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

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

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)

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

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

One study examined the incidence of obesity among low-income children aged <5 years who participated in federally funded child health and nutrition programs during 1985–1990. The study examined the variations by baseline age but not by gender or race/ethnicity.

This study provides most recent data on incidence and reversing of obesity and variations across gender, baseline age, and racial/ethnic subgroups among young low-income children. We conducted multivariable analyses to examine the relative risk of obesity in population subgroups. (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)

The demand for donor kidneys for transplantation exceeds supply. En bloc kidney transplantation and donation after determination of circulatory death from pediatric donors increases the potential donor pool.

Newborn infants undergoing elective withdrawal of life support in the NICU are a previously unrecognized source of potential kidney donors. (Read the full article)

Studies assessing the accuracy of brief screening tools for postpartum depression have been conducted among adult women; however, no similar validation studies have been conducted among adolescent mothers. Accurate and valid brief depression screening tools are needed for adolescent mothers.

We found that the 10-item Edinburgh Postnatal Depression Scale (EPDS) and 2 subscales, the EPDS-7 and EPDS-2, are highly accurate at identifying postpartum depression among adolescent mothers. In pediatric settings with limited time and resources, these brief scales have potential to be used as effective depression screening tools. (Read the full article)

Warnings of increased risk for suicidality have been placed on antidepressant medications. Because antidepressants differ in their characteristics, including effects on neurotransmitters, it is possible that the risk of suicidal behavior for individual medications may differ.

In a cohort of 36 842 children with review of medical records for confirmation of suicide attempts, we found no difference for risk of suicide attempts among individual medications compared with fluoxetine, the currently recommended antidepressant for treatment of depression.

The incidence of invasive candidiasis in hospitalized infants is related to postnatal exposures, but large-scale studies relating the incidence of invasive candidiasis to changes in exposures over time are not available.

This study describes the association between the incidence of invasive candidiasis and changes in use of antifungal prophylaxis, empirical antifungal therapy, and broad-spectrum antibacterial antibiotics over time. (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)

The Centers for Disease Control and FITNESSGRAM BMI percentile thresholds are commonly used for obesity screening in youth. It is assumed that these thresholds are predictive of metabolic health risk, but little diagnostic data are available.

Both thresholds are predictive of metabolic syndrome, more so for boys than for girls, although with differing sensitivity and specificity. The diagnostic details of the thresholds can inform clinicians and practitioners about how these standards perform in practice. (Read the full article)

Congenital cytomegalovirus (CMV) infection is a leading cause of sensorineural hearing loss and neurodevelopmental impairment in full-term infants. The incidence of congenital CMV infection in preterm infants and the possible associations with developmental outcomes are unknown.

This study defines the incidence of congenital CMV infection in very low birth weight infants and identifies strong associations of congenital CMV infection with hearing loss and adverse neurodevelopmental outcomes in this population. (Read the full article)

More than 60% of all US tuberculosis cases occur among foreign-born persons, but ~90% of cases in young children occur among US-born; many of these children have foreign-born parents, suggesting that this is an important population for prevention.

This is the first study to calculate tuberculosis rates in US-born children by parental nativity. Compared with US-born children with US-born parents, rates were 32 times higher in foreign-born children and 6 times higher in US-born children with foreign-born parents. (Read the full article)

There are misconceptions regarding childhood phimosis. Textbooks still teach that male children should have retractable foreskin by age 3. Young children are referred for evaluation for phimosis, which is a commonly used diagnosis for postneonatal circumcision.

We found a high prevalence of physiologic phimosis in kindergarten children, up to 44% at age 6. We also reviewed the incidence of other congenital abnormalities in this coastal Chinese city. The management and complications of these conditions were analyzed. (Read the full article)

The incidence of Kawasaki disease is increasing in many countries. The only reported Australian incidence (3.4/100 000 <5 years) is almost 20 years old and the current Australian epidemiology and outcomes are unknown.

We analyzed 30 years’ total population hospitalization data from Western Australia. Kawasaki disease incidence increased markedly from 1979 to 2009 and is currently 9.34/100 000 <5 years. The epidemiology and cardiovascular outcomes are similar to other predominantly European-Caucasian populations. (Read the full article)

Guidelines recommend that primary care physicians provide preventive dental services to young children. Most state Medicaid programs reimburse physicians for providing fluoride varnish. Individual-level studies show that these services are effective in reducing caries-related treatments and costs.

