Service-Learning Through Community-Based Exercise Teaching Enhances Medical Students' Exercise Knowledge, Counseling Confidence, and Habits.

Exercise is a pivotal tool in the prevention and management of chronic disease, a cornerstone of primary care. Yet, there is little formal exercise education in medical school and many medical students feel unprepared to effectively counsel patients about exercise. Since 2019, medical students in the Primary Care Program (PCP), a primary care-focused educational track, at the Keck School of Medicine (KSOM) of the University of Southern California (USC) have taught exercise classes to the local community as part of a service-learning experience.

The human vestibulo-ocular reflex and compensatory saccades in schwannoma patients before and after vestibular nerve section.

Objective: To examine the vestibulo-ocular reflex (VOR) and compensatory-saccades before and after complete unilateral vestibular deafferentation (UVD).

Methods: Forty patients were studied before and after surgery for vestibular or facial schwannoma using the video head-impulse test (vHIT) and multivariable regression.

Results: Prior to UVD (median(IQR), 14(58.

Impact of Cochlear Implantation on Canal and Otolith Function.

Objective: To quantify the impact of cochlear implantation (CI) on all five vestibular end-organs and on subjective ratings of post-CI dizziness.

Methods: Seventy-two patients undergoing unilateral CI were recruited for the study. All participants completed pre- and post-CI three-dimensional video head-impulse tests (3D vHITs) to assess semicircular-canal (SC) function, air- and bone-conducted (AC and BC) cervical and ocular vestibular-evoked myogenic potentials (cVEMPs and oVEMPs) to assess otolith-function and the dizziness handicap inventory (DHI) to measure self-perceived disability.

Naunton's Masking Dilemma Revisited.

Background: Pure-tone audiometry is essential in diagnosing clinical hearing loss. Masking of the nontest ear is mandatory for determining accurate hearing thresholds in the presence of asymmetrical levels between the two ears and for ascertaining the presence of a conductive hearing loss. Paradoxically, over masking occurs when the intensity of the required masking noise to the contralateral ear is such that it exceeds interaural cranial attenuation by an amount sufficient to mask the test ear.

Utility of 3D printed temporal bones in pre-surgical planning for complex BoneBridge cases.

With the advent of single-sided hearing loss increasingly being treated with cochlear implantation, bone conduction implants are reserved for cases of conductive and mixed hearing loss with greater complexity. The BoneBridge (BB, MED-EL, Innsbruck, Austria) is an active fully implantable device with no attenuation of sound energy through soft tissue. However, the floating mass transducer (FMT) part of the device is very bulky, which limits insertion in complicated ears.

Improving sound localization after cochlear implantation and auditory training for the management of single-sided deafness.

Objective: To report a successful case of cochlear implantation and auditory training for the improvement of sound localization in a patient with single-sided deafness.

Study Design: Case report and literature review.

Setting: Tertiary referral otology practice.

Qualitative case studies of five cochlear implant recipients' experience with music.

Cochlear implantation has revolutionized the management of those who suffer from severe-to-profound hearing loss because many patients now achieve excellent speech understanding with objective testing. Nevertheless, speech understanding in noisy conditions and music appreciation remain significant challenges to cochlear implant (CI) users. Music appreciation is an extremely complex experience that is difficult to quantify through a conventional outcome study.

Cochlear implantation in patients with bilateral severe sensorineural hearing loss after major blunt head trauma.

Objective: To highlight issues that impact on cochlear implant candidacy and performance in individuals who have severe bilateral sensorineural hearing loss after major blunt head trauma.

Study Design: Retrospective case review.

Setting: Tertiary level neurotology center.

Medical and noninvasive therapy for Meniere's disease.

Nonoperative therapy continues to be the mainstay of treatment of patients suffering from Meniere disease. Despite extensive research, the exact pathogenesis of Meniere disease remains elusive. The poorly understood nature of this condition has made it nearly impossible to develop treatments that are curative.

Surgical management of Ludwig's angina.

Background: Ludwig's angina (LA) is a dangerous surgical condition that can cause severe airway compromise and death. There is controversy regarding the best way to manage the airway of patients with LA. Options range from conservative management involving close observation and i.
