Some but not all randomized trials have shown effects of probiotics on incidence and duration of diarrhea and respiratory tract infections among children in developing countries. Calcium improves resistance to intestinal infections in adults, but efficacy in children is unknown.

Lactobacillus reuteri DSM17938 may prevent diarrhea, especially in children with lower nutritional status. Regular calcium milk, alone or with Lactobacillus casei CRL431, did not reduce diarrhea. None of the interventions affected respiratory tract infections in these Indonesian children. (Read the full article)

Preterm, growth-restricted infants are at high risk of necrotizing enterocolitis (NEC). NEC occurs most frequently in infants who have received enteral feeds. It is common practice to delay introduction of enteral feeds in these infants.

Early introduction of enteral feeds results in earlier achievement of full enteral feeding. Early feeding is not associated with a higher risk of NEC. Delayed feeding is associated with a higher risk of cholestasis. (Read the full article)

Although all residents progressively assume responsibility for clinical skills under the teaching and supervision of attending physicians, senior residents also assume responsibility for teaching and supervising. This leads to a dynamic negotiation of responsibilities, particularly on clinical work rounds.

A better understanding of how attending physicians and senior residents negotiate shared responsibilities for teaching and supervising, and the context in which this negotiation occurs, may clarify assumptions and set expectations for resident training. (Read the full article)

Trisomy 13 and trisomy 18, common chromosomal abnormalities, are generally considered fatal within the first year after birth, although some children live longer. Little is known, however, about the inpatient medical courses of these infants and children.

Evaluation of nationally representative hospitalization data demonstrates that a significant number of children with trisomy 13 and trisomy 18 live beyond 1 year of age and that the care they receive includes both medical and surgical treatments. (Read the full article)

During prenatal counseling for prematurity, information is provided to expectant parents to empower them to participate in the medical-care decision-making regarding their child. However, numerous studies have shown that providing information effectively during preterm labor is challenging.

The current study provides evidence that effectiveness of counseling can be improved by providing written information to parents before the face-to-face verbal counseling. Appropriately presented, detailed information improves knowledge and decreases maternal anxiety. (Read the full article)

Alcohol consumption during adolescence and early adulthood has been associated with an increased risk of biopsy-confirmed benign breast disease (BBD), an established risk factor of breast cancer.

This is the first study to analyze the association between adolescent alcohol consumption and risk of biopsy-confirmed proliferative BBD by adolescent folate intake. The result provides no evidence for protective effects of adolescent folate intake on risk of alcohol-associated BBD. (Read the full article)

Clinical decision support systems offer a way to help physicians use evidence-based guidelines for screening. Screening patients for common developmental, psychosocial, and behavioral issues informs the clinical decision-making process and may improve patient outcomes.

The Child Health Improvement through Computer Automation system, a clinical decision support system and an electronic medical record, is able to effectively screen patient families in the waiting room by using a tailored questionnaire. The study reveals positive screening rates for identifiable risks in a very large representative urban population by using Child Health Improvement through Computer Automation’s questionnaire.

In utero exposure to glucocorticoids in animal models influences vascular development. Studies in young adults have shown that exposure to antenatal glucocorticoids alters glucose metabolism, but it is not known whether there are any cardiovascular effects.

Glucocorticoid exposure is associated with a localized increase in aortic arch stiffness, similar in magnitude to term-born individuals a decade older. The change in stiffness does not relate to changes in glucose metabolism that were also evident in this cohort. (Read the full article)

High or low lymphocyte counts at birth have been reported as a marker for subsequent intraventricular hemorrhage, retinopathy of prematurity, and periventricular leukomalacia. However, this conclusion is questionable because reference ranges for lymphocyte counts have not been constructed by using large numbers of neonates.

This study provides reference ranges for lymphocytes of neonates. A high count at birth is associated with early onset sepsis and IVH and a low count with early onset sepsis, IVH, and retinopathy of prematurity. Among neonates with birth asphyxia, a low count identifies a high risk for death. (Read the full article)

Estimates of youth participation in strangulation activity, commonly referred to as the "choking game," range from 5% to 11%. Previous studies have documented correlations between youth choking game participation and health risks such as substance use and mental health issues.

