oVEMP as an objective indicator of successful repositioning maneuver.

Background And Objective: Benign paroxysmal positioning vertigo (BPPV) is the most common peripheral vestibular disorder. Canalolithiasis in the posterior semi-circular canal is the most common underlying pathology that can be treated effectively by repositioning maneuvers. Our hypothesis suggested that successful maneuvers can lead to repositioning of dislodged otoconia to the utricle.

Screening for auditory processing performance in primary school children.

Background: A deficit in the processing of auditory information may underlie problems in understanding speech in the presence of background noise, degraded speech, and in following spoken instructions. Children with auditory processing disorders are challenged in the classroom because of ambient noise levels and maybe at risk for learning disabilities.

Purpose: 1) Set up and execute screening protocol for auditory processing performance (APP) in primary school children.

Screening for the mitochondrial A1555G mutation among Egyptian patients with non-syndromic, sensorineural hearing loss.

Background & Aim: Hearing loss is the most frequent form of neurosensory deficit in humans. Although the majority of hereditary hearing loss is due to nuclear gene mutations, it has become clear the significant contribution of mitochondrial genes. The first mitochondrial mutation shown to cause non-syndromic hearing loss in humans was the A1555G mutation in the small ribosomal RNA gene (12S rRNA).
