Overnight surgery in proctologia e tipo di anestesia: nostra esperienza su 320 pazienti

Nell’ambito della chirurgia proctologica, numerose evidenze dimostrano che l’ anestesia generale associata a quella loco-regionale presenta maggiori vantaggi rispetto all’anestesia spinale. Scopo del nostro studio è stato quello di verificare l’efficacia dell’ anestesia generale associata alla loco-regionale in una serie di pazienti affetti da malattia emorroidaria e ragade anale. Pazienti e metodi. Sono stati selezionati pazienti con emorroidi sintomatiche di III e IV grado e ragade anale senza storia di reazioni allergiche o suscettibilità farmacologica naropina, propofol e simili. Tutti i pazienti (gruppo A) sono stati sottoposti ad anestesia generale e loco-regionale. Nei pazienti di controllo (gruppo B) è stata praticata anestesia spinale. Alla fine di ogni intervento chirurgico sono state valutate le complicanze precoci e tardive mediante la classificazione da noi recentemente proposta. Risultati. Sono stati inclusi nello studio 320 pazienti, 240 operati per prolasso emorroidario e 80 per ragade anale. L’anestesia ottenuta è stata sempre soddisfacente e non sono state osservate complicanze post-operatorie permanenti. Fra quelle precoci si è osservata ritenzione urinaria nel 9% dei casi e dolore nel 30%. Fra le complicanze tardive sono state osservate dolore nel 8% e ritenzione urinaria nel 1% dei pazienti. In due casi si è formato un ascesso in corrispondenza del punto d’infiltrazione dell’anestetico locale. L’effetto dell’anestetico locale è durato in media circa 4-8 ore. Conclusioni. La tecnica anestesiologica locale con blocco posteriore, associata ad anestesia generale, si è dimostrata efficace per il trattamento delle più frequenti patologie proctologiche. Tale metodo ha comportato una bassa incidenza di complicanze precoci e tardive e una più rapida risoluzione dei postumi clinici legati all’intervento

Applying Mining Techniques to Analyze Vestibular Data

AbstractThe vestibular apparatus allows to perform audiological and equilibrium human functions and to capture movements with respect to gravity. Damages to the vestibular system causes diseases that can be measured by using Vestibular Evoked Myogenic Potentials (VEMPs) test. The test produces a lot of data that has to be collected and analyzed to allow a disease study and classification. We propose a framework that includes algorithms able to perform pathology distribution and classification. It has been tested on electronic patient records loaded from the University Hospital database. The software allows to manage the structure and framework and a blind application of one of the available classification techniques shows a relation among gender and vestibular apparatus disease

Small bowel cancer diagnosis: role of nuclear magnetic resonance

The diagnosis of small intestine tumors is challenging. Even in the era of modern medicine, standard approaches including echography, computed tomography-scan and conventional endoscopy are unable to reveal small bowel lesions. Video-capsule has substantially improved the evaluation of small bowel; however this procedure cannot be proposed to all patients and in particular to those experiencing intestine sub-occlusion. Nuclear magnetic resonance (NMR) of the abdomen is an additional diagnostic approach that offers high sensitivity in the identification of small bowel lesions. Here, we describe a case of small bowel neoplasia identified with NMR of the abdomen

TRANQUILLITY AREAS MAPPING: UN PROGETTO NEL PARCO NAZIONALE DELLA SILA. PRIMI RISULTATI E IMPORTANZA DELL’INTERVENTO IN EPOCA COVID-19

The permanence in natural environments and the contact with nature, even in urban areas of proximity (neighbourhood green areas or condominiums), have a relaxing and regenerative power and stimulate the fundamental vital processes. The relationship with open spaces and greenery is an element that promotes personal and collective well-being already in everyday life. This has become even more relevant during the current COVID-19 pandemic crisis, which has significantly changed individual and social life habits, upsetting interpersonal relationships and the relationship with the outside world often experienced from a window. In this context, the Project "Tranquillity Areas Mapping" is inserted in the Sila National Park, of which we report the first results. Carried out in collaboration between CNR-ISAFOM, Department of Agraria of the Mediterranea University of Reggio Calabria, and Sila National Park, the project aims to identify Areas of Tranquillity within the UNESCO Mab Area of the Park, based on the analysis of qualitative and quantitative parameters that characterize them. In its initial stages (September 2019), the project has seen the activation of participatory processes with the involvement of institutions and key local actors. The work presented here deals with the relevance of participation in the planning and management processes of protected natural areas and, in particular, of national parks. The processes under study play an increasingly important role, especially during the COVID-19 emergency, which has accentuated the need to stimulate public interest in natural parks. Increasingly, natural parks are being recognized for their role in providing environmental ecosystem services. Among these, cultural ecosystem services include preserving those "oases of tranquility" more easily accessible to the population of the territories concerned.  A number of participatory experiences carried out during the project are presented. Several convergent approaches were used, making the most of both e-participation and more traditional forms of confrontation (in-depth interviews, focus groups). Finally, the methods used, and the results obtained from work carried out are indicated as potential developments for mapping the quiet areas of the Sila National Park, in view of sustainable management of the latter

