The present study was conducted to compare 40-Hz ASSR thresholds between ipsilateral and contralateral recordings at specific test frequencies. Twenty young female subjects with normal hearing bilaterally (hearing level ≤ 20 dB HL across speech frequencies) were included in the study. One-octave-wide narrow band CE-chirp® stimuli centred at 500, 1000, 2000 and 4000 Hz with 40 Hz modulation frequency (MF) were presented ipsilaterally and contralaterally to each subject through insert earphones. The ASSR thresholds were obtained for each recording condition. The mean ASSR thresholds were higher for contralateral recording than for ipsilateral recording at all test frequencies, but analysis using the paired t-test revealed that the differences were not significant at any of the test frequencies (p>0.05). Comparing the ASSR thresholds among the test ...

Three cases of tracheobronchial foreign bodies in children less than two years old are described. One of the foreign bodies was unsuspected; the other two were probably related to food habits. All three cases improved without sequelae following prompt bronchoscopic intervention. Young children should not be given food containing bones or hard chitinous shells.

Human amniotic membrane was used in 20 patients while temporalis fascia was used in the remaining 30. Anatomical closure of the perforation and reduction of the air-bone gap was measured. The graft uptake showed a 65% success rate for the amniotic membrane and 56.7% for the temporalis fascia at 3 months post-operatively. Significant closure of air-bone gap was observed in the human amniotic group. These results indicate comparable outcomes between human amniotic membrane and the temporalis fascia graft.

The association between adenoid inflammation and OME has long been noted but the exact mechanism is still much debated. We studied the role of adenoid mast cells in the causation of OME.Objective: To study the distribution and role of adenoid mast cells in the causation of OMEMethodology: A cross-sectional, prospective study was carried out in the otorhinolaryngologic clinic, department of otorhinolaryngology (ORL), Science University of Malaysia, from June 1999 to September 2001. A total number of 50 cases were studied. Twenty-five of these patients underwent adenoidectomy, while another 25 patients underwent adenoidectomy and myringotomy with ventilation tube insertion. The adenoid specimens from all patients were examined for the number of adenoid mast cells present, using light microscopy and...

The otologic assessment together with high-resolution CT images is an important step to obtain precise diagnostic profile of ear malformations. This study was conducted to obtain the detailed anatomy and objective assessment of the ear in patients presenting with hearing loss in a tertiary care otologic center using high-resolution CT scan. METHODS: A cross-sectional study of 55 patients with hearing loss who had undergone high-resolution CT scans at Hospital Universiti Sains Malaysia from 1st January 2008 until 31st May 2014. Patients with temporal bone fractures, malignancy, post-operative ear and cholesteatoma were excluded. RESULTS: Nine patients noted to have external ear anomaly on right ear and 7 patients on left ear. Middle ear abnormality in both ears was seen in 2 patients. Patients noted to have cochlear anomaly on the right ear (R) were 8 and left ear (L) were 4. Measurements of vestibular aqueduct diameter were 0.08 ...

The aim of the study was to develop and validate a new questionnaire for documenting the progress of the auditory training among Malay hearing impaired children. Materials and Methods: In the first phase of this validation study, Malay version of Parental Report on Auditory Training (MyPRAT) questionnaire was developed accordingly. In the second phase, the validity and reliability of MyPRAT were determined. Specifically, its content validity (n=9), face validity (n=33) and construct validity (n=11) were tested. For reliability analysis, its internal consistency was determined by means of item-total correlation, Cronbach’s alpha and split-half reliability. Results: As reported by clinical experts, content validity index (CVI) values of MyPRAT were high (0.78-1.00) indicating ex...

It was named after Dr. Jacqueline Anne Noonan, a paediatric cardiologist. Case Report: We report audiological tests and auditory brainstem response (ABR) findings in a 5-year old Malay boy with NS. Despite showing the marked signs of NS, the child could only produce a few meaningful words. Audiological tests found him to have bilateral mild conductive hearing loss at low frequencies. In ABR testing, despite having good waveform morphology, the results were atypical. Absolute latency of wave V was normal but interpeak latencies of wave’s I-V, I-II, II-III were prolonged. Interestingly, interpeak latency of waves III-V was abnormally shorter. Conclusion: Abnormal ABR results are possibly due to abnormal anatomical condition of brainstem and might contribute to speech delay.

Participants were twenty-one healthy controls and sixteen schizophrenia patients with normal peripheral auditory functions. The binaural hearing was examined in four listening conditions by using the Malay version of hearing in noise test. The syntactically and semantically correct sentences were presented via headphones to the randomly selected subjects. In each condition, the adaptively obtained reception thresholds for speech (RTS) were used to determine RTS noise composite and spatial release from masking. Schizophrenia patients demonstrated significantly higher mean RTS value relative to healthy controls (p=0.018). The large effect size found in three listening conditions, i.e., in quiet (d=1.07), noise right (d=0.88) and noise composite (d=0.90) indicates statistically significant difference between the groups. However, noise fron...

The present study was performed to further verify this issue and determine the influence of head size on speech-ABR results between genders. 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 con...

The present study aimed to compare the speech-evoked auditory brainstem response (speech-ABR) results between two ethnic groups: Malay and Chinese. In addition, it was also of interest to compare the speech-ABR outcomes obtained from the present study with the published Caucasian data. Thirty healthy male adults (15 Malay and 15 Chinese) were enrolled in this comparative study. Speech syllable/da/presented at 80 dBnHL was used to record speech-ABR waveforms from the right ear of each subject. Amplitudes and latencies of speech-ABR peaks (V, A, C, D, E, F and O), as well as composite onset measures (V/A duration, V/A amplitude and V/A slope) were computed and analyzed. When the two ethnic groups were compared, all speech-ABR results were not statistically different from each other (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 0.05). When the data from the present study were compared with the published Caucasian data, most of the statistical analyses were significant (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). That is, Asian subjects revealed significantly higher peak amplitudes, earlier peak latencies, higher V/A amplitudes and steeper V/A slopes than that of Caucasians. The speech-ABR results between Malay and Chinese were found to be essentially similar due to anatomical similarities. Nevertheless, specific normative data for Asian adults are required as their speech-ABR results are different from that of Caucasian males. This issue should be addressed before it can be applied holistically in multiracial countries.

As human brain regulates various systems of human body, its dysfunction could lead to multiple symptoms found in schizophrenia. These include but not limited to auditory hallucinations and deficiency in speech and language processing. Since auditory hallucinations, speech and language are related to hearing, it is reasonably acceptable that auditory related functions were affected in patients with schizophrenia. Moreover, as auditory hallucinations are common symptoms in schizophrenia, investigating auditory processing system in the affected patients is important. Perhaps this could, in general, clarify our understanding on the mechanism of schizophrenia. Reports on auditory processing deficits in patients with schizophrenia have been widely documented. 6-9 As previously
