Infant and neonatal mortality rates in the United States decreased markedly during the twentieth century but have not decreased notably during recent years. There has been an increase in preterm and low birth weight births in recent years.

The lack of decrease in infant and neonatal mortality rates in recent years is due in large part to the increasing proportion of preterm and low birth weight infants, particularly infants <500 g. (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)

Rates of screen media use have risen in parallel with rates of obesity among young people. Identifying the specific characteristics of media use that are associated with obesity can help elucidate the explanatory processes and inform effective interventions.

This study examines the associations between BMI and characteristics of media use including the type of device, duration of use, and attention to the medium. The more that participants paid primary attention to television, the higher their BMI. (Read the full article)

Early readmission of apparently healthy newborns may result from inadequate assessment of a newborn’s readiness for discharge. Knowledge of the frequency, causes, and variation in the rate of newborn readmissions may assist in developing quality improvement interventions.

Feeding problems and jaundice, both potentially preventable, are the leading causes of readmission. Late preterm and early term newborns are more likely to be readmitted and should have close follow-up after discharge from a well baby nursery. (Read the full article)

Active smoking and secondhand smoke are associated with chronic kidney disease in adults. No data are available for children.

Secondhand smoke and active smoking were associated with decreased estimated glomerular filtration rate in US adolescents. These findings support that tobacco smoke effects on kidney function begin in childhood. (Read the full article)

Delayed anaphylaxis, urticaria, and angioedema to mammalian meat products were first described in the adult population in 2009. Patients with this syndrome who consume mammalian meat typically develop symptoms 4 to 6 hours after ingestion.

Specific diagnoses for children who develop urticaria, angioedema, and idiopathic anaphylaxis are few and far between. We have now shown delayed anaphylaxis, urticaria, and angioedema due to mammalian meat products in the pediatric population. (Read the full article)

Some Western studies show early introduction of solid food is associated with subsequent obesity. However, introduction of solid food and obesity share social patterning, making these observations vulnerable to residual confounding.

In a non-Western developed setting, there was no clear association of the early introduction of solid food with childhood obesity. Studies in populations with a different confounding structure may be valuable in clarifying and reconciling potentially confounded epidemiologic associations. (Read the full article)

Clinically significant bleeding in pediatric immune thrombocytopenia (ITP) is rare. Evidence-based guidelines for the management of pediatric ITP recommend that patients with mild or no bleeding be followed with observation alone.

Many pediatric patients with newly diagnosed ITP continue to be managed in the inpatient setting. Bleeding events are rare in this setting. Although geographic variability exists, intravenous immunoglobulin is the most commonly used inpatient ITP treatment in the United States. (Read the full article)

Advances in the treatment of critically ill infants have increased survival of extremely low/very low birth weight and medically complex infants. Improved survival can result in prolonged mechanical ventilation and sometimes tracheostomy. Current tracheostomy rates for these infants are unknown.

This long-term review of infants discharged from a NICU with tracheostomies is the first to describe tracheostomy rates specifically in extremely low/very low birth weight infants. It focuses on long-term clinical outcomes and comorbidities rather than surgical complications. (Read the full article)

The incidence of childhood and adolescent melanoma has been significantly increasing up to 2004. Risk factors (fair skin, light-colored hair/eyes, female gender, presence of nevi, family history, increased number of sunburns, and exposure to UV radiation) are associated with melanoma.

This study describes incidence trends of melanoma diagnosed between the ages of 0 and 19 years and from 1973 through 2009 by gender, stage and age at diagnosis, primary site, and exposure to UV radiation. (Read the full article)

Recorded music, parent voices, and sung lullabies have been shown to increase oxygen saturation, nonnutritive sucking, and weight gain in premature infants.

Parent-preferred melodies and entrained live rhythm and breath sounds can enhance quiet alert and sleep states, suck response, and oxygen saturation in premature infants and significantly reduce fear and anxiety perception in parents. (Read the full article)

Previous studies have suggested that health care providers, family members, friends, and others play a role in shaping parents’ vaccination decisions. Other research has suggested that the media can influence whether parents decide to vaccinate their children.

Through the application of social network analysis, this study formally examines and quantifies how parents are influenced by the people and sources around them. Its findings suggest that social networks are important, particularly for parents who do not completely vaccinate. (Read the full article)

Oropharyngeal dysphagia (OPD) prevalence is 19-99%. OPD based on parent-report is associated with gross motor skills in children with cerebral palsy (CP), however this underestimates prevalence. Almost all children with severe CP have dysphagia; little is known about mild CP.

