Acute hemorrhagic edema of infancy. Clinical picture of leukocytoclastic vasculitis
No full textAcute hemorrhagic edema of infancy (AHEI; synonyms Finkelstein disease, idiopathic Seidlmayer's purpura), which occurs mainly in children under 2 years of age, was for a long time considered to be a rare form of Henoch-Schonlein purpura. Meanwhile, this form of leukocytoclastic vasculitis is a separate entity in the literature, with the classic triad consisting of fever, edema, and rosette-like or circular purpura. The disease is self-limiting; however, serious differential diagnoses such as Waterhouse-Fridrichsen syndrome should certainly be excluded. Blood count and coagulation parameters are not changed. Attention should be paid to rare but acute complications
Serotonergic Overstimulation in a Preterm Infant After Sertraline Intake via Breastmilk
No full textThe selective serotonin reuptake inhibitor (SSRI) sertraline is widely used as an antidepressant agent during pregnancy and lactation because of its low placental transfer and low level of excretion into breastmilk. Symptoms such as neonatal abstinence syndrome and serotonergic overstimulation have been reported after in utero exposure to SSRIs. These symptoms are self-limiting and usually peak within the first 48 hours after birth. In our case, a preterm infant was exposed to sertraline and its main metabolite desmethylsertraline in utero and via breastmilk. Beyond the first 48 hours after birth, the infant developed increasing clinical signs of serotonergic overstimulation associated with substance intake via breastmilk, until breastfeeding was discontinued on postnatal Day 9. In spite of a low calculated daily substance intake via breastmilk, the serum substance levels of the preterm infant were within the therapeutic range of adults. The serotonergic overstimulation may be explained by the limited metabolic capacity of the infant and the immaturity of the blood-brain barrier

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
Giant Umbilical Cord Edema Caused by Retrograde Micturition through an Open Patent Urachus
No full text A giant umbilical cord is a rare finding in mature newborns and originates from different developmental etiologies. We report on a case of a mature female newborn presenting a 50 × 8–cm giant umbilical cord without further malformations. Antenatal sonographic findings of a diffuse giant umbilical cord, elevated creatinine levels of 1.3 mg/dL in umbilical cord edema, gross and histopathological findings of allantoic remnants, and umbilical urinary discharge lead to the diagnosis of a patent urachus with retrograde micturition into the umbilical cord. Postnatal surgical repair was required. In antenatal sonography, cystic and diffuse changes should be considered in the differential diagnosis of a giant umbilical cord. In cases of diffuse enlargement, elevated umbilical creatinine can support the diagnosis of a patent urachus with open leakage into the Wharton's jelly. Appropriate surgical management is required. </jats:p
