BACKGROUND & OBJECTIVE Radiation usually results in paranasal sinusitis in nasopharyngeal carcinoma (NPC) patients, which influences patients' quality of life. This study was to explore the occurrence and influencing factors of paranasal sinusitis in NPC patients before and after radiotherapy. METHODS Clinical data of 381 NPC patients, treated in Cancer Center of Sun Yat-sen University from J...

Orbital complications of sinusitis in children generally occur as a consequence of ethmoid sinusitis due to preferential spread across the lamina papyracea. A case is presented of a subperiosteal abscess (SPA) in the superolateral orbital wall complicating frontal sinusitis in a 6-year-old female. Congenital bony dehiscences exist in the lateral floor of the frontal sinus, which may allow direc...

Acute sinusitis is very common in children and can be classified as bacterial or viral depending on the etiology. The diagnosis of acute sinusitis in children should be based on the presence of clinical findings that are suggestive of acute sinusitis rather than on imaging findings. The diagnosis can be confirmed by performing a culture and sensitivity test of the paranasal discharge. Once the ...

The growing resistance to antimicrobial agents of all respiratory tract bacterial pathogens has made the management of sinusitis more difficult. The upper respiratory tract including the nasopharynx serves as the reservoir for pathogenic bacteria that can cause respiratory infections including sinusitis. During a viral respiratory infection, potential pathogens can relocate from the nasopharynx...

Objective Examine the relationship between depression symptoms and sinonasal inflammatory diseases, and investigate health disparities associated with allergic rhinitis (AR) and sinusitis in the United States. Study Design Cross-sectional analysis of 2014 National Health Interview Survey (NHIS) data. Methods Adult cases of AR and sinusitis were extracted from the 2014 NHIS in addition to de...

Rhinitis and sinusitis are among the most common medical conditions and are frequently associated. In Western societies an estimated 10% to 25% of the population have allergic rhinitis, with 30 to 60 million persons being affected annually in the United States. It is estimated that sinusitis affects 31 million patients annually in the United States. Both rhinitis and sinusitis can significantly...

Maxillary sinusitis of odontogenic origin is a well-known condition in both the dental and otolaryngology communities. It occurs when the Schneiderian membrane is violated by conditions arising from dentoalveolar unit. This type of sinusitis differs in its pathophysiology, microbiology, diagnostics and management from sinusitis of other causes, therefore, failure to accurately identify a dental...

To distinguish sinusitis from uncomplicated "colds," we examined lactoferrin and eosinophilic cationic protein (ECP) in nasal secretions. Lactoferrin titers were >/=1:400 in 4% of persons with uncomplicated colds and controls but in 79% of persons with sinusitis or purulent sputa. ECP levels were >200 ng/ml in 61% of persons with colds and >3,000 ng/ml in 62% of persons with sinusitis. Nasal la...
