Acute otitis media and otitis media with effusion (OME) are the main causes of hearing impairment in children which require proper treatment, mainly antibiotic therapy. Patients whom were appropriate candidates for adenoidectomy were divided into two groups regarding the presence of middle ear effusion. Adenoid tissue specimens were cultured in both groups and the bacterial flora and anti-microbial resistance pattern were determined. 72 patients were studied, 42 % had OME while 58 % did not. The following bacteria were isolated and cultured from both groups with no meaningful difference in prevalence: Streptococcus viridans (p = 0.265), Staphylococcus aureus (p = 0.72), H. influenza (p = 0.806), Entrococcus. spp (0.391), Streptococcus pneumonia (p = 0.391), nonhemolytic Streptococcus (p = 0.230). Bacterial sensitivity was similar for Amoxicillin-clavulanate (p = 0.935), Amoxicillin (p = 0.935), Cephalexin (p = 0.806), Cefixime (p = 0.391) and Azithromycin in both groups. The two groups showed no meaningful difference considering the bacterial flora of nasopharynx and their sensitivity. Bacteria in both groups were sensitive to Amoxicillin and Amoxicillin-clavulanate and resistant to Azithromycin, Cefixime and Cephalexin.
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.
