RESUMO
OBJECTIVE: To evaluate the association between consolidation on chest radiograph and typical bacterial etiology of childhood community acquired pneumonia (CAP) in the Etiology of Pneumonia in the Community study. STUDY DESIGN: Hospitalized children <18 years of age with CAP enrolled in the Etiology of Pneumonia in the Community study at 3 children's hospitals between January 2010 and June 2012 were included. Testing of blood and respiratory specimens used multiple modalities to identify typical and atypical bacterial, or viral infection. Study radiologists classified chest radiographs (consolidation, other infiltrates [interstitial and/or alveolar], pleural effusion) using modified World Health Organization pneumonia criteria. Infiltrate patterns were compared according to etiology of CAP. RESULTS: Among 2212 children, there were 1302 (59%) with consolidation with or without other infiltrates, 910 (41%) with other infiltrates, and 296 (13%) with pleural effusion. In 1795 children, at least 1 pathogen was detected. Among these patients, consolidation (74%) was the most frequently observed pattern (74% in typical bacterial CAP, 58% in atypical bacterial CAP, and 54% in viral CAP). Positive and negative predictive values of consolidation for typical bacterial CAP were 12% (95% CI 10%-15%) and 96% (95% CI 95%-97%) respectively. In a multivariable model, typical bacterial CAP was associated with pleural effusion (OR 7.3, 95% CI 4.7-11.2) and white blood cell ≥15 000/mL (OR 3.2, 95% CI 2.2-4.9), and absence of wheeze (OR 0.5, 95% CI 0.3-0.8) or viral detection (OR 0.2, 95% CI 0.1-0.4). CONCLUSIONS: Consolidation predicted typical bacterial CAP poorly, but its absence made typical bacterial CAP unlikely. Pleural effusion was the best predictor of typical bacterial infection, but too uncommon to aid etiology prediction.

Retinol binding protein and vitamin D were measured in children aged <5 years hospitalized with lower respiratory tract infection and respiratory syncytial virus and/or human metapneumovirus detections. Low vitamin levels were observed in 50% of the children and were associated with significantly elevated risk of the need for intensive care unit admission and invasive mechanical ventilation.

OBJECTIVE: To describe and compare the clinical characteristics, outcomes, and etiology of pneumonia among children hospitalized with community-acquired pneumonia (CAP) with neurologic disorders, non-neurologic underlying conditions, and no underlying conditions. STUDY DESIGN: Children <18 years old hospitalized with clinical and radiographic CAP were enrolled at 3 US children's hospitals. Neurologic disorders included cerebral palsy, developmental delay, Down syndrome, epilepsy, non-Down syndrome chromosomal abnormalities, and spinal cord abnormalities. We compared the epidemiology, etiology, and clinical outcomes of CAP in children with neurologic disorders with those with non-neurologic underlying conditions, and those with no underlying conditions using bivariate, age-stratified, and multivariate logistic regression analyses. RESULTS: From January 2010-June 2012, 2358 children with radiographically confirmed CAP were enrolled; 280 (11.9%) had a neurologic disorder (52.1% of these individuals also had non-neurologic underlying conditions), 934 (39.6%) had non-neurologic underlying conditions only, and 1144 (48.5%) had no underlying conditions. Children with neurologic disorders were older and more likely to require intensive care unit (ICU) admission than children with non-neurologic underlying conditions and children with no underlying conditions; similar proportions were mechanically ventilated. In age-stratified analysis, children with neurologic disorders were less likely to have a pathogen detected than children with non-neurologic underlying conditions. In multivariate analysis, having a neurologic disorder was associated with ICU admission for children ≥2 years of age. CONCLUSIONS: Children with neurologic disorders hospitalized with CAP were less likely to have a pathogen detected and more likely to be admitted to the ICU than children without neurologic disorders.

OBJECTIVE: To assess the relationship between secondhand smoke (SHS) exposure and disease severity among children hospitalized with community-acquired pneumonia (CAP). STUDY DESIGN: Children hospitalized with clinical and radiographic CAP were enrolled between January 1, 2010, and June 30, 2012 at 3 hospitals in Tennessee and Utah as part of the Centers for Disease Control and Prevention's Etiology of Pneumonia in the Community study. Household SHS exposure was defined based on the number of smokers in the child's home. Outcomes included hospital length of stay, intensive care unit admission, and mechanical ventilation. Proportional hazards and logistic regression models were used to assess associations between SHS exposure and outcomes. All models were adjusted for age, sex, race/ethnicity, household education level, government insurance, comorbidities, enrollment site, year, and season. RESULTS: Of the 2219 children included in the study, SHS exposure was reported in 785 (35.4%), including 325 (14.8%) with ≥2 smokers in the home. Compared with nonexposed children, the children exposed to ≥2 smokers had longer length of stay (median, 70.4 hours vs 64.4 hours; adjusted hazard ratio, 0.85; 95% CI, 0.75-0.97) and were more likely to receive intensive care (25.2% vs 20.9%; aOR, 1.44; 95% CI, 1.05-1.96), but not mechanical ventilation. Outcomes in children exposed to only 1 household smoker were similar to those in nonexposed children. CONCLUSION: Children hospitalized with CAP from households with ≥2 smokers had a longer length of stay and were more likely to require intensive care compared with children from households with no smokers, suggesting that they experienced greater pneumonia severity.

OBJECTIVE: The lack of well-trained, dedicated infection control personnel prevents optimal control of nosocomial infections in Latin American pediatric oncology centers. We collaboratively planned and implemented a multinational training course in San Salvador, El Salvador, to address this need. METHODS: The course relied on its organizers' experience in training international healthcare providers, the availability of the International Training Center for Nurses, previous infection control collaboration with the Hospital Nacional de Ninos Benjamin Bloom, and resources available at the University of El Salvador. The 4-week course consisted of lecture sessions combined with practical laboratory and hospital experience. RESULTS: Two courses, one conducted in 2005 and one in 2006, trained 44 professionals from 15 Latin American countries. Evaluations showed that course content and teacher performance met the trainees' needs and that all trainees acquired the necessary knowledge and skills. CONCLUSIONS: The course met the need for the training of Latin American infection control practitioners. Our experience can serve as a model for other organizations interested in strengthening infection control and prevention at international sites.
