The impact of cochlear implantation on speech and language outcomes in children with asymmetric sensorineural hearing loss.

Introduction: Cochlear implantation (CI) is considered in children with asymmetric sensorineural hearing loss (ASHL), or severe to profound sensorineural hearing loss in one ear, and better hearing contralaterally. The benefits of a CI in these children are not well established. This study investigated the impact of unilateral CI on speech and language outcomes in pediatric patients with ASHL.

Risk Factors Associated With Postoperative Delirium in Patients Undergoing Head and Neck Free Flap Reconstruction.

Importance: Postoperative delirium (POD) is associated with an increased rate of adverse events, higher health care costs, and longer hospital stays. At present, limited data are available regarding the risk factors for developing POD in patients undergoing head and neck free flap reconstruction. Identification of patients at high risk of developing POD will allow implementation of risk-mitigation strategies.

Extramedullary hematopoiesis of the sphenoid sinus associated with hereditary spherocytosis: A case report.

Extramedullary hematopoiesis is a rare cause of a sinonasal mass that presents unique diagnostic and treatment challenges. While there are numerous reports of patients with hereditary spherocytosis developing extramedullary hematopoiesis in the posterior mediastinum, involvement in the paranasal sinuses has not previously been described. Here, we present the first case of a patient with hereditary spherocytosis developing extramedullary hematopoiesis in the sphenoid sinus.

Anterior Skull Base Reconstruction: Does Fat Preparation Matter?

 This article aims (1) to determine whether there is any difference in cerebrospinal fluid (CSF) leak rate after anterior skull base autologous fat reconstruction based on how the fat is prepared, and (2) to measure impact on surgical times by reconstruction type.  Translational animal model surgical technique 3-arm trial, comparing two different methods of autologous fat skull base reconstruction versus a nonreconstructed control group.  Animal study.

Mice perceive synergistic umami mixtures as tasting sweet.

Previous electrophysiological investigation shows that combinations of compounds classified by humans as umami-tasting, such as glutamate salts and 5'-ribonucleotides, elicit synergistic responses in neurons throughout the rodent taste system and produce a pattern that resembles responses to sweet compounds. The current study tested the hypothesis that a synergistic mixture of monopotassium glutamate (MPG) and inositol monophosphate (IMP) possesses perceptual similarity to sucrose in mice. We estimated behavioral similarity among these tastants and the individual umami compounds using a series of conditioned taste aversion (CTA) tests, a procedure that measures whether a CTA formed to one stimulus generalizes to another.
