Evaluation of Prevalence of S. pneumoniae pharyngeal carriers under 5 years of age by lytA gene detection
ABSTRACT Background and Objective: Streptococcus pneumoniae is one of the leading causes of death among children worldwide. Nasopharyngeal colonization in children can spread pneumococcal infections in the community. This study aimed to evaluate the prevalence of S. pneumoniae strains isolated from healthy pharyngeal carriers less than 5 yea...
متن کاملPharyngeal Airway: An Analysis Using 2D vs. 3D Images in Different Malocclusions
Introdouction: The aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3D) cone-beam computed tomography (CBCT) scans. Materials and methods: In this prospective cross-sectional study, CBCT scans and lateral cephalograms of 35 subjects, taken with...
متن کاملTest-retest validity of acoustic pharyngometry measurements.
BACKGROUND Acoustic reflectometry is a relatively new technique that quantifies upper airway obstruction. The oropharyngeal airway is geometrically complex and variable; therefore establishing a standard operating protocol and understanding the possible sources of artifacts are of great importance in obtaining reliable results. This work aims at assessing the repeatability of pharyngeal cross-s...
متن کاملProtected specimen brush in the assessment of ventilator-associated pneumonia. Selection of a certain lung segment for bronchoscopic sampling is unnecessary.
The protected specimen brush (PSB) with quantitative cultures is one of the most reliable techniques for assessing pneumonia in mechanically ventilated (MV) patients. The need to select a certain lung segment for bronchoscopic sampling is still debated. We investigated whether the results of PSB specimens collected within an area radiographically involved with pneumonia (inv-PSB) differed from ...
متن کاملAcoustic pharyngometry patterns of snoring and obstructive sleep apnea patients.
OBJECTIVE Anatomic narrowing of the pharyngeal airway increases the relative negative pressure generated during inspiration, thus affecting the dynamic behavior of the upper airway. The aim of this work was to measure pharyngeal area in snoring patients with and without obstructive sleep apnea (OSA), as categorized by polysomnography and by acoustic pharyngometry, and to analyze the different c...
