One-stage laparoscopic procedure for a patient with bilateral colorectal tumours and renal carcinoma

We describe a case of a patient with synchronous bilateral colorectal tumours and renal carcinoma who underwent one-stage laparoscopic surgery procedure with right transperitoneal nefrectomy, right hemicolectomy and sigmoidectomy. One-stage laparoscopic procedure can be used safely and successfully for a patient with multiple primary tumours.

Technique and outcomes about a new laparoscopic procedure: the Pelvic Organ Prolapse Suspension (POPS)

Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simplier than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology.

Laparoscopic-endoscopic rendez-vous resection of iuxta-cardial gastric GIST

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and they often require a surgical removal. Gastrointestinal stromal tumors can originate from any part of the gastrointestinal tract but gastric location is the most common. In the past the risk of rupture of pseudocapsula and peritoneal dissemination have discouraged surgeons from making a minimally invasive surgical treatment. Recently laparoscopic wedge resection has been proposed. Performance of this mini-invasive technique is however difficult in some gastric location of gastrointestinal stromal tumors, such as iuxta-cardial region. The Authors report and discuss a new technique they used to remove a gastrointestinal stromal tumor located just below the cardia, using a rendez-vous endoscopic and laparoscopic technique.

Giant cell tumor of tendon sheath: study of 64 cases and review of literature

The giant cell tumor of tendon sheath (GCTTS) is the most common benign neoplasm in the hand after the ganglion cyst. Several hypotheses were formulated about the etiological factors of these tumors, but still there is not a common opinion on etiology, prognostic factors and recurrence rate. This article presents a review of literature of the last 15 years about GCTTS to assess the demographic, clinical and histological profile. We compared the information obtained from literature with our experience of 64 cases between 2000 and 2012. Our study showed similar results to those reported in literature, except for the recurrence rate: only 3 cases (4.7%) of 64 patients reported recurrence (versus about 15% on average in literature). Among the various possible factors that predispose to recurrence, it is necessary that the surgeon ensures complete excision of the tumor and removal of any residual satellite nodules. Although the marginal excision is the treatment of choice, it is often difficult to perform due to for the location and the strict adherence of the tumor to the tendon or neurovascular bundles. We used in all cases a magnifying loupe to help a careful research of satellite lesions and to respect surrounding structures.

Green Infrastructure and climate change adaptation

One of the main challenges urban areas, and more particularly the compact ones, are facing is their adaptation to climate change. In recent years, is had been recognized that a more ecosystem approach to spatial planning can play a critical role in meeting these challenges. Green Infrastructure (GI) and its integration in spatial planning emerges as one of the most appropriate and effective ways to improve microclimate and tackle the impacts of climate change and mainly the Urban Heat Island (UHI) effect. This paper initially attempts to clarify the term GI and portrays its benefits and its role as an important spatial planning tool to fulfill different environmental, social and economic needs of urban areas. Then, the paper proceeds to an empirical evaluation of the role of GI in reducing the vulnerability to UHI effect in a compact urban area of the city of Thessaloniki. For this reason, a simple methodology is developed with a twofold purpose: to recognize the risks posed by climate change and especially UHI and to assess the potential offered by available in a compact area GI assets as well as by their redesign in order to maximize their contribution to climate change adaptation.

"Natural" disasters as (neo-liberal) opportunity? Discussing post-hurricane Katrina urban regeneration in New Orleans

By providing a wide literature review, post-hurricane Katrina uneven urban regeneration in New Orleans is presented here by framing it within a historical perspective in order to underline how environmental threats too often seem to be not so much “natural” but rather man-made as well as to highlight both the reasons and the ways in which, in post-disaster reconstruction, competitive growth has been valued over equity, by directly benefiting those who were already the most advantaged. The aim is to highlight how environmental disasters can be considered as socially constructed phenomena, as they cannot be seen as a single event but rather as a process made by a series of progressive steps occurring within different spheres, which do not necessarily concern the environment only.

Cities at risk: status of Italian planning system in reducing seismic and hydrological risks

Italy and its urban systems are under high seismic and hydrogeological risks. The awareness about the role of human activities in the genesis of disasters is achieved in the scientific debate, as well as the role of urban and regional planning in reducing risks. The paper reviews the state of Italian major cities referred to hydrogeological and seismic risk by: 1) extrapolating data and maps about seismic hazard and landslide risk concerning cities with more than 50.000 inhabitants and metropolitan contexts, and 2) outlining how risk reduction is framed in Italian planning system (at national and regional levels). The analyses of available data and the review of the normative framework highlight the existing gaps in addressing risk reduction: nevertheless a wide knowledge about natural risks afflicting Italian territory and an articulated regulatory framework, the available data about risks are not exhaustive, and risk reduction policies and multidisciplinary pro-active approaches are only partially fostered and applied.

