CARTOGRAFIA E NUOVI ORIENTAMENTI DELLE POLITICHE DEL TURISMO IN SARDEGNA

Il lavoro analizza il rapporto tra la cartografia redatta in occasione della predisposizione del Piano Paesaggistico Regionale (PPR) e le recenti politiche del turismo. Viene posto in evidenza il ruolo che la cartografia tematica assume nella nuova gestione del territorio con particolare riferimento alla valorizzazione e tutela del paesaggio e dell’ambiente.The work analyzes the connection between the cartography made on the occasion of Regional landscape plan (PPR) and the recent tourism policy. It is pointed out the role that the thematic cartography plays in the new territory management with a particular reference to the enhancement and protection of the landscape and of the environment

CARTOGRAPHY, TOPOGRAPHY, LANDSCAPES

Il paesaggio gode oggi di una grande attenzione non solo sotto il profilo scientifico ma anche dal punto di vista politico e culturale, tanto da renderlo protagonista delle più recenti politiche territoriali. Con il presente lavoro si intende analizzare il contributo che la cartografia topografica può fornire per la redazione degli strumenti di pianificazione e gestione del territorio tenendo conto dell’esigenza di conservare, valorizzare e recuperare i paesaggi, proponendo alcune riflessioni, basate sulla redazione di piani a valenza paesaggistica, maturate in Sardegna.The landscape is today in a great deal of attention not only from the scientific point of view but also politically and culturally, so as to make it the protagonist of the most recent territorial policies. The present paper seeks to analyze the contribution of topographic maps for the preparation of planning instruments and land management, taking into account the need to conserve, enhance and recover landscapes, offering a few thoughts, based on the drafting of plans valued landscapes, work out in Sardinia

WATERWAYS, PREFERRED TOPIC WITHIN CΑRΤΟGRΑΡΗΥ ΟF ΙΤΑLΙΑΝ ΕΧΡLΟRΕRS IN EAST AFRICA: AMONG PROPOSALS, DEBATES, ΑΝD ΙΝFΟRΜΑΤΙΟΝ

Vengono analizzate le cartografie redatte dagli esploratori italiani dell'Africa Orientale e il loro contributo alla conoscenza geografica delle regioni attraversate dai fiumi Giuba e Uebi Scebeli. Dopo aver esaminato anche il contesto geo-politico del momento storico nel quale si sono svolte le esplorazioni, una particolare attenzione viene riservata al simbolismo del tema «acqua» e all'impatto che la scoperta dell'«altrove» ha avuto negli esploratori.The aim of this work is to analyze the cartographies drew up by Italian explorers in East Africa and their contribution to the geographical knowledge of the regions crossed by the Rivers Giuba and Uebi Scebell. After analyzing the Geopolitical context of the historical period where the explorations took place, a special attention is addressed to the symbolism of «water» and to the way the discovery and the representation of the «elsewhere» impacted on previous knowledge of explorers

Vocación turística dos itinerarios relixiosos e perspectivas de desenvolvemento territorial: o Camiño de Santu Jacu en Sardeña (Italia)

Desde hace años asistimos al descubrimiento de itinerarios culturales y religiosos, considerados instrumentos capaces de favorecer el desarrollo local sostenible. Su valor es principalmente turístico, y en Italia existen numerosas iniciativas. El presente trabajo se centra en las efectuadas por la Región de Cerdeña para la estructuración de productos e itinerarios orientados al mercado del turismo religioso. A partir del análisis de la literatura científica, se subraya la potencialidad turística de las rutas religiosas, prestando especial atención al Camino de Santu Jacu, que atraviesa toda la región. El método y los instrumentos deinvestigación son los de la geografía económica, que contempla el recurso a indicadores estadísticos y a los Sistemas de Información Geográfica (SIG). Mediante las elaboraciones realizadas, el trabajo destaca cómo los caminos religiosos pueden contribuir a aumentar la competitividad regional si reciben apoyo y promoción a partir de acciones específicas y políticas de desarrollo local.For some years we have been witnessing the rediscovery of cultural and religious itineraries, considered tools capable of promoting sustainable local development. Their value is mainly touristic and there are numerous initiatives in Italy aimed at the religious and slow tourism market. Starting from the analysis of scientific literature, the contribution highlights the tourist potential of religious routes with a focus on the Santu Jacu Way, which crosses the entire island. The method and tools are those of economic geography, which contemplate the use of statistical indicators and Geographic Information Systems (GIS). Through the elaborations carried out, the paper highlights how religious paths can contribute to increasing regional competitiveness if supported and promoted within specific local development actions and policies. Desde hai anos asistimos ao descubrimento de itinerarios culturais e relixiosos, considerados instrumentos capaces de favorecer o desenvolvemento local sustentable.

