Aseptic spondylodiskitis in rheumatic diseases.

Aseptic diskitis is relatively common. Several rheumatic diseases involving the spine may have this complication. As this condition mimic infectious diskitis, it is important to recognize it. Clinically, it is characterised by vertebral pain of an inflammatory nature, occasionally accompanied by fever and an increase in the erythrocyte sedimentation rate. Radiologically, the decrease in the articular space and the irregularity of the vertebral plates are of particular importance. Although uncommon, it is necessary to bear in mind this possibility when the etiological search for a possible infectious diskitis proves fruitless. A MEDLINE (1986-2000) and PUBMED (1966-2000) search of relevant articles was performed. Descriptors used were aseptic diskitis, spondylodiskitis, pseudodiskitis and pseudoarthrosis.

Prevalence and associated factors of anterior atlantoaxial luxation in a nation-wide sample of rheumatoid arthritis patients.

OBJECTIVE: To estimate the prevalence of anterior atlantoaxial subluxation (AAS) in patients with rheumatoid arthritis (RA), and to analyse its association with disease markers. METHODS: Cross-sectional analysis of a cohort of RA patients randomly selected from the clinical registries of 34 centres. AAS, defined as an atlantoaxial displacement in cervical spine X-rays greater than 3 mm on flexion films, was actively searched for. Bivariate and multivariate analysis was performed to examine its association with clinical, functional, and treatment variables. RESULTS: AAS was found in 88 out of 736 patients with available cervical radiographs, (prevalence and 95% confidence interval [CI]: 12% [9.7-14.2]). The presence of AAS was highly associated with a Larsen score (0-150) over 50 (OR and 95% CI: 5.31 [2.68-10.55]), RA duration of more than 10 years (4.48 [2.70-7.44]), disease onset before age 50 (4.15 [2.42-7.12]), eye involvement (3.93 [1.63-9.46]), and previous RA related surgery (3.90 [2.46-6.19]). No association was found with rheumatoid factor. Multivariate analysis showed that a disease onset before the age of 50, the number of previous DMARD, and, above all, a Larsen score greater than 50 were important independent factors associated with AAS. There is a 33% increased risk for AAS every 10 units up in the Larsen score. CONCLUSION: AAS is frequent in RA patients, particularly in those with markers of erosive disease.

Pseudotumoral articular amyloidosis.

We present a 71-year-old man with primary amyloidosis characterized by several outstanding clinical features, namely hip involvement of a pseudotumoral appearance, periarticular osteolytic lesions and a pathological fracture. Kappa light chains in the synovial fluid were observed. The patient survived for 90 months without developing plasma cell dyscrasia, and with preservation of vital functions despite parenchymal involvement of multiple organs.
