otitis media with effusion (ome) is very common in pediatric patients. immune reactions in serum and middle ear system play roles in the etiology, pathogenesis and prevention of otitis media. immunologically active antigens interact with immunocompetent cells in the lamina propria of the middle ear to produce a local immune response. in this investigation, 32 sera and 50 middle ear fluid sample...

The 41 papers that compose this volume were presented at the McCollumPratt Institute Symposium in the spring of 1958. They fall into four broad categories entitled Developmental Cytology, Cellular and Tissue Interactions in Development, Problems of Specificity in Development, and Control Mechanism in Development. Many of the current leaders in developmental biology contribute to the book either...

M odern industry has produced a noisy world. The din of jack­ hammers, the whine of jet engines and the blare of amplified electric guitars have become all too commonplace. It was therefore con­ siderate of nature to have equipped the human ear with a rather sophis­ ticated noise-reduction system: two small muscles that are attached to the ossicles, the tiny bones that connect the eardrum to th...

This study was undertaken to develop a functional model of otitis media with effusion (OME) in the pig (Sus scrofa), with the purpose of investigating the origin of lymphocytes populating the middle ear during the course of an inflammatory process. The relevance of the model to the human condition of OME is to a large extent dependent on the anatomical and physiological similarities between the...

Otitis media (OM) (a middle ear infection) is a common childhood illness that can leave some children with permanent hearing loss. OM can arise following infection with a variety of different pathogens, including a coinfection with influenza A virus (IAV) and Streptococcus pneumoniae (the pneumococcus). We and others have demonstrated that coinfection with IAV facilitates the replication of pne...

OBJECTIVES Wideband reflectance (WBR) is a middle ear analysis technique that quantifies frequency-specific sound conduction over a wide range of frequencies. One shortcoming of WBR is that there is limited normative data, particularly for pediatric populations and children with middle ear pathology. The goals of this study were to establish normative WBR data for early school-aged children; to...
