Despite the fact that naphthalene (NA), a volatile, ubiquitous air pollutant, was recently identified as a probable human carcinogen, little is known about nasal cytotoxicity from inhaled NA. To define and compare acute nasal injury from inhalation and systemic NA exposures, male Sprague-Dawley rats were exposed to filtered air; 3.4 or 23.8 ppm NA by inhalation for 4 h; or to 0, 25, 50, 100, or...

OBJECTIVE To analyze the incidence of early-onset nasal injury in infants with very low birth weight and indication for noninvasive ventilation via nasal prongs. METHODS A prospective case series of infants with gestational age <37 weeks, weight <1.500 g and postnatal age <29 days. The patients were evaluated three times daily from the installation of nasal prongs to the 3rd day of use. The p...

OBJECTIVES To find if the presence of epistaxis after nasal trauma can be used to predict post-traumatic external nasal deformity or a symptomatic deviated nasal septum. METHODS Retrospective analysis of all patients seen in the fractured nose clinic by the first author between 17 October 2003 and 27 February 2004. Presence of epistaxis, newly developed external nasal deformity, and the prese...

The nasal cavity is susceptible to chemically induced injury as a result of exposure to inhaled irritants. Some responses of the nasal mucosa to inhaled toxicants are species specific. These species-related differences in response may be due to variations in structural, physiologic, and biochemical factors, such as gross nasal cavity structure, distribution of luminal epithelial cell population...

BACKGROUND In critically ill patients, clinicians can have difficulty obtaining accurate oximetry measurements. OBJECTIVE To compare the accuracy of nasal alar and forehead sensor measurements and incidence of pressure injury. METHODS 43 patients had forehead and nasal alar sensors applied. Arterial samples were obtained at 0, 24, and 120 hours. Oxygen saturations measured by co-oximetry we...

OBJECTIVE To assess the incidence and risk factors associated with nasal septum injury in premature infants using reused and new nasal prongs. METHOD The study was a cohort from an open therapeutic intervention. The sample included 70 infants with a gestational age inferior to 37 weeks, who used nasal prongs and were hospitalized at the neonatal service of a hospital in Recife-PE, in the Nort...

We conducted this study to investigate the efficacy of the silicon gel application on the nares in prevention of nasal injury in preterm infants ventilated with nasal continuous positive airway pressure (NCPAP). Patients (n=179) were randomized into two groups: Group 1 (n=87) had no silicon gel applied to nares, and in Group 2 (n=92), the silicon gel sheeting was used on the surface of nares du...

Dear Editors, We present a case of nasal injury secondary to nasal continuous positive airway pressure in a 28-week-preterm infant, hospitalised in the neonatal intensive care unit of our hospital. After having applied a nasal continuous positive airway pressure (NCPAP) device at 4 weeks of birth, the infant showed a loss of cutaneous substance at the level of nasal columella with partial expos...
