There are no published prospective studies on the natural course and testicular growth in early childhood of spontaneously descended testes after birth compared with scrotal or surgically treated testes in boys with congenital cryptorchidism.

Data collected from this prospective study on the natural course and growth of the spontaneously descended testes add evidence-based data and recommendations on how to clinically manage boys with congenital cryptorchidism. (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)

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)

Neuropsychiatric conditions comprise a substantial and growing disease burden among children. Pharmacotherapy represents an important treatment option for these conditions, although most drugs are not approved for use in children.

Very few drug trials studying neuropsychiatric conditions focus on children. Furthermore, these trials examine and provide pediatric evidence for only a fraction of all available drugs in the treatment of common neuropsychiatric conditions. (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)

The ideal management of children with vesicoureteral reflux (VUR) remains a source of debate. There is little evidence to support many of the current management practices for children with VUR who have had 1 or 2 urinary tract infections.

Baseline associations, including bladder and bowel dysfunction and imaging studies, from the largest randomized, controlled trial conducted to date aimed at assessing the value of antimicrobial prophylaxis in children with urinary tract infection and VUR are presented. (Read the full article)

Obesity is associated with cardiometabolic risk factors and chronic conditions, such as type 2 diabetes. However, a proportion of overweight and obese youth remain free from cardiometabolic risk factors and are considered metabolically healthy.

This study provides insight into the determinants of cardiometabolic risk factors and the concept in health promotion of "fitness versus fatness." Hepatic lipid accumulation and not fitness level appears to drive cardiometabolic risk factor clustering among overweight and obese youth. (Read the full article)

Prenatal diagnosis and clinical examination do not identify all infants with critical congenital heart defects before hospital discharge. To improve early critical congenital heart defect detection, New Jersey was the first state to implement legislatively mandated newborn pulse oximetry screening.

This report is the first to evaluate statewide pulse oximetry screening implementation. New Jersey had a high statewide screening rate and identified 3 infants with previously unsuspected critical congenital heart defects that otherwise might have resulted in significant morbidity and mortality.

Physical punishment is associated with a range of Axis I and II mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and physical health.

To our knowledge, this is the first nationally representative examination of harsh physical punishment and physical health. Harsh physical punishment in the absence of child maltreatment is associated with higher odds of cardiovascular disease (borderline significance), arthritis, and obesity. (Read the full article)

Children with autism spectrum disorder (ASD) and those with ADHD are at risk for problematic video game use. However, group differences in media use or in the factors associated with problematic video game use have not been studied.

Boys with ASD and ADHD demonstrated greater problematic video game use than did boys with typical development. Inattention was uniquely associated with problematic use for both groups, and role-playing game genre was associated with problematic use among the ASD group only. (Read the full article)

Critical congenital heart disease (CCHD) was recently added to the US Recommended Uniform Screening Panel for newborns.

Routine screening could cost an estimated additional $6.28 per newborn and $40 385 per life-year gained. The incremental cost of screening might be approximately $0.50 per newborn with reusable sensors. Future analysis of newborn screening programs may help refine these projections.

Asthma is a common medical complication during pregnancy that is associated with an increased risk of adverse obstetric outcomes.

This study adds knowledge on potential long-term consequences of maternal asthma during pregnancy for offspring health, demonstrating that maternal asthma during pregnancy is linked to a wide spectrum of offspring diseases during childhood. (Read the full article)

Newborns with critical congenital heart disease (CCHD) are at risk for cardiovascular collapse or death if discharged from the birth hospital without a diagnosis. Newborn screening aims to identify CCHD missed in prenatal and postnatal examinations.

Birth hospital nursery level and CCHD type were found to be associated with late CCHD detection. Routine newborn screening could conceivably reduce differences in the frequency of late diagnosis between birth hospital facilities. (Read the full article)

Pulse oximetry screening at 24 hours of age improves detection of critical congenital heart disease in asymptomatic newborns.

This study describes an initial experience with pulse oximetry screening for critical congenital heart disease and provides a strategy for preparing for state implementation of recent federal newborn screening recommendations. (Read the full article)

The intestinal microbiome may play a role in immune system maturation, and it has been postulated that early-life probiotic administration may reduce the risk of allergies and asthma in childhood. To date, however, results from clinical trials have been inconsistent.

In this meta-analysis, administration of probiotics in early life may reduce total immunoglobulin E level and protect against atopic sensitization but do not seem to protect against asthma/wheezing. Future trials should carefully select probiotic strains and include longer follow-up. (Read the full article)

Pediatric myasthenia encompasses a group of rare and underdiagnosed conditions affecting the neuromuscular junction. Symptoms include fluctuating skeletal muscle weakness, which can progress to respiratory failure if left untreated. The autoimmune form of this condition, in particular, is treatable.

