Le cardiomiopatie nell'infanzia: quadri eziologici ed evolutivi nei primi anni di vita

Premessa: nell’aprile 2006, l’American Heart Association ha approvato la nuova definizione e classificazione delle cardiomiopatie (B. J. Maron e coll. 2006), riconoscendole come un eterogeneo gruppo di malattie associate a disfunzione meccanica e/o elettrica riconducibili ad un ampia variabilità di cause. La distinzione tra le varie forme si basa non più sui processi etiopatogenetici che ne sono alla base, ma sulla modalità di presentazione clinica della malattia. Si distinguono così le forme primarie, a prevalente od esclusivo interessamento cardiaco, dalle forme secondarie in cui la cardiomiopatia rientra nell’ambito di un disordine sistemico dove sono evidenziabili anche disturbi extracardiaci. La nostra attenzione è, nel presente studio, focalizzata sull’analisi delle cardiomiopatie diagnosticate nei primi anni di vita in cui si registra una più alta incidenza di forme secondarie rispetto all’adulto, riservando un particolare riguardo verso quelle forme associate a disordini metabolici. Nello specifico, il nostro obiettivo è quello di sottolineare l’influenza di una diagnosi precoce sull’evoluzione della malattia. Materiali e metodi: abbiamo eseguito uno studio descrittivo in base ad un’analisi retrospettiva di tutti i pazienti giunti all’osservazione del Centro di Cardiologia e Cardiochirurgia Pediatrica e dell’ Età Evolutiva del Policlinico S. Orsola- Malpighi di Bologna, dal 1990 al 2006, con diagnosi di cardiomiopatia riscontrata nei primi due anni di vita. Complessivamente sono stati studiati 40 pazienti di cui 20 con cardiomiopatia ipertrofica, 18 con cardiomiopatia dilatativa e 2 con cardiomiopatia restrittiva con un’età media alla diagnosi di 4,5 mesi (range:0-24 mesi). Per i pazienti descritti a partire dal 2002, 23 in totale, sono state eseguite le seguenti indagini metaboliche: emogasanalisi, dosaggio della carnitina, metabolismo degli acidi grassi liberi (pre e post pasto), aminoacidemia quantitativa (pre e post pasto), acidi organici, mucopolisaccaridi ed oligosaccaridi urinari, acilcarnitine. Gli stessi pazienti sono stati inoltre sottoposti a prelievo bioptico di muscolo scheletrico per l’analisi ultrastrutturale, e per l’analisi dell’attività enzimatica della catena respiratoria mitocondriale. Nella stessa seduta veniva effettuata la biopsia cutanea per l’eventuale valutazione di deficit enzimatici nei fibroblasti. Risultati: l’età media alla diagnosi era di 132 giorni (range: 0-540 giorni) per le cardiomiopatie ipertrofiche, 90 giorni per le dilatative (range: 0-210 giorni) mentre le 2 bambine con cardiomiopatia restrittiva avevano 18 e 24 mesi al momento della diagnosi. Le indagini metaboliche eseguite sui 23 pazienti ci hanno permesso di individuare 5 bambini con malattia metabolica (di cui 2 deficit severi della catena respiratoria mitocondriale, 1 con insufficienza della β- ossidazione per alterazione delle acilcarnitine , 1 con sindrome di Barth e 1 con malattia di Pompe) e un caso di cardiomiopatia dilatativa associata a rachitismo carenziale. Di questi, 4 sono deceduti e uno è stato perduto al follow-up mentre la forma associata a rachitismo ha mostrato un netto miglioramento della funzionalità cardiaca dopo appropriata terapia con vitamina D e calcio. In tutti la malattia era stata diagnosticata entro l’anno di vita. Ciò concorda con gli studi documentati in letteratura che associano le malattie metaboliche ad un esordio precoce e ad una prognosi infausta. Da un punto di vista morfologico, un’evoluzione severa si associava alla forma dilatativa, ed in particolare a quella con aspetto non compaction del ventricolo sinistro, rispetto alla ipertrofica e, tra le ipertrofiche, alle forme con ostruzione all’efflusso ventricolare. Conclusioni: in accordo con quanto riscontrato in letteratura, abbiamo visto come le cardiomiopatie associate a forme secondarie, ed in particolare a disordini metabolici, sono di più frequente riscontro nella prima infanzia rispetto alle età successive e, per questo, l’esordio molto precoce di una cardiomiopatia deve essere sempre sospettata come l’espressione di una malattia sistemica. Abbiamo osservato, inoltre, una stretta correlazione tra l’età del bambino alla diagnosi e l’evoluzione della cardiomiopatia, registrando un peggioramento della prognosi in funzione della precocità della manifestazione clinica. In particolare la diagnosi eseguita in epoca prenatale si associava, nella maggior parte dei casi, ad un’evoluzione severa, comportandosi come una variabile indipendente da altri fattori prognostici. Riteniamo, quindi, opportuno sottoporre tutti i bambini con diagnosi di cardiomiopatia effettuata nei primi anni di vita ad uno screening metabolico completo volto ad individuare quelle forme per le quali sia possibile intraprendere una terapia specifica o, al contrario, escludere disordini che possano controindicare, o meno, l’esecuzione di un trapianto cardiaco qualora se ne presenti la necessità clinica.

