Caregiver behavioral symptom ratings are frequently used to assist in diagnosing childhood behavioral disorders. Although behavioral disorders are highly comorbid with learning disabilities (LDs), little work has examined the utility of caregiver ratings of learning concerns for screening of comorbid LD.

The validity of a time- and cost-efficient caregiver rating of academic concerns (Colorado Learning Difficulties Questionnaire) was examined. The screening measure accurately predicted children without LD, suggesting that the absence of parent-reported difficulties may be adequate to rule out overt LD. (Read the full article)

Prenatal exposures to diverse pollutants and psychosocial stressors have been shown independently to adversely affect child development. Less is known about the potential interactions between these factors, although they commonly co-occur, especially in disadvantaged populations.

The combination of high prenatal exposure to environmental polycyclic aromatic hydrocarbons and maternal demoralization adversely affects child behavior, and maternal demoralization has a greater effect among children with high prenatal polycyclic aromatic hydrocarbon exposure for a majority of behavioral symptoms.

Palivizumab prophylaxis prevents respiratory syncytial virus lower respiratory tract infection. An association between respiratory syncytial virus infection and subsequent recurrent wheezing has been suggested by many studies. Only a few studies conducted from Europe and North America have addressed this causal association.

In a prospective, multicenter, case-control study of 440 children with high follow-up rate of 98.4%, palivizumab prophylaxis administered to preterm Japanese infants (33–35 weeks’ gestational age) in their first respiratory season reduced the incidence of subsequent recurrent wheezing up to 3 years.

End-stage kidney disease (ESKD) causes significant morbidity and mortality after solid organ transplantation. Adults commonly develop advanced kidney disease, particularly after liver and intestinal transplantation. Previous pediatric studies have not compared the relative incidence of ESKD by organ type.

This national cohort study shows the highest risk of ESKD among pediatric lung and intestinal transplant recipients, reflecting unique organ-specific causes of kidney injury. Our findings have implications for screening for and treating early kidney disease in transplant recipients. (Read the full article)

Links between clinically diagnosed sleep problems and adverse behavioral outcomes are well documented. However, in nonclinical populations, causal links between disrupted sleep and the development of behavioral difficulties are far from clear.

Seven-year-old children with nonregular bedtimes had more behavioral difficulties than children who had regular bedtimes. There were clear dose–response relationships, and the effects of not having regular bedtimes appeared to be reversible. (Read the full article)

Pediatric functional abdominal pain is common and costly. Cognitive behavior therapy (CBT) is a promising treatment for these complaints, but solid evidence for its effectiveness is lacking.

This randomized controlled trial shows that CBT reduces abdominal pain in 60% of children 1 year after treatment. Six sessions of CBT delivered by trained master’s students in psychology were equally effective as 6 visits to an experienced pediatrician. (Read the full article)

Higher-hazard, no-benefit research involving children may be approved by local institutional review boards only when the protocol enrolls children with the medical condition under study. The ethics of this distinction have been debated, but parental opinions have not been explored.

We found that parental opinions support federal regulations. We discuss parental motivations for and against research participation and the extent to which enrolling a child in higher-hazard, no-benefit research reflects appropriate surrogate decision-making. (Read the full article)

In January 2006, a public health advisory and boxed warning for long-term safety and the risk of malignancies and a medication guide were issued for topical calcineurin inhibitors, tacrolimus and pimecrolimus.

Evaluation of off-label use of topical calcineurin inhibitors in children before and after regulatory action by the Food and Drug Administration is important to understand the impact of regulatory action. (Read the full article)

Gunshot injuries are an important cause of preventable injury and mortality in children, with emergency services often providing the initial care for patients. However, there is little recent population-based research to guide public health, injury prevention, and health policy efforts.

Gunshot injuries are uncommon in children, but cause greater injury severity, need for major surgery, mortality, and costs compared with other injury mechanisms. There is also large variation in the population-adjusted incidence of pediatric gunshot injuries between regions. (Read the full article)

Use of complementary and alternative medicine (CAM) is increasingly common among American youth; however, information on use of CAM among youth with recurrent headache (HA) is limited.

