Before the introduction of conjugate pneumococcal vaccines and routine penicillin prophylaxis, febrile patients with sickle cell disease were known to have a 3% to 5% risk of bacteremia. Consequently, hospitalization rates for febrile episodes are >70%.

We observed no mortality or morbidity among those managed completely as outpatients, and bacteremia occurred in <1%. Physicians should strongly consider outpatient management of febrile children with sickle cell disease if there are no other indications for admission. (Read the full article)

Blood lead levels well below 10 µg/dL are now recognized as causing adverse cognitive effects, including lower scores on standardized reading and math tests.

This is the first study to show that reading readiness early in kindergarten is independently associated with blood lead levels well below 10 µg/dL. Results suggest that lead exposure may have a larger impact on urban education than national estimates suggest. (Read the full article)

Public health policy focuses on reducing formula use for breastfed infants during the birth hospitalization. Observational evidence supports this approach, but no previous studies have examined the effect of early use of small volumes of formula on eventual breastfeeding duration.

Use of limited volumes of formula during the birth hospitalization may improve breastfeeding duration for newborns with high early weight loss. Reducing the use of formula during the birth hospitalization could be detrimental for some subpopulations of healthy term newborns. (Read the full article)

Universal oxygen saturation screening by pulse oximetry is now recommended for early detection of critical congenital heart disease. The distribution of saturations in asymptomatic newborns in a large population has not been described.

Our study is the largest to date to establish simultaneous pre- and postductal oxygen saturation nomograms in asymptomatic newborns at ~24 hours after birth. The mean postductal saturation is higher than preductal during this time. (Read the full article)

Cross-sectional studies in children and adults have reported a significant positive association between attention-deficit/hyperactivity disorder (ADHD) and obesity.

This controlled, prospective, follow-up study of boys with ADHD found significantly higher BMI and obesity rates in adulthood, compared with men without childhood ADHD, regardless of socioeconomic status and other lifetime mental disorders. (Read the full article)

Routine head ultrasound scans (HUSs) are frequently performed in the preoperative evaluation of the infants with congenital heart disease, and brain MRI is being increasingly used in the research setting. The utility of HUSs in this population has not yet been established.

This is the first study to prospectively evaluate the utility of routine HUSs compared with MRIs in asymptomatic newborns and young infants undergoing cardiac surgery. Our findings suggest that routine HUS is not indicated in asymptomatic term or near-term neonates undergoing surgery for CHD. (Read the full article)

Many US children aged 6 to 24 months who would be classified as low weight-for-age by the Centers for Disease Control and Prevention 2000 reference will be classified as normal weight-for-age by the World Health Organization 2006 standard.

Children who will be reclassified from low to normal weight-for-age using the World Health Organization growth standard are at higher risk of adverse health outcomes than children who are not low weight-for-age by the Centers for Disease Control and Prevention reference. (Read the full article)

Sleep patterns of adult monozygotic twins are more similar than those of dizygotic twins, showing moderate heritability and little effects of environmental influences. There have been very few genetically informative studies of sleep in preschool children and results appear inconsistent.

From previous studies, we investigated daytime and nighttime continuous sleep duration longitudinally. This is the first time that the etiologies of daytime and nighttime continuous sleep duration trajectories were studied in early childhood. (Read the full article)

Introduction of the pneumococcal conjugate vaccine was associated with decreased invasive pneumococcal disease (IPD) in children. Few data exist on the impact in infants aged 1 to 90 days, who are too young to be fully immunized.

The incidence and proportion of IPD in Utah infants aged 1–90 days remained stable after vaccine introduction. IPD caused by PCV7 serotypes decreased significantly in the post-vaccine period. Serotype 7F emerged as the predominant serotype and commonly resulted in meningitis. (Read the full article)

Infants with birth defects are more likely to be born preterm or with low birth weight and are at higher risk of death.

