Click-evoked otoacoustic emissions (cEOAEs) were repeatedly recorded in an operational sample of 144 very low birth weight (VLBW) infants. A subgroup of 22 was composed of all those babies in which at least 4 recordings were successfully done. The mean birth weight of this group was 1040 g, and the mean duration of assisted ventilation was 17 days. The OAE-recordings were done in the post conce...

The measurement of otoacoustic emissions (OAE) allows for an objective examination of the cochlear function. However, the validity of OAE tests is affected negatively by calibration errors, rendering the diagnosis less accurate. In this report, we shed light on the evanescent waves arising at the interface between the OAE probe and the ear canal. For this purpose, finite element models of the e...

A high prevalence of epilepsy is reported in many onchocerciasis-endemic regions. In this paper we discuss recent epidemiological and clinical aspects as well as public health implications of onchocerciasis-associated epilepsy (OAE) and propose a strategy to reduce the burden of disease. OAE probably presents in a variety of clinical manifestations, including the nodding syndrome and the Nakala...

Hearing loss is the most common of all disabilities in China, with three million of the 1.4 billion population affected. Recently, the release of an official neonatal hearing screening consensus has drawn attention to the importance of continued surveillance throughout childhood and the need for a system that is suited to the Chinese situation. The current research aimed to develop and evaluate...

The Coniacian–Santonian time interval is the inferred time of oceanic anoxic event 3 (OAE 3), the last of the Cretaceous OAEs. A detailed look on the temporal and spatial distribution of organic-rich deposits attributed to OAE 3 suggests that black shale occurrences are restricted to the equatorial to mid-latitudinal Atlantic and adjacent basins, shelves and epicontinental seas like parts of th...

Community echocardiography refers to cardiac ultrasound imaging which is requested by, reported to, and acted upon by general practitioners. Mobile laboratories can conveniently take echo technology to the patient in the community and may occasionally be appropriate in a large general practice. More usually, however, this represents an ineYcient use of staV time and resources, as well as exposi...

OBJECTIVES To evaluate the frequency of risk factors and their influence on the evoked otoacoustic emission (OAE) of infants. METHODS All newborns between November 2009 and June 2012 in Haydarpaşa Numune Education and Research Hospital were tested on distortion evoked OAE screening test. Total of 2,284 infants were examined. Sex, maternal infectious disease, birth type (vaginal birth or caesa...

Anesthesia effects on otoacoustic emission (OAE) recordings were evaluated in a group of 72 Sprague-Dawley rats (mean weight 225+/-20 gr). Two anesthesia dosages (high and normal) and two anesthetic protocols (ketamine-xylazine, ketamine-xylazine-atropine) were tested. Transient evoked OAE (TEOAE) and distortion product OAE (DPOAE) responses were recorded in 10 min intervals, for a total period...

INTRODUCTION This study was designed to compare the sensitivity and specificity of detecting sensorineural hearing loss (SNHL) using the transient-evoked otoacoustic emissions (OAE) machine (the Madsen TE Echoscreen) and automated auditory brainstem response (AABR) machine (the Sabre Compac portable AABR) in term neonates exposed to severe hyperbilirubinaemia. METHODS This was a prospective s...
