Clinical decisions must be medically necessary to be approved by insurers. There is a federally mandated medical necessity standard for children in Medicaid, but not in private plans. American Academy of Pediatrics policy calls on pediatricians to help define pediatric medical necessity.

This study reviewed pediatric medical necessity definitions in Medicaid state statutes, regulations, and provider manuals. The federal standard was not replicated on all levels, and provider manuals were least likely to have it. Pediatricians should engage in defining pediatric standards. (Read the full article)

Recent concussion research has examined the role of impact location (ie, the area on the head to which impact occurred); however, no studies exist regarding impact location’s association with concussion outcomes (eg, symptomatology, symptom resolution time, return to play).

This study is the first to examine the association of impact location and concussion outcomes in young athletes. Our findings suggest that impact location, as assessed by sideline observers/player report, is likely of little use in predicting clinical outcomes. (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)

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)

With the publication of evidence-based guidelines for asthma, bronchiolitis, and pneumonia, numerous efforts have been made to standardize and improve the quality of care. However, despite these guidelines, variation in care exists.

This study establishes clinically achievable benchmarks of care for asthma, bronchiolitis, and pneumonia. Using a published method for achievable benchmarks of care, we calculated average utilization among the high-performers, which can serve as achievable goals for local quality improvement.

Vitamin K prophylaxis at birth is an effective intervention for preventing vitamin K deficiency bleeding.

Refusal of vitamin K is not common, but those who refuse are more likely to have a birth attended by a midwife, and deliver at home or in a birth center. They are also less likely to immunize their child. (Read the full article)

Messages emphasizing societal benefits of vaccines have been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children.

Findings suggest that health care providers should emphasize the direct benefits of MMR vaccination to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child. (Read the full article)

Urinary tract infection is the most common serious bacterial illness among febrile infants and young children. Automated urine cytometry may supplant traditional urinalysis, but diagnostic performance at unique pediatric cutpoints has not been described for this labor-saving technique.

We describe new, clinically useful cutpoints for automated leukocyte and bacterial counts. The sensitivity and specificity of bacterial counts ≥250 cells/μL exceed those of other methods. However, point-of-care dipstick tests for leukocyte esterase or nitrite have acceptable performance. (Read the full article)

Among US youth 6 to 15 years of age there are differences in strength by gender and age. Little is known about differences in strength by weight status in the US pediatric population.

This study provides current US nationally representative reference values for 4 measures of strength in youth 6 to 15 years old. Body weight was associated with strength, but the association varied depending upon the measure. (Read the full article)

Cardiovascular risk begins in childhood. New clinical guidelines established a care strategy for lowering risks. Incorporation of guidelines into routine practice lags due to barriers related to knowledge and attitudes about guidelines, as well as behaviors of practitioners, patients, and clinical systems.

This study demonstrated that a multifaceted approach including tools, education, and support for changes in practice systems can accelerate the adoption of guidelines during routine pediatric well-child visits, compared with dissemination of the guidelines alone. (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)

Overweight and peer victimization are common in childhood and negatively affect health and well-being. Overweight may predispose children to peer victimization, but whether adiposity also increases the risk of bullying perpetration is unclear.

A high BMI at school entry predicts bullying involvement, according to reports of teachers and children themselves. Although trends were visible across the whole BMI spectrum, particularly obese children were victimized and likely to be bully perpetrators. (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)

The fetal origins of adult disease hypothesis proposes that suboptimal fetal development may condition the later risk of disease, particularly cardiovascular disease. However, this hypothesis has never been tested for diseases of the aging brain.

This first study of its kind provides clinical measures suggesting that small birth size, as an indicator of an adverse intrauterine environment, has lifelong consequences for brain tissue volume and cognitive function. In addition, it shows that the effects of a suboptimal intrauterine environment on late-life cognitive function were particularly present in those with lower educational levels. (Read the full article)

Stimulant medications are indicated for treatment of childhood attention-deficit/hyperactivity disorder (ADHD), but there is concern that stimulants may negatively affect growth. However, no longitudinal, population-based studies have examined height into adulthood for childhood ADHD cases.

