Children investigated for alleged maltreatment have considerable physical, mental health (MH), developmental, and educational needs and often do not receive services to address these needs. The prevalence/correlates of MH services use in the current challenging financial environment is unknown.

This study demonstrates the importance of medical providers and schools for receipt of MH services for these children, but shows disparities in MH service use between white and nonwhite children. Unlike earlier findings, MH service use declined over the follow-up. (Read the full article)

Anecdotal accounts that suggest elopement behavior occurs in children with autism spectrum disorders (ASDs), that injuries and fatalities can result, and that associated family burden and stress are substantial. However, there has been little research characterizing the phenomenon or its frequency.

Nearly half of children with an ASD elope, and more than half of these "go missing." Elopement is associated with autism severity, and is often goal-directed. Addressing elopement behavior is an important aspect of intervention for many individuals with ASDs. (Read the full article)

Increased computed tomography (CT) use among adults and children presenting to emergency departments has spawned concern about associated radiation exposure. The risks and benefits of CT use for certain conditions, such as abdominal pain, among general pediatric populations remains unclear.

This study analyzes emergency department radiology trends between 1998 and 2008 among children with abdominal pain, highlighting a dramatic increase in CT use. Factors associated with CT ordering include older age, non-black race, and hospital admission. (Read the full article)

Retinal hemorrhages occur in accidental and inflicted traumatic brain injury (ITBI) and some medical encephalopathies. Large numbers and peripherally located retinal hemorrhages are frequently cited as distinguishing features of ITBI in infants, but the predictive value has not been established.

This prospective retinal imaging study found that a diagnosis of ITBI in infants and children can be distinguished from other traumatic and nontraumatic causes by the presence of >25 dot-blot (intraretinal layer) hemorrhages (positive predictive value = 93%). (Read the full article)

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a widely used universal prevention strategy currently implemented in >16 000 schools across the United States. Previous research has shown positive effects on school climate and school-level discipline problems.

This study reports multilevel results on data from a 4-year randomized controlled effectiveness trial of SWPBIS in 37 elementary schools. Results indicate significant impacts on children’s aggressive behavior problems, concentration problems, office discipline referrals, emotion regulation, and prosocial behavior.

Healthy sleep is essential for supporting alertness and other key functional domains required for academic success. Research involving the impact of modest changes in sleep duration on children’s day-to-day behavior in school is limited.

This study shows that modest changes in sleep duration have significant impact on the behavior of typically developing children in school. Modest sleep extension resulted in detectable improvement in behavior, whereas modest sleep restriction had the opposite effect. (Read the full article)

Brain maturation processes of very premature children are adversely affected by serious neonatal infections. Differences in brain development persist into childhood and adolescence, and underpin widespread neurocognitive and behavioral deficits in very preterm children.

We present evidence for long-term beneficial effects of early nutritional intervention with glutamine in very preterm infants on brain development at 8 years of age, mediated by a decrease in the number of serious neonatal infections. (Read the full article)

Clinical guidelines for the evaluation of suspected physical abuse in young children emphasize performing radiologic imaging to screen for occult fractures. Little is known about the degree of adherence to guidelines for screening for occult fractures among pediatric hospitals.

Adherence to guidelines related to screening for occult fractures in young children diagnosed with physical abuse varies significantly among pediatric hospitals. Use of screening in infants who have injuries associated with a high likelihood of abuse also varies among pediatric hospitals. (Read the full article)

Oral health researchers and policy makers primarily use 4 national surveys to examine use of dental services among US children. Estimates from the surveys may vary, posing a challenge to population-based monitoring.

The authors of this study compared estimates of dental service use and delayed dental care obtained from 4 commonly used health surveys to appraise their utility for guiding pediatric oral health research and policy. (Read the full article)

There are limited data on current testing and treatment patterns for children hospitalized with pneumonia, and on whether institutional guidelines affect care.

