Adherence to guidelines has generally been shown to improve patient care and reduce the cost of care. Current understanding of the varying reasons why clinicians deviate from guidelines is based on surveys and retrospective reviews.

We examined clinician deviations from guidelines in a prospective fashion and attempted to categorize those deviations. Better elucidation of clinician reasoning behind deviations may inform care improvement and help define strategies to eliminate unjustifiable deviations. (Read the full article)

The rapidly rising prevalence of overweight and obesity among children and adolescents over the past 4 decades is a significant public health concern. Experts urge pediatric health care providers to provide routine obesity screening and counseling.

We provide the first nationally representative estimates of the rate of screening and counseling for adolescent obesity by pediatric health professionals. We also examine how socioeconomic factors and access to health care affect whether adolescents receive these services. (Read the full article)

Group B Streptococcus (GBS) is a common cause of meningitis in young infants. Studies from the 1980s revealed that GBS meningitis resulted in substantial mortality and reported that survivors of the infection had a high likelihood of adverse neurodevelopmental outcome.

Contemporary long-term outcomes for children surviving GBS meningitis reveal that 56% are functioning normally. The remainder sustained mild-to-moderate (25%) or severe (19%) neurodevelopmental impairment, highlighting the need for GBS prevention and for ongoing developmental follow-up for GBS meningitis survivors.

Preterm children born between 29 and 36 gestational weeks are at higher risk of developmental delay. The Ages and Stages Questionnaires (ASQ) have been recommended as a developmental screening tool.

At 12 months’ corrected age (CA), the ASQ was insufficient in identifying delays on both mental and psychomotor scales of the Bayley Scales of Infant Development but was accurate in detecting mental delay at CA of 24 months. (Read the full article)

Known rates of nonsuicidal self-injury, hurting oneself without the intent to die, are between ~7% and 24% in samples of early adolescents and older adolescents, yet research has not reported rates for youth younger than 11 years old.

Children as young as 7 years old report engaging in nonsuicidal self-injury. There is a grade by gender interaction for nonsuicidal self-injury, such that ninth-grade girls report the greatest rates of engagement and do so by cutting themselves. (Read the full article)

Neonatal hearing screening occasionally fails because of several perinatal and neonatal factors. However, the effect of mode of delivery on hearing screening has not yet been established.

We show significantly more failures on hearing screening in cesarean delivery infants. Hence, the timing of screening after cesarean delivery should preferably be postponed beyond 48 hours to improve success rate, minimize maternal anxiety, and decrease costs. (Read the full article)

Providers who speak Spanish, regardless of their proficiency level, may use Spanish for clinical care without seeking professional interpretation. Failure to use professional interpretation increases the risk for miscommunication and can lead to patient harm.

Providing residents with objective feedback on Spanish language proficiency decreased willingness to use Spanish in straightforward clinical scenarios. Language proficiency testing, coupled with institutional policies requiring professional interpretation, may improve care for patients with limited English proficiency. (Read the full article)

Regular use of an integrated personal health record (PHR) may lead to improved outcomes through improved care coordination, communication, and patient empowerment. A limited number of studies have examined integrated PHR use for children.

Parents of children with chronic disease appear willing to use an integrated PHR to address health care needs for their child. PHRs may lead to improved health care and outcomes by enabling more coordinated care for children with chronic disease. (Read the full article)

Early speech and language delays are risk factors for later developmental and social difficulties. It is easier to identify them retrospectively than prospectively. Population characteristics and prevalence rates make screening problematic.

Using data from a birth cohort, this study identifies predictors of language performance at 5 years and 4 patterns of change between 3 and 5 years, comparing those who change with those whose profile remains low across time points. (Read the full article)

A wide variety of prescription drugs are prescribed to US children. Although one of the steps in assessing the risk/benefit of therapies in the pediatric population is to understand how they are used, pediatric drug utilization is not well characterized.

