For newborn infants, extreme hyperbilirubinemia (≥24.5 mg/dL) is associated with risk for severe bilirubin encephalopathy. The causal factor of extreme hyperbilirubinemia is often not established. The genotype of Gilbert syndrome, the UGT1A1*28 allele, is considered a potential risk factor.

The UGT1A1*28 allele was not associated with risk for developing extreme hyperbilirubinemia. (Read the full article)

Severe complications, such as respiratory failure, have been described in influenza infection. Clinicians are commonly faced with influenza-like illnesses (ILI), which is the initial nonspecific presentation of many respiratory viruses; the risk of severe complications from ILI are unknown.

Severe complications occurred in children initially presenting with ILI, irrespective of the virus identified. Risk factors for severe complications did not differ by demographics or respiratory virus, although children with high-risk conditions are at greater risk of severe complications.

XY disorders of sex development have a diverse etiology and often present with atypical genitalia in the newborn period. Sex assignment in those cases in whom this is marked genital ambiguity is a rare, challenging situation that requires multidisciplinary input.

An international registry has shown temporal changes over the last 3 decades in the practice of sex assignment with a greater proportion of severely affected infants being raised as boys, raising the need for long-term monitoring of these children. (Read the full article)

In-person peer counseling to pregnant and new mothers has been shown to improve breastfeeding modestly in three US RCTs. But this level of support for WIC is unlikely to be scaled up nationally in the current fiscal environment.

We randomly assigned WIC clients to a telephone peer counseling program relative to standard WIC support for breastfeeding. Nonexclusive breastfeeding among Spanish-speakers increased at 1, 3, and 6 months, but the program had much less of an effect on English-speaking clients. (Read the full article)

Lower respiratory tract infections (LRTIs), including pneumonia, are in the top 10 causes of death among children in the United States. In high-income countries, 3% to 14% of LRTI hospitalizations have been reported to require admission to an ICU.

During 2007–2011, approximately 31 289 hospitalizations for severe LRTI occurred in children each year in the United States. Children <1 year of age had the highest rates of severe LRTI and accounted for 30% of severe LRTI hospitalizations. (Read the full article)

Arthropod-borne viruses are important causes of neurologic infections among children in the United States. The epidemiology of these diseases is complex and relates to multiple factors, including vector biology, animal reservoirs, weather, and human behavior.

National surveillance data from 2003 to 2012 will improve understanding of the geographic, temporal, and clinical trends in pediatric neuroinvasive arboviral disease, and will inform decision-making for clinicians, public health authorities, and the general public. (Read the full article)

Herpes encephalitis outside the neonatal period is typically severe and recognizable to clinicians. Excessive testing for herpes encephalitis is associated with increased medical costs and hospital length of stay, and risks patient harm.

Herpes testing and empirical acyclovir treatment in older and less unwell patients has been increasing in US pediatric hospitals over the past decade, which may reflect a more fundamental problem in current approaches to clinical decision-making. (Read the full article)

Previous studies examining developmental outcomes associated with late preterm and early term birth have shown mixed results. Many of these studies did not fully take into account the role of the social environment in child development.

Social factors, not late preterm or early term birth, were the strongest predictors of poor developmental outcomes at 2 to 3 and 4 to 5 years. The influence of mild prematurity may lose strength beyond the neonatal period. (Read the full article)

Prescribing patterns in the US pediatric population are changing but not uniformly. A detailed examination of prescription variation is needed to better understand pharmacotherapy of children and to inform future exploration of the causes and consequences of diverse practices.

We examine pediatric pharmacotherapy and quantify payer type differences and small geographic area variation. Substantial payer-type differences and regional variations were found, likely reflecting local practice cultures. Variation was greatest for medications used in situations of diagnostic and therapeutic uncertainty. (Read the full article)

Cigarette smoking during adolescence causes significant health problems. Health care providers play an important role in promoting tobacco use abstinence among adolescents, but recent data on the prevalence of provider screening and advice to adolescents are lacking.

This study uses nationally representative surveillance data to provide current estimates of self-reported receipt of health professional screening and advice about tobacco use among US adolescents. Cessation behaviors and correlates of past-year quit attempts among smokers were also explored. (Read the full article)

Exposure to second-hand tobacco smoke during pregnancy and infancy has been linked to development of asthma, rhinitis, and eczema in young children. It is unclear whether these risks persist into adolescence.

