Afebrile benign convulsions with mild gastroenteritis: a new entity?
No full textAfebrile seizures in children usually necessitate investigations in order to determine the etiology and estimate the prognosis. Recently, convulsions that are described as benign but afebrile have been documented in children, in association with diarrhea, and are now recognized as a distinct entity. Benign afebrile seizures with mild gastroenteritis are defined as convulsions accompanying symptoms of mild diarrhea without dehydration or electrolyte derangement and without fever before and after the seizures in healthy children without meningitis, encephalitis or encephalopathy. The convulsions are short, symmetrical, generalized tonic-clonic seizures, occurring in clusters. Laboratory studies (full blood count, blood glucose, creatinine, serum electrolytes, cerebrospinal fluid, bacterial and viral cultures) are usually normal, and other investigations (neuroimaging and electroencephalogram) are not necessary. Prognosis is always favorable (normal psychomotor development, no recurrences of seizures), and anticonvulsant therapy is not warranted. Recognition of this benign infantile convulsion avoids extensive evaluation and long-term anticonvulsant therapy; physicians may reassure the parents regarding the lack of long-term sequelae. In conclusion, this type of seizure seems to be a new entity, but it awaits a correct place in the large group of infantile convulsion disorders

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
The effect of recurrent severe hypoglycemia on cognitive performance in children with type 1 diabetes: a meta-analysis.
No full textThe purpose of this study was to investigate the existence and extent of cognitive impairment in type 1 diabetic children with episodes of recurrent severe hypoglycemia, using meta-analysis to synthesize data across studies. The meta-analysis sample included: 441 children with diabetes and recurrent severe hypoglycemia, 560 children with diabetes and without recurrent severe hypoglycemia. Overall, children with type 1 diabetes and recurrent severe hypoglycemia had slightly lower performance than diabetic children without severe hypoglycemia, only in some cognitive domains: intelligence, memory, learning, and verbal fluency/language. Greater impairment was found in memory and learning. No impairment was found for motor speed. Our results seem to confirm the hypothesis that recurrent severe hypoglycemia has a selective negative effect on the children's cognitive functions. However, these results must be considered with caution taking into account factors such as small sample sizes, the different definitions of severe hypoglycemia, and the variety of neuropsychological tests used