This study describes the prevalence of birth defects in a cohort of very low birth weight infants and evaluates in-hospital surgical procedures, morbidity, and mortality. (Read the full article)

Infants born late-preterm and early-term are at higher risk of morbidity and mortality compared with term infants. Home care practices recommended for all infants include supine sleep position, no smoke exposure, and breastfeeding to optimize health outcomes.

Our study provides new findings on the timing of hospital discharge, outpatient follow-up, and home care of late-preterm and early-term infants compared with term infants in the United States. (Read the full article)

Randomized controlled trials have shown that zinc supplementation during diarrhea substantially reduces the incidence and severity. However, the effect of short-course prophylactic zinc supplementation has been observed only in children >12 months of age.

The current study was able to show that short-course prophylactic zinc supplementation significantly reduced diarrhea morbidity in apparently healthy infants of 6 to 11 months even after 5 months of follow-up. (Read the full article)

The incidence of permanent hearing loss doubles between birth and school age. Otoacoustic emissions screening has been used successfully in early childhood educational settings to identify children with losses not found through newborn screening.

Using otoacoustic emissions to screen the hearing of young children during routine health care visits is feasible and can lead to the identification of permanent hearing loss overlooked by providers relying solely on subjective methods. (Read the full article)

About one in five 2-year-olds are overweight, with potential adverse outcomes. Early feeding practices lay the foundation for food preferences and eating behavior and may contribute to future obesity risk. High-quality obesity prevention trials commencing in infancy are rare.

In this large randomized controlled trial, anticipatory guidance on the "when, what, and how" of complementary feeding was associated with increased maternal "protective" feeding practices. Differences in anthropometric indicators were in the expected direction but did not achieve statistical significance. (Read the full article)

Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few single-country reports are available describing delivery of primary care to children with obesity.

Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. (Read the full article)

Feeding difficulties often emerge during the neonatal period and affect neonatal growth. Growth throughout the first years of life is associated with children’s IQ scores and risk of behavioral problems.

Among infants born full term (≥37 weeks’ gestation) with birth weight ≥2500 g, gain in weight and head circumference during the neonatal period is associated with higher IQ, but not with behavior at 6.5 years of age. (Read the full article)

Coxsackievirus A6 (CVA6) was identified as an important cause of "severe" hand, foot, and mouth disease (HFMD) during the 2011–2012 outbreak in North America. The atypical cutaneous features in this outbreak have not been well documented.

The cutaneous manifestations of CVA6-associated HFMD may be more extensive and variable than classic HFMD. Four distinct morphologies characterize this exanthem: (1) widespread vesiculobullous and erosive lesions, (2) "eczema coxsackium," (3) an eruption similar to Gianotti-Crosti, and (4) purpuric lesions.

Popular press and research show that sibling aggression is common. Too often, however, it is dismissed as benign, and other forms of child aggression, such as peer aggression, are considered more serious. Peer aggression is linked to poorer mental health.

Using a national probability sample, we show that the nature and severity of sibling aggression have negative links to children’s and adolescents’ mental health. We demonstrate that sibling and peer aggression are comparable their links to symptoms of distress. (Read the full article)

Several studies have investigated the prevalence of chronic daily headache (CDH) and analyzed the risk factors for its persistence. However, the etiologic factors that lead to new-onset CDH remain unsettled in adolescents.

This study was the first incidence study of CDH conducted in young adolescents. We reported the incidence rates and found that some risk factors for incident chronic migraine and chronic tension-type headache were different. (Read the full article)

Obesity is associated with cardiometabolic risk factors and chronic conditions, such as type 2 diabetes. However, a proportion of overweight and obese youth remain free from cardiometabolic risk factors and are considered metabolically healthy.

