Also, fibromyalgia is a psychosomatic condition marked by widespread pain and tenderness. This study included 400 patients attended certain outpatient clinics of\u00a0Rheumatology in Egypt and Saudi Arabia, who were not fulfilling criteria for RA diagnosis. Criteria for classification of fibromyalgia syndrome were applied to all patients. We did lab tests and radiological imaging modalities for diagnosis or exclusion of suspected diseases were applied. All patients were fulfilling both old and new criteria of fibromyalgia syndrome, and not fulfilling any RA criteria, and had vitamin D3 deficiency or insufficiency. 75% of patients had abnormally high levels of PTH, without parathyroid gland pathology. Radiology showed subperiosteal and subchondral resorption of mainly thumbs, subchondral osteopenia of proximal and middle phalanges, mild subperiosteal resorption along the radial aspect of the middle phalanx and mild tuft erosions, besides changes in the carpus closely resembling those of rheumatoid arthritis, of ulnar styloid resorption, radiocarpal and scapho-trapezoid joint arthritis. Of special interest, the presence of tuft spur-like excrescences.<\/jats:p>","DOI":"10.1038\/s41598-021-01698-1","type":"journal-article","created":{"date-parts":[[2021,11,15]],"date-time":"2021-11-15T11:03:36Z","timestamp":1636974216000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["RETRACTED ARTICLE: Middle east pain syndrome is a pollution-induced new disease mimicking rheumatoid arthritis"],"prefix":"10.1038","volume":"11","author":[{"given":"Adel A.","family":"Elbeialy","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdlnby M.","family":"Bauomi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Basma M.","family":"Elnaggar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hala M.","family":"Elzomor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,11,15]]},"reference":[{"key":"1698_CR1","doi-asserted-by":"publisher","first-page":"387","DOI":"10.1159\/000209740","volume":"27","author":"JG Taylor","year":"2009","unstructured":"Taylor, J.
