Sudden and Asymmetric Hearing Loss Among Active Duty Service Members: Underscoring the Importance of Active Screening.

Military personnel are at increased risk of asymmetric hearing loss secondary to noise exposure. This report illustrates the importance of expeditiously evaluating for retrocochlear pathology even in young active duty service members with asymmetric or sudden hearing loss. A 36-year-old male presented with right-sided sudden hearing loss and dizziness. Audiometry revealed profound mid-to-high-frequency sensorineural hearing loss in the right ear. A 10-day course of oral steroid therapy and two intratympanic steroid injections were unsuccessful in restoring hearing. MRI revealed a 4.2 cm contrast-enhancing cerebellopontine angle tumor, consistent with a vestibular schwannoma (VS). Microsurgical resection utilizing a retrosigmoid craniotomy approach was performed with near-total resection of the tumor and preservation of the facial nerve but not the cochlear nerve. Despite preservation of the facial nerve, progression of post-operative facial weakness required gold weight placement to prevent exposure keratopathy. The patient had recovered partial function in all facial nerve branches at last follow-up. In light of the rising global incidence of VS, any asymmetric or sudden hearing loss in military service members should be evaluated with audiometry and referral to otolaryngology for workup of retrocochlear pathology.

A Dizzying Complaint: Investigating the Intended Meaning of Dizziness Among Patients and Providers.

OBJECTIVE/HYPOTHESIS: To assess for semantic differences regarding the definition of dizziness among otolaryngology patients, otolaryngologists, and non-otolaryngologist providers. STUDY DESIGN: Cross-sectional survey. METHODS: Between March and May 2020, a survey consisting of 20 common descriptors for dizziness within five domains (lightheadedness, motion sensitivity, imbalance, vision complaints, and pain) was completed by patients at two outpatient otolaryngology clinics. Surveys were subsequently obtained from otolaryngology and non-otolaryngology providers attending a multidisciplinary dizziness lecture. The primary outcome measure was to assess for differences in definition of dizziness between patients and providers. Secondary outcome measures included assessing differences between otolaryngologists and non-otolaryngologists. RESULTS: About 221 patients and 100 providers participated. Patients selected a median of 7 terms compared to 8 for providers (P = .375), although providers had a larger overall distribution of number of terms selected (P = .038). Patients were more likely than providers to define dizziness according to the following domains: lightheadedness (difference 15.0%; 95% confidence interval [CI] 5.5%-25.3%), vision complaints (difference 21.6%, 95% CI 12.0%-29.6%), and pain (difference 11.5%, 95% CI 4.7%-17.1%). Providers were more likely to define dizziness according to the motion sensitivity domain (difference 13.8%, 95% CI 6.8%-19.6%). Otolaryngology and non-otolaryngology providers defined dizziness similarly across symptom domains. CONCLUSION: Although patients and providers both view dizziness as imbalance, patients more commonly describe dizziness in the context of lightheadedness, vision complaints, and pain, whereas providers more frequently define dizziness according to motion sensitivity. These semantic differences create an additional barrier to effective patient-provider communication. LEVEL OF EVIDENCE: 4. Laryngoscope, 131:E1443-E1449, 2021.

Cochlear Implantation in the Active Duty Military Population: A Survey Assessing Military Readiness and Satisfaction.

OBJECTIVE: Evaluate the impact of cochlear implantation (CI) on retention for United States active duty (AD) service members. STUDY DESIGN: Retrospective observational study. SETTING: Tertiary military CI centers. PATIENTS: AD service members who underwent CI and completed a telephonic survey. MAIN OUTCOME MEASURES: The ability for military personnel to maintain AD status following CI as determined by the nonvolitional hearing-related AD separation rate and whether subjects would recommend CI to other qualified candidates. RESULTS: Twenty AD service members who underwent CI between 2004 and 2020 completed a telephonic survey. Fifteen (75%) were single-sided deafness (SSD) and five were traditional CI candidates. The mean age was 40.3 years (range 27.5-64.3), 19 (95%) were male, and 12 (80%) were Caucasian. Ten (50%) were officers and 14 (70%) were noncombat support personnel. Idiopathic sudden sensorineural hearing loss was the most common cause of hearing loss (8, 40%) followed by occupational noise exposure (4, 20%). Sixteen (80%) maintained AD status yielding 46.15 person-years of AD service following CI. For SSD, 14 (93%) maintained AD status yielding 40.54 person-years of AD service. The nonvolitional hearing-related patient separation rate for CI recipients with bilateral hearing loss was 35.65 cases per 100 AD person-years and 0 cases per 100 person-years for SSD candidates. Nineteen (95%) stated they would recommend CI to other AD CI candidates. CONCLUSIONS: The vast majority of AD CI recipients, and particularly those with SSD, are able to remain on AD after surgery and report a high degree of satisfaction with their implant.

Experiential Learning Cycles as an Effective Means for Teaching Psychiatric Clinical Skills via Repeated Simulation in the Psychiatry Clerkship.

OBJECTIVE: This retrospective study compares differences in clinical performance on the psychiatry clerkship Objective Structured Clinical Examination (OSCE) between students receiving traditional repeated clinical simulation with those receiving repeated clinical simulation using the Kolb Cycle. METHODS: Psychiatry clerkship OSCE scores from 321 students who completed their psychiatry clerkship in 2016 and 2017 were compared. Specific performance measures included communication skills as determined by the Essential Elements of Communication, gathering a history, documenting a history and mental status exam, defending a differential diagnosis, and proposing a treatment plan. Results were calculated using repeated two-way analysis of variance between students receiving no simulation and traditional repeated simulation training (TRS) as compared to students receiving no simulation and repeated simulation utilizing the Kolb cycle (KRS). RESULTS: Students who received KRS performed significantly better in three of the five components of the clerkship OSCE as compared to students who received TRS. Specifically, students who received KRS performed better on gathering a history (+ 14.1%, p < 0.001), documenting a history (+ 13.4%, p < 0.001), and developing a treatment plan (+ 16.7%, p < 0.001). There were no significant differences in communication skills or in developing and defending a differential diagnosis. CONCLUSIONS: Psychiatry clerkship students engaged in repeated simulations explicitly integrated with the Kolb cycle demonstrate improved clinical skills as measured by OSCE performance. Integration of the Kolb cycle in designing simulation experiences should be carefully considered and may serve as a model for individualized coaching in programs of assessment.
