Ahmed Barakat

CNS Drugs 2019 Apr 19. Epub 2019 Apr 19.

Department of Medical Pharmacology, Faculty of Medicine, Assiut University, Assiut, 71515, Egypt.

Tramadol-an atypical opioid analgesic-has a unique pharmacokinetic and pharmacodynamic profile, with opioidergic, noradrenergic, and serotonergic actions. Tramadol has long been used as a well-tolerated alternative to other drugs in moderate pain because of its opioidergic and monoaminergic activities. However, cumulative evidence has been gathered over the last few years that supports other likely mechanisms and uses of tramadol in pain management. Read More

Extracellular Vesicles in the Synovial Joint: Is there a Role in the Pathophysiology of Osteoarthritis?

Malays Orthop J 2019 Mar;13(1):1-7

Swansea University Medical School, Swansea University, Swansea, United Kingdom.

The role of extracellular vesicles (EV) in osteoarthritis has become the focus of much research. These vesicles were isolated from several cell types found in synovial joint including chondrocytes and synovium. As articular cartilage is an avascular tissue surrounded by synovial fluid, it is believed that EV might play a crucial role in the homeostasis of cartilage and also could hold key information in the pathogenesis of osteoarthritis.

Automatic MRI-based Three-dimensional Models of Hip Cartilage Provide Improved Morphologic and Biochemical Analysis.

Clin Orthop Relat Res 2019 May;477(5):1036-1052

F. Schmaranzer, R. Helfenstein, T. D. Lerch, K. A. Siebenrock, M. Tannast, Department of Orthopaedic Surgery, Inselspital Bern, University of Bern, Switzerland, Bern, Switzerland G. Zeng, G. Zheng, Institute for Surgical Technology and Biomechanics, University of Bern, Switzerland, Bern, Switzerland F. Schmaranzer, E. N. Novais, J. D. Wylie, Y-J. Kim, Department of Orthopaedic Surgery, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA.

Background: The time-consuming and user-dependent postprocessing of biochemical cartilage MRI has limited the use of delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). An automated analysis of biochemical three-dimensional (3-D) images could deliver a more time-efficient and objective evaluation of cartilage composition, and provide comprehensive information about cartilage thickness, surface area, and volume compared with manual two-dimensional (2-D) analysis.

Questions/purposes: (1) How does the 3-D analysis of cartilage thickness and dGEMRIC index using both a manual and a new automated method compare with the manual 2-D analysis (gold standard)? (2) How does the manual 3-D analysis of regional patterns of dGEMRIC index, cartilage thickness, surface area and volume compare with a new automatic method? (3) What is the interobserver reliability and intraobserver reproducibility of software-assisted manual 3-D and automated 3-D analysis of dGEMRIC indices, thickness, surface, and volume for two readers on two time points?

Methods: In this IRB-approved, retrospective, diagnostic study, we identified the first 25 symptomatic hips (23 patients) who underwent a contrast-enhanced MRI at 3T including a 3-D dGEMRIC sequence for intraarticular pathology assessment due to structural hip deformities. Read More

Biosci Rep 2019 Apr 17. Epub 2019 Apr 17.

Xiangya Hospital, Central South University, Changsha, China.

Osteoarthitis (OA) is the most common aging-related joint pathology; the aging process results in changes to joint tissues that ultimately contribute to the development of OA. Articular chondrocytes exhibit an aging-related decline in their proliferative and synthetic capacity. Sirtuin 1 (SIRT 1), a longevity gene related to many diseases associated with aging, is a NAD+-dependent protein deacetylase and master metabolic regulator. Read More

Proof of Concept: Hip Joint Damage Occurs at the Zone of Femoroacetabular Impingement (FAI) in an Experimental FAI Sheep Model.

Osteoarthritis Cartilage 2019 Apr 13. Epub 2019 Apr 13.

Department of Orthopaedic Surgery, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland; Musculoskeletal Research Unit (MSRU), Equine Hospital, Vetsuisse Faculty, University of Zürich, Zürich, Switzerland; Department of Orthopaedic Surgery and Traumatologie, Cantonal Hospital, University of Fribourg, Switzerland.

Objective: In ovine hips chondrolabral damage as seen in cam-type femoroacetabular impingement (FAI) can be induced via an intertrochanteric varus osteotomy. However, it is yet to proven whether the observed cartilage damage is caused by a dynamic cam type impingement. Thus we asked, (1) whether actual cartilage damage observed after FAI induction in ovine hips occurs at the predicted, computed zone of FAI; (2) whether the extent of cartilage damage increases with ambulation time in this animal model?

Design: In this experimental, controlled, comparative study 20 sheep underwent unilateral FAI induction through an intertrochanteric varus osteotomy. Read More
