METHODS: Twenty-nine healthy Malaysian subjects (14 males and 15 females) aged 19 to 30 years participated in this study. After measuring the head circumference, speech-ABR was recorded by using synthesized syllable /da/ from the right ear of each participant. Speech-ABR peaks amplitudes, peaks latencies, and composite onset measures were computed and analyzed.
RESULTS: Significant gender disparities were noted in the transient component but not in the sustained component of speech-ABR. Statistically higher V/A amplitudes and less steeper V/A slopes were found in females. These gender differences were partially affected after controlling for the head size.
CONCLUSIONS: Head size is not the main contributing factor for gender disparities in speech-ABR outcomes. Gender-specific normative data can be useful when recording speech-ABR for clinical purposes.
METHODS: This study involved 307 adults aged 60 years and older. Participants had their hearing and cognition measured using pure tone audiometry and Mini Mental State Examination (MMSE), respectively.
RESULTS: Pure tone average (low) accounted for significant but minimal amount of variance in measure of MMSE. Multiple regression analyses were also performed on normal and impaired hearing cohorts and cohorts with younger (60-69 years) and older (≥70 years) groups. The results revealed a significant relationship between PTA (low) and MMSE only in the younger age group. In contrast, no significant relationship was found between PTA (high) and cognition in any of the cohorts.
CONCLUSION: Pure tone average (low) is significantly but minimally related to measure of general cognitive status. Similar relationship is not observed between high-frequency hearing and cognition. Further research using a more comprehensive cognitive test battery is needed to confirm the lack of association between high-frequency hearing and cognition.
METHODS: A total of 301 older adults (⩾60 years of age) participating in a study on aging had their hearing tested using pure-tone audiometry. Self-perceived hearing loss was assessed using a single question. Sociodemographic profile, otologic history, and general cognitive status were also obtained.
RESULTS: A single question had low sensitivity in detecting actual hearing loss: 31.3% for 4-frequency average > 25 dBHL and 48.8% for 4-frequency average > 40 dBHL. Besides hearing level, history of otorrhea and tinnitus were factors that were associated with self-perceived hearing loss among older adults with at least mild hearing loss. Hearing-help-seeking behavior was not associated with any of the tested variables. The hearing aid adoption rate was 2.7% and 7.3% among participants with 4-frequency averages > 25 dBHL and > 40 dBHL, respectively.
CONCLUSION: The underestimation of hearing loss in the majority of older adults in this study poses a potential barrier to hearing loss intervention.
METHODS: All patients who underwent EEN for advanced rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah. We reported the 5-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors.
RESULTS: Twelve patients with rNPC (2 rT3 and 10 rT4) were followed-up over a mean duration of 44.8 months (range, 40-440 weeks). The 5-year OS was 50.0% (mean 44.75 months), DFS was 25.0% (mean 35.25 months) and the DSS was 58.3% (mean 43.33 months). No severe operative complications were encountered and no independent prognostic factors for survival outcome were identified.
CONCLUSION: This is the first report in English that exclusively described the long-term 5-year survival data in patients with both rT3 and rT4 recurrent NPC after EEN. The data suggest that EEN is a feasible treatment to improve survival with minimal morbidities in patients with rT3 and rT4 recurrent NPC. However, more studies with larger patient size is recommended.
