RESUMO
Introduction: To develop and validate a click-based mobile "Audiclick" app employing click noises for hearing assessments. Materials and Methods: This prospective comparative study compares the "AudiClick" app as a hearing screening tool to pure tone audiometry. Participants listened to sounds through wired earbud headphones that were connected to an Android or iOS device. Results: The study involved 110 participants aged between 18 to 80 years old. All degrees of hearing loss severity corresponds to pure tone average (p < 0.01) results. The app was also found to be effective at identifying hearing loss (80-99% sensitivity, specificity, positive predictive value, and accuracy). Test-retest reliability had also shown excellent ICC scores of 0.93. Conclusions: This study demonstrates that a mobile app using click sounds can be as efficient as pure tone audiometry for field screenings, while being more cost-effective and easier to develop.
RESUMO
Background: Endoscopic nasal surgery is often a tedious process due to repeated removal of the Hopkins rod telescope from the nasal cavity for manual defogging of the tip due to the presence of blood, smoke, and secretions. Objective: To design and print a 3-dimensional (3D) low-cost telescopic sleeve to allow the defogging solution to clean the rigid telescope tip without removing it from the nasal cavity. In addition, the sleeve must also act as a conduit for suction and irrigation to provide a clear surgical field view intraoperatively. Results and conclusion: A 3D printed low-cost telescopic sleeve, when used in conjunction with other add-ons, can be a helpful and cost-effective adjunct during endoscopic nasal surgery.

RESUMO
@#Introduction: To correlate the score obtained using a bilingual (Malay and English) 14 points questionnaire in the detection of hearing loss at the University of Malaya, Medical Centre (UMMC), Kuala Lumpur, Malaysia over a 9 month period. Methods: This is a prospective instrument correlation study done on 93 children aged 1-4 years of age with speech and language delay for at least 3 months. Hearing status was confirmed using otoacoustic emissions, pure tone audiometry and brainstem evoked response (BSER). Hearing status was then compared to the 14-point questionnaire final scores and is statistically correlated. Results: There were 26 patients, 15 males (58%) and 11(42%) females who were diagnosed to have hearing loss. The average age of presentation was 2.49 and conductive hearing loss accounted for about 74% of cases of hearing loss. The mean questionnaire score obtained through our patients was 3.83±1.987. Discriminant analysis suggests that a questionnaire score of above 4 was indicative that the child was suffering from hearing loss. Conclusion: Our study suggests that the low-cost bilingual (Malay and English) questionnaire can be used to detect hearing loss in the Malaysian population and could potentially be useful in rural health centres to help detect hearing loss and to determine the urgency of referral to a tertiary health centre.
