Impaired visual development has been reported in infants born to mothers prescribed methadone in pregnancy. Immature visual evoked potentials have been reported in this population, but data were confounded by gestation, growth restriction, and illicit drug use.

Visual evoked potentials are small and immature in infants exposed to methadone and other drugs of misuse in utero. These changes are independently associated with methadone exposure and persist after controlling for gestation, socioeconomic deprivation, alcohol consumption, and cigarette smoking.

Most studies focus on health of foster children or local samples of young children. One previous study examined a national cohort longitudinally but did not address the full age group or range of conditions at the time of initial investigation.

Using 2 approaches to assess children (aged 0–17.5 years) who have chronic health conditions, we found that regardless of placement, investigated children had much higher rates of these conditions than the general population at the time of initial assessment. (Read the full article)

Reasons mothers cite for breastfeeding cessation vary across an infant's first year of life; however, once women stop breastfeeding, little is known about whether they breastfed as long as they desired or reasons why they did not meet their desired duration.

About 60% of mothers do not meet their desired breastfeeding duration. Mothers who do not breastfeed as long as they desire primarily cite concerns about maternal or child health and processes associated with breastfeeding as their reason to stop breastfeeding. (Read the full article)

The presence of elevated cardiometabolic risk factors, such as obesity, high glucose or lipid levels, and smoking, in adolescents has been shown to be associated with earlier onset of chronic conditions, such as diabetes and heart disease.

Obesity, smoking, and elevated glucose increases the risk of dying before the age of 55 years. This is the first study to focus on risk factors and mortality among adolescents and young adults in a nationally representative US sample. (Read the full article)

Children have been shown to imitate behaviors they see on screen.

Modifying what children watch can improve their observed behavior. (Read the full article)

Children with Lyme and septic arthritis of the knee may present similarly, although septic arthritis requires prompt treatment initiation to avoid joint destruction. Clinicians must make initial management decisions without Lyme serology and bacterial culture results.

Our clinical prediction rule accurately identified patients at low risk for septic arthritis in a Lyme disease–endemic area. In the appropriate clinical context, low-risk patients may be spared invasive testing such as diagnostic arthrocentesis. (Read the full article)

Trigger scores and early warning systems provide an objective measure of a patient’s condition, allowing earlier recognition of severe illness and adaptation of care. Such scores are established in adult and pediatric populations but remain unevaluated and rarely used in neonates.

This newly designed Neonatal Trigger Score provides an objective adjunct to multidisciplinary clinical assessment in detecting unwell neonates. It is more sensitive and specific than previously validated pediatric early warning system scores. (Read the full article)

Celiac disease is increasing in several countries and has emerged as a public health problem. Infant feeding has been suggested to affect celiac disease development and/or clinical expression. However, evidence-based complementary feeding strategies are limited.

Significant difference in celiac disease prevalence between 2 cohorts of 12-year-olds indicates an option for disease prevention. The cohorts differed in infant feeding, and our findings suggest that gradual introduction of gluten in small amounts during ongoing breastfeeding is favorable. (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)

UV radiation exposure in tanning beds is associated with an increased risk of skin cancer. Because of the rising rate of melanoma, the World Health Organization recommends that persons <18 years of age not use tanning devices.

Despite scientific evidence to the contrary, tanning facilities in Missouri, a state without indoor-tanning regulations, often misinformed consumers regarding the risk of skin cancer and would allow children as young as 10 years old to use tanning devices. (Read the full article)

Studies of clinically derived samples of infants with failure to thrive have reported that children remain shorter and lighter than their peers at school-age. Enhanced weight gain ("catch-up") in small infants has been linked to subsequent obesity.

Infants with early weight faltering caught up in weight by 2 years, but height gain remained disproportionally slow. Those with weight faltering later in infancy remained shorter and lighter throughout childhood. Anthropometric outcomes of both groups were within population norms at 13 years.

Failure to thrive (FTT) is a common and vexing pediatric problem. Evaluation has historically involved large batteries of tests, multiple consultations, radiologic studies, and prolonged hospital admissions, resulting in significant costs and inconsistent results.

Scheduled failure to thrive (FTT) admissions on weekends result in increased lengths of stay and health care costs compared with weekday admissions of similar levels of complexity. Reduction in planned weekend admissions for FTT could significantly reduce health care costs. (Read the full article)

Of more than 2 million children infected with HIV, almost 90% live in resource-limited settings where pediatric HIV care is often suboptimal. Implementing electronic health records with computerized decision support offers a potential tool for improving care.