La traduzione intralinguistica, interlinguistica e intercodica della trilogia marsigliese di Jean Claude Izzo

Il testo ripercorre le origini del romanzo poliziesco, la sua struttura, le tecniche narrative utilizzate e l’evoluzione del genere che ha condotto alla nascita del Noir francese e del Noir Mediterraneo. Arrivando ad osservare che per le sue caratteristiche, la letteratura noir in generale presenta specificità di tipo culturale, ambientale e linguistico, che risultano molto evidenti nell’opera di Izzo, si giunge a considerare come sia necessario per il traduttore porsi rispetto all’opera come un antropologo o un etnologo, di farsi cioè interprete di una “cultura”. Nella terza parte del lavoro vengono presentati la Trilogia di Izzo, la struttura narrativa e gli elementi socio-culturali presenti nell’opera. La quarta parte propone le teorie relative sia al problema della traduzione interlinguistica, sia a quello della traduzione intralinguistica e successivamente dopo una analisi della traduzione italiana dei testi, presenta, in appendice, una possibile traduzione del prologo di Total Khéops, inteso come sintesi delle caratteristiche narrative e culturali dell’autore. La parte conclusiva di questo lavoro riguarda la traduzione intercodica e, seguendo la linea di pensiero che ha governato l’analisi della Trilogia vengono presi in esame e messi a confronto col testo narrativo alcuni dialoghi significativi dell’adattamento per la televisione.

Creazione e sviluppo di corpora multimediali. Nuove metodologie di ricerca nella traduzione audiovisiva

The construction and use of multimedia corpora has been advocated for a while in the literature as one of the expected future application fields of Corpus Linguistics. This research project represents a pioneering experience aimed at applying a data-driven methodology to the study of the field of AVT, similarly to what has been done in the last few decades in the macro-field of Translation Studies. This research was based on the experience of Forlixt 1, the Forlì Corpus of Screen Translation, developed at the University of Bologna’s Department of Interdisciplinary Studies in Translation, Languages and Culture. As a matter of fact, in order to quantify strategies of linguistic transfer of an AV product, we need to take into consideration not only the linguistic aspect of such a product but all the meaning-making resources deployed in the filmic text. Provided that one major benefit of Forlixt 1 is the combination of audiovisual and textual data, this corpus allows the user to access primary data for scientific investigation, and thus no longer rely on pre-processed material such as traditional annotated transcriptions. Based on this rationale, the first chapter of the thesis sets out to illustrate the state of the art of research in the disciplinary fields involved. The primary objective was to underline the main repercussions on multimedia texts resulting from the interaction of a double support, audio and video, and, accordingly, on procedures, means, and methods adopted in their translation. By drawing on previous research in semiotics and film studies, the relevant codes at work in visual and acoustic channels were outlined. Subsequently, we concentrated on the analysis of the verbal component and on the peculiar characteristics of filmic orality as opposed to spontaneous dialogic production. In the second part, an overview of the main AVT modalities was presented (dubbing, voice-over, interlinguistic and intra-linguistic subtitling, audio-description, etc.) in order to define the different technologies, processes and professional qualifications that this umbrella term presently includes. The second chapter focuses diachronically on various theories’ contribution to the application of Corpus Linguistics’ methods and tools to the field of Translation Studies (i.e. Descriptive Translation Studies, Polysystem Theory). In particular, we discussed how the use of corpora can favourably help reduce the gap existing between qualitative and quantitative approaches. Subsequently, we reviewed the tools traditionally employed by Corpus Linguistics in regard to the construction of traditional “written language” corpora, to assess whether and how they can be adapted to meet the needs of multimedia corpora. In particular, we reviewed existing speech and spoken corpora, as well as multimedia corpora specifically designed to investigate Translation. The third chapter reviews Forlixt 1's main developing steps, from a technical (IT design principles, data query functions) and methodological point of view, by laying down extensive scientific foundations for the annotation methods adopted, which presently encompass categories of pragmatic, sociolinguistic, linguacultural and semiotic nature. Finally, we described the main query tools (free search, guided search, advanced search and combined search) and the main intended uses of the database in a pedagogical perspective. The fourth chapter lists specific compilation criteria retained, as well as statistics of the two sub-corpora, by presenting data broken down by language pair (French-Italian and German-Italian) and genre (cinema’s comedies, television’s soapoperas and crime series). Next, we concentrated on the discussion of the results obtained from the analysis of summary tables reporting the frequency of categories applied to the French-Italian sub-corpus. The detailed observation of the distribution of categories identified in the original and dubbed corpus allowed us to empirically confirm some of the theories put forward in the literature and notably concerning the nature of the filmic text, the dubbing process and Italian dubbed language’s features. This was possible by looking into some of the most problematic aspects, like the rendering of socio-linguistic variation. The corpus equally allowed us to consider so far neglected aspects, such as pragmatic, prosodic, kinetic, facial, and semiotic elements, and their combination. At the end of this first exploration, some specific observations concerning possible macrotranslation trends were made for each type of sub-genre considered (cinematic and TV genre). On the grounds of this first quantitative investigation, the fifth chapter intended to further examine data, by applying ad hoc models of analysis. Given the virtually infinite number of combinations of categories adopted, and of the latter with searchable textual units, three possible qualitative and quantitative methods were designed, each of which was to concentrate on a particular translation dimension of the filmic text. The first one was the cultural dimension, which specifically focused on the rendering of selected cultural references and on the investigation of recurrent translation choices and strategies justified on the basis of the occurrence of specific clusters of categories. The second analysis was conducted on the linguistic dimension by exploring the occurrence of phrasal verbs in the Italian dubbed corpus and by ascertaining the influence on the adoption of related translation strategies of possible semiotic traits, such as gestures and facial expressions. Finally, the main aim of the third study was to verify whether, under which circumstances, and through which modality, graphic and iconic elements were translated into Italian from an original corpus of both German and French films. After having reviewed the main translation techniques at work, an exhaustive account of possible causes for their non-translation was equally provided. By way of conclusion, the discussion of results obtained from the distribution of annotation categories on the French-Italian corpus, as well as the application of specific models of analysis allowed us to underline possible advantages and drawbacks related to the adoption of a corpus-based approach to AVT studies. Even though possible updating and improvement were proposed in order to help solve some of the problems identified, it is argued that the added value of Forlixt 1 lies ultimately in having created a valuable instrument, allowing to carry out empirically-sound contrastive studies that may be usefully replicated on different language pairs and several types of multimedia texts. Furthermore, multimedia corpora can also play a crucial role in L2 and translation teaching, two disciplines in which their use still lacks systematic investigation.

