Structural and Dynamic Heterogeneity of Deep Eutectic Solvents Composed of Choline Chloride and Ortho-Phenol Derivatives.

Structural, thermal, and dynamic properties of four deep eutectic solvents comprising choline chloride paired with phenolic derivative hydrogen-bond donors were probed using experiments and molecular simulations. The hydrogen-bond donors include phenol, catechol, -chlorophenol, and o-cresol, in a 3:1 mixture with the hydrogen-bond acceptor choline chloride. Density, viscosity, and pulsed-field gradient NMR diffusivity measurements were conducted over a range of temperatures.

The case for balloon eustachian tuboplasty in children.

Purpose Of Review: Balloon dilation of the cartilaginous portion of the Eustachian tube has increasingly gained acceptance among otolaryngologists in the treatment of obstructive Eustachian tube dysfunction. There is however little data on the procedure performed in children. The purpose of this study is to review the recent developments regarding balloon dilation in pediatric patients.

High prevalence of syndromic hearing loss in Mexican children undergoing cochlear implantation.

Objective: Studies evaluating genetic sensorineural hearing loss (SNHL) in Hispanic and Latino populations using genomic technologies are lacking. Recent data has shown that Hispanic and Latino children display lower genetic diagnostic rates despite similar prevalence rates of SNHL to their Asian and White counterparts, thus negatively affecting their clinical care. Our objective was to determine the genetic contribution to SNHL in a population of Mexican children undergoing evaluation for cochlear implantation.

Pediatric cerebrospinal fluid rhinorrhea caused by low flow vascular anomaly of the temporal bone: A case series.

Objective: Atraumatic cerebrospinal fluid (CSF) rhinorrhea is uncommon in children and necessitates a multi-disciplinary evaluation for an etiology. Underlying osseous abnormality due to extensive or multifocal low flow vascular anomaly should be considered as a potential cause of spontaneous CSF leak. Treatment of multifocal low flow vascular anomalies may include medical and surgical approaches.
