BACKGROUND Nose and mouth leaks impair effective pressure transmission during neonatal continuous positive airway pressure (CPAP), but little is known about how these leaks affect physiological parameters. This study investigated the influence of nose leaks and spontaneous mouth opening on peripheral oxygen saturation (SpO₂) and respiratory rate (RR) using nasopharyngeal CPAP. METHODS In 32 n...

INTRODUCTION Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair. CASE REPORT A 2 days old female ...

BACKGROUND Supernumerary nostril is a congenital anomaly that contains additional nostril with or without accessory cartilage. These rare congenital nasal deformities result from embryological defects. Since 1906, Lindsay (Trans Pathol Soc Lond. 57:329-330, 1906) has published the first research of bilateral supernumerary nostrils, and only 34 cases have been reported so far in the English lite...

BACKGROUND This pharmacokinetic (PK) study was designed to investigate the maximum intranasal insulin dose that could be achieved by repeated doses in a single nostril of a nasal spray of recombinant regular human insulin 1% in combination with cyclopentadecalactone (CPE-215) 2%, a compound that enhances absorption of molecules across mucous membranes (Nasulin™, CPEX Pharmaceuticals, Inc.). M...

A new study has found that when a shark turns towards an odor, its directional decision is based on inter-nostril differences in odorant time of arrival, rather than on inter-nostril differences in odorant concentration.

Method 4022 patients (>=12 years old) were randomized into 4, 14-day double-blind, placebo-controlled SAR trials to receive MP29-02*, AZE, FP or placebo nasal sprays (all given as 1 spray/nostril bid). 612 patients (>=12 years old) were randomized into a 1-year, open-label, active-controlled, parallel-group chronic rhinitis trial to receive MP29-02* (1 spray/nostril bid) or FP nasal spray (2 sp...

A large body of evidence has shown that pigeons rely on an olfactory-based navigational map when homing from unfamiliar locations. Previous studies on pigeons released with one nostril occluded highlighted an asymmetry in favour of the right nostril, particularly concerning the initial orientation performance of naïve birds. Nevertheless, all pigeons experiencing only unilateral olfactory input...
