Intro: Transposition of the great arteries (TGA) is a rare cyanotic congenital heart defect (CHD) typically presenting the first month of life. Late presentations may occur in patients with associated cardiac anomalies allowing for mixing of oxygenated and deoxygenated blood, such as ventral septal defects or large atrial septal defects (ASD). We present a case of a late-presenting TGA with no ventral septal defect, and only small ASD and patent ductus arteriosus (PDA)., Case: A 2-month-old female infant presented to a rural emergency department with respiratory distress for 1 day. On arrival, she was cyanotic with only mild improvement in oxygen saturations on 15-L non-rebreather. Grade IV/VI murmur was noted, and prostaglandin E was started. She required intubation after becoming apneic and was transported to the local pediatric referral hospital. There, echocardiography showed dextro-type TGA, with 8-mm ASD with minimal gradient, small PDA with left to right flow, and ventral septal bowing. She underwent balloon septostomy and then atrial switch, which was well tolerated., Discussion: Our case is unique because of the patient's late presentation and prior lack of symptoms, given minimal levels of blood mixing though small ASD and PDA. Most TGA cases are now identified during prenatal ultrasound or with CHD screening pulse oximetry before discharge from the newborn nursery; however rare cases of late-presenting TGA may exist., Conclusion: Practitioners must maintain consideration of TGA, even after the newborn period, despite advances in newborn CHD screening in infants who present with new-onset respiratory distress without infection., Competing Interests: Disclosure: The authors have no potential conflicts of interest listed in the ICMJE.

Objective: Few prospective studies have assessed the occurrence of radiographic pneumonia in young febrile infants. We analyzed factors associated with radiographic pneumonias in febrile infants 60 days or younger evaluated in pediatric emergency departments., Study Design: We conducted a planned secondary analysis of a prospective cohort study within 26 emergency departments in a pediatric research network from 2008 to 2013. Febrile (≥38°C) infants 60 days or younger who received chest radiographs were included. Chest radiograph reports were categorized as "no," "possible," or "definite" pneumonia. We compared demographics, Yale Observation Scale scores (>10 implying ill appearance), laboratory markers, blood cultures, and viral testing among groups., Results: Of 4778 infants, 1724 (36.1%) had chest radiographs performed; 2.7% (n = 46) had definite pneumonias, and 3.9% (n = 67) had possible pneumonias. Patients with definite (13/46 [28.3%]) or possible (15/67 [22.7%]) pneumonias more frequently had Yale Observation Scale score >10 compared with those without pneumonias (210/1611 [13.2%], P = 0.002) in univariable and multivariable analyses. Median white blood cell count (WBC), absolute neutrophil count (ANC), and procalcitonin (PCT) were higher in the definite (WBC, 11.5 [interquartile range, 9.8-15.5]; ANC, 5.0 [3.2-7.6]; PCT, 0.4 [0.2-2.1]) versus no pneumonia (WBC, 10.0 [7.6-13.3]; ANC, 3.4 [2.1-5.4]; PCT, 0.2 [0.2-0.3]; WBC, P = 0.006; ANC, P = 0.002; PCT, P = 0.046) groups, but of unclear clinical significance. There were no cases of bacteremia in the definite pneumonia group. Viral infections were more frequent in groups with definite (25/38 [65.8%]) and possible (28/55 [50.9%]) pneumonias than no pneumonias (534/1185 [45.1%], P = 0.02)., Conclusions: Radiographic pneumonias were uncommon, often had viruses detected, and were associated with ill appearance, but few other predictors, in febrile infants 60 days or younger., Competing Interests: Disclosure: O.R. reports personal fees from HuMabs, Abbvie, Janssen, Medimmune, and Regeneron, and grants from Janssen.

Objective: Children evaluated in emergency departments for blunt head trauma (BHT) frequently undergo computed tomography (CT), with some requiring pharmacological sedation. Cranial CT sedation complications are understudied. The objective of this study was to document the frequency, type, and complications of pharmacological sedation for cranial CT in children., Methods: We prospectively enrolled children (younger than 18 years) with minor BHT presenting to 25 emergency departments from 2004 to 2006. Data collected included sedation agent and complications. We excluded patients with Glasgow Coma Scale scores of less than 14., Results: Of 57,030 eligible patients, 43,904 (77%) were enrolled in the parent study; 15,176 (35%) had CT scans performed or planned, and 527 (3%) received pharmacological sedation for CT. Sedated patients' characteristics were as follows: median age, 1.7 years (interquartile range, 1.1-2.5 years); male 61%; Glasgow Coma Scale score of 15, 86%; traumatic brain injury on CT, 8%. There were 488 patients (93%) who received 1 sedative. Sedation use (0%-21%) and regimen varied by site. Pentobarbital (n = 164) and chloral hydrate (n = 149) were the most frequently used agents. Sedation complications occurred in 49 patients (9%; 95% confidence interval [CI], 7%-12%): laryngospasm 1 (0.2%; 95% CI, 0%-1.1%), failed sedation 31 (6%; 95% CI, 4%-8%), vomiting 6 (1%; 95% CI, 0.4%-2%), hypotension 13 (4%; 95% CI, 2%-7%), and hypoxia 1 (0.2%; 95% CI, 0%-2%). No cases of apnea, aspiration, or reversal agent use occurred. One patient required intubation. Vomiting and failed sedation were most common with chloral hydrate., Conclusions: Pharmacological sedation is infrequently used for children with minor BHT undergoing CT, and complications are uncommon. The variability in sedation medications and frequency suggests a need for evidence-based guidelines.