Surface thermal analysis of North Brabant cities and neighbourhoods during heat waves

The urban heat island effect is often associated with large metropolises. However, in the Netherlands even small cities will be affected by the phenomenon in the future (Hove et al., 2011), due to the dispersed or mosaic urbanisation patterns in particularly the southern part of the country: the province of North Brabant. This study analyses the average night time land surface temperature (LST) of 21 North-Brabant urban areas through 22 satellite images retrieved by Modis 11A1 during the 2006 heat wave and uses Landsat 5 Thematic Mapper to map albedo and normalized difference temperature index (NDVI) values. Albedo, NDVI and imperviousness are found to play the most relevant role in the increase of nighttime LST. The surface cover cluster analysis of these three parameters reveals that the 12 “urban living environment” categories used in the region of North Brabant can actually be reduced to 7 categories, which simplifies the design guidelines to improve the surface thermal behaviour of the different neighbourhoods thus reducing the Urban Heat Island (UHI) effect in existing medium size cities and future developments adjacent to those cities.

Aspects of Land Take in the Metropolitan Area of Naples

Land take is a phenomenon of great concern nowadays because of the large number of its negative impacts regarding biological, economic and social balance. In Italy, the development of urban and other artificial land has been irreversibly transforming a nonrenewable resource such as soil, regardless the almost constant population rate, with different speed depending of the region considered. The aim of this paper is to analyze the phenomenon in the metropolitan area of Naples, which is an area highly affected by territorial aggression of human matrix. The data used are both by the Institute for Environmental Protection and Research (ISPRA) Report 2015 on the usage of the land and by ISTAT relating to the resident population up to the 1st of January 2015 and the extension of land for agricultural use (Census 2010). The mathematical combination of this data creates a new indicator that can be referred to as “residual land”; this residual area is of great extension with many different characteristics and it could represent the area where the phenomenon of land take most occurs. The identification, measurement and analysis of “residual land” provide new insights on the evolution of land take and this new indicator can represent a critical element to work on to prevent future land transformation and protect natural and agricultural areas within the Italian context.

Reviews pages: Extreme weather events caused by climate change

Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always remaining in the groove of rigorous scientific in-depth analysis. During the last two years a particular attention has been paid on the Smart Cities theme and on the different meanings that come with it. The last section of the journal is formed by the Review Pages. They have different aims: to inform on the problems, trends and evolutionary processes; to investigate on the paths by highlighting the advanced relationships among apparently distant disciplinary fields; to explore the interaction’s areas, experiences and potential applications; to underline interactions, disciplinary developments but also, if present, defeats and setbacks. Inside the journal the Review Pages have the task of stimulating as much as possible the circulation of ideas and the discovery of new points of view. For this reason the section is founded on a series of basic’s references, required for the identification of new and more advanced interactions. These references are the research, the planning acts, the actions and the applications, analysed and investigated both for their ability to give a systematic response to questions concerning the urban and territorial planning, and for their attention to aspects such as the environmental sustainability and the innovation in the practices. For this purpose the Review Pages are formed by five sections (Web Resources; Books; Laws; Urban Practices; News and Events), each of which examines a specific aspect of the broader information storage of interest for TeMA.

Sicily in Transition Research Project. Investigations at Castronovo di Sicilia. Results and Prospects, 2015