Youth across a range of chronic conditions experience HA. These youth are more likely to use CAM. Use and expenditures for conventional medical care, and increased difficulties in activity and functioning are greater for youth with HA who use CAM. (Read the full article)

Physical activity (PA) levels in preschool children vary considerably between preschools, and are positively associated with the overall quality of the preschool. However, knowledge regarding specific characteristics of the preschool environment hypothesized to promote PA is inconsistent and lacking.

This study tested multiple potential correlates of preschool children’s objectively measured moderate and vigorous PA level during preschool attendance, identifying size of indoor area per child and location of preschool building on the playground as new potentially modifiable correlates.

A large and growing literature has demonstrated significant associations between the use of spanking and later child aggression, but we know less about paternal spanking, effects of spanking on cognitive development, and longer-term effects.

Accounting for a broad array of risk factors, spanking predicts both aggression and receptive vocabulary across the first decade of life. Importantly, we include paternal spanking, cognitive outcomes, and a longitudinal span longer than that of much of the literature. (Read the full article)

Obesity and overweight can seriously affect health outcomes. Many obesity prevention interventions have been proposed, but few have been effective. Motivational interviewing in primary care seems promising, but results in BMI control are controversial and require further investigation.

This is the first study to demonstrate the effectiveness of pediatrician-led motivational interviewing for BMI control in overweight children aged 4 to 7 years. Nevertheless, no effect was observed in boys or when the mother’s education level was low. (Read the full article)

Transition from pediatric to adult care is often reported to be unsuccessful. Little evidential research has examined the actual proportion of youth in pediatric versus adult care or impact on health status outcomes after transferring from pediatric to adult care.

Our article extends the literature by providing health transition outcome data, something that has been recognized as a critical gap to developing evidence-based programming and health care transition policy. (Read the full article)

Pertussis rates are on the rise in the United States. Infants often require hospitalization for pertussis. Vaccination can change hospitalization patterns for vaccine-preventable diseases. It is unknown if vaccinating adolescents for pertussis (recommended in 2006) might change infant hospitalization utilization.

Universal vaccination policy among adolescents against pertussis appears to have been effective in 3 of the 4 years we examined postvaccination. Further vaccination efforts among adolescents and adults are needed to prevent infantile hospitalization on a more consistent basis. (Read the full article)

Cooling infants with hypoxic-ischemic encephalopathy shortly after birth improves survival and neurodevelopmental outcome. The optimal way to cool infants during transfer to regional NICUs is unclear.

Data from a regional neonatal transfer team, using first passive and subsequently active cooling for these infants, suggest that active cooling results in improved thermal control and a reduction in stabilization time. (Read the full article)

Several studies have shown that behavioral problems can be associated with defecation and voiding disorders, although few studies have looked directly at a link between a diagnosis of attention-deficit/hyperactivity disorder (ADHD) and constipation or fecal incontinence.

We identified an increased risk for both constipation and fecal incontinence in children with ADHD. In patients with concomitant ADHD and defecation disorders, more aggressive medical and behavioral treatment of the constipation or fecal incontinence may be warranted. (Read the full article)

Although providing improved survival for infants with very severe cardiorespiratory problems, the use of neonatal extracorporeal membrane oxygenation has high rates of disability in survivors. Mild hypothermia has been shown to limit brain injury in a range of patient groups, including newborns.

Infants who received extracorporeal membrane oxygenation and mild hypothermia did not show an improved neurodevelopmental outcome, and nonsignificant trends in the data suggested a small adverse effect. Use of hypothermia in other potential patient groups should be thoroughly tested. (Read the full article)

Sharing human milk between those with an abundant supply and those seeking milk for their child may be growing in popularity, facilitated by Web sites recently established to link providers and recipients.

This study documents the potential for human milk shared via the Internet to cause infectious disease by estimating the extent of microbial contamination among samples purchased via a leading Internet Web site. (Read the full article)

Psychotropic use is common and increasing in children with mental disorders but little is known about the long-term patterns of psychotropic use and polypharmacy among commercially insured children with autism spectrum disorders.

Among 33 565 children with autism spectrum disorders, 64% used psychotropic medications and 35% had evidence of polypharmacy. Older children and those who had seizures, attention-deficit disorders, anxiety, bipolar disorder, or depression had increased risk of psychotropic use and polypharmacy. (Read the full article)

School outbreak investigation in Quebec, Canada suggested that adolescents previously vaccinated with 2 doses of measles vaccine beginning at 12 months of age were at greater measles risk than those whose first dose was given at ≥15 months of age.

