Neonatal neck mass in identical twins: An unusual presentation
No full textIdentical twins were noted to have a soft asymptomatic neck mass, each on the opposite side, at 1 week of age. The mass took a dramatic course 1 week later to present as a neck abscess, yet without systemic symptoms. Ultrasonography was highly suggestive of an infected lymphatic malformation (cystic hygroma). Intravenous antibiotics and drainage (aspiration-incision and drainage) resulted in resolution of the mass and no recurrence at 18 months follow-up. The concept of spontaneous involution of lymphatic malformation (cystic hygroma) is discussed as well as the management of neck abscesses in infancy.

Microdebrider-assisted partial tonsillectomy: Short- and long-term outcomes
No full textMicrodebrider-assisted partial tonsillectomy has gained popularity in recent years. However, no prospective long-term follow-up exists in the literature and the risk of increase in tonsillitis is still a concern. We conducted a prospective randomized controlled study to assess the short-term benefits of microdebrider-assisted partial tonsillectomy (group 1) compared to electrocautery-assisted total tonsillectomy (group 2), to monitor the durability of the improvement and watch for any change in the rate of tonsillitis. Patients with symptomatic tonsillar hyperplasia were included and underwent either technique of tonsillar surgery. Duration of operation, amount of intra-operative blood loss, immediate and late complications, postoperative pain, return to normal activity and diet, and relief of obstructive symptoms were measured. Recurrence of symptoms and change in rate of tonsillitis in group1 were monitored. We studied 143 patients, 77 in group1 and 66 in group2. There was no significant difference in the surgical time (P 0.05) or postoperative bleeding (P 0.05) but more blood loss in group1 (P 0.05) and more dehydration in group2 (P 0.05) were encountered. All patients had complete relief of symptoms. Group1 returned earlier to normal activity (2.19 vs. 5.71 days; P 0.05), to normal diet (5.28 vs. 8.16 days; P 0.05) and needed less frequent analgesics (2.14 vs. 6.1 days; P 0.05). More than two-thirds of group1 and less than one-third of group 2 were pain free after day 3. Most group 1 parents (96.1percent) were highly satisfied, at initial follow-up, regarding the decision to perform the surgery in contrast to group 2 parents (19.7percent). No recurrence of symptoms and no increase in rate of tonsillitis were noticed among group 1 after 20 months mean follow-up (median 20.6, range 1-36.2 months). Group 1 showed short-term benefits over group 2 and maintained the resultant improvement on the long-term with no infectious drawbacks. © 2007 Springer-Verlag.Chang KW, 2005, OTOLARYNG HEAD NECK, V132, P273, DOI 10.1016-j.otohns.2004.11.002; Derkay CS, 2006, OTOLARYNG HEAD NECK, V134, P114, DOI 10.1016-j.otohns.2005.10.039; El-Bitar MA, 2002, ARCH OTOLARYNGOL, V128, P425; HALL GM, 1984, LARYNGOSCOPE, V94, P1381; Hultcrantz E, 1999, INT J PEDIATR OTORHI, V51, P171, DOI 10.1016-S0165-5876(99)00274-8; Hultcrantz E, 2004, LARYNGOSCOPE, V114, P871, DOI 10.1097-00005537-200405000-00016; JOHNSON F, 1962, ARCHIV OTOLARYNGOL, V75, P127; Koltai PJ, 2003, OTOLARYNG HEAD NECK, V129, P532, DOI 10.1016-S0194-5998(03)00727-7; Koltai PJ, 2002, LARYNGOSCOPE, V112, P17; Lister MT, 2006, ARCH OTOLARYNGOL, V132, P599, DOI 10.1001-archotol.132.6.599; Nelson LM, 2000, ARCH OTOLARYNGOL, V126, P736; PHYSICK PS, 1828, AM J MED SCI, V2, P116; Pizzuto MP, 2000, INT J PEDIATR OTORHI, V52, P239, DOI 10.1016-S0165-5876(00)00293-7; Sobol SE, 2006, ARCH OTOLARYNGOL, V132, P270, DOI 10.1001-archotol.132.3.270; Solares CA, 2005, INT J PEDIATR OTORHI, V69, P21, DOI 10.1016-j.ijporl.2004.07.006; SORIN A, 2004, LARYNGOSCOPE, V114, P294; Temple RH, 2001, INT J PEDIATR OTORHI, V61, P195, DOI 10.1016-S0165-5876(01)00553-5; Walker RA, 2001, OTOLARYNG HEAD NECK, V125, P449, DOI 10.1067-mhn.2001.119325; Whillis SS, 1910, LANCET, V2, P87519171
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
Spontaneous sublingual haematoma: A rare entity
No full textSublingual haematoma, also known as pseudo-Ludwig phenomenon, is an entity commonly described in patients on anticoagulation therapy. Spontaneous sublingual haematoma is a rare subtype. It is thought to be due to aneurismal changes in the facial or lingual arteries, occurring mostly in the elderly hypertensive population. Two case reports of spontaneous sublingual haematomas have been reported so far in the literature. Both cases were elderly patients and presented with a sublingual mass and elevation of the floor of the mouth. One patient was intubated whereas the other underwent an emergency tracheotomy. The authors present the third case of spontaneous sublingual haematoma that was afebrile and had a sudden onset of sore throat that progressed to dyspnoea and required a life-saving tracheotomy. The patient recovered quickly postoperatively and could be discharged home in a couple of days and was decannulated in 1 week. No recurrence of the haematoma was noticed on follow-up after 1 year.

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
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
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
