1. Noise exposure, hearing protection and hearing loss. A long-term study at an automobile sheet-metal pressing plant
Sammanfattning : The design and implementation of a hearing conservation programme in a heavy industry with high noise levels is described. Action was taken on several points, including noise measurements, noise reduction, education on hearing protector use, and audiometric monitoring. LÄS MER
2. Long-term follow-up after otitis media in childhood
Sammanfattning : Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. LÄS MER
3. Surface proteins of pathogenic streptococci
Sammanfattning : Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity. LÄS MER
4. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology
Sammanfattning : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. LÄS MER
