Evaluation of hypervascularity in synovitis of the shoulder using ultrasound: comparison of preoperative ultrasound findings and intraoperative arthroscopic findings.

Background: Synovitis of the shoulder causes pain; however, it is difficult to accurately determine the area and degree of synovitis from preoperative images. This study investigated the correlation between intraoperative arthroscopic findings and preoperative power Doppler ultrasonography (PDUS) findings for synovitis evaluation.

Methods: Forty patients (mean age = 62.

2,5-Furandicarboxylic acid production from furfural by sequential biocatalytic reactions.

2,5-Furandicarboxylic acid (FDCA) is a valuable compound that can be synthesized from biomass-derived hydroxymethylfurfural (HMF), and holds great potential as a promising replacement for petroleum-based terephthalic acid in the production of polyamides, polyesters, and polyurethanes used universally. However, an economical large-scale production strategy for HMF from lignocellulosic biomass is yet to be established. This study aimed to design a synthetic pathway that can yield FDCA from furfural, whose industrial production from lignocellulosic biomass has already been established.

The use of a bioactive bone cement containing apatite-wollastonite glass-ceramic filler and bisphenol-a-glycidyl methacrylate resin for acetabular fixation in total hip arthroplasty: long-term follow-up results of a clinical trial.

Aims: In the 1990s, a bioactive bone cement (BABC) containing apatite-wollastonite glass-ceramic (AW-GC) powder and bisphenol-a-glycidyl methacrylate resin was developed at our hospital. In 1996, we used BABC to fix the acetabular component in primary total hip arthroplasty (THA) in 20 patients as part of a clinical trial. The purpose of this study was to investigate the long-term results of primary THA using BABC.

Temporary total hip arthroplasty-like spacer for treating an infected periprosthetic femoral fracture using a long stem: A case report.

Introduction: Infected periprosthetic femoral fractures are among the most complex and significant complications of total hip arthroplasty (THA). We report the novel use of a temporary THA-like spacer for treating an infected periprosthetic femoral fracture after revision surgery using a long stem.

Case Presentation: We present a 72-year-old woman sustained a left infected periprosthetic femoral fracture after revi - streptococci in the culture sample.

Couch height-based patient setup for abdominal radiation therapy.

There are 2 methods commonly used for patient positioning in the anterior-posterior (A-P) direction: one is the skin mark patient setup method (SMPS) and the other is the couch height-based patient setup method (CHPS). This study compared the setup accuracy of these 2 methods for abdominal radiation therapy. The enrollment for this study comprised 23 patients with pancreatic cancer.
