Hearing Evaluations in Children With Retinoblastoma Treated With Intra-arterial Carboplatin Chemotherapy: A Single Institution Review.

Purpose: To determine whether the administration of intra-arterial carboplatin affected the hearing of children with retinoblastoma.

Methods: Children with retinoblastoma who were treated with intra-arterial carboplatin chemotherapy were included. Hearing tests before chemotherapy including tympanometry, distortion product otoacoustic emissions, and audiogram (if achievable) were performed and repeated 3 to 9 months after concluding intra-arterial therapy.

How Much Time Do Focal Treatments for Retinoblastoma Add to Anesthetic Exposure?

Introduction: Children with retinoblastoma have anesthesia for exams and treatment, but there is little information about how long treatment interventions (laser, cryotherapy, and intravitreal injections) add to routine exams under anesthesia (EUA). This information would be useful for planning operating room schedules, staff schedules, family expectations, and billing.

Methods: A retrospective, single-center, Institutional Review Board (IRB) approved review of anesthesia duration for retinoblastoma children undergoing EUA with laser, cryotherapy, or intravitreal injections performed at MSK between January 2019 and November 2023.

Microscopic self-dynamics in liquid Ne-D_{2} mixtures: Quantum features and itinerant oscillators reexamined.

In this paper, we report the results of a centroid molecular dynamics (CMD) study of the canonical velocity autocorrelation functions (VACFs) in liquid Ne-D_{2} mixtures at a temperature of T=30K and in the full D_{2}-concentration range (0%≤x_{D_{2}}≤100%). This binary system was selected because of its moderate, although sizable, quantum effects which, as far as its equilibrium properties are concerned, are fully described by the path integral Monte Carlo (PIMC) simulations that have been also implemented. A comprehensive test of the VACF spectral moments carried out using three physical quantities (namely, mean kinetic energy, Einstein frequency, and mean-squared force) obtained from PIMC was performed revealing the potentialities, as well as the limitations, of the CMD approach to the single-particle dynamics in these low-T liquid mixtures.

Fingerprints of hydrogen bonding in the terahertz dynamics of ethanol and water: An inelastic x-ray scattering study.

We used inelastic x-ray scattering methods to measure the terahertz spectrum of density fluctuations of ethanol in both liquid and solid phases. The results of a Bayesian inference-based lineshape analysis with a multiple excitation model and the comparison with a previous similar analysis on water indicate that the different structures induced by hydrogen bonds in ethanol and water have a profound influence on the respective dynamic responses, the latter being characterized by longer living and better resolved high-frequency acoustic excitations. In addition, we compare these findings with those obtained with an alternative approach based on the exponential expansion theory and ensuring sum rules fulfillment, demonstrating that the model's choice directly impacts the number of spectral modes detected.
