How to Use Energy Devices and their Potential Hazards
No full textModern thyroid surgery has been substantially modified by the impact of devices/instruments that, using different forms of energy (mainly radiofrequency and harmonic technology), allow a bloodless dissection of the surgical field. Among many advantages, these instruments are responsible, for example, for the significant reduction of the incision size, which may be one of the main concerns of patients undergoing thyroid surgery. Nevertheless, even if they are sa-fer than the common monopolar electrocautery, to be properly used all these instruments have a learning curve necessary to avoid damage that may affect the patient's quality of life. This chapter analyses the technology behind the more commonly used devices, and discusses the results and advantages obtained when using them to perform a thyroidectomy. © 2013 John Wiley & Sons, Ltd
Minimally Invasive Techniques Performed Through the Neck Access
No full textMinimally invasive video-assisted thyroidectomy currently represents the most widely performed technique for minimally invasive thyroidectomy in western countries. The particular complications of the minimally invasive video-assisted thyroidectomy technique will be discussed. We will focus specifically on the relevant aspects and management of well-known complications (e.g. postoperative bleeding) during and after this minimally invasive procedure, and on how to avoid them. © 2013 John Wiley & Sons, Ltd
Minimally Invasive Video-assisted Thyroidectomy
No full textThe minimally invasive video-assisted thyroidectomy (MIVAT) was developed in Pisa in 1998, and described in 1999. It has now become the most widespread minimally invasive technique for thyroidectomy throughout the world. This technique cannot be applied to every patient undergoing thyroid surgery but has precise indications, mainly in terms of size of the thyroid gland and nature of the thyroid disease. Only low and intermediate differentiated thyroid cancers under 2cm should be selected for MIVAT. © 2013 John Wiley & Sons, Ltd
Open Access Of Research: Which Role In The Processes Of Evaluation? Experience By The Agenzia Nazionale Di Valutazione Del Sistema Universitario E Della Ricerca (Anvur)
Full text linkThis article focuses on Open Access and Research Evaluation, and the experience by the Italian National Agency for the Evaluation of Universities and Research Institutes (ANVUR). It is an updated version of the work presented at the Workshop "Open Science: new models of scientific communication and research evaluation", organized by Virginia Valzano at the University of Salento, on January 30, 2019
Postoperative follow up in patients showing no evident residual disease - Cut-offs for imaging/ intervention
No full textThe European Group generally agrees with the American guidelines on the issue of the indications for additional surgery in patients with recurrence of medullary thyroid cancer. The discussions have been focused mainly on the postoperative follow-up, where some European experts feel that a postoperative calcitonin-stimulating test is of some importance in assigning the patient to the "Cured" or "Non-cured" group immediately after surgery. A part of the European group feels that a negative calcitonin-stimulating test might lead to a less intensive follow-up in the late follow-up of these patients
Video-assistive minimally invasive surgical procedures in the treatment of thyroid in children and adolescents
No full textMinimally invasive video-assisted (MIVA) surgery of the thyroid is now widely accepted by endocrinel surgeons, especially in adult age. This report describes indications, limits, technical aspects and results of MIVA in 10 young patients (mean age 16 years, range 11-18) enrolled in a study of 213 patients (mean age 45 years, range 11-81) operated with this technique, from October 1998 to August 2001, in the Department of Surgery at the University of Pisa. Young patients were submitted to surgery: 8 lobectomies (6 for microfollicular lesions and 2 for adenomas functionally autonomous) and 2 total thyroidectomies for papillary carcinoma. No case has been converted in "open" surgery and no post-operatory complications have been observed. Elective indications of MIVA are the volume of the nodule and the istological type. This technique cannot be performed in voluminous goiters, in medullary carcinomas and in scarcely differentiated carcinomas. Minimally invasive video-assisted surgery of the thyroid, in our experience, represents a reliable technique also in pediatric age
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
