BACKGROUND Accumulating evidence suggests that vitiligo is a systemic disease affecting the entire pigmentary system. AIM To investigate the subclinical abnormalities of melanin-containing cellular elements of the auditory system in patients with vitiligo. METHODS We studied the conventional audiometric investigations and brainstem auditory evoked responses (BAERs) of 57 active patients wit...

KS is a rare disorder discovered by Japanese doctors Norio Niikawa and Yoshikazu Kuroki in 1981. The syndrome received its name due to the resemblance of the characteristic facial features of patients to the make-up used in the traditional Japanese Kabuki play.1 Niikawa and Kuroki independently described the syndrome in a subset of ten Japanese children that were reported to have distinctive fa...

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. 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....

This study reports on the long-term benefit of ultra-high-frequency masking with the UltraQuiet device. A commercial product, UltraQuiet provides a new form of high-frequency bone conduction therapy. To assess its effectiveness in tinnitus treatment, we selected 15 patients with problematic tinnitus and randomly assigned them to three variations of the medical-audiological tinnitus patient prot...

Hearing loss as assessed by pure-tone audiometry (PTA) is significantly correlated with the intelligibility of synthetic speech. However, PTA is a subjective audiological measure that assesses the entire auditory pathway and does not discriminate between the different afferent and efferent contributions. In this paper, we focus on one particular aspect of hearing that has been shown to correlat...

The development of hearing aids incorporates two aspects, namely, the audiological and the technical point of view. The former focuses on items like the recruitment phenomenon, the speech intelligibility of hearing-impaired persons, or just on the question of hearing comfort. Concerning these subjects, different algorithms intending to improve the hearing ability are presented in this paper. Th...

REVIEW Auditory neuropathy is a disorder characterised by preservation of outer hair cell function, with normal otoacoustic emissions and/or cochlear microphonics, but an absent or distorted auditory brainstem response. PURPOSE This study aimed to objectively assess hearing thresholds in patients with auditory neuropathy, using the auditory steady state response. MATERIALS AND METHODS Thirt...