By using large prescription databases, this study examines the frequency and patterns of national outpatient drug utilization (acute and chronic medications) in US infants, children, and adolescents for 2002 through 2010. (Read the full article)

Parents are increasingly following alternative immunization schedules. Current studies suggest up to 21% of parents in the United States are intentionally delaying or refusing some or all of the recommended early-childhood vaccines.

This is the first study to use Immunization Information System data to quantify the proportion of children consistently delaying receipt of vaccines. Consistent-limiting children were found to have lower levels of recommended vaccines. (Read the full article)

Male circumcision reduces risk of HIV acquisition in men by 60% and is associated with other health benefits. Compared with adult circumcision, infant male circumcision is safer, less expensive, and represents a cost-saving intervention for HIV prevention in many settings.

IMC is little known in East Africa and is not routinely practiced. This is the first study to assess acceptability and uptake of IMC in East Africa among parents who were actually offered the procedure. (Read the full article)

Chronic fatigue syndrome (CFS) is a disabling illness. Some children with chronic disabling fatigue are housebound. Some primary care physicians find making the diagnosis of CFS difficult.

Chronic disabling fatigue is more common in 13-year-olds than previously realized with a population prevalence of ~2.0%. Chronic disabling fatigue in teenagers is more common in those with higher levels of early family adversity. (Read the full article)

Literature about polymorphic expression of an apparent life-threatening event (ALTE), particularly that concerning discrimination between ALTE with evident cause and idiopathic ALTE, is scarce. Relationships between SIDS and ALTEs have been supposed but data are still controversial and no genetic data are available.

Genetic analysis (5HTT and MAOA) on ALTEs and idiopathic ALTEs discriminated the 2 syndromes and found a link between the idiopathic form and SIDS. Consequently, we hypothesized that the 2 latter syndromes could be different phenotype expressions of a common genetic base. (Read the full article)

Children with a single kidney are often counseled to avoid contact/collision sports based on the concern of injury to the kidney; however, the incidence of kidney injury during sport is not well understood.

Based on this multiyear, prospective injury surveillance system of varsity-level high school athletes, sport-related kidney injury is rare. Reevaluation of American Academy of Pediatrics recommendations regarding sport participation by children with a single kidney is indicated. (Read the full article)

Emphasis on preventing central line-associated bloodstream infections (CLABSIs) in US health care facilities and prophylactic antifungal medication use in neonates may impact incidence of Candida spp. CLABSIs. However, data on trends in incidence of neonatal Candida spp. CLABSIs are lacking.

Data from a large sample of US NICUs was analyzed to assess trends in incidence over time. This analysis provides a description of the epidemiology of Candida spp. CLABSIs in a national health care-associated infections surveillance system. (Read the full article)

Febrile infants in the first 90 days may have life-threatening serious bacterial infection. Well-appearing febrile infants with serious bacterial infections cannot be distinguished from those without by examination alone. Variation in care resulting in both undertreatment and overtreatment is common.

The systemwide implementation of an evidence-based care process model for the care of febrile infants in Intermountain Healthcare was associated with increased delivery of evidence-based care, improved infant outcomes, and lower costs. This model adopted nationally can improve value. (Read the full article)

Infant malnutrition is known to be associated with behavioral and cognitive impairment throughout childhood, adolescence, and young adulthood. However, controlled studies addressing adult outcomes in middle life, including earning potential, educational attainment, and standard of living, are limited.

A discrete episode of moderate to severe malnutrition in infancy, with good rehabilitation thereafter, is associated with lower adult social status and a widening income gap relative to healthy controls, partially attributable to cognitive impairment in the previously malnourished. (Read the full article)

There is no literature on the concentrations of vitamin B₆ vitamers in cerebrospinal fluid of preterm and term newborn infants. This knowledge, however, is highly important, because vitamin B₆ plays a pivotal role in brain development and functioning.

