Pulmonary Mycobacterium Spindle Cell Pseudotumor in Patient With Liver Transplant.
We report a case of liver transplant patient who presented with lung masses, found to be Mycobacterium spindle cell pseudotumors. The masses demonstrated hypermetabolic activities on positron emission tomography. Core biopsy revealed sheets of spindle histiocytic cells with abundant acid-fast bacilli identified as Mycobacterium avium-intracellulare complex. ⋯ Histopathology illustrating the proliferation of spindle cell shaped histiocytes containing numerous acid-fast bacilli is the gold standard for diagnosis. The standard treatment has not been well established; previously reported cases followed the standard treatment for Mycobacterium based on organ involvement. Our case is the first case to our knowledge that reports pulmonary Mycobacterium spindle cell pseudotumors in a liver transplant recipient.

Girolamo Fabrici d'Acquapendente and the Oplomochlion: The Several Applications of an Effective Rehabilitation Tool.
Girolamo Fabrici d'Acquapendente (1533-1619) was an Italian anatomist, surgeon and physiologist and a protagonist of the scientific revolution of the Renaissance. He made anatomy a scientific discipline and is justly considered a precursor of modern orthopaedics. ⋯ He ascribed the pathogenesis of the equinovarus supinated foot to the position taken by the foot of the fetus during intrauterine life. The Oplomochlion, shown in the Operationes chirurgicae and attributed to Fabrici, is actually a collection of very diverse orthotic, prosthetic and surgical metal instruments invented by Fabrici and arranged with a demonstrative purpose and a topographic criterion, as if on an exhibition dummy.

The purpose of this study was to demonstrate the role of renin-angiotensin system (RAS)-related components, vascular endothelial growth factor (VEGF) and atrial metalloproteinase-13 (MMP-13) in synovial tissue and synovial fluid from patients with rheumatoid arthritis (RA) and osteoarthritis (OA). ⋯ The present results suggest that RAS-related components in RA and OA, including renin, ACE, angiotensin type 1 and type 2 receptors, are associated with increased expression of VEGF and play an important role in angiogenesis. Furthermore, there was a significant positive correlation between the expression of VEGF and MMP-13.

Sortilin, a pluripotent peptide hormone, plays a role in glucose and lipid metabolism. A link between sortilin and insulin sensitivity has been implicated. However, the clinical implications of this link remain elusive. Our aims were to investigate whether sortilin levels were altered in subjects with newly diagnosed type 2 diabetes mellitus (nT2DM) compared with subjects with normal glucose tolerance (NGT) and to determine whether a link exist between sortilin levels and metabolic parameters. ⋯ Decreased circulating levels of sortilin were associated with unfavorable metabolic profiles in subjects with nT2DM.

Hyperuricemia is associated with the development, progression and outcome of several diseases. The purpose of this study is to evaluate the serum uric acid (UA) levels as a predictor of long-term mortality in an older population (age 60 years and above). ⋯ Elevated levels of UA in older patients in acute settings is a predictor of long-term mortality.
