1	Tympanometry and Middle Ear Effusion McNutt, Laura 05 1900 (has links) Research was conducted on twenty-seven preoperative myringotomy patients to clarify the correlation between tympanometry type and the presence of middle ear effusion. Test results indicate that the relationship between tympanometry and middle ear effusion is dependent on the amount of fluid present. In impacted ears primarily Type B tympanograms were obtained whereas for less than impacted ears all tympanogram types were seen. Also suggested was that a combination of height of the tympanogram and the amount of negative pressure may be diagnostically more important than negative pressure alone as an indicator of effusion. It was recommended that other measures in addition to tympanometry be employed in the diagnosis of middle ear effusion and that further research is needed to achieve optimal use of impedance audiometry. tympanometry Otitis media -- Diagnosis.

2	Impedance Audiometry in Serous Otitis Media Morff, Rosemary 08 1900 (has links) Effectiveness of impedance audiometry in diagnosing serous otitis media in children was examined in this study. The impedance test battery was performed on seventy-six ears of pre-myringotomy children (Mean age: 4.6 years). The status of the middle ear was assessed by the operating physician during surgery, and impedance results were correlated with the operative findings. Middle ear effusion was the variable that most influenced impedance results. Acoustic reflex threshold and tympanometry were the most sensitive tests in predicting effusion. Multiple correlations between these tests and the presence of significant effusion indicated that both measures together are diagnostically more sensitive than either test alone. Also, reflex measurement at one test frequency is as accurate a predictor of effusion as reflex measurement at all frequencies. ear disorders middle ear effusion audiometry delayed language development tympanometry Otitis media -- Diagnosis.

3	Respiratory Infections in Ambulatory Adults. Choosing the Best Treatment Perlman, P E., Ginn, D R. 01 January 1990 (has links) The diagnosis and treatment of respiratory tract infections in ambulatory adults is challenging. The prevalence of these conditions outstrips the medical profession's efficiency and effectiveness in dealing with them. However, selecting diagnostic techniques that identify causative organisms and therapeutic agents targeted to those organisms should lead to a reduction in the morbidity and mortality associated with these illnesses. adult aged ambulatory care anti-bacterial agents (therapeutic use) bronchitis (diagnosis drug therapy etiology) child common cold (diagnosis etiology prevention & control therapy) diagnosis differential epiglottitis (diagnosis) humans influenza human (diagnosis etiology prevention & control therapy) middle aged otitis media (diagnosis drug therapy) pharyngitis (diagnosis drug therapy etiology) pneumonia (diagnosis therapy) respiratory tract infections (diagnosis etiology therapy) sinusitis (diagnosis drug therapy etiology) virus diseases (complications) QCOM
