A novel method to medicate local cv flaps in nipple reconstruction
No full textBesides surgical technique related variables, post-operative care after nipple reconstruction with CV flaps is important for an satisfactory final result. We present a novel method to prepare a protective and sealing medication in order to minimize traumas to the new nipple. We found the silicone cap plunger of a 50cc syringe suitable for our purpose. It was applied over a non-adherent dressing and TNT gauze to avoid decubitus and fixed it with a steri-strip before covering with a sticking plaster. Analyzing 118 nipples casistic, reconstructed with a CV flaps technique, between January 2011 and June 2012 and medicated with the presented technique in the last six months considered, we noticed a reduction in partial loss of flap vitality and nipple reabsorption. The main advantages of the dressing technique we propose are the ease and rapidity in the preparation and availability of all materials used in every operation room or outpatient clinic. We believe that our technique of medication may reduce traumas to delicate vascularization of the new nipple, avoiding the partial or total loss of vitality and reabsorption of the flaps
Surgical management of macroglossia: Discussion of 7 cases
No full textOBJECTIVE: We present an overview of international literature concerning macroglossia-related etiology, clinical and instrumental diagnoses, surgical treatments, complications, and recurrences. Moreover, we present a series of cases of patients affected by macroglossia who have been treated surgically at the Department of Maxillofacial Surgery of the University of Rome "La Sapienza". METHODS: Between 1990 and 1999, only after attempts to solve this pathologic condition with medical and orthodontic treatment, we treated surgically a total of 7 patients (4 male and 3 female). The surgical techniques used were Köle glossectomy and Dingman and Grabb glossectomy. We analyzed the clinical and instrumental study and the surgical treatment, including possible complications and recurrences. RESULTS: After follow-up of a period from 2 to 9 years, macroglossia recurrences were absent, showing that the Köle and the Dingman and Grabb glossectomies are viable surgical options for treatment of macroglossia. CONCLUSION: The best therapy for each case macroglossia must be carefully evaluated, with the right medical therapy and orthodontic therapy attempted first and surgical treatment performed only when the first and second therapy fail. Moreover, surgical techniques must be chosen in accordance with the functional results that one wants to achieve and must be the most conservative technique to preserve the vascular-nerve bundl

Smokers: Risks and complications in abdominal dermolipectomy
No full textCigarette smoke has many detrimental effects on health, with consequences such as cardiovascular diseases, respiratory diseases, and tumors. In plastic surgery, these effects appear during the wound healing process. This retrospective study showed wound healing in 57 patients who had undergone abdominal dermolipectomy surgery. The patients were divided into two groups: smokers and nonsmokers. According to the results, smokers face a great complication risk for surgical wounds, which cause aesthetically more undesirable scars than observed in nonsmokers. The authors hypothesize that abstinence from smoking for 4 to 12 weeks before surgery would improve the quality of the scars
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
FRAIL scale as a predictor of complications and mortality in older patients undergoing reconstructive surgery for non-melanoma skin cancer
Full text linkThe aim of the present study was to determine the association between preoperative frailty and the onset of surgical complications in patients diagnosed with massive non-melanoma skin cancer subjected to plastic and reconstructive surgery. A retrospective analysis was performed on a cohort of 587 patients with non-melanoma skin cancer, selected on the basis of specific inclusion criteria, who were subjected to plastic and reconstructive surgery between 2005 and 2014. Frailty was scored using the FRAIL index, whereas postoperative complications were classified according to Clavien-Dindo criteria. By binary logistic regression, the odds and probabilities of complications were calculated as a function of increasing values of the FRAIL index. Two different logistic models were created, comparing absent/mild (Clavien grades 1st and 2nd) vs. moderate/severe complications or mortality (Clavien grades 3rd-5th; model A), or absent/mild/moderate complications (Clavien grades 1st-3rd) vs. severe complications or mortality (Clavien grades 4th and 5th; model B). The FRAIL index was an accurate predictor of surgical complications or mortality, with significant odds ratios and goodness of fit. In model A, FRAIL scores 4 and 5 were the most critical predictors of moderate/severe complications or mortality (37 and 94% probability, 0.6 and 17.3 odds, respectively), compared to score 3 (2% probability, 0.02 odds) or lower. In model B, FRAIL score 5 was the most critical predictor of severe complications or mortality, as it was associated with a 74.6% probability and 2.93 odds for these events. In conclusion, increasing FRAIL scores were associated with worsening surgical outcomes for patients with non-melanoma skin cancer undergoing plastic/reconstructive surgery. A low rate of surgical complications was observed in pre-frail and frail patients up to FRAIL score 3
