OBJECTIVE: To determine the prevalence rate of follow-up among infants who had a "refer" result on initial newborn hearing screening and to identify reasons for default by parents or guardians.
METHODS:
Design: Cross-Sectional Study
Setting: Tertiary National University Hospital
Participants: 79 parents or guardians whose newborns obtained a "refer" result on initial hearing screening were interviewed over the phone.
RESULTS: Among those babies who had a "refer" result on initial hearing screening, 51% followed up for repeat testing. The most common reasons for non-follow up by parents or guardians include being busy, distance from the hospital and baby's health condition.
CONCLUSIONS: The follow-up rate in this study is higher compared to previous figures (27%), but is still below target. The reasons for non-follow-up obtained suggest problems may exist on all levels of the healthcare system. Appropriate solutions to address these problems should be explored.

Literature has reported the existence of cholesteatoma in chronic suppurative otitis media with tuberculosis. This report demonstrates that a cholesteatoma can be associated with an acute otitis media with tuberculosis. The importance of a high index of suspicion for tuberculous otitis media and its consequent meticulous management including diagnostic tests, medical and surgical procedures and monitoring are discussed.

Objective: To compare outcomes of COVID-19 positive and COVID-19 negative patients who underwent tracheostomy for prolonged intubation in terms of weaning duration, length of ICU and hospital stay, overall and 30-day mortality, and explore risk factors for particular outcomes (mortality, 30-day mortality and weaning duration post tracheostomy). Methods: Design: Retrospective Cohort Study Setting: Tertiary National University Hospital Participants: Of 122 adult patients that underwent tracheotomy between March 30, 2020 and March 30, 2021; 76 adult patients underwent tracheostomy for prolonged intubation were analyzed. Results: Open tracheotomy was performed on 122 adult patients. Seventy six (62.3%) due to prolonged intubation and 46 (37.7%) for airway prophylaxis. Among the former, the mean age was 58.46±16.81 and 54 (71.05%) patients were female, 22 (28.95%) tested COVID-19 positive and 54 (71.05%) tested negative. Mean APACHE II score was 16.62±6.78. Average days of intubation prior to tracheostomy was 29.14±17.66 days. No statistically significant difference in outcomes (weaning days, length of stay, days discharge from ICU and hospital, 30-day mortality, days to death) were noted between COVID19 positive and negative patients who underwent tracheostomy for prolonged intubation. Mortality rates post tracheostomy in this institution appear to be higher than existing literature. On multiple linear regression analysis, days of intubation prior to tracheostomy was associated with increased weaning time post-tracheostomy (OR: 0.35 CI:0.18-0.51 95% p = <.001). This implies that for every additional day of intubation prior to tracheostomy, weaning days increase by 0.35 of a day. Conclusion Outcomes of COVID-19 compared to non-COVID-19 patients undergoing tracheostomy for prolonged intubation do not seem to be significantly different which is consistent with existing literature.

Objectives: We present in this article the design and evaluation of a blended learning approach for training community healthcare providers in performing newborn hearing screening (NHS). Methods: We developed a blended learning course for training community healthcare providers on eHealth-enabled NHS, following Bloom’s revised taxonomy of educational objectives. The training involved three components: computer-based training (CBT), face-to-face (FTF) training, and on-site coaching. We used surveys and post-training interviews following Level 1 Kirkpatrick’s training evaluation model to get initial feedback on the training program. Results: Thirty-one community healthcare providers from five rural health units and a private hearing screening center, with a mean age of 42.2 ± 12.0 years, participated in the pilot. 93.5% of the participants agreed that the program content met stated objectives and was relevant to their practice. The length of the course was perceived to be adequate. Overall satisfaction with the program was rated at 8.5 ± 0.9 (with ten as the highest). The majority expressed that the CBT and FTF course were satisfactory at 93.5% and 100%, respectively. All participants agreed that the course enhanced their knowledge of newborn hearing screening and telehealth. Positive reviews were received from participants on the use of CBT to improve theoretical knowledge before FTF training. Participants declared that FTF training and on-site coaching helped improved NHS skills and implementation. Conclusion Competent community healthcare providers are critical to strengthening the performance of the health system, and advances in the education and technology sectors offer promising potential in upskilling local healthcare providers. The increasing access of Filipino healthcare providers to improved information and communications technology (ICT) is a significant catalyst for pedagogical innovation, like the use of blended learning in the continuous professional development of health practitioners. As ICTs gradually penetrate the health sector, the challenge we now face is not whether but how we can use innovations in education strategies to benefit healthcare providers.

Objective. The current paper aimed to discuss developing the online newborn hearing screening certification course and revisions made from pre-pandemic face-to-face strategies to the online implementation in response to COVID-19 limitations. Furthermore, it aimed to create recommendations for the refinement of the course.

Methods. The development of the adaptation consisted of document review, focus group discussions among program faculty before and after implementation, which covered the demand for the certification course, opportunities for adaptation, situational limitations, and online implementation advantages and concerns. In addition, a cost-benefit analysis of the online course was done.

