Sensory phenotype assessment in a young girl affected by congenital insensitivity to pain (CIPA)
No full textSensory phenotype was assessed in a young girl affected by congenital insensitivity to pain (CIPA) scheduled for an open surgical drainage. The sensory profile showed that only the Abeta fibers were functioning normally, whereas Adelta and C fibers did not respond to nociceptive stimuli. On the basis of these findings and the results of cardiovascular reflexes, she was submitted to abscess incision and debridement under midazolam sedation alone. She did not report pain or other discomfort during surgery. The sensory (and sympathetic) assessment may have a high potential value in planning anesthesia and analgesia in children with CIPA. This psychophysical procedure could be introduced as standard component of clinical evaluation before surgery
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
Acute mastoiditis in an Italian pediatric tertiary medical center: a 15 – year retrospective study
No full textAbstract Background Acute mastoiditis is the main suppurative complication of acute otitis media. Its incidence ranges from 1.2 to 4.2/100.000 children/year and a rise has been reported in the last years. There are controversial data regarding risk factors for mastoiditis and its complications. Aim of the study: to evaluate demographics and clinical characteristics of children with acute mastoiditis and to identify possible risk factors for complications. Methods We retrospectively reviewed medical charts of all the children aged 1 month-14 years admitted to our Paediatric Emergency Department from January 2002 to December 2016. Results One hundred forty-seven cases (97 males and 50 females) were included in the analysis, mean age was 4.8 ± 3.6 years and 28.2% of the patients were younger than 2 years. We found an increasing number of mastoiditis per year during the last 3 years of the study. Children younger than 2 years were less treated with antibiotics for acute otitis media or treated for a shorter period (p < 0.05), while they were treated at higher antibiotic’s dosage for mastoiditis (p < 0.01). Older children presented more frequently with symptoms such as earache or retroauricular pain (p < 0.0001, p < 0.001). We didn’t identify any risk factor for mastoiditis complications in our study. Conclusions Despite the introduction of pneumococcal vaccines, the incidence of acute mastoiditis in our population has not been reduced during the last years. We have to face all the reasons why this condition is still relevant, such as antibiotic resistance, new pathogens involved and a possible role played by the implementations of therapeutic acute otitis media guidelines restricting the use of antibiotics in this disease. A particular attention should be given to younger children where signs and symptoms may be less pronounced, therefore acute otitis media or mastoiditis may be misunderstood and appropriate treatment delayed
Vitamin A deficiency due to selective eating as a cause of blindness in a high-income setting
No full textVitamin A is a fat-soluble micronutrient involved in the regulation of several physiologic functions, such as visual acuity, epithelial tissue integrity, immune response, and gene expression, thus playing a crucial role in childhood growth and development. Although Vitamin A deficiency (VAD) in resource-limited settings is still an actual issue and represents the leading cause of preventable childhood blindness, its occurrence in highincome countries is rare, although possibly underdiagnosed because of its nonspecific early manifestations. A good awareness of VAD symptoms and risk factors could aid its early diagnosis, which is fundamental to undertake a prompt treatment and to prevent ocular complications. Nevertheless, the role of restrictive dietary habits, increasingly common in developed countries, is often overlooked in infants and children. We present a case of VAD with permanent ocular sequelae in a 5-year-old girl from a highincome country. In the case described, VAD ensued from a highly restricted diet, mainly limited to oat milk, which had been followed for more than 2 years. This child presented with ocular symptoms, opportunistic infection, anemia, poor growth, and a diffuse squamous metaplasia of the bladder; after commencing retinol supplementation, a gradual healing of clinical VAD manifestations occurred, with the exception of the ocular sequelae, which resulted in irreversible visual loss
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