Exposure to second-hand smoke in utero or during infancy influences the development of allergic disease up to adolescence. Excess risks for asthma and rhinitis were seen primarily in early childhood, whereas those for eczema occurred at later ages. (Read the full article)

The World Health Organization recommends using vaccination contacts to deliver high-dose vitamin A supplementation (VAS) to children aged 6 to 59 months. The effect of this policy on overall child mortality has not been assessed.

In this first randomized controlled trial of VAS at routine vaccination contacts after 6 months, VAS had no overall effect on mortality but was associated with reduced mortality in girls and increased mortality in boys. (Read the full article)

Rates of human papillomavirus (HPV) vaccination lag behind other adolescent vaccines. Research indicates that provider recommendation is the key to improving HPV vaccination rates and that most adolescents who are unvaccinated received other vaccines, indicating missed opportunities for HPV vaccination.

This study explores in-depth the content of provider–patient conversations that either create or prevent opportunities for HPV vaccination. Effective and ineffective conversations are presented with the goal of providing practical tools to improve communication regarding HPV vaccines. (Read the full article)

Growth impairment in sickle disease has been a consistent finding in published reports. Hydroxyurea (HU) decreases vasoocclusive events and increases hemoglobin levels, which may improve growth. However, HU may adversely affect growth in young children by its effect on DNA synthesis.

Height, weight, and head circumference were normal in HU-treated children in the study as compared with the World Health Organization standards. Height, weight, and BMI z scores were similar in placebo and treatment groups. There were no harmful effects of HU on growth. (Read the full article)

Asymptomatic neonatal subdural hemorrhage (SDH) is common, resolves within 4 weeks, and is typically infratentorial or posterior when supratentorial. Subdural hemorrhages may occur after cardiac surgery in infancy. Some hypothesize a causal relationship between hypoxia and SDH in infancy.

Asymptomatic neonatal SDH is often supratentorial and over the convexities. Small infratentorial SDHs may persist for ≤90 days. In young infants with congenital heart disease, an association between hypoxia and SDH could not be demonstrated. (Read the full article)

Pediatric primary care has undergone a cultural shift. Changes in electronic health records, certification requirements, and practice structure have left many physicians feeling too busy to participate in research. Practice-based research networks must adapt to fit the current climate.

Adding quality improvement activities that meet Maintenance of Certification Part 4 criteria to research study design adds value to a practice-based research protocol. This incentive meets the needs of busy physicians, and may help researchers meet study recruitment goals. (Read the full article)

Lung ultrasound outperforms conventional radiology in the emergency diagnosis of pneumothorax and pleural effusions. In the pediatric age, lung ultrasound has been also successfully applied to the fluid-to-air transition after birth and to rapid pneumonia diagnosis.

Nasal ventilation has dramatically decreased the need for invasive mechanical respiratory support. This study demonstrates that, after a short trial on nasal continuous positive airway pressure, lung ultrasonography reliably predicts the failure of noninvasive ventilation unlike the conventional chest radiogram.

Recent reviews suggest that children bullied by siblings are at increased risk of internalizing symptoms. It is not known whether being bullied by a sibling increases risk of psychiatric disorders such as depression, anxiety, and self-harm.

Using a large, community-based birth cohort, we found that being bullied by a sibling is prospectively associated with a doubling in the odds of both depression and self-harm at 18 years in young adults. (Read the full article)

Parental reduced antigen diphtheria-tetanus-acellular pertussis (Tdap) vaccination is difficult to implement, and empirical data on its impact is limited to a single hospital-based study in Texas, which found no reduction in infant pertussis hospitalization.

In New South Wales, Australia, a case-control study found both parents receiving Tdap ≥4 weeks before disease onset was associated with a significant reduction in risk of early infant pertussis and suggestive of persistent protection in subsequent pregnancies. (Read the full article)

Childhood vaccinations mildly increase the risk of febrile seizures in the general pediatric population, during specific risk periods. However, vaccinations are common precipitants for (first) seizures in the genetically determined, fever-sensitive Dravet syndrome (formerly severe myoclonic epilepsy of infancy).