Results. The certification course was developed within a month and retained the same learning objectives going into an online implementation. One significant change was the addition of a local experience module which allowed for the participation of regional newborn hearing screening coordinators. More resources were required from both instructors and learners to implement successfully. Due to the asynchronous nature of the online course, the evaluation scheme was adapted accordingly. However, teaching strategies were limited. The pricing of the course was also not optimal.

Conclusion. Although there were merits in adapting the certification course to the online learning platform, there were areas for refinement. These were the alignment of all course modules to learning objectives, the addition of varied teaching methods, and the revision of pricing for the course.

Objective: Newborn hearing screening (NHS) in the Philippines has been mandated by law since 2009. However, lack of awareness and knowledge about NHS remains a challenge, especially among healthcare providers. This paper describes the pilot implementation of a computer-based training (CBT) course on NHS and teleaudiology among primary healthcare providers (PHCPs) in rural Philippines. Methods: A four-module web-based training course on newborn hearing screening and teleaudiology in an online learning management system (LMS) was field-tested among PHCPs from eight rural communities in the Philippines. Participants were given four weeks to complete the course. Results: Forty-two PHCPs participated in the CBT. Thirty-four (81%) completed the whole course (mean attrition rate of 4.8% per module) at a mean duration of 10.2 days. Baseline data shows that participants had no NHS training, although the majority (83%) had information and communications technology (ICT) training. Comparison of preand post-test mean scores showed a 24.0% (p<0.001) significant increase in the post-test in all four modules. Passing rates (i.e., score ≥70%) from pre- to post-test increased by 54.6% (range: 38-80% increase). Usability of the CBT was rated high with a mean score of 4.32 out of 5 (range: 4.13 to 4.47), covering all eight parameters. Participants expressed general satisfaction and a positive attitude on CBT to improve knowledge on NHS and teleaudiology. Conclusion Even in low resource settings where gaps in ICT infrastructure exist, eLearning can be used as an alternative approach to increase awareness and support training of healthcare providers on newborn hearing screening.

Objectives: To determine the initial clinical diagnoses of patients with tuberculous otitis media (TBOM), to determine the value of PCR test, biopsy, and ancillary diagnostic procedures in detecting middle ear TB infection, and to establish the differences in treatment outcomes. Methods: The clinical records of twenty-eight patients identified with middle ear TB infection by PCR test and biopsy, from January 2010 to December 2016, were reviewed to determine their initial clinical diagnoses. The positivity rates of PCR test and biopsy were compared. The records of 12 patients included in a previous publication were revisited and included in the present study population. The combined cases were classified according to clinical diagnosis to constitute a summary of demographic characteristics, clinical diagnoses, laboratory tests, and treatment outcomes. Results of diagnostic and surgical procedures were reviewed and analyzed. Clinical findings and hearing test results before and after treatment were compared. Results: Of the 28 patients, eight different clinical diagnoses of patients confirmed with middle ear TB were determined. PCR test diagnosed most cases belonging to the early and chronic stages of the disease process. Biopsy diagnosed mostly the chronic cases but failed to diagnose acute cases and late cases with diagnosis of chronic suppurative otitis media with cholesteatoma. By including the twelve cases that were published in 2011, the range of clinical diagnoses was expanded and an outcome of eleven clinical diagnoses confirmed with TB infection was established. Analysis of treatment outcomes showed that the clinical and hearing outcomes were better for patients managed at the early stage of the disease than for those presenting at the late stages of the disease process who underwent more complicated surgical procedures. Conclusion Our study supports the concept of tuberculous otitis media (TBOM) clinical spectrum, implying a paradigm shift in the established thinking that TBOM presents only as a chronic disease. The combined use of PCR and biopsy is a potential diagnostic tool to improve case detection rate, further broaden the scope of the clinical spectrum, and develop better control and preventive strategies for TBOM.

Objective: Recent advances in epigenetic studies continue to reveal novel mechanisms of gene regulation and control, however little is known on the role of epigenetics in sensorineural hearing loss (SNHL) in humans. We aimed to investigate the methylation patterns of two regions, one in RB1 and another in GJB2 in Filipino patients with SNHL compared to hearing control individuals. Methods: We investigated an RB1 promoter region that was previously identified as differentially methylated in children with SNHL and lead exposure. Additionally, we investigated a sequence in an enhancer-like region within GJB2 that contains four CpGs in close proximity. Bisulfite conversion was performed on salivary DNA samples from 15 children with SNHL and 45 unrelated ethnically-matched individuals. We then performed methylation-specific real-time PCR analysis (qMSP) using TaqMan® probes to determine percentage methylation of the two regions. Results: Using qMSP, both our cases and controls had zero methylation at the targeted GJB2 and RB1 regions. Conclusion Our study showed no changes in methylation at the selected CpG regions in RB1 and GJB2 in the two comparison groups with or without SNHL. This may be due to a lack of environmental exposures to these target regions. Other epigenetic marks may be present around these regions as well as those of other HL-associated genes.
