Increased expression of carbonic anhydrase I in the synovium of patients with ankylosing spondylitis

Background  

One of the most distinctive features of ankylosing spondylitis (AS) is new bone formation and bone resorption at sites of chronic inflammation. Previous studies have indicated that the hyperplasia and inflammation of synovial tissues are significantly related to the pathogenic process of AS. The present study used a proteomic approach to identify novel AS-specific proteins by simultaneously comparing the expression profiles of synovial membranes from patients with AS, rheumatoid arthritis (RA) and osteoarthritis (OA).     

Comparison of electrode location between immediate postoperative day and 6 months after bilateral subthalamic nucleus deep brain stimulation

Objective  

We compared the electrode positions of subthalamic nucleus (STN) deep brain stimulation (DBS) estimated at the immediate postoperative period with those estimated 6 months after surgery.     

Sciaticum majus foramen and sciaticum minus foramen as the path of SWL in the supine position to treat distal ureteral stone

The purpose of the study is to evaluate the efficacy and safety of shock wave lithotripsy (SWL) using sciaticum majus foramen and sciaticum minus foramen as the path to treat distal ureteral stone in supine position. Between December 2006 and November 2008, 243 cases of distal urinary calculi were treated in our department using SWL or ureteroscopy. 189 cases for SWL were treated in supine position. The shockwave target on the stone in distal ureter via sciaticum majus foramen and sciaticum minus foramen, avoiding the sacroiliac joint. 54 cases were underwent ureteroscopy combined with holmium:YAG laser lithotripsy. The stone-free rate and the efficacy quotient (EQ) for SWL and ureteroscopy was 81.5%, 0.68; 94.4%, 0.78; respectively (p = 0.02). The retreatment rate for SWL and ureteroscopy was 14.6%, 0, respectively. The number of the shocks ranged from 600 to 3,000 (mean 2,566.3 ± 378.8). The energy per pulse of SWL ranged from 8 to 12 kV (mean 10.7). SWL in the supine position using sciaticum majus foramen and sciaticum minus foramen as the path is a choice of the treatment of distal ureteral stones with an excellent success rate and low side effect.     

Prognostic value of pathologic fracture in patients with high grade localized osteosarcoma: A systemic review and meta‐analysis of cohort studies

Consensus has not been reached regarding the ability of pathologic fracture to predict local recurrence and survival in osteosarcoma. We aim to review the available evidence to examine the association between pathologic fracture and osteosarcoma prognosis. A comprehensive literature search for relevant studies published until March 2014 was performed using PubMed, Cochrane and Web of Science. The studies investigating pathologic fracture of osteosarcoma patients were systematically analyzed. The overall relative risk (RR) was estimated using a fixed‐effect model or random‐effect model according to heterogeneity between the trials. We included nine cohort studies involving 2,187 patients (311 with pathologic fracture and 1,876 without fracture) for the analysis of survival rate and local recurrence. Studies were assessed for quality using the Newcastle–Ottawa Assessment Scale. In the fixed‐effects model, the meta‐analysis showed that pathologic fracture in osteosarcoma patients predicted poor 3‐year overall survival (OS) (RR = 1.86, 95% CI: 1.37–2.53, p < 0.001) and 5‐year OS (RR = 1.34, 95% CI: 1.06–1.70, p = 0.016). Similarly, pathologic fracture was significantly correlated with worse 3‐year event free survival (EFS) (RR = 1.52, 95% CI: 1.21–1.92, p < 0.001) and 5‐year EFS (RR = 1.24, 95% CI: 1.03–1.49, p = 0.021), whereas no significant association was noted with local recurrence (RR = 1.30, 95% CI: 0.84–2.02, p = 0.233). The meta‐analysis confirmed that pathologic fracture in osteosarcoma was a prognostic marker for both OS and EFS but not for local recurrence. © 2014 Orthopaedic Research Society.

The laboratory performance of the enFLOW®, buddy lite™ and ThermoSens® fluid warmers

We measured heating of isotonic saline by three fluid warmers in six experiments: saline at 5 °C or 20 °C delivered at 30, 50 or 100 ml.min^?1. At the three flow rates, the enFLOW^®, buddy lite^? and ThermoSens^® systems heated 5 °C saline to mean (SD) temperatures of: 41.1 (0.5) °C, 37.7 (0.6) °C and 39.1 (0.6) °C; to 40.3 (0.8) °C, 33.9 (1.6) °C and 39.3 (0.7) °C; and to 37.1 (0.8) °C, 24.0 (1.3) °C and 37.6 (1.0) °C, respectively, p < 0.0001 for each experiment. The mean (SD) times taken to heat 5 °C saline were: 16.6 (1.7) s, 258.4 (58.9) s and 134.2 (79.6) s; 16.9 (1.8) s, 256.2 (62.2) s and 182.5 (74.5) s; and 21.5 (1.5) s, 275.9 (49.3) s and 313.5 (18.0) s, respectively, p < 0.0003 for each experiment. The results for saline at 20 °C were similar. The enFLOW system heated saline above 36 °C faster than the ThermoSens system, whereas the buddy lite often failed to achieve 36 °C.