In cerebrospinal fluid of newborn infants, B₆ vitamer concentrations are strongly dependent on postmenstrual age, indicating that vitamin B₆ homeostasis in brain differs between preterm and term newborns. This has implications for the evaluation of epilepsy and vitamin B₆ deficiency. (Read the full article)

Celiac disease is an immunologic disorder with autoimmune features. Sweden experienced an epidemic of celiac disease in infants (1984–1996). Early vaccinations might influence the risk for autoimmune diseases, and could potentially have contributed to celiac disease risk and the epidemic.

Early vaccinations within the national Swedish program are not risk factors for celiac disease, nor do changes over time contribute to explaining the Swedish epidemic. A protective effect by vaccination against tuberculosis (bacillus Calmette-Guérin) is suggested. (Read the full article)

Neonatal hyperbilirubinemia may progress to bilirubin encephalopathy. Findings from previous studies on long-term development of neonatal hyperbilirubinemia are conflicting.

Using Ages and Stages Questionnaire, we observed no association between bilirubin exposure and overall development in 1- to 5-year-old children who in the neonatal period had total serum bilirubin level ≥25 mg/dL and no or only minor neurologic symptoms. (Read the full article)

Preterm infants from 33 gestational weeks can detect specific shape features (prism and cylinder) by touch (without visual control), and remember them; however, nothing is known about such abilities earlier in development.

The preterm infant, even when very immature (from 28 gestational weeks), is endowed with tactile sensory abilities: the exploration and memorization of an object by touch, the discrimination of a novel object, and the recognition of a familiar object after interference. (Read the full article)

Infants and children with diagnosed food allergy are at risk for acute, potentially life-threatening symptoms. Limited data are available on the frequency, severity, and circumstances of reactions and caretaker medical response.

This study describes food allergy reaction frequency, circumstances, and response. Pitfalls that may inform improved anticipatory guidance included lack of vigilance, misreading ingredient labels, allergen cross-contact, nonaccidental allergen feeding, and underutilization of epinephrine for severe reactions.

Various studies have documented marked racial/ethnic disparities in children’s receipt of dental services at single time points or brief periods.

This study reveals significant improvements in children’s receipt of dental care overall, as well as a dramatic narrowing of African American/white disparities in children’s receipt of dental services over the last 40 years in the United States. (Read the full article)

Rotavirus vaccine efficacy is lower in low-income settings with the highest child mortality due to diarrhea. In recently published clinical trials of rotavirus vaccines in Africa, waning of efficacy was also noted among children aged ≥1 year.

These data offer the first evidence of the duration of protection of the pentavalent rotavirus vaccine against severe rotavirus disease after routine use of the vaccine in a developing country setting. (Read the full article)

Comprehensive lifestyle interventions for adolescent weight management, including diet, physical activity, and behavioral intervention, have been found to demonstrate modest, short-term success. However, very little is known about the long-term effectiveness of adolescent behavioral weight management trials.

This randomized controlled trial demonstrates that two 16-week group-based behavioral weight loss programs, when combined with either aerobic exercise or peer-based adventure therapy, produced sustained improvements in BMI among overweight/obese adolescents through 24 months. (Read the full article)

Late preterm infants are at risk for a variety of developmental impairments; however, little is known about developmental differences among children born within the term range of 37 to 41 weeks’ gestation.

This study links comprehensive birth record data from 128 050 term births to children’s school records 8 years later. Analyses establish that, even among the "normal term" range, gestational age is an important independent predictor of academic achievement. (Read the full article)

Childhood abuse has been associated with obesity risk in adulthood. Little is known regarding the impact of abuse severity on risk, potential mechanisms are poorly understood, and few studies have been conducted among minority populations.

Severity of child/teenager physical and sexual abuse is associated with increased risk for adult obesity and/or central adiposity in adulthood. These are the first such findings in a large cohort of US black women. (Read the full article)

Sudden cardiac death in young athletes is an uncommon but devastating event. Addition of routine electrocardiogram (ECG) screening to standard preparticipation care may reduce the number of sudden deaths. Lack of data regarding effectiveness and costs has prevented widespread implementation.

