Limitation of Conventional Audiometry in Identifying Hidden Hearing Loss in Acute Noise Exposure.

Purpose: The concept of hidden hearing loss can explain the discrepancy between a listener's perception of hearing ability and hearing evaluation using pure tone audiograms. This study investigated the utility of the suprathreshold auditory brainstem response (ABR) for the evaluation of hidden hearing loss in noise-exposed ear with normal audiograms.

Materials And Methods: A total of 15 patients (24 ears) with normal auditory thresholds and normal distortion product otoacoustic emissions were included in a retrospective analysis of medical records of 80 patients presenting with histories of acute noise exposure.

Classification of trace patterns of 226- and 1000-Hz tympanometry in healthy neonates.

Objective: Accurate evaluation of middle ear function is a challenge especially in babies referred from newborn hearing screening programs. The aim was to assess the feasibility of tympanometry using 226- and 1000-Hz probe tones in neonates.

Methods: Hearing was evaluated by transient evoked otoacoustic emission (TEOAE) in 96 ears of healthy neonates in well-baby nursery.

Changes in body fat mass in patients after starting peritoneal dialysis.

Background: Peritoneal dialysis (PD) is characterized by gain in fat mass. Visceral fat mass is associated with metabolic syndrome and atherosclerosis rather than subcutaneous fat mass. In addition, the change in visceral fat mass is a more reliable predictor of survival in PD patients.
