Retrospective analysis of the association of nodular goiter with primary and secondary hyperparathyroidism.

Background: The association of hyperparathyroidism (HPT) with thyroid disease has long been known, but the mechanisms underlying such an association have not yet been clarified.

Objective: To elucidate the main factors determining this combination of endocrine diseases, in a retrospective multicenter study.

Methods: We retrospectively reviewed all patients referred for parathyroid scintigraphy in the period 1990-1999.

Immunohistochemical reactivity of anti-melanoma monoclonal antibody 225.28S in human breast cancer biopsies.

The high molecular weight melanoma-associated antigen, defined by murine monoclonal antibody (IgG1) 225.28S is largely expressed by melanoma cells and weakly expressed by other human tumors originating from neural crest. In this study, we analyzed the immunohistochemical reactivity of MoAb 225.

[Transcutaneous radiotherapy after thyroidectomy for differentiated thyroid carcinoma].

Purpose: To compare the results, in terms of 10-year actuarial survival, between I-131-therapy and I-131-therapy + external beam radiotherapy (RT) in patients operated on for differentiated thyroid carcinoma.

Patients And Methods: Over a period of 13 years (1982-1995) 408 patients underwent thyroidectomy with or without linphoadenectomy for pT0/T4 Nx or pN0, pN1a, pN1b thyroid carcinoma. In all cases, thyroidectomy was radical.
