Loss and recovery of sound-evoked otoacoustic emissions in young chicks following acoustic trauma.

Young and adult chickens exhibit substantial inner-ear damage and post-exposure deterioration in cochlear nerve activity following exposure to intense sound. Both the structural and functional losses largely recover in both age groups within 2-4 weeks after exposure. However, some aspects of acoustic trauma differ between the young and adult chicken ear.

Granular cell tumor of the trachea in pregnancy: a case report and review of literature.

Objectives/hypothesis: The objectives were to present a case report of a woman with recurrent disease during consecutive pregnancies and to discuss the diagnosis and management of granular cell tracheal tumors, with particular attention to pregnancy and hyperestrogenic states.

Study Design: Case report and literature review.

Methods: A Medline search and comprehensive review of literature to assess all cases of granular cell tumors of the trachea were compared and collected, with particular attention to individual cases of pregnancy or cases related to the hyperestrogenic state.
