    Objective: The objective of the study was to compare the outcomes of the incidence of nausea/vomiting and other complications along with the time taken for discharged in patients undergoing Thoracic Epidural Analgesia (TEA) and General Anaesthesia (GA) for breast oncological surgeries. Background: GA with or without TEA or other postoperative pain-relieving strategies remains the traditional anesthetic technique used for breast oncological procedures. We initiated the use of high segmental TEA for patients undergoing these procedures in our hospital. Methods: Eighty patients undergoing breast oncological procedures performed by one surgical team were randomly allocated into two groups receiving TEA and GA. The Chi-square test and Fisher's exact test were used for categorical parameters, paired t-test and Student's t-test was used for continuous measurements. Results: In comparison with GA, TEA was associated with lesser incidence of complications of nausea/vomiting. In lumpectomy with axillary node dissection, 1 out of 18 patients (5.55%) in the TEA group had nausea/vomiting, while 11 out of 19 (57.8%) of the GA group had similar symptoms (P < 0.001). The discharge rate for the thoracic epidural group was 12 out of 18 by day 3 (66.6%) while all patients in the GA group required more than 3 days of hospitalization (P < 0.001). Conclusion: Thoracic epidural anesthesia is a safe technique and its use in breast oncological procedures could improve patients' recovery and facilitate their early discharge to home

    Staged total penile reconstruction using flap prefabrication and arteriovenous loop

    Loss of penis due to injury or disease is physically and psychologically devastating to any male. While the technique of penile reconstruction continues to evolve in conjunction with the evolution of flaps in reconstructive surgery, the free tissue transfer using radial artery forearm flap (RAFF) in a single stage is recognized as the most preferred method at present. However, to avoid the complications often seen in such single-stage method, we used a novel two-stage technique for total penile reconstruction in two cases after penile loss. We prefabricated the neophallus in the forearm and constructed saphenofemoral arteriovenous loop in the groin in the first stage to allow all the suture lines to heal and provide for easy and reliable recipient vessels. The neophallus was transferred after 4 weeks and vessel anastomoses done conveniently in the groin with adequate sized vessels with robust inflow. Both the patients recovered well without any need for urinary diversion and quickly attained the ability to pass urine in standing position. We offer that the two-stage method of penile reconstruction using free RAFF is reliable, easy to perform and can avoid many of the complications seen with single-stage reconstruction

    Background: Care bundles are an effective means of reducing catheter-associated urinary tract infection (CAUTI) when they are implemented with high impact interventions. Care bundle approach only works when every element of the bundle is implemented for every appropriate patient, every time and with high impact. Aim: This study aims to study the efficacy of CAUTI Care Bundle and of infection control nurse (ICN) in reducing the incidence of CAUTI in a zonal hospital. Materials and Methods: The study was with an initial baseline phase (observational) of 8 months followed by an intervention Phase of 21 months. The intervention phase was further divided into intervention Phase I (8 months) and intervention Phase II (13 months). Intervention Phase I included a multidimensional approach of education and training of health-care staff for catheter management and prevention of CAUTI and implementation of catheter care bundle. In intervention Phase II education of health-care workers and implementation of catheter care bundle was done under constant supervision and guidance of ICN. Results: We recorded a total of 834 urinary catheter days: 309 in baseline phase, 314 in intervention Phase I, and 211 in intervention Phase II. It was found that the incidence rate of CAUTI, measured as episodes per 1000 catheter days is 64.72 in baseline phase, 25.47 in intervention Phase I, and 18.95 in intervention Phase II. The catheter care bundle approach along with education of the staff reduced the CAUTI incidence by 60.64 and when the same was applied under the constant supervision of ICN for the CAUTI reduction rate was clinically significant with 70.72. Conclusions: The catheter care bundle approach along with the education of the staff reduced the CAUTI incidence by 60.64 episodes/1000 catheter days and when the same was applied under constant supervision of ICN for the CAUTI reduction rate was clinically significant with 70.7

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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