The use of institutional clinical practice guidelines was not associated with changes in diagnostic testing, hospital length of stay, or costs for children hospitalized with pneumonia, but was associated with increased use of narrow-spectrum antibiotics. (Read the full article)

Stress in parents has been shown to be related to child obesity.

The presence of multiple parent stressors was related to child obesity, and parent perception of stress was related to child fast-food consumption. Stress in parents may be an important risk factor for child obesity and related behaviors. (Read the full article)

Autism spectrum disorders are characterized by heterogeneous severity. Previous latent variable analyses of longitudinal data have focused on trajectories of related features such as IQ, and not on changes over time in standardized, observational measures of core autism symptoms.

Autism Diagnostic Observation Schedule–calibrated severity scores allow comparisons of observational data from toddlerhood to adolescence. This first report of latent autism severity trajectory classes indicates that most children show stability in core symptom severity over many years; small groups improved or worsened.

Fever without an apparent source is common in children. Currently in the United States, serious bacterial infection is uncommonly the cause. Most cases are assumed to be viral, but the specific viral causes have not been delineated. Antibiotics are frequently prescribed.

By using polymerase chain reaction, we detected pathogenic viruses frequently in children with fever without an apparent source. Adenovirus, human herpesvirus-6, enterovirus, and parechovirus were predominant. Testing of blood had high yield. Better recognition of viral etiologies may help reduce unnecessary antibiotic use.

Medical advances have prolonged life for children and adolescents with Duchenne muscular dystrophy (DMD), the most common inherited pediatric neuromuscular disorder. Children with this progressive disease surviving to adulthood still face significant threats to their quality of life.

Self-reported psychosocial quality of life was impaired in a significant number (57%) of boys with DMD, unrelated to their need for mobility aids. Concordance between the perceptions of parents and their sons related to psychosocial functioning was fair to poor. (Read the full article)

The past several decades have seen a dramatic increase in the costs of health care and the prevalence of childhood activity limitations. More families with children are experiencing financial burden related to the cost of health care and insurance.

We find significant inequities in the occurrence of delayed or forgone needed health care for families with children as a result of high health care–related financial burden and having a child with an activity limitation. (Read the full article)

Previous studies have demonstrated that booster seat legislation decreased fatalities in children. However, these studies have not accounted for confounding factors such as other legislation and temporal trends in safety.

This study demonstrates that state booster seat laws are associated with decreased rates of fatalities and injuries in children 4 to 7 years of age in the United States, with the strongest effects in the older children. (Read the full article)

Interventions to reduce screen time in preschool-aged children are promising.

A screen time intervention in 3-year-old children implemented in the primary care setting did not reduce screen time or BMI. (Read the full article)

Hypothalamic-pituitary-adrenal axis suppression caused by inhaled corticosteroids is considered rare. Adrenal crisis has been described in children treated with high doses of inhaled fluticasone propionate. It was recommended that doses licensed for children should not be exceeded.

Biochemically confirmed hypothalamic-pituitary-adrenal axis dysfunction may occur in two-thirds of children treated with corticosteroids. Suppression may occur at low doses and especially with concomitant nasal steroids. Children with poor adherence or obesity may be less prone to adrenal crisis. (Read the full article)

Tobacco smoke exposure is associated with increased morbidity in children, and exposure in cars can be particularly intense. The American Academy of Pediatrics policy statement recommends that pediatricians assist families in adopting smoke-free car policies.

In this study, few smoking parents had a strictly enforced smoke-free car policy. Low rates of pediatric health care providers addressing smoking in the car highlights the need for improved pediatric interventions to protect children from tobacco smoke toxins. (Read the full article)

Previous studies have found variable child care provider compliance with American Academy of Pediatrics child care illness exclusion guidelines and high rates of unnecessary exclusion of mildly ill children from child care.

