[Systemic lupus erythematosus, polymyositis and toxoplasma antibodies].

High toxoplasma antibody titers have been reported in polymyositis and other connectivitis with myositis. The authors describe a case of systemic lupus erythematosus with polymyositis and high titers of IgG toxoplasma antibodies. Studies of muscle biopsy specimens by immunofluorescence and inoculation of mice with muscle extracts failed to demonstrate the presence of Toxoplasma gondii. The nature of the toxoplasmic agression is discussed. It may be that reactivation of a previous infection due to the rupture of cysts was promoted by the immunologic disorders and complement deficiency related to systemic lupus erythematosus.

[Metacarpophalangeal calcifications in diffuse chondrocalcinosis. Radiologic study of ten cases (author's transl)].

The authors report ten cases of metacarpophalangeal calcifications in chondrocalcinosis. These calcifications are associated with a calcification of the triangular ligament of the wrist in the all cases. Cartilaginous calcifications of the wrist are found in 9 cases. Metacarpophalangeal calcifications concern mostly the third (9 cases) and the second (6 cases) metacarpophalangeal joint. They are present frequently on radial side (29 joints) rarely on cubital side (5 joints) with a calcification on radial and cubital side in 4 joints and a calcification on cubital side only in one joint. Calcic deposit concern almost the synovial and capsule, it is rarely cartilaginous one. The authors discuss the possibility of calcic deposit of the glenoidal fibrocartilage of the metacarpophalangeal joint.

[Auditory and vestibular lesions in Behcet's disease].

Auditory and vestibular function tests were conducted in 16 patients with Behcet's disease. Vestibular lesions included spontaneous nystagmus in 5 cases, and a bilateral vestibular syndrome after provoked tests in 13 cases (7 of the deficiency type and 6 irritative in nature). Findings after auditory tests were bilateral symmetric deafness in 2 cases; one of the perception type and the other showing mixed features. Various etiopathogenic theories are discussed. The possibility of a bilateral central lesion of the VIIIth nerve was also considered, 8 patients in the series having cerebral manifestations, particularly as the results of visual fixation tests in these cases were in favor of this hypothesis.

[CRST syndrome (Thibierge-Weissenbach's syndrome) and intra-articular calcification: a case report (author's transl)].

A case of Thibierge-Weissenbach's syndrome is reported in a woman with very advanced generalized scleroderma, telangiectases, subcutaneous calcinosis, and a Raynaud's syndrome. Atypical radiological appearances were noted: intra-articular calcinosis of the radioulnar, metacarpo-phalangeal, and metatarso-phalangeal joints. The published literature is reviewed.
