ABSTRACT
This study provides data on prevalence of Staphylococcus aureus in oropharynx, rhinopharynx and vestibulum nasi. Specimens were taken from these three pharyngeal sites in 346 patients and analysed for S. aureus. Abnormal pharyngeal findings and patient histories were recorded. S. aureus was found in 8.1%, 7.2% and 20.2% of all specimens from oropharynx, rhinopharynx and vestibulum nasi, respectively. A strong association between colonization of oropharynx and rhinopharynx was found, especially when vestibulum nasi was not colonized. These findings can be used in development of more effective meticillin-resistant Staphylococcus aureus decolonization regimes.

Active anterior rhinomanometry was performed on adult healthy snorers before and after uvulopalatopharyngoplasty or laser uvulopalatoplasty. Significant reduction of the nasal airway resistance both before and after pharmacological decongestion of the nasal mucosa was found in a group of 46 patients. Oedema disappearing after surgery may be an explanation for the results.

A new method was developed for continuous measurement of the middle ear pressure during a 24-h period. The equipment consisted of a piezo-electric pressure device and a digital memory. To allow continuous pressure recordings during normal every-day activities the equipment was made light and portable. The measurement accuracy of the equipment as well as the base-line and temperature stability were tested and found to meet to our requirements satisfactorily. In 4 volunteers with different middle ear conditions, a small perforation was made through the tympanic membrane. A rubber stopper containing a small polyethylene tube was fitted into the external ear canal. Tubal function tests were made to establish the equipment's ability to monitor fast pressure changes. The tests were well in accordance with other methods of direct pressure measurements. The equipment was carried by the volunteers for 24 h to monitor any slow or rapid dynamic pressure changes in the middle ear. Four continuous 24-h measurements are presented. The method was found to be suitable for valid measurements of dynamic pressure changes in the middle ear during normal every-day activities. It may become a useful instrument in the search for a better understanding of the development of chronic middle ear disease.