Among Oregon eighth-graders surveyed, >6% had ever participated in the choking game. Participation was linked to poor nutrition and gambling among females, exposure to violence among males, and sexual activity and substance use among both genders. (Read the full article)

Nonadherence to antiretroviral therapy among children and youth with HIV is a frequent problem that can result in treatment failure and disease progression for this population. Children and adolescents face different barriers to adherence than adults infected with HIV.

Few studies have examined specific barriers to adherence as reported by children with perinatally acquired HIV and their caregivers. This report examines the agreement between child and caregiver perceptions of adherence barriers and the factors associated with these barriers. (Read the full article)

Rural Alaska children have high rates of hospitalization with lower respiratory tract infections from a variety of pathogens. Past studies of risk factors for respiratory syncytial virus infection associated medically high-risk status, household crowding, and infant feeding practices with hospitalization.

This study reveals the importance of medically high-risk status and infant feeding practices as important factors in respiratory hospitalization. In addition, we identified woodstove use and the absence of 2 or more sinks in household as risk factors for hospitalization. (Read the full article)

Cross-sectional imaging can reduce the negative appendectomy rate (NAR) in children being evaluated for suspected appendicitis; however, the ability of diagnostic imaging to decrease NAR may vary by age and gender.

Cross-sectional imaging leads to a significant reduction in NAR for children younger than 5 years and girls older than 10 years. For boys older than 5 years being evaluated for uncomplicated appendicitis, advanced imaging appears to have limited value. (Read the full article)

We know that many evidence-based treatments for acute asthma are underused, and adherence with treatment guidelines is poor; however, studies have focused on β₂ agonists and corticosteroids, but little is known about intravenous magnesium, which has substantial evidence of benefit.

Magnesium is used infrequently in Canadian pediatric emergency departments in hospitalized children with acute asthma, with variation across sites. More than half of this population does not receive frequent bronchodilators and timely corticosteroids. (Read the full article)

As a result of safety and environmental concerns about mercury, aneroid sphygmomanometers have replaced mercury-filled devices for blood pressure measurements. Despite this change, few studies have compared the 2 devices.

Little clinical variation exists between blood pressure measurements obtained from an aneroid or mercury device, suggesting that either device could be used in a research or clinical setting. (Read the full article)

Valid parental permission requires that the decision be both informed and voluntary. Previous research has focused on the informational components of decision-making (eg, disclosure and understanding), with little empirical attention to the voluntariness of decisions.

We address this gap by examining the voluntariness of parents making research or treatment decisions in pediatric oncology. We identify demographic and contextual correlates of voluntariness and highlight the clinical implications of the findings for physicians and investigators. (Read the full article)

Evaluating dehydration severity is a challenging task. Clinical dehydration scores that combine multiple clinical findings are promising. One clinical dehydration scale score has been developed and subsequently evaluated; however, few participants in the derivation and validation studies were significantly dehydrated.

In children requiring intravenous rehydration, the dehydration scale displayed moderate reliability and weak associations with objective measures. Thus, although the scale can assist in assessing dehydration, it should not be used in isolation to dictate interventions (eg, intravenous rehydration, hospitalization). (Read the full article)

Cross-sectional studies have demonstrated associations between the white matter injury and cognitive impairment in very preterm born children. Longitudinal studies confirmed the relationships between cerebral MRI at term and neurodevelopmental outcomes at up to 2 years old.

White matter injury (but not gray matter injury) on term MRI predicted cognitive impairments of very preterm born infants at 9 years old. Qualitative assessment of white matter signal intensities showed limited predictive values of cognitive impairments. (Read the full article)

Disparities are known to exist in the prescription of opioid analgesics among racial and ethnic groups in the management of postoperative, cancer, and emergency department pain in patients across all ages, including children.

Race is associated with an unequal burden of perioperative pain and opioid adverse effects in children. Relatively, African American children had higher postoperative pain, and Caucasian children had higher incidences of opioid related adverse effects. (Read the full article)

Although several randomized trials have examined the efficacy of serotonin receptor inhibitors in the treatment of repetitive behaviors, there still remains clinical uncertainty as to whether these agents are effective in treating such behaviors in children and adults with autism spectrum disorders.