This study describes the incidence, clinical features, diagnostic testing, and treatment trends of pediatric myasthenia in Canada, which have not been previously reported in the literature. (Read the full article)

The prevalence of overweight and obesity in US adolescents has increased over the last century. However, recent evidence indicates a potential change in this trend. Parallel trends in adolescent behaviors that drive this epidemic have not been well studied.

Analyses of recent data indicate the prevalence of overweight and obesity may be stabilizing. Over the same period, adolescent physical activity, breakfast eating, and fruit and vegetable consumption increased and television viewing and consumption of sweets and sweetened beverages decreased.

Previous studies have shown that nonmedical exemptions (NMEs) to immunization cluster geographically and contribute to outbreaks of vaccine-preventable diseases such as pertussis. The 2010 pertussis resurgence in California has been widely attributed to waning immunity from acellular pertussis vaccines.

This study provides evidence of spatial and temporal clustering of NMEs and clustering of pertussis cases and suggests that geographic areas with high NME rates were also associated with high rates of pertussis in California in 2010. (Read the full article)

Caregiver behavioral symptom ratings are frequently used to assist in diagnosing childhood behavioral disorders. Although behavioral disorders are highly comorbid with learning disabilities (LDs), little work has examined the utility of caregiver ratings of learning concerns for screening of comorbid LD.

The validity of a time- and cost-efficient caregiver rating of academic concerns (Colorado Learning Difficulties Questionnaire) was examined. The screening measure accurately predicted children without LD, suggesting that the absence of parent-reported difficulties may be adequate to rule out overt LD. (Read the full article)

Prenatal exposures to diverse pollutants and psychosocial stressors have been shown independently to adversely affect child development. Less is known about the potential interactions between these factors, although they commonly co-occur, especially in disadvantaged populations.

The combination of high prenatal exposure to environmental polycyclic aromatic hydrocarbons and maternal demoralization adversely affects child behavior, and maternal demoralization has a greater effect among children with high prenatal polycyclic aromatic hydrocarbon exposure for a majority of behavioral symptoms.

In January 2006, a public health advisory and boxed warning for long-term safety and the risk of malignancies and a medication guide were issued for topical calcineurin inhibitors, tacrolimus and pimecrolimus.

Evaluation of off-label use of topical calcineurin inhibitors in children before and after regulatory action by the Food and Drug Administration is important to understand the impact of regulatory action. (Read the full article)

Physical activity (PA) levels in preschool children vary considerably between preschools, and are positively associated with the overall quality of the preschool. However, knowledge regarding specific characteristics of the preschool environment hypothesized to promote PA is inconsistent and lacking.

This study tested multiple potential correlates of preschool children’s objectively measured moderate and vigorous PA level during preschool attendance, identifying size of indoor area per child and location of preschool building on the playground as new potentially modifiable correlates.

Unintentional overdose and emergency department visits secondary to nonmedical use of prescription drugs are on the rise with peak age of onset in midadolescence for these risk behaviors. Also, risk behaviors, such as substance use and violence, tend to cluster.

Approximately 1 in 10 adolescents or young adults using the emergency department endorse nonmedical prescription opioid or sedative use in the past year. Rates of current opioid or sedative prescriptions are low among this group. (Read the full article)

It has previously been shown that exposure to intimate partner violence and/or parental depression or anxiety may increase a child’s risk for specific adverse health outcomes.

By using a large pediatric primary care sample, this study examined associations of child exposure to intimate partner violence and parental psychological distress with developmental milestone attainment by analyzing their combined and separate effects while adjusting for other family factors.

Levels of daily physical activity in children are decreasing worldwide. This implies risk factors for cardiovascular and metabolic diseases.

Strength training makes children not only stronger but significantly increases their daily spontaneous physical activity outside the training intervention. (Read the full article)

Children with autism spectrum disorders (ASD) or attention-deficit/hyperactivity disorder (ADHD) are at increased risk for sleep disturbances and excessive media use. However, the relationship between media use and sleep in children with ASD or ADHD has not been studied.

In-room access to screen-based media and video game hours were associated with less sleep among boys with ASD. The relationships between media use and sleep were much more pronounced among boys with ASD than among boys with ADHD or typical development. (Read the full article)

Few data on treating children hospitalized for influenza with neuraminidase inhibitors are available, contributing to uncertainty regarding the benefits of treatment.

