Streptococcus pneumoniae, type 23F, resistant to penicillin (MIC, 2 micrograms/mL) and multiple other antimicrobic agents, was isolated from middle ear fluid of a child with otitis media attending a day care center in Ohio. To determine the extent of spread of this strain, nasopharyngeal culture surveys were done, and 52 carriers were identified among 250 children attending the index day care center. No carriers were found among 121 children at two other day care centers in the same urban area. Use of prophylactic doses of antibiotics (P < .001) and frequent use of antibiotics (P < 0.001) were risk factors for nasopharyngeal carriage. Carriers were more likely to have had frequent otitis media episodes (P < .02) and otitis media not responsive to antimicrobial therapy (P < .001). Strategies to limit the spread of highly resistant pneumococcal strains should include encouraging judicious use of antimicrobic agents and reevaluating indications for prophylactic use of antimicrobic agents.
To clarify presentations, organisms, and locations of deep neck abscesses in children.Design: Retrospective review.Setting: Tertiary children's hospital. The study population comprised 169 patients younger than 19 years who were surgically treated for deep neck abscesses between 1989 and 1999.Main Outcome Measure: Resolution of abscess.Results: Neck mass (91%), fever (86%), cervical adenopathy (83%), poor oral intake (66%), and neck stiffness (59%) were common in all ages. Patients younger than 4 years, compared with patients 4 years or older, presented with agitation (50% vs 14%), cough (35% vs 14%), drooling (27% vs 12%), lethargy (46% vs 33%), oropharyngeal abnormalities (45% vs 60%), respiratory distress (5% vs 2%), retractions (5% vs 2%), rhinorrhea (53% vs 15%), stridor (4% vs 2%), and trismus (14% vs 53%). Children younger than 1 year were infected with Staphylococcus aureus (79%) vs group A streptococcus (6%). Children 1 year or older were infected with group A streptococcus (29%) vs S aureus (16%). Retropharyngeal or parapharyngeal regions were involved in children 1 year or older (49%) vs younger than 1 year (21%). Anterior or posterior triangles and submandibular or submental regions were involved in 39% and 36%, respectively, of children younger than 1 year vs 30% and 23%, respectively, of children 1 year or older. Retropharyngeal and parapharyngeal abscesses yielded group A streptococcus (34%) vs S aureus (11%). Anterior and posterior triangle abscesses yielded S aureus (35%) vs group A streptococcus (19%), as did submandibular and submental abscesses (42% vs 19%).Conclusions: Abscesses in children younger than 1 year affected anterior or posterior triangles and submandibular or submental regions, yielding S aureus. Abscesses in children 1 year or older affected retropharyngeal or parapharyngeal regions, yielding group A streptococcus.
The VEMP has characteristics that differentiate it from the postauricular response and the Jaw reflex. The VEMPs were dominant on the side ipsilateral to the stimulated ear. The overall morphology of the neonatal VEMP is quite similar to that of adults. The major neonatal differences are a shorter latency of the n23 peak and higher amplitude variability. Our results suggest that recording of the VEMP in neonates with various audio-vestibular problems provides useful information about vestibular function in this population and may provide information that leads to better care and rehabilitation for neonates at risk of developmental and motor system delay.
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.