This study provides insight into the determinants of cardiometabolic risk factors and the concept in health promotion of "fitness versus fatness." Hepatic lipid accumulation and not fitness level appears to drive cardiometabolic risk factor clustering among overweight and obese youth. (Read the full article)

Although unnecessary for children with headache and normal history, computed tomography (CT) scans are widely used. Fewer than 1% of pediatric brain abnormalities present with headache as the only symptom. Furthermore, repeated CT scans may increase lifetime risk of cancer.

CT scans continue to be used to diagnose isolated pediatric headaches despite existing practice parameters. Although emergency department visits were correlated with greater likelihood of CT scan use, these scans were widely used across a variety of clinical settings. (Read the full article)

Infants born late preterm and early term are at increased risk for short-term morbidities compared with term infants. Longer-term morbidity and disability in this group of infants is not well established.

Massachusetts infants born late preterm and early term are at increased risk of early intervention program enrollment than term infants. Boys and children whose mothers were less educated, older, and with public insurance were most affected. (Read the full article)

Child maltreatment is a serious and prevalent public health problem in the United States. Responsible for substantial morbidity and mortality, maltreatment affects children's physical and mental health.

Although many health impacts of child maltreatment have been documented, no claims-based study has quantified the impact of maltreatment on health service utilization and costs. This study presents systematic claims-based estimates of maltreatment impacts on utilization and costs for the Medicaid population. (Read the full article)

Cornelia de Lange syndrome (CdLS) is a genetic syndrome with multisystem abnormalities. Infections are a significant cause of morbidity and mortality in affected patients and are typically attributed to anatomic abnormalities.

This study identified a high frequency of antibody immunodeficiency in CdLS subjects, indicating a critical need for screening and management of immunodeficiency in CdLS patients with a history of severe or recurrent infections. (Read the full article)

Functional somatic symptoms (FSS) in children account for 10% to 15% of visits in medical services. Few studies have investigated the full range of pediatric FSS and factors linked to the medical help-seeking for young children with these symptoms.

More parental worries, higher symptom severity and impact, and previous contact to medical services are found among the children with FSS who seek medical consultation. Putative risk mechanisms include the early pattern of health care use and parental worries. (Read the full article)

Violence involving firearms is a leading cause of death among US youth ages 14 to 24. The emergency department is the primary medical setting for care of assault-injured youth and an underused but important setting for violence-prevention programs.

Among assault-injured youth seeking emergency department care, firearm possession rates are high, most obtained outside of legal channels. Higher rates of negative retaliatory attitudes and substance use among those youth with firearms increases risk of future lethal violence. (Read the full article)

Children exposed to alcohol prenatally have increased risk of a range of developmental problems such as language delay, behavior problems, learning, and memory and cognitive deficits, all of which can have a negative impact on educational achievement.

The expression of learning problems varied with the dose, pattern, and timing of prenatal alcohol exposure. Test scores below national benchmarks for reading were associated with first trimester heavy alcohol exposure and for writing after late pregnancy occasional binge drinking. (Read the full article)

Prenatal diagnosis and clinical examination do not identify all infants with critical congenital heart defects before hospital discharge. To improve early critical congenital heart defect detection, New Jersey was the first state to implement legislatively mandated newborn pulse oximetry screening.

This report is the first to evaluate statewide pulse oximetry screening implementation. New Jersey had a high statewide screening rate and identified 3 infants with previously unsuspected critical congenital heart defects that otherwise might have resulted in significant morbidity and mortality.

Brief periods of low oxygen saturation are common in infants while restrained in car safety seats. There is some evidence that an insert that allows the infant head to rest in a neutral position in sleep may reduce hypoxic episodes.

This randomized controlled study shows that the insert reduced numbers of obstructive apneas and the severity of desaturation events but did not significantly reduce the overall rate of moderate desaturations. (Read the full article)

Physical punishment is associated with a range of Axis I and II mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and physical health.

