The diseases of the musculoskeletal system cover a wide range of pathological conditions; here diseases recorded in the HCCSCA are shown. Most connective tissue disorders belong the group of autoimmune disease with a common denominator of persistent, uncontrolled, immunologically mediated tissue damage of the joints, skin, kidney, blood vessels, etc (Hankins and Suarez, 2004). The major explanation of different autoimmune diseases such as rheumatoid arthritis or systemic lupus erythematosus is that the immune system loses its ability to discriminate between self and non-self cells. There is a predominance of autoimmune disease among women, during pregnancy some of these diseases improve or worsen, in addition most of these diseases exacerbate after delivery, during the postpartum period.
