No full textUse of a vibration tool to reduce pain from growth factors injection in the treatment of androgenetic alopecia: a randomized controlled trial
No full textObjective: local anesthetics (cream or tape) are often used to reduce pain associated with injection procedures, but might not be sufficiently effective or applicable when treating the scalp for androgenetic alopecia with growth factors injection. The aim of this randomized controlled trial was to determine whether the application of microvibratory stimulation during scalp injection would decrease pain reported by patients. Methods: fifty consenting patients scheduled to undergo growth factors injections for the treatment of androgenetic alopecia were recruited. The study period was 12 months, with a single surgeon performing all procedures. The treatment area was divided in two equal halves and subjects were randomized to receive injections with vibration given by a mini massager in the first zone, and then no vibration in the second zone, or viceversa. At the end of the session, all patients were asked to express the level of discomfort of each procedure, using the Numeric Rating Scale. Results: out of the 50 patients, 39 reported that vibration relieved the pain, 10 stated that it had no effect, and 1 complained that it made the pain worse. Vibration did not affect the safety of the injections. The average Numeric Rating Scale scores for the no-vibration and vibration injections were 5.34 and 4.16 respectively (p≤ 0.05). Conclusions: vibration reduces pain associated with needling/injection of the scalp. The Gate Control Theory of Pain explains this effect
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
D'Andrea's disease (angiomegaly): a currently well-defined nosological entity
No full textIn 1997 D Andrea et al. described a new nosological entity the characteristics of which consisted of lengthening, dilation and tortuosity of blood vessels, arteries or veins, less prominent, but also less circumscribed than an aneurysm. This condition does not necessarily imply specific aneurysm formation although aneurysms at multiple sites are a frequent observation. The term used by authors for angiomegaly of the venous system was venomegaly and the analogous condition of the arterial system was termed arteriomegaly. Although tortuosity and dilation of arteries and veins have been widely reported, suggesting a systemic disorder which affects the structural integrity of all vessels, most papers dealing with this intriguing condition did not describe any alterations in the components of vessel walls. In the present paper, the authors describe a well-defined condition, D Andrea s Disease (or DD, in this article), analyzing its salient morphological and clinical features and clarifying this pathological condition as a distinct and now well-defined nosological entity
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