To our knowledge, this is the first nationally representative examination of harsh physical punishment and physical health. Harsh physical punishment in the absence of child maltreatment is associated with higher odds of cardiovascular disease (borderline significance), arthritis, and obesity. (Read the full article)

Retinal hemorrhage (RH) is an important sign of pediatric abusive head trauma. Raised intracranial pressure (ICP) is sometimes proposed as an alternate cause of RH in children being evaluated for possible child abuse.

Nontraumatic, markedly elevated ICP rarely causes RH in children. When it does, RH are superficial intraretinal and located adjacent to a swollen optic nerve head. This pattern does not match the widespread pattern seen in abusive head trauma. (Read the full article)

Assessment of general movements (GM) in early infancy is predictive of adverse neurologic outcome, particularly cerebral palsy. There is limited evidence of the predictive value of GM for other domains of neurodevelopment such as language and cognitive impairment.

Abnormal GM in preterm infants in the first 3 months postterm are predictive of a range of neurodevelopmental outcomes in early childhood. GM at 3 months are more accurate at distinguishing later neurodevelopment impairment than those at 1 month. (Read the full article)

Diabetic ketoacidosis (DKA) is a short-term complication of type 1 diabetes and is a major cause of preventable hospitalization in children. Hospital resource utilization and readmission rates for DKA across the US are not known.

Readmission for DKA within a year of hospitalization is common, accounting for one-fifth of all DKA admissions. Resource use, hospital length of stay, and readmission rates vary widely across major US children’s hospitals, even after adjusting for hospital differences in patients. (Read the full article)

The evaluation of blunt head trauma in children who undergo cranial computed tomography will occasionally reveal incidental findings. These findings may require further evaluation or intervention. The prevalence of incidental findings has previously been described using small cohorts, limiting generalizability.

This study is the largest pediatric multicenter description of the prevalence of incidental findings on cranial computed tomography. Incidental findings are categorized by urgency to describe the spectrum of abnormalities, providing a context for clinicians faced with these unexpected results. (Read the full article)

Neonatal infections are frequent complications in very preterm infants, already at high risk of neurologic and cognitive disabilities. Few studies have linked neonatal infections and neurodevelopmental outcomes. Those that did evaluated children only to the age of 22 months.

This study assessed the respective effects of early- and late-onset sepsis and their association with 5-year neurodevelopmental outcomes. We identified a significant and cumulative risk of cerebral palsy when episodes of early- and late-onset sepsis were associated. (Read the full article)

In 2001, an estimated 10 438 children were treated in US emergency departments for nonfatal choking on food. The foods most frequently associated with pediatric fatal choking are hot dogs, seeds, nuts, candy, and certain types of fruits and vegetables.

From 2001 through 2009, an estimated annual average of 12 435 children ages 0 to 14 years were treated in US emergency departments for nonfatal choking on food; 0- to 4-year-olds accounted for 61.7% of episodes. Foods most frequently involved were candy, meat, bone, and fruits/vegetables. (Read the full article)

The natural history of asthma during adolescence is dynamic because both remission and relapse are common. Remission has consistently been associated with mild asthma and the absence of sensitization.

One in 5 children with asthma remitted from age 7 to 19. Remission was defined as no wheezing and no medication for ≥3 years and was inversely related to female gender, sensitization to furred animals, and asthma severity at baseline. (Read the full article)

Although studies have examined family socioeconomic status as income and educational and employment status, emerging research suggests indicators of material hardship, such as diaper need, are increasingly important to child health. Diaper need has not been examined in the scientific literature.

This study quantifies diaper need, proposes a method to measure diaper need, and explores psychosocial and demographic variables associated with diaper need in a large sample of low-income families. (Read the full article)

Sugar-sweetened beverage (SSB) consumption in school-age children and adolescents is linked to heavier weight, and decreased SSB consumption results in less weight gain. Reports regarding these associations among children aged 2 to 5 years have been mixed.

Preschool-aged and kindergarten children drinking SSB compared with infrequent/nondrinkers had higher BMI z scores. SSB consumption is also associated with higher weight status among children aged 2 to 5 years. (Read the full article)

Critical congenital heart disease (CCHD) was recently added to the US Recommended Uniform Screening Panel for newborns.