This study of nearly 800 critically ill children suggests that treatment with neuraminidase inhibitors improves survival from influenza. This message needs additional emphasis, given that in the past 2 seasons over one-third of cases did not receive antiviral treatment. (Read the full article)

Pediatric surgery is performed in a variety of hospital types. General surgeons as well as fellowship-trained pediatric surgeons and surgical subspecialists perform inpatient operative procedures on infants and children. The distribution of procedures between specialists is not well characterized.

This study describes the demographics of pediatric surgery: the hospital type, the surgical procedures, and the quantity of inpatient pediatric surgery in the U.S. today. By implication, the data has much to inform health care about hospital and practitioner workforce. (Read the full article)

Fewer clinical trials are performed in children compared with other patient populations. It is unknown how well existing pediatric clinical trials are aligned with the needs of children, both in high-income countries and globally.

There is only moderate correlation between clinical trial activity and pediatric burden of disease, with certain conditions substantially underrepresented in the current research portfolio. Our findings provide a benchmark for prioritizing conditions for study, analyzing gaps, and identifying funding priorities. (Read the full article)

Although appendicitis is the most common surgical cause of abdominal pain in pediatrics, its diagnosis remains elusive. When evaluated independently, clinical scoring systems and ultrasonography have been shown to have low to moderate sensitivity in the diagnosis of appendicitis.

Our study evaluated the accuracy of a clinical practice guideline combining the Samuel’s pediatric appendicitis score and selective ultrasonography as the primary imaging modality for children with suspected appendicitis. Our clinical pathway demonstrated high sensitivity and specificity. (Read the full article)

The effects of previous school-based physical activity promotion interventions have been modest, and none have demonstrated significant or meaningful increases in children’s physical activity outside of school, a period characterized by disproportionally low levels of physical activity in youth.

This study adds to the evidence-base for the effectiveness of comprehensive school health programs by demonstrating that such novel interventions lead to statistically significant, meaningful increases in the amount of physical activity children achieved on weekends and after school hours. (Read the full article)

Fetal growth restriction, particularly in preterm children, is associated with delayed development and poor growth. Knowledge about the consequences of fetal growth restriction if classified by symmetry is lacking, especially in preterm children.

In preterm children, symmetric and asymmetric growth restriction at birth results in poorer growth later in life. Both groups are at considerable risk of developmental delay because their long-term development is independent of their head circumference at birth. (Read the full article)

The American Academy of Pediatrics (AAP) and other organizations have recommended critical congenital heart disease (CCHD) pulse oximetry screening. Small studies have revealed lower saturations at higher altitude, but this effect on CCHD screening is unknown. The AAP requested additional studies at altitude to help clarify the dilemma.

The AAP has endorsed higher-altitude studies of CCHD screening. This observational prospective study revealed a higher positive screen rate at moderate altitude than at sea level. These findings suggest that current national recommendations may result in increased screening failures at moderate altitude. (Read the full article)

Drug use in pediatrics is often based on adult efficacy data. Clinically significant discrepancies between adults and children may exist. To our knowledge, there is no large-scale evaluation of evidence comparing rates of adverse events between adults and children.

Available evidence on the comparative safety of pharmacologic interventions in adults versus children is inconclusive. In a third of meta-analyses, twofold or greater differences were identified between adults and children, and some clinically important discrepancies were also found. (Read the full article)

Quantitative real-time polymerase chain reaction allows sensitive detection of respiratory viruses. The clinical significance of detection of specific viruses is not fully understood, however, and several viruses have been detected in the respiratory tract of asymptomatic children.

Our results indicate that quantitative real-time polymerase chain reaction is limited at distinguishing acute infection from detection in asymptomatic children for rhinovirus, bocavirus, adenovirus, enterovirus, and coronavirus. (Read the full article)

Individuals living in Mediterranean countries have historically had a lower risk of cardiovascular disease. Important changes in diet and lifestyle have taken place in these countries in recent years, and it is unknown how these changes might influence current cardiovascular health.

Fitness and fatness levels indicate that urban adolescents from southern Europe are less healthy than those from central northern Europe. The extent to which these differences might be explained by physical activity, diet, and genetics is analyzed and discussed in this article. (Read the full article)

The familial nature of vesicoureteral reflux (VUR) is well recognized. Several studies have shown that siblings of children with VUR are at much higher risk for reflux than the general pediatric population with a reported prevalence between 26% and 50%.

There is increased risk of renal cortical abnormalities in siblings with a previous urinary tract infection, siblings with high-grade VUR, and siblings >1 year of age. This information may be useful when counseling parents about the risk of familial VUR. (Read the full article)

Physical activity interventions aimed at improving body composition in childhood have had limited success and often targeted overweight children. Therefore, the efficacy of physical activity randomized controlled trials in improving body composition among children with varying adiposity levels remains unknown.