Il progetto Sicily in Transition è nato dalla collaborazione delle Università di York e di Roma Tor Vergata, con il pieno ap-poggio della Soprintendenza ai BB. CC. AA di Palermo. La finalità della nostra ricerca è quella di analizzare, attraverso il registro archeologico, in quale modo i mutamenti di regime politico hanno influenzato organizzazione, composizione e stili di vita delle popolazioni soggette. L’arco di tempo considerato va dal VI al XIII secolo, periodo nel quale la Sicilia ha visto diverse dominazioni: quella bizantina, islamica, normanna e sveva. Sicily in Transition prevede di analizzare con metodi in parte nuovi, in parte più tradizionali, sia insiemi di reperti (ecofatti e manufatti) prodotti da precedenti scavi, sia di acquisire dati attraverso nuove indagini. In particolare gli scriventi hanno scelto di indagare un’area molto promettente della Sicilia centrale: il territorio di Castronovo di Sicilia. Qui, in due campagne di ricerca durate ciascuna quattro settimane, sono state realizzate indagini magnetometriche, ricognizioni di superficie, di archeologia dell’architettura e sondaggi stratigrafici. La finalità era quella di valutare il potenziale archeologico dei principali siti storici del territorio. I primi risultati sono promettenti in relazione alla varietà tipologica e cronologica dei diversi insediamenti identificati: una fortezza dei secoli VII-IX sul Monte Kassar; un fortilizio con fasi del pieno medioevo e dell’età moderna sul Colle San Vitale; un ampio villaggio non difeso con fasi dall’età tardoantica al medioevo, incluse importanti testimonianze di età islamica, nell’area del Casale San Pietro. Le indagini preliminari hanno quindi confermato le ampie potenzialità informative dell’intero territorio di Castronovo rispetto ai temi della nostra ricerca e stanno quindi consentendo di programmare gli interventi futuri.

Novana, its territory and the Pisa South Picenum Survey Project II

Si presenta in questa sede una sintesi dei risultati emersi dalle campagne 2014-2015 del Pisa South Picenum Survey Project II, relativo alle alte valli dei fiumi Aso e Tenna, nelle Marche meridionali. Dalle ricognizioni intensive effettuate nel territorio comunale di Amandola (Provincia di FM) è emerso un fitto popolamento rurale costituito da piccole fattorie, databili a partire dalla fine del III sec.a.C., e posizionate all’interno di una griglia centuriale. Questo territorio, con tutta probabilità viritim adsignatus a seguito della lex de agro Gallico et Piceno viritim dividundo del 232 a.C., doveva avvalersi di un polo di aggregazione sociale e amministrativa ubicato nelle vicinanze e ben collegato alla viabilità principale. La posizione strategica, un’accurata analisi dell’assetto centuriale e numerosi rinvenimenti archeologici permettono di identificare questa praefectura nell’area dell’attuale Comunanza dove possiamo localizzare l’antica Novana citata da Plinio (N.H., III, 11)., un centro piceno che divenne, forse, un foro, e poi una praefectura ed infine un municipium.

Applicazione di un veloce metodo di estrazione del DNA per l’identificazione di prodotti ittici marini.

L'identificazione dei prodotti ittici è uno dei temi chiave in materia di sicurezza alimentare. L’errata etichettatura dei prodotti alimentari e la sostituzione di alcuni ingredienti rappresentano questioni emergenti in termini di qualità e sicurezza alimentare e nutrizionale. L'autenticazione e la tracciabilità dei prodotti alimentari, gli studi di tassonomia e di genetica di popolazione, così come l'analisi delle abitudini alimentari degli animali e la selezione delle prede, si basano su analisi genetiche tra cui la metodica molecolare del DNA barcoding, che consiste nell’amplificazione e nel sequenziamento di una specifica regione del gene mitocondriale chiamata COI. Questa tecnica biomolecolare è utilizzata per fronteggiare la richiesta di determinazione specifica e/o la reale provenienza dei prodotti commercializzati, nonché per smascherare errori di etichettatura e sostituzioni fraudolente, difficile da rilevare soprattutto nei prodotti ittici trasformati. Sul mercato sono disponibili differenti kit per l'estrazione del DNA da campioni freschi e conservati; l’impiego dei kit, aumenta drasticamente il costo dei progetti di caratterizzazione e di genotipizzazione dei campioni da analizzare. In questo scenario è stato messo a punto un metodo veloce di estrazione del DNA. Esso non prevede nessuna fase di purificazione per i prodotti ittici freschi e trasformati e si presta a qualsiasi analisi che preveda l’utilizzo della tecnica PCR. Il protocollo consente l'amplificazione efficiente del DNA da qualsiasi scarto industriale proveniente dalla lavorazione del pesce, indipendentemente dal metodo di conservazione del campione. L’applicazione di questo metodo di estrazione del DNA, combinato al successo e alla robustezza della amplificazione PCR (secondo protocollo barcode) ha permesso di ottenere, in tempi brevissimi e con costi minimi, il sequenziamento del DNA.
