OBJECTIVE To assess the prevalence of hearing impairment in siblings of children with profound to total hearing impairment. METHOD Two hundred and twenty siblings of children at a deaf school in Karachi completed the screening program. This consisted of a questionnaire and pure tone audiometry. RESULTS One out of three (73 siblings) had a threshold of 25 dB or greater in their better ear. I...

BACKGROUND Hearing loss is the most common sensory deficit in elderly patients, and is often under-recognised and poorly managed. It is essential for all clinicians to have awareness and knowledge in this field to enable the institution of early and appropriate care. OBJECTIVE The goal of this article is to review the causes, diagnosis and management of hearing loss as it applies to elderly p...

UNLABELLED Mismatch Negativity (MMN) is used to evaluate the central auditory system. AIM to characterize the MMN, in normal subjects. MATERIALS AND METHODS prospective study, 12 subjects, six males and six females, between the ages of 18 and 24. "Mann-Whytnei" test. EXAMS: Pure Tone Audiometry (PTA), Tympanometry, Otoacoustic Emissions and Short and Long Latency Auditory Potentials (MMN). ...

STUDY OBJECTIVE The aims were (1) to evaluate impedance measurements against pure tone audiometry as a screening method for the detection of middle ear changes associated with hearing loss in infant school children; (2) to estimate the costs of the health authority of each method. DESIGN The study involved two stage screening in which both methods were offered, pure tone audiometry being carr...

multiple sclerosis (ms) is a demyelinating disorder of central nervous system. it involves 8th cranial nerve and its central nuclei and is an uncommon cause of the sensorineural hearing loss. for determining the prevalence of hearing loss (hl) especially retrocochlear type in ms, a cross-sectional study was designed using pure-tone audiometry (pta), otoacustic emissions (oaes), auditory brainst...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

background and objective : obstructive sleep apnea (osa) through hypoxia and reoxygenation periods leads to oxidative stress, endothelial dysfunction, and activation of inflammatory cycles, which eventually may cause disorder in vasa nervorum, and peripheral neuropathy in hearing pathway. in this study, we aimed to evaluate the effect of severe sleep apnea on hearing function. materials and met...

UNLABELLED Exposure to noise has a harmful effect on the auditory health of workers. AIM The main goal of this paper was to establish the role of pure-tone audiometry and evoked transient otoacoustic emissions in the detection of small temporary auditory changes after exposure to high sound pressure levels. STUDY DESIGN A cross-sectional cohort study. MATERIAL AND METHODS 30 otologically ...

the aim of the current study is to investigate hearing function in patients with allergic rhinitis. fifty-eight patients with positive skin prick test (group 1) (116 ears) and    31 subjects with negative skin prick test (62 ears) as group 2 were included. pure tone audiometry at 250,500, 1000, 2000, 4000 and 8000 hz and immittance measures, including tympanometry and acoustic reflex tests, wer...
