Middle meatus bacteriology of acute rhinosinusitis in patients after irradiation of nasopharynx.

Background: Patients who undergo radiotherapy for nasopharyngeal carcinoma (NPC) tend to suffer from rhinosinusitis because irradiation causes damage to sinonasal tissue; however, their bacteriology is lacking in the literature. The aim of this study was to determine the bacteriology and antibiotic resistance in acute rhinosinusitis (ARS) of these patients.

Methods: We collected nasal purulent discharge for bacteriology and antibiotic susceptibility tests in irradiated NPC patients with ARS.

Inflammatory pseudotumor of the nasal cavity.

Inflammatory pseudotumor is usually found in the orbits and lungs, but rarely in the sinonasal area. We present a 59-year-old woman with a right nasal mass. This lesion caused nasal bleeding and blockage.

Methicillin-resistant Staphylococcus aureus infections in acute rhinosinusitis.

Objective/hypothesis: Methicillin-resistant Staphylococcus aureus (MRSA) has recently become a serious problem in various fields of medicine. However, it has rarely been studied in acute rhinosinusitis. The aim of this study was to identify the clinical manifestations and treatment outcome of community-acquired methicillin-resistant S.

High prevalence of antibiotic resistance in isolates from the middle meatus of children and adults with acute rhinosinusitis.

Background: The pathogens in acute rhinosinusitis are similar worldwide. An increase in antibiotic resistance has been shown in a large number of studies in recent years. The prevalence of resistance varies greatly in different countries.
