Estimation of hepatic volume by SPECT during liver regeneration: an experimental study in an animal model.

To calculate hepatic volume in the dog by single photon emission computerized tomography (SPECT), we determined the limits of the organ by choosing an isocontour on each section. This choice entailed prior calculation of an overestimated pseudovolume. The accuracy of the measurement in the animal then approached that of measurements in vitro. We used the method to monitor hepatic regeneration in the dog after 65% hepatectomy and detected oedema and postoperative trauma, and over a longer timespan, stagnation of regeneration and a secondary drop in hepatic volume.

[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. Beta 2m is not very useful for the differential diagnosis between benign monoclonal gammapathy and multiple myeloma. Beta 2m is very useful in the prognosis of MM, permitting one to assess accurately the tumour mass and the response to treatment, particularly in cases of deficiency of the usual markers.

[Comparison of the variations in the levels of beta2-microglobulin and carcino-embryonic antigen in the breast cancer and malignant melanoma (author's transl)].

A variety of markers have been used in the surveillance of carcinoma of the breast and malignant melanoma, including carcino-embryonic antigen (CEA) beta2-microglobulin (beta2m) and prolactin. The dual purpose of the surveillance was the detection of early recurrence or metastasis and the monitoring of the treatment. In cancer of the breast 92% of patients having bone metastases have elevated levels of CEA or beta2m. In malignant melanoma 2/3 of the patients in relapse have elevated beta2m levels.

[The salivary glands during rheumatoid arthritis].

Salivary gland lesions were studied in 65 non-selected, confirmed rheumatoid polyarthritis patients. The investigations included a careful clinical study, the Schirmer test, sialography, sequential scintigraphy with Technetium 99, and a histological study of the sublingual glands. Tests were also made for salivary gland anti-epithelium antibodies. The frequency of sialography and scintigraphy anomalies is emphasized. In different degrees, two of of three patients presented anatomical or functional anomalies of the salivary glands. These disturbances were not related to the duration, the functional severity, or the treatment of the disease or to the presence of anti-salivary gland antibodies. On the other hand, there was a clear relation with both the presence of anti-nuclear antibodies and an increase in the serum gammaglobulin levels. The limits of the Gougerot syndrome are discussed and it is proposed that there is a need for a second nosological class grouping the minor scintigraphic and sialographic anomalies related to rheumatoid arthritis that has been suggested by several authors.
