BACKGROUND Otitis media (OM) is the most common paediatric illness for which antibiotics are prescribed. In Australian Aboriginal children OM is frequently asymptomatic and starts at a younger age, is more common and more likely to result in hearing loss than in non-Aboriginal children. Absent transient evoked otoacoustic emissions (TEOAEs) may predict subsequent risk of OM. METHODS 100 Abori...

UNLABELLED Auditory processing depends on afferent and efferent auditory pathways integrity. The efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression. AIM Analyze the efferent auditory system activity by otoacoustic emission suppression and acoustic reflex sensitization in human subjects with audito...

UNLABELLED The workings of the auditory pathway of patients with tinnitus and normal hearing can be associated with an auditory efferent pathway dysfunction at the level of the superior olivary complex. Otoacoustic emission suppression with contralateral noise can represent an alternative to its evaluation. AIM to investigate Transient Otoacoustic Emission suppression in normal hearing adults...

Background & objectives: Prognosis of thyroid papillary cancer is quite well long lasting, so a 10- year survival is observed in more than 90% cases. In this study, rate of incidence of thyroid papillary cancer in contralateral lobe was assessed among patients who had a surgical thyroidectomy re-operation. Materials & Methods: In this retrospective study, we examined 82 patients diagnosed with...

Transient-evoked (TEOAE) and distortion-product otoacoustic emissions (DPOAE) were measured in 51 graduates of an intensive care nursery and compared to data obtained from 80 normal-hearing children and adults. All infants had click-evoked auditory brainstem responses (ABR) at 30 dB nHL or less while the older subjects had pure-tone thresholds of 20 dB HL or less for octave frequencies from 250...

Disease patterns and immunologic parameters were studied employing inbred and Igh-1 disparate congenic mice to determine the role of host genetics and Igh-1-linked gene products in the von Szily model of viral chorioretinitis. Following intracameral inoculation of 1.5 x 10(4) PFU HSV-1 (KOS), 100% of BALB/c (Igh-1a), 62% of A/J (Igh-1e) and none of the C57BL/6J (Igh-1b) inbred mice developed co...

The contribution of the dorsal nucleus of the lateral lemniscus (DNLL) to binaural processing was examined by recording single-unit activity in the rat's inferior colliculus before, during, and after a reversible block of the excitatory activity in DNLL by local injection of kynurenic acid. Recordings were made from the central nucleus of the inferior colliculus with glass micropipettes filled ...

experiments wee performed to evaluate the contralateral effect of adjuvant induced mono arthritis. in these experiments laser doppler imaging (ldi) was used to investigate changes in blood flow. adjuvant was applied to induce chronic inflammation. temperature and knee diameter increased in the first week after administration in the administrated knee joint.substance p (sp) (a neruokinin with a ...
