Trisomy 13 and 18 are conditions with 1-year survival rates of less than 10% and have traditionally been treated with palliative care. There are increasing reports of ethical dilemmas caused by parental requests for clinical interventions.

Parents who belong to social networks report an enriching family experience and describe surviving children as happy. Many of these parents describe challenging encounters with health care providers. (Read the full article)

Because most childhood tuberculosis cases are sputum smear-negative, diagnosis relies largely upon clinical presentation, tuberculin skin testing, and chest radiograph. Diagnostic limitations contribute to treatment delays and high mortality. However, childhood tuberculosis (TB) mortality risk factors are not well documented.

This study demonstrates that false-negative TST is common in children with active TB and is associated with increased risk of death. A negative TST should not delay anti-TB therapy. Improved diagnostic modalities are urgently needed in resource-limited settings. (Read the full article)

Food insecurity has been linked to childhood obesity in a number of studies. Few studies have explored potential pathways through which food insecurity is related to child weight, especially in low-income families with young infants.

We found that food insecurity was related to maternal controlling feeding styles and concerns about the infants’ future weight. Early obesity prevention should aim to decrease food insecurity and to reduce controlling feeding styles in families who remain food insecure. (Read the full article)

Children with obstructive sleep apnea (OSA) are usually treated by surgical removal of their upper airway lymphadenoid tissue. Recently, medications were offered to patients with nonsevere OSA. Montelukast, for this indication, had never been studied in a randomized controlled manner.

Montelukast effectively reduced polysomnographic findings, symptoms, and the size of the adenoidal tissue in children with nonsevere OSA. The findings support the potential of a leukotriene modifier as a novel, safe, noninvasive alternative for children with mild to moderate OSA. (Read the full article)

Honey is recommended as a cough medication by the World Health Organization. To date, the efficacy of this treatment has been shown in 2 studies: one tested only buckwheat honey and the other study was not blinded.

In a randomized controlled trial, we compared 3 types of honey versus placebo as a treatment of upper respiratory tract infection–associated cough. These types of honey were superior to placebo in alleviating cough. (Read the full article)

Bronchiolitis is one of the most common infectious respiratory conditions of early childhood, and most children have a mild clinical course. Unfortunately, the small subgroup of children requiring continuous positive airway pressure and/or intubation remains ill-defined.

In children with bronchiolitis, we found several demographic, historical, and clinical factors that predicted the need for mechanical respiratory support including in utero smoke exposure. We also found a novel subgroup of children with bronchiolitis who have a rapid respiratory decline. (Read the full article)

Ideal empirical antibiotic choices are based on local susceptibility data. These choices are important for ensuring positive patient outcomes, but pediatric-specific data may not be available.

Antibiotic susceptibilities differ by age group within a tertiary-care hospital. Knowing these differences, pediatricians chose empirical antibiotic therapy more likely to be successful. Children with infectious diseases would benefit from reporting of pediatric-specific susceptibility results. (Read the full article)

Cholestasis predisposes to the development of fat-soluble vitamin (FSV) deficiency. D-α tocopheryl polyethylene glycol-1000 succinate and coadministered FSVs are absorbed in spite of cholestasis.

Infants with biliary atresia with total bilirubin >2 mg/dL are at risk for fat-soluble vitamin (FSV) deficiency. A multivitamin preparation containing d-α tocopheryl polyethylene glycol-1000 succinate alone is not effective in treating biochemical FSV insufficiency in cholestatic infants.

There is evidence from both developed and developing countries that antiretroviral treatment significantly reduces mortality in HIV-infected children. However, in sub-Saharan Africa, numerous health system, financial, and human resource obstacles make delivering quality pediatric HIV care a challenge.

We describe the experience of the Baylor International Pediatrics AIDS Initiative in Malawi, Lesotho, and Swaziland. Despite challenges delivering pediatric treatment in these countries, mortality and clinical outcomes approaching those from developed countries are feasible. (Read the full article)

Materialism and life satisfaction are known to be associated with each other. Research among adults has shown that materialism and life satisfaction negatively affect each other, leading to a downward spiral.

In contrast to research conducted among adults, no longitudinal effect of materialism on life satisfaction was found for 8- to 11-year-olds. However, life satisfaction did negatively affect materialism, but only for children who were frequently exposed to advertising. (Read the full article)

Birth defects are associated with preterm birth and are a major contributor to infant mortality. There are persistent black-white differences in overall infant mortality and infant mortality attributable to birth defects.

