A European Study of the Performance and Safety of MINIject in Patients With Medically Uncontrolled Open-angle Glaucoma (STAR-II)
2020
Precis In this European study (STAR-II), MINIject, a novel, ab-interno, supraciliary MIGS device, effectively lowered intraocular pressure (IOP) and the need for IOP-lowering medications in patients with primary open-angle glaucoma. Purpose To evaluate the safety and performance of a minimally invasive supraciliary glaucoma drainage device (MINIject DO627, iSTAR Medical SA, Wavre, Belgium) for surgical treatment of primary open angle glaucoma in patients refractory to topical hypotensive medications. Methods In a prospective, interventional, single-arm, multi-center, European study (STAR-II), MINIject was successfully implanted in a standalone procedure in 29 of 31 patients in 8 sites in 3 …
Endoscopic Treatment of Transesophageal Echocardiography-Induced Esophageal Perforation
2018
Perforation of the esophagus is the most severe complication of transesophageal echocardiography (TEE) and can lead to mediastinitis, pleural empyema, or peritonitis. Currently, the majority of patients receive operative treatment with only 6% treated endoscopically. We report our experience with endoscopic and conservative approaches.We retrospectively reviewed all patients treated for esophageal perforation and included all patients with perforation caused by TEE. All patients with perforation of the esophagus by TEE probe underwent conservative or endoscopic treatment, drainage of pleural and mediastinal retentions, and adjusted to antibiotic therapy.From January 2004 to December 2014 a …
Abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar
2006
Aim To discuss a rare, but severe complication arising following routine root canal treatment. Summary An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the or…
Is it really useful the Harmonic scalpel in axillary dissection for locally advanced breast cancer? A case series.
2017
Background. The seroma is one of the most common complications in the axillary lymph nodal dissection (different surgical approaches have been tried to reduce the seroma incidence). In our study we evaluate the outcome of patients using or not the ultrasonic scalpel (Harmonic scalpel) according to a standardized surgical technique. Patients and Methods. From January 2011 to December 2015 120 patients underwent axillary dissection for breast cancer. Patients were divided in two groups: patients belonging to the first group underwent Harmonic scalpel dissection and patients belonging to the second group underwent classical dissection. Each group consisted of 60 patients. Quadrantectomy (QUAD)…
Gestión tradicional de la escorrentía de tormentas para riego de prados en Monteagudo del Castillo (Teruel)
2021
espanolMonteagudo del Castillo (Teruel) esta cerca del polo de maxima tormentosidad violenta de la Peninsula Iberica. El aporte pluviometrico de estas tormentas es capaz de invertir el regimen estacional habitual del clima mediterraneo, con el verano como estacion mas lluviosa. Aqui se estudia la gestion tradicional de la arroyada en dos cuencas del termino municipal, desde la doble perspectiva riesgo/recurso: control de la erosion y aprovechamiento de la arroyada para regar prados. Para gestionar la arroyada concentrada de las tormentas se ha modificado la red de drenaje mediante acequias recolectoras y/o evacuadoras y la rectificacion de la red hidrografica natural. Las acequias de deriva…
Évaluation du colmatage de tranchées d'infiltration selon le type de sol : analyse à long terme
2010
In recent years, limitations linked to traditional urban drainage schemes have been pointed out and new approaches were developed introducing more natural methods for retaining and/or disposing of stormwater. Such practices include infiltration and storage tanks in order to reduce the peak flow and retain part of the polluting components. The impact of such practices on stormwater quantity and quality is not easily assessable because of the complexity of physical and chemical processes involved. In such cases, integrated urban drainage models may play a relevant role providing tools for long term analysis of infiltration structures efficiency. In this study, the effect of the clogging pheno…
Assessment of the SMAP Level-4 Surface and Root-Zone Soil Moisture Product Using In Situ Measurements
2017
International audience; The Soil Moisture Active Passive (SMAP) mission Level-4 Surface and Root-Zone Soil Moisture (L4_SM) data product is generated by assimilating SMAP L-band brightness temperature observations into the NASA Catchment land surface model. The L4_SM product is available from 31 March 2015 to present (within 3 days from real time) and provides 3-hourly, global, 9-km resolution estimates of surface (0-5 cm) and root-zone (0-100 cm) soil moisture and land surface conditions. This study presents an overview of the L4_SM algorithm, validation approach, and product assessment versus in situ measurements. Core validation sites provide spatially averaged surface (root zone) soil m…
A pragmatic approach for downscaling precipitation in alpine-scale complex terrain
2006
A statistical method is presented to downscale precipitation from a mesoscale atmospheric model simulation. The algorithm consists of two steps. First, local subscale variability is estimated based on a high resolution observed climatology. Second, there is a bias correction, which constrains the downscaled model climatology to be equal to the observed climatology on the coarse grid. Combining both steps results in a local scaling factor for each day of the climatological year. The method is applied to the upper Danube catchment which encompasses part of the European Alps and which is characterized by highly complex orography. The subgrid-scale variability described by the first part of the…
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…
Dispositif automatique de caractérisation et de prélèvement des eaux de drainage du site de Virey-le-Grand
2021
National audience; Le drainage a pour objectif d’évacuer rapidement l’excès d’eau de la partie supérieure du sol. Par conséquence il entraine des perturbations dans l’environnement notamment en favorisant la lixiviation d’intrants. Le dispositif de Virey-le-Grand, conçu dans les années 1970 pour étudier les différentes modalités de drainage, a été ré-instrumenté et automatisé afin de travailler sur l’évaluation de l’impact des pratiques agricoles sur la qualité de l’eau. Cette ré-instrumentation associe des équipements robustes comme les augets basculants à de la technologie plus récente telle que les panneaux photovoltaïques et une centrale d’acquisition. L’évolution des technologies a per…
