Adenosine triphosphate: a new player in complex regional pain syndrome type 1.

The complex regional pain syndrome type 1 (CRPS-1) is one of the most discussed painful syndromes due to the variability and severity of its symptoms. CRPS-1 generally occurs after a trauma, a fracture or a sprain followed by an immobilization. Classical diagnostic criteria are not always clear; hence, the diagnosis is difficult.

Intra-articular clodronate in patients with knee osteoarthritis non-responder to intra-articular hyaluronic acid - a case report series of 9 patients with 8-month follow-up.

Background: Osteoarthritis (OA) is a common disease in the elderly people, inducing pain and functional limitations. Clodronate (CLO) a first generation non-nitrogen containing bisphosphonate has been purposed as a treatment of OA, being effective on pain, inflammation, bone marrow oedema, osteophytosis and cartilage regeneration. Intra-muscular routes of CLO showed efficacy in the treatment of Knee OA (KOA) and erosive OA of the hand.

Mesenchymal Cells are a Promising -But Still Unsatisfying- Anti- Inflammatory Therapeutic Strategy for Osteoarthritis: A Narrative Review.

Osteoarthritis (OA) is a chronic disease with both degenerative and inflammatory characteristics, affecting the osteochondral unit with the involvement of cartilage, subchondral bone and periarticular tissues. OA can produce chronic pain with neuropathic and inflammatory characteristics, leading to an increased disability. OA is secondary to many predisposing factors where the inflammatory process plays a key role.

Bone Marrow Edema: pathogenetic features.

The term "bone marrow edema" was used for the first time in 1988 by Wilson. He noticed a high signal on fluid-sensitive sequences at MRI located in the subchondral bone. We can find bone marrow edema in many musculoskeletal diseases such as Inflammatory and Rheumatic diseases (Rheumatoid Arthritis, Spondylarthritis, etc.
