[Endodermal sinus tumor. Histological changes induced by chemotherapy].
No full textThe case of a child affected at birth sacrococcygeal teratoma is reported. Twenty-eight months following surgical resection, the tumor relapsed locally and liver metastases occurred. A biopsy of the sacrococcygeal mass was performed and histologic examination proved it to be an endodermal sinus (yolk sac) tumor. Chemotherapy consisting of etoposide and high-dose carboplatin was started. When a second operation was performed the mass had disappeared and the macroscopically involved areas of liver were removed. Histologic examination demonstrated that the complete necrosis of the tumor was partially replaced by a fibrous scar tissue. The child underwent adjuvant chemotherapy and now is in complete remission fourteen months after the last operation
Unique pineal gland metastasis of clear cell renal carcinoma: case report and review of the literature.
No full textThe metastatic involvement of the pineal gland is an extremely unusual event; it has a 4\% incidence in patients with disseminated neoplasias. Most metastatic pineal lesions are asymptomatic. Only in a small number of cases the symptoms produced by metastatic involvement of this organ precede those of the primary tumor or those of another metastatic site. To our knowledge the herein reported case is the first in which the pineal gland was apparently the unique metastatic site of a primitive kidney carcinoma and where the symptoms produced by metastasis in the pineal region were the first sign of the disease
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
