Pediatric Clinical manifestations of rheumatoid

Can occur at any age, But in 2 to 4-year-old and 8 to 10 years of age incidence up. Women more than men. There are 3-onset: A body type more common in young children, women and men may get sick. Mainly fever, rash, arthritis and other organ involvement symptoms. Fever was flip-hot type, one day, there will be one or two peaks, high fever up to 40 ° C above the daily fluctuations up 3 to 4 ° C, shivering with fever before. During heat illness heavier, thermal children back normal circumstances turned for the better. Fever sustainable few weeks or a few months, often spontaneous remission, but easy to relapse. Accompanied rash during fever, rash was pleomorphic, scattered ranging from the size of erythema, dual-can be integrated into, or submission annular erythema, skin rash appeared quite short, easy to relapse, common to the trunk can be seen at plantar limbs, and even palms. Arthritis symptoms generally lighter, and more performance for multi-joint involvement, there are no joint symptoms. Many children with varying degrees of liver, spleen, lymph nodes. There are a small number of cases, pleurisy, pericarditis or myocarditis. Second, multiple joints of this type of performance similar to adult rheumatoid arthritis, started only 1 ~ 2 joint involvement, as early migration of becoming more fixed symmetry arthritis. The main facet of this type of the characteristics of the proximal interphalangeal joint disease most often, followed by the metacarpophalangeal and toe joints, the joints can also be involved if the knee, ankle, wrist, elbow, hip, spine, especially the cervical spine, and other joints . More slow onset of this type, the incidence of intense minorities. In early partial pain, morning stiffness, after joint swelling, heat, pain, gradually turned into a spindle, activities restricted, knee, elbow, means, wrist was fixed flexion. Only a small number of cases not swollen pain without swelling or pain. Muscle cramps near the joints, and then a decline, which finally led to the deformation caused lesions joint deformity and stiffness, joint deformation was particularly prevalent in the six months to a year after the onset, that is, reduce the pain at this time. If other parts of the body such as the joint involvement can cause cervical neck pain and stiffness, temporomandibular joint involvement often caused chewing obstacles. Minor systemic symptoms, only low heat, fatigue, decreased appetite, mild anemia and mild liver, spleen, lymph nodes. Minority children in the vicinity of a joint subcutaneous nodules. Rheumatoid factor for the positive. Third, single-articular joints involved only a small number (often one), mainly involving large joints such as the knee, ankle, elbow and other places. Joints may be a chronic inflammatory process or repeated seizures, but rarely cause serious joint activities restricted. This type of joint involvement in a small number of cases at the same time or after a iridocyclitis can sometimes be the first symptom of this type. Minor systemic symptoms may have low heat, weakness, mild anemia and liver and spleen enlarged lymph nodes.
