Objective: PerClot is a biocompatible, polysaccharide haemostatic system recommended for surgical procedures. It is an absorbable modified polymer that is non-pyrogenic and is derived from purified plant starch. Our goal was to evaluate the safety, efficacy and usefulness of PerClot in head and neck surgery (H&N) in our department.
Methods: All patients who received PerClot after their neck operation over 1-year period (2019-2020) were prospectively investigated. The information collected included demographics, admission and discharge dates, type of operation, operative details, postoperative complications and their management. The data were collected and analysed using Excel.
Results: A total of 57 patients (males = 26, females = 31) with mean age of 51 (range 19-83) were identified. None of the patients developed primary or secondary haemorrhage. Ten patients suffered from post-operative wound complications (18%). Wound infection was noticed in 9/57 (16%) of patients. 1/57 patients had seroma.
Conclusions: PerClot is safe, effective in reducing the postoperative bleeding and would appear to be useful in head and neck surgery with minimal adverse effects.

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.
