BACKGROUND Acute otitis media (AOM) occurs as a complication of viral upper respiratory tract infections in young children. AOM and respiratory viruses both display seasonal variation. Our objective was to examine the temporal association between circulating respiratory viruses and the occurrence of pediatric ambulatory care visits for AOM. METHODS This(More)
BACKGROUND Pediatric pneumococcal parapneumonic empyema (PPE) has become increasingly common. In the last decade, Utah has had one of the highest rates of PPE in the United States, 14/100,000 children, attributed primarily to Streptococcus pneumoniae serotype 1. Our objective was to describe the temporal trends in PPE in Utah before and after the(More)
BACKGROUND Streptococcus pneumoniae is the most common cause of bacterial pneumonia in children. Despite the use of the 7-valent pneumococcal conjugate vaccine, the incidence of pneumococcal necrotizing pneumonia (PNP) has been increasing. Our objectives were to describe temporal trends in PNP and to evaluate pneumococcal serotypes associated with PNP in(More)
OBJECTIVE The objective of this study was to describe pregnancy outcomes, including cervical insufficiency and preterm birth, in the subsequent pregnancy following an intrapartum cervical laceration. STUDY DESIGN Retrospective cohort of women with their first two consecutive singleton pregnancies carried to ≥ 20(0/7) weeks' gestation within a tertiary(More)
Gordonia species are emerging pathogens that are often misidentified as Rhodococcus or Nocardia species but are reliably distinguished by 16S ribosomal RNA gene sequencing. We present a case series of 6 episodes of catheter-associated infection caused by Gordonia species in 5 patients seen at a tertiary care pediatric hospital and describe the management(More)
OBJECTIVE Our objective was to confirm an observed temporal association of increased numbers of rheumatic fever cases concomitant with the appearance of an increased prevalence of mucoid strains of Streptococcus pyogenes. During the resurgence of rheumatic fever (RF) that has occurred in the Intermountain area surrounding Salt Lake City, Utah, since 1985,(More)
A multicenter study was performed to evaluate the susceptibility of beta-hemolytic streptococci to nine antimicrobial agents. MICs were performed in cation-supplemented Mueller-Hinton broth with 3.5% lysed sheep red blood cells according to NCCLS guidelines. A total of 646 isolates were tested: 300 (46%) group A; 170 (26%) group B; 38 (6%) group C, 35 (5%)(More)
BACKGROUND Use of the heptavalent pneumococcal conjugate vaccine (PCV-7 [Prevnar]) has been associated with decreased a incidence of invasive pneumococcal disease (IPD) among children in the United States. METHODS Cases of IPD in children < 18 years of age insured by or receiving health care from Intermountain Health Care during 1996-2003 were identified.(More)
OBJECTIVE We evaluated the presentation, outcomes, and the risk of serious bacterial infection (SBI) in infants <3 months old with influenza virus infection. PATIENTS AND METHODS We identified demographic, hospitalization, and microbiologic data from computerized medical records for all infants and children <24 months of age, with laboratory confirmed(More)
OBJECTIVE Our objective was to demonstrate correlations between invasive pneumococcal disease in children and circulating respiratory viruses. METHODS This retrospective study included 6 winter respiratory viral seasons (2001-2007) in Intermountain Healthcare, an integrated health system in the Intermountain West, including Primary Children's Medical(More)