This study shows that in most children with epilepsy onset after vaccination, genetic or structural causes of epilepsy can be identified. This claim includes children with Dravet syndrome (~35%) but also children with benign epilepsy or preexistent encephalopathy. (Read the full article)

Behavioral health (BH) screening is known to increase identification of children with BH issues, but in small-scale studies, rates of follow-up after screening have been reported to be low.

This study examines the relationship between BH screening and the receipt of BH services in Massachusetts Medicaid children. Nearly 60% of children identified with BH problems received BH services, but only 30% of newly identified children received BH services. (Read the full article)

Despite child-resistant packaging requirements for most medications and safe storage education for all medicines, tens of thousands of young children are brought to emergency departments and thousands are hospitalized annually after ingesting prescription medications. Targeted prevention efforts may be needed.

Twelve medications were implicated in nearly half of hospitalizations for prescription medication ingestions. Buprenorphine and clonidine were most commonly implicated and had the highest hospitalization rates when accounting for outpatient use. Prevention efforts should focus on most commonly implicated medications. (Read the full article)

Vaccinating youth is among the nation’s highest health care priorities. Despite proven health benefits, human papillomavirus vaccination rates remain low.

This is the first known study to test whether vaccination of high-risk adolescents is related to their or their parents’ previous knowledge levels. In the results presented, neither parental nor adolescent knowledge is related to subsequent adolescent vaccination. (Read the full article)

Public awareness and usage of physician-rating Web sites have been increasing over the last few years. Such ratings can influence adults’ decisions about choosing a physician, but their influence on decisions for children’s physicians has not been characterized.

In this nationally representative survey of parents, we found that the majority (74%) are aware of rating Web sites and slightly more than one-quarter (28%) had sought information on rating Web sites when choosing a primary care physician for their children. (Read the full article)

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an important risk factor for neonatal jaundice in Nigeria. It is associated with severe hyperbilirubinemia among infants exposed to icterogenic agents. Elevated bilirubin levels have occasionally been demonstrated in G6PD-deficient infants without exposure to icterogenic agents.

Even without exposure to known icterogens, G6PD-deficient infants have a more rapid hematocrit decline and higher bilirubin levels than their G6PD-intermediate and G6PD-normal counterparts throughout the first week of life. (Read the full article)

Continuously aerosolized albuterol been shown to be safe and effective for the treatment of severe status asthmaticus in the emergency department and ICU. Little evidence supports its use in the non–intensive care setting.

With the appropriate resources and support, continuous albuterol may be administered in the non–ICU setting with a low incidence of clinical deterioration and adverse effects. Certain clinical factors may help identify which patients may benefit from higher acuity care. (Read the full article)

School-based health centers (SBHCs) are known to increase access to medical care and mental health services for at-risk adolescents. Policymakers have suggested that SBHCs could function as patient-centered medical homes, but SBHCs have not been evaluated in that context.

Using the constructs of the patient-centered medical home as defined by the American Academy of Pediatrics (accessibility, continuity, comprehensiveness, family-centeredness, coordination, and compassion), this study shows that SBHCs have the potential to function as medical homes from the perspective of adolescents and parents.

The detection of critical congenital heart disease by fetal echocardiography or neonatal physical examination can have limitations. The addition of pulse oximetry screening in the newborn nursery increases the rate of diagnosis of these conditions before hospital discharge.

In a tertiary-care center with comprehensive fetal echocardiography, nearly all newborns with critical congenital heart disease are diagnosed prenatally. Pulse oximetry will identify more infants from settings with lower prenatal detection. Improving access to and training in fetal echocardiography should also improve detection of these conditions.

In 2003, the US Food and Drug Administration issued warnings about hyperglycemia and diabetes with second-generation antipsychotics (SGAs). Since 2004, hyperglycemic and diabetes risk with SGAs has been stated in product labels, and published guidelines have recommended baseline metabolic screening.

Between 2006 and 2011, 11% of children 2 to 18 years starting an SGA had baseline glucose assessed. Youth at risk for diabetes may not be identified. Further, lack of screening impedes determining the contribution of SGAs to hyperglycemia. (Read the full article)

Cross-sectional research indicates that teen sexting is common, may be associated with other adolescent behaviors such as substance use, does not appear to be a marker of mental well being, and is probably an indicator of actual sexual behaviors.