Our study is the first to compare child care directors’ return-to-child care practices before the release of the new American Academy of Pediatrics return-to-child care guidelines and to describe the guidelines’ impact if actively adopted by child care providers. (Read the full article)

Nationally representative surveys provide insight into overall childhood obesity trends and disparities but do not identify patterns specific to individual states. School-based surveillance is recommended, but it is unclear whether surveillance is helping to identify children at greatest risk.

This study includes 3 consecutive years of surveillance findings to describe within-state spatial and socioeconomic disparities in obesity among elementary-aged children. Implications for states using and considering school-based surveillance to plan preventive interventions are considered. (Read the full article)

Some groups of children are especially prone to develop overweight and obesity. Overweight in children affects their physical and psychological health and shortens life expectancy. Overweight in children with Down syndrome (DS) is attributed to their commonly found comorbidities.

This study provides prevalence rates of overweight and obesity in a nationwide sample of otherwise healthy children with DS. Overweight is observed from young ages in healthy children with DS and those with severe congenital heart defects. (Read the full article)

Disparities in vaccination coverage between American Indian/Alaska Native and white children previously existed between 2001 and 2004 but were not present in 2005.

This study updates a previous study by analyzing data through 2010 and found that these gains have been maintained. (Read the full article)

Doxorubicin therapy, effective against many malignancies, is limited by cardiotoxicity. Continuous-infusion doxorubicin, compared with bolus-infusion, reduces early cardiotoxicity in adults. Its effectiveness in reducing late cardiotoxicity in children remains uncertain.

This multicenter randomized trial assessed whether continuous-infusion of doxorubicin in pediatric patients provides long-term cardioprotection or improvement in event-free survival over bolus-infusion in acute lymphoblastic leukemia. Continuous-infusion of doxorubicin provided no cardioprotection or improvement in event-free survival. (Read the full article)

Children with medical complexity are high users of acute health care, but little is known about their service use across the continuum of care services and in the context of overall health care expenditures.

Although accounting for <1% of the child population, children with medical complexity use almost one-third of all pediatric health care expenditures and make multiple transitions across providers and health care settings. (Read the full article)

Pediatric tuberculosis is significant for public health professionals because it is an indicator of the recent transmission of tuberculosis in the community. Data on incidence and clinical features of pediatric tuberculosis from China are scarce.

We conducted this study to describe the patient characteristics, clinical–epidemiological profile, and treatment outcomes for pediatric tuberculosis in a referral hospital setting in China. (Read the full article)

Medical imaging that uses ionizing radiation provides notable benefits in the clinical setting. Controversy regarding increased cancer risk, particularly in children, dictates that ordering practices and use of such medical imaging be evaluated to reduce unnecessary exposure to imaging-related radiation.

We evaluated the prevalence and characteristics of diagnostic imaging procedures in children. The proportion of higher radiation procedures is increasing, especially among children evaluated in the inpatient and emergency department settings and those with gastrointestinal and neurologic symptoms, and congenital anomalies.

Asthma is a common focus of pediatric quality improvement efforts. Various processes of care have been postulated as markers of high-quality pediatric asthma care, but it is not clear which processes correlate with a lower risk of asthma exacerbations.

This study analyzed the correlation of processes of care identifiable through administrative data with asthma exacerbations. The use of 0 vs ≥1 controller medications and the asthma medication ratio had the strongest correlation with asthma exacerbations. (Read the full article)

Most observational studies from Western populations suggest that blood pressure is positively associated with low birth weight and faster infant growth; however, it is unclear whether these associations are biologically based or contextually specific.

In a developed non-Western setting with relatively little socioeconomic patterning of size or growth, birth weight and infant growth had relatively limited impacts on early adolescent blood pressure, which was more strongly related to recent growth and current size. (Read the full article)

Gaining intravenous access in children can be difficult. Recently, several near-infrared devices have been introduced attempting to support intravenous cannulation by visualizing veins underneath skin. Only one of those devices has been evaluated systemically thus far and results are inconclusive.