Among infants delivered at 37 to 44 weeks, blacks and Hispanics had significantly higher neonatal and postneonatal mortality attributable to birth defects than whites. Among infants delivered at 20 to 33 or 34 to 36 weeks, neonatal mortality attributable to birth defects was significantly lower among blacks. (Read the full article)

The importance of and interest in childhood mental problems have increased worldwide. There are few population studies on child and adolescent mental health and health-related quality of life (HRQoL).

A social gradient was found in childhood mental health according to maternal education level and social class, but none was found in HRQoL, although children from disadvantaged social classes had somewhat lower HRQoL scores than their more advantaged counterparts. (Read the full article)

Asthma is a major reason for pediatric hospital admission. The Joint Commission requires freestanding children’s hospitals to report compliance with 3 Children’s Asthma Care quality measures. High compliance with these measures should result in decreased admissions and emergency department visits.

Implementation of a standardized care process model for hospitalized asthmatic children resulted in high compliance with all 3 measures. Measures 1 and 2 did not provide an opportunity for improvement. Compliance with measure 3 resulted in significant decreases in readmission. (Read the full article)

A growing number of epidemiologic studies suggest that individuals with lower vitamin D levels are at higher risk of acute respiratory tract infection. Randomized controlled trials are needed to determine if vitamin D supplementation would decrease this risk.

In a randomized controlled trial of 247 Mongolian children with vitamin D deficiency in winter, with double-blinding and 99% follow-up, vitamin D supplementation significantly reduced the risk of acute respiratory tract infections. (Read the full article)

The higher the predischarge bilirubin percentile reading on the hour of life–specific nomogram, the higher becomes that infant's risk of developing significant hyperbilirubinemia. Neonates in the low-risk zones (≤75th percentile) have a low risk of developing hyperbilirubinemia.

Thirty-two percent of newborns readmitted for hyperbilirubinemia had low-risk zone predischarge bilirubin percentile values, predominantly in the intermediate low-risk zone (41st–75th percentile). The intermediate low-risk zone may not be as low risk as previously thought. (Read the full article)

Evaluation of neonatal surgical outcomes is necessary to guide improvements in the quality of care. Meaningful comparisons must adjust for factors that alter outcomes independent of the surgical procedures.

Herein is described a method that permits risk adjustment for the broad range of noncardiac neonatal surgery, regardless of gestational age, to permit useful comparisons for quality improvement. (Read the full article)

Although several studies have demonstrated increased morbidity and mortality with pH1N1 in children, others have found its clinical course to be similar to seasonal influenza. Moreover, most studies were conducted at single centers, thus raising concerns about generalizability of findings.

This analysis provides national-level active hospital-based surveillance data comparing pH1N1 with 5 previous years of seasonal influenza A and demonstrates differences in risk factors and clinical presentation but not in ICU admission or mortality. (Read the full article)

Despite the dramatic rise in prevalence of metabolic syndrome (MetS) among children and adolescents, and that MetS is associated with cognitive and brain impairments among adults, no data on the impact of MetS on the brain exist in children.

It provides the first data on the impact of MetS on brain in adolescence. We show reductions in cognitive function and brain structural integrity in nondiabetic adolescents with MetS, thus suggesting that even pre-clinical metabolic illness may give rise to brain complications.

There are no studies to support the clinical awareness of persistent Tanner stage (TS) 4 breast development in adulthood, and forensic experts continue to use TS 4 as evidence of age <18 years in cases of alleged child pornography.

One-fourth of nonclinical images of women over 18 years of age could be considered by a single forensic expert to represent TS 4. This observation, and substantial discordance in interpretation by pediatric endocrinologists, renders testimony based on this distinction invalid. (Read the full article)

Childhood obesity is a public health concern. Although determinants of childhood overweight have been identified and their effect sizes have been calculated, prevention as well as treatment have had limited success.

We have calculated the population-based relevance of determinants of childhood overweight by using attributable risks, which can be interpreted as maximum success rates of preventive measures. New concepts were applied to estimate the relative contribution of each risk factor. (Read the full article)

Rotavirus is a major cause of acute gastroenteritis among children worldwide. Vaccines targeting rotavirus have been demonstrated to be highly efficacious against severe disease in clinical trials and postlicensure studies. Vaccine impact on mild gastroenteritis has not been well studied.

We used a novel surveillance platform consisting of telephone triage data to capture mild gastroenteritis not detected in other surveillance systems. Since rotavirus vaccine licensure, gastroenteritis-related call proportions have declined, and peak gastroenteritis-related calls are correlated with community norovirus circulation.

Critics argue that pediatric research without the potential for clinical benefit treats children as mere means to benefit others. Yet, there are no data to assess whether adolescents who participate in research, or their parents, agree with this view.

