Media Device Use and Vision Disorders in the Pediatric Age: The State of the Art.

Introduction: Evidence is consistent with increased screen viewing time among children and adolescents, and anticipation at the age at which children interact with media devices. Incorrect use of technology, as well as overuse, may lead to serious consequences. This study aims to revise scientific international literature and to describe the potential eye risks correlated to screen viewing time in the pediatric age.

Iopamidol Abatement from Waters: A Rigorous Approach to Determine Physicochemical Parameters Needed to Scale Up from Batch to Continuous Operation.

The abatement of iopamidol (IPM), an X-ray iodinated contrast agent, in aqueous solution using powdered activated carbon (PAC) as a sorbent was investigated in the present work. The material was characterized by various analytical techniques such as thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller analysis, dynamic light scattering, and zeta potential measurements. Both thermodynamic and kinetic experiments were conducted in a batch apparatus, and the effects of the initial concentration of IPM, the temperature, and the adsorbent bulk density on the adsorption kinetics were investigated.

Tailoring Synthetic Pelargonic Acid Esters for Bio-Based Lubricant Applications: Exploring the Relationship between Structure and Properties.

Pelargonic acid (PA) is commercially obtained by oxidative cleavage of fatty acid double bonds. Its esters are interesting compounds used to create bio-based products. An industrially relevant application of these compounds is in the field of solvent manufacturing and formulation of green lubricating oils.

Ibuprofen Adsorption on Activated Carbon: Thermodynamic and Kinetic Investigation via the Adsorption Dynamic Intraparticle Model (ADIM).

The adsorption efficiency of commercial activated carbon toward ibuprofen (IBU) was investigated and described using the adsorption dynamic intraparticle model (ADIM). Although the adsorption capacity of activated carbon has been widely studied, the kinetic models used in the literature are simplified, treating adsorption kinetics with pseudo-kinetic approaches. In this paper, a realistic model is proposed, quantitatively describing the influence of the main operation parameters on the adsorption kinetics and thermodynamics.

Optical coherence tomography angiography in Tuberous sclerosis complicated with macular choroidal neovascularization.

This study describe the optical coherence tomography angiography (OCTA) features of a young patient with Tuberous sclerosis complicated with CNV unilateral macular choroidal neovascularization during the ranibizumab therapy. OCTA scans of macular region of right eye, revealed a dense microvascular network confirming the diagnosis of CNV. After four monthly intravitreal injections, OCTA revealed a decrease of size and activity of CNV.

Optical Coherence Tomography Angiography in Children with Leber-Coats Disease.

Introduction: The aim of this work was to describe the optical coherence tomography (OCT) angiography (OCTA) features in paediatric Leber-Coats disease.

Methods: Three children presenting with unilateral, clinically active Leber-Coats disease were evaluated using spectral domain OCT and OCTA. OCT angiograms were analysed and compared with the current literature.

The challenging management of pediatric corneal transplantation: an overview of surgical and clinical experiences.

Purpose: Pediatric keratoplasty is an immense challenge because of the technical complexity of the procedure and the high risk of rejection in young graft recipients. Our aim is to describe the major indications and appropriate timing of corneal transplantation intervention, including a report of our experience and surgical tips, in conjunction with the current literature.

Methods: Review of the literature on indications for keratoplasty in pediatric patients classified as: congenital, traumatic and acquired non-traumatic opacities.

Anterior ischemic optical neuropathy in children on chronic peritoneal dialysis: report of 7 cases.

Background: Anterior ischemic optic neuropathy (AION) is characterized by infarction of the optic nerve head due to hypoperfusion of the posterior ciliary arteries and causes sudden blindness in adults on chronic dialysis, but has rarely been described in children. Unlike adults, children do not have comorbidities related to aging.

Methods: We retrospectively analyzed data of 7 children on nocturnal continuous cycling peritoneal dialysis (CCPD) who developed AION identified within the Italian Registry of Pediatric Chronic Dialysis.

Photodynamic therapy in von Hippel-Lindau disease in children.

Von Hippel-Lindau disease is characterized by retinal hemangiomas that often produce hemorrhages and retinal detachment. A 10-year-old boy with von Hippel-Lindau disease presenting with telangiectasias, endophytic angiomas, and exudative retinal detachment underwent treatment with retrobulbar steroid injection, laser photocoagulation, and photodynamic therapy, which led to improvement of visual acuity.
