Artist Alien Ghost Juggler: Performance of “Troilus and Cressida” as Graduate Thesis

Through an analysis of my adaptation of Shakespeare’s “Troilus and Cressida”, I will deconstruct the artist’s studio within an institution as a paradoxical heterotopic space

Association of procalcitonin with acute pyelonephritis and renal scars in pediatric UTI.

Procalcitonin was a more robust predictor compared with C-reactive protein or white blood cell count for selectively identifying children who had APN during the early stages of UTI, as well as those with late scarring

Procalcitonin to reduce the number of unnecessary cystographies in children with a urinary tract infection: A European Validation Study

Objective To validate high serum procalcitonin (PCT) as a predictor of vesicoureteral reflux (VUR) in children with a first febrile urinary tract infection (UTI). Study design This secondary analysis of prospective hospital-based cohort studies included children ages 1 month to 4 years with a first febrile UTI. Results Of the 398 patients included in 8 centers in 7 European countries, 25% had VUR. The median PCT concentration,vas significantly higher in children with VUR than in those without: 1.6 versus 0.7 ng/ml, (P = 10(-4)). High PCT (>= 0.5 ng/ml) was' associated with VUR (OR: 2.3. 95% Cl, 1.3 to 3.9; P = 10(-3)). After adjustment for all cofactors, the association remained significant (OR: 2.5: 95% Cl, 1.4 to 4.4; P = 10(-3)). The strength of the relation increased with tire grade of reflux (P = 10(-5).). The sensitivity of procalcitonin was 75% (95% Cl, 66 to 83) for all-grade VUR and 100% (95% Cl, 81 to 100) for grade >= 4 VUR. both with 43% specificity (95% Cl, 37 to 48). Conclusions High PCT is a strong, independent and now validated predictor of VUR that can be used to identify low-risk patients and thus avoid one third of the unnecessary cystourethrographies in children with a first febrile UTI

Procalcitonin is a predictor for high-grade vesicoureteral reflux in children: Meta-analysis of individual patient data

Objective: To assess the predictive value of procalcitonin, a serum inflammatory marker, in the identification of children with first urinary tract infection (UTI) who might have high-grade (≥3) vesicoureteral reflux (VUR). Study design: We conducted a meta-analysis of individual data, including all series of children aged 1 month to 4 years with a first UTI, a procalcitonin (PCT) level measurement, cystograms, and an early dimercaptosuccinic acid scan. Results: Of the 152 relevant identified articles, 12 studies representing 526 patients (10% with VUR ≥3) were included. PCT level was associated with VUR ≥3 as a continuous (P =.001), and as a binary variable, with a 0.5 ng/mL preferred threshold (adjusted OR, 2.5; 95% CI, 1.1 to 5.4). The sensitivity of PCT ≥0.5 ng/mL was 83% (95% CI, 71 to 91) with 43% specificity rate (95% CI, 38 to 47). In the subgroup of children with a positive results on dimercaptosuccinic acid scan, PCT ≥0.5 ng/mL was also associated with high-grade VUR (adjusted OR, 4.8; 95% CI, 1.3 to 17.6). Conclusions: We confirmed that PCT is a sensitive and validated predictor strongly associated with VUR ≥3, regardless of the presence of early renal parenchymal involvement in children with a first UTI. © 2011 Mosby Inc.
