Psoriatic arthritis is a condition where psoriasis -- a chronic inflammatory skin disorder -- occurs along with joint inflammation. It is responsible for eight to twenty percent of cases of arthritis in children, according to WebMD's Emedicine Health site. In many children, just one joint will be affected, but other cases will involve pain in multiple joints. Juvenile psoriatic arthritis may cause bone growth problems later in life. It's important to learn the symptoms of this disease so treatment can start early.
Cushing's syndrome is a rare hormonal disorder caused when there is too much of the hormone cortisol in your body. While it is most common in adults, it can affect children.
Out of every 100,000 children and teens, between 10 and 20 experience the joint inflammation, pain, swelling and stiffness of juvenile rheumatoid arthritis (JRA). Polyarticular juvenile rheumatoid arthritis is one form of the disease that affects five or more of a child's joints. Girls are much more susceptible to develop this type of JRA, and children who have these arthritis symptoms also tend to experience vision problems and anemia. Rheumatologists treat polyarticular JRA with prescription medications.
