Intracholecystic Papillary-tubular Neoplasm (ICPN) of the Gallbladder: A Case Report Focusing on an Unexpected Pathological Finding
No full textBackground: Intracholecystic papillary neoplasms (ICPNs) represent a rare benign entity characterized by intraluminal polypoid lesions in the gallbladder. The incidence of ICPNs ranges from 0.4% to 0.61% in all gallbladder specimens. Case presentation: In this report, we present a case of a young Caucasian woman who underwent elective laparoscopic cholecystectomy due to gallbladder polyps. The histological examination revealed the presence of an intracholecystic papillary neoplasm (ICPN) with a tubulopapillary growth pattern, exhibiting gastric morphology and displaying both low and high-grade dysplasia. A thorough review of the existing literature was conducted, with a specific focus on the histological features. Conclusion: A comprehensive understanding of neoplastic polyps of the gallbladder is still limited. Pathological examination of these lesions is crucial for identifying key features that can influence patient outcomes and survival
Radiation-induced angiosarcoma of the breast: an uncommon polymorphic disorder
No full textBreast conservative surgery combined with whole-breast radiotherapy has become the gold standard for the treatment of breast cancer, leading to the risk of subsequent occurrence of a secondary breast angiosarcoma in the irradiated area. We describe a case series
Hickam versus Ockham: atopic dermatitis and bullous pemphigoid or pemphigoid nodularis? Dupilumab solves the problem
No full textFrom a diagnostic point of view, the case presented raises a dilemma, in fact, it is not possible to state with certainty whether the patient described suffered from pemphigoid nodularis or from concomitance of atopic dermatitis prurigo nodularis-like and bullous pemphigoid. In spite of this diagnostic dilemma, our findings support the use of dupilumab in atopic dermatitis prurigo nodularis-like, bullous pemphigoid and pemphigoid nodularis, especially in treating pruritus
Intraosseous glomus tumor of the ankle: A case report and review of the literature
No full textGlomus tumors are benign vascular lesions composed of uniform round to oval cells, resembling normal glomus bodies that can be classified as paragangliar tissue derived from neural crest, which participates in thermal regulation. They usually occur in the peripheral soft tissues, most frequently in the digits, where the glomus bodies are normally present. However, they may arise in diverse locations such as bone, stomach, intestines, or neural tissue, where the glomus bodies are thought to be sparse or even absent. Glomus tumors can be solitary or multiple. The solitary acquired form is more common. Multiple glomus tumors are rare and are inherited as an autosomal dominant trait. The onset usually is in adolescence with a male predominance; between 30 and 60 years, the predominance is female. The tumor consists of glomus cells, vascular structures, and smooth muscle tissue in varying proportions. Glomus tumors have been divided into three groups according to the relative proportions of these components: glomus tumor proper, glomangioma, and glomangiomyoma. In case of histologic uncertainty, immunohistochemical features may be helpful for differential diagnosis, including hemangiopericytoma, leiomyosarcoma with epithelioid change, rhabdomyosarcoma, Ewing sarcoma, and nodular hidradenoma. Glomangiomas, which usually are encountered in patients with multiple lesions, constitute approximately one fifth of the cases and are predominately on the hand and forearm. Pain radiating proximally or distally from the lesion is the most common complaint. The classic diagnostic triad consists of local pain, tenderness to pressure, and cold hypersensitivity. The pain is elicited by changes in temperature, emotional excitement, and even minimal touch on the lesion. The pain is partially mitigated by nonsteroidal anti-inflammatory medications
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
