introduction: lobular capillary hemangioma (lch) is a benign lesion of vascular origin. it rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. case report: in this report we present a case of lch of the nasal cavity which occurred approximately one month after delivery. there was no recurrence after complete endoscopic resection during one ...
objective(s): drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. our studies aim at preparation and characterization of trimethylchitosan-...

BACKGROUND Oxygen therapy is usually combined with a humidification device, to prevent mucosal dryness. Depending on the cannula design, oxygen can be administered pre- or intra-nasally (administration of oxygen in front of the nasal ostia vs cannula system inside the nasal vestibulum). The impact of cannula design on intra-nasal humidity, however, has not been investigated to date. OBJECTIVE...
The nose offers an attractive noninvasive alternative for drug delivery. Nasal anatomy, with a large mucosal surface area and high vascularity, allows for rapid systemic absorption and other potential benefits. However, the complex nasal geometry, including the narrow anterior valve, poses a serious challenge to efficient drug delivery. This barrier, plus the inherent limitations of traditional...
Influenza virus infection in pigs is a major farming problem, causing considerable economic loss and posing a zoonotic threat. In addition the pig is an excellent model for understanding immunity to influenza viruses as this is a natural host pathogen system. Experimentally, influenza virus is delivered to pigs intra-nasally, by intra-tracheal instillation or by aerosol, but there is little dat...
Objective: Several medications have been used for sedation in children in dentistry and intra-nasal route has been reported to be an efficient way regarding patient cooperation. The aim of the present study was to compare the changes in physiologic parameters following intra-nasal midazolam and ketamine administration. Methods: In this randomized cross-over double-blind trial, 17 uncooperat...
Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from t...
