HRAS mutations define a unique biologic subset of head and neck squamous cell carcinoma. Oncogenic HRAS is uniquely dependent on posttranslational farnesylation for membrane localization and activation of downstream signaling. Tipifarnib, a farnesyltransferase inhibitor, demonstrated encouraging antitumor activity for HRAS mutant head and neck squamous cell carcinoma and modest activity for HRAS mutant salivary gland cancer. New combination strategies to circumvent intrinsic and acquired resistance to TFIs are being investigated.

Objective: We aimed to investigate the effect of adding "rapid decelerations" and "vibrations" during a SemontPLUS maneuver on the dynamics of the inner ear and the success rate of canalolithiasis repositioning.
Methods: We used a previously described upscaled (5×) in vitro model of the posterior semicircular canal of the inner ear to analyze the trajectory of a single and clumped surrogate otolith particle (metallic sphere) during a SemontPLUS maneuver (-60 degrees below earth horizontal) on a repositioning chair (TRV). We compared the angular displacement of these particles with and without the application of "vibrations" or "rapid decelerations" using TRV.

Objectives: This longitudinal experimental study aimed to profile audiometric hearing loss, explore the feasibility and efficacy of low-cost hearing devices, and examine their social and emotional impact on participants in South Sudan, a low-resource humanitarian setting.
Design: We performed pure tone hearing screenings on adults with self-reported hearing disability, randomly providing eligible participants with one of two inexpensive devices-Asana Pro 800, a non-customizable hearing device fit unilaterally, or the Super Ear SE9000, a hand-held amplifier with headphones given one per individual.
Study Sample: Between October 2022 and January 2023, 142 adults underwent hearing screening at the Juba Teaching Hospital ENT clinic, of whom 19 eligible individuals were provided with hearing devices.

Pitch perception affects children's ability to perceive speech, appreciate music, and learn in noisy environments, such as their classrooms. Here, we investigated pitch perception for pure tones as well as resolved and unresolved complex tones with a fundamental frequency of 400 Hz in 8- to 11-year-old children and adults. Pitch perception in children was better for resolved relative to unresolved complex tones, consistent with adults.

Objective: To develop a proof-of-concept smart-phone-based eye-tracking algorithm to assess non-pathologic optokinetic (OKN) nystagmus in healthy participants. Current videonystagmography (VNG) is typically restricted to in-office use, and advances in portable vestibular diagnostics would yield immense public health benefits.
Study Design: Prospective cohort study.
