Current human milk fortifiers fail to provide the higher protein intake that is now recommended for feeding human milk–fed infants. There is a desire to avoid the use of powdered products when feeding these infants.

A new ultraconcentrated liquid human milk fortifier that provides more protein than current powdered fortifiers is safe and supports better growth in human milk–fed infants than a powdered fortifier. (Read the full article)

Infants with hypoxic-ischemic encephalopathy suffer a high rate (>40%) of death or moderate to severe disability, even after therapeutic hypothermia. High-dose erythropoietin (Epo) reduces brain injury and improves neurologic function in animal models of neonatal hypoxic-ischemic brain injury.

Multiple doses of Epo (up to 2500 U/kg intravenously) given in conjunction with hypothermia are well tolerated in newborns with HIE. Epo doses of 1000 U/kg intravenously in cooled infants produce plasma concentrations that are neuroprotective in animal studies. (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)

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)

Detained youth represent a vulnerable pediatric population with worse health outcomes than their nondetained peers. To date, little work has been done to determine whether health information technologies may be effectively used to improve the health of this underserved population.

The Internet is accessible to youth involved in the juvenile justice system. A securely accessible online system to store detained youth’s health information may be both feasible and acceptable for engaging these adolescents more actively in their health care. (Read the full article)

The CPT1A p.P479L variant is common to northern aboriginal populations, leads to reduced enzyme activity, and may be associated with increased infant mortality rates.

The p.P479L variant is common in British Columbia First Nations with a coastal distribution correlated with regions of high infant mortality. Homozygotes display an altered acylcarnitine profile and are overrepresented in cases of sudden unexpected infant death in these areas. (Read the full article)

Today’s adolescents increasingly use the Internet to explore their sexual identity. There is public concern that the Internet, because of its accessibility, affordability, and anonymity, stimulates adolescents to engage in online sexual risk behavior (eg, sending sexual images to strangers).

This 4-wave panel study is the first to delineate the typical development of online sexual risk behavior, its relationship with offline sexual risk behavior, and the factors (eg, sensation seeking, family cohesion, life satisfaction, education, online communication) that predict both behaviors.

Mumps outbreaks continue to occur among unvaccinated and highly vaccinated populations. In highly vaccinated populations, options for outbreak control are limited. No previous study has documented the impact of a third measles-mumps-rubella (MMR) vaccine dose on a mumps outbreak.

Our study assessed the use of a third MMR vaccine dose for mumps outbreak control in a setting with preexisting high 2-dose vaccine coverage. The findings suggest a potential role of MMR vaccine for outbreak control in such limited settings. (Read the full article)

Pediatric specialists are increasingly involved in prenatal care, particularly for congenital fetal conditions. Questions remain about pediatricians’ role in the management of maternal conditions that may affect postnatal health, and the attitudes of obstetric and pediatric specialists around such care.

Obstetric and pediatric specialists’ attitudes differ substantially regarding pediatricians’ role in providing consultation for maternal conditions that may affect a child’s health postnatally, and regarding whether court authorization may be appropriate when a woman refuses certain treatment recommendations.

High doses of radiation have been linked to cancer induction in irradiated populations such as atomic bomb survivors. Medical imaging directs significant radiation doses to human tissues. Epidemiological studies have demonstrated that children are more sensitive to radiation than adults.

The link between cancer induction from moderate radiation doses such as diagnostic imaging is controversial. This study uses Food and Drug Administration–accepted formulas to calculate theoretical risk of breast cancer induction in female pediatric trauma patients receiving diagnostic imaging of the thoracic spine.

Prenatal cocaine exposure is associated with the trajectories of childhood behavior problems. Exposure effects may also be related to maternal use of other substances during pregnancy, and risk factors other than prenatal exposure may augment the detrimental cocaine effects.

The balance between cumulative risk and protective indexes predicts behavior outcomes, independent of prenatal drug exposure. A high protective index even with a high level of risks can mitigate the detrimental effects of drug exposure on behavior problem trajectory. (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.

First drink before age 15 greatly increases the likelihood for later alcohol abuse or dependence. Separate investigations have linked many variables to alcohol initiation, but few have attempted to identify the optimal combination of predictors for age of alcohol initiation.

