This study sought to determine whether improvements in the care of children with congenital heart disease (CHD) have changed the epidemiology of infective endocarditis (IE). A retrospective study of patients 18 years of age and younger treated for IE from 1992 to 2004 (era 3) was conducted at the authors' children's hospital in New York City. This study was compared with two previous studies conducted at the same hospital from 1930 to 1959 (era 1) and from 1977 to 1992 (era 2). During the three eras, IE was diagnosed for 205 children with a median age of 8 years during eras 1 and 2, which decreased to 1.5 years during era 3, partly because of IE after cardiac surgery for young infants. In era 3, nonstreptococcal and nonstaphylococcal pathogens associated with hospital-acquired IE increased. Complications from IE declined during era 3, but after the widespread availability of antibiotics in 1944, crude mortality rates were similar in eras 1 (32%), 2 (21%), and 3 (24%). However, in era 3, mortality occurred only among subjects with hospitalacquired IE. The epidemiology of pediatric IE has changed in the modern era.

Pediatric IE remains associated with high crude mortality rates when it is acquired in the hospital. KeywordsCongenital heart disease; Endocarditis; Pediatrics Infective endocarditis (IE) in children is relatively rare but causes significant morbidity and mortality when it occurs. Several case series have demonstrated that the epidemiology of pediatric IE has changed in parallel with advances in medical care [1,2,12,15,20,25,34]. As the incidence of rheumatic fever has declined in developed countries due to reduction in overcrowded living conditions and improvements in diagnosis and care of pharyngitis caused by group A streptococci [26,28], the importance of rheumatic heart disease as an underlying risk factor for pediatric IE has substantially decreased. Surgical advances for children with congenital heart disease (CHD), including the introduction of bioprosthetic or synthetic materials, have improved the outcomes and life expectancy of such children, thereby increasing the number of children at risk for IE [2,9,18].The increased use of central venous catheters (CVCs) among hospitalized children, including premature infants, also has expanded the pediatric population at risk for IE [18]. Finally, the escalating complexity of hospitalized patients coupled with the use of broadspectrum antibiotics has led to the emergence of multidrug-resistant organisms causing hospital-acquired endocarditis [17,18].Our children's hospital serves as a referral center for infants and children with CHD. Two previous case series have described the epidemiolo...
While antifungal use at our hospital increased, candidemia rates remained stable. C. parapsilosis was the most common species but other non-C. albicans species increased during the study period. Local epidemiology should be monitored in pediatric populations for potential impact on management strategies.
Susceptibility (18 antimicrobial agents including high-dose tobramycin) and checkerboard synergy (23 combinations) studies were performed for 2,621 strains of Burkholderia cepacia complex isolated from 1,257 cystic fibrosis patients. Minocycline, meropenem, and ceftazidime were the most active, inhibiting 38%, 26%, and 23% of strains, respectively. Synergy was rarely noted (range, 1% to 15% of strains per antibiotic combination).
Strategies to reduce barriers to adherence to CF infection control guidelines are needed. Strategies could include quality improvement initiatives with enhanced education and skills workshops, sharing successful interventions among CF centers, and linking adherence to improved patient outcomes.
Surveillance for acute respiratory infection (ARI) and influenza-like illness (ILI) relies primarily on reports of medically attended illness. Community surveillance could mitigate delays in reporting, allow for timely collection of respiratory tract samples, and characterize cases of non–medically attended ILI representing substantial personal and economic burden. Text messaging could be utilized to perform longitudinal ILI surveillance in a community-based sample but has not been assessed. We recruited 161 households (789 people) in New York City for a study of mobile ARI/ILI surveillance, and selected reporters received text messages twice weekly inquiring whether anyone in the household was ill. Home visits were conducted to obtain nasal swabs from persons with ARI/ILI. Participants were primarily female, Latino, and publicly insured. During the 44-week period from December 2012 through September 2013, 11,282 text messages were sent. In responses to 8,250 (73.1%) messages, a household reported either that someone was ill or no one was ill; 88.9% of responses were received within 4 hours. Swabs were obtained for 361 of 363 reported ARI/ILI episodes. The median time from symptom onset to nasal swab was 2 days; 65.4% of samples were positive for a respiratory pathogen by reverse-transcriptase polymerase chain reaction. In summary, text messaging promoted rapid ARI/ILI reporting and specimen collection and could represent a promising approach to timely, community-based surveillance.
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.
