RESUMEN
KEY FINDINGS: Data from the National Health and Nutrition Examination Survey, 1999-2010. From 1999 to 2010, the percentage of children without asthma exposed to environmental tobacco smoke (ETS) decreased from 57.3% to 44.2%, while children with asthma showed no change, with 57.9% exposed to ETS in 1999-2002 and 54.0% exposed in 2007-2010. In 2007-2010, a higher percentage of children with asthma were exposed to ETS than children without asthma. In 2007-2010, children with asthma were more likely to be exposed to ETS than children without asthma, if they were girls, Mexican American, aged 6-11 years, or had family income below 350% of the federal poverty guidelines.

BACKGROUND: The association between obesity and asthma severity and control in children is not well understood. OBJECTIVE: The objective of this study was to examine the association of childhood body mass index (BMI) percentile for age of 85% or greater with the number of ß-agonist canisters dispensed, corticosteroid courses, emergency department visits, and hospitalizations for asthma. METHODS: A retrospective cohort of 32,321 children aged 5 to 17 years and given a diagnosis of asthma who received at least 1 asthma (controller or rescue) medication and were enrolled in Kaiser Permanente from 2004-2008 was identified. Outcomes from electronic medical records included ß-agonist canister and nebulizer units dispensed per year, hospitalizations and emergency department visits for asthma exacerbations, and oral corticosteroid courses. Potential confounding factors known to influence asthma outcomes were also collected: demographics, parental education level, asthma controller use, gastroesophageal reflux disease diagnosis, and diabetes mellitus diagnosis. Multiple logistic regression models were used to measure the independent association of BMI status with outcomes. RESULTS: Even after adjusting for demographics, parental education level, asthma controller use, and gastroesophageal reflux disease and diabetes mellitus diagnoses, overweight (BMI percentile for age, 85% to 94%) and obese (BMI percentile for age, ≥ 95%) children were more likely to have increased ß-agonists dispensed (odds ratio of 1.15 [95% CI, 1.02-1.27] and odds ratio of 1.17 [95% CI, 1.06-1.29], respectively) and increased risk for oral corticosteroids dispensed (odds ratio of 1.21 [95% CI, 1.13-1.29] and odds ratio of 1.28 [95% CI, 1.21-1.36], respectively) compared with normal-weight (BMI percentile for age, 16% to 84%) children. CONCLUSIONS: Our findings suggest that childhood obesity is associated with an increased risk of worse asthma control and exacerbations.

INTRODUCTION: Recent adult reports have demonstrated sub-optimal performance of basic cardiopulmonary resuscitation (CPR) skills in advanced training scenarios and real life arrest situations. We studied the adequacy of chest compressions performed by advanced trained pediatric providers in code scenarios. METHODS: We designed a prospective observational study of pediatric providers performing external closed-chest compressions on a child mannequin that is designed to assess adequacy based on depth and rate of chest compressions. The study was conducted from 2008 to 2009 in which 42 subjects were screened and enrolled for participation. Each subject underwent a basic life support scenario that included two minutes of uninterrupted external closed-chest compressions that were assessed for adequacy based on depth and rate. RESULTS: For 42 subjects, 168 total 30-s time segments were available for analysis. Chest compressions were performed at a median rate of 110 (interquartile range (IQR) of 75-145) compressions per minute (cpm). No significant decay in rate of chest compressions was noted over the two-minute evaluation. Chest compression depth was adequate in 9.4% of total delivered chest compressions. No statistical significance was found on the job exposure to CPR and delivery of effective chest compressions. CONCLUSION: Advanced training of pediatric providers does not ensure adequate delivery of chest compressions. Rate standards and adequate depth of chest compressions are infrequently achieved and both may need more emphasis in CPR training and attention during resuscitations.

OBJECTIVE: To determine the incidence of vasospasm in children who have suffered moderate to severe traumatic brain injury. METHODS: A prospective observational pilot study in a 24-bed pediatric intensive care unit was performed. Twenty-two children aged 7 months to 14 years with moderate to severe traumatic brain injury as indicated by Glasgow Coma Score =12 and abnormal head imaging were enrolled. Transcranial Doppler ultrasound was performed to identify and follow vasospasm. Patients with a flow velocity in the middle cerebral artery (MCA) >120 cm/s were considered to have vasospasm by criterion A. If flow velocity in the MCA was >120 cm/s and the Lindegaard ratio was >3, vasospasm was considered to be present by criterion B. Patients with basilar artery (BA) flow velocity >90 cm/s met criteria for vasospasm in the posterior circulation (criterion C). RESULTS: In the MCA, 45.5% of patients developed vasospasm based on criterion A and 36.3% developed vasospasm based on criterion B. A total of 18.2% of patients developed vasospasm in the BA by criterion C. Typical day of onset of vasospasm was hospital day 2-3. Duration of vasospasm in the anterior circulation was 4 +/- 2 days based on criteria A and 3 +/- 1 days based on criteria B. Vasospasm in the posterior circulation persisted for 2 +/- 1 days. CONCLUSIONS: Using the adult criteria outlined above to diagnose vasospasm, a significant proportion of pediatric patients who have suffered moderate to severe traumatic brain injury develop vasospasm during the course of their treatment.