The goal of this meta-analysis was to examine randomized trials of serotonin receptor inhibitors for treating repetitive behaviors in autism spectrum disorders. Although a small but significant effect of these agents was observed, this effect is likely due to the selective publication of trial results. (Read the full article)

We lack prospective studies documenting "dosage effects" of chronic child maltreatment for both subsequent adolescent and adult outcomes. It is unknown whether effects are linear, shelving, or exponential, and we lack data across domains of outcomes.

Chronic child maltreatment reports are a robust indicator of future negative health and behavioral outcomes. There is a dose-response relationship between chronicity and outcomes in adolescence, but this is attenuated in adulthood once adverse child outcomes are controlled. (Read the full article)

Following a rapid increase from 1980 to 2001, the prevalence of obesity among school-age children and adolescents in the United States has plateaued. Few studies have examined obesity trends among younger children in the past decade, and findings are inconsistent.

Among children aged <6 years at this multisite pediatric practice, the prevalence of obesity was fairly stable during 1999–2003, but substantially decreased during 2004–2008. This decrease was smaller among children insured by Medicaid than children insured by non-Medicaid health plans. (Read the full article)

Existing clinical research policy does not guarantee availability of results. Registration on the Web site ClinicalTrials.gov and the Food and Drug Administration Amendments Act improved transparency in pediatric clinical research. Registration and publication remain voluntary for many trials involving children.

Only 29% of completed registered studies and 53% of National Institutes of Health–funded trials involving children were published. Numbers of studies are increasing. Registration and posting of results on ClinicalTrials.gov should be mandatory for all studies involving children. (Read the full article)

Kindergarten entry vaccination requirements are associated with higher coverage for early childhood vaccines.

Middle school entry vaccination requirements may also be associated with higher coverage for adolescent vaccines, whereas education-only requirements appear not to have an impact at this time. (Read the full article)

The National Vaccine Advisory Committee highlighted the importance of settings complementary to the medical home for immunization delivery among adolescents, including school-based health centers (SBHCs). The effectiveness and cost of recall for immunizations in SBHC settings has not been studied.

SBHC-based recall was effective in improving immunization rates among adolescents, with effects sizes exceeding those achieved in practice settings. Average costs per child who was immunized ranged from $1.12 to $2.34 in 3 schools, but was $6.87 in 1 school. (Read the full article)

Assessing for adequacy of supervision in the clinical setting is challenging and may result in significant variability in care. Clinicians must quickly decide if a child and family necessitate direct counseling, further intervention, or require reporting to state agencies.

This study identified the most important characteristics for the evaluation of the adequacy of supervision of a young child. A standardized scale using these characteristics may result in an efficient means to reduce variability in care. (Read the full article)

Rates of coverage for recommended vaccinations in adolescents are substantially lower than Healthy People 2010 goals. Reminder/recall is an evidence-based strategy that is proven to increase immunization rates in both adults and young children.

This study shows that reminder/recall is effective in increasing adolescent immunization rates. Practices may also benefit financially from conducting reminder/recall in this age group if they are able to generate additional well visits and keep supply costs low. (Read the full article)

Primary care settings provide an important venue for early detection of substance use and intervention, but adolescent screening rates need improvement. Screening and brief interventions appear effective in reducing adult problem drinking but evidence for effectiveness among adolescents is needed.

A computer-facilitated system for screening, feedback, and provider brief advice for primary care can increase adolescent receipt of substance use screening across a variety of practice settings, and shows promise for reducing adolescents’ use of alcohol and cannabis. (Read the full article)

Asthma disparities exist, with Latino children of Caribbean descent at risk for poor disease control. Controller medications reduce symptoms; however, medication adherence remains suboptimal. Identifying what factors predict poor medication adherence in at-risk groups could identify important treatment targets.

This study is the first to assess objective rates of medication use among children with asthma in Puerto Rico. Findings suggest that interventions incorporating family resources and addressing parental beliefs about medications may be of benefit across cultural groups. (Read the full article)

Dimenhydrinate, an antihistaminic agent, is a widely used drug in Canada and Europe. It limits stimulation of the vomiting center via the vestibular system. Multiple studies have shown its effectiveness in the treatment of vertigo and postoperative nausea and vomiting.