Greater measles risk among earlier first-of-2-dose vaccine recipients was replicated as a generalized provincial finding during the 2011 epidemic in Quebec, Canada. The mechanism remains unknown, but the findings warrant additional evaluation in the context of measles elimination efforts. (Read the full article)

Unintentional overdose and emergency department visits secondary to nonmedical use of prescription drugs are on the rise with peak age of onset in midadolescence for these risk behaviors. Also, risk behaviors, such as substance use and violence, tend to cluster.

Approximately 1 in 10 adolescents or young adults using the emergency department endorse nonmedical prescription opioid or sedative use in the past year. Rates of current opioid or sedative prescriptions are low among this group. (Read the full article)

The etiology of childhood cancers is largely unknown. However, excessive fetal growth has been associated with some childhood cancers. One of the most consistent findings is that high birth weight is associated with an increased risk of childhood leukemia.

Examining large, population-based birth and cancer registry data from 4 Nordic countries, high birth weight was the most strongly associated with risk of many childhood cancers among several measures of fetal growth that have not previously been extensively assessed. (Read the full article)

As more children with sickle cell disease survive into adulthood, they are increasingly hospitalized in both children’s and general hospitals and managed by different provider specialists. But it is unknown if hospital type and provider specialty affect patient outcomes.

Using a large national administrative dataset, this study revealed that general hospitals were associated with higher rates of intubation and longer lengths of stay compared with children’s hospitals for adolescents and young adults with SCD admitted with acute chest syndrome. (Read the full article)

Previous studies have found links between prepregnancy BMI and/or pregnancy weight gain and autism spectrum disorders (ASD) risk. Several contributing factors to BMI and pregnancy weight gain (ie, prematurity, advanced maternal age, parental education, and parity) overlap with established ASD risk factors.

This study identifies an association between ASD risk and prenatal weight gain, but not prepregnancy BMI, and accounts for important confounding variables excluded in previous analyses. It provides the first within-mother comparison of these factors by including unaffected sibling controls. (Read the full article)

Influenza-associated deaths in children occur every year among children of all ages. Young children and those with high-risk medical conditions are at higher risk of influenza-related complications.

This study describes influenza-associated pediatric deaths over 8 influenza seasons in the United States and compares characteristics of deaths in children with high-risk medical conditions with those in children without high-risk medical conditions. (Read the full article)

Some studies suggest a contribution of environmental exposures such as pesticides to risk of hypospadias, whereas others do not. One of the challenges that has limited current knowledge is the lack of detailed exposure data.

This study examined a more detailed assessment of exposure to pesticides than previous studies. Exposure assignments, whether to groups of chemicals, specific chemicals, or a composite involving a number of chemicals, showed a general lack of association with hypospadias. (Read the full article)

Recent guidelines for the management of childhood pneumonia recommend narrow-spectrum antimicrobial agents (eg, ampicillin) for most children; however, few studies have directly compared the effectiveness of narrow-spectrum agents to the broader spectrum third-generation cephalosporins commonly used among children hospitalized with pneumonia.

By using data from 43 children’s hospitals in the United States, we demonstrate equivalent outcomes and costs for children hospitalized with pneumonia and treated empirically with either narrow- (ampicillin/penicillin) or broad-spectrum (ceftriaxone/cefotaxime) antimicrobial therapy.

It has previously been shown that exposure to intimate partner violence and/or parental depression or anxiety may increase a child’s risk for specific adverse health outcomes.

By using a large pediatric primary care sample, this study examined associations of child exposure to intimate partner violence and parental psychological distress with developmental milestone attainment by analyzing their combined and separate effects while adjusting for other family factors.

Epidemiologic studies have documented that children’s sleep duration is associated with obesity risk. Experimental studies with adults suggest that short sleep may lead to changes in appetite-regulating hormones and food intake, which could lead to weight gain over time.

This controlled experimental study demonstrates that compared to sleeping less, when children increase sleep, they report decreased caloric intake, have lower fasting leptin levels, and weigh less. Such changes, if maintained, could help prevent excess weight gain over time. (Read the full article)

Over the past 10 years, children’s hospitals increasingly have established pediatric palliative care programs, but little is known about the prevalence of these programs or their geographic distribution, range of services offered, staff composition, or funding.