The prevalence of directly assessed OPD in preschool children with CP is 85% (70% in GMFCS I; 100% in GMFCS V). OPD was prevalent even in mild CP. Gross motor functional capacity is strongly related to dysphagia severity and prevalence. (Read the full article)

At least half of the achievement gap for low-income, minority children is present at kindergarten entry; however, there are no population-level early childhood interventions that effectively engage and support families and teachers to ameliorate the impact of adversity on achievement.

This study evaluated ParentCorps, a family-centered, school-based intervention to promote self-regulation and learning for all children entering school in disadvantaged, urban neighborhoods. ParentCorps results in higher kindergarten achievement among low-income, minority children. (Read the full article)

Antibiotics-induced rash in Epstein-Barr virus acute infectious mononucleosis, especially the aminopenicillins-induced type, was first described during the 1960s, with a reported incidence of 80% to 100%. This phenomenon was not further investigated but is well-established in pediatric textbooks.

The main observation of this study is that rash induced by amoxicillin in confirmed Epstein-Barr virus acute infectious mononucleosis was found at a rate of ~30%, which is much lower than previously reported. (Read the full article)

Cognitive and motor developmental test scores of preterm and late preterm infants increase with gestational age. Developmental test scores in full-term infants have not previously been considered to relate to gestational age.

In a cohort of healthy, full-term infants, 37 to 41 weeks, 12-month mental and psychomotor scores on the Bayley Scales of Infant Development increased with gestational age, suggesting that neurodevelopment is optimal in infants born at 39 to 41 weeks. (Read the full article)

Pulse oximetry testing in newborns can detect asymptomatic cases of critical congenital heart defects and has been added to the US Recommended Uniform Screening Panel. However, the impact that earlier diagnosis may have on survival in this population is unclear.

One-year survival for infants with critical congenital heart defects has been improving over time, yet mortality remains high. Survival has been greatest for those diagnosed after 1 day of age and may increase more with screening using pulse oximetry. (Read the full article)

Parents of children with chronic cough have poor quality of life and often seek multiple consultations. There are few randomized controlled trials on the management of cough or on the efficacy of management algorithms outside of inpatient settings.

In a multicenter, trial, we found that the management of children with chronic cough, in accordance with a standardized algorithm, improves clinical outcomes. Earlier application of the algorithm leads to earlier cough resolution and improved parental quality of life. (Read the full article)

Survival of children with spinal muscular atrophy type 1 is determined by treatment choice: tracheostomy with mechanical ventilation, noninvasive mechanical ventilation, or a palliative approach. Few data are available on life expectancies with different approaches.

The present study provides data comparing therapeutic strategies that affect life expectancy. Clinicians involved in the care of patients with spinal muscular atrophy type 1 should be aware of survival trends while awaiting more definitive therapeutic strategies. (Read the full article)

Studies suggest that young adults have worse access to health care, use less primary care, and visit emergency departments more frequently than adolescents. Whether these differences are present between adolescents and young adults with asthma is unknown.

Young adults with asthma were less likely to have a usual source of care and use primary care. In contrast, they were more likely to use the emergency department. Adjusting for insurance coverage reduced these differences partially but not completely. (Read the full article)

Heated, humidified high-flow nasal cannula (HHHFNC) is a noninvasive mode of respiratory support that is commonly used in the majority of US NICUs. No large randomized trial has evaluated safety or efficacy of HHHFNC.

This large randomized controlled trial suggests that HHHFNC is as effective as nCPAP for noninvasive respiratory support and can be safely applied to a wide range of neonates. (Read the full article)

Perforation in the setting of retained esophageal foreign body is rare, but can be catastrophic. The role of imaging in screening for injury after removal has not previously been studied.

The rate of esophageal injury among children with retained esophageal foreign body is 1.3%. Intraoperative findings suggestive of injury are predictive of perforation. Routine chest radiography is not warranted in those who do not meet this criterion. (Read the full article)

Current recommendations to prevent warts focus on limiting the personal spread of human papillomavirus and transmission in public places, such as swimming pools; however, evidence on risk factors for developing warts is limited.

Cutaneous human papillomavirus in primary schoolchildren is primarily transmitted in the family and school class. This suggests that recommendations should shift toward reducing transmission in families and school classes. (Read the full article)

Children are taking more medications than ever before. Medication errors in the hospital are common. Less is known about the medication errors that occur in children's homes, and there are no studies that examine the entire process.

We reviewed 963 medications in the homes of children with cancer at 3 sites. We found 3.6 errors with injury and 36 errors with potential for injury per 100 patients. Interventions should target common and dangerous errors at home. (Read the full article)

Juice consumption among 2- to 5-year-old children exceeds dietary recommendations. In 2007, the US Department of Agriculture revised the composition and quantities of prescribed foods in WIC food packages to align them with dietary guidelines. Juice allowances were reduced by approximately half.

