title: [The new clinical picture of primary hyperparathyroidism. Diagnostic circumstances and current symptomatic characteristics. Results of a multicenter study].
abstract: Primary hyperparathyroidism (PHP) is particularly interesting at this time because of the modifications of its traditional symptoms, which have renewed the conditions of its diagnosis. This is the result of a better knowledge and consequently an increased frequency of the simple forms, mild or clearly atypical, usually expressing the initial stages of the disease which are now better detected. The relative part of the classical manifestations of the disease is therefore reduced as well. In order to verify this fact, the authors have initiated a retrospective study of 535 recent cases of PHP, over 12 years, comparing them with 322 older cases, examined and operated upon between 1954 and 1976 by P.L. Chigot. Analysis of the differences that were noted, was the subject of a statistical evaluation. The first result of this investigation is that PHP remains a disease affecting predominantly women, especially between the ages of 40 and 60 years, and beyond that age to a lesser degree. In comparing the data obtained from analyzing the circumstances of discovery of the disease and its symptoms, the most striking modification consisted in a real drop in the frequency of bony lesions. These modifications are much more rare, only exceptionally presenting their classical characteristic X-ray appearance and they only represent a factor of contingency in the clinical picture of PHP. This is probably the result of a much earlier discovery of the disease. The incidence of renal insufficiency is also remarkably low, probably for the same reason. In return, asthenia and urinary lithiasis are now the major symptoms of PHP.(ABSTRACT TRUNCATED AT 250 WORDS)