Among the 162 hospitals that responded to this survey (71.7% response rate), 69% have a pediatric palliative care program, with substantial variation across programs in terms of how they are staffed and funded and what services they provide. (Read the full article)

An increasing number of parents have concerns about childhood vaccines. Parents consistently cite their child’s provider as influential in their vaccine decision-making. Little is known about how providers communicate with parents about vaccines and which communication strategies are important.

How providers initiate the vaccine recommendation at health supervision visits appears to be an important determinant of parent resistance. Also, when providers pursue their original vaccine recommendations in the face of parental resistance, many parents subsequently agree to vaccination. (Read the full article)

Levels of daily physical activity in children are decreasing worldwide. This implies risk factors for cardiovascular and metabolic diseases.

Strength training makes children not only stronger but significantly increases their daily spontaneous physical activity outside the training intervention. (Read the full article)

Children with chronic illnesses tend to be sicker during infections than previously healthy children but are triaged in the same way, even though the validity of triage systems has not yet been evaluated in these chronically sick children.

The performance of the Manchester Triage System was lower for children with a chronic illness than for previously healthy children. Children with cardiovascular illnesses, respiratory illnesses, gastrointestinal illnesses, or other congenital or genetic defects were especially at risk of being undertriaged.

NF1 is the commonest single-gene neurodevelopmental disorder with known neurobiology and developmental impact on attention and cognition. Its impact on social functioning is described but poorly understood, with no population-based study of autism spectrum disorder (ASD) prevalence in the disorder.

This epidemiological study shows high prevalence of 25% ASD in NF1 not explained by learning difficulties. ASD should be considered during clinical practice with NF1. Further research into NF1 as a single-gene model of ASD is warranted. (Read the full article)

Several studies have documented earlier onset of pubertal maturation in girls, with several potential factors attributed to the earlier onset.

This study demonstrates earlier maturation in white non-Hispanic girls, with greater BMI linked as a major factor. The entire distribution of pubertal timing has shifted to a younger age, suggesting redefinition of ages for both early and late maturation. (Read the full article)

The World Health Organization estimates that ~700 million children breathe tobacco smoke polluted air, particularly at home. Educational strategies either directly or indirectly targeting household decision-makers through other family members are effective in reducing children's exposure in private homes.

Intensive intervention was effective in decreasing children’s personal exposure to secondhand smoke (SHS), educating mothers about SHS, and promoting smoking restrictions at home. However, superiority over minimal intervention to decrease children’s personal exposure to SHS was not statistically significant. (Read the full article)

Preterm infants are born with low serum levels and low body stores of tocopherol. Serum levels ≥0.5 mg/dL are required for protection against lipid peroxidation. Previous studies have shown good intestinal absorption of vitamin E given intragastrically to preterm infants.

Serum α-tocopherol increases after a single 50-IU/kg dose of vitamin E as dl-α-tocopheryl acetate given intragastrically to very preterm infants soon after birth; however, 30% of infants still have serum α-tocopherol level <0.5 mg/dL 24 hours after dosing. (Read the full article)

Previous research has shown the following: the mere presence of weapons can increase aggression, dubbed the "weapons effect"; violence in films has increased over time; and violent films can increase aggression.

This study examines a potential source of the "weapons effect": the presence of guns in films. In just 20 years, gun violence in PG-13 films (age 13+) has increased from the level in films rated G/PG to the point where it exceeds the level in R films. (Read the full article)

To prevent asthma exacerbations, asthma guidelines recommend ongoing monitoring of patients’ asthma symptoms to promote timely adjustments of therapy to achieve and maintain optimal control. Existing tools, validated for ongoing monitoring, have significant limitations in children.

Our study established longitudinal validation of the Asthma Symptom Tracker, a novel tool designed for use by children or their parents to facilitate ongoing monitoring of patients’ asthma symptoms and proactive medical decision-making to prevent acute exacerbations. (Read the full article)

Peripherally inserted central catheters (PICCs) are essential to deliver life-saving treatment to neonates. Longer PICC dwell times may increase the risk of central line–associated bloodstream infections (CLABSIs) in neonates, but previous studies have yielded inconsistent results, likely due to different study designs, analytic methods, and small sample sizes.