This randomized, controlled trial demonstrates that computer-generated clinical reminders can significantly improve clinician compliance with HIV care guidelines for children in a resource-limited setting. This intervention is scalable as developing countries implement electronic health record systems. (Read the full article)

The Supplemental Nutrition Assistance Program (SNAP) is the largest federal nutrition assistance program. Studies among adults suggest that SNAP participation may be associated with suboptimal diets. Few studies have extensively examined these associations among children.

SNAP participation was not associated with childhood obesity. SNAP children consumed diets poorer in some aspects than nonparticipants, but intake of some micronutrients was higher. The diets of both groups of low-income children were far from meeting dietary guidelines. (Read the full article)

Prenatal alcohol exposure causes a continuum of effects. The most severe phenotype, fetal alcohol syndrome, involves facial dysmorphism, growth deficits, and neurocognitive problems. The classic facial characteristics include short palpebral fissures, smooth philtrum, and thin upper vermillion.

This study develops novel strategies to help detect facial dysmorphism across the fetal alcohol spectrum, especially in children with heavy alcohol exposure but without classic facial characteristics. The methods show potential for identifying which of these children are cognitively affected. (Read the full article)

Pediatric training programs use simulation for procedural skills training. Research demonstrates student satisfaction with simulation training, improved confidence, and improved skills when retested on a simulator. Few studies, however, have investigated the clinical impact of simulation education.

This is the first multicenter, randomized trial to evaluate the impact of simulation-based mastery learning on clinical procedural performance in pediatrics. A single simulation-based training session was not sufficient to improve interns’ clinical procedural performance. (Read the full article)

Reductions in infant mortality in the 20th century have not continued. Racial and socioeconomic inequalities in both infant mortality and sudden infant death syndrome (SIDS) persist. Rates of infant mortality in English-speaking countries are higher than the Organisation for Economic Co-operation and Development average.

At least 16.4% of SIDS and 3.4% of infant deaths not classified as SIDS are attributable to maternal alcohol use. Maternal alcohol-use disorder increases the risk of infant mortality through direct effects on the fetus and indirectly through environmental risk factors. (Read the full article)

Skin and soft tissue infections (SSTIs) are a common pediatric condition often requiring inpatient management. Several studies describe recent increases in hospitalizations due to SSTIs.

In addition to rising hospitalizations, analysis of pediatric SSTI resource utilization trends revealed a twofold increase in incisions and drainages over a 13-year period. A growing number of incisions and drainages were performed in younger children. (Read the full article)

Children with acute liver failure due to a single-dose acetaminophen exposure have a characteristic liver biochemistry profile of low conjugated bilirubin and high alanine aminotransferase, which is associated with a favorable clinical outcome when treated with N-acetylcysteine.

Children with acute liver failure associated with chronic acetaminophen exposure also have a similar liver biochemistry profile, but for unknown reasons, they have a poorer clinical outcome than patients with single-dose acetaminophen exposure. (Read the full article)

Guidelines encourage pediatric health care providers to aid in identifying women with postpartum depression but not postpartum anxiety, yet the major life event of childbirth can be anxiety provoking for many women.

During the postpartum hospital stay, anxiety was far more common than depression among breastfeeding women. Anxiety remained more common for the 6 months after childbirth, and was associated with increased health care use and reduced breastfeeding duration, particularly among primiparous women.

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.

The triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) estimates atherogenic small, dense low-density lipoprotein cholesterol and predicts arterial stiffness and hard cardiovascular events in adults. Whether TG/HDL-C predicts intermediate noninvasive end points (arterial stiffness) in youth is not known.

This study is the first to document stiffer vessels in youth with higher cardiovascular risk factor–adjusted TG/HDL-C, with the effect especially strong in obese subjects. Evaluating TG/HDL-C may be helpful in identifying young subjects at risk for obesity-related atherosclerosis. (Read the full article)

While obesity-promoting eating, sedentary and physical activity behaviors, and increased prevalence of adiposity are evident from early life, few high-quality studies have evaluated interventions that seek to influence the development of these behaviors in very early childhood.

