    Renal papillary adenocarcinoma with unusual metastases; case report and review of literature

    No full text
    Objective: This study focuses on a case report on a patient with renal carcinoma who developed metastases at unusual sites. We also reviewed the literature, including the theories proposed by various authors on the possible etiology of these odd localizations. Case report: A 48-year-old patient underwent conservative surgery for renal carcinoma (papillary adenocarcinoma). Twenty-two months later, he developed mediastinal metastases and underwent immunotherapy; two years after that he had metastases to unusual sites such as the urethra and the prostate. The mechanisms responsible for metastases to these unusual sites are not entirely clear yet. We feel it is important to note the highly aggressive and multifocal nature of papillary adenocarcinoma, and the need to perform closer follow-up on these patients, particularly if nephron-sparing surgery has been performed

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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
