Children younger than 16 months and/or with lateral neck abscesses are at a significantly increased risk of having an SA infection, the majority being MRSA.
There is an alarming nationwide increase in the prevalence of pediatric methicillin-resistant S aureus head and neck infections. Disparities in the treatment of various head and neck infections nationwide may contribute to the regional differences in the prevalence of such infections. Judicious use of antibiotic agents and increased effectiveness in diagnosis and treatment are warranted to reduce further antimicrobial drug resistance in pediatric head and neck infections.
Our study shows a continuum of increasing pharyngeal reflux with higher LTH severity. Severe LTH may be a reliable physical sign of pharyngeal reflux, especially NPR.
To determine the sensitivity and specificity of airway fluoroscopy in the diagnosis of pediatric laryngotracheal abnormalities. Design: Retrospective chart review. Setting: Tertiary care children's hospital. Patients: Thirty-nine children, with a mean age of 18 months at the time of evaluation, were evaluated for stridor. Main Outcome Measures: Diagnoses made by airway fluoroscopy and endoscopy. The medical records of patients who had undergone both airway fluoroscopy and airway endoscopy for the evaluation of stridor over a 5-year period were reviewed. The sensitivity, specificity, and positive and negative predictive values of airway fluoroscopy in the diagnosis of laryngomalacia, tracheomalacia, airway stenosis at any level, and airway mass lesions were determined using endoscopic evaluation as the "gold standard." Results: Twenty-three of 39 patients (59%) received a different diagnosis by airway endoscopy than by airway fluoroscopy. The sensitivity of airway fluoroscopy in the diagnosis of laryngomalacia, tracheomalacia, airway stenosis, and an airway mass was 27%, 20%, 69%, and 43%, respectively. The specificity for the same diagnoses was 100%, 94%, 100%, and 100%, respectively. Conclusions: Airway fluoroscopy appears to be reliable in the diagnosis of laryngomalacia, tracheomalacia, airway stenosis, and airway masses because of its high specificity. However, its sensitivity in detecting these common causes of stridor is poor. Negative fluoroscopic study results require further diagnostic evaluation if the clinical indication exists; therefore, the value of fluoroscopy as a screening tool remains uncertain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