This study highlights the receptivity of first-time parents to interventions focused on their new infant’s eating and active play and provides evidence of effectiveness on some obesity-promoting behaviors in very early childhood. (Read the full article)

Children with sickle cell disease (SCD) have a higher basal metabolic rate, and have historically been underweight. In the general pediatric population, the average BMI percentile has been rising over the past 2 decades.

BMI percentiles for children with SCD in New England are higher than historically reported, mimicking the weight status in the general pediatric population. In children with SCD, higher hemoglobin levels increased the odds of being overweight and obese. (Read the full article)

Autism is a disorder that significantly affects language/communication skills, with many children not developing fluent language. The rate of spoken language acquisition after severe language delay and predictors of functional language, beyond comorbid intellectual disability, is less clear.

This study uses the largest sample to date to examine the relationship between key deficits associated with autism and attainment of phrase and/or fluent speech after a severe language delay, providing information to guide therapeutic targets and developmental expectations. (Read the full article)

Despite high coverage with acellular pertussis vaccine (DTaP), rates of pertussis have increased substantially in 7- to 10-year-olds in recent years. Duration of protection with 5 doses of DTaP may wane earlier than expected and is currently not well described.

This evaluation reports increasing risk of pertussis in the 6 years after receipt of the fifth DTaP dose, suggesting that waning of vaccine-induced immunity is occurring before the recommended adolescent booster dose at 11 to 12 years of age. (Read the full article)

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)

Although the metabolic syndrome is associated with obesity, not all obese children have insulin resistance and metabolic syndrome, and nonobese children may develop these abnormalities. Associated factors have not been well described.

There was a 6.6% prevalence of nonobese children who were insulin-resistant, associated with a family history of hypertension. There was a 21.3% prevalence of obese who were not insulin-resistant, associated with a low waist circumference. (Read the full article)

Although amphibians are known Salmonella carriers, aquatic African dwarf frogs are specifically marketed toward children, who are especially vulnerable to Salmonella infections. Both direct animal contact and indirect contact with animal habitats can lead to human Salmonella infections.

This is the first reported outbreak of human Salmonella infections associated with African dwarf frogs, particularly among young children. Parents should be aware of the risk of Salmonella infections from both direct and indirect animal contact. Pediatricians should regularly inquire about animal contact and advise families about risks.

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)

Accurately identifying ill hospitalized children with vital signs concerning for clinical deterioration is fundamental to inpatient pediatrics. Normal vital sign ranges for healthy children are useful for outpatient practice but have limited application to detecting deterioration in the hospital setting.

Percentile curves for heart and respiratory rate in hospitalized children were developed and validated. The distributions differed from existing reference ranges and early warning scores. They may be useful to identify vital signs deviating from ranges expected among hospitalized children. (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)

Baby-Friendly Hospital Initiative (BFHI) accreditation can have a positive effect on breastfeeding initiation and continuation rates; however, little is known about the effect of BFHI accreditation in populations with high breastfeeding-initiation rates and where infant-friendly practices are common.

BFHI accreditation per se does not improve breastfeeding rates at 1 and 4 months when breastfeeding-initiation rates are high and accredited and nonaccredited hospitals have infant-friendly practices. Baby-friendly practices are more important than accreditation. (Read the full article)

Children with chronic illnesses are at risk for emotional and behavioral problems. Therefore, interventions that focus on coping with the negative consequences of the disease are needed. Evidence-based interventions are limited and often focus on a single diagnosis group.

This study demonstrates the efficacy of a cognitive-behavioral group intervention for children with various chronic illnesses. The findings indicate that the involvement of parents is important to achieve long-term results. (Read the full article)

Diuretics are used in preterm infants to treat the symptoms of bronchopulmonary dysplasia (BPD), although there is little evidence of their effectiveness in improving long-term outcomes. Prescribing patterns and frequency of diuretic use in patients with BPD are unknown.

The use of diuretics in infants with BPD, including the specific medications used and length of treatment, varies widely by institution. Long-term diuretic administration to patients with BPD is commonly practiced despite minimal evidence regarding effectiveness and safety. (Read the full article)

College students with asthma tend to have worse health outcomes than their peers without asthma. Consistent use of controller medication could improve outcomes for these students, but a predictive model of appropriate use of controller medication is needed.

This study adds risk tolerance and time preference to previously studied factors of nonadherence with control medication. These preferences have substantial impacts on use of controller medication and the potential success of asthma education programs. (Read the full article)

The reasons why teens are not immunized are related to parental lack of knowledge and the need for provider recommendations.

