Sinusitis, enlarged nasal turbinates, tumors, infections, hearing disorders, allergic conditions, facial fractures and other disorders of the ear, nose and throat are diagnosed and / or treated using minimally invasive approaches and, in many cases, flexible catheters as opposed to instruments having rigid shafts. Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air / gas flow studies, anatomic dimension studies, endoscopic studies and transillumination studies. Access and occluder devices may be used to establish fluid tight seals in the anterior or posterior nasal cavities / nasopharynx and to facilitate insertion of working devices (e.g., scopes, guidewires, catheters, tissue cutting or remodeling devices, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting devices, substance delivery implants, etc.

This invention is for nasal adaptors for oral inhaler devices and methods of adapting an oral inhaler device with a nasal adaptor. The nasal adaptor of the present invention, in assembly with an oral metered dose aerosol inhaler converts an oral inhaler device to nasal delivery. The nasal adaptor in assembly with an oral inhaler device when in operation, simultaneously administers an inhalant to the nasal mucosa and down to the bronchial tree and lungs. In this manner a nasally delivered anti-inflammatory agent would travel down the same route as an allergen would—the nostril, nasal cavity, nasopharynx, trachea, bronchi and lung tissues.

The present invention relates to modifying rapid immunochromatographic (“ICT”) tests for the detection of characteristic carbohydrate antigens of bacteria that are known to be causative of otitis media and respiratory diseases in children under the age of approximately 12 years. Children of this age group are also prone to nasopharyngeal colonization with the same bacteria, and urine samples taken from colonized, but otherwise healthy, children were shown to exhibit an unduly high incidence of test results that were false positive for the presence of disease. The test modifications, which maintain the test sensitivity unchanged and the test specificity at a value above 90% were developed to insure that healthy, albeit colonized, children were not medicated for disease the bacteria are known to cause. The modifications involve either (1) reducing the total amount of antibodies to the carbohydrate antigen employed in each test, (2) adding at least one fixed “scrub” line located just prior to the capture line in the sample flow path to the preprepared ICT test strip to “scrub” out an identical amount of target antigen from all bodily fluid test samples obtained from both colonized but otherwise healthy children and diseased children, or (3) combinations of (1) and (2).
