Dottore, mio figlio non impara a leggere”. I Disturbi Specifici dell’Apprendimento (DSA) e il pediatra di famiglia

2015

Si parla di Disturbo Specifico di Apprendimento (DSA) quando sono presenti delle difficoltà isolate e circoscritte nella lettura (Dislessia) e/o nella scrittura (Disortografia) e/o nel calcolo (Discalculia) nonostante la presenza di adeguate capacità cognitive e opportunità scolastiche. Tali difficoltà hanno carattere evolutivo e persistente, presentandosi con diversa espressività clinica nelle varie fasi dello sviluppo. La prevalenza mondiale del disturbo si attesta tra il 5 e il 15% (DSM 5, 2013). L’incidenza è maggiore nei maschi, con un rapporto M/F stimato intorno a 2:1, 3:1 (DSM 5, 2013). In Italia la stima di prevalenza dei DSA fra i bambini in età scolare oscilla fra il 3 e il 5% (C…

Electrochemical incineration of organic pollutants: effect of the nature of the pollutants and of the temperature

2009

The electrochemical oxidation of some organic pollutants, including three carboxylic acids (oxalic, formic and maleic), at boron doped diamond (BDD) and DSA anodes, using galvanostatic alimentation, was investigated in order to study the effect of the temperature and of the nature of the pollutants on the process. In incineration electrolyses, the performances of the process in terms of carboxylic acid conversion and current efficiency dramatically depend on the adopted operative conditions. The abatement of the organic pollutant depends on the nature of the carboxylic acid. Quite interestingly, the opposite effect of the nature of the substrate on the performances of the process was observ…

Electrochemical oxidation of organics at metal oxide electrodes: The incineration of oxalic acid at IrO2-Ta2O5 (DSA-O2) anode

2008

Abstract The electrochemical incineration of oxalic acid (OA) at Ti/IrO2–Ta2O5 (DSA-O2) anode was investigated to find the influence of the operative parameters on the performances of the process. Polarization curves and chronoamperometric measurements indicate the probable occurrence of a direct electrochemical oxidation of OA at the surface of the DSA anode. In incineration electrolyses, the performances of the process in terms of OA conversion and current efficiency dramatically depend on the adopted operative conditions. Interestingly, very high OA removal and current efficiency were obtained when the process was performed at relatively high temperatures (50 °C) or in the presence of Na…

The Mediterranean Coast of Andalusia (Spain): Medium-Term Evolution and Impacts of Coastal Structures

2019

This paper shows coastal evolution along the Andalusia Region (Spain) and the impacts on it of coastal structures. The study area was divided into 47 units to calculate the erosion/accretion/stability (or evolution) rates by using the DSAS extension of ArcGIS software. Evolution rates were divided into different classes from &ldquo

La enseñanza del inglés como lengua extranjera en alumnos con dislexia evolutiva

2017

Las dificultades de aprendizaje, entre las que se encuentran la dislexia, el Trastorno Generalizado del Desarrollo (TGD), el Trastorno por Déficit de Atención (TDA) con o sin hiperactividad, etc., han sido estudiadas y atendidas con especial esmero por una amplia gama de profesionales dentro del mundo de las especialidades de neurología, psiquiatría, neuropsicología, psicología y psicopedagogía, durante los últimos 20 años. A pesar de ello la dislexia sigue siendo un territorio lleno de controversias, ya que no hay un consenso interdisciplinario y esta falta de acuerdo hace que sea una fuente de confusión y desorientación para padres y docentes. Esto ha contribuido a complicar la relación f…

Bilateral Ultrathin Descemet’s Stripping Automated Endothelial Keratoplasty vs. Bilateral Penetrating Keratoplasty in Fuchs’ Dystrophy: Corneal Highe…

2021

Background and Objectives: The objective of this paper is to compare the visual outcomes and quality of life (QoL) after bilateral ultrathin Descemet’s stripping automated endothelial keratoplasty (UT-DSAEK) with bilateral penetrating keratoplasty (PK) for Fuchs’ endothelial dystrophy (FED). Materials and Methods: Retrospective comparative cohort study, including 11 patients with FED who underwent bilateral PK and 13 patients with FED who underwent bilateral UT-DSAEK. All patients were already pseudophakic or had undergone a combined cataract procedure. The main outcomes were corrected distance visual acuity (CDVA) corneal higher-order aberrations (HOAs), contrast sensitivity (CS) and quali…
