Manifestations: acute and chronic inflammation, fever, pain, necrotic (rotting) bone o Treatment: antibiotic, debridement, surgery, hyperbaric oxygen therapy Osteoporosis o Condition of holes in the bone—porous bone, poorly mineralized o Demonstrated by reduced bone mass/density and imbalance of bone resorption and formation o Bone histology is usually normal, but it lacks structural.

Noninvasive mechanical joint loading (MJL) has been used as an alternative model for the pain associated with osteoarthritis (OA), inducing both OA lesions and a reproducible pain phenotype that can be reversed with the use of known analgesics for OA pain, according to data published in Arthritis & Rheumatology.. The investigators sought to characterize and pharmacologically test the pain. • Joint disease is common and, in fact, WHO ranks musculoskeletal disorders as the most frequent cause of disability in the modern world. • Pain is the predominant symptom but is frequently associated with fatigue, which may be disabling • Pain is classically nociceptive due to mechanical or inflammatory joint In light of these antecedents, we aimed to compare the sensitivity of grip strength in mice with joint inflammation vs. inflammatory tactile allodynia to the effects of several analgesic drugs of different pharmacological classes, and tested whether the appearance of grip strength deficits and tactile allodynia arose from the same mechanisms. 2 While RA pain is often viewed simply as a direct consequence of inflammation, pain and inflammation are at least partially uncoupled in RA (5, 6).
