BACKGROUND The purpose of this study was to investigate hearing threshold changes of workers with unilateral conductive hearing loss who were exposed to workplace noise for 8-years. METHODS Among 1819 workers at a shipyard in Ulsan, 78 subjects with an air-bone gap ≥10 dBHL in unilateral ears were selected. Factors that could affect hearing were acquired from questionnaires, physical examinat...

OBJECTIVE To investigate the hypothesis that second-hand smoke (SHS) exposure is associated with sensorineural hearing loss (SNHL) in adolescents. DESIGN A complex, multistage, stratified geographic area design for collecting representative data from the noninstitutionalized US population. PARTICIPANTS Cross-sectional data from National Health and Nutrition Examination Survey (2005-2006) we...

introduction: children learn to communicate by hearing sounds. if there is hearing loss, the cognitive and speaking abilities and language learning will deteriorate. early detection and intervention are important factors in the successful treatment of hearing loss in children. hearing loss (hl) is divided into two main groups: conductive hearing loss (chl) and sensorineural hearing loss (snhl),...

BACKGROUND AND OBJECTIVE Congenital cytomegalovirus (cCMV) infection remains a leading cause of childhood hearing loss. Currently universal CMV screening at birth does not exist in the United States. An alternative approach could be testing infants who do not pass their newborn hearing screening (NHS) for cCMV. This study was undertaken to evaluate whether a targeted approach will identify infa...

Introduction  Several authors have demonstrated the relationship between sudden sensorineural hearing loss (SNHL) and systemic autoimmune diseases (SAD). Immune-mediated SNHL can rarely present as unilateral sudden SNHL and manifests itself in the contralateral ear only after years. It presents clinical relevance for being one of the few SNHL that may be reversible given that early and appropri...

OBJECTIVE We evaluated the causes of hearing loss found after failed universal newborn hearing screening and compared the results with the previously used behavioral observation test (Ewing/CAPAS). STUDY DESIGN Hearing loss in neonates, born between September 1999 and October 2007 and referred to our center after failed screening, was determined by audiologic testing and physical examination....

conclusion we concluded that cmv is the most common cause of intrauterine infection in infants aged less than 6 months as compared to the healthy ones. we prefer, at least in our country, to consider seropositive (cmv-igm) infants suspected of intrauterine infection (less than 6 months) as congenital form. to arrest the natural progression of congenital cmv, we recommend prolonged course of ora...

The association between congenital cytomegalovirus (CMV) infection and sensorineural hearing loss (SNHL) was first described almost 50 years ago. Studies over the intervening decades have further described the relationship between congenital CMV infection and SNHL in children. However, congenital CMV infection remains a leading cause of SNHL in children in the United States and the world today....

INTRODUCTION AND OBJECTIVE Hearing plays an essential role in the acquisition, development and maintenance of the properties of the speech and language. Birth weight is an indicator of biological maturation of the newborn. Premature newborns with very low birth weight (VLBW<1,500 g) constitute a group with the highest risk of sensorineural hearing loss. Our objective was to ascertain the degree...
