Use of NPTWi in Fournier's gangrene
No full textAim: Fournier's gangrene (FG) is defined as a fulminant form of infective necrotizing fascitis of the perineal, genital or perianal regions. Even with appropriate treatment approaches, mortality is high as 4 to 67%. There have been many advances in management of Fournier gangrene including use of vacuum assisted closure and hyperbaric oxygen therapy.
Methods: a 72 y.o. male with swelling, redness, pain on palpating and necrosis of the penis, scrotum and perineal area including the perianal area, with diabetes mellitus type II, previous non Hodgkin lymphoma recent surgery for perianal fistula, was admitted in our clinic. Because of the extensive involvement of the anus and its sphincter was necessary, as the first surgical time, the packaging of a terminal colostomy on sigma. After that, he underwent radical surgical debridement with excision of all necrotic material (fig1). Have been made abundant washing with hydrogen peroxide and betadine. Was used negative pressure wound therapy with controlled instillation of fluids (NPTWi)(fig2). The treatment was then completed with hyperbaric oxygen therapy. This treatment was performed for 40 days until discharge.
Results: the surgical treatment associated with NPTWi and hyperbaric oxygen therapy have allowed the resolution of the septic and an almost complete wound healing (fig3).
Conclusions: Early recognition and aggressive surgical excision are mandatory for success in patients with Fournier's gangrene. The use of NPTWi in the treatment of Fournier's gangrene improves clinical outcomes and reduces hospital stay
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
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
Histologic considerations about a rare case of recurrent incisional hernia on McBurney incision
Full text linkAIM: Incisional hernias are often related to longitudinal or transverse laparotomy with an incidence that rises from to 2 to 23 %. The oblique incision often used to surgically treat acute appendicitis has little probability to develop incisional hernia with an estimated incidence less than 2%. Some series report 0.1 - 0.9% of it. Anatomic, physiologic and histologic factors have been implicated in herniation development, such as intra-abdominal pressure or alteration on tissue components; many different risk factors can be taken into account to justify this rare condition such as female gender, diabetes, peritonitis, abscess or appendiceal phlegmon as the cause of the first operation, wound infection, seroma, use of cutgut to suture aponeurosis, interrupted suture to the aponeurotic layer.
MATERIAL OF STUDY: We present the rare case of young man who underwent surgical operation of acute appendicitis. Mc Burney incision was performed. Successively he underwent re-operation for incisional hernia developed upon McBurney incision and then "recurrence" of the same one.
DISCUSSION AND CONCLUSION: Histological analysis of scar tissue was done. Alteration on histological pattern protein expression was discovered
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
A rare case of abdominal cocoon
Full text linkAbdominal cocoon is a rare cause of intestinal obstruction usually diagnosed incidentally at laparotomy. It mani- fests by forming a membrane that typically encases the small bowel loops, leading to mechanical obstruction. Preoperative diagnosis is difficult. The etiology of this condition is not well understood; however, it is a form of chronic irritation and inflammation.
METHOD: A 33 years old male, from Bangladesh, presented to our emergency department complaining of abdominal pain, nausea, and vomiting. CT abdomen shows a picture of intestinal obstruction at the level of the small intestine. Intraoperative findings showed encapsulation of small bowel by a dense whitish membrane as a cocoon. Histological exam- ination showed a granulomatous peritonitis and Ascaris Lumbricoides in the bowel resected.
RESULTS AND CONCLUSIONS: The preoperative diagnosis of abdominal cocoon is difficult and hence, the diagnosis is usu- ally confirmed by laparotomy. Surgery remains the cornerstone in the management of abdominal cocoon. The pathogen- esis of abdominal cocoon remains elusive and has been associated with several conditions. The initial diagnosis of our patient was bowel obstruction from cocoon syndrome (CT and intraoperative findings) probably primitive, and only his- tologically proved granulomatous peritonitis associated with the presence of the parasite