Respondents felt that by participating in research the adolescents were making important contributions to help others, and the adolescents felt proud to be doing so. These findings support the view that nonbeneficial pediatric research involves a type of charitable activity. (Read the full article)

Although the natural course of bilirubin levels has been extensively studied in general neonatal populations, there is a paucity of data regarding bilirubin trends in neonates before the development of significant hyperbilirubinemia.

This study provides data on the natural course of transcutaneous bilirubin before the development of significant hyperbilirubinemia, and on the effect of different demographic and perinatal risk factors on the rate of bilirubin increase in neonates with borderline bilirubin values. (Read the full article)

Severe neonatal hyperbilirubinemia can lead to acute bilirubin encephalopathy and, subsequently, chronic bilirubin encephalopathy (CBE). This condition is preventable through routine identification and proper treatment; therefore, it is rare for permanent neurologic complications to occur.

This article describes the incidence of CBE in Canada, which is higher than previously reported in the literature. Furthermore, it describes the underlying causes of CBE and the spectrum of neurologic disease. (Read the full article)

Mortality of very low birth weight infants varies widely between regions and countries; however, the variation in morbidities after adjusting for confounders has not been adequately studied.

Composite outcome of mortality or short-term morbidity for very low birth weight infants was lower in Japan than in Canada. However, marked variations in mortality and individual morbidity exist, revealing areas for improvement in each country. (Read the full article)

Fever phobia is a ubiquitous problem throughout the world. As a result, fever is pharmacologically overtreated, and medical attention is frequently sought by worried parents.

Most Canadian parents fear their child’s fever, resulting in aggressive surveillance and treatment. Parents expect information about fever etiology and how to care for their ill child. Few parents expect antibiotics and satisfaction with care is high. (Read the full article)

Sending and receiving sexually explicit picture and text messages via cell phone (ie, "sexting") among adolescents is publicized as a societal and public health concern, yet it is unknown whether sexting is associated with physical sexual activity or sexual risk behavior.

This study is the first to examine sexting among a probability sample of adolescents and found that sexting is associated with sexual activity, sexual risk behavior, and knowing other person(s) who have sent a sext. (Read the full article)

Pediatric obesity is a prevalent public health issue that is associated with medical and physical consequences. Clinic-based interventions for pediatric obesity are effective, but they have limited reach and are costly.

This is the first examination of an empirically informed, scalable treatment of pediatric overweight and obesity delivered in YMCAs. The results indicate that a scalable, community-based pediatric obesity intervention can produce clinically meaningful changes in weight and quality of life. (Read the full article)

Findings from 3 studies suggest that the diagnosis of venous thromboembolism in hospitalized US children has increased in recent years.

This study provides additional evidence of an increasing trend in the rate of venous thromboembolism-associated hospitalization in US children, as well as a concurrent increase in the prevalence of venous catheter procedures. (Read the full article)

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)

Most studies on corticoid treatment of respiratory syncytial virus (RSV) respiratory diseases have revealed no beneficial effect. The mechanism by which RSV respiratory-infected patients are insensitive to the antiinflammatory effect of corticosteroids is unknown.

This study helps to understand how a respiratory syncytial viral infection may alter the normal antiinflammatory response to cortisol and the insensitivity to glucocorticoid treatment. The increase expression of β glucocorticoid receptor could be a marker of disease severity. (Read the full article)

There are limited data regarding the current status of the pediatric clinical trial enterprise.

Evaluation of the ClinicalTrials.gov data set allows description of the overall portfolio of clinical trials relevant to US children, which was previously not possible. (Read the full article)

Discussing end-of-life (EoL) care with adolescents and young adults (AYAs) is difficult. Often, such conversations are delayed or avoided, but AYAs contemplate EoL issues and want to make decisions about their care. Few established resources exist to help this process.

Results support the use of a developmentally appropriate document that allows AYAs an opportunity to share their choices about EoL care and how they would like to be remembered in the future. (Read the full article)

Retinal hemorrhages occur in accidental and inflicted traumatic brain injury (ITBI) and some medical encephalopathies. Large numbers and peripherally located retinal hemorrhages are frequently cited as distinguishing features of ITBI in infants, but the predictive value has not been established.

This prospective retinal imaging study found that a diagnosis of ITBI in infants and children can be distinguished from other traumatic and nontraumatic causes by the presence of >25 dot-blot (intraretinal layer) hemorrhages (positive predictive value = 93%). (Read the full article)

Chromosomal microarray analysis offers a superior diagnostic yield over karyotyping for the evaluation of individuals with developmental disabilities. Many third-party payers, however, do not reimburse for microarray testing, citing a lack of evidence that patients benefit from testing.

