No full textAmbroxol-Induced Focal Epileptic Seizure
No full textIt is well known that in epileptic patients some compounds and different drugs used for the treatment of comorbidities can facilitate or provoke seizures, this evidence regarding a wide spectrum of pharmacological categories. The potential facilitating factors usually include direct toxic effects or pharmacological interactions of either active ingredients or excipients. We report the case of a patient with drug-resistant epilepsy who experienced focal epileptic seizures, easily and constantly reproducible, after each administration of a cough syrup. This is, to our knowledge, the first electroencephalogram-documented case of focal epileptic seizures induced by cough syrup containing ambroxol as active ingredient

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Epilepsy, unawareness of seizures and driving license: The potential role of 24-hour ambulatory EEG in defining seizure freedom
No full textIntroduction: Seizures represent a potential source of accidents/death. Permission to drive may, therefore, be granted in a seizure-free period. Laws and regulations regarding this issue vary widely, and the onus of reporting seizures ultimately rests on the individual. Unfortunately, as some patients are unaware of their seizures, their reports may be unreliable. Methods: In this retrospective study, we selected, from a group of 1100 consecutive patients, 57 cases (26 males/31 females; mean age: 42.5. years) in whom the AEEG documented ictal events (UIEs) not reported in a self-kept diary. By means of a simple questionnaire, we interviewed all these patients to collect information on driving licenses. We, thus, assessed how many of these patients (both drug resistant and seizure free) drove regularly. Results: Our study shows a relatively large number of patients with epilepsy and UIEs. Fifteen patients suffered from idiopathic generalized epilepsy (IGE) while 42 had partial epilepsy (PE). The patients were seizure free in 21 cases and 36 had drug-resistant seizures. Many patients in both these subgroups had a driving license and drove normally (active driving in 12/36 drug-resistant patients and in 18/21 seizure-free patients). Worthy of note is the finding that an "apparently" seizure-free group of patients drove regularly. Conclusions: This study revealed a large number of patients (both drug resistant and seizure free) with AEEG-documented UIEs. This finding highlights the usefulness of AEEG in clinical practice as a means of more accurately ascertaining seizure freedom and supporting decisions involving the renewal or granting of a driving license. © 2012 Elsevier Inc
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
