Was Tiepolo’s wife affected by Graves' disease?
No full textTiepolo (1696–1770) was an Italian Rococo painter and printmaker, and is now considered to be one of the most important members of the 18th-century Venetian school. The muse that lent her face to Cleopatra and inspired many Tiepolo’s works was his beloved wife, Maria Cecilia Guardi. Because of her appearance, we cannot rule out that she suffered from Graves' disease, an autoimmune condition that is characterized by goiter, exophthalmos and restlessness
Modular Approach to Open Partial Horizontal Laryngectomy: Step-by-Step Anatomic Dissection
No full textOpen partial laryngectomies still play an important role in contemporary conservative management of laryngeal cancer. A comprehensive and systematic classification of open partial horizontal laryngectomies (OPHLs) was presented by the European Laryngological Society working committee in 2014. The aim of this video is to show the main surgical steps in OPHL using a cadaveric dissection and to explain the modular approach for removal of laryngeal tumors
Role of the temporoparietal fascia free flap in salvage total laryngectomy
No full textThe procedure for salvage total laryngectomy (STL) is burdened by a high rate of postoperative complications as a result of delayed wound healing in previously irradiated tissue. Several observational studies have investigated the role of prophylactic vascularized flaps to aid pharyngeal closure after STL and prevent the development of PCF. The use of a temporoparietal fascia free flap (TFFF) as an overlay flap for STL has been described previously in two published studies and both sets of authors agreed that the most obvious benefit of the TFFF in STL is a reduced PCF rate with low site morbidity and good functional outcomes. The aim of this video is to illustrate the use of the temporoparietal fascia flap to provide an adjunctive reinforcement layer in the reconstruction of the pharynx
Quality of Life Evaluation After Trans-Nasal Endoscopic Surgery for Skull Base Tumors
No full textAbstract Background: The excellent surgical results obtained with transnasal endoscopic approach to the anterior skull base (ASB) are universally recognized; less is known about the quality of life of patients after surgery. Objective: The aim of this study is to analyze the quality of life of patients after endoscopic transnasal surgery for the treatment of neoplasms of the ASB. Methods: We conducted a retrospective review of patients who underwent transnasal endoscopic surgery for treatment of ASB tumors at the Tertiary Referral Center University Hospital of Verona. All patients were asked to complete the Anterior Skull Base Questionnaire (ASBQ), the Skull Base Inventory (SBI), and the Sino-nasal Outcome Test – 22 Items (SNOT-22) after surgical treatment. The study population was divided into subgroups; a statistical analysis of the overall results and of the different questionnaire domains was performed. Results: 51 patients were enrolled in this study. The average score was 3.04 for ASBQ, 4.05 for SBI and 28.88 for SNOT-22. Analysis of the overall results for the ASBQ showed a lower quality of life in patients after recurrent surgery and in female patients. The SBI showed similar results in relation to recurrent surgery and radiotherapy. Similarly, the results for SNOT-22 highlighted the negative impact of recurrent surgery and radiotherapy. Conclusion: Our results confirmed that the endoscopic transnasal approach shows excellent results not only in terms of surgical outcome, but also for the possibility of ensuring a good QoL after treatment. Recurrent surgery and radiation treatments were the most important negative prognostic factors
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
Versatility and aesthetic performance of the submental flap for reconstruction of skin defects in head and neck
No full textThe submental flap (SMF) is a reliable option for head and neck reconstruction. It is a pedicle flap based on the submental artery and vein, divisions of the facial pedicle. The purpose of this Operative Technique is to describe the step-by-step setup of the submental flap for reconstruction of the preauricular region and to briefly examine its versatility and range of choices in skin and soft tissue defect reconstruction (see Supplemental video in the online version of the article). The harvesting of the SMF provides an aesthetically acceptable result for both the donor and reconstructed sites. The main advantages of the flap are its excellent color and texture match to the tissue in the cheek, and the possibility of restoring pilosity in male patients. In the opinion of the authors, the SMF is one of the best reconstructive alternatives for defects in the lower two-thirds of the face in elderly male patients
Expanded transcanal transpromontorial approach for vestibular schwannoma
No full textThe expanded transcanal transpromontorial approach (ExpTTA) is indicated for removal of Koos stage I and II Vestibular Schwannoma (VS). The ExpTTA is a combined endoscopic and microscopic technique allowing direct access to internal auditory canal (IAC) and cer- ebellopontine angle (CPA) without extended bone removal, as required by the traditional approaches
The energy and environmental plan of a province in the North East of Italy
No full textThis paper focus on Local Authorities and their key role in promoting sustainable development patterns. Energy Action Plan is the political-administrative tool to define the framework in which the different proposed actions are integrated.
It describes a methodological approach in a fragmented context, such as Italy, characterized by small towns with less than 10’000 inhabitants that often lack of technical skills. The paper focus on Provinces and how they provide a platform for coordinating and boosting local actions. This paper describes how Local Energy Agency created a pool of experts coordinated by the university to develop a roadmap of strategies to achieve their goals in a territory of 900’000 inhabitants and 104 city councils.
In this paper the methodology for the definition of the current energy consumption defined on the base of statistical analysis is shown; the energy consumption has been divided into sectors and energy vectors. Afterwards, based on identified growth trends, energy saving potential and enhance renewable energy have been evaluated, identifying objectives and suggesting alternatives to achieve different scenarios.
Finally the paper focuses on the way in which the plan is elaborated in order to provide a proper communication for promoting actions to local stakeholders