This longitudinal, population-based study shows that neither childhood ADHD itself nor treatment with stimulants is associated with significant deficits in height into adulthood. (Read the full article)

Being bullied can lead to adverse physical and mental health outcomes. Individuals who experience a sudden traumatic event often have short-term disturbances in their sleep patterns. Ongoing trauma may result in extended periods of sleep disruption.

Being bullied in elementary school predicts parasomnias, such as nightmares and night terrors, years later. General practitioners, pediatricians, parents, and teachers may consider parasomnias as potential signs of being bullied. (Read the full article)

Asthma and food allergy are common chronic conditions impacting 14% and 8% of US school-aged children, respectively. School districts must be prepared to track students who have these conditions to ensure proper daily management and emergency response.

This study examines the demographic distribution of asthma and food allergy and the existence of school health management plans in a large, urban school district. The findings show that school health management plans are underused for both conditions. (Read the full article)

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)

Partner violence victimization is associated with mental and behavioral health effects linked to weight gain. Childhood maltreatment is directly linked to obesity and associated with neuroanatomic and psychosocial changes, which heighten vulnerability to subsequent stressors.

This study finds that dating violence victimization is associated with greater increases in BMI from adolescence to young adulthood among women. Women with previous exposure to childhood sexual abuse are especially vulnerable to dating violence–related increases in BMI. (Read the full article)

Puberty suppression has rapidly become part of the standard clinical management protocols for transgender adolescents. To date, there is only limited evidence for the long-term effectiveness of this approach after gender reassignment (cross-sex hormones and surgery).

In young adulthood, gender dysphoria had resolved, psychological functioning had steadily improved, and well-being was comparable to same-age peers. The clinical protocol including puberty suppression had provided these formerly gender-dysphoric youth the opportunity to develop into well-functioning young adults. (Read the full article)

Cancer continues to be the leading disease-related cause of death among children and adolescents in the United States. More information is needed about recent trends.

This study provides recent, robust data supporting the increasing incidence of pediatric thyroid cancer and rising overall cancer rates among African American children and adolescents and is the first study to describe increasing rates of pediatric renal carcinoma. (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)

Many pediatric acute respiratory tract infections (ARTI) are viral and do not require antimicrobial treatment. Recent estimates of antimicrobial overprescribing for these infections, defined based on the published bacterial disease prevalence among all ARTI, are not available.

Based on the published bacterial prevalence rates for pediatric ARTI, antimicrobial agents are prescribed almost twice as often as expected to outpatients nationally, amounting to an estimated 11.4 million potentially preventable antimicrobial prescriptions annually. (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)

Evidence from cohort studies has consistently found that universal bilirubin screening is associated with reductions in rates of severe hyperbilirubinemia but has shown variation in other outcomes such as phototherapy use, length of stay, emergency department visits, and readmission rates.

Universal bilirubin screening may not increase neonatal length of stay or postdischarge hospital use. Preexisting trends in health care utilization have an impact on observed effects of universal bilirubin screening. (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)

Childhood immunization might contribute to an increase in asthma prevalence. Previous studies have been contradictory, and many lack sufficiently large control groups of nonimmunized children.

Pertussis immunization in infancy does not increase the risk of asthma medication in adolescents. Our study presents convincing evidence that pertussis immunization in early childhood can be considered safe with respect to long-term development of asthma. (Read the full article)

The single-family room (SFR) NICU is a major response to improve care and reduce developmental morbidity in preterm infants. However, no studies have examined how and why this model is associated with changes in medical and neurobehavioral outcome.

This study shows improved medical and neurodevelopmental outcome in infants hospitalized in the SFR model of care. More important, improvements occurred specifically in relation to increases in maternal involvement and developmental support afforded by the SFR environment. (Read the full article)

In HIV-infected children, decisions to start antiretroviral therapy must weigh immunologic benefits against potential risks. Current guidelines recommend using CD4 percentage and age when deciding to start treatment. Population-level effects of these factors on immunologic recovery are unknown.

Starting antiretroviral therapy at higher CD4 percentages and younger ages maximizes potential for immunologic recovery. However, not all benefits are sustained, and viral failure may occur. Our results help clinicians better weigh immunologic benefits against viral failure risks. (Read the full article)

More than 200 million children <5 years old in low- and middle-income countries are not reaching their potential in cognitive development because of factors associated with poverty.