Routine screening could cost an estimated additional $6.28 per newborn and $40 385 per life-year gained. The incremental cost of screening might be approximately $0.50 per newborn with reusable sensors. Future analysis of newborn screening programs may help refine these projections. (Read the full article)

The diagnosis of urinary tract infection (UTI) is confirmed by urine testing with urinalysis and culture. No study has characterized the use of urine testing in the setting of empirical antibiotic prescription for outpatient UTI in children.

Urine tests are not performed in a substantial percentage of antibiotic-treated pediatric UTIs. Additional research is necessary to determine whether empirical antibiotic prescription for UTI in children without urine testing is safe and effective. (Read the full article)

Bronchopulmonary dysplasia is associated with increased long-term neurodevelopmental and respiratory morbidity. Inhaled nitric oxide given to reduce morbidity in very preterm infants does not reduce the prevalence of bronchopulmonary dysplasia and has uncertain effects on long-term outcome.

Inhaled nitric oxide (5 ppm) given early in the course of respiratory illness in infants born before 29 weeks of gestation is not associated with changes in developmental or respiratory outcomes at 2 years of age corrected for prematurity. (Read the full article)

Newborns with critical congenital heart disease (CCHD) are at risk for cardiovascular collapse or death if discharged from the birth hospital without a diagnosis. Newborn screening aims to identify CCHD missed in prenatal and postnatal examinations.

Birth hospital nursery level and CCHD type were found to be associated with late CCHD detection. Routine newborn screening could conceivably reduce differences in the frequency of late diagnosis between birth hospital facilities. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

Bisphenol A (BPA) is a known endocrine disruptor found in many products with which children come into contact. Although BPA in adults is associated with obesity, diabetes, and cardiovascular disease, little is known about its effects in children.

This study found that higher BPA levels are associated with obesity and abnormal waist circumference–to–height ratio in children. (Read the full article)

Pulse oximetry screening at 24 hours of age improves detection of critical congenital heart disease in asymptomatic newborns.

This study describes an initial experience with pulse oximetry screening for critical congenital heart disease and provides a strategy for preparing for state implementation of recent federal newborn screening recommendations. (Read the full article)

The intestinal microbiome may play a role in immune system maturation, and it has been postulated that early-life probiotic administration may reduce the risk of allergies and asthma in childhood. To date, however, results from clinical trials have been inconsistent.

In this meta-analysis, administration of probiotics in early life may reduce total immunoglobulin E level and protect against atopic sensitization but do not seem to protect against asthma/wheezing. Future trials should carefully select probiotic strains and include longer follow-up. (Read the full article)

Phthalate exposure has been associated with insulin resistance in animal studies and cross-sectional studies of adults, but has not been studied in adolescents.

We detect associations of urinary phthalate metabolites in a cross-sectional study of US adolescents. The association is highly robust to multiple sensitivity analyses, and specific to phthalates commonly found in food. Further longitudinal study of dietary phthalate exposures is needed.

Effective implementation of Pediatric Emergency Care Applied Research Network head trauma rules depends on their early application. As the registered nurse (RN) is often the first to evaluate children with blunt head trauma, initial RN assessments will be an important component of this strategy.

We demonstrated fair to moderate agreement between RN and physician providers in the application of the Pediatric Emergency Care Applied Research Network head trauma rules. Effective implementation strategies may require physician verification of RN predictor assessments before computed tomography decision-making. (Read the full article)

Readmissions have been identified as a priority area for pediatric inpatient quality measurement nationally. However, it is unknown whether readmission rates vary meaningfully across hospitals and how many hospitals would be identified as high- or low-performers.

Only a few hospitals that care for children are high- or low-performers when their condition-specific revisit rates are compared with average rates across hospitals. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement. (Read the full article)
