Listening to Sentences in Noise: Revealing Binaural Hearing Challenges in Patients with Schizophrenia.

Objective: The present, case-control, study investigates binaural hearing performance in schizophrenia patients towards sentences presented in quiet and noise.

Methods: 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.

Abnormal Auditory Brainstem Response (ABR) Findings in a Near-Normal Hearing Child with Noonan Syndrome.

Introduction: Noonan syndrome (NS) is a heterogeneous genetic disease that affects many parts of the body. It was named after Dr. Jacqueline Anne Noonan, a paediatric cardiologist.

Gender Disparities in Speech-evoked Auditory Brainstem Response in Healthy Adults.

Objectives: Gender disparities in speech-evoked auditory brainstem response (speech-ABR) outcomes have been reported, but the literature is limited. 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.

Are speech-evoked auditory brainstem response (speech-ABR) outcomes influenced by ethnicity?

Due to its objective nature, auditory brainstem response (ABR) evoked by complex stimuli has been gaining attention lately. 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.

The Hyperactivity of Efferent Auditory System in Patients with Schizophrenia: A Transient Evoked Otoacoustic Emissions Study.

Objective: Electrophysiological studies, which are mostly focused on afferent pathway, have proven that auditory processing deficits exist in patients with schizophrenia. Nevertheless, reports on the suppressive effect of efferent auditory pathway on cochlear outer hair cells among schizophrenia patients are limited. The present, case-control, study examined the contralateral suppression of transient evoked otoacoustic emissions (TEOAEs) in patients with schizophrenia.

Evaluation of auditory hallucinations in patients with schizophrenia: A validation study of the Malay version of Psychotic Symptom Rating Scales (PSYRATS).

The Psychotic Symptom Rating Scales (PSYRATS) is the most widely used validated scale to measure the specific symptoms of auditory hallucination and delusion. The aim of this study was to validate and to examine the psychometric properties of the auditory hallucination component of the Malay PSYRATS (MyPSYRATS). The research was done in the Universiti Kebangsaan Malaysia Medical Center (UKMMC) among 51 schizophrenia inpatients and outpatients who had experienced or reported verbal auditory hallucination.

Extensive dural sinus thrombosis and bilateral lateral rectus palsy as an uncommon complication of chronic suppurative otitis media.

Dural venous sinus thrombosis, especially of the sigmoid sinus, is a known but uncommon intracranial extradural complication of chronic suppurative otitis media. Even rarer is the simultaneous occurrence of bilateral abducens palsy in the same patient. We report the case of an adolescent male who presented with signs of raised intracranial pressure, diplopia and bilateral lateral rectus palsy associated with a history of left ear discharge and neck swelling.

Clinical use of Malay Version of Vertigo Symptom Scale (MWSS) in patients with peripheral vestibular disorder (PVD).

Introduction: The Vertigo symptom scale (VSS) is a well established tool for the evaluation of vestibular disorders and the associated symptoms of autonomic arousal and somatosensation. By using a validated Malay version of vertigo symptom scale (MVVSS) questionnaire, the severity of the vertigo from patients' perspective can be determined and rated. Before MVVSS can be applied clinically among Malaysians, it was of interest to determine its clinical value in identifying vestibular disorders.

The performance of distortion product otoacoustic emissions and automated auditory brainstem response in the same ear of the babies in neonatal unit.

Objective: To identify the outcomes of hearing screening using different protocols of both Distortion Product Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Response (AABR) tests in the same ear of the babies in a neonatal unit population.

Methods: A cross-sectional study was carried out on babies who were admitted into a neonatal unit. By using a formula of single proportion and considering 20% drop out, the number of sample required was 114.

Outcome of a newborn hearing screening program in a tertiary hospital in Malaysia: the first five years.

Background And Objective: Universal newborn hearing screening (UNHS) was started in the Hospital Universiti Sains Malaysia (HUSM) in January 2003. To comply with international standards, we determined the outcome of the newborn hearing screening program for the first 5 years of its implementation, from January 2003 to December 2007.

Methods: The program screened all infants who were delivered in HUSM.

Facial profile shape, malocclusion and palatal morphology in Malay obstructive sleep apnea patients.

Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA).

Materials And Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean +/- standard deviation [SD], 33.2 +/- 13.

Assessment of 3-D nasal airway morphology in Southeast Asian adults with obstructive sleep apnea using acoustic rhinometry.

The aim of the present study is to investigate nasal airway morphology in Asian adults with and without obstructive sleep apnea (OSA) using acoustic rhinometry (AR), principal components analysis (PCA), and 3-D finite-element analysis (FEA). One hundred eight adult Malays aged 18-65 years (mean ± SD, 33.2 ± 13.

Craniofacial obesity in patients with obstructive sleep apnea.

Introduction: Obstructive sleep apnea (OSA) and obesity are serious, widespread public health issues.

Objective: To localize and quantify geometric morphometric differences in facial soft tissue morphology in adults with and without OSA.

Materials And Methods: Eighty adult Malays, consisting of 40 patients with OSA and 40 non-OSA controls, were studied.

Cranial base and airway morphology in adult malays with obstructive sleep apnoea.

Background: Obstructive sleep apnoea (OSA) has been described as a public health problem comparable to smoking in its impacts upon society.

Objective: To compare the differences in cranial base and airway morphology in Malay adults with and without OSA using finite element analysis (FEM).

Method: Lateral skull radiographs of 38 adult Malays aged 18-60 years were divided into two groups of 19 (13 male, 6 female).

Clinical and audiological profiles in children with chronic otitis media with effusion requiring surgical intervention.

To determine the characteristic presenting symptoms, otoscopic findings, audiological profiles and the intraoperative findings of children with chronic otitis media with effusion who required surgical intervention. A prospective cross sectional study was undertaken in the otorhinolaryngology clinic of USM Hospital (HUSM) involving 25 cases (50 ears) of children with chronic otitis media with effusion requiring surgical intervention from June 1999 to September 2001. Their ages ranged from 3 to 12 years old.