Dimenhydrinate, when given orally, did not significantly decrease the frequency of vomiting in children with acute gastroenteritis compared with placebo. The reported adverse effect proportions were similar for the dimenhydrinate and placebo groups. (Read the full article)

Information on infant safety after exposure to maternal antiretroviral regimens during pregnancy in international clinical trials is lacking. As antiretroviral drugs are released to populations in resource-limited settings through clinical trials, it becomes critical to collect pediatric outcome data.

The study demonstrates the feasibility of reporting infant outcomes following adult antiretroviral trials in developing countries, provides HIV-free infant survival and prospective growth data in association with maternal parameters, and details morbidity, mortality, and genetic defects following maternal antiretroviral exposure.

Omega-3 fatty acids (O3FA) are commonly used as complementary treatments in pediatric psychiatric disorders, including Tourette’s disorder (TD), and are well known to have anti-inflammatory properties. However, no studies to date have examined the effects of O3FA on pediatric TD.

This is the first double-blind, placebo-controlled clinical trial of O3FA in pediatric TD. The results indicate that O3FA supplementation may be beneficial in the reduction of tic-related impairment for some children and adolescents with TD, but not tics per se. (Read the full article)

Batteries, especially button batteries, are an important source of pediatric injury. Recent reports suggest that fatal and severe button battery ingestions are increasing.

An estimated 3289 battery-related ED visits occurred annually among US children <18 years of age, averaging 1 visit approximately every 3 hours. The number and rate of visits increased significantly during the 20-year study period, driven by increases during the last 8 study years. (Read the full article)

Some researchers have suggested that individuals with Down syndrome (DS) are protected from atherosclerotic disease; however, recent data from 2 large cohort studies of individuals with DS are significant for increased mortality from ischemic heart disease and cerebrovascular disease.

This study compares lipid profiles among children with DS and their siblings, highlighting the presence of a less favorable lipid profile in this high-risk population. (Read the full article)

Despite recommendations and a universal immunization program, a recent survey reported suboptimal influenza vaccination coverage in children aged 6 to 23 months in Ontario. Little is known about predictors of coverage in young children to target immunization strategies.

Full influenza vaccination coverage in young children in Ontario is <10% and declining since the 2006–2007 season. Medically high-risk children including low birth weight infants are more likely to be immunized, but maternal and health services characteristics remain important. (Read the full article)

Late-onset hypocalcemia is common in neonates, often presents with seizures or tetany, and is often attributed to transient hypoparathyroidism.

Late-onset hypocalcemia in neonates is often a sign of coexisting vitamin D deficiency and hypomagnesemia and is readily managed with therapy of limited duration, and neonates presenting with tetany or seizures due to hypocalcemia are unlikely to benefit from neuroimaging studies.

A single inhalation of laninamivir octanoate has previously been shown to be as effective as repeated doses of zanamivir in vitro and in vivo, but it is not known whether this is also the case for children.

Median time to fever resolution was not significantly different between laninamivir octanoate and zanamivir for pediatric patients with influenza. The severity of influenza symptoms and the frequency of complications were similar in the 2 groups. (Read the full article)

Overweight and obese children have a higher prevalence of several cardiovascular disease (CVD) risk factors. There is growing evidence demonstrating that CVD risk factors present during childhood persist into adulthood.

US adolescents had no significant change in prehypertension/hypertension and borderline-high/ high low-density lipoprotein cholesterol prevalence from 1999–2000 to 2007–2008; however, prediabetes/diabetes increased by 14%. (Read the full article)

Survival of children born with Down syndrome has been improving, but few studies have used population-based data to examine the influence of fetal and maternal characteristics on survival.

This study examined predictors of survival for children born with Down syndrome using population-based data from the UK Northern Congenital Abnormality Survey and shows that year of birth, gestational age, birth weight, and presence of additional anomalies influence survival status.

Most acute wheezing episodes in preschool children are associated with rhinovirus, which decreases extracellular adenosine triphosphate levels, leading to airway surface liquid dehydration and submucosal edema, which cause failure of mucus clearance. These children respond poorly to available treatments.