Preventive dental services provided through a North Carolina Medicaid preventive dental program led to a reduction in dental caries among young children statewide. Programs targeting vulnerable populations through medical offices can reduce disparities in oral health among preschool-aged populations. (Read the full article)

Rapid and reliable tools for the diagnosis of neonatal sepsis are still unavailable. No single biomarker studied has yielded conclusive results. Genome-wide expression profiles (GWEPs) have been successfully determined for the diagnosis of sepsis in pediatric and adult populations.

GWEPs are described for the first time in very low birth weight infants with proven bacterial sepsis. Our results suggest that GWEPs could be used for early discrimination of septic newborn versus nonseptic infants. (Read the full article)

Chorioamnionitis (CAM) is a major risk factor for early-onset neonatal sepsis. The Committee on the Fetus and Newborn recommends extending the duration of antimicrobial therapy in neonates exposed to CAM and intrapartum antibiotics if laboratory data are abnormal, even if culture results are sterile.

When managed by using a strategy similar to recent Committee on the Fetus and Newborn guidelines, a large number of term and late-preterm infants exposed to CAM who had sterile blood culture findings were treated with prolonged antibiotic therapy, subjected to additional invasive procedures, and had prolonged hospitalization.

Varicella vaccine is effective, but there is concern that widespread use in young children may lead to a shift in the age of infection, with potentially more severe disease later in childhood and adolescence.

This study documents that varicella vaccine resulted in a decline of varicella incidence and hospitalization in all age groups, with no shift to older age groups. (Read the full article)

Homicide is the third leading cause of mortality in general population youth aged 15 to 29 years. Groups at greatest risk for early violent death (racial/ethnic minorities, males, poor persons, and urban youth) are overrepresented in the juvenile justice system.

We examined rates of and risk factors for firearm homicide and other causes of death in delinquents 16 years after detention. Our study analyzes gender differences; compares Hispanics, African Americans, and non-Hispanic whites; and includes a representative sample of delinquents. (Read the full article)

Rates of performing skeletal survey (SS) for young children presenting with fractures and at risk for abuse vary substantially across providers, with disparities associated with patients’ characteristics. Lack of consensus regarding indications for SS also contributes to this variation.

The results of this study provide a set of explicit consensus guidelines, based on the literature and on the knowledge of experts from several medical specialties, for identifying children with fractures who should undergo an initial SS. (Read the full article)

Previous research has demonstrated that family presence alongside hospitalized patients is associated with improvements in physiologic responses, reductions in anxiety, and expedited recovery. Recently, videoconferencing has been increasingly used for virtual visits to pediatric patients and their parents during hospitalization.

Our study demonstrates that in some cases, the use of videoconferencing by children and their parents for virtual visits is associated with greater reductions in stress during hospitalization compared with children and parents who do not use videoconferencing. (Read the full article)

The role of inhaled nitric oxide (INO) in the treatment of newborns with congenital diaphragmatic hernia (CDH) is poorly defined and not rigorously proven. Contemporary rates of INO use for CDH have not been reported.

INO use in neonates with CDH is widespread, and has increased in many US tertiary pediatric hospitals without associated decrease in extracorporeal membrane oxygenation use or mortality. (Read the full article)

Total serum bilirubin levels ≥30 mg/dL have been labeled as "hazardous." Levels this high are rare, occurring in 3 to 10 per 100 000 births. Few studies have examined etiologies and long-term outcomes in these infants.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a major identifiable cause, but is under-assessed. Chronic, bilirubin-induced neurotoxicity is rare and only occurred in the setting of additional risk factors (prematurity, G6PD deficiency, sepsis) and at levels far above recommended exchange transfusion thresholds.

Children born very preterm (VPT) are at high risk of educational delay. School readiness has been identified as a potentially useful clinical framework for early detection of those at greatest risk. However, evidence to support its predictive validity is limited.

VPT preschoolers are at risk of impairment across the 5 American Academy of Pediatrics school readiness domains. The number of domains affected predicted likelihood of later learning problems, supporting the utility of schoolreadiness frameworks for identifying children needing surveillance and/or support.

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)

It is thought that vaccination coverage increases during and immediately after an infectious disease epidemic; however, little evidence exists to support this phenomenon.