Adding ECG screening to current preparticipation evaluation is not cost-effective. Cost is driven primarily by the evaluation of the large number of false-positive findings. An ECG-only screening strategy is more cost-effective. (Read the full article)

Physical punishment is associated with aggression, delinquency, and internalizing conditions in childhood, as well as a range of Axis I mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and mental health.

To our knowledge, this is the first nationally representative examination of physical punishment and a range of Axis I and II disorders, gender interactions, and proportion of mental disorders in the general population that may be attributable to physical punishment. (Read the full article)

Moderately preterm-born children (32–35^6/7 weeks’ gestation) are at risk for both neonatal morbidities after birth and developmental delays in early childhood. It is unknown whether neonatal morbidities contribute to the developmental delays of this particular group.

Of all neonatal morbidities commonly seen in moderately preterm-born children, only hypoglycemia increased the risk of developmental delay after moderately preterm birth. A concerted effort to prevent hypoglycemia after birth might enhance developmental outcome in this group. (Read the full article)

Siblings and other contacts of abused children, especially twins, are thought to be at higher risk for abuse than other children. However, the rate at which screening tests identify injuries in contacts is currently unknown.

Contacts of abused children with serious injuries have fractures identified on skeletal survey at significant rates. Twins are at substantially increased risk for fracture. Physical examination findings were not sensitive for fractures. (Read the full article)

Respiratory infectious symptoms are common during the first year of life. Day care attendance, older siblings, and lack of breastfeeding have been considered as possible factors influencing early respiratory tract infections.

Children with early dog contacts seem to have fewer infectious respiratory symptoms and diseases, especially otitis, during the first year of life. (Read the full article)

This research presents the first 2 experimental studies on the short-term effects of smoking portrayal in movies on children’s beliefs about smoking.

Exposure to movie smoking from cartoon and family-oriented movies had no effect on implicit associations toward smoking. For smoking beliefs, effects were again small and only statistically significant for social norms regarding smoking. (Read the full article)

Clinical trials have demonstrated that prophylactic human papillomavirus (HPV) vaccines are highly effective in preventing HPV infection, but the impact of vaccination on HPV prevalence rates in real-world, community settings is uncertain.

This study provides evidence of a substantial decrease in the prevalence of vaccine-type HPV among young women and evidence of herd protection in a community only 4 years after the quadrivalent HPV vaccine was licensed. (Read the full article)

Data suggest that delivery at high-volume, high-technology hospitals reduces neonatal mortality. No study has examined other complications or compared the effects in multiple states by using a study design to control for unmeasured differences in case mix.

The survival benefit to delivering at a high-level NICU between 1995 and 2005 is larger than previously reported and varies between states. The survival benefits affect both extremely and moderately preterm infants. Complication rates were similar between hospital types. (Read the full article)

Adolescent dating violence has been studied from the perpetrators' and survivors' perspectives. The risk and protective factors have been explored, and the strength of the association of these factors with adolescent dating violence has been adequately described.

This study assessed the perceptions and practices of school counselors on adolescent dating violence. Knowing school personnel’s practices and perceptions may help researchers and practitioners gain insights into possible ways to alleviate the problem of dating violence in adolescents.

The US Surgeon General has determined that the relationship between movie smoking exposure (MSE) and youth smoking is causal; however, it is not known whether movie rating influences how adolescents respond.

The response to PG-13–rated MSE was indistinguishable from R-rated MSE. An R rating for smoking could reduce smoking onset in the United States by 18% (by eliminating PG-13 MSE), an effect similar to making all parents maximally authoritative in their parenting. (Read the full article)

A dose-response relationship exists between light irradiance and decrease of total serum bilirubin concentration (TsB) at relatively low irradiances. It has been questioned whether by increasing irradiance a "saturation point" exists, above which no further decrease of TsB is seen.

