Primary hyperparathyroidism: can ultrasonography be the only preoperative diagnostic procedure?
Preoperative detection and localisation of enlarged parathyroid glands can be based on US, an inexpensive and widely available method, limiting the use of scintigraphy to those cases with negative and/or doubtful findings on US.
The data indicate that HGF is a potent growth factor for LECs and may contribute to the development of PCO and suggest that the signaling pathways involved in HGF-stimulated proliferation may constitute potential therapeutic targets in the treatment of PCO.
