ATP‐induced chondrocalcinosis [PDF]

Arthritis & Rheumatism, 1992
AbstractObjective. To determine whether adult articular cartilage mineralizes in the presence of ATP.Methods. Intact adult porcine articular cartilage and monolayers of chondrocytes were cultured in physiologic media containing ATP, and mineralization was measured as retention of 45Ca. Cartilage was analyzed by electron microscopy.Results.

Crowned Dens Syndrome Mimicking Atlantoaxial Infection in a Patient With Systemic Sclerosis: A Case Report

Case Reports in Rheumatology, Volume 2026, Issue 1, 2026.
Objective Crowned dens syndrome (CDS), caused by calcium pyrophosphate or hydroxyapatite deposition around the odontoid process, is an under‐recognized cause of acute severe neck pain and headache. It can closely mimic septic arthritis, osteomyelitis, giant cell arteritis (GCA), polymyalgia rheumatica (PMR), or cervical spondylitis. We report a case of

Polyarticular and familial chondrocalcinosis [PDF]

Arthritis & Rheumatism, 1970
AbstractFrom our series of 72 patients with articular chondrocalcinosis, 37 who presented polyarticular involvement are described. Twenty‐eight patients, including 19 aggregated within different family groups, are natives of the Chiloé island group. Members of 1 of the 6 families had unusually severe disease with deformities, and 1 had bony ankylosis ...

Further Evidence That Chondrocalcinosis 1 (CCAL1) is a Confirmed Mendelian Phenotype With a Known Molecular Basis

American Journal of Medical Genetics Part A, Volume 197, Issue 12, December 2025.
ABSTRACT Chondrocalcinosis (CCAL), also known as calcium pyrophosphate dihydrate deposition disease (CPPDD), is a frequent multifactorial condition in the elderly, but there are two rare autosomal dominant Mendelian forms, CCAL1 (OMIM %600668) and CCAL2. Only three families with molecularly proven CCAL1 have been reported.

Recurrent Nephrolithiasis and Beyond: The Long Diagnostic Odyssey of a Case of CLDN16 Mutation

Clinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT Familial Hypomagnesemia with Hypercalciuria and Nephrocalcinosis (FHHNC) is a rare tubulopathy resulting from mutations in the CLDN16 and CLDN19 genes. The affected individuals commonly present with polyuria, polydipsia, excessive urinary magnesium (Mg) and calcium (Ca) wasting, nephrocalcinosis, nephrolithiasis, recurrent urinary tract ...

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

Advanced Healthcare Materials, Volume 14, Issue 23, September 8, 2025.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...
