Technology spreading in healthcare: a novel era in medicine and surgery?
Full text linkSurgery and technological innovation have begun to move at the speed of light, with innovations and discoveries such as virtual reality, robotic systems, navigation surgery, and 5G networks radically revolutionizing the surgical world as well as the medical world in general, bringing significant benefits for healthcare professionals and patients alike. Technology will increasingly be a crucial element in surgical and medical development. This new therapeutic approach aims to enhance human–computer interaction by putting a new “patient” figure at its center. Multiple studies will be needed to demonstrate new advanced technological systems’ noninferiority to traditional patient approaches. Scientific societies, hospitals, and healthcare professionals cannot be found ill prepared for this revolution
Robotic surgery for gastric cancer: a review of the literature
Full text linkMinimally invasive surgery is increasing attention worldwide as an effective treatment approach in gastric cancer.In this context, several studies suggest that robotic technology may add some advantages over traditional laparoscopy, but the role of the robotic approach in the common surgical setting is still uncertain.The objective of this study is to review the current evidences in the literature comparing robotic surgery to other surgical approaches.Patients underwent robotic gastrectomy showed some benefits in terms of blood loss, postoperative morbidity, and length of hospital stay. No significant differences have been found in terms of survivals, while the number of lymph nodes retrieved with therobotic approach, expecially in the extraperigastric region, is generally higher than that of laparoscopy.The current studies in the literature suggest that the robotic gastrectomy is not inferior to the laparoscopic procedure and provides some surgical and clinical benefits
Radiofrequency and diathermy haemorrhoidectomy: early and late complications
No full textRadiofrequency and diathermy haemorrhoidectomy:
early and late complications
Aim: Milligan-Morgan haemorrhoidectomy is the most effective technique for the
surgical treatment of haemorrhoids, but is followed by severe pain, bleeding, soiling,
stenosis and slow return to daily activities. In order to prevent these consequences
new devices that use radiofrequency are used. We compared radiofrequency (RH)
and diatermy hemorrhoidectomy (DH) both for early and late complications.
Methods: Between 2012 and 2016, 82 patients were divided into two groups: 42 in
RH and 40 in DH. We analyzed: operative time, number of piles removed,
postoperative pain, bleeding, stenosis, soiling/minor incontinence, time off-work,
wound healing time and general satisfaction.
Results: Pain score were lower in the RH than DH, (mean VAS after 1 week 3,53 vs
4,22), such as operative time (RH 25 min vs DH 33 min). We removed on average
2,8 piles in RH vs 1,78 in DH. Temporary soiling/minor incontinence rates were
similar, while time off-work, wound healing time and overall satisfaction showed a
superiority of radiofrequency.
Conclusion: Radiofrequency haemorrhoidectomy is more effective than diatermy,
both for early and late complications, with faster recovery and better overall
satisfaction. Further randomized controlled trials are required to confirm these
preliminary results
Angiosarcoma of the breast: a new therapeutic approach?
Full text linkIntroduction Angiosarcomas are highly malignant endothelial cell tumors with poor prognosis. These can be due to breast cancer itself or to subsequent therapeutic modalities. No evidence-based guidelines exist concerning the ideal treatment of angiosarcomas. Presentation of the case We report the case of a 76-year-old woman who developed an exuberant and aggressive post radiation angiosarcoma of the breast and discuss different aspects of therapy for this disease. A total left mastectomy was performed, followed by a right mastectomy. The lesions into the chest wall, and multiple abdominal skin nodules were treated with local Electrochemotherapy (ECT) with intravenous bleomicin. Discussion No evidence-based guidelines exist concerning the ideal treatment of angiosarcomas. Electrochemotherapy (ECT) is an efficient palliative treatment of cutaneous and subcutaneous tumor nodules. It consists of the combination of a cytotoxic drug and electroporation, using appropriate electrical parameters; destabilization of the membrane is reversible, ensuring a high survival of permeabilized cells and the delivery of non-permeant molecules inside the cell. Conclusion Due to the rarity of the disease, prospective studies concerning adjuvant or neoadjuvant therapy are limited and no evidence-based guidelines exist. The response to chemotherapy seems to be poor. Treatment with ECT in addition to systemic chemotherapy achieves a complete response in all the lesions and improving patient body image perception
Completion total gastrectomy with intracorporeal robot-sewn esophago-jejunal anastomosis
Full text linkMany technical reports concern minimally invasive surgery for stomach cancer; however, there is poor evidence about employing this approach for gastric stump cancer, which can arise at the anastomotic site in patients who have undergone previous partial gastrectomy for benign diseases such as gastric ulcer. Such surgery was quite common before the introduction of proton pump inhibitors (PPIs), and so today, according to different statistics, gastric stump cancer can be revealed in up to 8% of these patients. This report seeks to highlight the possibility of employing a minimally invasive approach in patients who already had an operation for gastric resection.
The video shows technical notes about the hybrid laparoscopic-robotic approach performed in a patient who previously underwent open distal gastrectomy. Is the previous laparotomy an absolute or relative counterindication to reperform a surgery through a minimally invasive approach
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