Multi-Satellite DVB-RCS System with RCST based on Software Defined Radio

Abstract-Multi-mode satellite terminals are actually the most desired devices on the market, thanks to their flexibility and suitability. A multi-mode radio communication terminal is a terminal allowing two or more transmission mode. In the last few years many research resources have been invested in the study of this new type of terminal. In this work, we define a multi-mode terminal as a terminal capable of communicating both with a Bent-Pipe (BP) satellite and with an On-Board Processor (OBP) satellite and dynamically setting its transmission parameters (e.g. transmission power and code rate). In order to realize this multimode functionality, the most suitable technology is the Software Defined Radio (SDR). The SDR is a set of Hardware and Software technologies that allow one to obtain reconfigurable architectures for network and wireless terminals. The goal of our work is to plan a satellite system based on Digital Video Broadcast with the Return Channel Satellite (DVB-RCS) standard in which the Return Channel Satellite Terminals (RCSTs) are able to adapt it to the channel state, configuring the transmission chain via software, respecting a certain Quality of Service (QoS) constraint on the Packet Error Rate (PER)

Arabs in Europe: arguments for and against integration

The recent wave of immigration across European countries has precipitated an unprecedented political crisis in many Western countries. This is compounded by the fact that the large majority of these migrants originate from Arab countries. Research has demonstrated that Arabs are devalued relative to other socioethnic groups. The present study sought to investigate representations of Arabs and their integration. Twenty-one interviews conducted in Malta were used to analyze the logic and structure of argumentation supporting both favorable and unfavorable positions relative to Arabs. The findings demonstrate a variety of perspectives founded on 6 major themes, namely cultural, sociopolitical, psychological, religious, stigma, and economic issues. All views were elaborated and warranted, and served to justify particular forms of social relations that make the integration of Arabs possible but highly difficult. In particular, findings demonstrate a lack of positive appraisals of Islam. These findings suggest that breaking the spiral of conflict between Europeans and the Arab communities they host requires affirmative action to redress the negative representational climate that Arab immigrants need to negotiate. Our study also introduces an innovative method for unpacking argumentation structures that mark representational fields. This serves to understand the ways by which social representations form and transform in everyday social interaction. This understanding is essential in designing smart policy that can cater to the logic of ordinary citizens

A palladium iodide-catalyzed oxidative aminocarbonylation–heterocyclization approach to functionalized benzimidazoimidazoles

A novel carbonylative approach to the synthesis of functionalized 1H-benzo[d]imidazo[1,2-a]imidazoles is presented. The method consists of the oxidative aminocarbonylation of N-substituted-1-(prop-2-yn-1-yl)-1H-benzo[d]imidazol-2-amines, carried out in the presence of secondary nucleophilic amines, to give the corresponding alkynylamide intermediates, followed by in situ conjugated addition and double-bond isomerization, to give 2-(1-alkyl-1H-benzo[d]imidazo[1,2-a]imidazol-2-yl)acetamides. Products were obtained in good to excellent yields (64–96%) and high turnover numbers (192–288 mol of product per mol of catalyst) under relatively mild conditions (100 °C under 20 atm of a 4:1 mixture of CO–air), using a simple catalytic system, consisting of PdI2 (0.33 mol %) in conjunction with KI (0.33 equiv)

Symbolic universes between present and future of Europe:First results of the map of European societies' cultural milieu

This paper reports the framework, method and main findings of an analysis of cultural milieus in 4 European countries (Estonia, Greece, Italy, and UK). The analysis is based on a questionnaire applied to a sample built through a two-step procedure of post-hoc random selection from a broader dataset based on an online survey. Responses to the questionnaire were subjected to multidimensional analysis–a combination of Multiple Correspondence Analysis and Cluster Analysis. We identified 5 symbolic universes, that correspond to basic, embodied, affect-laden, generalized worldviews. People in this study see the world as either a) an ordered universe; b) a matter of interpersonal bond; c) a caring society; d) consisting of a niche of belongingness; e) a hostile place (others’ world). These symbolic universes were also interpreted as semiotic capital: they reflect the capacity of a place to foster social and civic development. Moreover, the distribution of the symbolic universes, and therefore social and civic engagement, is demonstrated to be variable across the 4 countries in the analysis. Finally, we develop a retrospective reconstruction of the distribution of symbolic universes as well as the interplay between their current state and past, present and future socio-institutional scenarios
