This article reviews the literature concerning rheu-matic manifestations of inflammatory bowel disease (IBD),including common immune-mediated pathways,frequency,clinical course and therapy. Musculoskel-etal complications are frequent and well-recognized manifestations in IBD,and affect up to 33% of pa-tients with IBD. The strong link between the bowel and the osteo-articular system is suggested by many clinical and experimental observations,notably in HLA-B27 transgenic rats. The autoimmune pathogenic mechanisms shared by IBD and spondyloarthropathies include genetic susceptibility to abnormal antigen pre-sentation,aberrant recognition of self,the presence of autoantibodies against specific antigens shared by the colon and other extra-colonic tissues,and increased intestinal permeability. The response against microor-ganisms may have an important role through molecular mimicry and other mechanisms. Rheumatic mani-festations of IBD have been divided into peripheral arthritis,and axial involvement,including sacroiliitis,with or without spondylitis,similar to idiopathic anky-losing spondylitis. Other periarticular features can oc-cur,including enthesopathy,tendonitis,clubbing,peri-ostitis,and granulomatous lesions of joints and *** and osteomalacia secondary to IBD and iatrogenic complications can also occur. The manage-ment of the rheumatic manifestations of IBD consists of physical therapy in combination with local injection of corticosteroids and nonsteroidal anti-inflammatory drugs; caution is in order however,because of their possible harmful effects on intestinal integrity,perme-ability,and even on gut inflammation. Sulfasalazine,methotrexate,azathioprine,cyclosporine and lefluno-mide should be used for selected indications. In some cases,tumor necrosis factor-α blocking agents should be considered as first-line therapy.

BACKGROUND: Suspension trauma syndrome is a life-threatening event that occurs when a person is "trapped" in a prolonged passive suspension. It is most commonly seen in people who engage in occupational or sport activities that require harness suspension. The aim of this study is to identify the predisposing factors, pathophysiology, and management of suspension ***: A review and analysis of the literature published in English and Spanish from 1972 to 2020 on suspension trauma were performed. Search sources were Pub Med, Medline, Cochrane Library, MeSH, Up To Date, and Google Scholar. Articles referring to suspension trauma associated with other injury mechanisms(traumatic impact injuries, drowning, asphyxiation, or bleeding), case reports, and pediatric population were ***: Forty-one articles were identified. Of these, 29 articles related to mechanism, pathophysiology, and management of individuals who suffered prolonged suspension trauma without associated traumatic injuries were included in the study. We encountered several controversies describing the putative pathophysiology, ranging from blood sequestration in the lower extremities versus accumulation of metabolic waste and hyperkalemia to dorsal hook-type harness as a trigger cause of positional asphyxia;to vascular compression of femoral vessels exerted by the harness causing decreased venous return. Pstients suspended in a full-body harness with dorsal hook showed more hemodynamic alterations in response to the compressive effect on the rib cage, causing a reduction in perfusion by presenting a decrease in pulse pressure. Management strategies varied across ***: Progress has been made in individualizing the population at risk and in the management of suspension trauma. We recommend the formation of consensus definitions, larger cohort or registry studies to be conducted, and experimental animal models to better understand the mechanisms in order to develop management