WIC participants purchased about a quarter less juice volume after implementation of the revised WIC packages. Large reductions in WIC-provided juice were only partly compensated for by extra juice purchases with non-WIC funds. Little compensation occurred for other beverages. (Read the full article)

The Ages and Stages Questionnaires (ASQ) has been validated in many countries and translated into numerous languages. In most publications, it has been reported that the ASQ is accurate in detecting true problems in apparently healthy children and even in children with biological risk factors.

This report compares the third version of the ASQ and the Bayley Scales of Infant and Toddler Development, Third Edition, assessments. Psychometric properties showed a tendency to improve with testing age and when comparing term versus extremely preterm children. (Read the full article)

Botulinum spores are ubiquitous, found in the soil of most countries worldwide, and also in honey. It is well established that ingestion of honey by children aged <1 year can lead to infant botulism.

This study examines the prevalence of honey pacifier use among a pediatric population aged <1 year. We also assessed parental knowledge of the dangers of giving honey to children in this age group. (Read the full article)

The systemic nonselective β-blocker propranolol hydrochloride is increasingly used as first-line management for infantile hemangiomas. Superficial nonulcerating lesions do not require systemic medications. Case series have suggested the efficacy of timolol; however, its safety has been questioned.

This randomized controlled trial indicates that timolol maleate 0.5% gel is a well-tolerated, safe, and effective treatment of superficial infantile hemangiomas. (Read the full article)

Previous studies report Hispanic adults have lower access to rehabilitation services, especially among those who only speak Spanish, and higher disability after traumatic brain injury (TBI) compared with non-Hispanic white subjects. No studies have examined disparities in disability after TBI for Hispanic children.

Hispanic children experience disparities in long-term disability after TBI. Compared with non-Hispanic white children, Hispanic children report significantly larger reductions in health-related quality of life, participation in activities, and ability to communicate and care for themselves 3 years after injury.

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)

Extremely preterm infants who receive antihypotensive therapy have worse outcomes than untreated infants. The reasons for this are not clear. High-quality randomized trials have not been performed to date because of logistical challenges, thereby necessitating alternative methods of investigation.

Antihypotensive therapy administration was not associated with improved in-hospital outcomes for any of the 15 definitions of low blood pressure investigated. Alternative methods of deciding who to treat are needed to maximize patient benefit and minimize harm. (Read the full article)

Yearly influenza immunization is recommended in patients with inflammatory bowel disease (IBD). However, concern regarding vaccine-related adverse events may limit uptake, and case reports in the literature detail disease flares after immunization.

Influenza immunization rates in children with IBD are low but immunization did not result in increased outpatient visits, hospitalizations or emergency visits. Immunization was associated with fewer IBD-related visits in the post-vaccine period, which may indicate protection against IBD symptoms. (Read the full article)

Despite evidence on how malpractice risk varies according to physician specialty, there is growing but still limited evidence about malpractice among US pediatricians. The frequency of malpractice claims against pediatricians is low among specialties, but payments are among the highest.

This study describes malpractice risk among US pediatricians using data from a nationwide liability insurer covering 1630 pediatricians from 1991 to 2005. It compares pediatric malpractice experience with other specialties and studies patient factors associated with pediatric malpractice claims. (Read the full article)

Studies reveal that mothers of infants with colic (defined by Wessel’s criteria of >3 hours per day of distress) are more likely to develop depression. No studies have examined whether the consolability of infant crying predicts maternal depression risk.

Prolonged inconsolable infant crying has a stronger association with maternal depressive symptoms than overall daily duration of fussing and crying, suggesting that a mother’s report of inability to soothe her infant may be a powerful indicator of her depression risk. (Read the full article)

Infants with a diverse gut microbial flora are less likely to develop eczema and allergy.

Parental sucking of their infant’s pacifier is associated with a reduced risk of allergy development and an altered oral flora in their child. Transfer of oral microbes from parent to infant via the pacifier might be used in primary prevention. (Read the full article)

Distracted driving due to texting while driving (TWD) has emerged as an important teenage safety issue. Previous studies have shown that the self-reported prevalence of TWD among teenagers varies widely.

In 2011, 45% of US high school students aged ≥16 years reported TWD during the past 30 days. TWD was positively associated with other risky motor vehicle behaviors; this association strengthened as frequency of TWD increased. (Read the full article)

The importance of transition from pediatric to adult health care for youth with special health care needs has gained increasing attention over the past decade, but fewer than half of this population received needed transition preparation in 2005–2006.

This study reports on transition findings from the 2009–2010 National Survey of Children with Special Health Care Needs and finds no discernible improvements since 2005–2006. New clinical recommendations and care processes should help to accelerate transition improvements in the future. (Read the full article)

Before the introduction of conjugate pneumococcal vaccines and routine penicillin prophylaxis, febrile patients with sickle cell disease were known to have a 3% to 5% risk of bacteremia. Consequently, hospitalization rates for febrile episodes are >70%.

