Otoneurological management of petrous apex cholesterol granuloma
2009
Objective: The aim of the study is to review the management of petrous apex cholesterol granuloma. The surgical approaches for drainage or total removal and the wait and see policy were analyzed, and outcomes were evaluated. Methods: Retrospective charts of 27 patients managed for petrous apex cholesterol granuloma with a minimum follow-up of 12 months were analyzed in a quartenary skull base center. Presenting symptoms and signs were recorded, and radiologic imaging was evaluated. Management options included wait and see policy and surgery by several approaches. Results: The mean age of patients affected by the lesion was 38.8 years. The mean follow-up was 56.7 months. Patients complained …
Estimation of the time lag occurring between vegetation indices and aridity indices in a Sicilian semi-arid catchment
2009
The evolution of drought phenomena in a Sicilian semi-arid catchment has been analyzed processing both remote sensing images and climatic data for the period 1985-2000. The remote sensing dataset includes Landsat TM and ETM+ multispectral images, while the climatic dataset includes monthly rainfall and air temperature. The results have been specifically discussed for areas where it is possible to neglect agricultural activities and vegetation growth is only influenced by natural forcing. The main outcome of this study is the quantification of the time lag between the remote sensing retrieved vegetation indices and the aridity indices (AIs) calculated from climatic data. Moreover the obtaine…
A Systematic Review of the Hydrological, Environmental and Durability Performance of Permeable Pavement Systems
2021
Due to urbanization, large portions of vegetated territory have been replaced by waterproof surfaces. The consequences are greater outflows, lower infiltration, and lower evapotranspiration. Pavement systems made with permeable surfaces allow the infiltration of water, ensuring reduction of runoff volume. In this paper, the methods of analysis of the hydrological and environmental performance of the pavement systems are reviewed in the context of urban drainage and regarding their durability. The purpose is to present an overview of the studies published during the last decade in the field. The Pubmed and Web Science Core Collection electronic databases were used to conduct the scientific l…
Verkostonäkökulma ennallistamiskohteiden valinnassa
2013
Verkostonäkökulma korostuu vahvasti luonnonsuojelun suunnittelussa Suomessa ja maailmalla. Suojelualueita ei voi nähdä yksittäisinä eristyneinä alueina, vaan luonnonsuojelualueiden verkosto ja koko ympäröivä maisema ylläpitävät yhdessä tietyn alueen eliölajistoa. Parhaiden alueiden kytkeytyvyyden varmistamista ja verkostojen ylläpitämistä on myös ehdotettu ratkaisuksi biodiversiteetin säilyttämiselle, kun ilmastonmuutos pakottaa lajeja siirtymään uusille asuinalueille. Verkostonäkökulma kannattaa huomioida myös ennallistamiskohteiden valinnassa – mikä ei kuitenkaan ole yksiselitteistä ja helppoa. nonPeerReviewed
Drainage of a Mediastinal Cyst by Endobronchial Ultrasound-Guided Needle Aspiration

Management of Pneumothoraces Detected on Chest Computed Tomography: Can Anatomical Location Identify Patients Who Can Be Managed Expectantly?
2014
Abstract Background Pneumothorax (PTX) can be readily detected by computed tomography (CT) or ultrasound. However, management of PTX in hemodynamically stable patients remains controversial. Study Objectives We sought to investigate whether a distinct anatomical distribution of PTX along prespecified chest zones as detected by CT can be described in patients with or without subsequent chest tube thoracotomy (CTT), thus potentially allowing the extended focused assessment with sonography for trauma (EFAST) ultrasound examination to guide PTX management. Methods We performed a retrospective review of chest CT scans performed in the emergency department (ED) of a Level I trauma center. CT scan…
Histopathologic Findings in Early Encapsulated Blebs of Young Patients Treated With the Ahmed Glaucoma Valve
2010
Objective/aim Uncontrolled glaucoma presents a challenge for the ophthalmic surgeon especially in children and juvenile patients. For many patients who have undergone failed surgical procedures before, episcleral implants remain the last choice. Encapsulated blebs forming over antiglaucoma devices present a complication leading to malfunctioning or even failure with reincrease in intraocular pressure. We report our histopathologic findings of such blebs developing around the Ahmed glaucoma valve (AGV) after a short time period in young patients. Materials and methods Nine young patients (2 to 17 y of age) with otherwise uncontrollable glaucoma were treated with AGV (models FP-7 and FP-8, si…
Ecohydrological modelling of flow duration curve in Mediterranean river basins
2013
Abstract Flow duration curve provides an important synthesis of the relevant hydrological processes occurring at the basin scale, and, although it is typically obtained from field observations, different theoretical approaches finalized to its indirect reconstruction have been developed in recent years. In this study a recent ecohydrological model for the probabilistic characterization of base flows is tested through its application to a study catchment located in southern Italy, where long historical series of daily streamflow are available. The model, coupling soil moisture balance with a simplified scheme of the hydrological response of the basin, provides the daily flow duration curve. …
Decadal oscillations of the aquatic chemistry of river waters in Latvia
2018
Abstract. Water quality changes of surface waters can be used to assess human impact intensity, but of importance is to consider also impacts of climate change/variability and naturally occurring changes of environmental quality. In Latvia, during the recent decades a major reduction of anthropogenic pressure has happened due to restructuring of economy and industrial production, resulting in major decrease of loading of many groups of pollutants. However, trends and driving factors for other groups of substances have not been much studied. Long term (1980–2012) results of hydrochemical monitoring, performed in rivers of Latvia, are analysed during this study in connection with long-term se…
Laudun-L'Ardoise (30), Avenue du Général de Gaulle
2021
Le diagnostic de l’avenue du Général de Gaulle se situe au sud-est du village actuel de Laudun. Malgré un environnement archéologique relativement riche, cette intervention n’aura livré, sur les 16 000 m² testés, qu’une fosse de l’âge du Bronze, témoin le plus méridional de l’occupation identifiée sous le lotissement de l’Oppidum, deux fossés encadrant peut-être un chemin antique et une fosse récente contenant les restes d’un équidé. Au nord, la présence marquée de mobiliers antiques dans les sédiments de surface du lotissement de l’Oppidum laissait présager une occupation de cette période à proximité, qui n’a pas été confirmée sur l’emprise de ce nouveau diagnostic. Si elle existe, elle po…
