Dysfunctional Elimination Syndrome: Is It Related to Urinary Tract Infection or Vesicoureteral Reflux Diagnosed Early in Life?

Objective. It has been suggested that urinary tract infections (UTIs) early in life predispose to dysfunctional elimination syndrome (DES). This study evaluated the relationship between early UTI, vesicoureteral reflux (VUR), and DES by comparing two cohorts of school-aged children. Methods. The UTI cohort (n = 123) included children previously enrolled in a prospective treatment trial conducted between 1992 and 1997. All were diagnosed with a febrile UTI before 2 years of age. The comparison cohort (n = 125) included children who were evaluated for fever in the emergency department between 1992 and 1997, whose urine culture was negative. Dysfunctional elimination symptoms were compared in the two cohorts by having families complete a revised version of the Dysfunctional Voiding Scoring System. Results. Completed questionnaires were received from 248 children. There were no significant differences in selected demographic or clinical characteristics between the two cohorts. DES was present in 22% and 21% of children with and without a history of early UTI, respectively. Among children with UTIs, 18% of those with VUR and 25% of those without VUR had DES. Conclusions. Dysfunctional elimination is common in a general pediatric population. Neither UTI nor VUR diagnosed before 2 years of age was associated with DES in school-aged children

Development of a patient-reported outcome measure for children with streptococcal pharyngitis

OBJECTIVE: The objective of this study was to develop a patient-reported outcome measure (Strep-PRO) for assessing symptoms of group A Streptococcus (GAS) pharyngitis from the child's point of view and to present preliminary data on its internal reliability, construct validity, and responsiveness. METHODS: We selected 8 symptoms for inclusion in the Strep-PRO. We used the Strep-PRO to assess improvement in children who were aged 5 to 15 years and had confirmed GAS pharyngitis. Children completed the scale at study visits and as a diary at home. To evaluate internal reliability, we examined correlations between the items on the scale. To evaluate construct validity, we examined the correlation at entry between Strep-PRO scores and scores on other, previously validated measures of pain and functional status. To evaluate responsiveness, we examined the change in score from enrollment to follow-up. The correlation between the Strep-PRO score and parental assessment of symptoms was also evaluated. RESULTS: A total of 131 children were enrolled; 113 returned completed diaries. The internal reliability of the scale was high. The magnitude of correlations between Strep-PRO scores and other measures of pain and functional status ranged from 0.39 to 0.63. The responsiveness of the Strep-PRO was very good. The overall level of agreement between child Strep-PRO scores and parental assessment of symptoms was 0.57. CONCLUSIONS: The scale seems to measure effectively both pain and overall functional status in children with GAS pharyngitis. These data support the use of Strep-PRO as a measure of outcome in future clinical trials. Copyright © 2009 by the American Academy of Pediatrics

Pneumococcal resistance and serotype 19a in Pittsburgh-area children with acute otitis media before and after introduction of 7-valent Pneumococcal polysaccharide vaccine

Methods: Before and after introduction of pneumococcal conjugate vaccine (PCV7), the authors obtained nasopharyngeal (NP) specimens from 3 groups of children aged 6 to 23 months with acute otitis media (AOM): group 1 (pre-PCV7), group 2 (early post-PCV7), and group 3 (late post-PCV7). Results: Of the Streptococcus pneumoniae isolates, the proportion that were vaccine serotypes (VTs) declined progressively (60.4% vs 48.6% vs 5.2% in groups 1, 2, and 3, respectively; P 0.1 μg/mL; 26.7% vs 37.8% vs. 38.5%; P =.12); the proportion of isolates that were serotype 19A (4.0% vs 0% vs 25.9%; P <.001); and the proportion of 19A isolates that were penicillin-nonsusceptible (0% in group 1, 68.6% in group 3; P =.004). Conclusion: Shifts in pneumococcal serotype distribution and increases in penicillin nonsusceptibility among pneumococcal isolates from children with AOM underscore the need for continuing bacteriological surveillance for future vaccine development. © The Author(s) 2011
