Benign pancreatic schwannoma
No full textPancreatic schwannoma is a relatively rare tumor originating from the lining cells of the nerve sheath. We report on a benign pancreatic schwannoma located in the pancreatic head and not associated with Recklinghausen’s disease. Based on the results of preoperative investigations and the intraoperative findings, simple resection of the mass was performed. The histology of the resected specimen showed a prevalence of Antoni B-type areas. Endoscopic ultrasonography proved very accurate in the evaluation of the anatomical relationships of the mass
Echolaparoscopic-guided alcohol injection of liver metastases
No full textUltrasound-guided percutaneous alcohol injection of liver metastases or hepatocellular carcinoma represents a well-established alternative to surgery when surgical resection is contraindicated. The aim of this report is to describe the technique of echolaparoscopic-guided alcohol injection of liver metastases in a patient undergoing palliative treatment for adenocarcinoma of the cardia. This procedure provides a more accurate staging of the disease and a safe approach to liver metastases with difficult anatomical location in patients unsuitable for surgical resection
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
Studio sul IVGTT in soggetti superobesi.
No full textIVGTT was performed in 16 extra-obese patients in order to evaluate the validity of the test in the functional biochemical study of massive obesity. Various glucose doses were used in order to identify the amount providing a constant glycaemic trend and therefore a reliable KG
