Implant failure of the Compress prosthesis: a case report.
J Med Case Rep
January 2025
Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine, Nagoya University Hospital, 65 Tsurumai, Showa, Nagoya, Aichi, 466-8550, Japan.
Background: The Compress is designed to achieve bone formation and stability by applying pressure at the bone-implant interface, minimizing the likelihood of aseptic loosening, which is a complication of stem implants. Herein, we report two cases of implant failure using the Compress.
Case Presentation: Case 1 describes a 36 year-old Japanese man who underwent extraarticular tumor resection, Compress arthroplasty, and reconstruction with a gastrocnemius flap after preoperative chemotherapy for a secondary malignant giant cell tumor in the right distal femur.
Clinical, laboratory, and orbital imaging features of giant cell arteritis in comparison to non-arteritic anterior ischemic optic neuropath: a single center case series.
Front Ophthalmol (Lausanne)
December 2024
Department of Ophthalmology & Visual Sciences, School of Medicine, Washington University in St. Louis, St Louis, MO, United States.
Background: Giant cell arteritis (GCA) is the most common vasculitis in patients older than 50 years and is considered a "do not miss" diagnosis. However, it remains a diagnostic challenge given overlapping clinical syndromes such as non-arteritic anterior ischemic optic neuropathy (NAION) and poorly explored imaging findings.
Materials And Methods: In this retrospective study between the time period of January 2013 and December 2021, a total of 13 consecutive patients with a pathological diagnosis of GCA and 8 patients with clinical diagnosis of NAION were isolated.
Magnetotactic bacteria from diverse Pseudomonadota families biomineralize intracellular Ca-carbonate.
ISME J
January 2025
Université Aix-Marseille, CNRS, CEA, UMR7265 Institut de Biosciences and Biotechnologies d'Aix-Marseille, CEA Cadarache, F-13108 Saint-Paul-lez-Durance, France.
Intracellular calcium carbonate formation has long been associated with a single genus of giant Gammaproteobacteria, Achromatium. However, this biomineralization has recently received increasing attention after being observed in photosynthetic Cyanobacteriota and in two families of magnetotactic bacteria affiliated with the Alphaproteobacteria. In the latter group, bacteria form not only intracellular amorphous calcium carbonates into large inclusions that are refringent under the light microscope, but also intracellular ferrimagnetic crystals into organelles called magnetosomes.

Arthritis Res Ther
January 2025
Rheumatology Department, Hospital Universitario Marqués de Valdecilla. IDIVAL Immunopathology group, Santander, Spain.
Objectives: To compare mortality rates between GCA patients and the general population in Spain, and to identify associated factors influencing mortality.
Methods: ARTESER, a multicenter registry by the Spanish Society of Rheumatology, includes GCA patients from June 2013 to March 2019. Demographic, clinical, imaging, histological and mortality data were collected retrospectively.
Keratin Positive Giant Cell Rich Tumor of the Pelvic Bone with a Fusion: A Case Report.
Int J Surg Pathol
January 2025
Department of orthopedic oncology, UZ Leuven, Leuven, Belgium.
Keratin positive giant cell rich tumor is a rare mesenchymal tumor first described in 2025. It can occur in both soft tissue and bone and predominantly affects young women. The tumor's biological behavior remains uncertain despite its low-grade classification.