The 2011 to 2012 pertussis epidemic did not significantly change the proportion of infants in Washington State who were up to date for pertussis-containing vaccines. This finding may challenge conventional wisdom that vaccine acceptance uniformly increases when risk of disease is high. (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)

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)

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)

Germ cell tumors in children are heterogeneous and rare neoplasms that occur in various locations, such as gonads, the central nervous system, and the pelvis. The incidence rate has been increasing in some countries.

Population-based analyses of germ cell tumors in children are rare. This population-based study describes the incidence rates, trends, and survival of germ cell tumors in German children from 1987 to 2011. (Read the full article)

Frequency of influenza vaccination is low, partially because of missed opportunities to vaccinate. Barriers to implementing successful influenza vaccination reminders in the electronic health record include alert fatigue and incomplete vaccination information due to scattered records.

A noninterruptive, immunization information system–linked influenza vaccination reminder can increase vaccination late in the winter when fewer vaccine doses are usually administered. Tailoring the reminder to clinicians’ needs can increase its use. (Read the full article)

Behavioral observations influence a clinician’s decision to diagnose or refer, and may even override formal screening results. In the case of autism spectrum disorder, an expected rate of atypical behavior during the span of a medical visit is unknown.

We are the first to quantify the high base rates of typical behavior in young children who have autism and language delay. When observation times are brief, the preponderance of typical behaviors may negatively impact referral decision accuracy. (Read the full article)

Uptake of rotavirus vaccines has increased steadily since introduction. Despite their demonstrated impact, rotavirus vaccine coverage is lower than for other vaccines recommended in infancy and disease continues to occur.

We observed higher rotavirus detection rates among patients from provider locations with lower rotavirus vaccine coverage; providers who do not offer rotavirus vaccine to age-eligible children may create pockets of susceptible children that serve as reservoirs of ongoing disease transmission.

Meningococcal disease is a serious but rare infectious disease. In 2012, the incidence of meningococcal disease was at a historic low in the United States; however, incidence remained highest among infants aged <1 year.

This report describes the epidemiology and burden of meningococcal disease in infants aged <1 year in the United States and potential risk factors for transmission to this vulnerable group. These data are key to informing future meningococcal disease vaccination strategies. (Read the full article)

Bruising is common in young victims of physical abuse as well as in cases of accidental trauma. There is uncertainty regarding which young children with bruising require evaluation with skeletal survey for possible abuse.

The results of this study provide guidelines, based on the literature and knowledge of experts, for identifying children <24 months presenting for care in the hospital setting with bruises, who should and should not undergo skeletal survey. (Read the full article)

Asthma is heterogeneous and 40% to 70% of patients fail to achieve control with current treatment strategies. To delineate relevant subphenotypes of asthma, identify key factors, and test novel interventions, comprehensive repositories linking clinical, environmental, and biologic data are required.

This is the first statewide repository for inpatient pediatric asthma. The data collected will better define asthma phenotypes, identify care practices associated with the best health outcomes, and inform personalized care plans to reduce reutilization and readmission for pediatric asthma.

This is the first population-based study regarding the epidemiologic characteristics of pediatric zoster among only those who had contracted varicella.

The herpes zoster (HZ) incidence among only children with varicella infection is higher than previously reported. The HZ incidence increased for children contracting varicella aged <2 years. After a vaccination program, the HZ risk increased for those contracting varicella aged ≥2 years. (Read the full article)

Off-label prescription of inhaled nitric oxide (iNO) to neonates <34 weeks’ gestation has increased during the past decade. In early 2011, the National Institutes of Health determined that the available evidence did not support iNO use in this population.

Use of iNO among neonates <34 weeks’ gestation has increased since 2011, entirely from greater use in extremely preterm neonates. Off-label prescription of this drug now accounts for nearly half of all iNO use in American NICUs. (Read the full article)

Asthma is one of the most common chronic diseases in children. It has been suggested that maternal depression during pregnancy is associated with asthma in the offspring, but the role of antidepressant use during pregnancy is not known.

In our prospective cohort study, we found that maternal antidepressant use during pregnancy generally did not increase the risk of asthma except for use of older antidepressants, which could reflect confounding by the severity of maternal depression. (Read the full article)

Blood cultures are the most widely available diagnostic tool to identify bacterial pathogens in community-acquired pneumonia (CAP). Despite a recent national guideline recommendation for blood culture performance in children with moderate/severe CAP, there is still wide variation across institutions.

