PMID: 16156907

The objective of this prospective study was to report on the prevalence of hearing impairment in the neonatal unit population. From 15 February 2000 to 15 March 2000 and from 15 February 2001 to 15 May 2001, 401 neonates were screened using transient evoked otoacoustic emissions (TEOAE) followed by second-stage screening of those infants who failed the initial test. Eight (2 per cent) infants failed one ear and 23 (5.74 per cent) infants failed both ears, adding up to 7.74 per cent planned for second-stage screening. Five out of 22 infants who came for the follow up failed the screening, resulting in a prevalence of hearing impairment of 1 per cent (95 per cent confidence interval [95% CI]: 0.0-2.0). Craniofacial malformations, very low birth weight, ototoxic medication, stigmata/syndromes associated with hearing loss and hyperbilirubinaemia at the level of exchange tranfusion were identified to be independent significant risk factors for hearing impairment, while poor Apgar scores and mechanical ventilation of more than five days were not. In conclusion, hearing screening in high-risk neonates revealed a total of 1 per cent with hearing loss. The changes in the risk profile indicate improved perinatal handling in a neonatal population at risk for hearing disorders.

Primary thyroid lymphoma (PTL) is a rare form of thyroid cancer that is known to be associated with Hashimoto thyroiditis. This association is supported by the presence of elevated titres of both antithyroglobulin and antimicrosomal antibodies in up to 95 percent of patients with PTL. Most patients with PTL present with a rapidly enlarging neck mass and compressive symptoms. The majority of thyroid cancer patients have normal levels of thyroid hormones; they are rarely hyperthyroid, with no obvious clinical features of thyrotoxicosis. We describe a patient who presented with minimal clinical features of thyrotoxicosis despite having markedly elevated serum free thyroxine and suppressed serum thyroid-stimulating hormone levels.

Introduction: Responder’s action during mass environmental chemical incident involves collaboration of multiple agency. They clean the exposure site, control public safety and safe lives. The health of the responder is also as valuable as the public and always been neglected. Hence, this study is to highlights the method used and challenges during the incidents. Methods: A modified Occupational Health Surveillance Programme designed by Baker and Matte (Thirteen Steps in designing and implementing an Occupational Health Surveillance Programme) was imple-mented. These method full fill the criteria of impossible further reduce exposure to known hazards and uncertain health effect of the offending chemicals. Two core workplace namely the source of chemical contamination locale and victims’ evacuation centre were identified. The exposed responder is identified and categorised according to their expected exposure. Offending chemicals identified were known hazardous to health. An electronic survey form was developed and the surveillance were conducted during the event and post-exposures of one, third and sixth months. Laboratory tests were performed as a grab sample randomly and strategically to represent responder exposure. Results: During the event, 1338 responders were surveyed and twenty percent had symptoms of cough, headache, sore throat, nausea and skin irritation. After one-month post-exposure, three percent of responder noted to have continue symptoms. Laboratory tests were performed randomly due to the sheer numbers of responders in action. Only sixty-one samples were collected and sixteen percent had positive metabolites for urine cyanide. Re-sponders with abnormal laboratory result (FBC/LFT/RP/Urine) were interviewed and a repeat sample were performed. Conclusion: The health surveillance of the responder in mass environmental chemical incident is a great challenge when the exposure level is unsure and involve more than one chemicals. Likewise, reliability and validity adopting statistical test for health surveillance instruments is unattainable due to urgency. However, a proper method of occu-pational surveillance need to be devised and implemented to ensure the protection of worker’s health is guaranteed.
Supraglottic Schwannoma: Dilemma and Challenges in Management

Laryngeal schwannomas are rare lesions that represent less than 1.5% of all benign laryngeal tumors. Its slow and submucosal growth may cause a delay in consultation and management. Herein, a case of right supraglottic schwannoma is diagnosed in a 34-year-old lady who was unconcerned about hoarseness for 10 years. She was referred to otorhinolaryngology clinic for assessment when hoarseness was detected during consultation for a gynecology surgery. Apart from hoarseness, there were no noisy breathing, shortness of breath or aspiration symptoms. Flexible nasopharyngolaryngoscopy showed a submucosal bulge at the right vestibular fold obscuring the vocal fold causing an airway concern. Computer tomography scan of the neck revealed a heterogenous enhancing mass centered at the right supraglottis measuring 2.6 × 2.7 × 2.7 cm. There were no erosions of the adjacent thyroid and arytenoid cartilages. Subsequently, complete excision of the lesion was done endoscopically. Definitive diagnosis of schwannoma was obtained via histopathology examination. This paper presents our approach and operative steps in the excision of this lesion using microlaryngoscopy with cold instruments.

AIM: An aging population is a potential burden for unprepared developing countries. Malaysia is foreseen to be an aging country by 2035. Thus, this study aimed to determine the prevalence and factors associated with hearing disability among older persons in Malaysia.
METHODS: Data from a nationwide survey implemented using a stratified cluster sampling design were analyzed. This study was carried out through face-to-face interviews and guided questionnaires. The questions were based on the Washington Group of Disability (WG) questionnaires, which produce multiple disability identifiers. Hearing disability is defined as at least one domain or question out of four questions coded as "A lot of difficulty" or "Cannot hear at all".
RESULTS: The prevalence of hearing disability among older persons aged ≥60 years was 6.4% (95% CI 5.0-8.3), whereas 1.5% (95% CI 0.90, 2.50) older persons were reported to be using a hearing aid. The determinants of hearing disability are being male (aOR 2.67, 95% CI 1.94-3.66), being unemployed (retired, homemaker, unemployed; aOR 1.86, 95% CI 1.86-4.14) and had no formal education (aOR 18.25, 95% CI 4.18-79.55).
CONCLUSIONS: Promoting healthy aging is important and crucial for Malaysia, in preparation toward an aging nation, as it could reduce the country's financial burden in the long term. Health-related agencies should promote health awareness and treatment centers in relation to hearing disability among older persons, as they should be educated and informed about healthcare choices availability, which is aligned with the Global Disability Action Plan 2014-2021.

Fulltext Self-reported symptom study of COVID-19 chemosensory dysfunction in Malaysia

Alterations in the three chemosensory modalities-smell, taste, and chemesthesis-have been implicated in Coronavirus Disease 2019 (COVID-19), yet emerging data suggest a wide geographic and ethnic variation in the prevalence of these symptoms. Studies on chemosensory disorders in COVID-19 have predominantly focused on Caucasian populations whereas Asians remain understudied. We conducted a nationwide, multicentre cross-sectional study using an online questionnaire on a cohort of RT-PCR-confirmed adult COVID-19 patients in Malaysia between 6 June and 30 November 2020. The aim of our study was to investigate their presenting symptoms and assess their chemosensory function using self-ratings of perceived smell, taste, chemesthesis, and nasal blockage. In this cohort of 498 patients, 41.4% reported smell and/or taste loss when diagnosed with COVID-19, which was the commonest symptom. Blocked nose, loss of appetite, and gastrointestinal disturbances were independent predictors of smell and/or taste loss on multivariate analysis. Self-ratings of chemosensory function revealed a reduction in smell, taste, and chemesthesis across the entire cohort of patients that was more profound among those reporting smell and/or taste loss as their presenting symptom. Perceived nasal obstruction accounted for only a small proportion of changes in smell and taste, but not for chemesthesis, supporting viral disruption of sensorineural mechanisms as the dominant aetiology of chemosensory dysfunction. Our study suggests that chemosensory dysfunction in COVID-19 is more widespread than previously reported among Asians and may be related to the infectivity of viral strains.Study Registration: NMRR-20-934-54803 and NCT04390165.
