From Evidence-Based Medicine to Patient-Centered Medicine Legal medicine considerations about professional responsibility
No full textIntroduction: the adaptation of the guidelines to the specific case is not easy and it requires a significant effort by the of the physician.
Discussion: we found many criticism, but particularly a logic (the patient-centered medicine) most appropriate to reasoning of legal medicine.
Conclusion: the patient-centered medicine is a medicine that take into account the individual case because it best meets the needs of law and with which the evidence based medicine must be integrated.Introduction: the adaptation of the guidelines to the specific case is not easy and it requires a significant effort by the of the physician.

Galactocele after aesthetic breast augmentation with silicone implants. An uncommon presentation
No full textBackground: Breast augmentation is one of the most frequently performed esthetic operations. Galactorrhea and galactocele formation are both very rare complications. The real cause still remains unknown, but various risk factors have been well reported in the literature. This report concerns a case of postoperativegalactocele following bilateral breast augmentation via the inframammary approach with dual-plane insertion of implants, which is usually considered a protective approach in terms of risk factors for induction of postoperative galactorrhea. Methods: The patient had no significant surgical, gynecological or medical history, including galactorrhea or hyperprolactinemia, and did not present any chest wall abnormalities. There has been no use of oral contraceptives or any other drugs. After the surgical procedure, the patient presented with infection-like symptoms, for which galactorrhea or galactocele was initially not considered, mainly for the absence ofspecific risk factors. Results: After antibiotic and bromocriptine therapy, her breast returned to normal, with no pain, inflammation, enlargement or esthetic alterations. After 6 months of follow-up, the patient did not present any abnormality and she was satisfied with the result. Conclusion: With our report, we want to underline that galactorrhea and galactocele cannot be ruled out, even in patients with no risk factors and with procedures considered as “protective.” With a fast diagnosis and a specific therapy, implants and final result can be rescued.

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
Acral lentiginous melanoma. A retrospective study
Full text linkBackground: Acral lentiginous melanoma (ALM) carries one of the worst prognoses among other subtypes. This malignant tumor is found on the distal limbs and is usually detected at late stages. Hereby, the authors present their experience on this melanoma subtype. Methods: A retrospective study was conducted. Data were extracted from patients’ medical records and from phone interviews. Results: A total of 43 patients were included in the study. The main signs and symptoms disclosed by the patients were bleeding (41.9%), size greater than 6 mm (41.9%), change in size (37.2%), change in shape (30.2%), rise above the surface of the skin (27.9%), change in color (20.9%), irregular borders (16.3%), and inflammation (16.3%). The first healthcare professional consulted was a general practitioner or a dermatologist in the majority of cases (88.3%). Only 44.2% of the patients were sent by their first physician for a biopsy, whereas 30.3% were sent by the 2nd physician. 14 patients underwent biopsy within 1 month from the first appointment with a physician, while 20 patients within 3 months and 9 patients within 6 months. Only 7 patients sought medical attention in the first 3 months; 21 patients sought medical care between 3 months and one year from the appearance of the lesion, while the remaining 15 patients waited more than a year. Conclusions: One of the major issues found in ALM is represented by the diagnostic delay; this may be due to either the patients or the physicians’ failure to recognize warning signs
Is body-contouring surgery a right for massive weight loss patients? A survey through the European Union National Health Systems
No full textBackground: Obesity is pandemic nowadays, and hanging skin with consequent functional and psychological impairments is a common price to pay for massive weight loss. Plastic surgery in postbariatric patients represents a fundamental step to regain possession of a positive self-image. The authors aimed to investigate how EU countries’ National Health System (NHS) behaves regarding reimbursements for body-contouring procedures after massive weight loss. Methods: A 1-item survey was sent to contacts found on the NHS official Web sites of 27 EU countries. The question focused on postbariatric surgery practice and investigated the accessibility criteria for NHS coverage concerning body-contouring procedures after massive weight loss. Results: Responses were collected between January 2020 and February 2020. Response rate was 65%, and access criteria to NHS coverage for postbariatric surgery presented great variation across EU countries. Only one country presented an NHS with no coverage for postbariatric surgeries. Conclusions: Despite the conspicuous variability found among the EU NHS, none of them admit reimbursement in cases of merely aesthetic procedures: postbariatric patients need to display functional or health impairments due to the extensive weight loss. The results of the current study describe a complex situation among EU countries, but a common lead towards postbariatric patients’ care shows off. The ultimate goal of bariatric patient’s healing should be full restoration of physical and psychological well-being. NHS of EU countries are facing this increasing request in various ways, and more studies should be performed in order to understand which is the best approach. Level of evidence: Not ratable
