[Post-traumatic psoriatic rheumatism. Clinical and medico-legal aspects].

The possibility that injury may play a role in the development of some forms of chronic inflammatory rheumatic disease has been a subject of debate for many years. Such a role is accepted for some cases of rheumatoid arthritis, remains controversial for spondylarthropathies, and is poorly understood in psoriatic arthritis. Three cases of post-traumatic psoriatic arthritis are reported herein. The difficulty of establishing the causative role of the injury (despite precise criteria) is underlined, the pathophysiologic mechanism is discussed (deep Koebner phenomenon?), and possible legal consequences are reviewed.

Tietze's syndrome: a critical review.

A critical review of Tietze's syndrome and the relevant literature to date is presented. The disease has been characterized as a tender, non-suppurative swelling in the upper costosternal region. The etiology and pathology of the disease are still unknown. In the past decade new knowledge concerning rheumatic diseases affecting the anterior chest wall has modified our approach to this condition. Tietze's syndrome could be more a part of seronegative disease than has been previously recognized, even if the existence of this condition as an entity cannot be totally denied.

[Infections and immunosuppressive agents in rheumatology].

The authors review the problem of infection occurring in patients with chronic inflammatory rheumatism, e.g. rheumatoid arthritis, and lupus erythematosus, treated with cytolytic drugs for immunodepressive reasons. From their investigation, it seems that there is a high frequency of bacterial and mycotic and viral infections in these patients, but controlled investigations seem to show quite definitely that the frequency of these infections depends on the disease itself. The risk does not seem to be increased by cytolytic drugs. The only exception is herpes which appears in 10 to 20% of patients treated with immunosuppressive agents, as against 2% in a controll series. The other virus diseases did not have an abnormally high frequency. The conclusions are, of course, only of value for the types of treatment used in rheumatology.

[Chronotherapy of tenoxicam].

A study was carried out in order to investigate the chronotherapy (dosing time dependency) of an NSAID, the tenoxicam administered in ankylosing spondylitis, rheumatoid arthritis and osteoarthritis of the hip. These variations in efficacy exist as much for pain as for stiffness and maximum efficacy is obtained with administration at 8 am or 12 pm. Since the tolerance was good, we recommend midday as an optimal once-a-day dosing time.

Two familial cases of malignant Reiter's syndrome.

A Cambodian man and his son concomitantly developed malignant Reiter's syndrome soon after their arrival in France. In both cases generalized skin lesions of pustular psoriasis and systemic features were present. The son died after 2 years of unresponsive continuously progressive disease. The father received pulses of high dose immunosuppressants that worked rapidly and prevented a life threatening course. These 2 cases illustrate the pathophysiologic hypothesis of Reiter's syndrome, emphasizing the role of environmental triggering factors and the relationship between spondylarthropathies in B27 positive patients. Fatal cases of Reiter's syndrome are very rare in the review of the literature.
