[Evaluation of bone density in women after thyroid cancer surgery and treatment with suppressive doses of L-thyroxine].

The aim of this work was to evaluate the degree of bone resorption and incidence of osteoporosis in female postmenopausal patients with differentiated thyroid cancer treated with suppressive doses of thyroxine. During the regular follow-up of women with differentiated thyroid cancer, densitometry of lumbar spine (L2-L4) and femoral head were performed. urine concentration of deoxypyridinoline and calcium-phosphate metabolism were also evaluated.

[Comparison of efficacy of various methods of thyroglobulin measurements in differentiated thyroid cancer].

Monitoring patients with differentiated thyroid carcinoma (DTC) by thyroglobulin (Tg) measurements requires selecting optimal methods used for detection of this marker. An increase the thyroglobulin concentration in serum is a predictor of tumor recurrence. All serum thyroglobulin assays can be falsified by presence of Tg autoantibodies, which are present in approximately 20% of DTC patients.

[Usefulness of the Visidex II (Ames) strip test for monitoring insulin therapy at home].

Blood glucose was determined with o-toluidine and Visidex II (Ames) in 234 adult diabetics. The highest conformity of the results in both techniques was achieved in the range of blood glucose concentrations 70-110 mg%. The authors are convinced that Visidex II may be valuable in monitoring of normoglycaemia during intensive therapy with insulin, eg.

Terminal deoxynucleotidyl transferase in diagnosis of lymphomas.

TdT activities were determined on 29 specimens of mononuclear blood, bone marrow or lymph node cells from 18 patients with non Hodgkin's Lymphomas, 2 Hodgkin's patients and 3 patients with non neoplastic lymph nodes. The neoplastic cells were typed using tests detecting membrane markers (E, Em, SIg), and monoclonal antibodies (MoAb). In a group of 15 patients with Low Grade Malignant Lymphoma (L.