This randomized controlled trial demonstrated that a physical activity program designed to meet daily physical activity recommendations can improve cardiorespiratory fitness, decrease total fat mass, and prevent accumulation of central adiposity in a group of children with varying adiposity levels.

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

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

Scabies is a frequent cause of consultation and has recently been classified as a neglected disease. The clinical presentation seems to be linked with age, although no specific study has aimed to delineate the clinical spectrum of scabies in infants and children.

Scabies in infants and children has distinct clinical features. This prospective observational study found that infants were more likely to have relapse, nodules, and to present involvement with extremities, face, and scalp, arguing for specific cares in this age group. (Read the full article)

Practice standards for managing adult cervical spine injuries (CSIs) are well established. However, pediatric CSIs are rare and different from those of adults, preventing extrapolation from adult practice and illustrating the need for larger multicenter investigations of CSIs in children.

This study comprehensively describes CSIs in a large multicenter pediatric cohort. The large number of young children included allowed us to comprehensively explore the relationship between CSI pattern and age, mechanism of injury, comorbid injuries, surgical interventions, and neurologic outcome.

Quality measures developed by the Pediatric Quality Measures Program are required to assess disparities in performance according to special health care need status. Methods are needed to identify children according to level of medical complexity in administrative data.

The Pediatric Medical Complexity Algorithm is a new, publicly available algorithm that identifies the small proportion of children with complex chronic disease in Medicaid claims and hospital discharge data with good sensitivity and good to excellent specificity. (Read the full article)

Injuries sustained by parents in combat can also have a variety of psychological effects on children in the family. However, there has been little research on the effect of parental injury on children in the civilian setting.

The effects of injury of parents impacted children’s functioning by negatively affecting the health-related quality of life of the injured children, over and above the effect of any injury itself to the child. Injury to the parent also increased the likelihood of his or her uninjured children having PTSD symptoms 5 months after the parent’s injury. (Read the full article)

Children with shaken-baby syndrome, or abusive head trauma (AHT), have lasting health and development problems. The long-term medical cost of AHT is unknown.

Patients with AHT had higher inpatient, outpatient, and drug costs compared with other children for 4 years after their abuse diagnosis, amounting to tens of thousands of dollars in excess and preventable medical care per patient with AHT. (Read the full article)

Early referral of infants with critical congenital heart disease (CCHD) is recommended to reduce mortality. However, few population-based data have been published showing the relationship between CCHD neonatal mortality and timing of cardiac evaluation at a specialty center.

In neonates with CCHD, 35% were not evaluated at a cardiac center by 4 days of age. These cases accounted for a significant number of CCHD deaths. This information enhances the rationale for pulse oximetry screening of neonates for CCHD. (Read the full article)

Predicting high-risk populations in congenital diaphragmatic hernia (CDH) can help target care strategies. Prediction rules for infants with CDH often lack validation, are aimed at a prenatal population, and are of limited generalizability. We cannot currently discriminate the highest risk neonates during the crucial period shortly after birth.

This clinical prediction rule was developed and validated on an international database. It discriminates patients and high, intermediate, and low risk of mortality; is easy to apply; and is generalizable to most infants with CDH. (Read the full article)

Pediatricians need to treat overweight in early childhood. Family-based interventions in specialized clinics are efficacious in children age 8 years and older. Data regarding treatment of younger children are limited in specialty clinics and primary care.

This study shows that a 12-month family-based behavioral intervention in primary care is more efficacious compared with Control condition with a child-only focus. Weight outcome differences between Intervention and Control persist in children and parents after a 12-month follow-up. (Read the full article)

Numerous studies have demonstrated clinical benefits of medical emergency team (MET) implementation, including reductions in mortality, cardiac arrests, and critical deterioration events. No studies have evaluated the financial costs and benefits of METs.

The costs of operating an MET can plausibly be recouped with a modest reduction in critical deterioration events. Hospitals reimbursed with bundled payments could see real financial savings by reducing critical deterioration events with a MET. (Read the full article)

Delayed diagnosis of critical congenital heart defects (CCHDs) is associated with increased morbidity and mortality.

Despite increasing prenatal diagnosis rates, delayed diagnosis of CCHDs continues to occur, with rates highest among isolated cases and those delivered at nontertiary care hospitals. Better understanding of delayed diagnosis could help to improve screening efforts. (Read the full article)

Several studies have revealed an association between cesarean section (CS) and childhood type 1 diabetes. Most of these studies lacked important information on indication for CS and induction of labor. It is unknown whether the reported associations are causal.

Using a cohort of 2.6 million children we found an association between elective CS and type 1 diabetes. The sibling analysis suggested the association is not causal. The findings are crucial evidence to advise women on mode of delivery choice. (Read the full article)