DALLA TERRA DESOLATA ALLA MAPPA DEL NUOVO MONDO: percorso mitografico - letterario sull'influsso di T.S. Eliot nell'ambito della poesia di D. Walcott

Questo progetto intende indagare il rapporto privilegiato che Derek Walcott intesse con gli scrittori che lo hanno preceduto, e in particolare con T.S.Eliot. Attraverso l ‘analisi di un percorso mitografico letterario emerge la rilevanza che per entrambi i poeti assumono sia il paesaggio che il mito. La ricerca svolta si focalizza prevalentemente su The Waste Land di T.S.Eliot e Mappa del Nuovo Mondo di Derek Walcott.

Come città dell'infanzia. Architettura, educazione e immagine in due colonie per i figli degli Italiani all'estero a Cattolica e Tirrenia

The present doctoral dissertation deals with two significant case studies of Italian holiday camps which appear as interesting architectural experiences that reflect both the pedagogic and educational programmes of the fascist regime, and the discussion on the constructive and expressive principles that characterize the Italian architecture during the Thirties. The research explains the colony "XXVIII October for the sons of the Italian workers living abroad", today known as "Le Navi" ("The Ships"), built in Cattolica in 1934 and projected by the Roman architect Clemente Busiri Vici, and the feminine colony "for the sons of the Italian workers living abroad" built in 1934 in Tirrenia and projected by the architects Mario Paniconi and Giulio Pediconi. These holiday camps are the sole buildings commissioned directly by the Department in the Italian Foreign Office with the aim of offering a seaside stay to the sons of the Italians living in the colonies who, probably, could visit Italy only one time in their life. Firstly, the work illustrates the most relevant themes concerning these holiday camps, such as the representative intents that the buildings evoked to the children attending the places. Sun-bathing and group gymnastics were some of the rituals in the communal life, where order and discipline gave a precise internal organization to the spaces. Over the correspondence to practical functions, the figures and the forms of the different spaces of the buildings involve the children in an educational dimension. Subsequently, the function of the Department in the Italian Foreign Office and the planning and constructive ideas of the two colonies will be introduced. These colonies were conceived by a precise social project with educational, welfare and therapeutic aims. The elements, the spaces and the volumes create a fixed and theatrical scene of the life, full of ideological, political and celebratory overtones. Finally, the research shows that the relation between the architectural shape of the buildings and the rituals performed by fascist tutors produces an ideal space, extraneous to the external world that could influence the behavior of the children. The plan is to transmit to the children an image of Italy that will remain engraved in their minds once they have returned to their countries. In these projects there is the intent to transmit the image of "italianity" abroad. The way to do this was to plan for them a scenery which contains all the architectural elements of Italian cities. The holiday camps are proposed a sort of microcosm that appears as an "evocation" of the places and the spaces of Italian cities. The buildings appear as veritable "cities of childhood".