Although mounting evidence links teen sexting to sexual behavior, little is known about the temporal sequencing of these 2 behaviors. Knowing which comes first will aid tween- and teen-focused health care providers in their interaction with patients and patients’ parents. (Read the full article)

Restrictive feeding by parents is associated with poorer eating self-regulation and increased child weight status. However, this association could be due to confounding home environmental or genetic factors that are challenging to control.

Differential maternal restrictive feeding is associated with differences in twins' caloric compensation and BMI z score. Controlling for the shared home environment and partially for genetics, these findings further support a true (ie, unconfounded) association between restriction and childhood obesity.

Movie ratings designed to warn parents about violence and sexual content have permitted increasing amounts of each in popular films. One potential explanation for this "ratings creep" is parental desensitization to this content as it becomes more prevalent in movies.

This study adds experimental evidence that parents become desensitized to movie violence and sex and are more willing to allow children to view such content. (Read the full article)

Jaundiced newborns without additional risk factors rarely develop kernicterus if the total serum bilirubin is <25 mg/dL. Measuring the bilirubin/albumin ratio might improve risk assessment, but the relationships of both indicators to advancing stages of neurotoxicity are poorly documented.

Both total serum bilirubin and bilirubin/albumin ratio are strong predictors of advancing stages of acute and post-treatment auditory and neurologic impairment. However, bilirubin/albumin ratio, adjusted to the same sensitivity, does not improve prediction over total serum bilirubin alone. (Read the full article)

Professional organizations recommend ultrasound as the initial diagnostic imaging modality for children with suspected nephrolithiasis. Computed tomography utilization for children with nephrolithiasis treated at freestanding children’s hospitals is common and varies substantially by hospital.

The high prevalence and regional variability of CT as the first imaging study for children with nephrolithiasis who presented to emergency departments, outpatient clinics, and hospitals throughout the United States indicate that current imaging practices deviate substantially from guidelines.

Delivering competent oral case presentations is an important clinical communication skill, yet effective means of improving trainees’ presentations have not been identified.

Oral presentation feedback sessions facilitated by faculty by using an 18-item competency-based evaluation form early in pediatric clerkships improved medical students’ subsequent oral presentations. Medical schools should consider implementing this evidence-supported practice. (Read the full article)

The population of youth with chronic medical conditions is growing and many attend college. Yet we know little about US colleges’ capacity to identify and care for these youth, nor how transition guidelines and financing models should incorporate college health.

This is the first study to find that although many colleges can provide some clinical care for youth with chronic conditions, few colleges have systems to identify and track these students, elucidating gaps that pediatricians and institutions need to address. (Read the full article)

There are discrepancies regarding which treatment is best in clinical practice for children with parapneumonic empyema, with some authors favoring video-assisted thoracoscopy and others favoring intrapleural fibrinolytic agents.

This study is one of the few randomized clinical trials on this subject in children and the first multicenter trial. It exclusively included patients with septated empyema. Thoracoscopy and fibrinolysis with urokinase were equally effective for this condition. (Read the full article)

In 2000/2001, the American Academy of Pediatrics published recommendations for attention-deficit/hyperactivity disorder (ADHD) care. According to pediatricians’ self-report of adoption of these guidelines, community-based ADHD care appears to be marginally adequate.

Using reviews of >1500 patient charts, this study demonstrates that community-based ADHD care is not consistent with evidence-based practice. Furthermore, variability in much of community-based ADHD care is unrelated to the provider, suggesting that innovative, system-wide interventions are needed to improve ADHD care.

Youth in foster care are at higher risk of health problems at entrance and during their stays in care. Little is known about this group’s risk of health problems in young adulthood, in comparison with other populations of young adults.

This is the first prospective study to our knowledge demonstrating that former foster youth are at higher risk of chronic health problems than economically secure and insecure general population young adults. (Read the full article)

Studies have shown that setbacks, such as receiving low school grades, lead children to experience negative self-feelings (eg, shame, insecurity, powerlessness). Psychological theory predicts that unconditional regard can buffer this adverse impact of setbacks. However, causal evidence is lacking.

