Lumbosacral pain: chordoma--a diagnosis not to forget.

Chordomas are rare tumours (1-4%) whose origin is remnants of the embryonic primitive foetal notochord. Estimated incidence is 0.51 cases per million. They develop at the neuroaxis ends and on vertebral bodies. Clinical manifestations can differ according to different localizations and to insidious and slow evolution. Our case is an illustration of diagnosis and treatment difficulties. Chordomas remain a diagnosis to be reminded.

Etanercept compared to intraarticular corticosteroid injection in rheumatoid arthritis: double-blind, randomized pilot study.

OBJECTIVE: To compare etanercept (anti-tumor necrosis factor-α) with intraarticular (IA) corticosteroid injections to treat rheumatoid arthritis (RA). METHODS: Patients with RA who had persistent monoarthritis received etanercept or IA corticosteroid injections. Efficacy was compared at Weeks 4 and 24. RESULTS: Thirty-four patients were included (8 dropped out). Mean age was 58.8 years. No difference between groups was found at Weeks 4 or 24, but both groups showed significant improvement at Weeks 4 and 24 compared to baseline. CONCLUSION: Etanercept and IA steroid injections resulted in significant improvement at Week 4 that persisted to Week 24. There was no significant difference in outcome between the groups.

Injection of intra-articular sodium hyaluronidate (Sinovial) into the carpometacarpal joint of the thumb (CMC1) in osteoarthritis. A prospective evaluation of efficacy.

OBJECTIVE: To compare the efficacy on pain relief and function of one, two or three injections of intra-articular hyaluronic acid in symptomatic osteoarthritis (OA) of the carpometacarpal joint of the thumb (CMCJ). METHODS: Among subjects with symptomatic OA of the CMCJ of the thumb referred to the Rheumatology Department of Nice, patients free of any joint injection in last 6months with pain visual analogue score (VAS) >40 and with Kellgren and Lawrence score between 2 and 4 were included. Each subject was randomly allocated to receive, at weekly intervals, 1 (group 1) or 2 (group 2) or 3 injections (group 3) of 1ml Sodium Hyaluronidate (Sinovial). Injections were given under imaging control. Sociodemographic characteristics, VAS and functionality (Dreiser Functional Index) were assessed at baseline, at one month and at three months. An intention to treat analysis was performed. RESULTS: Forty two subjects were enrolled in the study. Their mean age was 64.8 (8.0) years, and 90.5% were women. Baseline pain VAS, and mean Dreiser functional index were respectively 57.7 (17.1) and 12.5 (5.8). A repeated measure analysis of variance (ANOVA) model was used to compare the time-course profile of the three treatment groups for VAS and Dreiser index. Due to statistically significant groups-time interaction the analyses were conducted at each evaluation time. No difference was found for VAS at 1 month (p=0.075) and 3 months (p=0.382). Intra group differences between baseline and three months was significant in groups 2 and 3 (p=0.012 and p=0.002). CONCLUSION: No significant differences were found between each group over the study period for pain relief and function. But the intra groups analysis results show that intra-articular sodium hyaluronidate injections into the carpometacarpal joint of the thumb in osteoarthritis can be efficacious on pain and fuctionality. What is now needed is a controlled placebo randomised study with larger samples and longer term follow up of the achieved effects.

New-onset psoriatic palmoplantaris pustulosis following infliximab therapy: a class effect?

Reports of induction or exacerbation of psoriatic palmoplantaris pustulosis (PPPP) after anti-tumor necrosis factor-alpha (TNF-alpha) treatment are few. We describe 2 new cases of PPPP induced by infliximab. In 1999, a total of 442 patients in our department received anti-TNF-alpha treatment for a variety of chronic rheumatic conditions and were regularly followed. Medical records for 166 given infliximab were retrospectively reviewed for disease [rheumatoid arthritis (RA), spondylarthropathies (SpA) including psoriatic arthritis], disease duration, clinical characteristics, skin side-effects, and use of other potentially relevant medications. PPPP was observed in 2 patients treated with infliximab for symmetrical rheumatoid factor-positive RA; the patients had no personal or family history of psoriasis. In both cases, pustulosis appeared after several months of infliximab administration. There was no clinical, biological, or radiological evidence to support a diagnosis of psoriatic SpA. Both patients fulfilled ACR criteria for RA, and there was no reason to suspect previously unidentified psoriasis. Comorbid RA and psoriasis are unusual, and our patients exhibited a clear link between anti-TNF-alpha administration and cutaneous lesions, suggesting a direct effect in both cases. The 28 published cases of PPPP induced by anti-TNF-alpha treatment report lesions that tend towards pustulosis and palmoplantar localization. The mechanisms involved remain elusive. Disappearance of lesions in our second patient when switched to a soluble receptor suggests a molecule-specific side effect, while the literature describing variable reaction to switching anti-TNF agents, and/or their discontinuation and reintroduction, indicates otherwise. Given the rarity of this side effect, its elucidation will require systematic study.

Rheumatoid arthritis and spondyloarthropathies: geographical variations in prevalence in France.

OBJECTIVE: To determine geographical variation in the prevalence of rheumatoid arthritis (RA) and spondyloarthropathies (SpA) in France. METHODS: The survey sample was drawn from 7 areas of France. Households were randomly selected using the national telephone directory, and an individual within each household was randomly chosen by the next-birthday method. All cases of suspected RA and SpA were confirmed by the patient's rheumatologist or by clinical examination. Standardized estimates of prevalence were compared between regions and groups of regions. RESULTS: In total 15,219 anonymous telephone numbers were selected. An average response rate of 64% led to a total of 9395 respondents included in the study. The highest regional rates of RA were observed in the south (range 0.59-0.66%), and the lowest in the north (range 0.14-0.24%), with a national rate of 0.31% (95% CI 0.18-0.48%). Regional heterogeneity was observed for SpA, with the highest rates in Bretagne (0.47%) and the Sud-Est (0.53%) and a national rate of 0.30% (95% CI 0.17-0.46%). CONCLUSION: This study is the largest of its kind conducted in France. It shows inter-regional variations, mainly in RA, with a higher prevalence in the south of the country. The many potential reasons for the heterogeneity observed, including genetic and environmental factors, warrant further research.
