No full textAnthropometric measures, medical history and risk of basal cell carcinoma in an Italian case-control study
No full textBackground/Aims: A few epidemiological studies investigated etiological factors for basal cell carcinoma (BCC) other than sunlight exposure and sunburns. Information on anthropometric measures and medical history is scant. Methods: We examined the issue in a case-control study including 528 patients with incident, histologically confirmed BCC and 512 controls hospitalized with acute conditions. Results: Odds ratios (OR) for the highest versus the lowest quartiles were 0.77 for weight, 0.99 for height, 0.87 for body mass index and 0.81 for body surface area. Corresponding estimates for trunk BCC were 0.42, 0.81, 0.50 and 0.47. Subjects with asthma (OR = 0.26) and diabetes mellitus (OR = 0.23) showed a decreased risk of trunk BCC but not face and neck BCC. Conclusion: The inverse relations between trunk, but not face and neck BCC, and obesity, diabetes mellitus and asthma may indirectly reflect the different role of past sunlight exposure to different body locations and variable etiologic pathways for BCCs according to body areas.

No full textIdiopathic atrophy of the nails: Clinical and pathological study of 2 cases
No full textBackground: Whether idiopathic atrophy ot the nails (IAN) should be considered a separate entity or a clinical variant of nail lichen planus is still controversial. Objective: We report here the pathological study of 2 patients with IAN. Methods: Our patients had similar clinical features consisting of severe nail atrophy with and without pterygium. Results: The nail matrix architecture was markedly deformed with complete disappearance of the keratogenous zone that was replaced by a 3- to 10-cell-thick granular layer. Conclusion: The hypothesis that IAN is an acute and self-limited variety of lichen planus is still the most presumable. Even though this hypothesis can not be definitely proven, it is nevertheless not excluded by the clinical and pathological findings of our cases. © 1995 S. Karger AG, Basel
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
The Impact of Gitelman Syndrome on Cardiovascular Disease: From Physiopathology to Clinical Management
No full textGitelman syndrome (GS), or congenital hypokalemic hypomagnesemia hypocalciuria with metabolic alkalosis, is a congenital inherited tubulopathy. This tubulopathy is associated with disorders of water-electrolyte homeostasis, such as metabolic alkalosis, hypokalemia, hyponatremia, hypomagnesemia and hypocalciuria. GS has an autosomal recessive inheritance. The loss-of-function mutation involves the gene that codifies for thiazide-sensitive sodium-chloride co-transporter located in the distal convoluted tubule. The physiopathology of the syndrome is characterized by activation of the renin-angiotensin-aldosterone system (RAAS) with a low plasmatic concentration of angiotensin-II. Despite hyper-activation of RAAS, average or low blood pressure is detected in association with low peripheral resistance and reduced response to vasopressors. Clinical findings are brief episodes of fatigue, syncope, vertigo, ataxia and blurred vision; sudden cardiac death might occur. This review aims to give insight into cardiovascular implications and management of GS