The reasons for vaccine refusal for human papillomavirus vaccine differ from other teen vaccines, and concerns about its safety are increasing over time. (Read the full article)

Although a growing body of literature suggests links between parental incarceration and negative child outcomes, research that uses representative US samples and focuses on health outcomes is limited.

Using a nationally representative US sample, we examined the association between parental incarceration and young adult mental and physical health outcomes. Results suggest childhood exposure to parental incarceration is associated with increased risk of long-term health problems. (Read the full article)

Although it is known that extremely preterm children are at increased risk for cognitive deficits, academic underachievement, and behavioral problems, the frequency and severity of these impairments may decline with advances in neonatal care.

Despite recent changes in obstetric and neonatal management of extremely preterm infants, the rate of neurobehavioral impairments at school age is still too high. (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)

Pacifiers may interfere with breastfeeding and thus are discouraged until 3 to 4 weeks of life, when they are recommended for sudden infant death syndrome risk reduction. Hospitals are restricting pacifier distribution as part of the Baby-Friendly Hospital Initiative.

We describe a temporal association between reduced exclusive breastfeeding and pacifier restriction. This observation encourages research on breastfeeding promotion and the effects of pacifiers and pacifier restriction on breastfeeding. (Read the full article)

Racial disparities in health care have been reported in multiple settings, but not thoroughly examined at the clinician level. The frequent occurrence of respiratory tract infections allows the evaluation of differences in the management of children seen by the same clinician.

Racial differences in the management of common pediatric infections occur among children treated by the same clinician. Given persistent concerns about nonjudicious antibiotic use, examining racial differences may inform our understanding of prescribing practices and identify opportunities for intervention.

Head circumference (HC) at birth reflects brain development in utero. However, HC charts used in Canada are either dated, mixed-gender, nonrepresentative of lower gestational ages, or reflective of other populations in the world.

We developed recent and gender-specific reference curves for HC at birth for singletons of 23 to 41 completed weeks’ gestational age, which included a large number of very prematurely born infants, reflecting the current geotemporal Canadian population and advances in obstetric care.

In the era of widespread conjugate vaccine use, the prevalence of bacterial meningitis has declined. However, the impact of this decline on the rate of emergency department visits for viral meningitis and cost of caring for these children is unknown.

There was a decline in the rate of diagnosis of viral meningitis in US children’s hospitals between 2005 and 2011. Most children diagnosed with viral meningitis are treated with antibiotics and are hospitalized, accounting for considerable health care costs. (Read the full article)

Konzo is an irreversible sudden-onset upper-motor neuron disorder affecting children dependent on bitter cassava for food. The neuroepidemiology of konzo is well characterized. Children subsisting on poorly processed bitter cassava without adequate dietary sulfur-based amino acids are especially at risk.

We found a pervasive subclinical neurocognitive effect in children with konzo. This study provides the first evidence we are aware of that a motor proficiency examination can effectively characterize konzo severity. (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)

Universal hepatitis B virus (HBV) vaccination is a cost-effective strategy to control HBV infection. Giving hepatitis B immunoglobulin to neonates of HBV carrier mothers additionally reduces transmission but is not widely used because of its expense and infrastructure requirements.

Maternal screening for hepatitis B surface antigen and hepatitis B immunoglobulin treatment of neonates of hepatitis B virus carrier mothers could be a cost-effective addition to universal vaccination in settings in which health infrastructure can support such an intervention.

Adherence to infant feeding recommendations in the United States is low. The prevalence of early introduction of solid foods (<4 months of age) in the United States has been estimated to range from 19% to 29%.

Mothers’ most commonly cited reasons for early solid food introduction include perception of readiness, hunger, wanting to feed something in addition to breast milk or formula, perception of interest in solids, advice from a clinician, and to improve infant’s sleep. (Read the full article)

Excess tissue oxygenation should be avoided during neonatal resuscitation, especially in premature infants. Delivered oxygen concentrations when using a self-inflating bag (SIB) at oxygen flows <1 L/min remain to be established.

Low oxygen concentrations (30%– 40%) can be delivered with a SIB at an oxygen flow <1 L/min. A practical scheme has been developed correlating the oxygen flow rate and the corresponding delivered fraction of oxygen when using a neonatal SIB. (Read the full article)
