Effect of intranasal budesonide irrigations on intraocular pressure.

Background: Intranasal and oral corticosteroids are widely used in the management of chronic rhinosinusitis with nasal polyps (CRSwNP). Higher-dose topical nasal steroids (HDTNS) such as budesonide irrigations are increasingly used for long-term maintenance in these patients. Oral steroids have the potential to cause increased intraocular pressure (IOP) and glaucoma.

Disinfection of rigid nasal endoscopes following in vitro contamination with Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, and Haemophilus influenzae.

Importance: If not adequately cleaned, rigid nasal endoscopes (RNEs) have the potential to cause iatrogenic cross-contamination.

Objective: To test the efficacy of various disinfection methods in reducing bacterial load on RNEs in vitro.

Design And Setting: In vitro model.

One-pot syntheses of immunostimulatory glycolipids.

Glycolipids containing alpha-linked galactosyl and glucosyl moieties have been shown to possess unique immunostimulatory activity creating a need for access to diverse and anomerically pure sources of these compounds for immunological studies. To meet this demand, glycosyl iodides were enlisted in the synthesis of these biologically relevant glycoconjugates. In the first-generation protocol, per-O-benzyl galactosyl iodide was efficiently coupled with activated sphingosine acceptors, but fully functionalized ceramides were found to be unreactive.