Hypertonic saline inhalation, a pro–airway surface liquid hydration therapy, significantly decreases both length of stay by 33% (1 day) and the absolute risk of hospitalization by 30% in preschool children presenting with acute wheezing episode to the emergency department. (Read the full article)

The association of retinal hemorrhages (RHs) with abusive head trauma (AHT) is robust; 46% to 100% RHs are reported in AHT. There is potential selection bias with risk of circular reasoning because the majority of studies describing RH focus on AHT.

This is the first prospective observational study defining prevalence and distribution of RH in critically ill children excluding those with AHT. Severe multilayered RH were rare and observed in children with accidental fatal head injury, severe coagulopathy, severe sepsis, or a combination of these factors. (Read the full article)

Neonatal follow-up programs are designed in part to identify developmental delays among high-risk infants after NICU hospitalization and make referrals to state-funded early intervention. Early intervention has been shown to benefit children with developmental delays.

Many high-risk infants demonstrating developmental delays at neonatal follow-up programs are not referred to early intervention. Subspecialty clinics share responsibility with the medical home in referring children from birth through three years with developmental problems to early intervention services.

The hypothesis that maternal prenatal folic acid lowers risk for childhood malignancy in offspring is supported by experimental and epidemiologic evidence, including 2 Canadian ecologic studies that showed inverse associations for some cancer types in the very young.

Examining Surveillance Epidemiology and End Results Program data, a decrease in the incidence of some childhood cancers (Wilms tumor, primitive neuroectodermal tumors) was observed in those <5 years after mandatory US folic acid fortification, with stronger effects detected in infants.

Although soy protein–based infant formula is known to support physical growth equal to that of infants fed cow's milk–based formula, data are lacking on developmental status of infants fed soy formula compared with breast milk or milk formula.

Infants fed soy protein–based formula scored within normal limits on standardized developmental testing and did not differ from infants fed cow’s milk–based formula. Breastfed infants have a slight advantage on cognitive development compared with formula-fed infants. (Read the full article)

Although morbidity-free survival for preterm infants has remained constant in US NICUs when assessed collectively, morbidity-free survival differs among centers. Center-specific practices before, at, or after delivery might affect outcomes of the most premature infants.

Our findings suggest that the approach taken to infants at the limits of viability is associated with outcomes of more-mature infants. Identifying centers with higher survival and lower morbidity might lead to identification of key practices to improve morbidity-free survival. (Read the full article)

Observation studies and short-term prospective intervention studies have shown that physical activity positively affects the accrual of bone mass and size during growth; however, fracture risk has not been evaluated.

This study reports the long-term results of a prospective intervention with increased physical activity at a population-based level and for the first time evaluated the clinical relevant end point, fracture risk. (Read the full article)

Children with specific language impairment are at risk for social difficulties. However, whether this occurs adaptively as a result of language impairment or occurs as a result of an underlying deficit in social cognition remains unclear.

We used eye tracking to explore how children with specific language impairment view social scenes. The overall gaze behavior resembled that of typically developing children. Significant attention to the speaker’s mouth may result in receiving less social-emotional information from the eyes. (Read the full article)

There is a paucity of controlled studies of recombinant factor VIIa (rFVIIa) use for off-label indications in pediatric patients. Data on the use of off-label rFVIIa, including safety and efficacy, are mostly limited to case reports or small case series.

This is the largest reported case series of off-label rFVIIa in pediatric patients from a well-designed, representative, and rigorously audited registry of rFVIIa use and describes the indications for use, dose administered, adverse events, and outcomes in 388 patients. (Read the full article)

Numerous studies report disparate use of dental services among poor children. National estimates vary based on the data source, and little is known about how age, race, and health plan affect use of dental services among Medicaid-enrolled children.

Based on of Medicaid claims, dental services improved since 2002 but varied substantially by state, age, and type of insurance. Children entering school had the highest prevalence of care as did children in primary care case management and health maintenance organizations. (Read the full article)

Although obesity is correlated with levels of systolic and diastolic blood pressure, there is little evidence if the increases in obesity over the last 40 years have resulted in increased blood pressure levels.

Despite increases in obesity in Bogalusa, Louisiana between 1974 and 1993, there was no increase in systolic or diastolic blood pressure levels. It should not be assumed that trends in high blood pressure have paralleled those for obesity. (Read the full article)
