[Disk calcinosis].

Intervertebral disc calcification in children is a rare, primary and benign disease which often disappears after a single painful crisis, especially in cervical involvement. In adults, thoracic and lumbar discs are mainly involved; calcification is less expressive and is often detected during a casual radiograph. Intervertebral disc calcification is primary or secondary to chondrocalcinosis, apatite deposition disease, ochronosis and hemodialysis spondylarthropathy. Except CPPD deposits in chondrocalcinosis, calcium complex accounting for most discal calcinosis is hydroxy-apatite. Iatrogenic intervertebral disc calcification was recently described in patients treated with a discal injection of a long-acting corticosteroid.

[Association of rheumatoid arthritis and Kaposi disease. Apropos of a case arising after intraarticular corticotherapy].

A 66 year old Corsican HLA A2 and DR5-positive male with moderately active seropositive destructive rheumatoid arthritis developed Kaposi's sarcoma after intraarticular administration of corticosteroids. He had no history of oral corticosteroid therapy, organ transplantation, AIDS, or cancer. Chlorambucil proved ineffective but the outcome was spontaneously favorable following discontinuation of oral corticosteroid therapy initiated after the development of the skin lesions. Six previous reports of concomitant rheumatoid arthritis and Kaposi's sarcoma were found. All six cases occurred following systemic corticosteroid therapy. The high incidence of rheumatoid arthritis and the small number of patients with rheumatoid arthritis and Kaposi's sarcoma suggest that concomitant occurrence of the two conditions may be fortuitous. However, the responsibility of corticosteroid therapy, which preceded development of Kaposi's sarcoma in every case, cannot be ruled out.

[Lumbar inter-apophyseal arthrosis and bone mineral content: prospective study versus controls with dual photonic absorptiometry and tomodensitometry].

Dual photon absorptiometry (DPA) is a non invasive and repeatable technique to measure vertebral bone mineral content (BMC). This method can be altered, in frontal incidence, by superposition of abnormal calcifications as calcified aorta or interapophyseal arthrosis. The authors studied nineteen females with lumbar apophyseal arthrosis compared with twenty one controls matched by age. Bone densitometry was performed by Am-Ba DPA and monoenergetic computerised tomodensitometry (CT) from L2 to L4. Arthrosis was studied by standard X ray radiographs and CT. Our results showed that inter-apophyseal arthrosis does increase BMC determined by DPA, especially when expressed as linear BMC (g/cm). The body mass index [weight (kg)/size (m2)] also increased these measures by DPA. CT results were, at the opposite, not influenced by osteo-arthrosis nor body mass index. Detailed analysis of DPA pictures allowed to recognize most of patients with osteo-arthrosis and to correct their results by using adjacent vertebral measures (L1) or abandoning pictures of unusual aspect. The authors mentionned necessity to match populations for age and body mass index and to include L1 in routine vertebral bone mineral content determination. By this way they supposed that osteo-arthrosis may not alter lumbar BMC measured with DPA technique.

[Infectious spondylodiscitis. Analysis of a series of 105 cases].

Among 105 cases of infectious spondylitis diagnosed and treated from 1971 through 1990, 23 were due to tuberculosis (TS) and 82 to other causes (NTS). The annual number of cases of NTS rose over the study period, partly because of an increase in iatrogenic spondylitis, whereas the number of TS cases fell. In both groups, mean age of patients was higher than in earlier studies. The leading causative agents in NTS were staphylococci, followed by streptococci, then Escherichia coli. Diagnosis of spondylitis was dependent on the imaging techniques used; among available methods, the most reliable was magnetic resonance imaging which improved diagnostic performance by detecting early, specific changes. Except in patients with positive blood cultures and in TS patients with Koch bacilli recovered from other visceral foci, bacteriologic diagnosis rested on studies of samples taken from the spinal infection site. Half the subjects underwent discovertebral needle biopsy, with a success rate of 47.5%, a figure comparable with those reported in other studies. In 30% of patients, bacteriologic documentation of the infection was not obtained and diagnosis rested on a set of clinical, biological, and radiological criteria.
