Proposed classification criteria of psoriatic arthritis. A preliminary study in 260 patients.

Unlabelled: Psoriatic arthritis probably owes to its radioclinical presentation its position as the most controversial and poorly understood of all major chronic inflammatory joint diseases. Differentiating psoriatic arthritis from ankylosing spondylitis and rheumatoid arthritis remains difficult.

Objective: To conduct a statistical analysis aimed at identifying clinical, radiological, and laboratory criteria for classifying psoriatic arthritis.

Adhesive capsulitis of the shoulder: therapeutic contribution of subacromial bursography.

Objective: To demonstrate the therapeutic value of subacromial bursography (with a steroid injection) in adhesive capsulitis of the shoulder inadequately improved by arthrographic glenohumeral distension with steroid injection.

Method: Twenty cases of adhesive capsulitis documented by glenohumeral arthrography were studied prospectively. A steroid was injected during distension arthrography, which was followed by physical therapy.

A case of primary hypertrophic osteoarthropathy without skin involvement (Currarino's disease).

Hypertrophic osteoarthropathy is characterized by digital clubbing, arthropathy and periostosis of long tubular bones. Currarino's disease is an extremely rare variant of primary hypertrophic osteoarthropathy in which there is delayed closure of the fontanelles and an absence of skin involvement. Most reported cases have been in blacks.

Iliopsoas bursopathies. A review of twelve cases.

Synovial cysts are far less common at the hip than at the knee and usually occur in patients whose hip cavity communicates with the iliopsoas bursa. We report 12 cases of enlargement of the iliopsoas bursa, nine men and three women, with a mean age of 48 years. The six patients with septic bursitis had severe symptoms similar to those seen in septic arthritis of the hip.

Frozen shoulder: a new delayed complication of protease inhibitor therapy?

We report three cases of frozen shoulder (including one with bilateral involvement) in human immunodeficiency virus (HIV)-positive patients under triple antiretroviral therapy. In each case, the diagnosis was confirmed by arthrography, and the classic causes of frozen shoulder were ruled out. We suggest that protease inhibitor therapy may have contributed to the development of frozen shoulder in these patients.

Inflammatory rheumatism and nasal polyposis.

We report five cases of seronegative inflammatory rheumatism associated with nasal polyposis. The patients were four women and one man, mean age 49.5 years (range 42-59 yrs.

Transient vertebral osteosclerosis due to osteoporosis.

Diffuse uniform vertebral osteosclerosis in vertebra affected by osteoporotic crush fracture, without osteonecrosis is reported. Multiple fissure-fractures were seen upon magnetic resonance imaging.
