Published: January 2017

Corneal stromal and/or penetrating ocular injuries from pencils and pencil lead are more common in childhood and may lead to intraocular infection or severe intraocular sterile inflammatory reaction. Herein we report 3 children with ocular trauma due to pencil lead injuries. The first case had corneal stromal injury caused by a pencil. In the second case, a pencil perforated the cornea and contacted the iris. In the third case, pencil lead perforated both the cornea and iris and reached the vitreous through the lens zonules. Intracameral triamcinolone (2 mg/0.05 mL) was injected after the pencil lead was removed from the eyeball. Topical anti-inflammatory and cycloplegic drops were prescribed. In conclusion, corneal and especially penetrating ocular injuries from pencil lead may have a good prognosis with the use of appropriate anti-inflammatory and prophylactic antibiotic treatment and follow-up.

: Parkinson's disease (PD) is a neurodegenerative disorder, characterised by cardinal motor features and a multitude of non-motor manifestations. Among them, cognitive impairment in PD has been recognised as a defined clinical entity, and it might lead to an increased risk of developing dementia. Consequently, the present review aimed to ascertain the available interventions for the training of cognitive abilities in persons with PD (PwPD).

Department of Applied Psychology, School of Humanities and Social Sciences, Fuzhou University, University Town, 2 Wulong River North Avenue, Fuzhou, Fujian, 350108, China.

Background: The more rapid adoption of the Internet in education settings has raised concerns about its impact on adolescents who may suffer from cyberbullying victimization. As a negative life experience, cyberbullying victimization can adversely affect adolescents' mental health. Particularly, it can lead to more adolescents developing depression.

The LET enhancement of energy-specific collimation in pencil beam scanning proton therapy.

J Appl Clin Med Phys

January 2025

Department of Radiation Oncology, University of Iowa, Iowa City, Iowa, USA.

Purpose: To computationally characterize the LET distribution during dynamic collimation in PBS and quantify its impact on the resultant dose distribution.

Methods: Monte Carlo simulations using Geant4 were used to model the production of low-energy proton scatter produced in the collimating components of a novel PBS collimator. Custom spectral tallies were created to quantify the energy, track- and dose-averaged LET resulting from individual beamlet and composite fields simulated from a model of the IBA dedicated nozzle system.

. For calculating shielding in x-ray rooms, it is often assumed that the beams impinge perpendicularly on the protective barriers. This is not always true, but this premise simplifies the calculations and enhances protection by being a conservative calculation.
