[The hemophilic femoropatellar joint].

The knee is the joint most frequently involved in haemophilia. Femoro-tibial damage in chronic arthropathies has been perfectly described. By contrast, lesions of the patella (with the exception of "squaring") have been reported in only a few scanty publications.

[Our experince with antiglobulin consumption (Dixon test) in the study of antibodies bound to platelets].

We measured the quantity of IgG bound to platelets (IgGP) by the antiglobulin consumption test (Dixon technic). In controls, the IgG level did not exceed 10 X 10(-15) g for one platelet. The amount of IgGP was often incraeased (more than 10 X 10(-l5) g) in some autoimmune diseases as lupus erythematosus, chronic lymphocytic leukemia and chronic active hepatitis.

[Serum beta-2-microglobulin in multiple myeloma. Practical value].

The concentration of serum, beta-2-microglobulin (S beta 2m) and the ratio measured S 2m/theoretical S beta 2m M/TH were evaluated in 69 patients with multiple myeloma (MM) and compared with healthy subjects and with patients with a benign monoclonal gammapathy. The concentration of S beta 2m and the ratio S beta 2m M/TH are higher in multiple myeloma than in controls and are strongly correlated with the plasma cell mass On the other hand, no difference was noted concerning the S beta 2m and the ration S beta 2m M/TH between benign monoclonal gammopathy and multiple myeloma at stage I of Durie and Salmon. Under chemotherapy, the variations in concentrations of S beta 2m and of the ratio S beta 2m M/TH are strongly correlated with those of the tumour mass.

[Therapeutic failures in early stages of Hodgkin's disease : causes and prevention (author's transl)].

A retrospective study of 65 patients with Hodgkin's disease (clinical stage I: 11 cases; stage II: 54 cases) included an analysis of the causes of therapy failure. Twenty-five of the 65 patients had been treated by regional irradiation (thoracic mantle or inverted Y field) restricted to only one side of the diaphragm; 27 patients had received the same irradiation followed by chemotherapy (MOPP). The subjects were irradiated on both sides of the diaphragm; 3 of these had received the same radiotherapy followed by chemotherapy (MOPP).

[Deaf-mutism, lymphedema of the lower limbs and hematological abnormalities (acute leukemia, cytopenia) with autosomal dominant transmission].

Report of a syndrome constituted from sensorineural deaf mutism, lymphoedema of lower limbs with early onset and haematological anomalies (aucte myeloblastic leukaemia, cytopenia) in four individuals (three boys and two girls from two generations). This observation suggest autosomal dominant transmission, however recessive transmission cannot be formelly excluded.

[Multiple myeloma of bones. Retrospective study of prognostic factors based on a series of 243 patients].

The authors have made a retrospective study of 243 cases of multiple myelomas, most of them treated with alkylating agents. The average age at the time of diagnosis was 65 years (+ 10). The ratio of the sexes was 1 : 1.