The risk of CLABSIs increases during the 2 weeks after PICC insertion and remains elevated for the catheter duration. These data support daily review of PICC necessity, optimization of catheter maintenance practices, and consideration of novel strategies to prevent CLABSIs. (Read the full article)

Bullying involvement is associated with deleterious psychological, educational, and health effects. However, little is known about relations between bullying involvement and sexual risk-taking behaviors or whether similar patterns hold for heterosexual and gay, lesbian, bisexual, transgendered, or questioning adolescents.

Among adolescents, bullies and bully-victims engaged in more casual sex and sex under the influence than their peers. Controlling for demographic characteristics and other victimization exposures, bully and bully-victim status predicted sexual risk taking but primarily for heterosexual adolescents.

In 2007, manufacturers voluntarily withdrew over-the-counter (OTC) infant cough and cold medications (CCMs) from the US market. A year later, manufacturers announced OTC CCM labeling would be revised to warn against OTC CCM use by children aged <4 years.

Among children aged <2 and 2 to 3 years, emergency department visits for CCM adverse events declined nationally after the withdrawal and labeling revision announcement relative to all adverse drug event visits. Unsupervised ingestions caused most CCM adverse events after each intervention. (Read the full article)

Certain characteristics of the sleep environment increase the risk for sleep-related, sudden, and unexplained infant death. These characteristics have the potential to generate asphyxia. The relationship between the deaths occurring in these environments and neurochemical abnormalities in the brainstem that may impair protective responses to asphyxia is unknown.

We report neurochemical brainstem abnormalities underlying cases of sudden infant death that are associated with and without potential asphyxial situations in the sleep environment at death. The means to detect and treat these abnormalities in infants at risk are needed. (Read the full article)

Preterm infants can be successfully resuscitated with <100% oxygen (O₂); however, initiation with room air remains controversial. Current Neonatal Resuscitation Program (NRP) guidelines suggest using air or blended O₂ to titrate O₂ to meet target preductal saturation goals.

This is the first trial to compare a limited O₂ strategy to target NRP–recommended transitional goal saturations versus a high O₂ strategy in preterm infants. The limited O₂ strategy decreased integrated excess oxygen and oxidative stress and improved respiratory outcomes. (Read the full article)

Global health is of increasing interest and relevance to North American pediatric trainees. Opportunities for resident global health training and exposure are most often limited to electives or trainees in dedicated global health tracks.

A series of short, structured, participatory global child health modules improved knowledge and were well received and integrated within academic programs. Such modules enable global health learning for all residents, including those who never intend to practice overseas. (Read the full article)

Bacteremia occurs in 2.2% of febrile infants who have a blood culture drawn. Regional data suggest that Escherichia coli, group B Streptococcus, and Staphylococcus aureus are leading causes; however, the geographic boundaries of these data limit universal applicability.

This is the first national study examining epidemiology of bacteremia in febrile infants admitted to a general inpatient unit. The most common pathogens were Escherichia coli (42%), group B Streptococcus (23%), and Streptococcus pneumoniae (6%). No Listeria monocytogenes was identified. (Read the full article)

Psychosocial stress in childhood has been associated with a greater risk of future overweight, although the associations have not always been consistent, the types of psychosocial stressors have often been somewhat extreme, and moderators of the association have rarely been examined.

Experiencing many negative life events in childhood, particularly with chronicity or events that are family health related, increases risk of overweight by age 15 years. Maternal obesity and greater delay of gratification for food each intensify this risk. (Read the full article)

Young age at first sexual intercourse (FSI) is related to risk-taking behaviors and negative outcomes. Previous studies using a cohort or cross-sectional design have concluded that younger age at menarche (AAM) is related to younger age at FSI.

This large birth cohort study is the first to address the temporal relationship between AAM and FSI. We found that younger AAM does not confer higher risk of early FSI, whether in terms of calendar age or time since menarche. (Read the full article)

Stable health insurance coverage facilitates access to health care. Despite expanded coverage options for children, parents report barriers to accessing insurance programs for their children, including uncertainty about a child’s coverage status and eligibility.

Electronic health records can be used as an emerging data source for conducting health insurance surveillance to track trends in patients’ insurance coverage status, and to identify patients who may benefit from outreach and support to obtain and maintain coverage. (Read the full article)