This article supports the screening questions selected in the joint National Institute on Alcohol Abuse and Alcoholism and the American Academy of Pediatrics initiative to identify and initiate intervention in youth at risk for early use of alcohol. (Read the full article)

Complementary and alternative medicine (CAM) use is common among children, especially those with chronic, recurrent, or incurable conditions. Concurrent use of CAM with conventional medications is of concern and needs to be assessed, especially in vulnerable patient populations.

CAM use is high among pediatric cardiology, gastroenterology, neurology, oncology, and respiratory patients, most of whom use CAM concurrently with conventional care. This study provides additional evidence to suggest the use of CAM be included in routine patient history taking. (Read the full article)

The American Academy of Pediatrics recommends that infants <1500 g birth weight receive an iron intake of 4 mg/kg per day. There are no randomized trials to support this recommendation.

This trial compared the effect of iron supplementation of 2 mg/kg per day on the hematocrit at 36 weeks' postmenstrual age. This study concluded that iron supplementation does not affect the 36-week hematocrit or the number of transfusions in infants <1500 g. (Read the full article)

A number of studies have shown that home-visiting interventions can improve outcomes for children being raised in families that face multiple adversities. It is less clear how well these benefits are sustained over long periods.

The current study shows that the Early Start program of home visitation has benefits in terms of reducing child abuse, increasing parental competence, and improving childhood behavioral adjustment for up to 9 years, suggesting long-term benefits of home visitation. (Read the full article)

Practice characteristics, such as practice size, have been associated with the readiness of adult primary care practices for medical home certification. Little is known about how ready primary care practices for children are for medical home certification.

Primary care practices for children attained only 38% of the infrastructure required for medical home certification. Smaller practice size was significantly associated with lower infrastructure scores. Medical home programs need effective approaches to support practices with limited resources.

Provider training level is associated with lower rates of successful tracheal intubation in selected neonatal settings. However, little is known about the association of training level with tracheal intubation success and adverse events in the PICU.

Our results demonstrate the association of training level on the first attempt and overall success rate as well as the incidence of adverse tracheal intubation–associated events in a large-scale, prospective assessment across 15 academic PICUs. (Read the full article)

There is a lack of consensus regarding the optimal investigative approach after a first febrile urinary tract infection. This is because of uncertainty regarding the long-term clinical significance of vesicoureteral reflux and urinary tract infection–related renal scarring.

No ideal diagnostic algorithm exists. We found marked variability in sensitivity and specificity for detection of abnormalities using current protocols. We also highlight the considerable cost differences, both financially and in terms of radiation dose, of different protocols. (Read the full article)

In Mexico, substantial declines in childhood diarrhea deaths have been documented since the introduction of the rotavirus vaccine in 2007. However, there is concern of lower vaccine effectiveness in less developed regions of Mexico with higher diarrhea-related mortality.

We documented significant and comparable declines across all 3 regions of Mexico with different levels of development, indicating equitable vaccine distribution to children with varying risk of mortality and reaffirming the beneficial effects of rotavirus vaccination against fatal diarrheal disease.

Although it is known that relatively minor abusive injuries sometimes precede more severe physical abuse, the prevalence of these previous injuries in infants evaluated for abuse was not known.

A history of bruising or oral injury in a precruising infant evaluated for abuse should heighten the level of suspicion because these injuries are common in abused infants and rare in infants found not to be abused. (Read the full article)

Expectations are high that electronic health record–based clinical decision support and performance feedback will improve adherence to guidelines by delivering relevant and actionable information to clinicians. Few studies have evaluated these assertions or examined the combined effects of decision support and feedback.

Clinical decision support customized to a patient’s history and presentation and performance feedback are both effective for improving adherence to guidelines for otitis media. However, the combination of the 2 interventions is no better than either delivered alone. (Read the full article)

Acquired widespread pain syndromes of youth are prevalent, disabling, usually unexplained, and untreatable. Small-fiber polyneuropathy causes widespread pain and multisystem complaints in older adults. Some causes are treatable. Neurodiagnostic skin biopsy, autonomic function testing, and nerve biopsy permit objective diagnosis.

