[Intra- and extra-pelvic venous connections. Anatomical study].

Regarding to clinical diseases, the authors emphasize the important part of pelvic veins as collateral flows when iliac channels are occluded. They point out the three mains streams of this collateral network: the obturator veins, the gluteal veins, and the pudendal veins. Longitudinal anastomoses are connected each other by transversal veins such as Santorini plexus, and sacral veins; they allow venous supply from one side to the other when two levels or more are involved.

[Osteoporosis at high remodeling and parathyroid function. Histo-biological confrontations (author's transl)].

In order to evaluate the relationship between apparently idiopathic osteoporosis and parathyroid hormone secretion, plasma immunoreactive parathyroid hormone (iPTH) was measured in 57 untreated osteoporotic patients using a carboxyl-terminal specific antiserum, and sections of undecalcified iliac bone biopsies from these subjects, who had been previously doubly labelled with tetracycline, were quantitatively analysed. Twenty-one patients (36%) exhibited histological signs of a high remodeling similar to that which is present in primary hyperparathyroidism, but their osteoplastic appositional rate values were lower. Among these 21 cases 8 had an increase of their iPTH levels. These data and those of the literature indicate that in a few cases high remodeling osteoporosis may be associated with parathyroid hypersecretion, but do not bring out the evidence that the increased circulating iPTH is the cause of osteoporosis. The authors draw from their results some practical consequences for the treatment of high remodeling osteoporosis.
