Introduction: As the number of revision total knee arthroplasties (rTKA) continues to rise, there is increasing interest in the use of contemporary rotating hinge prostheses. These devices often incorporate porous cones to fill bone defects and enhance long-term fixation. This study evaluated the clinical and functional outcomes and survivorship in rTKA patients utilizing a rotating hinge prosthesis with flexible titanium (FT) cones, porous tantalum (PT) cones, or no cones.

: Classical reverse shoulder arthroplasty (RSA) with a high neck-shaft angle (NSA) of 155° has shown satisfactory outcomes. However, newer RSA designs aim to improve results by modifying the stem design. This study evaluates the 5-year outcomes of a stem design featuring a rectangular metadiaphyseal fixation and a 135° NSA.

Objective: The objective of this study was to evaluate autologous platelet-rich fibrin (PRF) membrane weights and measurements after production by different centrifuges. Moreover, the values obtained with blood cellular components were correlated.
Methods: Twelve systemically healthy participants underwent dental implant surgery associated with PRF membranes as the graft biomaterial at the implant site.
Serial cerebrospinal fluid concentrations of high mobility group box 1 in bacterial meningitis: a retrospective cohort study.

Department of Pediatrics, Yamaguchi University Graduate School of Medicine, 1-1-1 Minamikogushi, Ube, Yamaguchi, 755-8505, Japan.
Background: Bacterial meningitis (BM) is a life-threatening central nervous system infection with potential for severe neurological sequelae. High mobility group box 1 (HMGB1) is known as a late inflammatory mediator associated with lethal pathology. This study aims to investigate the serial cerebrospinal fluid (CSF) concentrations of HMGB1 in children with BM and its relationship to neurological prognosis.

Objective: To investigate the clinical utility of novel of new hematological markers in the preoperative diagnosis of periprosthetic joint infection (PJI).
Methods: A retrospective analysis was conducted on a total of 149 patients who underwent revision of total hip arthroplasty (THA) or total knee arthroplasty (TKA) at a single center between January 2016 and June 2022, including 63 males and 86 females, aged from 47 to 93 years old with an average of (69.5±11.