The usefulness of 99mTc-SestaMIBI scan in the diagnostic evaluation of thyroid nodules with oncocytic cytology

OBJECTIVE: To assess the relevance of (99m)Tc-SestaMIBI (MIBI) scan in the diagnostic evaluation of thyroid nodules with oncocytic cytology. SUBJECTS AND METHODS: Twenty-four patients with a single (or prevalent) 'cold' solid nodule with Hurthle cells (HC) at fine needle aspiration cytology (FNAC) were studied. Cytological diagnosis of oncocytic metaplasia (OM) or HC tumor (HCT) was made when HC on the smear were comprised 10-75%, or >75%. Nodules concentrating MIBI at early and late (2 h after washout) stages were considered MIBI-positive. In all cases histological findings were obtained after total thyroidectomy. RESULTS: FNAC was malignant or suspect for malignancy in 16 cases (six HCT and 10 OM) and not suspect in eight (two HCT and six OM). Histological examination revealed 14 malignant tumors (11 HCT and three OM), and 10 benign thyroid lesions (three HCT and seven OM). Sensitivity of FNAC for malignancy was 92.8% and specificity was 70.0%; HCT were identified by FNAC in only 35.7% and OM in 70.0% of cases. No significant difference in MIBI positivity was found between malignant and benign thyroid nodules. The highest percentage of MIBI positivity was found in HCT (78.5%), but MIBI-positive nodules were also observed in thyroid lesions with HC metaplasia (40.0%). CONCLUSIONS: MIBI scintiscan has no value in differentiating malignant from benign HC thyroid neoplasias. Most HCT are MIBI-positive, but this scan is not sufficiently specific to differentiate true HC neoplasias from other thyroid lesions showing HC at FNAC, although an MIBI-negative scan strongly supports the absence of true HCT

Rhabdoid tumor of the thyroid gland: a variant of anaplastic carcinoma

Rhabdoid tumor of the thyroid gland is a very rare neoplasm, characterized by significant metastatic potential. All of the 6 cases reported in the recent literature had poor outcomes. We report an additional case involving, to our knowledge, the oldest patient reported so far. A 67-yearold woman had a nodular goiter for all of her adult life and presented with a rapidly growing mass in the right lobe. Histologic examination showed a highly cellular neoplasm with a solid infiltrative growth pattern. Extracapsular invasion was evident. Rhabdoid cells were large, with abundant cytoplasm, eosinophilic inclusions, and eccentric nuclei containing distinct nucleoli. Immunohistochemistry identified vimentin, sarcomeric actin, myoglobin, and cytokeratin expression in the tumor cells; they were negative for desmin, thyroglobulin, and calcitonin. Scattered follicles with nuclear features of papillary thyroid carcinoma were detected; these cells were immunoreactive for thyroglobulin and TTF-1. Reverse transcriptase polymerase chain reaction using specific primers for RET/PTC1 and RET/PTC3 fusion genes identified a RET/PTC3 gene rearrangement in the rhabdoid tumor. Despite radiotherapy, the neoplasm rapidly progressed, with massive local and mediastinal metastasis leading to death 5 months after presentation. The hypothesis that rhabdoid tumor is a variant of anaplastic thyroid carcinoma is supported by the identification of a RET/PTC gene rearrangement, a feature of carcinomas of follicular cell derivation
