Test/retest repeatability of effect contralateral acoustic stimulation on the magnitudes of distortion product ototacoustic emissions.

Objectives/hypothesis: Contralateral inhibition of distortion product otoacoustic emissions (DPOAE) has become an important tool to assess the functioning of the medial olivocochlear efferents in humans. However, before this measurement can be applied clinically, the test/retest repeatability needs to be established. Therefore, the current study aimed at evaluating intra- and intersession test/retest repeatability of contralateral inhibition of DPOAE at 2f(1) -f(2) .

Acute gastrointestinal emergencies requiring surgery in children.

Background: Although abdominal pain is common in the paediatric age group, problems of misdiagnosis and serious consequences are more particular in an emergency setting. This study examined the aetiologies of acute abdominal emergencies in children.

Materials And Methods: This was a retrospective study of 100 children below the age of 12 years presenting with acute abdominal emergencies (gastrointestinal) requiring operative interventions.