We found a linear relation between light irradiance in the range of 20 to 55 μW/cm²/nm and decrease in TsB after 24 hours of therapy, with no evidence of a saturation point. (Read the full article)

Although the impact of changes in the economy on child physical abuse rates is not well understood, there is concern that increased numbers of children may have been victims of physical abuse as a result of the recent economic recession.

Results of this study demonstrate that the rate of admissions for physical abuse to pediatric hospitals has increased during the past 10 years and suggest an association between that increase and the housing mortgage crisis. (Read the full article)

Among adolescents, weight status has been inversely associated with sports participation but not active commuting or physical education. Studies of each form of physical activity have not included adequate adjustments for other physical activities, previous body weight, or diet quality.

Estimates indicate overweight/obesity and obesity prevalence would decrease by 11% and 26%, respectively, if adolescents played on at least 2 sports teams per year; obesity prevalence would decrease by 22% if adolescents walked/biked to school 4–5 days per week. (Read the full article)

Dental composites composed of bisphenol A (BPA) derivatives are common alternatives to amalgam, but may release BPA. Gestational BPA exposure has been associated with poorer behavior in children. A safety trial of amalgam found worse psychosocial outcomes for children randomized to composites.

In the trial, greater exposure to bisphenol-A-glycidyl-methacrylate-based dental composite in children aged 6 to 10 years was associated with worse self-reported psychosocial functioning at 5-year follow-up. There were no such associations with exposure to dental amalgam or urethane-dimethacrylate-based polyacid-modified composite (compomer). (Read the full article)

Persistent facial nerve palsy is a well-described neurologic deficit after Lyme neuroborreliosis and occurs in 13% to 20% of children. Other neurologic deficits are less closely described. Nonspecific subjective symptoms are reported as often among patients as controls in previous short-term follow-up studies.

Persistent neurologic deficits, other than facial nerve palsy, were found in 14% of patients, causing impaired fine motor skills, poor balance, or persistent pain. Nonspecific subjective symptoms were reported as often among patients as controls in this long-term follow-up study and should not be considered as sequelae after Lyme neuroborreliosis.

Eating disorder not otherwise specified (EDNOS) is the most common eating disorder diagnosis. Binge eating disorder, 1 type of EDNOS, is associated with obesity among adults. Little is known about the health outcomes associated with other types of EDNOS.

This is the first study to evaluate the prospective association of full and subthreshold bulimia nervosa, binge eating disorder, purging disorder, and other EDNOSs with specific mental and physical health outcomes. (Read the full article)

Macromastia is associated with severe physical and emotional symptoms and negatively impacts health-related quality of life in adult women. Reduction mammaplasty is the most effective treatment for adults. Little is known regarding the impact of macromastia during adolescence.

Adolescents with macromastia have impaired health-related quality of life, lower self-esteem, more breast-related symptoms, and are at higher risk for disordered eating in comparison with their peers. These negative health outcomes have implications for early intervention in this patient population. (Read the full article)

Many drugs are not approved for use in pediatric patients and there is limited evidence on their safety and efficacy in children. Furthermore, there is concern that the quality of pediatric trials is inferior compared with adult trials.

For conditions with a high disease burden in children, only a small proportion of clinical drug trials study pediatric patients. Most pediatric trials are not funded by industry, and the deficiency of evidence is largest in developing countries. (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)

Percentile charts for birth weight are used to assess the somatic development of neonates (small, appropriate, or large for gestational age).

A systematic error was identified in the majority of birth weight percentile charts. As a consequence, small for gestational age rates are overestimated and large for gestational age rates are underestimated; ~5% of neonates are misclassified. (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)

Childhood obesity is already prevalent by preschool age, particularly among Latinos. Parents have tremendous influence on factors that contribute to childhood obesity (eg, diet, physical activity); thus, family plays a crucial role in pediatric obesity prevention.

This randomized controlled trial examined the effect of a behavioral intervention involving Latino-American parent–preschool-aged child dyads. The intervention resulted in reductions in absolute BMI across the 3-month study period, with patterns suggesting the largest effect for obese children. (Read the full article)
