Surgical aspects of thyroid nodules previously treated by ethanol injection
No full textAbstract
Some concern has been expressed about surgical operations in thyroid nodules previously treated by ethanol injection: the reasons are mainly represented both by the possibility of more surgical risks due to the adhesions caused by ethanol and the difficulty of interpreting the histological pattern when a cancer is suspected. During the last 8 years 219 patients underwent ethanol injection: among these 6 were subsequently submitted to surgical operation. Total thyroidectomy was performed in 5 cases and isthmusectomy in one case: No vocal cord palsy was registered in these patients.. They were all normocalcemic after surgery. Histology showed no significant fibrosis in the ethanol treated nodules but only macrofollicles and this did not affect the histological examination in presence of suspected malignan
A case of Cushing’s syndrome due to adrenocortical carcinoma with recurrence 19 months after laparoscopic adrenalectomy.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
