Prevalence of rheumatoid arthritis in Serbia.

The aim of this study was to estimate the prevalence of rheumatoid arthritis (RA) in Serbia, using the European EULAR project methodology. In a detection phase, a previously translated and validated telephone Questionnaire was used by lay interviewers on 6,213 randomly selected telephone numbers representing urban population from four Serbian towns: Belgrade (north), Cacak, Uzice and Krusevac (south). Patients with suspected RA were called again by a rheumatologist.

Psoriatic arthritis classification criteria: Moll and Wright, ESSG and CASPAR -- a comparative study.

Objectives: to evaluate and compare Moll and Wright, ESSG and CASPAR criteria for psoriatic arthritis (PsA) classification.

Patients And Methods: Study comprised 356 patients (pts): 120 PsA pts in the investigated group, 123 pts with rheumatoid arthritis (RA) and 113 pts with non-inflammatory musculoskeletal symptoms (NIMS) in two control groups. Clinical diagnosis was the gold standard.

Late appearance and exacerbation of primary Raynaud's phenomenon attacks can predict future development of connective tissue disease: a retrospective chart review of 3,035 patients.

To assess the prognostic value of the age at onset of Raynaud's (RP) and of a history of exacerbation of RP attacks for the development of connective tissue disease (CTD) in patients initially found to have primary Raynaud's. 3,035 patients with primary RP (2,702 women and 333 men) were followed for an average of 4.8 years (range from 1 to 10 years).

Scleroderma pattern of nailfold capillary changes as predictive value for the development of a connective tissue disease: a follow-up study of 3,029 patients with primary Raynaud's phenomenon.

To assess the prognostic value of scleroderma pattern of nailfold capillary changes for the development of connective tissue diseases (CTD) in subjects with primary Raynaud's phenomenon (RP). The study included 3,029 consecutive patients with primary RP who had been followed at 6-month intervals during the mean of 4.8 years.
