on passing a probe through this hole it was found to be quite a separate passage opening into the rnaiB urethra about 1A inches above the meatus, from whic^ it was separated by a thin septum. It appeared that the septum was united above with the roof of tk? urethra and did not allow the passage of urine through the meatus. On the previous day, it was the septic* which had offered resistance to ...

Electron microscopic studies of bovine nasal cartilage proteoglycans have been carried out to examine the hypothesis that the size of a proteoglycan subunit is determined mainly by the length of the chondroitin sulfate-rich region of proteoglycan subunit core protein. A polydisperse population of proteoglycan subunits f rom ma tu re bovine nasal cartilage was separated into a series of relative...

OBJECTIVE To propose Irish CT diagnostic reference levels (DRLs) by collecting radiation doses for the most commonly performed CT examinations. METHODS A pilot study investigated the most frequent CT examinations. 40 CT sites were then asked to complete a survey booklet to allow the recording of CT parameters for each of 9 CT examinations during a 12-week period. Dose data [CT volume index (C...

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...

BACKGROUND Asians with short nose lack the cartilage needed to extend the length of the nose. A rhinoplasty technique using lower lateral cartilage (LLC) repositioning and ear cartilage grafting allows for sufficient nasal lengthening and nasal tip mobility in the correction of short nose in Asians. METHODS Short nose was classified into 3 subtypes: type I, II, or III. During LLC repositionin...

This study investigates the perception of the German coda nasal contrast /n/-/m/-/ŋ/ by Japanese learners of German compared to German native speakers. The phonological distribution of coda nasals differs with/without word boundaries in the two languages. Word final coda before a pause in Japanese is neutralized to /ɴ/ but the place feature remains in German. Assimilation of coda nasals before ...

BACKGROUND Nasal non-invasive-ventilation (Nasal NIV) is a mode of ventilatory support providing positive pressure to patients via a nasal interface. The RAM Cannula is an oxygen delivery device that can be used as an alternative approach to deliver positive pressure. Together they have been successfully used to provide respiratory support in neonatal in-patient settings. OBJECTIVE To describ...

BACKGROUND Tip-plasty is a particularly challenging stage of aesthetic nose surgery. The diversity of nasal tip deformities has necessitated the development of numerous surgical techniques that can be difficult to master and may yield unpredictable surgical results when combined. OBJECTIVES The authors describe how concomitant overlap steal tip-plasty (COST) can enable surgeons to address all...

Nasal mucociliary clearance is one of the most important factors affecting nasal delivery of drugs and vaccines. This is also the most important physiological defense mechanism inside the nasal cavity. It removes inhaled (and delivered) particles, microbes and substances trapped in the mucus. Almost all inhaled particles are trapped in the mucus carpet and transported with a rate of 8-10 mm/h t...

The aim of this study was to investigate the prevalence and factors associated with nasal septum injury in preterm infants in the use of noninvasive ventilation. A cross-sectional study with data collection between March and July 2012 and with search for records, interviews with mothers and nasal evaluation of 47 premature in the neonatal unit of a teaching hospital in Recife, Pernambuco, north...
