Prevalence of renal anomalies after urinary tract infections in hospitalized infants less than 2 months of age.
Repository Usage Stats
OBJECTIVE: Our aim was to determine the incidence of anatomical abnormalities after a urinary tract infection (UTI) in infants <2 months of age hospitalized in the neonatal intensive care unit (NICU). STUDY DESIGN: This was a retrospective, single-center cohort study of infants <2 months of age in the NICU with a UTI and documented renal imaging. RESULT: We identified 141 infants with UTIs. The mean gestational age and birth weight were 28 weeks and 1254 g, respectively. The most commonly identified pathogen was coagulase-negative Staphylococcus (28%, 44 of 156). A major abnormality was found on at least one imaging study for 4% (5 of 118) of infants. Major abnormalities were noted on 4% (5 of 114) of renal ultrasounds and 2% (2 of 82) of voiding cystourethrography examinations. CONCLUSION: Among infants in the NICU <2 months of age at the time of a UTI, the prevalence of major anatomical abnormalities is <5%.

I am involved in 4 major areas of research: 1) Neuroprotection. Working with colleagues from Cell Therapies, we have added to Duke's experience participating in pivotal trials of hypothermia for term newborns with moderate to severe hypoxic-ischemic encephalopathy (HIE) by completing a phase I study of autologous cord blood cells for these infants, and developing and currently leading a multicenter, double-blind randomized clinical trial of autologous cord blood cells or placebo in te

We are studying human microbial ecology and the molecular basis for different bacterial infections that are of relevance to both children and adults. Summaries of the research areas are described below: 1. THE MOLECULAR BASIS FOR VIRULENCE OF UROPATHOGENIC ESCHERICHIA COLI AND URINARY TRACT INFECTIONS. Uropathogenic Escherichia coli (UPEC) is the leading cause of community-acquired urinary tract infections (UTIs). Over 100 million UTIs occur annually throughout the world inclu
