Division of Aging Research, Gwangju Center, Korea Basic Science Institute (KBSI), 49 Dosicheomdansaneop-ro, Nam-gu, Gwangju, 61751, South Korea.

Optical diffraction tomography (ODT) enables imaging of unlabeled intracellular components by measuring the three-dimensional (3D) refractive index (RI). We aimed to detect intracellular monosodium urate (MSU) crystals in synovial leukocytes derived from gout patients using ODT. The 3D RI values of the synthetic MSU crystals, measured by ODT, ranged between 1. Read More

Coronavirus disease 2019 (COVID-19)-associated constrictive pericarditis.

BMJ Case Rep 2021 May 11;14(5). Epub 2021 May 11.

Division of Cardiology and Department of Radiology, George Washington University School of Medicine, Washington, DC, USA.

This report documents a rare case of COVID-19-associated constrictive pericarditis (CP) in the setting of a recent COVID-19 infection. A 55-year-old man with a history of hypertension and gout presented with acute hypoxic respiratory failure and was diagnosed with COVID-19 pneumonia with progression to acute respiratory distress syndrome. His hospital course was complicated by a large pericardial effusion; an emergent bedside transthoracic echocardiography was concerning for cardiac tamponade, so pericardiocentesis was performed.

Gouty tophus presenting as an anterior cruciate ligament mass in the knee: Case report and brief review of relevant literature.

Int J Surg Case Rep 2021 Apr 27;82:105920. Epub 2021 Apr 27.

Michael Garron Hospital, Toronto, ON, Canada; University of Toronto, Toronto, ON, Canada.

Introduction And Importance: Tophacious gout presenting at the anterior cruciate ligament (ACL) is extremely rare and difficult to differentiate from other intraarticular pathology. This is mainly due to conventional diagnostic tools, such as MRI, producing ambiguous results versus pigmented villonodular synovitis (PVNS) and ganglion cysts.

Case Presentation: Here we report an individual in their late-20s with a gouty tophus located at the origin of the ACL in the knee. Read More

Open Popliteal Tendon Repair.

Arthrosc Tech 2021 Feb 30;10(2):e499-e505. Epub 2021 Jan 30.

The Steadman Clinic, Vail, Colorado, U.S.A.

Popliteal tendon tears without concomitant damage to the cruciate ligaments or other posterolateral corner ligaments are rare entities with few studies reporting on their existence, with rare case reports discussing their treatment. Continued pain, instability, and effusions are typical symptoms, with magnetic resonance imaging being the main tool for diagnosis. Furthermore, monosodium urate crystals that induce gout have been shown to collect in the popliteal groove and thus may lead to degeneration and isolated tearing. Read More

Dr. Diogo de Faria 1379, Vila Clementino, São Paulo, SP 04037-005, Brazil (J.E.C.A., S.R.N.C., A.K.T., F.N.C., A.Y.S., A.Y.A.); Division of Musculoskeletal Radiology, Alta Diagnósticos, São Paulo, Brazil (J.E.C.A., S.R.N.C., A.K.T., A.Y.S.); Musculoskeletal Imaging Division, Hospital Israelita Albert Einstein, São Paulo, Brazil (A.K.T.); Department of Diagnostic Imaging, Federal University of São Paulo, São Paulo, Brazil (F.N.C., A.Y.A.); Division of Musculoskeletal Radiology, Hospital do Coração (HCor), São Paulo, Brazil (A.K.T., A.Y.S.); and Teleimagem, São Paulo, Brazil (A.K.T., A.Y.S.).

Spinal pain due to facet joint disease is difficult to diagnose since the clinical history and physical examination findings are usually nonspecific. Facet joint disorders have a wide range of causes and, because of the potential for chronic back pain and disability, an accurate diagnosis is essential. The most frequent cause of pain in facet joints is osteoarthritis, which can be assessed at radiography, CT, or MRI. Read More