We observed no mortality or morbidity among those managed completely as outpatients, and bacteremia occurred in <1%. Physicians should strongly consider outpatient management of febrile children with sickle cell disease if there are no other indications for admission. (Read the full article)

The American Academy of Pediatrics recommends that all preterm infants receive human milk; however, little is known about the use of human milk in US advanced care neonatal units.

Routine use of human milk and use of donor milk in neonatal advanced care units increased from 2007 to 2011, particularly among units providing intensive care. There is geographic variation in the use of human milk in these units. (Read the full article)

Cognitive behavioral therapy is an effective and safe treatment of chronic fatigue syndrome in children and adolescents. After 6 months, Internet-based cognitive behavioral therapy in the form of FITNET led to an 8 times higher chance of recovery compared with usual care.

The positive effects of FITNET were maintained at long-term follow-up (>2.5 years).Patients following usual-care treatment achieve similar recovery rates at long-term follow-up. (Read the full article)

Public health policy focuses on reducing formula use for breastfed infants during the birth hospitalization. Observational evidence supports this approach, but no previous studies have examined the effect of early use of small volumes of formula on eventual breastfeeding duration.

Use of limited volumes of formula during the birth hospitalization may improve breastfeeding duration for newborns with high early weight loss. Reducing the use of formula during the birth hospitalization could be detrimental for some subpopulations of healthy term newborns. (Read the full article)

Universal oxygen saturation screening by pulse oximetry is now recommended for early detection of critical congenital heart disease. The distribution of saturations in asymptomatic newborns in a large population has not been described.

Our study is the largest to date to establish simultaneous pre- and postductal oxygen saturation nomograms in asymptomatic newborns at ~24 hours after birth. The mean postductal saturation is higher than preductal during this time. (Read the full article)

Pharmacologic treatment with sapropterin dihydrochloride (6R-tetrahydrobiopterin; BH4) has been an effective option for some phenylketonuria patients since its approval by the US Food and Drug Administration in 2007 and the European Medicines Agency in 2008.

This retrospective multicenter study revealed the long-term effects of sapropterin on metabolic control, dietary tolerance, and the outcome of BH4-responsive phenylketonuria patients harboring specific phenotypes and genotypes. It also confirmed that the minor adverse events disappeared by lowering the dose. (Read the full article)

Abdominal pain is a frequent complaint in pediatric emergency departments, with a broad differential diagnosis. The impact of demographic and clinical characteristics of patients on the evaluation and management of these children is not well known.

The most common cause of abdominal pain is constipation, which rarely requires hospital admission. Demographic factors, in particular race, do not seem to affect evaluation and management. (Read the full article)

Child welfare data show declines in child physical abuse since the early 1990s, but analysis of national data from hospitalized children in the Kids’ Inpatient Database showed an increased incidence of serious physical abuse in children from 1997 to 2009.

We found no significant change in hospitalization rates for injury from abuse in young children and increases in injury severity using the National Inpatient Sample from 1997 to 2009. This data helps provide a more complete perspective of the problem. (Read the full article)

Cross-sectional studies in children and adults have reported a significant positive association between attention-deficit/hyperactivity disorder (ADHD) and obesity.

This controlled, prospective, follow-up study of boys with ADHD found significantly higher BMI and obesity rates in adulthood, compared with men without childhood ADHD, regardless of socioeconomic status and other lifetime mental disorders. (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)

Many US children aged 6 to 24 months who would be classified as low weight-for-age by the Centers for Disease Control and Prevention 2000 reference will be classified as normal weight-for-age by the World Health Organization 2006 standard.

Children who will be reclassified from low to normal weight-for-age using the World Health Organization growth standard are at higher risk of adverse health outcomes than children who are not low weight-for-age by the Centers for Disease Control and Prevention reference. (Read the full article)

Sleep patterns of adult monozygotic twins are more similar than those of dizygotic twins, showing moderate heritability and little effects of environmental influences. There have been very few genetically informative studies of sleep in preschool children and results appear inconsistent.

From previous studies, we investigated daytime and nighttime continuous sleep duration longitudinally. This is the first time that the etiologies of daytime and nighttime continuous sleep duration trajectories were studied in early childhood. (Read the full article)

Infants aged <2 months are at highest risk for pertussis morbidity and mortality but are too young to receive pertussis vaccines. To protect young infants, the Advisory Committee on Immunization Practices recommends mothers receive 1 dose of Tdap during pregnancy.

This article evaluates the effect of Tdap during pregnancy compared with postpartum Tdap and cocooning in preventing infant pertussis cases, hospitalizations, and deaths, as well as their relative cost-effectiveness. (Read the full article)