This randomized field experiment shows that briefly reflecting on experiences of unconditional regard buffers children’s negative self-feelings after an academic setback 3 weeks later. Unconditional regard may thus be an important psychological lever to reduce negative self-feelings in youth. (Read the full article)

Research suggests that appearance-focused messages and exaggerated depictions of sexual activity in the media negatively influence adolescents’ body and sexual self-perceptions. As adolescents increasingly use the Internet to explore their sexuality, health risks related to online behaviors should be identified.

This 4-wave study examined the prevalence and development of 2 receptive and 2 interactive sex-related online behaviors and their relations with adolescents’ body and sexual self-perceptions. It further investigated which parental strategies regarding Internet use may reduce risky sex-related online behaviors. (Read the full article)

A previous study suggested that physicians in 1 practice network were less likely to diagnose otitis media (OM) and to prescribe broad-spectrum antibiotics for OM for black versus nonblack children.

Nationally, black children with OM are more likely to receive guideline-recommended, narrow-spectrum antibiotics than nonblack children. These findings may reflect inappropriate treatment of OM with the use of broad-spectrum antibiotics in a majority of US children. (Read the full article)

Cyber dating abuse victimization has been correlated with physical, sexual, and psychological adolescent relationship abuse.

This is the first clinic-based study of cyber dating abuse. Forty-one percent of youth reported cyber dating abuse victimization, female more than male respondents. Compared with nonexposed youth, abuse victims reported more sexual assault; female victims reported more contraceptive nonuse and reproductive coercion. (Read the full article)

There is variability in cerebral palsy prevalence estimates in low-resource countries, related to definitions, detection of milder cases, diagnosis age, and adequate training for clinicians. Thus, differences in prevalence and motor patterns between high- and low-resource countries remain unclear.

There were more children with dystonia and less with spasticity in Bangladesh compared with Australia (cerebral palsy diagnosis/motor classifications were consistent between settings). Differences in motor patterns between high- and low-resource countries have profound implications for early detection and appropriate interventions. (Read the full article)

Younger age has been identified as an independent risk factor for all-terrain vehicle (ATV)-related injuries. Since the mid-1980s, one-third of ATV-related deaths have involved children younger than 18 years of age.

Using national data, we found both similarities and differences between pediatric age groups in the contribution of known risk factors to ATV-related deaths. The observed differences suggest the importance of targeting injury prevention approaches to specific age ranges. (Read the full article)

The American Academy of Pediatrics has identified bedding such as pillows, blankets, and quilts as potentially hazardous for the infant sleep environment. Bedding use is a modifiable risk factor for sudden infant death syndrome and unintentional sleep-related suffocation.

Reported bedding use over or under the infant for infant sleep substantially declined from 1993 to 2010. However, about one-half of US infants are still placed to sleep with potentially hazardous bedding despite recommendations against this practice. (Read the full article)

Cesarean delivery has previously been associated with increased risk of specific immune diseases in children. The mechanism remains unknown.

In 1 large population-based cohort, we demonstrate cesarean delivery as a shared risk factor for several immune-related diseases. Such common risk factor suggests early life commonality in the origins of these chronic immune disorders. (Read the full article)

There is a debate about whether e-cigarettes will benefit public health. However, there is little knowledge about how e-cigarette users and dual users (those using both e-cigarettes and tobacco cigarettes) differ from other adolescents on a range of variables.

Teenagers who only used e-cigarettes were intermediate in levels of risk and protective factors between nonusers and those who used both cigarettes and e-cigarettes. This raises a question about whether e-cigarettes recruit low-risk youth to tobacco product use. (Read the full article)

Early diagnosis of LOS in preterm infants may be challenging because of the questionable accuracy of blood culture and the common markers of infections, such as C-reactive protein and procalcitonin.

Our study demonstrated for the first time that P-SEP is an accurate biomarker for the diagnosis of LOS in preterm infants and might contribute to the monitoring of infant response to therapeutic interventions. (Read the full article)

Many population-based studies including pubertal children are based on self-assessment of pubertal maturation, the reliability of which is uncertain.

Self-assessment is not reliable for precise pubertal staging. Simple distinctions between prepuberty and puberty showed moderate agreement with clinical examinations. Parents and girls tended to underestimate and boys to overestimate pubertal development by up to 50% and 30%, respectively. (Read the full article)