It identifies definite (in 59%) and probable (in 17%) small-fiber polyneuropathy among 41 young patients with otherwise-unexplained, childhood-onset widespread pain. It characterizes this new disease’s clinical features, diagnostic, and treatment options. Some cases appeared immune mediated and responded to immunomodulatory therapies. (Read the full article)

Chlorhexidine cleansing of the cord can reduce mortality in high-risk settings. Time to separation may increase with topical applications of chlorhexidine; 1 previous community trial quantified this increase and did not measure whether caretakers perceived the delay.

Single and multiple cleansing of the umbilical cord increases time to separation by ~50%, or an average of 2 to 2.5 days. Caretakers were able to detect this difference and expressed dissatisfaction, while still accepting the intervention. (Read the full article)

In the only previous cross-sectional study, the quality of pediatric guidelines was rated low on the AGREE-II (Appraisal of Guidelines for Research and Evaluation II) scale. The levels of evidence used in pediatric clinical practice guidelines have never been described.

American Academy of Pediatrics guidelines score low on the AGREE-II scale. Approximately one-quarter of recommendations are based on expert opinion or no reference. These findings support the adoption of standards for guideline development and research targeted toward unsupported recommendations. (Read the full article)

Varicella vaccine is known to be highly effective, with added benefit from a second dose.

This study demonstrates the lasting effectiveness of varicella vaccine and the benefit of the second dose. Breakthrough varicella occurred soon after vaccination, varicella rates did not increase over 14 years, and there was no increase in zoster in the cohort. (Read the full article)

Despite proven health benefits, human papillomavirus (HPV) vaccination rates are among the lowest of all routine immunizations. No previous large-scale trial has compared the benefit of automated decision support directed at clinicians, families, or both in any context.

We found that a clinician-focused intervention was most effective for initiating the HPV vaccine series, whereas a family-focused intervention supported completion. Decision support directed at both clinicians and families most effectively promotes HPV vaccine series receipt. (Read the full article)

A low-level risk of intussusception after rotavirus vaccines, ~1 to 2 cases per 100 000 vaccinees, exists in some settings. In the United States, a risk of 1 in 65 000 was excluded, but lower risk could exist.

A persistent clustering of intussusception events 3 to 6 days after dose 1 indicates the possibility of a low-level risk of intussusception of ~0.8 cases per 100 000 vaccinees. The documented benefits of rotavirus vaccine far outweigh this low-level risk of intussusception. (Read the full article)

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

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

The United States switched from whole-cell to acellular pertussis vaccines during the 1990s. Whether pertussis risk during a California outbreak differed between teenagers who previously received whole-cell or acellular pertussis vaccines early in life has not been reported.

We evaluated pertussis risk in 10 to 17 year olds at Kaiser Permanente Northern California during a recent pertussis outbreak. Those given whole-cell pertussis vaccines in childhood were more protected than those given acellular pertussis vaccines. (Read the full article)

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

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

The ideal management of children with vesicoureteral reflux (VUR) remains a source of debate. There is little evidence to support many of the current management practices for children with VUR who have had 1 or 2 urinary tract infections.

Baseline associations, including bladder and bowel dysfunction and imaging studies, from the largest randomized, controlled trial conducted to date aimed at assessing the value of antimicrobial prophylaxis in children with urinary tract infection and VUR are presented. (Read the full article)

Cognitive and behavioral problems after pediatric traumatic brain injury lead to poor functioning across multiple settings and can persist long-term after injury. Executive dysfunction is particularly common; however, there is a paucity of evidence-based interventions to guide treatment.

This study is among the largest randomized controlled trials performed in pediatric traumatic brain injury. It demonstrates the ability to use an online problem-solving-based intervention to improve caregiver ratings of executive dysfunction within 12 months after injury. (Read the full article)

Monovalent rotavirus vaccine was introduced for infants in the United States in 2008. Previous US evaluations have not specifically assessed the performance of this vaccine under routine use.

