[Update on Gout and Calcium pyrophosphate deposition (CPPD)].

Dtsch Med Wochenschr 2018 Aug 7;143(16):1157-1166. Epub 2018 Aug 7.

The metabolic diseases gout and calciumpyrophosphate deposition (CPPD) (formerly: chondrocalcinosis/pseudogout) are crystal arthropathies which are caused by crystals in synovial fluid and in the case of gout also in periarticular structures. Today, in particular gout is considered as an auto-inflammatory process since phagocytosis of monosodium urate crystals by monocytes/macrophages results in the activation of the innate immune system by activation of the NRLP3-Inflammasome and consecutive secretion of the key cytokine interleukin-1ß and other pro-inflammatory cytokines. The prevalence of both crystal arthropathies rises with increasing age of patients. Read More

Differential diagnostic perspectives provided by en face microscopic examination of articular surface defects.

Clin Rheumatol 2018 Mar 4;37(3):831-836. Epub 2018 Feb 4.

Department of Vertebrate Paleontology, Carnegie Museum, Pittsburgh, PA, 15213, USA.

Surface defects have a central position in diagnosis of articular pathology. Recognizing the limitations of standard radiologic techniques and those imposed by positioning and averaging artifacts on CT evaluation, direct visualization of surface defects was pursued to identify disease characteristics that would facilitate interpretation of radiologic findings. Epi-illumination surface microscopy was utilized to examine macroscopically recognized articular surface defects in individuals in the Hamann-Todd, Terry, and Huntington human skeletal collections with previously verified diagnoses of rheumatoid arthritis, spondyloarthropathy, juvenile inflammatory arthritis (JIA), calcium pyrophosphate deposition disease (CPPD), gout, metastatic cancer, multiple myeloma, septic arthritis, tuberculosis, fungal arthritis, histiocytosis and sickle cell anemia (Rothschild and Rothschild Clin Infect Dis 20(5):1402-1408, 1995; Rothschild et al.

Examination of concomitant glenohumeral pathologies in patients treated arthroscopically for calcific tendinitis of the shoulder and implications for routine diagnostic joint exploration.

BMC Musculoskelet Disord 2017 Nov 21;18(1):476. Epub 2017 Nov 21.

Department of Orthopedics and Trauma Surgery, Medical Center - Albert-Ludwigs-University of Freiburg, Faculty of Medicine, Albert-Ludwigs-University of Freiburg, Hugstetter Strasse 55, 79106, Freiburg, Germany.

Background: Glenohumeral exploration is routinely performed during arthroscopic removal of rotator cuff calcifications in patients with calcific tendinitis of the shoulder (CTS). However, evidence on the prevalence of intraarticular co-pathologies is lacking and the benefit of glenohumeral exploration remains elusive. The aim of the present study was to assess and quantify intraoperative pathologies during arthroscopic removal of rotator cuff calcifications in order to determine whether standardized diagnostic glenohumeral exploration appears justified in CTS patients.

High-energy x-ray Talbot-Lau radiography of a human knee.

Phys Med Biol 2017 Aug 1;62(16):6729-6745. Epub 2017 Aug 1.

Erlangen Centre for Astroparticle Physics, Friedrich-Alexander-University Erlangen-Nuremberg, Erwin-Rommel-Strasse 1, 91058 Erlangen, Germany.

We report on a radiographic measurement of an ex vivo human knee using a grating-based phase-contrast imaging setup and a medical x-ray tube at a tube voltage of 70 kV. The measurement has been carried out using a Talbot-Lau setup that is suitable to achieve a high visibility in the energy regime of medical imaging. In a medical reading by an experienced trauma surgeon signatures of chondrocalcinosis in the medial meniscus have been identified more evidently using the dark-field image in comparison to the conventional attenuation image.

Coronary artery calcification: From crystal to plaque rupture.

Arch Cardiovasc Dis 2017 Oct 20;110(10):550-561. Epub 2017 Jul 20.

Department of Cardiology, Toulouse-Rangueil University Hospital, Toulouse University School of Medicine, TSA 50032, 31059 Toulouse cedex 9, France. Electronic address:

Epidemiological studies using coronary artery calcification measurement have linked calcification strongly with coronary events and mortality. Formerly considered as a passive age-related phenomenon, coronary artery calcification is now recognized as an active and regulated process. In fact, there is a local influence linked to the inflammation generated by the presence of oxidized lipids and, equally, a general influence from mineral metabolism factors, such as inorganic phosphate, calcium, pyrophosphate or fibroblast growth factor 23, which are regulators of cell differentiation and of phosphate and calcium deposition on the vascular layers.

Diagnostic modalities for distal radioulnar joint.

J Hand Surg Eur Vol 2017 May 14;42(4):395-404. Epub 2016 Dec 14.

1 Department of Radiology, Academic Medical Center, Amsterdam, The Netherlands.

The first imaging modality in patients suspected of distal radioulnar joint pathology should be conventional radiography to exclude or diagnose wrist pathology including osteoarthritis, rheumatoid arthritis, calcium pyrophosphate deposition disease, (healed) fractures, or impaction syndromes. When conventional radiography is inconclusive, high resolution 3 Tesla magnetic resonance imaging is advised. We provide a broad overview of the literature regarding the use of intra-articular contrast both with computed tomography (CTA) or magnetic resonance imaging (MRA). Read More
