[Tomodensitometry in osteoarticular pathology. Preliminary results].

From the investigation of 180 patients, the preliminary results of tomo-densitometric study ("scanning") of the locomotor system are presented. The technique permits investigation in the transverse spatial plane, which is ignored in conventional radiology. We feel this to be a major advantage in osteo-articular disease, especially for the spine (measurement of the diameter of the canal, analysis of the posterior structures), the sacro-iliac joints, hip joints (easy-measurement of the angles of anteversion) and patello-femoral joints. The densitometric measurement is the second advantage. It allows the estimation of the degree of bony calcification of any bone in the body with great precision. The preliminary study already demonstrates the limitations of the technique (exploration of a single transverse plane, edge effect, and necessity for a new anatomy).

[Current status of conservative and surgical treatment of tuberculosis arthritis in adults (author's transl)].

The more efficient present day treatment with bactericidal anti-tuberculosis drugs combined with surgical procedures results in a much more rapid and longer lasting cure of tuberculous arthritis than previously. We assume actual periods of treatment between 2 and 4 months. It should be borne in mind that tuberculosis is a systemic disease and that the arthropathy only ranks second or third. Godd results are obtained if all concerned in the treatment of tuberculosis harmonize their approach to the treatment.

Radiological scoring methods in ankylosing spondylitis: reliability and sensitivity to change over one year.

Our aim was to compare reliability and sensitivity to change of different radiological scoring methods in ankylosing spondylitis (AS). Two trained observers scored 30 AS radiographs twice with an interval of 4 weeks. The same two observers scored 187 AS radiographs in pairs, at baseline and after one year followup, to measure change and agreement on change. The sacroiliac (SI) joints were scored in 5 grades by the New York method and the SASSS (Stoke Ankylosing Spondylitis Spine Score). Hips were graded 0-5 (according to Larsen). Cervical and lumbar spine were graded (0-4, Bath Ankylosing Spondylitis Radiological Index, BASRI), and scored in detail (0-72, SASSS). SASSS of the cervical and lumbar spine scored on the anterior sites of the vertebrae proved most reliable, with both intra and interobserver intraclass correlation coefficients (ICC) between 0.87 and 0.97. BASRI was only moderately reliable, with Cohen's kappa ranging between 0.50 and 0.82 for intra, and 0.38-0.64 for interobserver reliability. Similarly, SI joint scores (New York, SASSS) showed intraobserver kappa between 0.56 and 0.84, and interobserver reliability with kappa between 0.37 and 0.47. Larsen hip scores proved unreliable: moderate intraobserver kappa of 0.47-0.58 and low interobserver kappa of 0.29. After retraining, interobserver kappa did not improve (0.45 and 0.17). In retrospect, a one year period was too short to measure sensitivity to change. Observers agreed that no change occurred in up to 89% of cases. A measurable change of deterioration or improvement occurred rarely. We conclude that in AS, only the SASSS method for the spine and the BASRI reached good reliability. Other methods for spine, SI joints, and hips were moderately reliable at best. There was moderate to good agreement on no change between the observers. No method showed change over a period of one year in a considerable number of patients.

Radiographic diagnosis of sacroiliitis--are sacroiliac views really better?

OBJECTIVE: To determine whether detailed oblique radiographs of the sacroiliac (SI) joints provide significant diagnostic advantage to a single AP projection of the pelvis in establishing the presence and severity of sacroiliitis. METHODS: Radiographs (both AP pelvis and detailed oblique projections) of 445 right SI joints and 442 left SI joints were obtained from patients with an established diagnosis of a seronegative spondyloarthropathy, and interpreted for severity. Data for the right and left SI joints were analyzed, comparing interpretations of severity based on AP pelvis projections with oblique views. RESULTS: Analysis of these data showed an agreement rate between AP views and SI views of 89.7% for the right SI joint radiographs and 86.4% for the left SI joint. There was no instance in which a patient with "unequivocal abnormalities"of the SI joints on the AP pelvis was read as having "normal" SI views. Similarly, there were no cases in which "normal" SI joints on AP pelvis films were read as having unequivocal abnormalities on SI views. CONCLUSION: In this group of patients with seronegative spondyloarthropathies, there was very close agreement between severity score of sacroiliitis from AP pelvis radiographs and SI joint views. We conclude that in most circumstances, the AP pelvis film will yield the diagnosis of sacroiliitis without the additional radiation exposure and expense related to specific SI joint radiographs.

Efficacy of etanercept in the treatment of the entheseal pathology in resistant spondylarthropathy: a clinical and magnetic resonance imaging study.

OBJECTIVE: To determine the effect of tumor necrosis factor alpha (TNFalpha) blockade with etanercept on the clinical manifestations of resistant spondylarthropathy (SpA) and on axial and peripheral entheseal lesions using magnetic resonance imaging (MRI). METHODS: We performed a descriptive longitudinal study of 10 SpA patients, all of whom had active inflammatory back pain and peripheral involvement. Patients were treated with 25 mg subcutaneous etanercept twice weekly for 6 months. Clinical assessments included entheseal count, visual analog scale (VAS) scores for spinal pain during the day and night, VAS scores for entheseal pain, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. MRI scans of sacroiliac (SI) joints, the lumbar spine, and affected peripheral joints were performed using a 1.5T scanner employing T1-weighted, T2-weighted fat-suppressed (FS), and T1-weighted FS postgadolinium sequences at baseline and at 6 months. Enthesitis and associated osteitis were scored semiquantitatively in pre- and posttreatment scans. RESULTS: There was a statistically significant improvement in all clinical and functional parameters (P = 0.008 for VAS spinal pain score during the day and for VAS spinal pain score during the night, P = 0.008 for the BASFI, and P = 0.005 for the BASDAI) as well as in quality of life (P = 0.005 for the ASQoL) at 6 months. Nine patients had a total of 44 MRI-detectable entheseal lesions. These were seen in the SI joints in 6 patients (n = 15 lesions), in the lumbar or cervical spine in 9 patients (n = 22 lesions), and in peripheral joints in 5 patients (n = 7 lesions). Overall, 86% of MRI-detected entheseal lesions either regressed completely or improved. No new lesions developed. CONCLUSION: These findings suggest that TNFalpha blockade with etanercept is markedly effective in controlling the clinical manifestations of SpA that is resistant to disease-modifying antirheumatic drugs. This is associated with marked improvement of enthesitis and associated osteitis pathology as determined by MRI.