Using the same methodology and covering the same time period, high effectiveness (~90%) was demonstrated for the monovalent and the pentavalent rotavirus vaccine series against rotavirus disease resulting in emergency department/inpatient care, in children up to 2 years of age. (Read the full article)

Pneumococcal conjugate vaccines are effective in preventing pneumococcal disease but are also costly. Although the current US immunization schedule recommends 4 doses, many countries have adopted 3-dose schedules that have worked well, but may provide less protection against pneumococcal disease.

Changing the US 13-valent pneumococcal conjugate vaccine schedule from 3 to 2 primary doses while keeping a booster dose would save $412 million annually but might lead to moderate increases in pneumococcal disease, especially otitis media and pneumonia. (Read the full article)

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

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

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

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

Previous studies have shown that nonmedical exemptions (NMEs) to immunization cluster geographically and contribute to outbreaks of vaccine-preventable diseases such as pertussis. The 2010 pertussis resurgence in California has been widely attributed to waning immunity from acellular pertussis vaccines.

This study provides evidence of spatial and temporal clustering of NMEs and clustering of pertussis cases and suggests that geographic areas with high NME rates were also associated with high rates of pertussis in California in 2010. (Read the full article)

The 1-dose childhood varicella vaccination program in the United States resulted in dramatic declines in varicella incidence, hospitalizations, and deaths. There is little information on the impact of the 2006 recommendation for 2-dose varicella vaccination of children on varicella epidemiology.

In the first 5 years of the 2-dose varicella vaccination program, declines in varicella incidence were seen in all age groups, including infants who are not eligible for varicella vaccination, providing evidence of the benefit of high population immunity. (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)

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)

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)

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)

Prenatal and postnatal organophosphate (cholinesterase inhibitor) pesticide exposure has been associated with delays in attention, memory, intelligence, and inhibitory control. Two recent studies reported decreased attention and working memory with greater exposure to organophosphates in boys but not in girls.

This is the first study to report associations between decreased acetylcholinesterase activity, a stable marker of cholinesterase inhibitor pesticide exposure, and lower overall neurodevelopment, attention, inhibitory control, and memory. These associations were present in boys but not in girls. (Read the full article)

Medication errors occur frequently among pediatric patients, particularly those treated in rural emergency departments (EDs). Although telemedicine has been proposed as a potential solution, there are few data supporting its clinical effectiveness and its effect on medication errors.

The use of telemedicine to provide pediatric critical care consultations to rural EDs is associated with less frequent physician-related ED medication errors among seriously ill and injured children. Therefore, this model of care may improve patient safety in rural hospital EDs. (Read the full article)

Bronchiolitis is a leading cause of hospitalization for children, yet variability in its management persists. To promote evidence-based care, the American Academy of Pediatrics published practice guidelines in 2006 that advocate primarily supportive care for this self-limited disease.

Since publication of the guidelines in 2006, few studies have evaluated their impact on diagnostic testing and treatment. This study documents positive changes in resource use among hospitalized patients with bronchiolitis over an 8-year period. (Read the full article)

Hypertonic saline (3% and 5%), has been shown to improve clinical severity scores and reduce inpatient length of stay, and was associated with a trend toward lower admission rate in acute bronchiolitis.

We are not aware of any previous data using 7% hypertonic saline in bronchiolitis. Our results suggest that 7% saline does not lower clinical severity of illness, admission rate, or length of stay, when compared with normal saline. (Read the full article)

Major depression is common among adolescents. The PHQ-9 has good sensitivity and specificity for detecting depression among adolescents in primary care settings. However, no study has examined the psychometric properties of the PHQ-9 among Chinese adolescents in school settings.

This is the first study to validate the use of the PHQ-9, Patient Health Questionnaire–2 item, and Patient Health Questionnaire–1 item among Chinese adolescents in Taiwan. The PHQ-9 and its 2 subscales have good sensitivity and specificity for detecting depression among school adolescents. (Read the full article)

An algorithm for neonatal early-onset sepsis risk based on Centers for Disease Control and Prevention 2002 guidelines for prevention of perinatal Group B Streptococcus disease results in the evaluation of ~12–15% of well-appearing term and late preterm infants.

A revised algorithm based on the Centers for Disease Control and Prevention 2010 guidelines eliminated 25% of all early-onset sepsis evaluations and resulted in significant cost savings, without short-term evidence of harm. (Read the full article)