Although it was possible to visualize veins with near-infrared in most patients, the VascuLuminator did not improve the success of cannulation. An explanation is that the main problem is probably not localization of the vein but insertion of the cannula. (Read the full article)

Cerebral edema (CE) occurs frequently during treatment of diabetic ketoacidosis (DKA) in children. Severe, life-threatening CE occurs rarely, but subclinical CE is common. Whether the rate of infusion of intravenous fluids influences the occurrence or severity of CE is unknown.

This study demonstrates that the rate of fluid infusion in children with DKA does not substantially affect MRI measures of CE. Studies assessing measures other than edema formation are necessary to determine whether fluid infusion rates influence DKA-related brain injury. (Read the full article)

Maternal obesity is an increasingly important public health concern and may adversely affect central nervous system development in offspring. However, few studies have explored the relationship between maternal prepregnancy BMI and neurodevelopmental outcomes in children, with conflicting results.

Using data from a large and contemporary UK birth cohort, we found that maternal prepregnancy BMI is negatively associated with children’s cognitive performance. The relationship appears to become stronger as children get older, although the overall effect size is modest. (Read the full article)

There is widespread belief that many hospital readmissions in adults are avoidable by improvements in care and discharge planning processes, resulting in significant cost savings; however, current studies have not examined the preventability of such readmissions in children’s hospitals.

The overall rate of pediatric 15-day readmissions considered to be preventable was low, less than 2% of total hospital admissions. Pediatric readmissions are unlikely to serve as a highly productive focus for cost savings or quality measurement. (Read the full article)

The medical home likely plays a positive role in outpatient health outcomes. Asthma is a common and frequent reason for pediatric hospitalization. It is unknown whether having a quality medical home can prevent readmission in children hospitalized for asthma exacerbations.

Poor access to a medical home was associated with increased readmission for asthma, whereas other measured aspects of medical home were not. Children with private insurance and good access to care had the lowest rates of readmission within a year. (Read the full article)

Children with congenital heart disease (CHD) are at increased risk for poor growth. Several factors may play a role in poor growth, including feeding difficulties, increased caloric requirements, and the effects of cardiac lesions on growth regulation.

In children with CHD, impaired growth as measured by weight, length, and head circumference occurs simultaneously rather than sequentially, supporting the theory that altered growth regulation likely plays an important role in the poor growth of children with CHD. (Read the full article)

Outcomes analyses after trauma reveal long-term disability but are limited to specific injuries, older data, or all ages combined. There are no contemporary assessments of physical disability among children after inpatient rehabilitation for a wide range of traumatic injuries.

This is the first contemporary study to describe the physical disability of a large pediatric cohort after inpatient rehabilitation for various injuries. After a mean 21-day inpatient rehabilitation stay, significant reductions in functional disability were achieved across injury mechanisms. (Read the full article)

There is evidence that Kingella kingae, the major bacterial cause of osteoarticular infection in children <4 years of age, first colonizes the oropharynx before penetrating the bloodstream and invading distant organs. Diagnosis remains challenging because clinical findings at admission may be normal.

Our study demonstrated for the first time that a simple technique of detecting of K kingae DNA in the oropharynx can provide strong evidence that this microorganism is responsible for the OAI, or even stronger evidence that it is not. (Read the full article)

Cow’s milk consumption has opposite effects on vitamin D and iron levels in children; however, the amount of cow’s milk intake required for sufficient stores of vitamin D and iron is poorly understood, and existing guidelines on consumption are unclear.

Two cups of cow’s milk per day is sufficient to maintain healthy vitamin D and iron stores for most children. Wintertime vitamin D supplementation appears particularly important among children with darker skin pigmentation. (Read the full article)

Although survival of children born with Down syndrome has improved, unexplained racial and ethnic disparities in survival persist in the United States.

