Factors affecting bacterial biofilm expression in XXXX and the influences on prognosis.

@entity1 @entity174 @entity5381 @entity102
PURPOSE: The purpose of the study was to investigate the expression of bacterial biofilm (BF) for @entity102 ( @entity102 ) and to find out factors affecting BF expression and the influences on its prognosis. MATERIALS AND METHODS: All specimens were analyzed by a scanning electron microscope and bacterial cultivation from a panel of 93 @entity1 with @entity102 , 20 with @entity5381 , and 17 with @entity174 as the control group. Referring to the grade classification criteria from the sinusitis-specific questionnaire Sino-Nasal Outcome Test-20, @entity1 were assessed preoperatively based on common clinical manifestations. @entity1 were followed up for condition improvement as assessed by visual analogue scale and nasal endoscopic examination. RESULTS: In the experimental group, among all the @entity1 , 3 were lost (lost 3.2%). Bacterial biofilm was positive in 64 (71.1%) of 90 @entity1 . Mucosal cilia were observed in varying degrees of injury. Bacterial culture was positive in 60 (66.7%) @entity1 . In the control group, no BF was found and no bacterium was cultured. Bacterial biofilm expression was correlated with the bacterial culture. The BF(+) @entity1 ' visual analogue scale scores 6 months and 1 year postoperation were lower than the BF(-) @entity1 ' scores (P < .05). The BF(+) @entity1 ' Lund-Kennedy scores at 6 months and 1 year postoperation were higher than the BF(-) @entity1 ' scores (P < .05). CONCLUSIONS: Bacterial biofilm is involved in the pathogenesis of @entity102 and is associated with the bacterial culture. Bacterial biofilm has a certain impact on @entity1 ' prognosis.
