Septic arthritis of the posterior lumbar joints is extremely rare. The clinical picture of this unusual site of infection can easily lead to confusion with spondylodiscitis which is more common. We report a case of a 50-year-old woman with Staphylococcus aureus septic arthritis of the left L5-S1 lumbar facet joint. CT scan was helpful to establish the diagnosis and to guide the percutaneous needle biopsy.

We present one case of bursa formation secondary to a scapular osteochondroma. This rare condition can simulate, clinically and radiologically, a sarcomatous transformation. CT scan is helpful to demonstrate the scapular osteochondroma and the adjacent bursa.
Prospective study of 280 diabetic adults and 100 control show an association of limited joint mobility (LJM) with Dupuytren's contracture (DC) in 37 diabetic and no one of control case. In 80 diabetic with LJM, DC is found in 46.25 p. cent against 21 p. cent in 200 diabetic without LJM (p less than 0.00003). LJM and DC are significantly related to diabetic retinopathy and neuropathy. Their coexistence in diabetic patients, reported by other authors may be related to diffuse alteration of diabetic connective tissue.

A multicenter study of Behçet's disease in France confirms the male predominance (62 p. cent), the mean age of onset in the 4th decade, the frequent muco-cutaneous, ocular, articular manifestations (94 p. cent), the skin hypersensitivity (68 p. cent). The forms with arthralgia predominate; the knees are especially affected; arthritis has a favorable course; the para-articular forms are infrequent and in 4 cases, are associated with ankylosing spondylarthritis. HLA B5 is found in 47 p. cent of the cases. HLA-B12 in 22 p. cent. HLA-B5 is associated with eye involvement in 62 p. cent of the cases, HLA-B12 is associated with skin involvement in 67 p. cent of the cases. The effectiveness of colchicine and, at a lesser degree, of steroids, is confirmed.

The authors, in a series of 65 cases of Behçet's disease, notice 53% of rheumatological manifestations which are third in line after aphthosis and ocular disease. In order of decreasing frequency, it concerns arthritis (mono, oligo or poly-arthritis), arthralgias with an almost identical frequency, sacroiliitis, extraarticular involvement. These rheumatological manifestations are readily associated with necrotic pseudo-folliculitis and cutaneous aphthosis.

A case of pharyngeal stenosis in Behcet's disease is reported. A parallelism is done with other systemic disorders such as lupus erythematosus and Wegener's disease. Vasculitis and localised myositis are incriminated in the mecanism of the pharyngeal stenosis.

In a patient with disk herniation it is often difficult to establish that the disk is free in the spinal canal. A retrospective medical record study comparing 65 cases of free herniated disk (FHD) confirmed upon surgery and 65 cases of disk protrusion (DP) demonstrated that FHD was more common in young male blue collar workers, especially those who worked in the sitting position. No clinical findings were diagnostic of FHD although the straight-leg raising test was positive at smaller angles than in disk protrusion. In this study, sensitivity and specificity of CT scan for the diagnosis of FHD were 75% and 80%, respectively. CT scan findings suggestive of FHD included a free disk fragment, found in 22.5% of cases, and an acute connecting angle. Saccoradiculography was more sensitive but less specific than CT scan in this study. In FDH, migration was common and ragged hernia contours were seen on the saccoradiculography images.
