Giant cell tumor of bone (GCTB) is a locally aggressive benign neoplasm that is associated with a large biological spectrum ranging from latent benign to highly recurrent and occasionally metastatic tumor. In this article, we present a case of a 37-year-old woman who presented with fracture at the distal femur due to GCTB. Bone segment resection and reconstruction were done, and histopathology showed tumor features for GCTB. Later, multiple lung metastasis was found 22 months post-operation, which was verified by biopsy. Then systemic denosumab therapy with different intervals (1-month and 2-month) was tried as the treatment. It was clarified that monthly denosumab administration, instead of 2-month interval, was required to control the progression of the unresectable multiple lung metastasis from GCTB, which could be a choice for the future treatment of these patients.

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.

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.

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.
