Objective:
To explore the roles of the closure disorder of Eustachian tube in occurrence and development of otitis media with effusion (OME).
Methods:
Fifty-six adults with OME, 16 children with OME, 66 health adults and 20 health children were selected according to diagnosis criteria. Sniffing test was measured by Tubo-tymanoaerodynamic graphy and the self-designed questionnaires were surveyed in all cases.
Results:
The positive levels in sniffing test were regarded as external auditory canal press 10dapa lower than baseline of the pressure. The positive rate was 64.86% in adults with OME, which was higher than health adults (P < 0.01). The positive rate was 70.83% in children with OME which was higher than health children (P < 0.05).
Conclusions:
The higher positive rate of sniff test in OME patients suggests that closure disorder in Eustachian tube playing an important role in the occurrence and development of OME.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
