaluated using the VAS score and modified Oswestry Disability Index (ODI). As an objective measurement, we scored BME on magnetic resonance imaging. Results. Between August 2004 and July 2011, 109 patients underwent PIPI and 53 received nonoperative treatment. At 1 month, mean improvements in VAS scores were -55.3 (95% CI, -60.5 to -50.1) and -1.9 (CI, -7.7 to 3.8) and mean improvements in ODI were -22.7 (CI, -27.3 to -18.2) and -0.6 (CI, -6.6 to 5.4) for the PIPI and nonoperative groups, respectively. At 2 years, mean improvements in VAS scores were -52.2 (CI, -59.9 to -44.4) and -4.0 (CI, -10.9 to 3.0) and mean improvements in ODI were -20.7 (CI, -27.3 to -14.5) and -1.0 (CI, -7.7 to 5.7) for the PIPI and nonoperative groups, respectively. BME substantially decreased in the PIPI group compared with the nonoperative group (P < 0.001) and correlated with VAS score and ODI improvements (VAS score: r = 0.502, P < 0.001; ODI: r = 0.372, P< 0.001). Conclusion. PIPI improved treatment for LBP, with a sustained clinical benefit for at least 2 years.

- Background: With aging of the population, the numbers of osteoporotic vertebral fractures with intravertebral cleft have been increasing. However, the details of clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft are poorly understood. The purpose of this study was to evaluate the relationship between clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft and radiographic findings. Methods: Two hundred seventeen patients with single-level osteoporotic vertebral fractures with intravertebral cleft were examined. Clinical symptoms were evaluated using Numerical Rating Scale for back pain and the Oswestry Disability Index for physical disability. The presence of delayed neurologic deficit was also detected. Radiography and computed tomography were used to measure local kyphotic angle and vertebral instability and to detect the presence of posterior wall fracture of the vertebral body. Correlations between clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft and radiographic findings were investigated. Results: Mean Numerical Rating Scale and Oswestry Disability Index were 7.4 and 58.0%, respectively. Delayed neurologic deficit occurred in 41 patients (19%). The mean local kyphotic angle, vertebral instability, and rate of posterior wall fracture of the vertebral body were 19.4 degrees, 7.3 degrees, and 91%, respectively. Numerical Rating Scale and Oswestry Disability Index were statistically correlated with vertebral instability but not with local kyphotic angle and presence of posterior wall fracture. In the patients with delayed neurologic deficit, vertebral instability was significantly higher and posterior wall fractures were significantly more frequent than in the patients without delayed neurologic deficit. Local kyphotic angle was not correlated with delayed neurologic deficit. Conclusions: Vertebral instability is a factor causing symptoms of osteoporotic vertebral fractures with intravertebral cleft. In addition, vertebral instability may be the predominant cause of delayed neurologic deficit. To manage osteoporotic vertebral fractures with intravertebral cleft and delayed neurologic deficit efficiently, it may be important to control vertebral instability of osteoporotic vertebral fractures.

- There is accumulating evidence for the role of fronto-striatal and associated circuits in obsessive–compulsive disorder (OCD) but limited and conflicting data on alterations in cortical thickness.AimsTo investigate alterations in cortical thickness and subcortical volume in OCD.MethodIn total, 412 patients with OCD and 368 healthy adults underwent magnetic resonance imaging scans. Between-group analysis of covariance of cortical thickness and subcortical volumes was performed and regression analyses undertaken.ResultsSignificantly decreased cortical thickness was found in the OCD group compared with controls in the superior and inferior frontal, precentral, posterior cingulate, middle temporal, inferior parietal and precuneus gyri. There was also a group x age interaction in the parietal cortex, with increased thinning with age in the OCD group relative to controls.ConclusionsOur findings are partially consistent with earlier work, suggesting that group differences in grey matter volume and cortical thickness could relate to the same underlying pathology of OCD. They partially support a frontostriatal model of OCD, but also suggest that limbic, temporal and parietal regions play a role in the pathophysiology of the disorder. The group x age interaction effects may be the result of altered neuroplasticity.