Using improvement methodology, we demonstrated that blood cultures can be routinely performed in children admitted for CAP, in accordance with a recent national guideline, without increasing length of stay in a setting with a low false-positive blood culture rate. (Read the full article)

Existing literature discusses the unique medical and psychological needs of sex trafficking victims and highlights the importance of screening patients with risk factors. However, little is known about providers’ knowledge and confidence in their ability to provide care to victims.

The study summarizes the knowledge gaps and barriers providers face when assisting pediatric sex trafficking victims. It also highlights the impact of training on providers’ confidence and ability to appropriately care for victims. (Read the full article)

Although opioid pain relievers are commonly prescribed in pregnancy, their association with neonatal outcomes is not well described. Further, factors associated with development of neonatal abstinence syndrome, a neonatal opioid withdrawal syndrome is inadequately understood.

Prescription opioid use in pregnancy is common and strongly associated with neonatal complications. Antenatal cumulative prescription opioid exposure, opioid type, tobacco use, and selective serotonin reuptake inhibitor use increase the risk of neonatal abstinence syndrome. (Read the full article)

Neonatal arterial ischemic stroke is associated with later cerebral palsy and cognitive impairment. Many studies on neonatal ischemic stroke are limited by modest sample sizes, and prospective studies that include outcomes assessments are scarce.

Results from this prospective, nationwide, population-based study provide information on the epidemiology, associated clinical variables, clinical manifestation, vascular distribution, and treatment of neonatal arterial ischemic stroke. The study also provides outcomes regarding motor function and cognition. (Read the full article)

Although waning immunity with the childhood pertussis vaccination series has been reported, there are limited data on duration of protection of the adolescent pertussis vaccine (Tdap), especially among those who have received only acellular vaccines.

This study reports that protection from Tdap wanes substantially 2 to 4 years after vaccination among adolescents who received all acellular vaccines during childhood. This waning protection is likely contributing to the increase in adolescent pertussis. (Read the full article)

More than a quarter of child deaths in the United Kingdom are estimated to have identifiable failures in care. Although children account for 40% of the family practice workload, little is known about iatrogenic harm to children in this setting.

This is the first analysis of nationally collected pediatric safety incident reports from family practice. To mitigate harm to children, priority areas requiring improvement include medication provision, referral of unwell children, provision of evidence-based treatment, and adequate diagnosis and assessment.

Various clinical and demographic factors are associated with sudden infant death syndrome (SIDS), and an association between altitude of residence and SIDS has been questioned but not yet demonstrated in any large observational studies.

This study demonstrates an association between altitude and SIDS, with higher SIDS rates observed at high elevation (>8000 feet) than at the more moderate elevations (<6000 feet). (Read the full article)

Tonsillectomy guidelines make evidence-based recommendations for the perioperative use of dexamethasone, no routine use of antibiotics, and discharge education of families and for surgeons to monitor bleeding complication rates. The impact of the guidelines on processes and outcomes is unknown.

The guidelines were associated with improvement in perioperative care processes but no improvement in outcomes. Perioperative dexamethasone use increased slightly, and antibiotic use decreased substantially. Bleeding rates were stable, but revisit rates for complications increased because of revisits for pain.

The 2011 national guidelines for the management of pediatric community-acquired pneumonia recommended narrow-spectrum antibiotic therapy (eg, ampicillin) for most children hospitalized with pneumonia. Before the release of the guidelines, the use of broader-spectrum antibiotics (eg, third-generation cephalosporins) was much more common.

After release of the guidelines, third-generation cephalosporin use declined and penicillin/ampicillin use increased among children hospitalized with pneumonia. Changes were most apparent among institutions that proactively disseminated the guidelines, underscoring the importance of local efforts for timely guideline implementation. (Read the full article)

Medicaid made substantial investments in enhanced prenatal and postnatal care programs to address maternal and infant health, including infant mortality. Evaluations of population-based programs are few, and although some have reported reductions in infant mortality, they have methodological limitations.

A population-based home visitation program can be a successful approach to reduce infant mortality. The reduced risk of infant death is consistent with previous findings on the effects of the program on health care utilization and birth outcomes. (Read the full article)