This study demonstrates that microarray testing frequently identifies conditions that include features requiring specific medical follow-up and that referring physicians respond to abnormal test results with appropriate clinical actions. Microarray testing, therefore, provides direct benefits to patients. (Read the full article)

Healthy sleep is essential for supporting alertness and other key functional domains required for academic success. Research involving the impact of modest changes in sleep duration on children’s day-to-day behavior in school is limited.

This study shows that modest changes in sleep duration have significant impact on the behavior of typically developing children in school. Modest sleep extension resulted in detectable improvement in behavior, whereas modest sleep restriction had the opposite effect. (Read the full article)

Chronic nonbacterial osteomyelitis (CNO) is a sterile inflammatory bone disorder of presumed autoimmune or autoinflammatory etiology predominantly affecting children. There are limited data on the characteristics and optimal treatment of CNO in the United States.

A US-based cohort of pediatric CNO patients revealed high rates of personal and familial autoimmunity. Coexisting autoimmunity was a risk factor for widespread involvement. Response to nonsteroidal antiinflammatory drugs was inferior to that with immunosuppressive and biologic agents. (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)

Patients living in rural versus urban counties encounter different health care environments. Whether these differences result in different health care utilization for rural versus urban infants is not known.

In this study, infants living in rural California counties were hospitalized less often than infants living in urban counties. Among those hospitalized, infants living in rural counties were hospitalized for fewer cumulative days than infants residing in urban counties. (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.

Medical advances have prolonged life for children and adolescents with Duchenne muscular dystrophy (DMD), the most common inherited pediatric neuromuscular disorder. Children with this progressive disease surviving to adulthood still face significant threats to their quality of life.

Self-reported psychosocial quality of life was impaired in a significant number (57%) of boys with DMD, unrelated to their need for mobility aids. Concordance between the perceptions of parents and their sons related to psychosocial functioning was fair to poor. (Read the full article)

The past several decades have seen a dramatic increase in the costs of health care and the prevalence of childhood activity limitations. More families with children are experiencing financial burden related to the cost of health care and insurance.

We find significant inequities in the occurrence of delayed or forgone needed health care for families with children as a result of high health care–related financial burden and having a child with an activity limitation. (Read the full article)

Previous studies have demonstrated that booster seat legislation decreased fatalities in children. However, these studies have not accounted for confounding factors such as other legislation and temporal trends in safety.

This study demonstrates that state booster seat laws are associated with decreased rates of fatalities and injuries in children 4 to 7 years of age in the United States, with the strongest effects in the older children. (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.

There is concern about the potential exploitation of children who are enrolled into clinical trials in developing and transition countries. Previous studies of globalization have only examined pediatric drug trials, and only 1 study has provided patient-level data by country.

The involvement of developing and transition countries depends on the product or indication under investigation and is greater for vaccines than for drugs or biologicals. Compared with our previous analysis, involvement of these countries in pediatric drug development has decreased. (Read the full article)

Several studies have reported inverse associations between fish consumption during pregnancy or later childhood and asthma prevalence. However, because fish can also be highly allergenic, the optimal timing of introduction of fish and the adequate amount in infancy remains unclear.

Introduction of fish between 6 and 12 months but not fish consumption afterward is associated with a lower risk of wheezing whereas no introduction of fish or introduction between 0 and 6 months of life increases the risk of wheezing. (Read the full article)

The effect of substandard housing on children’s risk of diseases such as asthma has been studied; little is known about how it affects child injury risk. Pediatricians actively promote injury prevention but typically without regard to housing quality.

Low-income children are likely living in substandard homes, which is significantly associated with not having working smoke alarms and safe hot water temperatures. Pediatricians can use these results to inform anticipatory guidance. (Read the full article)

In the United States, adolescent obesity rates have tripled in the last 3 decades, with concomitant increases in other metabolic risk factors, including the metabolic syndrome (MetSyn). However, in Asian countries, these same risks have only recently begun increasing.

Representative data for the United States and Korea reveal trends in adolescent obesity and MetSyn moving in opposite directions. This study provides a benchmark for Korea and other Asian countries toward mitigating the upward trends in obesity and MetSyn. (Read the full article)

National asthma treatment guidelines include the recommendation that all asthma patients receive a written asthma action plan. No previous study has sought to examine the readability, suitability, and content of asthma action plans within a nationally representative sample.

Although variability was found across written asthma action plans, and improvements in readability, suitability, and content are needed, there were also many common elements that would support a move to a single universal standard action plan. (Read the full article)
