ReA is common following Campylobacter infection, with an annual incidence of 4.3 per 100000. At the population level, acute ReA is mild, more frequent in adults, and not associated with HLA-B27. Besides C. jejuni, C. coli can trigger ReA.

At a mean follow-up of 5 yr, the current results show a favourable outcome in most patients with childhood onset jSSc and a significantly better survival than in the adult SSc patients.

A Prospective Study ILKKA KUNNAMO, PENTTI KALLIO, and PIRKKO PELKONEN The incidence of various types of arthritis in children was estimated by a prospective l-year study in the greater Helsinki area (population under 16 years of age: 148,362). Patients were sought from primary care physicians, and 71% of the patients studied were seen within 1 week of the onset of symptoms. All patients recehed followup care for at least 3 months; patients whose symptoms were prolonged received followup care for a minimum of 2 years. The incidence per 100,000 children under 16 years of age was as follows: 108.5 for all cases of arthritis, 6.7 for septic arthritis, 5.4 for enteropathic arthritis, 51.9 for transient synovitis of the hip, 18.9 for prolonged arthritis (duration >3 months), and 25.8 for acute transient arthritis. The incidence of juvenile rheumatoid arthritis was 19.6. Oligoarticular disease was prevalent (76%) among the juvenile rheumatoid arthritis patients.Few reports have been published regarding the incidence (1-7) and spectrum (8) of arthritis in children. Incidence studies are almost always concerned with juvenile rheumatoid arthritis (JRA) (1-5) and acute rheumatic fever (6-7). Little is known of the frequency of other types of arthritis in children.

The most frequent background for RP in children was the closure of ASD after the age of six years. Its course was unpredictable and often chronic, irrespective of the underlying cause or the therapy given. Colchicine did not prevent relapses.