Poverty affects children’s cognition as early as 7 months and continues to increase until 5 years of age. It is mainly mediated by parental education, birth weight, home stimulation throughout the 5 years, and growth in the first 24 months. (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)

Physical activity programs have been shown to have positive implications for children’s cognitive performance and brain structure and function. However, additional randomized controlled trials are needed to determine whether daily physical activity influences executive control and its neural underpinnings.

The randomized controlled trial, designed to meet daily physical activity recommendations, used behavioral and electrophysiological measures of brain function to demonstrate enhanced attentional inhibition and cognitive flexibility among prepubertal children. (Read the full article)

Admissions to the ICU during off-hours (nights and weekends) have been variably associated with increased mortality in both adults and children. Changes in staffing patterns, patient characteristics, or other factors may have influenced this relationship over time.

This study demonstrates in a large, current, multicenter database sample that off-hours admissions to PICUs are not associated with increased risk-adjusted mortality. Admissions in the morning from 6:00 am to 10:59 am are associated with increased mortality and warrant further attention. (Read the full article)

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.

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)

Family meals are protective for child health, but there are inconsistent findings in relation to child weight status. More research is needed examining why family meals are protective for child health and whether there are differences by child weight status.

The current mixed-methods study used direct observational methods to examine family dynamics during family meals and child weight status. Results indicated that positive family interpersonal and food-related dynamics during family meals were associated with reduced prevalence of childhood obesity. (Read the full article)

Little is known about how pediatricians communicate with overweight Latino children and their parents regarding overweight and obesity.

Findings suggest that many overweight Latino children and their parents do not receive direct communication that the child is overweight, weight-management plans, culturally relevant dietary recommendations, or follow-up visits. (Read the full article)

Sleeping on a sofa increases the risk of sudden and unexpected infant death.

Infant deaths on sofas are associated with nonsupine placement, being found in side position, surface sharing, changing sleep location, and experiencing prenatal tobacco exposure. These results may help explain why sofa sleeping is hazardous for infants. (Read the full article)

Allostatic load (AL), a biomarker of cardiometabolic risk, predicts the onset of the chronic diseases of aging including cardiac disease, diabetes, hypertension, and stroke. Socioeconomic-related stressors, such as low family income, are associated with AL.

African American youth who grow up in neighborhoods in which poverty levels increase across adolescence evince high AL. The study also highlights the benefits of emotional support in ameliorating this association. (Read the full article)

Despite breastfeeding recommendations by the World Health Organization and the American Academy of Pediatrics, there is less agreement on appropriate use of infant solid foods. There are currently no well-established dietary guidelines for US infants that are similar to the Dietary Guidelines for Americans (aged >2 years).

Distinct dietary patterns exist among US infants and have differential influences on growth. Use of "Infant guideline solids" (vegetables, fruits, baby cereal, and meat) with prolonged breastfeeding is a promising healthy dietary pattern for infants after age 6 months. (Read the full article)

Earlier adiposity rebound may increase fatness in later life; however, there is limited evidence from large cohorts of contemporary children with direct measures of fatness in adolescence or adulthood.

Early adiposity rebound is strongly associated with increased BMI and fatness in adolescence. Future preventive interventions should consider targeting early childhood to delay timing of adiposity rebound. (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. (Read the full article)

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)

Phototherapy decreases bilirubin concentration in skin more rapidly than in blood. During and after phototherapy, transcutaneous bilirubin measurements are considered unreliable and therefore discouraged.

Transcutaneous bilirubin underestimates total serum bilirubin by 2.4 mg/dL (SD, 2.1 mg/dL) during the first 8 hours after phototherapy. This gives a safety margin of ~7 mg/dL below the treatment threshold to omit confirmatory blood sampling. (Read the full article)

Direct antiglobulin titer (DAT) positive, blood group A or B newborns born to group O mothers have a high incidence of hyperbilirubinemia, attributable to increased hemolysis.

DAT ++ readings were associated with a higher incidence of hyperbilirubinemia and a greater degree of hemolysis than DAT ± or DAT + counterparts. DAT strength should be taken into consideration when planning treatment strategies or follow-up of ABO-heterospecific newborns. (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)
