Objective: Protamine is used to neutralize heparin after patient separation from cardiopulmonary bypass (CPB). Different bedside tests are used to monitor the adequacy of heparin neutralization. For this study, the interchangeability of the activated coagulation time (ACT) and thromboelastometry (ROTEM; Tem Innovations GmbH, Basel, Switzerland) clotting time (CT) ratios in children undergoing cardiac surgery was assessed. Design: Single-center, retrospective, cohort study between September 2010 and January 2012. Setting: University children's hospital. Participants: The study comprised children 0 to 16 years old undergoing elective cardiac surgery with CPB. Exclusion criteria were preoperative coagulopathy, Jehovah's witnesses, and children in a moribund condition (American Society of Anesthesiologists score 5). Interventions: None. Measurements and Main Results: After heparin neutralization with protamine, the ratio between ACT, with and without heparinase, and the CT measured with INTEM/HEPTEM (intrinsic test activated with ellagic acid was performed without heparinase [INTEM] and with heparinase [HEPTEM]) using tests of ROTEM were calculated. Agreement was evaluated using Cohen's kappa statistics, Passing-Bablok regression, and Bland-Altman analysis. Among the 173 patients included for analysis, agreement between both tests showed a Cohen's kappa statistic of 0.06 (95% CI: -0.02 to 0.14; p = 0.22). Bland-Altman analysis showed a bias of 0.01, with a standard deviation of 0.13, and limits of agreement between -0.24 and 0.26. Passing-Bablok regression showed a systematic difference of 0.40 (95% CI: 0.16-0.59) and a proportional difference of 0.61 (95% CI: 0.42-0.86). The residual standard deviation was 0.11 (95% CI: -0.22 to 0.22), and the test for linearity showed p = 0.10. Conclusion: ACT, with or without heparinase, and the INTEM/HEPTEM CT ratios are not interchangeable to evaluate heparin reversal after pediatric patient separation from CPB. Therefore, the results of these tests should be corroborated with the absence/presence of bleeding and integrated into center-specific treatment algorithms. © 2016 Elsevier Inc.

Duodenal atresia is a common cause of neonatal obstruction. It is frequently associated with other malformations such as Down syndrome, cardiac anomalies, malrotation or annular pancreas. Double duodenal atresia is an exceptional malformation. There are only few publications on this subject and none are in association with “Cri du Chat” (Cat Cry) syndrome. We present a newborn, prenatally diagnosed with duodenal atresia and with “Cri du Chat” syndrome. The double duodenal atresia was actually of two different types (type I and type II), associated with malrotation. The second atresia was a peroperative finding at reintervention, five days later. We wish to share our experience in order to avoid unnecessary surgery and co-morbidities. © 2016 The Authors

OBJECTIVE: Our objective was to develop an easy, safe, pragmatic, clinical scoring system that would allow decreases in unnecessary treatment with antimicrobial agents in low-resource settings. METHODS: Children with pharyngitis were enrolled prospectively from 2 public hospitals and 1 medical unit in Brasilia, Brazil, over 17 months. Attending clinicians completed a questionnaire and a previously published scoring system for pharyngitis before performing throat swabs and group A streptococcus (GAS) rapid antigen-detection tests. Data from this study were added to those collected in 2004, to assess the performance of each item of the scoring system. The performance of the new clinical decision rule was determined with a receiver operating characteristic curve. The final outcome of the model was assessed on the basis of sensitivity, specificity, and positive likelihood ratio for non-GAS infections with the clinical approach, compared with throat culture or rapid antigen-detection test results. RESULTS: A total of 576 children were included, among whom 400 had non-GAS pharyngitis. The use of our new clinical decision rule would allow for 35% to 55% antibiotic reduction, with 88% specificity. CONCLUSIONS: This clinical decision rule could reduce unnecessary antibiotic treatment significantly in low-resource settings. Copyright © 2010 by the American Academy of Pediatrics.