This study used population-based data from 10 birth defects monitoring programs in the United States to examine survival trends among children born with Down syndrome and to evaluate the changing influence of survival predictors over the life course. (Read the full article)

Infants and toddlers with deformational plagiocephaly (DP) score lower on developmental measures than children without DP and lower than expected relative to test norms.

This study is the first to examine developmental outcomes in preschool-aged children with DP relative to demographically similar children without DP using a standardized, clinician administered assessment. (Read the full article)

Adequate vitamin D is essential for skeletal health in developing children. Although excess body weight is associated with risk of vitamin D deficiency, the national prevalence of vitamin D deficiency in overweight and obese children is unknown.

Vitamin D deficiency is highly prevalent in overweight and obese children, and severely obese and minority children are disproportionately affected. There are many modifiable factors associated with vitamin D deficiency in overweight and obese children. (Read the full article)

Lifestyle and vulnerability associated with food allergy might predispose affected children to being bullied. Our previous parent survey identified high rates of bullying in this population, but child reports and emotional impact were not assessed.

Bullying was common, often involving threats with food. Bullied food-allergic children, compared with nonbullied, report higher anxiety and lower quality of life. Parental awareness of bullying (~50% of cases) was associated with better social and emotional functioning in the child. (Read the full article)

Childhood headache is a common medical condition and can negatively impact a child’s social and academic life in several ways. Early and accurate diagnoses of headache syndromes, including migraine, are essential to appropriate treatment and outcome for affected youth.

The Diagnostic Interview of Headache Syndromes–Child Version is a new tool for the assessment of pediatric migraine that can enhance the standardization of collection of diagnostic criteria in both clinical and community settings, leading to better recognition and treatment of this condition.

Influenza is an important cause of medically attended illness in young children before expanding influenza vaccine recommendations for children.

This study characterizes the health care burden of influenza in young children over 5 years (2004–2009) when influenza vaccine recommendations were expanded to all children aged ≥6 months. (Read the full article)

Paternal mental disorders during the postnatal period are associated with an increased risk for behavioral and emotional problems in their children; however, less is known about the effect of fathers’ mental health during pregnancy on children’s development.

The study demonstrated a positive association between fathers’ prenatal mental health and their children’s subsequent socioemotional and behavioral development. Psychological distress in fathers was associated with a risk for emotional difficulties in their children at 36 months of age. (Read the full article)

Validated questionnaires can improve the identification of psychosocial problems among children. The Strengths and Difficulties Questionnaire (SDQ) 3-4 is a promising option. However, no studies are available that examine the psychometric properties of the SDQ parent form 3-4.

The results of this study show that the SDQ 3-4 is a valid tool for the identification of psychosocial problems in preschool-aged children. (Read the full article)

Previous studies suggest that hospitals under the greatest financial strain may be more prone to adverse events because they have limited resources to invest in quality and safety.

The patient population served, rather than hospital category, best predicts measured quality, underscoring the need for robust risk adjustment when incentivizing quality or comparing hospitals. Thus, problems of quality may not be systemic across hospital categories. (Read the full article)

A reduced nephron number is associated with glomerular hyperfiltration, resulting in renal injury such as hypertension, proteinuria, and chronic kidney disease. Patients with a solitary functioning kidney have an increased risk of dialysis in early adulthood.

This study demonstrates that a subset of children with a solitary functioning kidney progress toward renal injury during childhood. Risk factors for renal injury are ipsilateral anomalies of the kidney and urinary tract and small renal length. (Read the full article)

Effective interventions are still elusive for the large numbers of children affected by overweight/obesity. The value of targeting physical activity (PA) remains unclear because its predictive relationship with improved BMI is still surprisingly poorly quantified.

In overweight and mildly obese children presenting to primary care, 3-year changes in PA (especially the moderate-vigorous component) predicted BMI outcomes. However, the effect was small, possibly explaining the disappointing BMI outcomes of brief primary care interventions targeting PA. (Read the full article)
