HSI may be beneficial in improving surgical field of view in FESS after 2 hours of operating time. A significant reduction in rate of blood loss may be attained with HSI.

The MAD is likely a safe and effective method of delivering budesonide to the sinuses in the short term.

Chronic granulomatous invasive fungal sinusitis (CGIFS) is a peculiar disease of the paranasal sinuses due to its rarity, patient subset, and disease course. We describe 7 cases of histopathologically confirmed CGIFS with different treatment plans and varying outcomes. Of particular note was that one of these patients developed allergic fungal rhinosinusitis after complete resolution of his primary invasive disease, a finding that has never been reported in the literature. Another patient had an atypical fungal species ( Aspergillus nidulans) on fungal stain and culture, while one immunodeficient patient had a large intracerebral disease component and died after 2 months of treatment. We also present a review of the pertinent literature investigating this rare disease.

Compared to the current diagnostic gold standard, SNOT-22 scores greater than 21 sufficiently identified adults with CF presenting with concomitant CRS. The SNOT-22 is a simple instrument that can easily be implemented in adult CF clinics to assist care providers identify individuals requiring more detailed assessment or referral to a sinus clinic.

BACKGROUNDThe Sino-Nasal Outcome Test (SNOT)-22 has multiple items that reflect how nasal disease affects quality of life. Currently, no validated Arabic version of the SNOT-22 is available.OBJECTIVETo develop an Arabic-validated version of SNOT-22.DESIGNProspective.SETTINGTertiary care center.PATIENT AND METHODSThis single-center validation study was conducted between 2015 and 2017 at King Abdul-Aziz University Hospital, Riyadh, Saudi Arabia. The SNOT-22 English version was translated into Arabic by the forward and backward method. The test and retest reliability, internal consistency, responsiveness to surgical treatment, discriminant validity, sensitivity and specificity all were tested.MAIN OUTCOME MEASURESValidated Arabic version of the SNOT-22.RESULTSOf 265 individuals, 171 were healthy volunteers and 94 were chronic rhinosinusitis patients. The Arabic version showed high internal consistency (Cronbach’s of 0.94), and the ability to differentiate between diseased and healthy volunteers (P<.001). The translated versions demonstrated the ability to detect the change scores significantly in response to intervention (P<.001).CONCLUSIONThis is the first validated Arabic version of SNOT-22. The instrument can be used among the Arabic population.LIMITATIONSNo subjects from other Arab countries.
